Subject: Bluetooth: hci_qca: Fix an error pointer dereference

When a function like devm_clk_get_optional() function returns both error
pointers on error and NULL then the NULL return means that the optional
feature is deliberately disabled.  It is a special sort of success and
should not trigger an error message.  The surrounding code should be
written to check for NULL and not crash.

On the other hand, if we encounter an error, then the probe from should
clean up and return a failure.

In this code, if devm_clk_get_optional() returns an error pointer then
the kernel will crash inside the call to:

	clk_set_rate(qcadev->susclk, SUSCLK_RATE_32KHZ);

The error handling must be updated to prevent that.

Subject: iwlwifi: Extended Key ID support for mvm and dvm

All iwlwifi cards below the 22000 series are able to handle multiple
keyids per STA and allow the selection of the encryption key per MPDU.

These are therefore fully compatible with the Extended Key ID support
implementation in mac80211.

Enable Extended Key ID support for all dvm cards and the mvm cards not
using the incompatible new Tx API introduced for the 22000 series.

IWL_WARN seems excessive here since this can happen during normal

this as KERN_WARNING on the console, which mildly distracts from other
more pressing messages. For example:

Subject: Bluetooth: hci_qca: Simplify determination of serial clock on/off
 state from votes

The serial clocks should be on when there is a vote for at least one
of the clocks (RX or TX), and off when there is no 'on' vote. The
current logic to determine the combined state is a bit redundant
in the code paths for different types of votes, use a single
statement in the common path instead.

Subject: Bluetooth: hci_qca: Only remove TX clock vote after TX is completed

qca_suspend() removes the vote for the UART TX clock after
writing an IBS sleep request to the serial buffer. This is
not a good idea since there is no guarantee that the request
has been sent at this point. Instead remove the vote after
successfully entering IBS sleep. This also fixes the issue
of the vote being removed in case of an aborted suspend due
to a failure of entering IBS sleep.

Subject: Bluetooth: hci_qca: Skip serdev wait when no transfer is pending

qca_suspend() calls serdev_device_wait_until_sent() regardless of
whether a transfer is pending. While it does no active harm since
the function should return immediately it makes the code more
confusing. Add a flag to track whether a transfer is pending and
only call serdev_device_wait_until_sent() is needed.

Subject: Bluetooth: Allow suspend even when preparation has failed

It is preferable to allow suspend even when Bluetooth has problems
preparing for sleep. When Bluetooth fails to finish preparing for
suspend, log the error and allow the suspend notifier to continue
instead.

To also make it clearer why suspend failed, change bt_dev_dbg to
bt_dev_err when handling the suspend timeout.

Change this structure to use a flexible-array member for 'tfd' instead,

Subject: Bluetooth: hci_qca: Bug fix during SSR timeout

Due to race conditions between qca_hw_error and qca_controller_memdump
during SSR timeout,the same pointer is freed twice. This results in a
double free. Now a lock is acquired before checking the stauts of SSR
state.

Subject: iwlwifi: Replace zero-length array with flexible-array

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

Subject: ath11k: Use freq instead of channel number in rx path

As 6GHz cahnnel numbers overlap with those of 5GHz and 2GHz bands,
it is necessary to use frequency when determining the band info
in rx path.

This adds support required for configuring min_data_rate of 6GHz oper IE
and peer_he_caps_6ghz in peer assoc command. The Minimum Rate field
indicates the minimum rate, in units of 1 Mb/s, that the non-AP STA is
allowed to use for sending PPDUs as defined in IEEE P802.11ax™/D6.0.

If 6 ghz channel is a Preferred Scanning Channel(PSC), mark
the channel flag accordingly when updating channel list to firmware.
This will be used when making scanning decision in 6GHz channels.

Subject: ath11k: Send multiple scan_chan_list messages if required

With addition of 6Ghz channels, it is possible that wmi buffer size can
exceed the maximum wmi buffer size. So iterate over the channel list,
and send multiple messages till channel list is empty.
Also mark PSC channel flag for 6GHz channels accordingly.

Set the correct parent dev when registering hdev. This allows userspace
tools to find the parent device (for example, to set the power/wakeup
property).

Before this change, the path was /sys/devices/virtual/bluetooth/hci0
and after this change, it looks more like:
/sys/bus/mmc/devices/mmc1:0001/mmc1:0001:2/bluetooth/hci0

Subject: Bluetooth: Add support for BT_PKT_STATUS CMSG data for SCO
 connections

This change adds support for reporting the BT_PKT_STATUS to the socket
CMSG data to allow the implementation of a packet loss correction on
erroneous data received on the SCO socket.

The patch was partially developed by Marcel Holtmann and validated by
Hsin-yu Chao.

Subject: Bluetooth: hci_qca: Request Tx clock vote off only when Tx is pending

Tx pending flag is set to true when HOST IBS state is AWAKE or
AWAKEING. If IBS state is ASLEEP, then Tx clock is already voted
off. To optimize further directly calling serial_clock_vote()
instead of qca_wq_serial_tx_clock_vote_off(), at this point of
qca_suspend() already data is sent out. No need to wake up hci to
send data.

Subject: ath11k: Add direct buffer ring support

Add direct buffer ring (dbring) with helper API, which is used by the
spectral scan. Initialise the direct buffer ring based on the dma ring
capability, which get announced in the wmi service ready extended event.
This ring is slightly changed from data path rings. Compare to data path
ring this ring shares the hp and tp address to firmware though WMI commands.
Also the replenish buffer size is derived from firmware announcement.
driver receive indication through WMI event
WMI_PDEV_DMA_RING_BUF_RELEASE_EVENTID.

Tested-on: IPQ8074 WLAN.HK.2.1.0.1-01228-QCAHKSWPL_SILICONZ-1

Subject: ath11k: add support for spectral scan

spectral scan control interface is exposed through debugfs eentry.
Relayfs is used to collect the spectral data. These interfaces are
similar to ath10k spectral.

spectral debugfs interfaces are below,

echo background > /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan_ctl
echo trigger > /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan_ctl
iw dev wlan0 scan
echo disable > /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan_ctl
cat /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan0 > fft_samples.dump

Tested-on: IPQ8074 WLAN.HK.2.1.0.1-01228-QCAHKSWPL_SILICONZ-1

Subject: ath11k: Add dp tx err stats

Add support for dp tx error stats which logs tx failure reasons due
to ring full condition, etc. This stats is added in soc_dp_stats
which was earlier used as soc_rx_stats so that all dp related info
are logged in same file.

Below is an example usage,

root@OpenWrt:/# cat /sys/kernel/debug/ath11k/ipq8074/soc_dp_stats
SOC RX STATS:

err ring pkts: 0
Invalid RBM: 0
<snip>

SOC TX STATS:

Ring Full Failures:
ring0: 4
ring1: 3
ring2: 5

Misc Transmit Failures: 2

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01213-QCAHKSWPL_SILICONZ-1

Subject: ath11k: Add support for ring backpressure stats

Add support for collecting and dumping the ring backpressure
stats via debugfs. Stats are dumped only if events are
received for the specific ring.

Below command can be used to obtain these stats as part of soc dp stats.
cat /sys/kernel/debug/ath11k/ipq8074/soc_dp_stats

 Sample Output - When No stats available:

 Backpressure Stats
 ==================
 No Ring Backpressure stats received

 Sample Output -  When ring bp stats available for specific ring

 Backpressure Stats
 ==================
 Ring: REO2SW1_RING
 count: 1
 hp: 2
 tp: 2
 seen before: 4ms

Subject: ath11k: fix wmi peer flags in peer assoc command

Currently need ptk/gtk wmi peer flags in wmi peer assoc cmd
are set based on the rsnie and wpaie of the bss from the bss list.
Since this bss list is not updated with current BSSID for AP mode,
we may not find bss from the bss list. Which results in ptk/gtk peer
flags are not set in the wmi peer assoc cmd. Due to this EAPOL frames
are going in data rates instead of management rates.

Tested-on: IPQ8074 WLAN.HK.2.1.0.1-01228-QCAHKSWPL_SILICONZ-1

Subject: tipc: update a binding service via broadcast

Currently, updating binding table (add service binding to
name table/withdraw a service binding) is being sent over replicast.
However, if we are scaling up clusters to > 100 nodes/containers this
method is less affection because of looping through nodes in a cluster one
by one.

It is worth to use broadcast to update a binding service. This way, the
binding table can be updated on all peer nodes in one shot.

Broadcast is used when all peer nodes, as indicated by a new capability
flag TIPC_NAMED_BCAST, support reception of this message type.

Four problems need to be considered when introducing this feature.
1) When establishing a link to a new peer node we still update this by a
unicast 'bulk' update. This may lead to race conditions, where a later
broadcast publication/withdrawal bypass the 'bulk', resulting in
disordered publications, or even that a withdrawal may arrive before the
corresponding publication. We solve this by adding an 'is_last_bulk' bit
in the last bulk messages so that it can be distinguished from all other
messages. Only when this message has arrived do we open up for reception
of broadcast publications/withdrawals.

2) When a first legacy node is added to the cluster all distribution
will switch over to use the legacy 'replicast' method, while the
opposite happens when the last legacy node leaves the cluster. This
entails another risk of message disordering that has to be handled. We
solve this by adding a sequence number to the broadcast/replicast
messages, so that disordering can be discovered and corrected. Note
however that we don't need to consider potential message loss or
duplication at this protocol level.

3) Bulk messages don't contain any sequence numbers, and will always
arrive in order. Hence we must exempt those from the sequence number
control and deliver them unconditionally. We solve this by adding a new
'is_bulk' bit in those messages so that they can be recognized.

4) Legacy messages, which don't contain any new bits or sequence
numbers, but neither can arrive out of order, also need to be exempt
from the initial synchronization and sequence number check, and
delivered unconditionally. Therefore, we add another 'is_not_legacy' bit
to all new messages so that those can be distinguished from legacy
messages and the latter delivered directly.

v1->v2:
 - fix warning issue reported by kbuild test robot <lkp@intel.com>
 - add santiy check to drop the publication message with a sequence
number that is lower than the agreed synch point

Subject: liquidio: Replace vmalloc_node + memset with vzalloc_node and use
 array_size

Use vzalloc/vzalloc_node instead of the vmalloc/vzalloc_node and memset.

Also, notice that vzalloc_node() function has no 2-factor argument form
to calculate the size for the allocation, so multiplication factors need
to be wrapped in array_size().

This issue was found with the help of Coccinelle and, audited and fixed
manually.

Subject: Bluetooth: Add get/set device flags mgmt op

Add the get device flags and set device flags mgmt ops and the device
flags changed event. Their behavior is described in detail in
mgmt-api.txt in bluez.

Sample btmon trace when a HID device is added (trimmed to 75 chars):

Subject: Bluetooth: Add handler of MGMT_OP_READ_ADV_MONITOR_FEATURES

This adds the request handler of MGMT_OP_READ_ADV_MONITOR_FEATURES
command. Since the controller-based monitoring is not yet in place, this
report only the supported features but not the enabled features.

The following test was performed.
- Issuing btmgmt advmon-features.

Subject: Bluetooth: Add handler of MGMT_OP_ADD_ADV_PATTERNS_MONITOR

This adds the request handler of MGMT_OP_ADD_ADV_PATTERNS_MONITOR command.
Note that the controller-based monitoring is not yet in place. This tracks
the content of the monitor without sending HCI traffic, so the request
returns immediately.

The following manual test was performed.
- Issue btmgmt advmon-add with valid and invalid inputs.
- Issue btmgmt advmon-add more the allowed number of monitors.

- Start two btmgmt consoles, issue a btmgmt advmon-remove command on one
console and observe a MGMT_EV_ADV_MONITOR_REMOVED event on the other.

Subject: Bluetooth: Update background scan and report device based on
 advertisement monitors

This calls hci_update_background_scan() when there is any update on the
advertisement monitors. If there is at least one advertisement monitor,
the filtering policy of scan parameters should be 0x00. This also reports
device found mgmt events if there is at least one monitor.

The following cases were tested with btmgmt advmon-* commands.
(1) add a ADV monitor and observe that the passive scanning is
triggered.
(2) remove the last ADV monitor and observe that the passive scanning is
terminated.
(3) with a LE peripheral paired, repeat (1) and observe the passive
scanning continues.
(4) with a LE peripheral paired, repeat (2) and observe the passive
scanning continues.
(5) with a ADV monitor, suspend/resume the host and observe the passive
scanning continues.

Subject: Bluetooth: Terminate the link if pairing is cancelled

If user decides to cancel the ongoing pairing process (e.g. by clicking
the cancel button on pairing/passkey window), abort any ongoing pairing
and then terminate the link if it was created because of the pair
device action.

Subject: bpf: sk_storage: Prefer to get a free cache_idx

The cache_idx is currently picked by RR.  There is chance that
the same cache_idx will be picked by multiple sk_storage_maps while
other cache_idx is still unused.  e.g. It could happen when the
sk_storage_map is recreated during the restart of the user
space process.

This patch tracks the usage count for each cache_idx.  There is
16 of them now (defined in BPF_SK_STORAGE_CACHE_SIZE).
It will try to pick the free cache_idx.  If none was found,
it would pick one with the minimal usage count.

Whenever a buggy NAPI driver returns more than its budget,
we emit a stack trace that is of no use, since it does not
tell which driver is buggy.

Instead, emit a message giving the function name, and a
descriptive message.

Subject: r8169: improve setting WoL on runtime-resume

In the following scenario WoL isn't configured properly:
- Driver is loaded, interface isn't brought up within 10s, so driver
  runtime-suspends.
- WoL is set.
- Interface is brought up, stored WoL setting isn't applied.

It has always been like that, but the scenario seems to be quite
theoretical as I haven't seen any bug report yet. Therefore treat
the change as an improvement.

Subject: mISDN: hfcsusb: Use struct_size() helper

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.

This code was detected with the help of Coccinelle and, audited and
fixed manually.

Right now they are empty functions for our SoC since hardware can keep
cache coherent, but it is still good to align with streaming DMA APIs
as device drivers should not make an assumption of SoC.

Subject: octeontx2-af: change (struct qmem)->entry_sz from u8 to u16

We need to increase TSO_HEADER_SIZE from 128 to 256.

Since otx2_sq_init() calls qmem_alloc() with TSO_HEADER_SIZE,
we need to change (struct qmem)->entry_sz to avoid truncation to 0.

Subject: net: tso: double TSO_HEADER_SIZE value

Transport header size could be 60 bytes, and network header
size can also be 60 bytes. Add the Ethernet header and we
are above 128 bytes.

Since drivers using net/core/tso.c usually allocates
one DMA coherent piece of memory per TX queue, this patch
might cause issues if a driver was using too many slots.

For 1024 slots, we would need 256 KB of physically
contiguous memory instead of 128 KB.

Alternative fix would be to add checks in the fast path,
but this involves more work in all drivers using net/core/tso.c.

Subject: net: tso: cache transport header length

Add tlen field into struct tso_t, and change tso_start()
to return skb_transport_offset(skb) + tso->tlen

This removes from callers the need to use tcp_hdrlen(skb) and
will ease UDP segmentation offload addition.

v2: calls tso_start() earlier in otx2_sq_append_tso() [Jakub]

Subject: cxgb4: update set_flash to flash different images

Chelsio adapter contains different flash regions and each
region is used by different binary files. This patch adds
support to flash images like PHY firmware, boot and boot config
using ethtool -f N.

The N value mapping is as follows.
N = 0 : Parse image and decide which region to flash
N = 1 : Firmware
N = 2 : PHY firmware
N = 3 : boot image
N = 4 : boot cfg

Subject: net: qos offload add flow status with dropped count

This patch adds a drop frames counter to tc flower offloading.
Reporting h/w dropped frames is necessary for some actions.
Some actions like police action and the coming introduced stream gate
action would produce dropped frames which is necessary for user. Status
update shows how many filtered packets increasing and how many dropped
in those packets.

v2: Changes
 - Update commit comments suggest by Jiri Pirko.

Subject: cxgb4: add ethtool n-tuple filter insertion

Add support to parse and insert ethtool n-tuple filters.
Translate n-tuple spec to flow spec and use the existing tc-flower
offload infra to insert ethtool n-tuple filters.

Subject: bpf: Avoid verifier failure for 32bit pointer arithmetic

When do experiments with llvm (disabling instcombine and
simplifyCFG), I hit the following error with test_seg6_loop.o.

  ; R1=pkt(id=0,off=0,r=48,imm=0), R7=pkt(id=0,off=40,r=48,imm=0)
  w2 = w7
  ; R2_w=inv(id=0,umax_value=4294967295,var_off=(0x0; 0xffffffff))
  w2 -= w1
  R2 32-bit pointer arithmetic prohibited

The corresponding source code is:
  uint32_t srh_off
  // srh and skb->data are all packet pointers
  srh_off = (char *)srh - (char *)(long)skb->data;

The verifier does not support 32-bit pointer/scalar arithmetic.

Without my llvm change, the code looks like

  ; R3=pkt(id=0,off=40,r=48,imm=0), R8=pkt(id=0,off=0,r=48,imm=0)
  w3 -= w8
  ; R3_w=inv(id=0)

This is explicitly allowed in verifier if both registers are
pointers and the opcode is BPF_SUB.

To fix this problem, I changed the verifier to allow
32-bit pointer/scaler BPF_SUB operations.

At the source level, the issue could be workarounded with
inline asm or changing "uint32_t srh_off" to "uint64_t srh_off".
But I feel that verifier change might be the right thing to do.

Subject: net: phy: clean up cortina workaround

Move the Cortina PHY workaround out of the "devices in package" loop;
it doesn't need to be in there as the control flow will terminate the
loop once we enter the workaround irrespective of the workaround's
outcome. The workaround is triggered by the ID being mostly 1's, which
will in any case terminate the loop.

Rearrange the code to read the PHY IDs, so we don't call get_phy_id()
only to immediately call get_phy_c45_ids().  Move that logic into
get_phy_device(), which results in better readability.

Subject: net: phy: clean up get_phy_c45_ids() failure handling

When we decide that a PHY is not present, we do not need to go through
the hoops of setting *phy_id to 0xffffffff, and then return zero to
make get_phy_device() fail - we can return -ENODEV which will have the
same effect.

Doing so means we no longer have to pass a pointer to phy_id in, and
we can then clean up the clause 22 path in a similar way.

Subject: net: phy: clean up get_phy_c22_id() invalid ID handling

Move the ID check from get_phy_device() into get_phy_c22_id(), which
simplifies get_phy_device(). The ID reading functions are now
responsible for indicating whether they found a PHY or not via their
return code - they must return -ENODEV when a PHY is not present.

Add support for probing MMDs above 7 for a valid devices-in-package
specifier, but only probe the vendor MMDs for this if they also report
that there the device is present in status register 2.  This avoids
issues where the MMD is implemented, but does not provide IEEE 802.3
compliant registers (such as the MV88X3310 PHY.)

Subject: net: phy: split devices_in_package

We have two competing requirements for the devices_in_package field.
We want to use it as a bit array indicating which MMDs are present, but
we also want to know if the Clause 22 registers are present.

Since "devices in package" is a term used in the 802.3 specification,
keep this as the as-specified values read from the PHY, and introduce
a new member "mmds_present" to indicate which MMDs are actually
present in the PHY, derived from the "devices in package" value.

Subject: net: phy: read MMD ID from all present MMDs

Expand the device_ids[] array to allow all MMD IDs to be read rather
than just the first 8 MMDs, but only read the ID if the MDIO_STAT2
register reports that a device really is present here for these new
devices to maintain compatibility with our current behaviour.  Note
that only a limited number of devices have MDIO_STAT2.

88X3310 PHY vendor MMDs do are marked as present in the
devices_in_package, but do not contain IEE 802.3 compatible register
sets in their lower space.  This avoids reading incorrect values as MMD
identifiers.

Make use of the struct_size() helper instead of an open-coded version

Subject: l3mdev: add infrastructure for table to VRF mapping

Add infrastructure to l3mdev (the core code for Layer 3 master devices) in
order to find out the corresponding VRF device for a given table id.
Therefore, the l3mdev implementations:
 - can register a callback that returns the device index of the l3mdev
   associated with a given table id;
 - can offer the lookup function (table to VRF device).

Subject: vrf: track associations between VRF devices and tables

Add the data structures and the processing logic to keep track of the
associations between VRF devices and routing tables.
When a VRF is instantiated, it needs to refer to a given routing table.
For each table, we explicitly keep track of the existing VRFs that refer to
the table.

Subject: vrf: add sysctl parameter for strict mode

Add net.vrf.strict_mode sysctl parameter.

When net.vrf.strict_mode=0 (default) it is possible to associate multiple
VRF devices to the same table. Conversely, when net.vrf.strict_mode=1 a
table can be associated to a single VRF device.

When switching from net.vrf.strict_mode=0 to net.vrf.strict_mode=1, a check
is performed to verify that all tables have at most one VRF associated,
otherwise the switch is not allowed.

The net.vrf.strict_mode parameter is per network namespace.

Subject: net: mscc: ocelot: use plain int when interacting with TCAM tables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

sparse is rightfully complaining about the fact that:

warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
   26 |   __builtin_constant_p((l) > (h)), (l) > (h), 0)))
      |                            ^
note: in expansion of macro ‘GENMASK_INPUT_CHECK’
   39 |  (GENMASK_INPUT_CHECK(h, l) + __GENMASK(h, l))
      |   ^~~~~~~~~~~~~~~~~~~
note: in expansion of macro ‘GENMASK’
  127 |   mask = GENMASK(width, 0);
      |          ^~~~~~~

So replace the variables that go into GENMASK with plain, signed integer
types.

Subject: net: mscc: ocelot: rename module to mscc_ocelot

mscc_ocelot is a slightly better name for a module than ocelot_board or
ocelot_vsc7514 is, so let's use that.

Subject: net: mscc: ocelot: convert MSCC_OCELOT_SWITCH into a library

Hide the CONFIG_MSCC_OCELOT_SWITCH option from users. It is meant to be
only a hardware library which is selected by the drivers that use it
(ocelot, felix).

Since it is "selected" from Kconfig, all its dependencies are manually
transferred to the driver that selects it. This is because "select" in
Kconfig language is a bit of a mess, and doesn't handle dependencies of
selected options quite right.

Subject: net: mscc: ocelot: rename MSCC_OCELOT_SWITCH_OCELOT to
 MSCC_OCELOT_SWITCH

Putting 'ocelot' in the config's name twice just to say that 'it's the
ocelot driver running on the ocelot SoC' is a bit confusing. Instead,
it's just the ocelot driver. Now that we've renamed the previous symbol
that was holding the MSCC_OCELOT_SWITCH_OCELOT into *_LIB (because
that's what it is), we're free to use this name for the driver.

Subject: net: mscc: ocelot: move ocelot_regs.c into ocelot_vsc7514.c

ocelot_regs.c actually shouldn't be part of the common library. It
describes the register map of the VSC7514 switch. The way ocelot
switches work, they'll have highly optimized register maps, so another
SoC will likely have the same registers but laid out completely
different in memory (so there's little room for reusing this structure).
So move it to ocelot_vsc7514.c instead.

From 9c90eea310f80460b81a7afe27064c7f0200d1d1 Mon Sep 17 00:00:00 2001
From: Vladimir Oltean <vladimir.oltean@nxp.com>

Subject: net: mscc: ocelot: move net_device related functions to ocelot_net.c

The ocelot hardware library shouldn't contain too much net_device
specific code, since it is shared with DSA which abstracts that
structure away. So much as much of this code as possible into the
mscc_ocelot driver and outside of the common library.

We're making an exception for MDB and LAG code. That is not yet exported
to DSA, but when it will, most of the code that's already in ocelot.c
will remain there. So, there's no point in moving code to ocelot_net.c
just to move it back later.

We could have moved all net_device code to ocelot_vsc7514.c directly,
but let's operate under the assumption that if a new switchdev ocelot
driver gets added, it'll define its SoC-specific stuff in a new
ocelot_vsc*.c file and it'll reuse the rest of the code.

From 3c83654f246b980cc65f72f5c7b1501470082ede Mon Sep 17 00:00:00 2001
From: Vladimir Oltean <vladimir.oltean@nxp.com>
Date: Sat, 20 Jun 2020 18:43:45 +0300
Subject: net: mscc: ocelot: rename ocelot_ace.{c, h} to ocelot_vcap.{c,h}

Access Control Lists (and their respective Access Control Entries) are
specifically entries in the VCAP IS2, the security enforcement block,
according to the documentation.

Let's rename the files that deal with generic operations on the VCAP
TCAM, so that VCAP IS1 and ES0 can reuse the same code without
confusion.

From aae4e500e106d2ce48d5bdb21210e36efc7460cb Mon Sep 17 00:00:00 2001
From: Vladimir Oltean <vladimir.oltean@nxp.com>
Date: Sat, 20 Jun 2020 18:43:46 +0300
Subject: net: mscc: ocelot: generalize the "ACE/ACL" names

Access Control Lists (and their respective Access Control Entries) are
specifically entries in the VCAP IS2, the security enforcement block,
according to the documentation.
Let's rename the structures and functions to something more generic, so
that VCAP IS1 structures (which would otherwise have to be called
Ingress Classification Entries) can reuse the same code without
confusion.

Some renaming that was done:

struct ocelot_ace_rule -> struct ocelot_vcap_filter
struct ocelot_acl_block -> struct ocelot_vcap_block
enum ocelot_ace_type -> enum ocelot_vcap_key_type
struct ocelot_ace_vlan -> struct ocelot_vcap_key_vlan
enum ocelot_ace_action -> enum ocelot_vcap_action
struct ocelot_ace_stats -> struct ocelot_vcap_stats
enum ocelot_ace_type -> enum ocelot_vcap_key_type
struct ocelot_ace_frame_* -> struct ocelot_vcap_key_*

No functional change is intended.

From c73b0ad36ea316e71b5b599228c9d5906045c235 Mon Sep 17 00:00:00 2001
From: Vladimir Oltean <vladimir.oltean@nxp.com>
Date: Sat, 20 Jun 2020 18:43:47 +0300
Subject: net: mscc: ocelot: unexpose ocelot_vcap_policer_{add,del}

Remove the function prototypes from ocelot_police.h and make these
functions static. We need to move them above their callers. Note that
moving the implementations to ocelot_police.c is not trivially possible
due to dependency on is2_entry_set() which is static to ocelot_vcap.c.

Subject: net: Avoid overwriting valid skb->napi_id

This will be useful to allow busy poll for tunneled traffic. In case of
busy poll for sessions over tunnels, the underlying physical device's
queues need to be polled.

Tunnels schedule NAPI either via netif_rx() for backlog queue or
schedule the gro_cell_poll(). netif_rx() propagates the valid skb->napi_id
to the socket. OTOH, gro_cell_poll() stamps the skb->napi_id again by
calling skb_mark_napi_id() with the tunnel NAPI which is not a busy poll
candidate. This was preventing tunneled traffic to use busy poll. A valid
NAPI ID in the skb indicates it was already marked for busy poll by a
NAPI driver and hence needs to be copied into the socket.

Subject: of: mdio: preserve phy dev_flags in of_phy_connect()

Replace assignment "=" with OR "|=" for "phy->dev_flags" so "dev_flags"
configured in phy probe() function can be preserved.

The idea is similar to commit e7312efbd5de ("net: phy: modify assignment
to OR for dev_flags in phy_attach_direct").

Subject: net: mvpp2: add port support helpers

The mvpp2 code has tests scattered amongst the code to determine
whether the port supports the XLG, and whether the port supports
RGMII mode.

Rather than having these tests scattered, provide a couple of helper
functions, so that future additions can ensure that they get these
tests correct.

Subject: Bluetooth: use configured params for ext adv
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the extended advertisement feature is enabled, a hardcoded min and
max interval of 0x8000 is used.  This patch fixes this issue by using
the configured min/max value.

This was validated by setting min/max in main.conf and making sure the
right setting is applied:

< HCI Command: LE Set Extended Advertising Parameters (0x08|0x0036) plen
25                                          #93 [hci0] 10.953011
…
Min advertising interval: 181.250 msec (0x0122)
Max advertising interval: 181.250 msec (0x0122)
…

Subject: bpf: Switch btf_parse_vmlinux to btf_find_by_name_kind

btf_parse_vmlinux() implements manual search for struct bpf_ctx_convert
since at the time of implementing btf_find_by_name_kind() was not
available.

Later btf_find_by_name_kind() was introduced in 27ae7997a661 ("bpf:
Introduce BPF_PROG_TYPE_STRUCT_OPS"). It provides similar search
functionality and can be leveraged in btf_parse_vmlinux(). Do it.

Subject: bpf: Rename bpf_htab to bpf_shtab in sock_map

There are two different `struct bpf_htab` in bpf code in the following
files:
- kernel/bpf/hashtab.c
- net/core/sock_map.c

It makes it impossible to find proper btf_id by name = "bpf_htab" and
kind = BTF_KIND_STRUCT what is needed to support access to map ptr so
that bpf program can access `struct bpf_htab` fields.

To make it possible one of the struct-s should be renamed, sock_map.c
looks like a better candidate for rename since it's specialized version
of hashtab.

Rename it to bpf_shtab ("sh" stands for Sock Hash).

Subject: bpf: Support access to bpf map fields

There are multiple use-cases when it's convenient to have access to bpf
map fields, both `struct bpf_map` and map type specific struct-s such as
`struct bpf_array`, `struct bpf_htab`, etc.

For example while working with sock arrays it can be necessary to
calculate the key based on map->max_entries (some_hash % max_entries).
Currently this is solved by communicating max_entries via "out-of-band"
channel, e.g. via additional map with known key to get info about target
map. That works, but is not very convenient and error-prone while
working with many maps.

In other cases necessary data is dynamic (i.e. unknown at loading time)
and it's impossible to get it at all. For example while working with a
hash table it can be convenient to know how much capacity is already
used (bpf_htab.count.counter for BPF_F_NO_PREALLOC case).

At the same time kernel knows this info and can provide it to bpf
program.

Fill this gap by adding support to access bpf map fields from bpf
program for both `struct bpf_map` and map type specific fields.

Support is implemented via btf_struct_access() so that a user can define
their own `struct bpf_map` or map type specific struct in their program
with only necessary fields and preserve_access_index attribute, cast a
map to this struct and use a field.

For example:

	struct bpf_map {
		__u32 max_entries;
	} __attribute__((preserve_access_index));

	struct bpf_array {
		struct bpf_map map;
		__u32 elem_size;
	} __attribute__((preserve_access_index));

	struct {
		__uint(type, BPF_MAP_TYPE_ARRAY);
		__uint(max_entries, 4);
		__type(key, __u32);
		__type(value, __u32);
	} m_array SEC(".maps");

	SEC("cgroup_skb/egress")
	int cg_skb(void *ctx)
	{
		struct bpf_array *array = (struct bpf_array *)&m_array;
		struct bpf_map *map = (struct bpf_map *)&m_array;

		/* .. use map->max_entries or array->map.max_entries .. */
	}

Similarly to other btf_struct_access() use-cases (e.g. struct tcp_sock
in net/ipv4/bpf_tcp_ca.c) the patch allows access to any fields of
corresponding struct. Only reading from map fields is supported.

For btf_struct_access() to work there should be a way to know btf id of
a struct that corresponds to a map type. To get btf id there should be a
way to get a stringified name of map-specific struct, such as
"bpf_array", "bpf_htab", etc for a map type. Two new fields are added to
`struct bpf_map_ops` to handle it:
* .map_btf_name keeps a btf name of a struct returned by map_alloc();
* .map_btf_id is used to cache btf id of that struct.

To make btf ids calculation cheaper they're calculated once while
preparing btf_vmlinux and cached same way as it's done for btf_id field
of `struct bpf_func_proto`

While calculating btf ids, struct names are NOT checked for collision.
Collisions will be checked as a part of the work to prepare btf ids used
in verifier in compile time that should land soon. The only known
collision for `struct bpf_htab` (kernel/bpf/hashtab.c vs
net/core/sock_map.c) was fixed earlier.

Both new fields .map_btf_name and .map_btf_id must be set for a map type
for the feature to work. If neither is set for a map type, verifier will
return ENOTSUPP on a try to access map_ptr of corresponding type. If
just one of them set, it's verifier misconfiguration.

Only `struct bpf_array` for BPF_MAP_TYPE_ARRAY and `struct bpf_htab` for
BPF_MAP_TYPE_HASH are supported by this patch. Other map types will be
supported separately.

The feature is available only for CONFIG_DEBUG_INFO_BTF=y and gated by
perfmon_capable() so that unpriv programs won't have access to bpf map
fields.

Subject: selftests/bpf: Test access to bpf map pointer

Add selftests to test access to map pointers from bpf program for all
map types except struct_ops (that one would need additional work).

verifier test focuses mostly on scenarios that must be rejected.

prog_tests test focuses on accessing multiple fields both scalar and a
nested struct from bpf program and verifies that those fields have
expected values.

From 1bdb6c9a1c43fdf9b83b2331dfc6229bd2e71d9b Mon Sep 17 00:00:00 2001

Subject: libbpf: Add a bunch of attribute getters/setters for map definitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a bunch of getter for various aspects of BPF map. Some of these attribute
(e.g., key_size, value_size, type, etc) are available right now in struct
bpf_map_def, but this patch adds getter allowing to fetch them individually.
bpf_map_def approach isn't very scalable, when ABI stability requirements are
taken into account. It's much easier to extend libbpf and add support for new
features, when each aspect of BPF map has separate getter/setter.

Getters follow the common naming convention of not explicitly having "get" in
its name: bpf_map__type() returns map type, bpf_map__key_size() returns
key_size. Setters, though, explicitly have set in their name:
bpf_map__set_type(), bpf_map__set_key_size().

This patch ensures we now have a getter and a setter for the following
map attributes:
  - type;
  - max_entries;
  - map_flags;
  - numa_node;
  - key_size;
  - value_size;
  - ifindex.

bpf_map__resize() enforces unnecessary restriction of max_entries > 0. It is
unnecessary, because libbpf actually supports zero max_entries for some cases
(e.g., for PERF_EVENT_ARRAY map) and treats it specially during map creation
time. To allow setting max_entries=0, new bpf_map__set_max_entries() setter is
added. bpf_map__resize()'s behavior is preserved for backwards compatibility
reasons.

Map ifindex getter is added as well. There is a setter already, but no
corresponding getter. Fix this assymetry as well. bpf_map__set_ifindex()
itself is converted from void function into error-returning one, similar to
other setters. The only error returned right now is -EBUSY, if BPF map is
already loaded and has corresponding FD.

One lacking attribute with no ability to get/set or even specify it
declaratively is numa_node. This patch fixes this gap and both adds
programmatic getter/setter, as well as adds support for numa_node field in
BTF-defined map.

Subject: net/devlink: Support querying hardware address of port function

PCI PF and VF devlink port can manage the function represented by
a devlink port.

Enable users to query port function's hardware address.

Example of a PCI VF port which supports a port function:
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1
  function:
    hw_addr 00:11:22:33:44:66

$ devlink port show pci/0000:06:00.0/2 -jp
{
    "port": {
        "pci/0000:06:00.0/2": {
            "type": "eth",
            "netdev": "enp6s0pf0vf1",
            "flavour": "pcivf",
            "pfnum": 0,
            "vfnum": 1,
            "function": {
                "hw_addr": "00:11:22:33:44:66"
            }

Subject: net/devlink: Support setting hardware address of port function

PCI PF and VF devlink port can manage the function represented by a
devlink port.

Allow users to set port function's hardware address.

Example of a PCI VF port which supports a port function:
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1
  function:
    hw_addr 00:00:00:00:00:00

$ devlink port function set pci/0000:06:00.0/2 hw_addr 00:11:22:33:44:55

$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1
  function:
    hw_addr 00:11:22:33:44:55

Subject: xfrm: bail early on slave pass over skb

This is prep work for initial support of bonding hardware encryption
pass-through support. The bonding driver will fill in the slave_dev
pointer, and we use that to know not to skb_push() again on a given
skb that was already processed on the bond device.

Subject: ixgbe_ipsec: become aware of when running as a bonding slave

Slave devices in a bond doing hardware encryption also need to be aware
that they're slaves, so we operate on the slave instead of the bonding
master to do the actual hardware encryption offload bits.

Subject: mlx5: become aware of when running as a bonding slave

I've been unable to get my hands on suitable supported hardware to date,
but I believe this ought to be all that is needed to enable the mlx5
driver to also work with bonding active-backup crypto offload passthru.

Subject: bonding: support hardware encryption offload to slaves

Currently, this support is limited to active-backup mode, as I'm not sure
about the feasilibity of mapping an xfrm_state's offload handle to
multiple hardware devices simultaneously, and we rely on being able to
pass some hints to both the xfrm and NIC driver about whether or not
they're operating on a slave device.

I've tested this atop an Intel x520 device (ixgbe) using libreswan in
transport mode, succesfully achieving ~4.3Gbps throughput with netperf
(more or less identical to throughput on a bare NIC in this system),
as well as successful failover and recovery mid-netperf.

v2: just use CONFIG_XFRM_OFFLOAD for wrapping, isolate more code with it

Subject: net: dsa: qca8k: Improve SGMII interface handling

This patch improves the handling of the SGMII interface on the QCA8K
devices. Previously the driver did no configuration of the port, even if
it was selected. We now configure it up in the appropriate
PHY/MAC/Base-X mode depending on what phylink tells us we are connected
to and ensure it is enabled.

Tested with a device where the CPU connection is RGMII (i.e. the common
current use case) + one where the CPU connection is SGMII. I don't have
any devices where the SGMII interface is brought out to something other
than the CPU.

Subject: net: dsa: sja1105: remove empty structures from config table ops

Sparse is complaining and giving the following warning message:
'Using plain integer as NULL pointer'.

This is not what's going on, instead {0} is used as a zero initializer
for the structure members, to indicate that the particular chip revision
does not support those particular config tables.

But since the config tables are declared globally, the unpopulated
elements are zero-initialized anyway. So, to make sparse shut up, let's
remove the zero initializers.

Subject: net: dsa: sja1105: make config table operation structures constant

The per-chip instantiations of struct sja1105_table_ops and struct
sja1105_dynamic_table_ops can be made constant, so do that.

Subject: net: dsa: sja1105: make the instantiations of struct sja1105_info
 constant

Since struct sja1105_private only holds a const pointer to one of these
structures based on device tree compatible string, the structures
themselves can be made const.

Also add an empty line between each structure definition, to appease
checkpatch.

Amlogic Meson G12A, G12B and SM1 have the same (at least as far as we
know at the time of writing) PRG_ETHERNET glue register implementation.
This implementation however is slightly different from AXG as it now has
an undocument "auto cali idx val" register in PRG_ETH1[17:16] which
seems to be related to RGMII Ethernet.

Add a compatible string for G12A and newer so the new registers can be
used.

Subject: net: core: try to runtime-resume detached device in __dev_open

A netdevice may be marked as detached because the parent is
runtime-suspended and not accessible whilst interface or link is down.
An example are PCI network devices that go into PCI D3hot, see e.g.
__igc_shutdown() or rtl8169_net_suspend().
If netdevice is down and marked as detached we can only open it if
we runtime-resume it before __dev_open() calls netif_device_present().

Therefore, if netdevice is detached, try to runtime-resume the parent
and only return with an error if it's still detached.

Subject: r8169: mark device as not present when in PCI D3

Mark the netdevice as detached whenever we go into PCI D3hot.
This allows to remove some checks e.g. from ethtool ops because
dev_ethtool() checks for netif_device_present() in the beginning.

In this context move waking up the queue out of rtl_reset_work()
because in cases where netif_device_attach() is called afterwards
the queue should be woken up by the latter function only.

Subject: r8169: use RTNL to protect critical sections

Most relevant ops (open, close, ethtool ops) are protected with RTNL
lock by net core. Make sure that such ops can't be interrupted by
e.g. (runtime-)suspending by taking the RTNL lock in suspend ops
and the PCI error handler.

Subject: mlxsw: spectrum: Split handling of pedit mangle by chip type

Certain ACL actions are only available on some Spectrum revisions. In
particular, L4_PORT_ACTION is not available on Spectrum-1. Introduce a
new ops struct intended to hold these differences, mlxsw_sp_rulei_ops.
Prime it with a sole member, act_mangle_field, meant for handling of
pedit mangles.

Create two ops structures, one for Spectrum-1, the other for Spectrum-2
and above. Add callbacks for act_mangle_field and dispatch to the common
handler.

Invoke mlxsw_sp_rulei_ops.act_mangle_field from the field mangler
instead of calling the common handler directly.

Subject: libbpf: Generalize libbpf externs support

Switch existing Kconfig externs to be just one of few possible kinds of more
generic externs. This refactoring is in preparation for ksymbol extern
support, added in the follow up patch. There are no functional changes
intended.

From 1c0c7074fefd769f62dda155e881ca90c9e3e75a Mon Sep 17 00:00:00 2001

Subject: libbpf: Add support for extracting kernel symbol addresses

Add support for another (in addition to existing Kconfig) special kind of
externs in BPF code, kernel symbol externs. Such externs allow BPF code to
"know" kernel symbol address and either use it for comparisons with kernel
data structures (e.g., struct file's f_op pointer, to distinguish different
kinds of file), or, with the help of bpf_probe_user_kernel(), to follow
pointers and read data from global variables. Kernel symbol addresses are
found through /proc/kallsyms, which should be present in the system.

Currently, such kernel symbol variables are typeless: they have to be defined
as `extern const void <symbol>` and the only operation you can do (in C code)
with them is to take its address. Such extern should reside in a special
section '.ksyms'. bpf_helpers.h header provides __ksym macro for this. Strong
vs weak semantics stays the same as with Kconfig externs. If symbol is not
found in /proc/kallsyms, this will be a failure for strong (non-weak) extern,
but will be defaulted to 0 for weak externs.

If the same symbol is defined multiple times in /proc/kallsyms, then it will
be error if any of the associated addresses differs. In that case, address is
ambiguous, so libbpf falls on the side of caution, rather than confusing user
with randomly chosen address.

In the future, once kernel is extended with variables BTF information, such
ksym externs will be supported in a typed version, which will allow BPF
program to read variable's contents directly, similarly to how it's done for
fentry/fexit input arguments.

From a479b8ce4ed1457f814be6f67a8447a9af38f235 Mon Sep 17 00:00:00 2001
From: Andrii Nakryiko <andriin@fb.com>
Date: Fri, 19 Jun 2020 16:16:58 -0700
Subject: tools/bpftool: Move map/prog parsing logic into common

Move functions that parse map and prog by id/tag/name/etc outside of
map.c/prog.c, respectively. These functions are used outside of those files
and are generic enough to be in common. This also makes heavy-weight map.c and
prog.c more decoupled from the rest of bpftool files and facilitates more
lightweight bootstrap bpftool variant.

Subject: tools/bpftool: Minimize bootstrap bpftool

Build minimal "bootstrap mode" bpftool to enable skeleton (and, later,
vmlinux.h generation), instead of building almost complete, but slightly
different (w/o skeletons, etc) bpftool to bootstrap complete bpftool build.

Current approach doesn't scale well (engineering-wise) when adding more BPF
programs to bpftool and other complicated functionality, as it requires
constant adjusting of the code to work in both bootstrapped mode and normal
mode.

So it's better to build only minimal bpftool version that supports only BPF
skeleton code generation and BTF-to-C conversion. Thankfully, this is quite
easy to accomplish due to internal modularity of bpftool commands. This will
also allow to keep adding new functionality to bpftool in general, without the
need to care about bootstrap mode for those new parts of bpftool.

Subject: tools/bpftool: Generalize BPF skeleton support and generate vmlinux.h

Adapt Makefile to support BPF skeleton generation beyond single profiler.bpf.c
case. Also add vmlinux.h generation and switch profiler.bpf.c to use it.

clang-bpf-global-var feature is extended and renamed to clang-bpf-co-re to
check for support of preserve_access_index attribute, which, together with BTF
for global variables, is the minimum requirement for modern BPF programs.

Subject: tools/bpftool: Show info for processes holding BPF map/prog/link/btf
 FDs

Add bpf_iter-based way to find all the processes that hold open FDs against
BPF object (map, prog, link, btf). bpftool always attempts to discover this,
but will silently give up if kernel doesn't yet support bpf_iter BPF programs.
Process name and PID are emitted for each process (task group).

Subject: net: mscc: ocelot: fix encoding destination ports into multicast IPv4
 address

The ocelot hardware designers have made some hacks to support multicast
IPv4 and IPv6 addresses. Normally, the MAC table matches on MAC
addresses and the destination ports are selected through the DEST_IDX
field of the respective MAC table entry. The DEST_IDX points to a Port
Group ID (PGID) which contains the bit mask of ports that frames should
be forwarded to. But there aren't a lot of PGIDs (only 80 or so) and
there are clearly many more IP multicast addresses than that, so it
doesn't scale to use this PGID mechanism, so something else was done.
Since the first portion of the MAC address is known, the hack they did
was to use a single PGID for _flooding_ unknown IPv4 multicast
(PGID_MCIPV4 == 62), but for known IP multicast, embed the destination
ports into the first 3 bytes of the MAC address recorded in the MAC
table.

The VSC7514 datasheet explains it like this:

    3.9.1.5 IPv4 Multicast Entries

    MAC table entries with the ENTRY_TYPE = 2 settings are interpreted
    as IPv4 multicast entries.
    IPv4 multicasts entries match IPv4 frames, which are classified to
    the specified VID, and which have DMAC = 0x01005Exxxxxx, where
    xxxxxx is the lower 24 bits of the MAC address in the entry.
    Instead of a lookup in the destination mask table (PGID), the
    destination set is programmed as part of the entry MAC address. This
    is shown in the following table.

    Table 78: IPv4 Multicast Destination Mask

        Destination Ports            Record Bit Field
        ---------------------------------------------
        Ports 10-0                   MAC[34-24]

    Example: All IPv4 multicast frames in VLAN 12 with MAC 01005E112233 are
    to be forwarded to ports 3, 8, and 9. This is done by inserting the
    following entry in the MAC table entry:
    VALID = 1
    VID = 12
    MAC = 0x000308112233
    ENTRY_TYPE = 2
    DEST_IDX = 0

But this procedure is not at all what's going on in the driver. In fact,
the code that embeds the ports into the MAC address looks like it hasn't
actually been tested. This patch applies the procedure described in the
datasheet.

Since there are many other fixes to be made around multicast forwarding
until it works properly, there is no real reason for this patch to be
backported to stable trees, or considered a real fix of something that
should have worked.

Subject: net: mscc: ocelot: make the NPI port a proper target for FDB and MDB

When used in DSA mode (as seen in Felix), the DEST_IDX in the MAC table
should point to the PGID for the CPU port (PGID_CPU) and not for the
Ethernet port where the CPU queues are redirected to (also known as Node
Processor Interface - NPI).

Because for Felix this distinction shouldn't really matter (from DSA
perspective, the NPI port _is_ the CPU port), make the ocelot library
act upon the CPU port when NPI mode is enabled. This has no effect for
the mscc_ocelot driver for VSC7514, because that does not use NPI (and
ocelot->npi is -1).

Subject: net: mscc: ocelot: introduce macros for iterating over PGIDs

The current iterators are impossible to understand at first glance
without switching back and forth between the definitions and their
actual use in the for loops.

So introduce some convenience names to help readability.

Subject: net: mscc: ocelot: support IPv4, IPv6 and plain Ethernet mdb entries

The current procedure for installing a multicast address is hardcoded
for IPv4. But, in the ocelot hardware, there are 3 different procedures
for IPv4, IPv6 and for regular L2 multicast.

For IPv6 (33-33-xx-xx-xx-xx), it's the same as for IPv4
(01-00-5e-xx-xx-xx), except that the destination port mask is stuffed
into first 2 bytes of the MAC address except into first 3 bytes.

For plain Ethernet multicast, there's no port-in-address stuffing going
on, instead the DEST_IDX (pointer to PGID) is used there, just as for
unicast. So we have to use one of the nonreserved multicast PGIDs that
the hardware has allocated for this purpose.

This patch classifies the type of multicast address based on its first
bytes, then redirects to one of the 3 different hardware procedures.

Note that this gives us a really better way of redirecting PTP frames
sent at 01-1b-19-00-00-00 to the CPU. Previously, Yangbo Lu tried to add
a trapping rule for PTP EtherType but got a lot of pushback:

https://patchwork.ozlabs.org/project/netdev/patch/20190813025214.18601-5-yangbo.lu@nxp.com/

But right now, that isn't needed at all. The application stack (ptp4l)
does this for the PTP multicast addresses it's interested in (which are
configurable, and include 01-1b-19-00-00-00):

	memset(&mreq, 0, sizeof(mreq));
	mreq.mr_ifindex = index;
	mreq.mr_type = PACKET_MR_MULTICAST;
	mreq.mr_alen = MAC_LEN;
	memcpy(mreq.mr_address, addr1, MAC_LEN);

	err1 = setsockopt(fd, SOL_PACKET, PACKET_ADD_MEMBERSHIP, &mreq,
			  sizeof(mreq));

Into the kernel, this translates into a dev_mc_add on the switch network
interfaces, and our drivers know that it means they should translate it
into a host MDB address (make the CPU port be the destination).
Previously, this was broken because all mdb addresses were treated as
IPv4 (which 01-1b-19-00-00-00 obviously is not).

Subject: Bluetooth: add a mutex lock to avoid UAF in do_enale_set

In the case we set or free the global value listen_chan in
different threads, we can encounter the UAF problems because
the method is not protected by any lock, add one to avoid
this bug.

following VRRP protocol states. Using a dedicated rtm_protocol will help
keeping track of it.

Changes in v2:
 - fix tab/space indenting

Subject: bpf: Switch most helper return values from 32-bit int to 64-bit long

Switch most of BPF helper definitions from returning int to long. These
definitions are coming from comments in BPF UAPI header and are used to
generate bpf_helper_defs.h (under libbpf) to be later included and used from
BPF programs.

In actual in-kernel implementation, all the helpers are defined as returning
u64, but due to some historical reasons, most of them are actually defined as
returning int in UAPI (usually, to return 0 on success, and negative value on
error).

This actually causes Clang to quite often generate sub-optimal code, because
compiler believes that return value is 32-bit, and in a lot of cases has to be
up-converted (usually with a pair of 32-bit bit shifts) to 64-bit values,
before they can be used further in BPF code.

Besides just "polluting" the code, these 32-bit shifts quite often cause
problems for cases in which return value matters. This is especially the case
for the family of bpf_probe_read_str() functions. There are few other similar
helpers (e.g., bpf_read_branch_records()), in which return value is used by
BPF program logic to record variable-length data and process it. For such
cases, BPF program logic carefully manages offsets within some array or map to
read variable-length data. For such uses, it's crucial for BPF verifier to
track possible range of register values to prove that all the accesses happen
within given memory bounds. Those extraneous zero-extending bit shifts,
inserted by Clang (and quite often interleaved with other code, which makes
the issues even more challenging and sometimes requires employing extra
per-variable compiler barriers), throws off verifier logic and makes it mark
registers as having unknown variable offset. We'll study this pattern a bit
later below.

Another common pattern is to check return of BPF helper for non-zero state to
detect error conditions and attempt alternative actions in such case. Even in
this simple and straightforward case, this 32-bit vs BPF's native 64-bit mode
quite often leads to sub-optimal and unnecessary extra code. We'll look at
this pattern as well.

Clang's BPF target supports two modes of code generation: ALU32, in which it
is capable of using lower 32-bit parts of registers, and no-ALU32, in which
only full 64-bit registers are being used. ALU32 mode somewhat mitigates the
above described problems, but not in all cases.

This patch switches all the cases in which BPF helpers return 0 or negative
error from returning int to returning long. It is shown below that such change
in definition leads to equivalent or better code. No-ALU32 mode benefits more,
but ALU32 mode doesn't degrade or still gets improved code generation.

Another class of cases switched from int to long are bpf_probe_read_str()-like
helpers, which encode successful case as non-negative values, while still
returning negative value for errors.

In all of such cases, correctness is preserved due to two's complement
encoding of negative values and the fact that all helpers return values with
32-bit absolute value. Two's complement ensures that for negative values
higher 32 bits are all ones and when truncated, leave valid negative 32-bit
value with the same value. Non-negative values have upper 32 bits set to zero
and similarly preserve value when high 32 bits are truncated. This means that
just casting to int/u32 is correct and efficient (and in ALU32 mode doesn't
require any extra shifts).

To minimize the chances of regressions, two code patterns were investigated,
as mentioned above. For both patterns, BPF assembly was analyzed in
ALU32/NO-ALU32 compiler modes, both with current 32-bit int return type and
new 64-bit long return type.

Case 1. Variable-length data reading and concatenation. This is quite
ubiquitous pattern in tracing/monitoring applications, reading data like
process's environment variables, file path, etc. In such case, many pieces of
string-like variable-length data are read into a single big buffer, and at the
end of the process, only a part of array containing actual data is sent to
user-space for further processing. This case is tested in test_varlen.c
selftest (in the next patch). Code flow is roughly as follows:

  void *payload = &sample->payload;
  u64 len;

  len = bpf_probe_read_kernel_str(payload, MAX_SZ1, &source_data1);
  if (len <= MAX_SZ1) {
      payload += len;
      sample->len1 = len;
  }
  len = bpf_probe_read_kernel_str(payload, MAX_SZ2, &source_data2);
  if (len <= MAX_SZ2) {
      payload += len;
      sample->len2 = len;
  }
  /* and so on */
  sample->total_len = payload - &sample->payload;
  /* send over, e.g., perf buffer */

There could be two variations with slightly different code generated: when len
is 64-bit integer and when it is 32-bit integer. Both variations were analysed.
BPF assembly instructions between two successive invocations of
bpf_probe_read_kernel_str() were used to check code regressions. Results are
below, followed by short analysis. Left side is using helpers with int return
type, the right one is after the switch to long.

In ALU32 mode, the variant using 64-bit length variable clearly wins and
avoids unnecessary zero-extension bit shifts. In practice, this is even more
important and good, because BPF code won't need to do extra checks to "prove"
that payload/len are within good bounds.

32-bit len is one instruction longer. Clang decided to do 64-to-32 casting
with two bit shifts, instead of equivalent `w1 = w0` assignment. The former
uses extra register. The latter might potentially lose some range information,
but not for 32-bit value. So in this case, verifier infers that r0 is [0, 256]
after check at 18:, and shifting 32 bits left/right keeps that range intact.
We should probably look into Clang's logic and see why it chooses bitshifts
over sub-register assignments for this.

In NO-ALU32 mode, for the case of 64-bit len variable, Clang generates much
superior code, as expected, eliminating unnecessary bit shifts. For 32-bit
len, code is identical.

So overall, only ALU-32 32-bit len case is more-or-less equivalent and the
difference stems from internal Clang decision, rather than compiler lacking
enough information about types.

Case 2. Let's look at the simpler case of checking return result of BPF helper
for errors. The code is very simple:

  long bla;
  if (bpf_probe_read_kenerl(&bla, sizeof(bla), 0))
      return 1;
  else
      return 0;

ALU32 + CHECK (9 insns)                    ALU32 + CHECK (9 insns)
====================================       ====================================
  0:    r1 = r10                             0:    r1 = r10
  1:    r1 += -8                             1:    r1 += -8
  2:    w2 = 8                               2:    w2 = 8
  3:    r3 = 0                               3:    r3 = 0
  4:    call 113                             4:    call 113
  5:    w1 = w0                              5:    r1 = r0
  6:    w0 = 1                               6:    w0 = 1
  7:    if w1 != 0 goto +1 <LBB2_2>          7:    if r1 != 0 goto +1 <LBB2_2>
  8:    w0 = 0                               8:    w0 = 0
0000000000000048 <LBB2_2>:                 0000000000000048 <LBB2_2>:
  9:    exit                                 9:    exit

Almost identical code, the only difference is the use of full register
assignment (r1 = r0) vs half-registers (w1 = w0) in instruction #5. On 32-bit
architectures, new BPF assembly might be slightly less optimal, in theory. But
one can argue that's not a big issue, given that use of full registers is
still prevalent (e.g., for parameter passing).

Subject: selftests/bpf: Add variable-length data concatenation pattern test

Add selftest that validates variable-length data reading and concatentation
with one big shared data array. This is a common pattern in production use for
monitoring and tracing applications, that potentially can read a lot of data,
but overall read much less. Such pattern allows to determine precisely what

Subject: selftests/bpf: Add variable-length data concat pattern less than test

Extend original variable-length tests with a case to catch a common
existing pattern of testing for < 0 for errors. Note because
verifier also tracks upper bounds and we know it can not be greater
than MAX_LEN here we can skip upper bound check.

In ALU64 enabled compilation converting from long->int return types
in probe helpers results in extra instruction pattern, <<= 32, s >>= 32.
The trade-off is the non-ALU64 case works. If you really care about
every extra insn (XDP case?) then you probably should be using original
int type.

In addition adding a sext insn to bpf might help the verifier in the
general case to avoid these types of tricks.

Subject: tools, bpftool: Correctly evaluate $(BUILD_BPF_SKELS) in Makefile

Currently, if the clang-bpf-co-re feature is not available, the build
fails with e.g.

  CC       prog.o
prog.c:1462:10: fatal error: profiler.skel.h: No such file or directory
 1462 | #include "profiler.skel.h"
      |          ^~~~~~~~~~~~~~~~~

This is due to the fact that the BPFTOOL_WITHOUT_SKELETONS macro is not
defined, despite BUILD_BPF_SKELS not being set. Fix this by correctly
evaluating $(BUILD_BPF_SKELS) when deciding on whether to add
-DBPFTOOL_WITHOUT_SKELETONS to CFLAGS.

Subject: ipv6: fib6: avoid indirect calls from fib6_rule_lookup

It was reported that a considerable amount of cycles were spent on the
expensive indirect calls on fib6_rule_lookup. This patch introduces an
inline helper called pol_route_func that uses the indirect_call_wrappers
to avoid the indirect calls.

This patch saves around 50ns per call.

Performance was measured on the receiver by checking the amount of
syncookies that server was able to generate under a synflood load.

Traffic was generated using trafgen[1] which was pushing around 1Mpps on
a single queue. Receiver was using only one rx queue which help to
create a bottle neck and make the experiment rx-bounded.

These are the syncookies generated over 10s from the different runs:

Without the patch the average is 354263 pkt/s or 2822 ns/pkt and with
the patch the average is 360738 pkt/s or 2772 ns/pkt which gives an
estimate of 50 ns per packet.

Subject: bonding/xfrm: use real_dev instead of slave_dev

Rather than requiring every hw crypto capable NIC driver to do a check for
slave_dev being set, set real_dev in the xfrm layer and xso init time, and
then override it in the bonding driver as needed. Then NIC drivers can
always use real_dev, and at the same time, we eliminate the use of a
variable name that probably shouldn't have been used in the first place,
particularly given recent current events.

Subject: r8169: rename RTL8125 to RTL8125A

Realtek added new members to the RTL8125 chip family, therefore rename
RTL8125 to RTL8125a. Then we use the same chip naming as in the r8125
vendor driver.

Subject: tcp: move ipv6_specific declaration to remove a warning

ipv6_specific should be declared in tcp include files,
not mptcp.

This removes the following warning :
  CHECK   net/ipv6/tcp_ipv6.c

Subject: net: ipv6: Use struct_size() helper and kcalloc()

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes. Also, remove unnecessary
function ipv6_rpl_srh_alloc_size() and replace kzalloc() with kcalloc(),
which has a 2-factor argument form for multiplication.

This code was detected with the help of Coccinelle and, audited and
fixed manually.

Subject: pcnet32: Convert to generic power management

Remove legacy PM callbacks and use generic operations. With legacy code,
drivers were responsible for handling PCI PM operations like
pci_save_state(). In generic code, all these are handled by PCI core.

The generic suspend() and resume() are called at the same point the legacy
ones were called. Thus, it does not affect the normal functioning of the
driver.

Compile-tested only.

Subject: tulip: dmfe: use generic power management

With legacy PM hooks, it was the responsibility of a driver to manage PCI
states and also the device's power state. The generic approach is to let the
PCI core handle the work.

The legacy suspend() and resume() were making use of
pci_read/write_config_dword() to enable/disable wol. Driver editing
configuration registers of a device is not recommended. Thus replace them
all with device_wakeup_enable/disable().

Compile-tested only.

Subject: tulip: windbond-840: use generic power management

With stable support of generic PM callbacks, drivers no longer need to use
legacy .suspend() and .resume() in which they had to maintain PCI states
changes and device's power state themselves.

Earlier, .resume() was invoking pci_enable_device(). Drivers should not
call PCI legacy helper functions, hence, it was removed. This should not
change the behavior of the device as this function is called by PCI core
if somehow pm_ops is not able to bind with the driver, else, required tasks
are managed by the core itself.

Compile-tested only.

Subject: net: phy: Allow mdio buses to auto-probe c45 devices

The mdiobus_scan logic is currently hardcoded to only
work with c22 devices. This works fairly well in most
cases, but its possible that a c45 device doesn't respond
despite being a standard phy. If the parent hardware
is capable, it makes sense to scan for c22 devices before
falling back to c45.

As we want this to reflect the capabilities of the STA,
lets add a field to the mii_bus structure to represent
the capability. That way devices can opt into the extended
scanning. Existing users should continue to default to c22
only scanning as long as they are zero'ing the structure
before use.

Subject: net/fsl: acpize xgmac_mdio

Add ACPI support for xgmac MDIO bus registration while maintaining
the existing DT support.

The function mdiobus_register() inside of_mdiobus_register(), brings
up all the PHYs on the mdio bus and attach them to the bus.

Subject: net/fsl: enable extended scanning in xgmac_mdio

Since we know the xgmac hardware always has a c45
compliant bus, let's try scanning for c22 capable
PHYs first. If we fail to find any, then it will
fall back to c45 automatically.

Subject: selftests/net: plug rxtimestamp test into kselftest framework

Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add
new rxtimestamp.sh wrapper script, so that the test runs isolated
from background traffic in a private network namespace.

Also ignore failures of test case #6 by default. This case verifies
that a receive timestamp is not reported if timestamp reporting is
enabled for a socket, but generation is disabled. Receive timestamp
generation has to be enabled globally, as no associated socket is
known yet. A background process that enables rx timestamp generation
therefore causes a false positive. Ntpd is one example that does.

Add a "--strict" option to cause failure in the event that any test
case fails, including test #6. This is useful for environments that
are known to not have such background processes.

Tested:
make -C tools/testing/selftests TARGETS="net" run_tests

Subject: cxgb4: always sync access when flashing PHY firmware

Access to on-chip memory for flashing PHY firmware must always
be synchronized. So, ensure the callers take on-chip memory lock.

Also fixes following sparse warning:
sge.c:1641:26: warning: context imbalance in 't4_load_phy_fw' -
different lock contexts for basic block

Subject: xfrm: introduce oseq-may-wrap flag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

RFC 4303 in section 3.3.3 suggests to disable anti-replay for manually
distributed ICVs in which case the sender does not need to monitor or
reset the counter. However, the sender still increments the counter and
when it reaches the maximum value, the counter rolls over back to zero.

This patch introduces new extra_flag XFRM_SA_XFLAG_OSEQ_MAY_WRAP which
allows sequence number to cycle in outbound packets if set. This flag is
used only in legacy and bmp code, because esn should not be negotiated
if anti-replay is disabled (see note in 3.3.3 section).

Subject: tools, bpftool: Fix variable shadowing in emit_obj_refs_json()

Building bpftool yields the following complaint:

    pids.c: In function 'emit_obj_refs_json':

      175 | void emit_obj_refs_json(struct obj_refs_table *table, __u32 id, json_writer_t *json_wtr)
          |                                                                 ~~~~~~~~~~~~~~~^~~~~~~~

      141 | extern json_writer_t *json_wtr;
          |                       ^~~~~~~~

Let's rename the variable.

v2:
- Rename the variable instead of calling the global json_wtr directly.

R3 unbounded memory access, use 'var &= const' or 'if (var < const)'

In the C code:
  usize = bpf_get_stack(ctx, raw_data, max_len, BPF_F_USER_STACK);
  if (usize < 0)
          return 0;

  ksize = bpf_get_stack(ctx, raw_data + usize, max_len - usize, 0);
  if (ksize < 0)
          return 0;

We used to have problem with pointer arith in R2.
Now it's a problem with two integers in R3.
'if (usize < 0)' is comparing R1 and makes it [0,800], but R8 stays [-inf,800].
Both registers represent the same 'usize' variable.
Then R9 -= R8 is doing 800 - [-inf, 800]
so the result of "max_len - usize" looks unbounded to the verifier while
it's obvious in C code that "max_len - usize" should be [0, 800].

To workaround the problem convert ksize and usize variables from int to long.

Subject: bpf: Add SO_KEEPALIVE and related options to bpf_setsockopt

This patch adds support of SO_KEEPALIVE flag and TCP related options
to bpf_setsockopt() routine. This is helpful if we want to enable or tune
TCP keepalive for applications which don't do it in the userspace code.

v3:
  - update kernel-doc in uapi (Nikita Vetoshkin <nekto0n@yandex-team.ru>)

v4:
  - update kernel-doc in tools too (Alexei Starovoitov)
  - add test to selftests (Alexei Starovoitov)

Subject: net: phy: add support for a common probe between shared PHYs

Shared PHYs (PHYs in the same hardware package) may have shared
registers and their drivers would usually need to share information.
There is currently a way to have a shared (part of the) init, by using
phy_package_init_once(). This patch extends the logic to share parts of
the probe to allow sharing the initialization of locks or resources
retrieval.

Subject: net: phy: mscc: remove the TR CLK disable magic value

This patch adds a define for the 0x8000 magic value used to perform
enable/disable actions on the "token ring clock". The patch is only
cosmetic.

This patch takes in account the use of the 1588 block in the MACsec
initialization, as a conditional configuration has to be done (when the
1588 block is used).

Subject: net: phy: mscc: 1588 block initialization

This patch adds the first parts of the 1588 support in the MSCC PHY,
with registers definition and the 1588 block initialization.

Those PHYs are distributed in hardware packages containing multiple
times the PHY. The VSC8584 for example is composed of 4 PHYs. With
hardware packages, parts of the logic is usually common and one of the
PHY has to be used for some parts of the initialization. Following this
logic, the 1588 blocks of those PHYs are shared between two PHYs and
accessing the registers has to be done using the "base" PHY of the
group. This is handled thanks to helpers in the PTP code (and locks).
We also need the MDIO bus lock while performing a single read or write
to the 1588 registers as the read/write are composed of multiple MDIO
transactions (and we don't want other threads updating the page).

From 7d272e63e0979d38a6256108adbe462d621c26c5 Mon Sep 17 00:00:00 2001
From: Antoine Tenart <antoine.tenart@bootlin.com>
Date: Tue, 23 Jun 2020 16:30:12 +0200
Subject: net: phy: mscc: timestamping and PHC support

This patch adds support for PHC and timestamping operations for the MSCC
PHY. PTP 1-step and 2-step modes are supported, over Ethernet and UDP.

To get and set the PHC time, a GPIO has to be used and changes are only
retrieved or committed when on a rising edge. The same GPIO is shared by
all PHYs, so the granularity of the lock protecting it has to be
different from the ones protecting the 1588 registers (the VSC8584 PHY
has 2 1588 blocks, and a single load/save pin).

Subject: dt-bindings: net: phy: vsc8531: document the load/save GPIO

A new optional property can be used to reference the load/save GPIO,
used for PTP hardware clock (PHC) operations. This patch documents it in
the binding documentation.

Subject: net: neighbor: add fdb extended attribute

Add an attribute to NDA which will contain all future fdb-specific
attributes in order to avoid polluting the NDA namespace with e.g.
bridge or vxlan specific attributes. The attribute is called
NDA_FDB_EXT_ATTRS and the structure would look like:
 [NDA_FDB_EXT_ATTRS] = {
    [NFEA_xxx]
 }

Subject: net: bridge: add option to allow activity notifications for any fdb
 entries

This patch adds the ability to notify about activity of any entries
(static, permanent or ext_learn). EVPN multihoming peers need it to
properly and efficiently handle mac sync (peer active/locally active).
We add a new NFEA_ACTIVITY_NOTIFY attribute which is used to dump the
current activity state and to control if static entries should be monitored
at all. We use 2 bits - one to activate fdb entry tracking (disabled by
default) and the second to denote that an entry is inactive. We need
the second bit in order to avoid multiple notifications of inactivity.
Obviously this makes no difference for dynamic entries since at the time
of inactivity they get deleted, while the tracked non-dynamic entries get
the inactive bit set and get a notification.

Subject: net: bridge: add a flag to avoid refreshing fdb when changing/adding

When we modify or create a new fdb entry sometimes we want to avoid
refreshing its activity in order to track it properly. One example is
when a mac is received from EVPN multi-homing peer by FRR, which doesn't
want to change local activity accounting. It makes it static and sets a
flag to track its activity.

Subject: net: bpf: Add bpf_seq_afinfo in tcp_iter_state

A new field bpf_seq_afinfo is added to tcp_iter_state
to provide bpf tcp iterator afinfo. There are two
reasons on why we did this.

First, the current way to get afinfo from PDE_DATA
does not work for bpf iterator as its seq_file
inode does not conform to /proc/net/{tcp,tcp6}
inode structures. More specifically, anonymous
bpf iterator will use an anonymous inode which
is shared in the system and we cannot change inode
private data structure at all.

Second, bpf iterator for tcp/tcp6 wants to
traverse all tcp and tcp6 sockets in one pass
and bpf program can control whether they want
to skip one sk_family or not. Having a different
afinfo with family AF_UNSPEC make it easier
to understand in the code.

This patch does not change /proc/net/{tcp,tcp6} behavior
as the bpf_seq_afinfo will be NULL for these two proc files.

Subject: net: bpf: Implement bpf iterator for tcp

The bpf iterator for tcp is implemented. Both tcp4 and tcp6
sockets will be traversed. It is up to bpf program to
filter for tcp4 or tcp6 only, or both families of sockets.

'X' tells kernel to print hex with upper case letters.
/proc/net/tcp{4,6} seq_file show() used this, and
supports it in bpf_seq_printf() helper too.

Subject: bpf: Add bpf_skc_to_tcp6_sock() helper

The helper is used in tracing programs to cast a socket
pointer to a tcp6_sock pointer.
The return value could be NULL if the casting is illegal.

A new helper return type RET_PTR_TO_BTF_ID_OR_NULL is added
so the verifier is able to deduce proper return types for the helper.

Different from the previous BTF_ID based helpers,
the bpf_skc_to_tcp6_sock() argument can be several possible
btf_ids. More specifically, all possible socket data structures
with sock_common appearing in the first in the memory layout.
This patch only added socket types related to tcp and udp.

All possible argument btf_id and return value btf_id
for helper bpf_skc_to_tcp6_sock() are pre-calculcated and
cached. In the future, it is even possible to precompute
these btf_id's at kernel build time.

Subject: bpf: Add bpf_skc_to_{tcp, tcp_timewait, tcp_request}_sock() helpers

Three more helpers are added to cast a sock_common pointer to
an tcp_sock, tcp_timewait_sock or a tcp_request_sock for
tracing programs.

Subject: net: bpf: Add bpf_seq_afinfo in udp_iter_state

Similar to tcp_iter_state, a new field bpf_seq_afinfo is
added to udp_iter_state to provide bpf udp iterator
afinfo.

This does not change /proc/net/{udp, udp6} behavior. But
it enables bpf iterator to avoid get afinfo from PDE_DATA
and iterate through all udp and udp6 sockets in one pass.

Subject: net: bpf: Implement bpf iterator for udp

The bpf iterator for udp is implemented. Both udp4 and udp6
sockets will be traversed. It is up to bpf program to
filter for udp4 or udp6 only, or both families of sockets.

Subject: bpf: Add bpf_skc_to_udp6_sock() helper

The helper is used in tracing programs to cast a socket
pointer to a udp6_sock pointer.
The return value could be NULL if the casting is illegal.

Subject: selftests/bpf: Move newer bpf_iter_* type redefining to a new header
 file

Commit b9f4c01f3e0b ("selftest/bpf: Make bpf_iter selftest
compilable against old vmlinux.h") and Commit dda18a5c0b75
("selftests/bpf: Convert bpf_iter_test_kern{3, 4}.c to define
own bpf_iter_meta") redefined newly introduced types
in bpf programs so the bpf program can still compile
properly with old kernels although loading may fail.

Since this patch set introduced new types and the same
workaround is needed, so let us move the workaround
to a separate header file so they do not clutter
bpf programs.

Subject: selftests/bpf: Refactor some net macros to bpf_tracing_net.h

Refactor bpf_iter_ipv6_route.c and bpf_iter_netlink.c
so net macros, originally from various include/linux header
files, are moved to a new header file
bpf_tracing_net.h. The goal is to improve reuse so
networking tracing programs do not need to
copy these macros every time they use them.

Subject: selftests/bpf: Implement sample udp/udp6 bpf_iter programs

On my VM, I got identical results between /proc/net/udp[6] and
the udp{4,6} bpf iterator.

For udp6:
  $ cat /sys/fs/bpf/p1
    sl  local_address                         remote_address                        st tx_queue rx_queue tr tm->when retrnsmt   uid  timeout inode ref pointer drops

  $ cat /proc/net/udp6
    sl  local_address                         remote_address                        st tx_queue rx_queue tr tm->when retrnsmt   uid  timeout inode ref pointer drops
   1405: 000080FE00000000FF7CC4D0D9EFE4FE:0222 00000000000000000000000000000000:0000 07 00000000:00000000 00:00000000 00000000   193        0 19183 2 0000000029eab111 0

For udp4:
  $ cat /sys/fs/bpf/p4
    sl  local_address rem_address   st tx_queue rx_queue tr tm->when retrnsmt   uid  timeout inode ref pointer drops
   2007: 00000000:1F90 00000000:0000 07 00000000:00000000 00:00000000 00000000     0        0 72540 2 000000004ede477a 0
  $ cat /proc/net/udp
    sl  local_address rem_address   st tx_queue rx_queue tr tm->when retrnsmt   uid  timeout inode ref pointer drops
   2007: 00000000:1F90 00000000:0000 07 00000000:00000000 00:00000000 00000000     0        0 72540 2 000000004ede477a 0

Subject: net: qos: add tc police offloading action with max frame size limit

Current police offloading support the 'burst'' and 'rate_bytes_ps'. Some
hardware own the capability to limit the frame size. If the frame size
larger than the setting, the frame would be dropped. For the police
action itself already accept the 'mtu' parameter in tc command. But not
extend to tc flower offloading. So extend 'mtu' to tc flower offloading.

Base on the tc flower offload police action add max frame size by the
parameter 'mtu'. Tc flower device driver working by the IEEE 802.1Qci
stream filter can implement the max frame size filtering. Add it to the
current hardware tc flower stearm filter driver.

Subject: net: qos: police action add index for tc flower offloading

Hardware device may include more than one police entry. Specifying the
action's index make it possible for several tc filters to share the same
police action when installing the filters.

Propagate this index to device drivers through the flow offload
intermediate representation, so that drivers could share a single
hardware policer between multiple filters.

v1->v2 changes:
- Update the commit message suggest by Ido Schimmel <idosch@idosch.org>

Subject: net: enetc add tc flower offload flow metering policing action

Flow metering entries in IEEE 802.1Qci is an optional function for a
flow filtering module. Flow metering is two rates two buckets and three
color marker to policing the frames. This patch only enable one rate one
bucket and in color blind mode. Flow metering instance are as
specified in the algorithm in MEF 10.3 and in Bandwidth Profile
Parameters. They are:

a) Flow meter instance identifier. An integer value identifying the flow
meter instance. The patch use the police 'index' as thin value.
b) Committed Information Rate (CIR), in bits per second. This patch use
the 'rate_bytes_ps' represent this value.
c) Committed Burst Size (CBS), in octets. This patch use the 'burst'
represent this value.
d) Excess Information Rate (EIR), in bits per second.
e) Excess Burst Size per Bandwidth Profile Flow (EBS), in octets.
And plus some other parameters. This patch set EIR/EBS default disable
and color blind mode.

v1->v2 changes:
- Use div_u64() as division replace the '/' report:

All errors (new ones prefixed by >>):

   ld: drivers/net/ethernet/freescale/enetc/enetc_qos.o: in function `enetc_flowmeter_hw_set':
>> enetc_qos.c:(.text+0x66): undefined reference to `__udivdi3'

Subject: ptp_pch: use generic power management

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

In the case of ptp_pch, after removing PCI helper functions, .suspend()
and .resume() became empty-body functions. Hence, define them NULL and
use dev_pm_ops.

Compile-tested only.

en_tc.h header file declares several TC-specific functions in
CONFIG_MLX5_ESWITCH block even though those functions are only compiled
when CONFIG_MLX5_CLS_ACT is set, which is a recent change. Move them to
proper block.

Subject: net/mlx5e: vxlan: Return bool instead of opaque ptr in port_lookup()

struct mlx5_vxlan_port is not exposed to the outside callers, it is
redundant to return a pointer to it from mlx5_vxlan_port_lookup(), to be
only used as a boolean, so just return a boolean.

Subject: net: phylink: add phylink_speed_(up|down) interface

Add an interface for the phy_speed_(up|down) functions when a driver
makes use of phylink. These pass the call through to phylib when we
have a normal PHY attached (i.o.w., not a PHY on a SFP module.)

Subject: dt-bindings: net: Add tx and rx internal delays

tx-internal-delays and rx-internal-delays are a common setting for RGMII
capable devices.

These properties are used when the phy-mode or phy-controller is set to
rgmii-id, rgmii-rxid or rgmii-txid.  These modes indicate to the
controller that the PHY will add the internal delay for the connection.

Subject: net: phy: Add a helper to return the index for of the internal delay

Add a helper function that will return the index in the array for the
passed in internal delay value.  The helper requires the array, size and
delay value.

The helper will then return the index for the exact match or return the
index for the index to the closest smaller value.

Subject: net: phy: DP83822: Add setting the fixed internal delay

The DP83822 can be configured to use the RGMII interface. There are
independent fixed 3.5ns clock shift (aka internal delay) for the TX and RX
paths. This allow either one to be set if the MII interface is RGMII and
the value is set in the firmware node.

Subject: net: phy: mscc: fix a possible double unlock

On vsc8584_ptp_init failure we jump to the 'err' label, which unlocks
the MDIO bus lock. But vsc8584_ptp_init isn't called with the MDIO bus
lock taken, which could result in a double unlock. Fix this.

Subject: net: phy: mscc: ptp: fix a smatch error

The following error was reported by smatch:
vsc85xx_ts_read_csr() error: uninitialized symbol 'blk_hw'.

In practice this is very unlikely, as all the block identifiers given to
this functions are handled and described in an enum. The smatch error is
fixed by doing what is already done in vsc85xx_ts_write_csr: using the
"PROCESSOR" block by default.

Subject: net: phy: mscc: do not access the MDIO bus lock directly

This patch improves the MSCC driver by using the provided
phy_lock_mdio_bus and phy_unlock_mdio_bus helpers instead of locking and
unlocking the MDIO bus lock directly. The patch is only cosmetic but
should improve maintenance and consistency.

Subject: net: phy: mscc: restore the base page in vsc8514/8584_config_init

In the vsc8584_config_init and vsc8514_config_init, the base page is set
to 'GPIO', configuration is done, and the page is never explicitly
restored to the standard page. No bug was triggered as it turns out
helpers called in those config_init functions do modify the base page,
and set it back to standard. But that is dangerous and any modification
to those functions would introduce bugs. This patch fixes this, to
improve maintenance, by restoring the base page to 'standard' once
'GPIO' accesses are completed.

In the middle of vsc8584_config_init and vsc8514_config_init, the page
is set to 'standard'. This is the default value, and the page isn't set
to another value before. Those pages configuration can be safely
removed.

Change tin mapping on diffserv3, 4 & 8 for LE PHB support, in essence
making LE a member of the Bulk tin.

Bulk has the least priority and minimum of 1/16th total bandwidth in the
face of higher priority traffic.

NB: Diffserv 3 & 4 swap tin 0 & 1 priorities from the default order as

Subject: i40e: make PF wait reset loop reliable

Use jiffies to limit max waiting time for PF reset to succeed.
Previous wait loop was unreliable. It required unreasonably long time
to wait for PF reset after reboot when NIC was about to enter
recovery mode

Subject: i40e: detect and log info about pre-recovery mode

Detect and log information about pre-recovery mode when firmware
transitions to a recovery mode.
When a firmware transitions to a recovery mode it stores a number
of unexpected EMP resets in one of its registers. The number of EMP
resets ranging from 0x21 to 0x2A indicates that FW transitions
to recovery mode. Use these values to emit log entry about transition
process. Previously the pre-recovery mode may not have been detected
and there was no log entry when NIC was in pre-recovery mode.

Subject: i40e: Add a check to see if MFS is set

A customer was chain-booting to provision his systems and one of the
steps was setting MFS. MFS isn't cleared by normal warm reboots
(clearing requires a GLOBR) and there was no indication of why Jumbo
Frame receives were failing.

Add a warning if MFS is set to anything lower than the default.

Subject: net/intel: remove driver versions from Intel drivers

As with other networking drivers, remove the unnecessary driver version
from the Intel drivers. The ethtool driver information and module version
will then report the kernel version instead.

For ixgbe, i40e and ice drivers, the driver passes the driver version to
the firmware to confirm that we are up and running.  So we now pass the
value of UTS_RELEASE to the firmware.  This adminq call is required per
the HAS document.  The Device then sends an indication to the BMC that the
PF driver is present. This is done using Host NC Driver Status Indication
in NC-SI Get Link command or via the Host Network Controller Driver Status
Change AEN.

What the BMC may do with this information is implementation-dependent, but
this is a standard NC-SI 1.1 command we honor per the HAS.

Subject: i40e: Remove scheduling while atomic possibility

In some occasions task held spinlock (mac_filter_hash_lock),
while being rescheduled due to admin queue mutex_lock.  The struct
i40e_spinlock asq_spinlock, which later expands to struct mutex
spinlock.  Moved i40e_aq_set_vsi_multicast_promiscuous(),
i40e_aq_set_vsi_unicast_promiscuous(),
i40e_aq_set_vsi_mc_promisc_on_vlan(), and
i40e_aq_set_vsi_uc_promisc_on_vlan() outside of atomic context.  Without
this patch there is a race condition, which might result in scheduling
while in atomic context.  The race condition is between the thread, which
holds mac_filter_hash_lock, while trying to acquire an admin queue mutex
and a thread, which already has said admin queue mutex. The thread, which
holds spinlock, fails to acquire the mutex, which causes this thread to
sleep.

Subject: wilc1000: move wilc driver out of staging

WILC1000 is an IEEE 802.11 b/g/n IoT link controller module. The
WILC1000 connects to Microchip AVR/SMART MCUs, SMART MPUs, and other
processors with minimal resource requirements with a simple
SPI/SDIO-to-Wi-Fi interface.

WILC1000 driver has been part of staging for few years. With
contributions from the community, it has improved significantly. Full
driver review has helped in achieving the current state.
The details for those reviews are captured in 1 & 2.

+	  Add support for the Atmel WILC1000 802.11 b/g/n SoC.
+	  This provides Wi-FI over an SDIO or SPI interface, and
+	  is usually found in IoT devices.
+
+	  This module only support IEEE 802.11n WiFi.

+	help
+	  This module adds support for the SDIO interface of adapters using
+	  WILC1000 chipset. The Atmel WILC1000 SDIO is a full speed interface.
+	  It meets SDIO card specification version 2.0. The interface supports
+	  the 1-bit/4-bit SD transfer mode at the clock range of 0-50 MHz.
+	  The host can use this interface to read and write from any register
+	  within the chip as well as configure the WILC1000 for data DMA.
+	  To use this interface, pin9 (SDIO_SPI_CFG) must be grounded. Select
+	  this if your platform is using the SDIO bus.

+	  This module adds support for the SPI interface of adapters using
+	  WILC1000 chipset. The Atmel WILC1000 has a Serial Peripheral
+	  Interface (SPI) that operates as a SPI slave. This SPI interface can
+	  be used for control and for serial I/O of 802.11 data. The SPI is a
+	  full-duplex slave synchronous serial interface that is available
+	  immediately following reset when pin 9 (SDIO_SPI_CFG) is tied to
+	  VDDIO. Select this if your platform is using the SPI bus.

+	  This option enables out-of-band interrupt support for the WILC1000
+	  chipset. This OOB interrupt is intended to provide a faster interrupt
+	  mechanism for SDIO host controllers that don't support SDIO interrupt.
+	  Select this option If the SDIO host controller in your platform
+	  doesn't support SDIO time devision interrupt.

From 3bda14d09dc5789a895ab02b7dcfcec19b0a65b3 Mon Sep 17 00:00:00 2001
From: Linus Lüssing <linus.luessing@c0d3.blue>
Date: Mon, 1 Jun 2020 22:35:22 +0200
Subject: batman-adv: Introduce a configurable per interface hop penalty
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In some setups multiple hard interfaces with similar link qualities
or throughput values are available. But people have expressed the desire
to consider one of them as a backup only.

Some creative solutions are currently in use: Such people are
configuring multiple batman-adv mesh/soft interfaces, wire them
together with some veth pairs and then tune the hop penalty to achieve
an effect similar to a tunable per interface hop penalty.

This patch introduces a new, configurable, per hard interface hop penalty
to simplify such setups.

Subject: bnx2x: use generic power management

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

The driver was also calling bnx2x_set_power_state() to set the power state
of the device by changing the device's registers' value. It is no more
needed.

Compile-tested only.

Subject: bonding: Remove extraneous parentheses in bond_setup

Clang warns:

drivers/net/bonding/bond_main.c:4657:23: warning: equality comparison
with extraneous parentheses [-Wparentheses-equality]
        if ((BOND_MODE(bond) == BOND_MODE_ACTIVEBACKUP))
             ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~

drivers/net/bonding/bond_main.c:4681:23: warning: equality comparison
with extraneous parentheses [-Wparentheses-equality]
        if ((BOND_MODE(bond) == BOND_MODE_ACTIVEBACKUP))
             ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~

This warning occurs when a comparision has two sets of parentheses,
which is usually the convention for doing an assignment within an
if statement. Since equality comparisons do not need a second set of
parentheses, remove them to fix the warning.

Subject: net: mvneta: speed down the PHY, if WoL used, to save energy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some PHYs connected to this ethernet hardware support the WoL feature.
But when WoL is enabled and the machine is powered off, the PHY remains
waiting for a magic packet at max speed (i.e. 1Gbps), which is a waste of
energy.

Slow down the PHY speed before stopping the ethernet if WoL is enabled,
and save some energy while the machine is powered off or sleeping.

Tested using an Armada 370 based board (LS421DE) equipped with a Marvell
88E1518 PHY.

Subject: net: mdio: add a forward declaration for reset_control to mdio.h

This header refers to struct reset_control but doesn't include any reset
header. The structure definition is probably somehow indirectly pulled in
since no warnings are reported but for the sake of correctness add the
forward declaration for struct reset_control.

Subject: net: phy: reset the PHY even if probe() is not implemented

Currently we only call phy_device_reset() if the PHY driver implements
the probe() callback. This is not mandatory and many drivers (e.g.
realtek) don't need probe() for most devices but still can have reset
GPIOs defined. There's no reason to depend on the presence of probe()
here so pull the reset code out of the if clause.

Subject: net: phy: mdio: reset MDIO devices even if probe() is not implemented

Similarily to PHY drivers - there's no reason to require probe() to be
implemented in order to call mdio_device_reset(). MDIO devices can have
resets defined without needing to do anything in probe().

Subject: docs: networking: reorganize driver documentation again

Organize driver documentation by device type. Most documents
have fairly verbose yet uninformative names, so let users
first select a well defined device type, and then search for
a particular driver.

While at it rename the section from Vendor drivers to
Hardware drivers. This seems more accurate, besides people
sometimes refer to out-of-tree drivers as vendor drivers.

-Linux and the 3Com EtherLink III Series Ethercards (driver v1.18c and higher)
-=============================================================================
-
-This file contains the instructions and caveats for v1.18c and higher versions
-of the 3c509 driver. You should not use the driver without reading this file.
-
-release 1.0
-
-28 February 2002

-
-Introduction
-============
-
-The following are notes and information on using the 3Com EtherLink III series
-ethercards in Linux. These cards are commonly known by the most widely-used
-card's 3Com model number, 3c509. They are all 10mb/s ISA-bus cards and shouldn't
-be (but sometimes are) confused with the similarly-numbered PCI-bus "3c905"
-(aka "Vortex" or "Boomerang") series.  Kernel support for the 3c509 family is
-provided by the module 3c509.c, which has code to support all of the following
-models:
-
- - 3c509 (original ISA card)
- - 3c509B (later revision of the ISA card; supports full-duplex)
- - 3c589 (PCMCIA)
- - 3c589B (later revision of the 3c589; supports full-duplex)
- - 3c579 (EISA)
-
-Large portions of this documentation were heavily borrowed from the guide
-written the original author of the 3c509 driver, Donald Becker. The master
-copy of that document, which contains notes on older versions of the driver,
-currently resides on Scyld web server: http://www.scyld.com/.
-
-
-Special Driver Features
-=======================
-
-Overriding card settings
-
-The driver allows boot- or load-time overriding of the card's detected IOADDR,
-IRQ, and transceiver settings, although this capability shouldn't generally be
-needed except to enable full-duplex mode (see below). An example of the syntax
-for LILO parameters for doing this::
-
-    ether=10,0x310,3,0x3c509,eth0
-
-This configures the first found 3c509 card for IRQ 10, base I/O 0x310, and
-transceiver type 3 (10base2). The flag "0x3c509" must be set to avoid conflicts
-with other card types when overriding the I/O address. When the driver is
-loaded as a module, only the IRQ may be overridden. For example,
-setting two cards to IRQ10 and IRQ11 is done by using the irq module
-option::
-
-   options 3c509 irq=10,11
-
-
-Full-duplex mode
-================
-
-The v1.18c driver added support for the 3c509B's full-duplex capabilities.
-In order to enable and successfully use full-duplex mode, three conditions
-must be met:
-
-(a) You must have a Etherlink III card model whose hardware supports full-
-duplex operations. Currently, the only members of the 3c509 family that are
-positively known to support full-duplex are the 3c509B (ISA bus) and 3c589B
-(PCMCIA) cards. Cards without the "B" model designation do *not* support
-full-duplex mode; these include the original 3c509 (no "B"), the original
-3c589, the 3c529 (MCA bus), and the 3c579 (EISA bus).
-
-(b) You must be using your card's 10baseT transceiver (i.e., the RJ-45
-connector), not its AUI (thick-net) or 10base2 (thin-net/coax) interfaces.
-AUI and 10base2 network cabling is physically incapable of full-duplex
-operation.
-
-(c) Most importantly, your 3c509B must be connected to a link partner that is
-itself full-duplex capable. This is almost certainly one of two things: a full-
-duplex-capable  Ethernet switch (*not* a hub), or a full-duplex-capable NIC on
-another system that's connected directly to the 3c509B via a crossover cable.
-
-Full-duplex mode can be enabled using 'ethtool'.
-
-.. warning::
-
-  Extremely important caution concerning full-duplex mode
-
-  Understand that the 3c509B's hardware's full-duplex support is much more
-  limited than that provide by more modern network interface cards. Although
-  at the physical layer of the network it fully supports full-duplex operation,
-  the card was designed before the current Ethernet auto-negotiation (N-way)
-  spec was written. This means that the 3c509B family ***cannot and will not
-  auto-negotiate a full-duplex connection with its link partner under any
-  circumstances, no matter how it is initialized***. If the full-duplex mode
-  of the 3c509B is enabled, its link partner will very likely need to be
-  independently _forced_ into full-duplex mode as well; otherwise various nasty
-  failures will occur - at the very least, you'll see massive numbers of packet
-  collisions. This is one of very rare circumstances where disabling auto-
-  negotiation and forcing the duplex mode of a network interface card or switch
-  would ever be necessary or desirable.
-
-
-Available Transceiver Types
-===========================
-
-For versions of the driver v1.18c and above, the available transceiver types are:
-
-== =========================================================================
-0  transceiver type from EEPROM config (normally 10baseT); force half-duplex
-1  AUI (thick-net / DB15 connector)
-2  (undefined)
-3  10base2 (thin-net == coax / BNC connector)
-4  10baseT (RJ-45 connector); force half-duplex mode
-8  transceiver type and duplex mode taken from card's EEPROM config settings
-12 10baseT (RJ-45 connector); force full-duplex mode
-== =========================================================================
-
-Prior to driver version 1.18c, only transceiver codes 0-4 were supported. Note
-that the new transceiver codes 8 and 12 are the *only* ones that will enable
-full-duplex mode, no matter what the card's detected EEPROM settings might be.
-This insured that merely upgrading the driver from an earlier version would
-never automatically enable full-duplex mode in an existing installation;
-it must always be explicitly enabled via one of these code in order to be
-activated.
-
-The transceiver type can be changed using 'ethtool'.
-
-
-Interpretation of error messages and common problems
-----------------------------------------------------
-
-Error Messages
-^^^^^^^^^^^^^^
-
-eth0: Infinite loop in interrupt, status 2011.
-These are "mostly harmless" message indicating that the driver had too much
-work during that interrupt cycle. With a status of 0x2011 you are receiving
-packets faster than they can be removed from the card. This should be rare
-or impossible in normal operation. Possible causes of this error report are:
-
-   - a "green" mode enabled that slows the processor down when there is no
-     keyboard activity.
-
-   - some other device or device driver hogging the bus or disabling interrupts.
-     Check /proc/interrupts for excessive interrupt counts. The timer tick
-     interrupt should always be incrementing faster than the others.
-
-No received packets
-^^^^^^^^^^^^^^^^^^^
-
-If a 3c509, 3c562 or 3c589 can successfully transmit packets, but never
-receives packets (as reported by /proc/net/dev or 'ifconfig') you likely
-have an interrupt line problem. Check /proc/interrupts to verify that the
-card is actually generating interrupts. If the interrupt count is not
-increasing you likely have a physical conflict with two devices trying to
-use the same ISA IRQ line. The common conflict is with a sound card on IRQ10
-or IRQ5, and the easiest solution is to move the 3c509 to a different
-interrupt line. If the device is receiving packets but 'ping' doesn't work,
-you have a routing problem.
-
-Tx Carrier Errors Reported in /proc/net/dev
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-
-If an EtherLink III appears to transmit packets, but the "Tx carrier errors"
-field in /proc/net/dev increments as quickly as the Tx packet count, you
-likely have an unterminated network or the incorrect media transceiver selected.
-
-3c509B card is not detected on machines with an ISA PnP BIOS.
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-While the updated driver works with most PnP BIOS programs, it does not work
-with all. This can be fixed by disabling PnP support using the 3Com-supplied
-setup program.
-
-3c509 card is not detected on overclocked machines
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Increase the delay time in id_read_eeprom() from the current value, 500,
-to an absurdly high value, such as 5000.
-
-
-Decoding Status and Error Messages
-----------------------------------
-
-
-The bits in the main status register are:
-
-=====	======================================
-value 	description
-=====	======================================
-0x01 	Interrupt latch
-0x02 	Tx overrun, or Rx underrun
-0x04 	Tx complete
-0x08 	Tx FIFO room available
-0x10 	A complete Rx packet has arrived
-0x20 	A Rx packet has started to arrive
-0x40 	The driver has requested an interrupt
-0x80 	Statistics counter nearly full
-=====	======================================
-
-The bits in the transmit (Tx) status word are:
-
-=====	============================================
-value	description
-=====	============================================
-0x02	Out-of-window collision.
-0x04	Status stack overflow (normally impossible).
-0x08	16 collisions.
-0x10	Tx underrun (not enough PCI bus bandwidth).
-0x20	Tx jabber.
-0x40	Tx interrupt requested.
-0x80	Status is valid (this should always be set).
-=====	============================================
-
-
-When a transmit error occurs the driver produces a status message such as::
-
-   eth0: Transmit error, Tx status register 82
-
-The two values typically seen here are:
-
-0x82
-^^^^
-
-Out of window collision. This typically occurs when some other Ethernet
-host is incorrectly set to full duplex on a half duplex network.
-
-0x88
-^^^^
-
-16 collisions. This typically occurs when the network is exceptionally busy
-or when another host doesn't correctly back off after a collision. If this
-error is mixed with 0x82 errors it is the result of a host incorrectly set
-to full duplex (see above).
-
-Both of these errors are the result of network problems that should be
-corrected. They do not represent driver malfunction.

-Module parameters
-=================
-
-There are several parameters which may be provided to the driver when
-its module is loaded.  These are usually placed in ``/etc/modprobe.d/*.conf``
-configuration files.  Example::
-
-    options 3c59x debug=3 rx_copybreak=300
-
-If you are using the PCMCIA tools (cardmgr) then the options may be
-placed in /etc/pcmcia/config.opts::
-
-    module "3c59x" opts "debug=3 rx_copybreak=300"
-
-
-The supported parameters are:
-
-debug=N
-
-  Where N is a number from 0 to 7.  Anything above 3 produces a lot
-  of output in your system logs.  debug=1 is default.
-
-options=N1,N2,N3,...
-
-  Each number in the list provides an option to the corresponding
-  network card.  So if you have two 3c905's and you wish to provide
-  them with option 0x204 you would use::
-
-    options=0x204,0x204
-
-  The individual options are composed of a number of bitfields which
-  have the following meanings:
-
-  Possible media type settings
-
-	==	=================================
-	0	10baseT
-	1	10Mbs AUI
-	2	undefined
-	3	10base2 (BNC)
-	4	100base-TX
-	5	100base-FX
-	6	MII (Media Independent Interface)
-	7	Use default setting from EEPROM
-	8       Autonegotiate
-	9       External MII
-	10      Use default setting from EEPROM
-	==	=================================
-
-  When generating a value for the 'options' setting, the above media
-  selection values may be OR'ed (or added to) the following:
-
-  ======  =============================================
-  0x8000  Set driver debugging level to 7
-  0x4000  Set driver debugging level to 2
-  0x0400  Enable Wake-on-LAN
-  0x0200  Force full duplex mode.
-  0x0010  Bus-master enable bit (Old Vortex cards only)
-  ======  =============================================
-
-  For example::
-
-    insmod 3c59x options=0x204
-
-  will force full-duplex 100base-TX, rather than allowing the usual
-  autonegotiation.
-
-global_options=N
-
-  Sets the ``options`` parameter for all 3c59x NICs in the machine.
-  Entries in the ``options`` array above will override any setting of
-  this.
-
-full_duplex=N1,N2,N3...
-
-  Similar to bit 9 of 'options'.  Forces the corresponding card into
-  full-duplex mode.  Please use this in preference to the ``options``
-  parameter.
-
-  In fact, please don't use this at all! You're better off getting
-  autonegotiation working properly.
-
-global_full_duplex=N1
-
-  Sets full duplex mode for all 3c59x NICs in the machine.  Entries
-  in the ``full_duplex`` array above will override any setting of this.
-
-flow_ctrl=N1,N2,N3...
-
-  Use 802.3x MAC-layer flow control.  The 3com cards only support the
-  PAUSE command, which means that they will stop sending packets for a
-  short period if they receive a PAUSE frame from the link partner.
-
-  The driver only allows flow control on a link which is operating in
-  full duplex mode.
-
-  This feature does not appear to work on the 3c905 - only 3c905B and
-  3c905C have been tested.
-
-  The 3com cards appear to only respond to PAUSE frames which are
-  sent to the reserved destination address of 01:80:c2:00:00:01.  They
-  do not honour PAUSE frames which are sent to the station MAC address.
-
-rx_copybreak=M
-
-  The driver preallocates 32 full-sized (1536 byte) network buffers
-  for receiving.  When a packet arrives, the driver has to decide
-  whether to leave the packet in its full-sized buffer, or to allocate
-  a smaller buffer and copy the packet across into it.
-
-  This is a speed/space tradeoff.
-
-  The value of rx_copybreak is used to decide when to make the copy.
-  If the packet size is less than rx_copybreak, the packet is copied.
-  The default value for rx_copybreak is 200 bytes.
-
-max_interrupt_work=N
-
-  The driver's interrupt service routine can handle many receive and
-  transmit packets in a single invocation.  It does this in a loop.
-  The value of max_interrupt_work governs how many times the interrupt
-  service routine will loop.  The default value is 32 loops.  If this
-  is exceeded the interrupt service routine gives up and generates a
-  warning message "eth0: Too much work in interrupt".
-
-hw_checksums=N1,N2,N3,...
-
-  Recent 3com NICs are able to generate IPv4, TCP and UDP checksums
-  in hardware.  Linux has used the Rx checksumming for a long time.
-  The "zero copy" patch which is planned for the 2.4 kernel series
-  allows you to make use of the NIC's DMA scatter/gather and transmit
-  checksumming as well.
-
-  The driver is set up so that, when the zerocopy patch is applied,
-  all Tornado and Cyclone devices will use S/G and Tx checksums.
-
-  This module parameter has been provided so you can override this
-  decision.  If you think that Tx checksums are causing a problem, you
-  may disable the feature with ``hw_checksums=0``.
-
-  If you think your NIC should be performing Tx checksumming and the
-  driver isn't enabling it, you can force the use of hardware Tx
-  checksumming with ``hw_checksums=1``.
-
-  The driver drops a message in the logfiles to indicate whether or
-  not it is using hardware scatter/gather and hardware Tx checksums.
-
-  Scatter/gather and hardware checksums provide considerable
-  performance improvement for the sendfile() system call, but a small
-  decrease in throughput for send().  There is no effect upon receive
-  efficiency.
-
-compaq_ioaddr=N,
-compaq_irq=N,
-compaq_device_id=N
-
-  "Variables to work-around the Compaq PCI BIOS32 problem"....
-
-watchdog=N
-
-  Sets the time duration (in milliseconds) after which the kernel
-  decides that the transmitter has become stuck and needs to be reset.
-  This is mainly for debugging purposes, although it may be advantageous
-  to increase this value on LANs which have very high collision rates.
-  The default value is 5000 (5.0 seconds).
-
-enable_wol=N1,N2,N3,...
-
-  Enable Wake-on-LAN support for the relevant interface.  Donald
-  Becker's ``ether-wake`` application may be used to wake suspended
-  machines.
-
-  Also enables the NIC's power management support.
-
-global_enable_wol=N
-
-  Sets enable_wol mode for all 3c59x NICs in the machine.  Entries in
-  the ``enable_wol`` array above will override any setting of this.
-
-Media selection
----------------
-
-A number of the older NICs such as the 3c590 and 3c900 series have
-10base2 and AUI interfaces.
-
-Prior to January, 2001 this driver would autoeselect the 10base2 or AUI
-port if it didn't detect activity on the 10baseT port.  It would then
-get stuck on the 10base2 port and a driver reload was necessary to
-switch back to 10baseT.  This behaviour could not be prevented with a
-module option override.
-
-Later (current) versions of the driver _do_ support locking of the
-media type.  So if you load the driver module with
-
-	modprobe 3c59x options=0
-
-it will permanently select the 10baseT port.  Automatic selection of
-other media types does not occur.
-
-
-Transmit error, Tx status register 82
--------------------------------------
-
-This is a common error which is almost always caused by another host on
-the same network being in full-duplex mode, while this host is in
-half-duplex mode.  You need to find that other host and make it run in
-half-duplex mode or fix this host to run in full-duplex mode.
-
-As a last resort, you can force the 3c59x driver into full-duplex mode
-with
-
-	options 3c59x full_duplex=1
-
-but this has to be viewed as a workaround for broken network gear and
-should only really be used for equipment which cannot autonegotiate.

-Autonegotiation notes
----------------------
-
-  The driver uses a one-minute heartbeat for adapting to changes in
-  the external LAN environment if link is up and 5 seconds if link is down.
-  This means that when, for example, a machine is unplugged from a hubbed
-  10baseT LAN plugged into a  switched 100baseT LAN, the throughput
-  will be quite dreadful for up to sixty seconds.  Be patient.
-
-  Cisco interoperability note from Walter Wong <wcw+@CMU.EDU>:
-
-  On a side note, adding HAS_NWAY seems to share a problem with the
-  Cisco 6509 switch.  Specifically, you need to change the spanning
-  tree parameter for the port the machine is plugged into to 'portfast'
-  mode.  Otherwise, the negotiation fails.  This has been an issue
-  we've noticed for a while but haven't had the time to track down.
-
-  Cisco switches    (Jeff Busch <jbusch@deja.com>)
-
-    My "standard config" for ports to which PC's/servers connect directly::
-
-	interface FastEthernet0/N
-	description machinename
-	load-interval 30
-	spanning-tree portfast
-
-    If autonegotiation is a problem, you may need to specify "speed
-    100" and "duplex full" as well (or "speed 10" and "duplex half").
-
-    WARNING: DO NOT hook up hubs/switches/bridges to these
-    specially-configured ports! The switch will become very confused.
-
-
-Reporting and diagnosing problems
----------------------------------
-
-Maintainers find that accurate and complete problem reports are
-invaluable in resolving driver problems.  We are frequently not able to
-reproduce problems and must rely on your patience and efforts to get to
-the bottom of the problem.
-
-If you believe you have a driver problem here are some of the
-steps you should take:
-
-- Is it really a driver problem?
-
-   Eliminate some variables: try different cards, different
-   computers, different cables, different ports on the switch/hub,
-   different versions of the kernel or of the driver, etc.
-
-- OK, it's a driver problem.
-
-   You need to generate a report.  Typically this is an email to the
-   maintainer and/or netdev@vger.kernel.org.  The maintainer's
-   email address will be in the driver source or in the MAINTAINERS file.
-
-- The contents of your report will vary a lot depending upon the
-  problem.  If it's a kernel crash then you should refer to the
-  admin-guide/reporting-bugs.rst file.
-
-  But for most problems it is useful to provide the following:
-
-   - Kernel version, driver version
-
-   - A copy of the banner message which the driver generates when
-     it is initialised.  For example:
-
-     eth0: 3Com PCI 3c905C Tornado at 0xa400,  00:50:da:6a:88:f0, IRQ 19
-     8K byte-wide RAM 5:3 Rx:Tx split, autoselect/Autonegotiate interface.
-     MII transceiver found at address 24, status 782d.
-     Enabling bus-master transmits and whole-frame receives.
-
-     NOTE: You must provide the ``debug=2`` modprobe option to generate
-     a full detection message.  Please do this::
-
-	modprobe 3c59x debug=2
-
-   - If it is a PCI device, the relevant output from 'lspci -vx', eg::
-
-       00:09.0 Ethernet controller: 3Com Corporation 3c905C-TX [Fast Etherlink] (rev 74)
-	       Subsystem: 3Com Corporation: Unknown device 9200
-	       Flags: bus master, medium devsel, latency 32, IRQ 19
-	       I/O ports at a400 [size=128]
-	       Memory at db000000 (32-bit, non-prefetchable) [size=128]
-	       Expansion ROM at <unassigned> [disabled] [size=128K]
-	       Capabilities: [dc] Power Management version 2
-       00: b7 10 00 92 07 00 10 02 74 00 00 02 08 20 00 00
-       10: 01 a4 00 00 00 00 00 db 00 00 00 00 00 00 00 00
-       20: 00 00 00 00 00 00 00 00 00 00 00 00 b7 10 00 10
-       30: 00 00 00 00 dc 00 00 00 00 00 00 00 05 01 0a 0a
-
-   - A description of the environment: 10baseT? 100baseT?
-     full/half duplex? switched or hubbed?
-
-   - Any additional module parameters which you may be providing to the driver.
-
-   - Any kernel logs which are produced.  The more the merrier.
-     If this is a large file and you are sending your report to a
-     mailing list, mention that you have the logfile, but don't send
-     it.  If you're reporting direct to the maintainer then just send
-     it.
-
-     To ensure that all kernel logs are available, add the
-     following line to /etc/syslog.conf::
-
-	 kern.* /var/log/messages
-
-     Then restart syslogd with::
-
-	 /etc/rc.d/init.d/syslog restart
-
-     (The above may vary, depending upon which Linux distribution you use).
-
-    - If your problem is reproducible then that's great.  Try the
-      following:
-
-      1) Increase the debug level.  Usually this is done via:
-
-	 a) modprobe driver debug=7
-	 b) In /etc/modprobe.d/driver.conf:
-	    options driver debug=7
-
-      2) Recreate the problem with the higher debug level,
-	 send all logs to the maintainer.
-
-      3) Download you card's diagnostic tool from Donald
-	 Becker's website <http://www.scyld.com/ethercard_diag.html>.
-	 Download mii-diag.c as well.  Build these.
-
-	 a) Run 'vortex-diag -aaee' and 'mii-diag -v' when the card is
-	    working correctly.  Save the output.
-
-	 b) Run the above commands when the card is malfunctioning.  Send
-	    both sets of output.
-
-Finally, please be patient and be prepared to do some work.  You may
-end up working on this problem for a week or more as the maintainer
-asks more questions, asks for more tests, asks for patches to be
-applied, etc.  At the end of it all, the problem may even remain
-unresolved.

-============================================================
-Linux kernel driver for Elastic Network Adapter (ENA) family
-============================================================
-
-Overview
-========
-
-ENA is a networking interface designed to make good use of modern CPU
-features and system architectures.
-
-The ENA device exposes a lightweight management interface with a
-minimal set of memory mapped registers and extendable command set
-through an Admin Queue.
-
-The driver supports a range of ENA devices, is link-speed independent
-(i.e., the same driver is used for 10GbE, 25GbE, 40GbE, etc.), and has
-a negotiated and extendable feature set.
-
-Some ENA devices support SR-IOV. This driver is used for both the
-SR-IOV Physical Function (PF) and Virtual Function (VF) devices.
-
-ENA devices enable high speed and low overhead network traffic
-processing by providing multiple Tx/Rx queue pairs (the maximum number
-is advertised by the device via the Admin Queue), a dedicated MSI-X
-interrupt vector per Tx/Rx queue pair, adaptive interrupt moderation,
-and CPU cacheline optimized data placement.
-
-The ENA driver supports industry standard TCP/IP offload features such
-as checksum offload and TCP transmit segmentation offload (TSO).
-Receive-side scaling (RSS) is supported for multi-core scaling.
-
-The ENA driver and its corresponding devices implement health
-monitoring mechanisms such as watchdog, enabling the device and driver
-to recover in a manner transparent to the application, as well as
-debug logs.
-
-Some of the ENA devices support a working mode called Low-latency
-Queue (LLQ), which saves several more microseconds.

-
-Management Interface:
-=====================
-
-ENA management interface is exposed by means of:
-
-- PCIe Configuration Space
-- Device Registers
-- Admin Queue (AQ) and Admin Completion Queue (ACQ)
-- Asynchronous Event Notification Queue (AENQ)
-
-ENA device MMIO Registers are accessed only during driver
-initialization and are not involved in further normal device
-operation.
-
-AQ is used for submitting management commands, and the
-results/responses are reported asynchronously through ACQ.
-
-ENA introduces a small set of management commands with room for
-vendor-specific extensions. Most of the management operations are
-framed in a generic Get/Set feature command.
-
-The following admin queue commands are supported:
-
-- Create I/O submission queue
-- Create I/O completion queue
-- Destroy I/O submission queue
-- Destroy I/O completion queue
-- Get feature
-- Set feature
-- Configure AENQ
-- Get statistics
-
-Refer to ena_admin_defs.h for the list of supported Get/Set Feature
-properties.
-
-The Asynchronous Event Notification Queue (AENQ) is a uni-directional
-queue used by the ENA device to send to the driver events that cannot
-be reported using ACQ. AENQ events are subdivided into groups. Each
-group may have multiple syndromes, as shown below
-
-The events are:
-
-	====================	===============
-	Group			Syndrome
-	====================	===============
-	Link state change	**X**
-	Fatal error		**X**
-	Notification		Suspend traffic
-	Notification		Resume traffic
-	Keep-Alive		**X**
-	====================	===============
-
-ACQ and AENQ share the same MSI-X vector.
-
-Keep-Alive is a special mechanism that allows monitoring of the
-device's health. The driver maintains a watchdog (WD) handler which,
-if fired, logs the current state and statistics then resets and
-restarts the ENA device and driver. A Keep-Alive event is delivered by
-the device every second. The driver re-arms the WD upon reception of a
-Keep-Alive event. A missed Keep-Alive event causes the WD handler to
-fire.
-
-Data Path Interface
-===================
-I/O operations are based on Tx and Rx Submission Queues (Tx SQ and Rx
-SQ correspondingly). Each SQ has a completion queue (CQ) associated
-with it.
-
-The SQs and CQs are implemented as descriptor rings in contiguous
-physical memory.
-
-The ENA driver supports two Queue Operation modes for Tx SQs:
-
-- Regular mode
-
-  * In this mode the Tx SQs reside in the host's memory. The ENA
-    device fetches the ENA Tx descriptors and packet data from host
-    memory.
-
-- Low Latency Queue (LLQ) mode or "push-mode".
-
-  * In this mode the driver pushes the transmit descriptors and the
-    first 128 bytes of the packet directly to the ENA device memory
-    space. The rest of the packet payload is fetched by the
-    device. For this operation mode, the driver uses a dedicated PCI
-    device memory BAR, which is mapped with write-combine capability.
-
-The Rx SQs support only the regular mode.
-
-Note: Not all ENA devices support LLQ, and this feature is negotiated
-      with the device upon initialization. If the ENA device does not
-      support LLQ mode, the driver falls back to the regular mode.
-
-The driver supports multi-queue for both Tx and Rx. This has various
-benefits:
-
-- Reduced CPU/thread/process contention on a given Ethernet interface.
-- Cache miss rate on completion is reduced, particularly for data
-  cache lines that hold the sk_buff structures.
-- Increased process-level parallelism when handling received packets.
-- Increased data cache hit rate, by steering kernel processing of
-  packets to the CPU, where the application thread consuming the
-  packet is running.
-- In hardware interrupt re-direction.
-
-Interrupt Modes
-===============
-The driver assigns a single MSI-X vector per queue pair (for both Tx
-and Rx directions). The driver assigns an additional dedicated MSI-X vector
-for management (for ACQ and AENQ).
-
-Management interrupt registration is performed when the Linux kernel
-probes the adapter, and it is de-registered when the adapter is
-removed. I/O queue interrupt registration is performed when the Linux
-interface of the adapter is opened, and it is de-registered when the
-interface is closed.
-
-The management interrupt is named::
-
-   ena-mgmnt@pci:<PCI domain:bus:slot.function>
-
-and for each queue pair, an interrupt is named::
-
-   <interface name>-Tx-Rx-<queue index>
-
-The ENA device operates in auto-mask and auto-clear interrupt
-modes. That is, once MSI-X is delivered to the host, its Cause bit is
-automatically cleared and the interrupt is masked. The interrupt is
-unmasked by the driver after NAPI processing is complete.
-
-Interrupt Moderation
-====================
-ENA driver and device can operate in conventional or adaptive interrupt
-moderation mode.
-
-In conventional mode the driver instructs device to postpone interrupt
-posting according to static interrupt delay value. The interrupt delay
-value can be configured through ethtool(8). The following ethtool
-parameters are supported by the driver: tx-usecs, rx-usecs
-
-In adaptive interrupt moderation mode the interrupt delay value is
-updated by the driver dynamically and adjusted every NAPI cycle
-according to the traffic nature.
-
-By default ENA driver applies adaptive coalescing on Rx traffic and
-conventional coalescing on Tx traffic.
-
-Adaptive coalescing can be switched on/off through ethtool(8)
-adaptive_rx on|off parameter.
-
-The driver chooses interrupt delay value according to the number of
-bytes and packets received between interrupt unmasking and interrupt
-posting. The driver uses interrupt delay table that subdivides the
-range of received bytes/packets into 5 levels and assigns interrupt
-delay value to each level.
-
-The user can enable/disable adaptive moderation, modify the interrupt
-delay table and restore its default values through sysfs.
-
-RX copybreak
-============
-The rx_copybreak is initialized by default to ENA_DEFAULT_RX_COPYBREAK
-and can be configured by the ETHTOOL_STUNABLE command of the
-SIOCETHTOOL ioctl.
-
-SKB
-===
-The driver-allocated SKB for frames received from Rx handling using
-NAPI context. The allocation method depends on the size of the packet.
-If the frame length is larger than rx_copybreak, napi_get_frags()
-is used, otherwise netdev_alloc_skb_ip_align() is used, the buffer
-content is copied (by CPU) to the SKB, and the buffer is recycled.
-
-Statistics
-==========
-The user can obtain ENA device and driver statistics using ethtool.
-The driver can collect regular or extended statistics (including
-per-queue stats) from the device.
-
-In addition the driver logs the stats to syslog upon device reset.
-
-MTU
-===
-The driver supports an arbitrarily large MTU with a maximum that is
-negotiated with the device. The driver configures MTU using the
-SetFeature command (ENA_ADMIN_MTU property). The user can change MTU
-via ip(8) and similar legacy tools.
-
-Stateless Offloads
-==================
-The ENA driver supports:
-
-- TSO over IPv4/IPv6
-- TSO with ECN
-- IPv4 header checksum offload
-- TCP/UDP over IPv4/IPv6 checksum offloads
-
-RSS
-===
-- The ENA device supports RSS that allows flexible Rx traffic
-  steering.
-- Toeplitz and CRC32 hash functions are supported.
-- Different combinations of L2/L3/L4 fields can be configured as
-  inputs for hash functions.
-- The driver configures RSS settings using the AQ SetFeature command
-  (ENA_ADMIN_RSS_HASH_FUNCTION, ENA_ADMIN_RSS_HASH_INPUT and
-  ENA_ADMIN_RSS_REDIRECTION_TABLE_CONFIG properties).
-- If the NETIF_F_RXHASH flag is set, the 32-bit result of the hash
-  function delivered in the Rx CQ descriptor is set in the received
-  SKB.
-- The user can provide a hash key, hash function, and configure the
-  indirection table through ethtool(8).
-
-DATA PATH
-=========
-Tx
---
-
-end_start_xmit() is called by the stack. This function does the following:
-
-- Maps data buffers (skb->data and frags).
-- Populates ena_buf for the push buffer (if the driver and device are
-  in push mode.)
-- Prepares ENA bufs for the remaining frags.
-- Allocates a new request ID from the empty req_id ring. The request
-  ID is the index of the packet in the Tx info. This is used for
-  out-of-order TX completions.
-- Adds the packet to the proper place in the Tx ring.
-- Calls ena_com_prepare_tx(), an ENA communication layer that converts
-  the ena_bufs to ENA descriptors (and adds meta ENA descriptors as
-  needed.)
-
-  * This function also copies the ENA descriptors and the push buffer
-    to the Device memory space (if in push mode.)
-
-- Writes doorbell to the ENA device.
-- When the ENA device finishes sending the packet, a completion
-  interrupt is raised.
-- The interrupt handler schedules NAPI.
-- The ena_clean_tx_irq() function is called. This function handles the
-  completion descriptors generated by the ENA, with a single
-  completion descriptor per completed packet.
-
-  * req_id is retrieved from the completion descriptor. The tx_info of
-    the packet is retrieved via the req_id. The data buffers are
-    unmapped and req_id is returned to the empty req_id ring.
-  * The function stops when the completion descriptors are completed or
-    the budget is reached.
-
-Rx
---
-
-- When a packet is received from the ENA device.
-- The interrupt handler schedules NAPI.
-- The ena_clean_rx_irq() function is called. This function calls
-  ena_rx_pkt(), an ENA communication layer function, which returns the
-  number of descriptors used for a new unhandled packet, and zero if
-  no new packet is found.
-- Then it calls the ena_clean_rx_irq() function.
-- ena_eth_rx_skb() checks packet length:
-
-  * If the packet is small (len < rx_copybreak), the driver allocates
-    a SKB for the new packet, and copies the packet payload into the
-    SKB data buffer.
-
-    - In this way the original data buffer is not passed to the stack
-      and is reused for future Rx packets.
-
-  * Otherwise the function unmaps the Rx buffer, then allocates the
-    new SKB structure and hooks the Rx buffer to the SKB frags.
-
-- The new SKB is updated with the necessary information (protocol,
-  checksum hw verify result, etc.), and then passed to the network
-  stack, using the NAPI interface function napi_gro_receive().

-
- and changed with::
-
-    ethtool -C <ethX> tx-usecs <usecs> rx-usecs <usecs>
-
- To disable coalescing::
-

--------------------
-
- WOL support by magic packet::
-
-    ethtool -s <ethX> wol g
-
- To disable WOL::
-
-    ethtool -s <ethX> wol d
-
-Set and check the driver message level
---------------------------------------
-
- Set message level
-
- ::
-
-    ethtool -s <ethX> msglvl <level>
-
- Level values:
-
- ======   =============================
- 0x0001   general driver status.
- 0x0002   hardware probing.
- 0x0004   link state.
- 0x0008   periodic status check.
- 0x0010   interface being brought down.
- 0x0020   interface being brought up.
- 0x0040   receive error.
- 0x0080   transmit error.
- 0x0200   interrupt handling.
- 0x0400   transmit completion.
- 0x0800   receive completion.
- 0x1000   packet contents.
- 0x2000   hardware status.
- 0x4000   Wake-on-LAN status.
- ======   =============================
-
- By default, the level of debugging messages is set 0x0001(general driver status).
-
- Check message level
-
- ::
-
-    ethtool <ethX> | grep "Current message level"
-
- If you want to disable the output of messages::
-
-    ethtool -s <ethX> msglvl 0
-
-RX flow rules (ntuple filters)
-------------------------------
-
- There are separate rules supported, that applies in that order:
-
- 1. 16 VLAN ID rules
- 2. 16 L2 EtherType rules
- 3. 8 L3/L4 5-Tuple rules
-
-
- The driver utilizes the ethtool interface for configuring ntuple filters,
- via ``ethtool -N <device> <filter>``.
-
- To enable or disable the RX flow rules::
-
-    ethtool -K ethX ntuple <on|off>
-
- When disabling ntuple filters, all the user programed filters are
- flushed from the driver cache and hardware. All needed filters must
- be re-added when ntuple is re-enabled.
-
- Because of the fixed order of the rules, the location of filters is also fixed:
-
- - Locations 0 - 15 for VLAN ID filters
- - Locations 16 - 31 for L2 EtherType filters
- - Locations 32 - 39 for L3/L4 5-tuple filters (locations 32, 36 for IPv6)
-
- The L3/L4 5-tuple (protocol, source and destination IP address, source and
- destination TCP/UDP/SCTP port) is compared against 8 filters. For IPv4, up to
- 8 source and destination addresses can be matched. For IPv6, up to 2 pairs of
- addresses can be supported. Source and destination ports are only compared for
- TCP/UDP/SCTP packets.
-
- To add a filter that directs packet to queue 5, use
- ``<-N|-U|--config-nfc|--config-ntuple>`` switch::
-
-    ethtool -N <ethX> flow-type udp4 src-ip 10.0.0.1 dst-ip 10.0.0.2 src-port 2000 dst-port 2001 action 5 <loc 32>
-
- - action is the queue number.
- - loc is the rule number.
-
- For ``flow-type ip4|udp4|tcp4|sctp4|ip6|udp6|tcp6|sctp6`` you must set the loc
- number within 32 - 39.
- For ``flow-type ip4|udp4|tcp4|sctp4|ip6|udp6|tcp6|sctp6`` you can set 8 rules
- for traffic IPv4 or you can set 2 rules for traffic IPv6. Loc number traffic
- IPv6 is 32 and 36.
- At the moment you can not use IPv4 and IPv6 filters at the same time.
-
- Example filter for IPv6 filter traffic::
-
-    sudo ethtool -N <ethX> flow-type tcp6 src-ip 2001:db8:0:f101::1 dst-ip 2001:db8:0:f101::2 action 1 loc 32
-    sudo ethtool -N <ethX> flow-type ip6 src-ip 2001:db8:0:f101::2 dst-ip 2001:db8:0:f101::5 action -1 loc 36
-
- Example filter for IPv4 filter traffic::
-
-    sudo ethtool -N <ethX> flow-type udp4 src-ip 10.0.0.4 dst-ip 10.0.0.7 src-port 2000 dst-port 2001 loc 32
-    sudo ethtool -N <ethX> flow-type tcp4 src-ip 10.0.0.3 dst-ip 10.0.0.9 src-port 2000 dst-port 2001 loc 33
-    sudo ethtool -N <ethX> flow-type ip4 src-ip 10.0.0.6 dst-ip 10.0.0.4 loc 34
-
- If you set action -1, then all traffic corresponding to the filter will be discarded.
-
- The maximum value action is 31.
-
-
- The VLAN filter (VLAN id) is compared against 16 filters.
- VLAN id must be accompanied by mask 0xF000. That is to distinguish VLAN filter
- from L2 Ethertype filter with UserPriority since both User Priority and VLAN ID
- are passed in the same 'vlan' parameter.
-
- To add a filter that directs packets from VLAN 2001 to queue 5::
-
-    ethtool -N <ethX> flow-type ip4 vlan 2001 m 0xF000 action 1 loc 0
-
-
- L2 EtherType filters allows filter packet by EtherType field or both EtherType
- and User Priority (PCP) field of 802.1Q.
- UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That is to
- distinguish VLAN filter from L2 Ethertype filter with UserPriority since both
- User Priority and VLAN ID are passed in the same 'vlan' parameter.
-
- To add a filter that directs IP4 packess of priority 3 to queue 3::
-
-    ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF action 3 loc 16
-
- To see the list of filters currently present::
-
-    ethtool <-u|-n|--show-nfc|--show-ntuple> <ethX>
-
- Rules may be deleted from the table itself. This is done using::
-
-    sudo ethtool <-N|-U|--config-nfc|--config-ntuple> <ethX> delete <loc>
-
- - loc is the rule number to be deleted.
-
- Rx filters is an interface to load the filter table that funnels all flow
- into queue 0 unless an alternative queue is specified using "action". In that
- case, any flow that matches the filter criteria will be directed to the
- appropriate queue. RX filters is supported on all kernels 2.6.30 and later.
-
-RSS for UDP
------------
-
- Currently, NIC does not support RSS for fragmented IP packets, which leads to
- incorrect working of RSS for fragmented UDP traffic. To disable RSS for UDP the
- RX Flow L3/L4 rule may be used.
-
- Example::
-
-    ethtool -N eth0 flow-type udp4 action 0 loc 32
-
-UDP GSO hardware offload
-------------------------
-
- UDP GSO allows to boost UDP tx rates by offloading UDP headers allocation
- into hardware. A special userspace socket option is required for this,
- could be validated with /kernel/tools/testing/selftests/net/::
-
-    udpgso_bench_tx -u -4 -D 10.0.1.1 -s 6300 -S 100
-
- Will cause sending out of 100 byte sized UDP packets formed from single
- 6300 bytes user buffer.
-
- UDP GSO is configured by::
-
-    ethtool -K eth0 tx-udp-segmentation on
-
-Private flags (testing)
------------------------
-
- Atlantic driver supports private flags for hardware custom features::
-
-	$ ethtool --show-priv-flags ethX
-
-	Private flags for ethX:
-	DMASystemLoopback  : off
-	PKTSystemLoopback  : off
-	DMANetworkLoopback : off
-	PHYInternalLoopback: off
-	PHYExternalLoopback: off
-
- Example::
-
-	$ ethtool --set-priv-flags ethX DMASystemLoopback on
-
- DMASystemLoopback:   DMA Host loopback.
- PKTSystemLoopback:   Packet buffer host loopback.
- DMANetworkLoopback:  Network side loopback on DMA block.
- PHYInternalLoopback: Internal loopback on Phy.
- PHYExternalLoopback: External loopback on Phy (with loopback ethernet cable).
-
-
-Command Line Parameters
-=======================
-The following command line parameters are available on atlantic driver:
-
-aq_itr -Interrupt throttling mode
----------------------------------
-Accepted values: 0, 1, 0xFFFF
-
-Default value: 0xFFFF
-
-======   ==============================================================
-0        Disable interrupt throttling.
-1        Enable interrupt throttling and use specified tx and rx rates.
-0xFFFF   Auto throttling mode. Driver will choose the best RX and TX
-	 interrupt throtting settings based on link speed.
-======   ==============================================================
-
-aq_itr_tx - TX interrupt throttle rate
---------------------------------------
-
-Accepted values: 0 - 0x1FF
-
-Default value: 0
-
-TX side throttling in microseconds. Adapter will setup maximum interrupt delay
-to this value. Minimum interrupt delay will be a half of this value
-
-aq_itr_rx - RX interrupt throttle rate
---------------------------------------
-
-Accepted values: 0 - 0x1FF
-
-Default value: 0
-
-RX side throttling in microseconds. Adapter will setup maximum interrupt delay
-to this value. Minimum interrupt delay will be a half of this value
-
-.. note::
-
-   ITR settings could be changed in runtime by ethtool -c means (see below)
-
-Config file parameters
-======================
-
-For some fine tuning and performance optimizations,
-some parameters can be changed in the {source_dir}/aq_cfg.h file.
-
-AQ_CFG_RX_PAGEORDER
--------------------
-
-Default value: 0
-
-RX page order override. Thats a power of 2 number of RX pages allocated for
-each descriptor. Received descriptor size is still limited by
-AQ_CFG_RX_FRAME_MAX.
-
-Increasing pageorder makes page reuse better (actual on iommu enabled systems).
-
-AQ_CFG_RX_REFILL_THRES
-----------------------
-
-Default value: 32
-
-RX refill threshold. RX path will not refill freed descriptors until the
-specified number of free descriptors is observed. Larger values may help
-better page reuse but may lead to packet drops as well.
-
-AQ_CFG_VECS_DEF
----------------
-
-Number of queues
-
-Valid Range: 0 - 8 (up to AQ_CFG_VECS_MAX)
-
-Default value: 8
-
-Notice this value will be capped by the number of cores available on the system.
-
-AQ_CFG_IS_RSS_DEF
------------------
-
-Enable/disable Receive Side Scaling
-
-This feature allows the adapter to distribute receive processing
-across multiple CPU-cores and to prevent from overloading a single CPU core.
-
-Valid values
-
-==  ========
-0   disabled
-1   enabled
-==  ========
-
-Default value: 1
-
-AQ_CFG_NUM_RSS_QUEUES_DEF
--------------------------
-
-Number of queues for Receive Side Scaling
-
-Valid Range: 0 - 8 (up to AQ_CFG_VECS_DEF)
-
-Default value: AQ_CFG_VECS_DEF
-
-AQ_CFG_IS_LRO_DEF
------------------
-
-Enable/disable Large Receive Offload
-
-This offload enables the adapter to coalesce multiple TCP segments and indicate
-them as a single coalesced unit to the OS networking subsystem.
-
-The system consumes less energy but it also introduces more latency in packets
-processing.
-
-Valid values
-
-==  ========
-0   disabled
-1   enabled
-==  ========
-
-Default value: 1
-
-AQ_CFG_TX_CLEAN_BUDGET
-----------------------
-
-Maximum descriptors to cleanup on TX at once.
-
-Default value: 256
-
-After the aq_cfg.h file changed the driver must be rebuilt to take effect.
-
-Support
-=======

+===================
+SB100 device driver
+===================
+
+sb1000 is a module network device driver for the General Instrument (also known
+as NextLevel) SURFboard1000 internal cable modem board.  This is an ISA card
+which is used by a number of cable TV companies to provide cable modem access.
+It's a one-way downstream-only cable modem, meaning that your upstream net link
+is provided by your regular phone modem.
+
+This driver was written by Franco Venturi <fventuri@mediaone.net>.  He deserves
+a great deal of thanks for this wonderful piece of code!
+
+Needed tools
+============
+
+Support for this device is now a part of the standard Linux kernel.  The
+driver source code file is drivers/net/sb1000.c.  In addition to this
+you will need:
+
+1. The "cmconfig" program.  This is a utility which supplements "ifconfig"
+   to configure the cable modem and network interface (usually called "cm0");
+
+2. Several PPP scripts which live in /etc/ppp to make connecting via your
+   cable modem easy.
+
+   These utilities can be obtained from:
+
+      http://www.jacksonville.net/~fventuri/
+
+   in Franco's original source code distribution .tar.gz file.  Support for
+   the sb1000 driver can be found at:
+
+      - http://web.archive.org/web/%2E/http://home.adelphia.net/~siglercm/sb1000.html
+      - http://web.archive.org/web/%2E/http://linuxpower.cx/~cable/
+
+   along with these utilities.
+
+3. The standard isapnp tools.  These are necessary to configure your SB1000
+   card at boot time (or afterwards by hand) since it's a PnP card.
+
+   If you don't have these installed as a standard part of your Linux
+   distribution, you can find them at:
+
+      http://www.roestock.demon.co.uk/isapnptools/
+
+   or check your Linux distribution binary CD or their web site.  For help with
+   isapnp, pnpdump, or /etc/isapnp.conf, go to:
+
+      http://www.roestock.demon.co.uk/isapnptools/isapnpfaq.html
+
+Using the driver
+================
+
+To make the SB1000 card work, follow these steps:
+
+1. Run ``make config``, or ``make menuconfig``, or ``make xconfig``, whichever
+   you prefer, in the top kernel tree directory to set up your kernel
+   configuration.  Make sure to say "Y" to "Prompt for development drivers"
+   and to say "M" to the sb1000 driver.  Also say "Y" or "M" to all the standard
+   networking questions to get TCP/IP and PPP networking support.
+
+2. **BEFORE** you build the kernel, edit drivers/net/sb1000.c.  Make sure
+   to redefine the value of READ_DATA_PORT to match the I/O address used
+   by isapnp to access your PnP cards.  This is the value of READPORT in
+   /etc/isapnp.conf or given by the output of pnpdump.
+
+3. Build and install the kernel and modules as usual.
+
+4. Boot your new kernel following the usual procedures.
+
+5. Set up to configure the new SB1000 PnP card by capturing the output
+   of "pnpdump" to a file and editing this file to set the correct I/O ports,
+   IRQ, and DMA settings for all your PnP cards.  Make sure none of the settings
+   conflict with one another.  Then test this configuration by running the
+   "isapnp" command with your new config file as the input.  Check for
+   errors and fix as necessary.  (As an aside, I use I/O ports 0x110 and
+   0x310 and IRQ 11 for my SB1000 card and these work well for me.  YMMV.)
+   Then save the finished config file as /etc/isapnp.conf for proper
+   configuration on subsequent reboots.
+
+6. Download the original file sb1000-1.1.2.tar.gz from Franco's site or one of
+   the others referenced above.  As root, unpack it into a temporary directory
+   and do a ``make cmconfig`` and then ``install -c cmconfig /usr/local/sbin``.
+   Don't do ``make install`` because it expects to find all the utilities built
+   and ready for installation, not just cmconfig.
+
+7. As root, copy all the files under the ppp/ subdirectory in Franco's
+   tar file into /etc/ppp, being careful not to overwrite any files that are
+   already in there.  Then modify ppp@gi-on to set the correct login name,
+   phone number, and frequency for the cable modem.  Also edit pap-secrets
+   to specify your login name and password and any site-specific information
+   you need.
+
+8. Be sure to modify /etc/ppp/firewall to use ipchains instead of
+   the older ipfwadm commands from the 2.0.x kernels.  There's a neat utility to
+   convert ipfwadm commands to ipchains commands:
+
+	http://users.dhp.com/~whisper/ipfwadm2ipchains/
+
+   You may also wish to modify the firewall script to implement a different
+   firewalling scheme.
+
+9. Start the PPP connection via the script /etc/ppp/ppp@gi-on.  You must be
+   root to do this.  It's better to use a utility like sudo to execute
+   frequently used commands like this with root permissions if possible.  If you
+   connect successfully the cable modem interface will come up and you'll see a
+   driver message like this at the console::
+
+	 cm0: sb1000 at (0x110,0x310), csn 1, S/N 0x2a0d16d8, IRQ 11.
+	 sb1000.c:v1.1.2 6/01/98 (fventuri@mediaone.net)
+
+   The "ifconfig" command should show two new interfaces, ppp0 and cm0.
+
+   The command "cmconfig cm0" will give you information about the cable modem
+   interface.
+
+10. Try pinging a site via ``ping -c 5 www.yahoo.com``, for example.  You should
+    see packets received.
+
+11. If you can't get site names (like www.yahoo.com) to resolve into
+    IP addresses (like 204.71.200.67), be sure your /etc/resolv.conf file
+    has no syntax errors and has the right nameserver IP addresses in it.
+    If this doesn't help, try something like ``ping -c 5 204.71.200.67`` to
+    see if the networking is running but the DNS resolution is where the
+    problem lies.
+
+12. If you still have problems, go to the support web sites mentioned above
+    and read the information and documentation there.
+
+Common problems
+===============
+
+1. Packets go out on the ppp0 interface but don't come back on the cm0
+   interface.  It looks like I'm connected but I can't even ping any
+   numerical IP addresses.  (This happens predominantly on Debian systems due
+   to a default boot-time configuration script.)
+
+Solution
+   As root ``echo 0 > /proc/sys/net/ipv4/conf/cm0/rp_filter`` so it
+   can share the same IP address as the ppp0 interface.  Note that this
+   command should probably be added to the /etc/ppp/cablemodem script
+   *right*between* the "/sbin/ifconfig" and "/sbin/cmconfig" commands.
+   You may need to do this to /proc/sys/net/ipv4/conf/ppp0/rp_filter as well.
+   If you do this to /proc/sys/net/ipv4/conf/default/rp_filter on each reboot
+   (in rc.local or some such) then any interfaces can share the same IP
+   addresses.
+
+2. I get "unresolved symbol" error messages on executing ``insmod sb1000.o``.
+
+Solution
+   You probably have a non-matching kernel source tree and
+   /usr/include/linux and /usr/include/asm header files.  Make sure you
+   install the correct versions of the header files in these two directories.
+   Then rebuild and reinstall the kernel.
+
+3. When isapnp runs it reports an error, and my SB1000 card isn't working.
+
+Solution
+   There's a problem with later versions of isapnp using the "(CHECK)"
+   option in the lines that allocate the two I/O addresses for the SB1000 card.
+   This first popped up on RH 6.0.  Delete "(CHECK)" for the SB1000 I/O addresses.
+   Make sure they don't conflict with any other pieces of hardware first!  Then
+   rerun isapnp and go from there.
+
+4. I can't execute the /etc/ppp/ppp@gi-on file.
+
+Solution
+   As root do ``chmod ug+x /etc/ppp/ppp@gi-on``.
+
+5. The firewall script isn't working (with 2.2.x and higher kernels).
+
+Solution
+   Use the ipfwadm2ipchains script referenced above to convert the
+   /etc/ppp/firewall script from the deprecated ipfwadm commands to ipchains.
+
+6. I'm getting *tons* of firewall deny messages in the /var/kern.log,
+   /var/messages, and/or /var/syslog files, and they're filling up my /var
+   partition!!!
+
+Solution
+   First, tell your ISP that you're receiving DoS (Denial of Service)
+   and/or portscanning (UDP connection attempts) attacks!  Look over the deny
+   messages to figure out what the attack is and where it's coming from.  Next,
+   edit /etc/ppp/cablemodem and make sure the ",nobroadcast" option is turned on
+   to the "cmconfig" command (uncomment that line).  If you're not receiving these
+   denied packets on your broadcast interface (IP address xxx.yyy.zzz.255
+   typically), then someone is attacking your machine in particular.  Be careful
+   out there....
+
+7. Everything seems to work fine but my computer locks up after a while
+   (and typically during a lengthy download through the cable modem)!
+
+Solution
+   You may need to add a short delay in the driver to 'slow down' the
+   SURFboard because your PC might not be able to keep up with the transfer rate
+   of the SB1000. To do this, it's probably best to download Franco's
+   sb1000-1.1.2.tar.gz archive and build and install sb1000.o manually.  You'll
+   want to edit the 'Makefile' and look for the 'SB1000_DELAY'
+   define.  Uncomment those 'CFLAGS' lines (and comment out the default ones)
+   and try setting the delay to something like 60 microseconds with:
+   '-DSB1000_DELAY=60'.  Then do ``make`` and as root ``make install`` and try
+   it out.  If it still doesn't work or you like playing with the driver, you may
+   try other numbers.  Remember though that the higher the delay, the slower the
+   driver (which slows down the rest of the PC too when it is actively
+   used). Thanks to Ed Daiga for this tip!

+Rmnet Driver
+============
+
+1. Introduction
+===============
+
+rmnet driver is used for supporting the Multiplexing and aggregation
+Protocol (MAP). This protocol is used by all recent chipsets using Qualcomm
+Technologies, Inc. modems.
+
+This driver can be used to register onto any physical network device in
+IP mode. Physical transports include USB, HSIC, PCIe and IP accelerator.
+
+Multiplexing allows for creation of logical netdevices (rmnet devices) to
+handle multiple private data networks (PDN) like a default internet, tethering,
+multimedia messaging service (MMS) or IP media subsystem (IMS). Hardware sends
+packets with MAP headers to rmnet. Based on the multiplexer id, rmnet
+routes to the appropriate PDN after removing the MAP header.
+
+Aggregation is required to achieve high data rates. This involves hardware
+sending aggregated bunch of MAP frames. rmnet driver will de-aggregate
+these MAP frames and send them to appropriate PDN's.
+
+2. Packet format
+================
+
+a. MAP packet (data / control)
+
+MAP header has the same endianness of the IP packet.
+
+Packet format::
+
+  Bit             0             1           2-7      8 - 15           16 - 31
+  Function   Command / Data   Reserved     Pad   Multiplexer ID    Payload length
+  Bit            32 - x
+  Function     Raw  Bytes
+
+Command (1)/ Data (0) bit value is to indicate if the packet is a MAP command
+or data packet. Control packet is used for transport level flow control. Data
+packets are standard IP packets.
+
+Reserved bits are usually zeroed out and to be ignored by receiver.
+
+Padding is number of bytes to be added for 4 byte alignment if required by
+hardware.
+
+Multiplexer ID is to indicate the PDN on which data has to be sent.
+
+Payload length includes the padding length but does not include MAP header
+length.
+
+b. MAP packet (command specific)::
+
+    Bit             0             1           2-7      8 - 15           16 - 31
+    Function   Command         Reserved     Pad   Multiplexer ID    Payload length
+    Bit          32 - 39        40 - 45    46 - 47       48 - 63
+    Function   Command name    Reserved   Command Type   Reserved
+    Bit          64 - 95
+    Function   Transaction ID
+    Bit          96 - 127
+    Function   Command data
+
+Command 1 indicates disabling flow while 2 is enabling flow
+
+Command types
+
+= ==========================================
+0 for MAP command request
+1 is to acknowledge the receipt of a command
+2 is for unsupported commands
+3 is for error during processing of commands
+= ==========================================
+
+c. Aggregation
+
+Aggregation is multiple MAP packets (can be data or command) delivered to
+rmnet in a single linear skb. rmnet will process the individual
+packets and either ACK the MAP command or deliver the IP packet to the
+network stack as needed
+
+MAP header|IP Packet|Optional padding|MAP header|IP Packet|Optional padding....
+
+MAP header|IP Packet|Optional padding|MAP header|Command Packet|Optional pad...
+
+3. Userspace configuration
+==========================
+
+rmnet userspace configuration is done through netlink library librmnetctl
+and command line utility rmnetcli. Utility is hosted in codeaurora forum git.
+The driver uses rtnl_link_ops for communication.

- KNOWN ISSUES
- SUPPORT
-
-
-Introduction
-============
-
- This document describes the Linux driver for Chelsio 10Gb Ethernet Network
- Controller. This driver supports the Chelsio N210 NIC and is backward
- compatible with the Chelsio N110 model 10Gb NICs.
-
-
-Features
-========
-
-Adaptive Interrupts (adaptive-rx)
----------------------------------
-
-  This feature provides an adaptive algorithm that adjusts the interrupt
-  coalescing parameters, allowing the driver to dynamically adapt the latency
-  settings to achieve the highest performance during various types of network
-  load.
-
-  The interface used to control this feature is ethtool. Please see the
-  ethtool manpage for additional usage information.
-
-  By default, adaptive-rx is disabled.
-  To enable adaptive-rx::
-
-      ethtool -C <interface> adaptive-rx on
-
-  To disable adaptive-rx, use ethtool::
-
-      ethtool -C <interface> adaptive-rx off
-
-  After disabling adaptive-rx, the timer latency value will be set to 50us.
-  You may set the timer latency after disabling adaptive-rx::
-
-      ethtool -C <interface> rx-usecs <microseconds>
-
-  An example to set the timer latency value to 100us on eth0::
-
-      ethtool -C eth0 rx-usecs 100
-
-  You may also provide a timer latency value while disabling adaptive-rx::
-
-      ethtool -C <interface> adaptive-rx off rx-usecs <microseconds>
-
-  If adaptive-rx is disabled and a timer latency value is specified, the timer
-  will be set to the specified value until changed by the user or until
-  adaptive-rx is enabled.
-
-  To view the status of the adaptive-rx and timer latency values::
-
-      ethtool -c <interface>
-
-
-TCP Segmentation Offloading (TSO) Support
------------------------------------------
-
-  This feature, also known as "large send", enables a system's protocol stack
-  to offload portions of outbound TCP processing to a network interface card
-  thereby reducing system CPU utilization and enhancing performance.
-
-  The interface used to control this feature is ethtool version 1.8 or higher.
-  Please see the ethtool manpage for additional usage information.
-
-  By default, TSO is enabled.
-  To disable TSO::
-
-      ethtool -K <interface> tso off
-
-  To enable TSO::
-
-      ethtool -K <interface> tso on
-
-  To view the status of TSO::
-
-      ethtool -k <interface>
-
-
-Performance
-===========
-
- The following information is provided as an example of how to change system
- parameters for "performance tuning" an what value to use. You may or may not
- want to change these system parameters, depending on your server/workstation
- application. Doing so is not warranted in any way by Chelsio Communications,
- and is done at "YOUR OWN RISK". Chelsio will not be held responsible for loss
- of data or damage to equipment.
-
- Your distribution may have a different way of doing things, or you may prefer
- a different method. These commands are shown only to provide an example of
- what to do and are by no means definitive.
-
- Making any of the following system changes will only last until you reboot
- your system. You may want to write a script that runs at boot-up which
- includes the optimal settings for your system.
-
-  Setting PCI Latency Timer::
-
-      setpci -d 1425::
-
-* 0x0c.l=0x0000F800
-
-  Disabling TCP timestamp::
-
-      sysctl -w net.ipv4.tcp_timestamps=0
-
-  Disabling SACK::
-
-      sysctl -w net.ipv4.tcp_sack=0
-
-  Setting large number of incoming connection requests::
-
-      sysctl -w net.ipv4.tcp_max_syn_backlog=3000
-
-  Setting maximum receive socket buffer size::
-
-      sysctl -w net.core.rmem_max=1024000
-
-  Setting maximum send socket buffer size::
-
-      sysctl -w net.core.wmem_max=1024000
-
-  Set smp_affinity (on a multiprocessor system) to a single CPU::
-
-      echo 1 > /proc/irq/<interrupt_number>/smp_affinity
-
-  Setting default receive socket buffer size::
-
-      sysctl -w net.core.rmem_default=524287
-
-  Setting default send socket buffer size::
-
-      sysctl -w net.core.wmem_default=524287
-
-  Setting maximum option memory buffers::
-
-      sysctl -w net.core.optmem_max=524287
-
-  Setting maximum backlog (# of unprocessed packets before kernel drops)::
-
-      sysctl -w net.core.netdev_max_backlog=300000
-
-  Setting TCP read buffers (min/default/max)::
-
-      sysctl -w net.ipv4.tcp_rmem="10000000 10000000 10000000"
-
-  Setting TCP write buffers (min/pressure/max)::
-
-      sysctl -w net.ipv4.tcp_wmem="10000000 10000000 10000000"
-
-  Setting TCP buffer space (min/pressure/max)::
-
-      sysctl -w net.ipv4.tcp_mem="10000000 10000000 10000000"
-
-  TCP window size for single connections:
-
-   The receive buffer (RX_WINDOW) size must be at least as large as the
-   Bandwidth-Delay Product of the communication link between the sender and
-   receiver. Due to the variations of RTT, you may want to increase the buffer
-   size up to 2 times the Bandwidth-Delay Product. Reference page 289 of
-   "TCP/IP Illustrated, Volume 1, The Protocols" by W. Richard Stevens.
-
-   At 10Gb speeds, use the following formula::
-
-       RX_WINDOW >= 1.25MBytes * RTT(in milliseconds)
-       Example for RTT with 100us: RX_WINDOW = (1,250,000 * 0.1) = 125,000
-
-   RX_WINDOW sizes of 256KB - 512KB should be sufficient.
-
-   Setting the min, max, and default receive buffer (RX_WINDOW) size::
-
-       sysctl -w net.ipv4.tcp_rmem="<min> <default> <max>"
-
-  TCP window size for multiple connections:
-   The receive buffer (RX_WINDOW) size may be calculated the same as single
-   connections, but should be divided by the number of connections. The
-   smaller window prevents congestion and facilitates better pacing,
-   especially if/when MAC level flow control does not work well or when it is
-   not supported on the machine. Experimentation may be necessary to attain
-   the correct value. This method is provided as a starting point for the
-   correct receive buffer size.
-
-   Setting the min, max, and default receive buffer (RX_WINDOW) size is
-   performed in the same manner as single connection.
-
-

-
-
-Known Issues
-============
-
- These issues have been identified during testing. The following information
- is provided as a workaround to the problem. In some cases, this problem is
- inherent to Linux or to a particular Linux Distribution and/or hardware
- platform.
-
-  1. Large number of TCP retransmits on a multiprocessor (SMP) system.
-
-      On a system with multiple CPUs, the interrupt (IRQ) for the network
-      controller may be bound to more than one CPU. This will cause TCP
-      retransmits if the packet data were to be split across different CPUs
-      and re-assembled in a different order than expected.
-
-      To eliminate the TCP retransmits, set smp_affinity on the particular
-      interrupt to a single CPU. You can locate the interrupt (IRQ) used on
-      the N110/N210 by using ifconfig::
-
-	  ifconfig <dev_name> | grep Interrupt
-
-      Set the smp_affinity to a single CPU::
-
-	  echo 1 > /proc/irq/<interrupt_number>/smp_affinity
-
-      It is highly suggested that you do not run the irqbalance daemon on your
-      system, as this will change any smp_affinity setting you have applied.
-      The irqbalance daemon runs on a 10 second interval and binds interrupts
-      to the least loaded CPU determined by the daemon. To disable this daemon::
-
-	  chkconfig --level 2345 irqbalance off
-
-      By default, some Linux distributions enable the kernel feature,
-      irqbalance, which performs the same function as the daemon. To disable
-      this feature, add the following line to your bootloader::
-
-	  noirqbalance
-
-	  Example using the Grub bootloader::
-
-	      title Red Hat Enterprise Linux AS (2.4.21-27.ELsmp)
-	      root (hd0,0)
-	      kernel /vmlinuz-2.4.21-27.ELsmp ro root=/dev/hda3 noirqbalance
-	      initrd /initrd-2.4.21-27.ELsmp.img
-
-  2. After running insmod, the driver is loaded and the incorrect network
-     interface is brought up without running ifup.
-
-      When using 2.4.x kernels, including RHEL kernels, the Linux kernel
-      invokes a script named "hotplug". This script is primarily used to
-      automatically bring up USB devices when they are plugged in, however,
-      the script also attempts to automatically bring up a network interface
-      after loading the kernel module. The hotplug script does this by scanning
-      the ifcfg-eth# config files in /etc/sysconfig/network-scripts, looking
-      for HWADDR=<mac_address>.
-
-      If the hotplug script does not find the HWADDRR within any of the
-      ifcfg-eth# files, it will bring up the device with the next available
-      interface name. If this interface is already configured for a different
-      network card, your new interface will have incorrect IP address and
-      network settings.
-
-      To solve this issue, you can add the HWADDR=<mac_address> key to the
-      interface config file of your network controller.
-
-      To disable this "hotplug" feature, you may add the driver (module name)
-      to the "blacklist" file located in /etc/hotplug. It has been noted that
-      this does not work for network devices because the net.agent script
-      does not use the blacklist file. Simply remove, or rename, the net.agent
-      script located in /etc/hotplug to disable this feature.
-
-  3. Transport Protocol (TP) hangs when running heavy multi-connection traffic
-     on an AMD Opteron system with HyperTransport PCI-X Tunnel chipset.
-
-      If your AMD Opteron system uses the AMD-8131 HyperTransport PCI-X Tunnel
-      chipset, you may experience the "133-Mhz Mode Split Completion Data
-      Corruption" bug identified by AMD while using a 133Mhz PCI-X card on the
-      bus PCI-X bus.
-
-      AMD states, "Under highly specific conditions, the AMD-8131 PCI-X Tunnel
-      can provide stale data via split completion cycles to a PCI-X card that
-      is operating at 133 Mhz", causing data corruption.
-
-      AMD's provides three workarounds for this problem, however, Chelsio
-      recommends the first option for best performance with this bug:
-
-	For 133Mhz secondary bus operation, limit the transaction length and
-	the number of outstanding transactions, via BIOS configuration
-	programming of the PCI-X card, to the following:
-
-	   Data Length (bytes): 1k
-
-	   Total allowed outstanding transactions: 2
-
-      Please refer to AMD 8131-HT/PCI-X Errata 26310 Rev 3.08 August 2004,
-      section 56, "133-MHz Mode Split Completion Data Corruption" for more
-      details with this bug and workarounds suggested by AMD.
-
-      It may be possible to work outside AMD's recommended PCI-X settings, try
-      increasing the Data Length to 2k bytes for increased performance. If you
-      have issues with these settings, please revert to the "safe" settings
-      and duplicate the problem before submitting a bug or asking for support.
-
-      .. note::
-
-	    The default setting on most systems is 8 outstanding transactions
-	    and 2k bytes data length.
-
-  4. On multiprocessor systems, it has been noted that an application which
-     is handling 10Gb networking can switch between CPUs causing degraded
-     and/or unstable performance.
-
-      If running on an SMP system and taking performance measurements, it
-      is suggested you either run the latest netperf-2.4.0+ or use a binding
-      tool such as Tim Hockin's procstate utilities (runon)
-      <http://www.hockin.org/~thockin/procstate/>.
-
-      Binding netserver and netperf (or other applications) to particular
-      CPUs will have a significant difference in performance measurements.
-      You may need to experiment which CPU to bind the application to in
-      order to achieve the best performance for your system.
-
-      If you are developing an application designed for 10Gb networking,
-      please keep in mind you may want to look at kernel functions
-      sched_setaffinity & sched_getaffinity to bind your application.
-
-      If you are just running user-space applications such as ftp, telnet,
-      etc., you may want to try the runon tool provided by Tim Hockin's
-      procstate utility. You could also try binding the interface to a
-      particular CPU: runon 0 ifup eth0

-1. Cirrus Logic LAN CS8900/CS8920 Ethernet Adapters
-===================================================
-
-
-1.1. Product Overview
-=====================
-
-The CS8900-based ISA Ethernet Adapters from Cirrus Logic follow
-IEEE 802.3 standards and support half or full-duplex operation in ISA bus
-computers on 10 Mbps Ethernet networks.  The adapters are designed for operation
-in 16-bit ISA or EISA bus expansion slots and are available in
-10BaseT-only or 3-media configurations (10BaseT, 10Base2, and AUI for 10Base-5
-or fiber networks).
-
-CS8920-based adapters are similar to the CS8900-based adapter with additional
-features for Plug and Play (PnP) support and Wakeup Frame recognition.  As
-such, the configuration procedures differ somewhat between the two types of
-adapters.  Refer to the "Adapter Configuration" section for details on
-configuring both types of adapters.
-
-
-1.2. Driver Description
-=======================
-
-The CS8900/CS8920 Ethernet Adapter driver for Linux supports the Linux
-v2.3.48 or greater kernel.  It can be compiled directly into the kernel
-or loaded at run-time as a device driver module.

-
-2. Adapter Installation and Configuration
-=========================================
-
-Both the CS8900 and CS8920-based adapters can be configured using parameters
-stored in an on-board EEPROM. You must use the DOS-based CS8900/20 Setup
-Utility if you want to change the adapter's configuration in EEPROM.
-
-When loading the driver as a module, you can specify many of the adapter's
-configuration parameters on the command-line to override the EEPROM's settings
-or for interface configuration when an EEPROM is not used. (CS8920-based
-adapters must use an EEPROM.) See Section 3.0 LOADING THE DRIVER AS A MODULE.
-
-Since the CS8900/20 Setup Utility is a DOS-based application, you must install
-and configure the adapter in a DOS-based system using the CS8900/20 Setup
-Utility before installation in the target LINUX system.  (Not required if
-installing a CS8900-based adapter and the default configuration is acceptable.)
-
-
-2.1. CS8900-based Adapter Configuration
----------------------------------------
-
-CS8900-based adapters shipped from Cirrus Logic have been configured
-with the following "default" settings::
-
-  Operation Mode:      Memory Mode
-  IRQ:                 10
-  Base I/O Address:    300
-  Memory Base Address: D0000
-  Optimization:	       DOS Client
-  Transmission Mode:   Half-duplex
-  BootProm:            None
-  Media Type:	       Autodetect (3-media cards) or
-		       10BASE-T (10BASE-T only adapter)
-
-You should only change the default configuration settings if conflicts with
-another adapter exists. To change the adapter's configuration, run the
-CS8900/20 Setup Utility.
-
-
-2.2. CS8920-based Adapter Configuration
----------------------------------------
-
-CS8920-based adapters are shipped from Cirrus Logic configured as Plug
-and Play (PnP) enabled.  However, since the cs89x0 driver does NOT
-support PnP, you must install the CS8920 adapter in a DOS-based PC and
-run the CS8900/20 Setup Utility to disable PnP and configure the
-adapter before installation in the target Linux system.  Failure to do
-this will leave the adapter inactive and the driver will be unable to
-communicate with the adapter.

-3. Loading the Driver as a Module
-=================================
-
-If the driver is compiled as a loadable module, you can load the driver module
-with the 'modprobe' command.  Many of the adapter's configuration parameters can
-be specified as command-line arguments to the load command.  This facility
-provides a means to override the EEPROM's settings or for interface
-configuration when an EEPROM is not used.
-
-Example::
-
-    insmod cs89x0.o io=0x200 irq=0xA media=aui
-
-This example loads the module and configures the adapter to use an IO port base
-address of 200h, interrupt 10, and use the AUI media connection.  The following
-configuration options are available on the command line::
-
-  io=###               - specify IO address (200h-360h)
-  irq=##               - specify interrupt level
-  use_dma=1            - Enable DMA
-  dma=#                - specify dma channel (Driver is compiled to support
-			 Rx DMA only)
-  dmasize=# (16 or 64) - DMA size 16K or 64K.  Default value is set to 16.
-  media=rj45           - specify media type
-   or media=bnc
-   or media=aui
-   or media=auto
-  duplex=full          - specify forced half/full/autonegotiate duplex
-   or duplex=half
-   or duplex=auto
-  debug=#              - debug level (only available if the driver was compiled
-			 for debugging)
-
-**Notes:**
-
-a) If an EEPROM is present, any specified command-line parameter
-   will override the corresponding configuration value stored in
-   EEPROM.
-
-b) The "io" parameter must be specified on the command-line.
-
-c) The driver's hardware probe routine is designed to avoid
-   writing to I/O space until it knows that there is a cs89x0
-   card at the written addresses.  This could cause problems
-   with device probing.  To avoid this behaviour, add one
-   to the ``io=`` module parameter.  This doesn't actually change
-   the I/O address, but it is a flag to tell the driver
-   to partially initialise the hardware before trying to
-   identify the card.  This could be dangerous if you are
-   not sure that there is a cs89x0 card at the provided address.
-
-   For example, to scan for an adapter located at IO base 0x300,
-   specify an IO address of 0x301.
-
-d) The "duplex=auto" parameter is only supported for the CS8920.
-
-e) The minimum command-line configuration required if an EEPROM is
-   not present is:
-
-   io
-   irq
-   media type (no autodetect)
-
-f) The following additional parameters are CS89XX defaults (values
-   used with no EEPROM or command-line argument).
-
-   * DMA Burst = enabled
-   * IOCHRDY Enabled = enabled
-   * UseSA = enabled
-   * CS8900 defaults to half-duplex if not specified on command-line
-   * CS8920 defaults to autoneg if not specified on command-line
-   * Use reset defaults for other config parameters
-   * dma_mode = 0
-
-g) You can use ifconfig to set the adapter's Ethernet address.
-
-h) Many Linux distributions use the 'modprobe' command to load
-   modules.  This program uses the '/etc/conf.modules' file to
-   determine configuration information which is passed to a driver
-   module when it is loaded.  All the configuration options which are
-   described above may be placed within /etc/conf.modules.
-
-   For example::
-
-     > cat /etc/conf.modules
-     ...
-     alias eth0 cs89x0
-     options cs89x0 io=0x0200 dma=5 use_dma=1
-     ...
-
-   In this example we are telling the module system that the
-   ethernet driver for this machine should use the cs89x0 driver.  We
-   are asking 'modprobe' to pass the 'io', 'dma' and 'use_dma'
-   arguments to the driver when it is loaded.
-
-i) Cirrus recommend that the cs89x0 use the ISA DMA channels 5, 6 or
-   7.  You will probably find that other DMA channels will not work.
-
-j) The cs89x0 supports DMA for receiving only.  DMA mode is
-   significantly more efficient.  Flooding a 400 MHz Celeron machine
-   with large ping packets consumes 82% of its CPU capacity in non-DMA
-   mode.  With DMA this is reduced to 45%.
-
-k) If your Linux kernel was compiled with inbuilt plug-and-play
-   support you will be able to find information about the cs89x0 card
-   with the command::
-
-     cat /proc/isapnp
-
-l) If during DMA operation you find erratic behavior or network data
-   corruption you should use your PC's BIOS to slow the EISA bus clock.
-
-m) If the cs89x0 driver is compiled directly into the kernel
-   (non-modular) then its I/O address is automatically determined by
-   ISA bus probing.  The IRQ number, media options, etc are determined
-   from the card's EEPROM.
-
-n) If the cs89x0 driver is compiled directly into the kernel, DMA
-   mode may be selected by providing the kernel with a boot option
-   'cs89x0_dma=N' where 'N' is the desired DMA channel number (5, 6 or 7).
-
-   Kernel boot options may be provided on the LILO command line::
-
-	LILO boot: linux cs89x0_dma=5
-
-   or they may be placed in /etc/lilo.conf::
-
-	image=/boot/bzImage-2.3.48
-	  append="cs89x0_dma=5"
-	  label=linux
-	  root=/dev/hda5
-	  read-only
-
-   The DMA Rx buffer size is hardwired to 16 kbytes in this mode.
-   (64k mode is not available).
-
-
-4. Compiling the Driver
-=======================
-
-The cs89x0 driver can be compiled directly into the kernel or compiled into
-a loadable device driver module.
-
-Just use the standard way to configure the driver and compile the Kernel.
-
-
-4.1. Compiling the Driver to Support Rx DMA
--------------------------------------------
-
-The compile-time optionality for DMA was removed in the 2.3 kernel
-series.  DMA support is now unconditionally part of the driver.  It is
-enabled by the 'use_dma=1' module option.
-
-
-5. Testing and Troubleshooting
-==============================
-
-5.1. Known Defects and Limitations
-----------------------------------
-
-Refer to the RELEASE.TXT file distributed as part of this archive for a list of
-known defects, driver limitations, and work arounds.
-
-
-5.2. Testing the Adapter
-------------------------
-
-Once the adapter has been installed and configured, the diagnostic option of
-the CS8900/20 Setup Utility can be used to test the functionality of the
-adapter and its network connection.  Use the diagnostics 'Self Test' option to
-test the functionality of the adapter with the hardware configuration you have
-assigned. You can use the diagnostics 'Network Test' to test the ability of the
-adapter to communicate across the Ethernet with another PC equipped with a
-CS8900/20-based adapter card (it must also be running the CS8900/20 Setup
-Utility).
-
-.. note::
-
-	 The Setup Utility's diagnostics are designed to run in a
-	 DOS-only operating system environment.  DO NOT run the diagnostics
-	 from a DOS or command prompt session under Windows 95, Windows NT,
-	 OS/2, or other operating system.
-
-To run the diagnostics tests on the CS8900/20 adapter:
-
-   1.  Boot DOS on the PC and start the CS8900/20 Setup Utility.
-
-   2.  The adapter's current configuration is displayed.  Hit the ENTER key to
-       get to the main menu.
-
-   4.  Select 'Diagnostics' (ALT-G) from the main menu.
-       * Select 'Self-Test' to test the adapter's basic functionality.
-       * Select 'Network Test' to test the network connection and cabling.
-
-
-5.2.1. Diagnostic Self-test
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The diagnostic self-test checks the adapter's basic functionality as well as
-its ability to communicate across the ISA bus based on the system resources
-assigned during hardware configuration.  The following tests are performed:
-
-   * IO Register Read/Write Test
-
-     The IO Register Read/Write test insures that the CS8900/20 can be
-     accessed in IO mode, and that the IO base address is correct.
-
-   * Shared Memory Test
-
-     The Shared Memory test insures the CS8900/20 can be accessed in memory
-     mode and that the range of memory addresses assigned does not conflict
-     with other devices in the system.
-
-   * Interrupt Test
-
-     The Interrupt test insures there are no conflicts with the assigned IRQ
-     signal.
-
-   * EEPROM Test
-
-     The EEPROM test insures the EEPROM can be read.
-
-   * Chip RAM Test
-
-     The Chip RAM test insures the 4K of memory internal to the CS8900/20 is
-     working properly.
-
-   * Internal Loop-back Test
-
-     The Internal Loop Back test insures the adapter's transmitter and
-     receiver are operating properly.  If this test fails, make sure the
-     adapter's cable is connected to the network (check for LED activity for
-     example).
-
-   * Boot PROM Test
-
-     The Boot PROM  test insures the Boot PROM is present, and can be read.
-     Failure indicates the Boot PROM  was not successfully read due to a
-     hardware problem or due to a conflicts on the Boot PROM address
-     assignment. (Test only applies if the adapter is configured to use the
-     Boot PROM option.)
-
-Failure of a test item indicates a possible system resource conflict with
-another device on the ISA bus.  In this case, you should use the Manual Setup
-option to reconfigure the adapter by selecting a different value for the system
-resource that failed.
-
-
-5.2.2. Diagnostic Network Test
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The Diagnostic Network Test verifies a working network connection by
-transferring data between two CS8900/20 adapters installed in different PCs
-on the same network. (Note: the diagnostic network test should not be run
-between two nodes across a router.)
-
-This test requires that each of the two PCs have a CS8900/20-based adapter
-installed and have the CS8900/20 Setup Utility running.  The first PC is
-configured as a Responder and the other PC is configured as an Initiator.
-Once the Initiator is started, it sends data frames to the Responder which
-returns the frames to the Initiator.
-
-The total number of frames received and transmitted are displayed on the
-Initiator's display, along with a count of the number of frames received and
-transmitted OK or in error.  The test can be terminated anytime by the user at
-either PC.
-
-To setup the Diagnostic Network Test:
-
-    1.  Select a PC with a CS8900/20-based adapter and a known working network
-	connection to act as the Responder.  Run the CS8900/20 Setup Utility
-	and select 'Diagnostics -> Network Test -> Responder' from the main
-	menu.  Hit ENTER to start the Responder.
-
-    2.  Return to the PC with the CS8900/20-based adapter you want to test and
-	start the CS8900/20 Setup Utility.
-
-    3.  From the main menu, Select 'Diagnostic -> Network Test -> Initiator'.
-	Hit ENTER to start the test.
-
-You may stop the test on the Initiator at any time while allowing the Responder
-to continue running.  In this manner, you can move to additional PCs and test
-them by starting the Initiator on another PC without having to stop/start the
-Responder.
-
-
-
-5.3. Using the Adapter's LEDs
------------------------------
-
-The 2 and 3-media adapters have two LEDs visible on the back end of the board
-located near the 10Base-T connector.
-
-Link Integrity LED: A "steady" ON of the green LED indicates a valid 10Base-T
-connection.  (Only applies to 10Base-T.  The green LED has no significance for
-a 10Base-2 or AUI connection.)
-
-TX/RX LED: The yellow LED lights briefly each time the adapter transmits or
-receives data. (The yellow LED will appear to "flicker" on a typical network.)
-
-
-5.4. Resolving I/O Conflicts
-----------------------------
-
-An IO conflict occurs when two or more adapter use the same ISA resource (IO
-address, memory address or IRQ).  You can usually detect an IO conflict in one
-of four ways after installing and or configuring the CS8900/20-based adapter:
-
-    1.  The system does not boot properly (or at all).
-
-    2.  The driver cannot communicate with the adapter, reporting an "Adapter
-	not found" error message.
-
-    3.  You cannot connect to the network or the driver will not load.
-
-    4.  If you have configured the adapter to run in memory mode but the driver
-	reports it is using IO mode when loading, this is an indication of a
-	memory address conflict.
-
-If an IO conflict occurs, run the CS8900/20 Setup Utility and perform a
-diagnostic self-test.  Normally, the ISA resource in conflict will fail the
-self-test.  If so, reconfigure the adapter selecting another choice for the
-resource in conflict.  Run the diagnostics again to check for further IO
-conflicts.
-
-In some cases, such as when the PC will not boot, it may be necessary to remove
-the adapter and reconfigure it by installing it in another PC to run the
-CS8900/20 Setup Utility.  Once reinstalled in the target system, run the
-diagnostics self-test to ensure the new configuration is free of conflicts
-before loading the driver again.
-
-When manually configuring the adapter, keep in mind the typical ISA system
-resource usage as indicated in the tables below.

-DM9000 Network driver
-=====================
-
-Copyright 2008 Simtec Electronics,
-
-	  Ben Dooks <ben@simtec.co.uk> <ben-linux@fluff.org>
-
-
-Introduction
-------------
-
-This file describes how to use the DM9000 platform-device based network driver
-that is contained in the files drivers/net/dm9000.c and drivers/net/dm9000.h.
-
-The driver supports three DM9000 variants, the DM9000E which is the first chip
-supported as well as the newer DM9000A and DM9000B devices. It is currently
-maintained and tested by Ben Dooks, who should be CC: to any patches for this
-driver.
-
-
-Defining the platform device
-----------------------------
-
-The minimum set of resources attached to the platform device are as follows:
-
-    1) The physical address of the address register
-    2) The physical address of the data register
-    3) The IRQ line the device's interrupt pin is connected to.
-
-These resources should be specified in that order, as the ordering of the
-two address regions is important (the driver expects these to be address
-and then data).
-
-An example from arch/arm/mach-s3c2410/mach-bast.c is::
-
-  static struct resource bast_dm9k_resource[] = {
-	[0] = {
-		.start = S3C2410_CS5 + BAST_PA_DM9000,
-		.end   = S3C2410_CS5 + BAST_PA_DM9000 + 3,
-		.flags = IORESOURCE_MEM,
-	},
-	[1] = {
-		.start = S3C2410_CS5 + BAST_PA_DM9000 + 0x40,
-		.end   = S3C2410_CS5 + BAST_PA_DM9000 + 0x40 + 0x3f,
-		.flags = IORESOURCE_MEM,
-	},
-	[2] = {
-		.start = IRQ_DM9000,
-		.end   = IRQ_DM9000,
-		.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,
-	}
-  };
-
-  static struct platform_device bast_device_dm9k = {
-	.name		= "dm9000",
-	.id		= 0,
-	.num_resources	= ARRAY_SIZE(bast_dm9k_resource),
-	.resource	= bast_dm9k_resource,
-  };
-
-Note the setting of the IRQ trigger flag in bast_dm9k_resource[2].flags,
-as this will generate a warning if it is not present. The trigger from
-the flags field will be passed to request_irq() when registering the IRQ
-handler to ensure that the IRQ is setup correctly.
-
-This shows a typical platform device, without the optional configuration
-platform data supplied. The next example uses the same resources, but adds
-the optional platform data to pass extra configuration data::
-
-  static struct dm9000_plat_data bast_dm9k_platdata = {
-	.flags		= DM9000_PLATF_16BITONLY,
-  };
-
-  static struct platform_device bast_device_dm9k = {
-	.name		= "dm9000",
-	.id		= 0,
-	.num_resources	= ARRAY_SIZE(bast_dm9k_resource),
-	.resource	= bast_dm9k_resource,
-	.dev		= {
-		.platform_data = &bast_dm9k_platdata,
-	}
-  };
-
-The platform data is defined in include/linux/dm9000.h and described below.
-
-
-Platform data
--------------
-
-Extra platform data for the DM9000 can describe the IO bus width to the
-device, whether or not an external PHY is attached to the device and
-the availability of an external configuration EEPROM.
-
-The flags for the platform data .flags field are as follows:
-
-DM9000_PLATF_8BITONLY
-
-	The IO should be done with 8bit operations.
-
-DM9000_PLATF_16BITONLY
-
-	The IO should be done with 16bit operations.
-
-DM9000_PLATF_32BITONLY
-
-	The IO should be done with 32bit operations.
-
-DM9000_PLATF_EXT_PHY
-
-	The chip is connected to an external PHY.
-
-DM9000_PLATF_NO_EEPROM
-
-	This can be used to signify that the board does not have an
-	EEPROM, or that the EEPROM should be hidden from the user.
-
-DM9000_PLATF_SIMPLE_PHY
-
-	Switch to using the simpler PHY polling method which does not
-	try and read the MII PHY state regularly. This is only available
-	when using the internal PHY. See the section on link state polling
-	for more information.
-
-	The config symbol DM9000_FORCE_SIMPLE_PHY_POLL, Kconfig entry
-	"Force simple NSR based PHY polling" allows this flag to be
-	forced on at build time.
-
-
-PHY Link state polling
-----------------------
-
-The driver keeps track of the link state and informs the network core
-about link (carrier) availability. This is managed by several methods
-depending on the version of the chip and on which PHY is being used.
-
-For the internal PHY, the original (and currently default) method is
-to read the MII state, either when the status changes if we have the
-necessary interrupt support in the chip or every two seconds via a
-periodic timer.
-
-To reduce the overhead for the internal PHY, there is now the option
-of using the DM9000_FORCE_SIMPLE_PHY_POLL config, or DM9000_PLATF_SIMPLE_PHY
-platform data option to read the summary information without the
-expensive MII accesses. This method is faster, but does not print
-as much information.
-
-When using an external PHY, the driver currently has to poll the MII
-link status as there is no method for getting an interrupt on link change.
-
-
-DM9000A / DM9000B
------------------
-
-These chips are functionally similar to the DM9000E and are supported easily
-by the same driver. The features are:
-
-   1) Interrupt on internal PHY state change. This means that the periodic
-      polling of the PHY status may be disabled on these devices when using
-      the internal PHY.
-
-   2) TCP/UDP checksum offloading, which the driver does not currently support.
-
-
-ethtool
--------
-
-The driver supports the ethtool interface for access to the driver
-state information, the PHY state and the EEPROM.

-===================================
-DEC EtherWORKS Ethernet De4x5 cards
-===================================
-
-    Originally,   this  driver  was    written  for the  Digital   Equipment
-    Corporation series of EtherWORKS Ethernet cards:
-
-	 - DE425 TP/COAX EISA
-	 - DE434 TP PCI
-	 - DE435 TP/COAX/AUI PCI
-	 - DE450 TP/COAX/AUI PCI
-	 - DE500 10/100 PCI Fasternet
-
-    but it  will  now attempt  to  support all  cards which   conform to the
-    Digital Semiconductor   SROM   Specification.    The  driver   currently
-    recognises the following chips:
-
-	 - DC21040  (no SROM)
-	 - DC21041[A]
-	 - DC21140[A]
-	 - DC21142
-	 - DC21143
-
-    So far the driver is known to work with the following cards:
-
-	 - KINGSTON
-	 - Linksys
-	 - ZNYX342
-	 - SMC8432
-	 - SMC9332 (w/new SROM)
-	 - ZNYX31[45]
-	 - ZNYX346 10/100 4 port (can act as a 10/100 bridge!)
-
-    The driver has been tested on a relatively busy network using the DE425,
-    DE434, DE435 and DE500 cards and benchmarked with 'ttcp': it transferred
-    16M of data to a DECstation 5000/200 as follows::
-
-		  TCP           UDP
-	       TX     RX     TX     RX
-      DE425   1030k  997k   1170k  1128k
-      DE434   1063k  995k   1170k  1125k
-      DE435   1063k  995k   1170k  1125k
-      DE500   1063k  998k   1170k  1125k  in 10Mb/s mode
-
-    All  values are typical (in   kBytes/sec) from a  sample  of 4 for  each
-    measurement. Their error is +/-20k on a quiet (private) network and also
-    depend on what load the CPU has.
-
-----------------------------------------------------------------------------
-
-    The ability to load this  driver as a loadable  module has been included
-    and used extensively  during the driver development  (to save those long
-    reboot sequences).  Loadable module support  under PCI and EISA has been
-    achieved by letting the driver autoprobe as if it were compiled into the
-    kernel. Do make sure  you're not sharing  interrupts with anything  that
-    cannot accommodate  interrupt  sharing!
-
-    To utilise this ability, you have to do 8 things:
-
-    0) have a copy of the loadable modules code installed on your system.
-    1) copy de4x5.c from the  /linux/drivers/net directory to your favourite
-       temporary directory.
-    2) for fixed  autoprobes (not  recommended),  edit the source code  near
-       line 5594 to reflect the I/O address  you're using, or assign these when
-       loading by::
-
-		   insmod de4x5 io=0xghh           where g = bus number
-							hh = device number
-
-       .. note::
-
-	   autoprobing for modules is now supported by default. You may just
-	   use::
-
-		   insmod de4x5
-
-	   to load all available boards. For a specific board, still use
-	   the 'io=?' above.
-    3) compile  de4x5.c, but include -DMODULE in  the command line to ensure
-       that the correct bits are compiled (see end of source code).
-    4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
-       kernel with the de4x5 configuration turned off and reboot.
-    5) insmod de4x5 [io=0xghh]
-    6) run the net startup bits for your new eth?? interface(s) manually
-       (usually /etc/rc.inet[12] at boot time).
-    7) enjoy!
-
-    To unload a module, turn off the associated interface(s)
-    'ifconfig eth?? down' then 'rmmod de4x5'.
-
-    Automedia detection is included so that in  principle you can disconnect
-    from, e.g.  TP, reconnect  to BNC  and  things will still work  (after a
-    pause while the   driver figures out   where its media went).  My tests
-    using ping showed that it appears to work....
-
-    By  default,  the driver will  now   autodetect any  DECchip based card.
-    Should you have a need to restrict the driver to DIGITAL only cards, you
-    can compile with a  DEC_ONLY define, or if  loading as a module, use the
-    'dec_only=1'  parameter.
-
-    I've changed the timing routines to  use the kernel timer and scheduling
-    functions  so that the  hangs  and other assorted problems that occurred
-    while autosensing the  media  should be gone.  A  bonus  for the DC21040
-    auto  media sense algorithm is  that it can now  use one that is more in
-    line with the  rest (the DC21040  chip doesn't  have a hardware  timer).
-    The downside is the 1 'jiffies' (10ms) resolution.
-
-    IEEE 802.3u MII interface code has  been added in anticipation that some
-    products may use it in the future.
-
-    The SMC9332 card  has a non-compliant SROM  which needs fixing -  I have
-    patched this  driver to detect it  because the SROM format used complies
-    to a previous DEC-STD format.
-
-    I have removed the buffer copies needed for receive on Intels.  I cannot
-    remove them for   Alphas since  the  Tulip hardware   only does longword
-    aligned  DMA transfers  and  the  Alphas get   alignment traps with  non
-    longword aligned data copies (which makes them really slow). No comment.
-
-    I  have added SROM decoding  routines to make this  driver work with any
-    card that  supports the Digital  Semiconductor SROM spec. This will help
-    all  cards running the dc2114x  series chips in particular.  Cards using
-    the dc2104x  chips should run correctly with  the basic  driver.  I'm in
-    debt to <mjacob@feral.com> for the  testing and feedback that helped get
-    this feature working.  So far we have  tested KINGSTON, SMC8432, SMC9332
-    (with the latest SROM complying  with the SROM spec  V3: their first was
-    broken), ZNYX342  and  LinkSys. ZNYX314 (dual  21041  MAC) and  ZNYX 315
-    (quad 21041 MAC)  cards also  appear  to work despite their  incorrectly
-    wired IRQs.
-
-    I have added a temporary fix for interrupt problems when some SCSI cards
-    share the same interrupt as the DECchip based  cards. The problem occurs
-    because  the SCSI card wants to  grab the interrupt  as a fast interrupt
-    (runs the   service routine with interrupts turned   off) vs.  this card
-    which really needs to run the service routine with interrupts turned on.
-    This driver will  now   add the interrupt service   routine  as  a  fast
-    interrupt if it   is bounced from the   slow interrupt.  THIS IS NOT   A
-    RECOMMENDED WAY TO RUN THE DRIVER  and has been done  for a limited time
-    until  people   sort  out their  compatibility    issues and the  kernel
-    interrupt  service code  is  fixed.   YOU  SHOULD SEPARATE OUT  THE FAST
-    INTERRUPT CARDS FROM THE SLOW INTERRUPT CARDS to ensure that they do not
-    run on the same interrupt. PCMCIA/CardBus is another can of worms...
-
-    Finally, I think  I have really  fixed  the module  loading problem with
-    more than one DECchip based  card.  As a  side effect, I don't mess with
-    the  device structure any  more which means that  if more than 1 card in
-    2.0.x is    installed (4  in   2.1.x),  the  user   will have   to  edit
-    linux/drivers/net/Space.c  to make room for  them. Hence, module loading
-    is  the preferred way to use   this driver, since  it  doesn't have this
-    limitation.
-
-    Where SROM media  detection is used and  full duplex is specified in the
-    SROM,  the feature is  ignored unless  lp->params.fdx  is set at compile
-    time  OR during  a   module load  (insmod  de4x5   args='eth??:fdx' [see
-    below]).  This is because there  is no way  to automatically detect full
-    duplex   links  except through   autonegotiation.    When I  include the
-    autonegotiation feature in  the SROM autoconf  code, this detection will
-    occur automatically for that case.
-
-    Command line  arguments are  now allowed, similar to  passing  arguments
-    through LILO. This will allow a per adapter board set  up of full duplex
-    and media. The only lexical constraints are:  the board name (dev->name)
-    appears in  the list before its parameters.  The list of parameters ends
-    either at the end of the parameter list or with another board name.  The
-    following parameters are allowed:
-
-	    =========  ===============================================
-	    fdx        for full duplex
-	    autosense  to set the media/speed; with the following
-		       sub-parameters:
-		       TP, TP_NW, BNC, AUI, BNC_AUI, 100Mb, 10Mb, AUTO
-	    =========  ===============================================
-
-    Case sensitivity is important  for  the sub-parameters. They *must*   be
-    upper case. Examples::
-
-	insmod de4x5 args='eth1:fdx autosense=BNC eth0:autosense=100Mb'.
-
-    For a compiled in driver, in linux/drivers/net/CONFIG, place e.g.::
-
-	DE4X5_OPTS = -DDE4X5_PARM='"eth0:fdx autosense=AUI eth2:autosense=TP"'
-
-    Yes,  I know full duplex  isn't permissible on BNC  or AUI; they're just
-    examples. By default, full duplex is turned  off and AUTO is the default
-    autosense setting. In  reality, I expect only the  full duplex option to
-    be used. Note the use of single quotes in the two examples above and the
-    lack of commas to separate items.

-	dmfe: Davicom DM9xxx net driver, version 1.36.4 (2002-01-17)
-
-If you compiled this driver as a module, you have to load it on boot.You can load it with command::
-
-	insmod dmfe
-
-This way it will autodetect the device mode.This is the suggested way to load the module.Or you can pass
-a mode= setting to module while loading, like::
-
-	insmod dmfe mode=0 # Force 10M Half Duplex
-	insmod dmfe mode=1 # Force 100M Half Duplex
-	insmod dmfe mode=4 # Force 10M Full Duplex
-	insmod dmfe mode=5 # Force 100M Full Duplex
-
-Next you should configure your network interface with a command similar to::
-
-	ifconfig eth0 172.22.3.18
-		      ^^^^^^^^^^^
-		     Your IP Address
-
-Then you may have to modify the default routing table with command::
-
-	route add default eth0
-
-
-Now your ethernet card should be up and running.

-   located at /etc/sysconfig/network-scripts or create it manually.
-
-   [see - Configuration Script Sample]
-8. Driver will automatically load and configure at next boot time.
-
-Compiling the Driver
-====================
-In Linux, NIC drivers are most commonly configured as loadable modules.
-The approach of building a monolithic kernel has become obsolete. The driver
-can be compiled as part of a monolithic kernel, but is strongly discouraged.
-The remainder of this section assumes the driver is built as a loadable module.
-In the Linux environment, it is a good idea to rebuild the driver from the
-source instead of relying on a precompiled version. This approach provides
-better reliability since a precompiled driver might depend on libraries or
-kernel features that are not present in a given Linux installation.
-
-The 3 files necessary to build Linux device driver are dl2k.c, dl2k.h and
-Makefile. To compile, the Linux installation must include the gcc compiler,
-the kernel source, and the kernel headers. The Linux driver supports Linux
-Kernels 2.4.7. Copy the files to a directory and enter the following command
-to compile and link the driver:
-
-CD-ROM drive
-------------
-
-::
-
-    [root@XXX /] mkdir cdrom
-    [root@XXX /] mount -r -t iso9660 -o conv=auto /dev/cdrom /cdrom
-    [root@XXX /] cd root
-    [root@XXX /root] mkdir dl2k
-    [root@XXX /root] cd dl2k
-    [root@XXX dl2k] cp /cdrom/linux/dl2k.tgz /root/dl2k
-    [root@XXX dl2k] tar xfvz dl2k.tgz
-    [root@XXX dl2k] make all
-
-Floppy disc drive
------------------
-
-::
-
-    [root@XXX /] cd root
-    [root@XXX /root] mkdir dl2k
-    [root@XXX /root] cd dl2k
-    [root@XXX dl2k] mcopy a:/linux/dl2k.tgz /root/dl2k
-    [root@XXX dl2k] tar xfvz dl2k.tgz
-    [root@XXX dl2k] make all
-
-Installing the Driver
-=====================
-
-Manual Installation
--------------------
-
-  Once the driver has been compiled, it must be loaded, enabled, and bound
-  to a protocol stack in order to establish network connectivity. To load a
-  module enter the command::
-
-    insmod dl2k.o
-
-  or::
-
-    insmod dl2k.o <optional parameter>	; add parameter
-
----------------------------------------------------------
-
-  example::
-
-    insmod dl2k.o media=100mbps_hd
-
-   or::
-
-    insmod dl2k.o media=3
-
-   or::
-
-    insmod dl2k.o media=3,2	; for 2 cards
-
----------------------------------------------------------
-
-  Please reference the list of the command line parameters supported by
-  the Linux device driver below.
-
-  The insmod command only loads the driver and gives it a name of the form
-  eth0, eth1, etc. To bring the NIC into an operational state,
-  it is necessary to issue the following command::
-
-    ifconfig eth0 up
-
-  Finally, to bind the driver to the active protocol (e.g., TCP/IP with
-  Linux), enter the following command::
-
-    ifup eth0
-
-  Note that this is meaningful only if the system can find a configuration
-  script that contains the necessary network information. A sample will be
-  given in the next paragraph.
-
-  The commands to unload a driver are as follows::
-
-    ifdown eth0
-    ifconfig eth0 down
-    rmmod dl2k.o
-
-  The following are the commands to list the currently loaded modules and
-  to see the current network configuration::
-
-    lsmod
-    ifconfig
-
-
-Automated Installation
-----------------------
-  This section describes how to install the driver such that it is
-  automatically loaded and configured at boot time. The following description
-  is based on a Red Hat 6.0/7.0 distribution, but it can easily be ported to
-  other distributions as well.
-
-Red Hat v6.x/v7.x
------------------
-  1. Copy dl2k.o to the network modules directory, typically
-     /lib/modules/2.x.x-xx/net or /lib/modules/2.x.x/kernel/drivers/net.
-  2. Locate the boot module configuration file, most commonly in the
-     /etc/modprobe.d/ directory. Add the following lines::
-
-	alias ethx dl2k
-	options dl2k <optional parameters>
-
-     where ethx will be eth0 if the NIC is the only ethernet adapter, eth1 if
-     one other ethernet adapter is installed, etc. Refer to the table in the
-     previous section for the list of optional parameters.
-  3. Locate the network configuration scripts, normally the
-     /etc/sysconfig/network-scripts directory, and create a configuration
-     script named ifcfg-ethx that contains network information.
-  4. Note that for most Linux distributions, Red Hat included, a configuration
-     utility with a graphical user interface is provided to perform steps 2
-     and 3 above.
-
-
-Parameter Description
-=====================
-You can install this driver without any additional parameter. However, if you
-are going to have extensive functions then it is necessary to set extra
-parameter. Below is a list of the command line parameters supported by the
-Linux device
-driver.
-
-
-===============================   ==============================================
-mtu=packet_size			  Specifies the maximum packet size. default
-				  is 1500.
-
-media=media_type		  Specifies the media type the NIC operates at.
-				  autosense	Autosensing active media.
-
-				  ===========	=========================
-				  10mbps_hd	10Mbps half duplex.
-				  10mbps_fd	10Mbps full duplex.
-				  100mbps_hd	100Mbps half duplex.
-				  100mbps_fd	100Mbps full duplex.
-				  1000mbps_fd	1000Mbps full duplex.
-				  1000mbps_hd	1000Mbps half duplex.
-				  0		Autosensing active media.
-				  1		10Mbps half duplex.
-				  2		10Mbps full duplex.
-				  3		100Mbps half duplex.
-				  4		100Mbps full duplex.
-				  5          	1000Mbps half duplex.
-				  6          	1000Mbps full duplex.
-				  ===========	=========================
-
-				  By default, the NIC operates at autosense.
-				  1000mbps_fd and 1000mbps_hd types are only
-				  available for fiber adapter.
-
-vlan=n				  Specifies the VLAN ID. If vlan=0, the
-				  Virtual Local Area Network (VLAN) function is
-				  disable.
-
-jumbo=[0|1]			  Specifies the jumbo frame support. If jumbo=1,
-				  the NIC accept jumbo frames. By default, this
-				  function is disabled.
-				  Jumbo frame usually improve the performance
-				  int gigabit.
-				  This feature need jumbo frame compatible
-				  remote.
-
-rx_coalesce=m			  Number of rx frame handled each interrupt.
-rx_timeout=n			  Rx DMA wait time for an interrupt.
-				  If set rx_coalesce > 0, hardware only assert
-				  an interrupt for m frames. Hardware won't
-				  assert rx interrupt until m frames received or
-				  reach timeout of n * 640 nano seconds.
-				  Set proper rx_coalesce and rx_timeout can
-				  reduce congestion collapse and overload which
-				  has been a bottleneck for high speed network.
-
-				  For example, rx_coalesce=10 rx_timeout=800.
-				  that is, hardware assert only 1 interrupt
-				  for 10 frames received or timeout of 512 us.
-
-tx_coalesce=n			  Number of tx frame handled each interrupt.
-				  Set n > 1 can reduce the interrupts
-				  congestion usually lower performance of
-				  high speed network card. Default is 16.
-
-tx_flow=[1|0]			  Specifies the Tx flow control. If tx_flow=0,
-				  the Tx flow control disable else driver
-				  autodetect.
-rx_flow=[1|0]			  Specifies the Rx flow control. If rx_flow=0,
-				  the Rx flow control enable else driver
-				  autodetect.
-===============================   ==============================================

-
-Configuration Script Sample
-===========================
-Here is a sample of a simple configuration script::
-
-    DEVICE=eth0
-    USERCTL=no
-    ONBOOT=yes
-    POOTPROTO=none
-    BROADCAST=207.200.5.255
-    NETWORK=207.200.5.0
-    NETMASK=255.255.255.0
-    IPADDR=207.200.5.2
-
-
-Troubleshooting
-===============
-Q1. Source files contain ^ M behind every line.
-
-    Make sure all files are Unix file format (no LF). Try the following
-    shell command to convert files::
-
-	cat dl2k.c | col -b > dl2k.tmp
-	mv dl2k.tmp dl2k.c
-
-    OR::
-
-	cat dl2k.c | tr -d "\r" > dl2k.tmp
-	mv dl2k.tmp dl2k.c
-
-Q2: Could not find header files (``*.h``)?
-
-    To compile the driver, you need kernel header files. After
-    installing the kernel source, the header files are usually located in
-    /usr/src/linux/include, which is the default include directory configured
-    in Makefile. For some distributions, there is a copy of header files in
-    /usr/src/include/linux and /usr/src/include/asm, that you can change the
-    INCLUDEDIR in Makefile to /usr/include without installing kernel source.
-
-    Note that RH 7.0 didn't provide correct header files in /usr/include,
-    including those files will make a wrong version driver.

+Linux and the 3Com EtherLink III Series Ethercards (driver v1.18c and higher)
+=============================================================================
+
+This file contains the instructions and caveats for v1.18c and higher versions
+of the 3c509 driver. You should not use the driver without reading this file.
+
+release 1.0
+
+28 February 2002

+Current maintainer (corrections to):
+  David Ruggiero <jdr@farfalle.com>
+
+Introduction
+============
+
+The following are notes and information on using the 3Com EtherLink III series
+ethercards in Linux. These cards are commonly known by the most widely-used
+card's 3Com model number, 3c509. They are all 10mb/s ISA-bus cards and shouldn't
+be (but sometimes are) confused with the similarly-numbered PCI-bus "3c905"
+(aka "Vortex" or "Boomerang") series.  Kernel support for the 3c509 family is
+provided by the module 3c509.c, which has code to support all of the following
+models:
+
+ - 3c509 (original ISA card)
+ - 3c509B (later revision of the ISA card; supports full-duplex)
+ - 3c589 (PCMCIA)
+ - 3c589B (later revision of the 3c589; supports full-duplex)
+ - 3c579 (EISA)
+
+Large portions of this documentation were heavily borrowed from the guide
+written the original author of the 3c509 driver, Donald Becker. The master
+copy of that document, which contains notes on older versions of the driver,
+currently resides on Scyld web server: http://www.scyld.com/.
+
+
+Special Driver Features
+=======================
+
+Overriding card settings
+
+The driver allows boot- or load-time overriding of the card's detected IOADDR,
+IRQ, and transceiver settings, although this capability shouldn't generally be
+needed except to enable full-duplex mode (see below). An example of the syntax
+for LILO parameters for doing this::
+
+    ether=10,0x310,3,0x3c509,eth0
+
+This configures the first found 3c509 card for IRQ 10, base I/O 0x310, and
+transceiver type 3 (10base2). The flag "0x3c509" must be set to avoid conflicts
+with other card types when overriding the I/O address. When the driver is
+loaded as a module, only the IRQ may be overridden. For example,
+setting two cards to IRQ10 and IRQ11 is done by using the irq module
+option::
+
+   options 3c509 irq=10,11
+
+
+Full-duplex mode
+================
+
+The v1.18c driver added support for the 3c509B's full-duplex capabilities.
+In order to enable and successfully use full-duplex mode, three conditions
+must be met:
+
+(a) You must have a Etherlink III card model whose hardware supports full-
+duplex operations. Currently, the only members of the 3c509 family that are
+positively known to support full-duplex are the 3c509B (ISA bus) and 3c589B
+(PCMCIA) cards. Cards without the "B" model designation do *not* support
+full-duplex mode; these include the original 3c509 (no "B"), the original
+3c589, the 3c529 (MCA bus), and the 3c579 (EISA bus).
+
+(b) You must be using your card's 10baseT transceiver (i.e., the RJ-45
+connector), not its AUI (thick-net) or 10base2 (thin-net/coax) interfaces.
+AUI and 10base2 network cabling is physically incapable of full-duplex
+operation.
+
+(c) Most importantly, your 3c509B must be connected to a link partner that is
+itself full-duplex capable. This is almost certainly one of two things: a full-
+duplex-capable  Ethernet switch (*not* a hub), or a full-duplex-capable NIC on
+another system that's connected directly to the 3c509B via a crossover cable.
+
+Full-duplex mode can be enabled using 'ethtool'.
+
+.. warning::
+
+  Extremely important caution concerning full-duplex mode
+
+  Understand that the 3c509B's hardware's full-duplex support is much more
+  limited than that provide by more modern network interface cards. Although
+  at the physical layer of the network it fully supports full-duplex operation,
+  the card was designed before the current Ethernet auto-negotiation (N-way)
+  spec was written. This means that the 3c509B family ***cannot and will not
+  auto-negotiate a full-duplex connection with its link partner under any
+  circumstances, no matter how it is initialized***. If the full-duplex mode
+  of the 3c509B is enabled, its link partner will very likely need to be
+  independently _forced_ into full-duplex mode as well; otherwise various nasty
+  failures will occur - at the very least, you'll see massive numbers of packet
+  collisions. This is one of very rare circumstances where disabling auto-
+  negotiation and forcing the duplex mode of a network interface card or switch
+  would ever be necessary or desirable.
+
+
+Available Transceiver Types
+===========================
+
+For versions of the driver v1.18c and above, the available transceiver types are:
+
+== =========================================================================
+0  transceiver type from EEPROM config (normally 10baseT); force half-duplex
+1  AUI (thick-net / DB15 connector)
+2  (undefined)
+3  10base2 (thin-net == coax / BNC connector)
+4  10baseT (RJ-45 connector); force half-duplex mode
+8  transceiver type and duplex mode taken from card's EEPROM config settings
+12 10baseT (RJ-45 connector); force full-duplex mode
+== =========================================================================
+
+Prior to driver version 1.18c, only transceiver codes 0-4 were supported. Note
+that the new transceiver codes 8 and 12 are the *only* ones that will enable
+full-duplex mode, no matter what the card's detected EEPROM settings might be.
+This insured that merely upgrading the driver from an earlier version would
+never automatically enable full-duplex mode in an existing installation;
+it must always be explicitly enabled via one of these code in order to be
+activated.
+
+The transceiver type can be changed using 'ethtool'.
+
+
+Interpretation of error messages and common problems
+----------------------------------------------------
+
+Error Messages
+^^^^^^^^^^^^^^
+
+eth0: Infinite loop in interrupt, status 2011.
+These are "mostly harmless" message indicating that the driver had too much
+work during that interrupt cycle. With a status of 0x2011 you are receiving
+packets faster than they can be removed from the card. This should be rare
+or impossible in normal operation. Possible causes of this error report are:
+
+   - a "green" mode enabled that slows the processor down when there is no
+     keyboard activity.
+
+   - some other device or device driver hogging the bus or disabling interrupts.
+     Check /proc/interrupts for excessive interrupt counts. The timer tick
+     interrupt should always be incrementing faster than the others.
+
+No received packets
+^^^^^^^^^^^^^^^^^^^
+
+If a 3c509, 3c562 or 3c589 can successfully transmit packets, but never
+receives packets (as reported by /proc/net/dev or 'ifconfig') you likely
+have an interrupt line problem. Check /proc/interrupts to verify that the
+card is actually generating interrupts. If the interrupt count is not
+increasing you likely have a physical conflict with two devices trying to
+use the same ISA IRQ line. The common conflict is with a sound card on IRQ10
+or IRQ5, and the easiest solution is to move the 3c509 to a different
+interrupt line. If the device is receiving packets but 'ping' doesn't work,
+you have a routing problem.
+
+Tx Carrier Errors Reported in /proc/net/dev
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+
+If an EtherLink III appears to transmit packets, but the "Tx carrier errors"
+field in /proc/net/dev increments as quickly as the Tx packet count, you
+likely have an unterminated network or the incorrect media transceiver selected.
+
+3c509B card is not detected on machines with an ISA PnP BIOS.
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+While the updated driver works with most PnP BIOS programs, it does not work
+with all. This can be fixed by disabling PnP support using the 3Com-supplied
+setup program.
+
+3c509 card is not detected on overclocked machines
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Increase the delay time in id_read_eeprom() from the current value, 500,
+to an absurdly high value, such as 5000.
+
+
+Decoding Status and Error Messages
+----------------------------------
+
+
+The bits in the main status register are:
+
+=====	======================================
+value 	description
+=====	======================================
+0x01 	Interrupt latch
+0x02 	Tx overrun, or Rx underrun
+0x04 	Tx complete
+0x08 	Tx FIFO room available
+0x10 	A complete Rx packet has arrived
+0x20 	A Rx packet has started to arrive
+0x40 	The driver has requested an interrupt
+0x80 	Statistics counter nearly full
+=====	======================================
+
+The bits in the transmit (Tx) status word are:
+
+=====	============================================
+value	description
+=====	============================================
+0x02	Out-of-window collision.
+0x04	Status stack overflow (normally impossible).
+0x08	16 collisions.
+0x10	Tx underrun (not enough PCI bus bandwidth).
+0x20	Tx jabber.
+0x40	Tx interrupt requested.
+0x80	Status is valid (this should always be set).
+=====	============================================
+
+
+When a transmit error occurs the driver produces a status message such as::
+
+   eth0: Transmit error, Tx status register 82
+
+The two values typically seen here are:
+
+0x82
+^^^^
+
+Out of window collision. This typically occurs when some other Ethernet
+host is incorrectly set to full duplex on a half duplex network.
+
+0x88
+^^^^
+
+16 collisions. This typically occurs when the network is exceptionally busy
+or when another host doesn't correctly back off after a collision. If this
+error is mixed with 0x82 errors it is the result of a host incorrectly set
+to full duplex (see above).
+
+Both of these errors are the result of network problems that should be
+corrected. They do not represent driver malfunction.

+Module parameters
+=================
+
+There are several parameters which may be provided to the driver when
+its module is loaded.  These are usually placed in ``/etc/modprobe.d/*.conf``
+configuration files.  Example::
+
+    options 3c59x debug=3 rx_copybreak=300
+
+If you are using the PCMCIA tools (cardmgr) then the options may be
+placed in /etc/pcmcia/config.opts::
+
+    module "3c59x" opts "debug=3 rx_copybreak=300"
+
+
+The supported parameters are:
+
+debug=N
+
+  Where N is a number from 0 to 7.  Anything above 3 produces a lot
+  of output in your system logs.  debug=1 is default.
+
+options=N1,N2,N3,...
+
+  Each number in the list provides an option to the corresponding
+  network card.  So if you have two 3c905's and you wish to provide
+  them with option 0x204 you would use::
+
+    options=0x204,0x204
+
+  The individual options are composed of a number of bitfields which
+  have the following meanings:
+
+  Possible media type settings
+
+	==	=================================
+	0	10baseT
+	1	10Mbs AUI
+	2	undefined
+	3	10base2 (BNC)
+	4	100base-TX
+	5	100base-FX
+	6	MII (Media Independent Interface)
+	7	Use default setting from EEPROM
+	8       Autonegotiate
+	9       External MII
+	10      Use default setting from EEPROM
+	==	=================================
+
+  When generating a value for the 'options' setting, the above media
+  selection values may be OR'ed (or added to) the following:
+
+  ======  =============================================
+  0x8000  Set driver debugging level to 7
+  0x4000  Set driver debugging level to 2
+  0x0400  Enable Wake-on-LAN
+  0x0200  Force full duplex mode.
+  0x0010  Bus-master enable bit (Old Vortex cards only)
+  ======  =============================================
+
+  For example::
+
+    insmod 3c59x options=0x204
+
+  will force full-duplex 100base-TX, rather than allowing the usual
+  autonegotiation.
+
+global_options=N
+
+  Sets the ``options`` parameter for all 3c59x NICs in the machine.
+  Entries in the ``options`` array above will override any setting of
+  this.
+
+full_duplex=N1,N2,N3...
+
+  Similar to bit 9 of 'options'.  Forces the corresponding card into
+  full-duplex mode.  Please use this in preference to the ``options``
+  parameter.
+
+  In fact, please don't use this at all! You're better off getting
+  autonegotiation working properly.
+
+global_full_duplex=N1
+
+  Sets full duplex mode for all 3c59x NICs in the machine.  Entries
+  in the ``full_duplex`` array above will override any setting of this.
+
+flow_ctrl=N1,N2,N3...
+
+  Use 802.3x MAC-layer flow control.  The 3com cards only support the
+  PAUSE command, which means that they will stop sending packets for a
+  short period if they receive a PAUSE frame from the link partner.
+
+  The driver only allows flow control on a link which is operating in
+  full duplex mode.
+
+  This feature does not appear to work on the 3c905 - only 3c905B and
+  3c905C have been tested.
+
+  The 3com cards appear to only respond to PAUSE frames which are
+  sent to the reserved destination address of 01:80:c2:00:00:01.  They
+  do not honour PAUSE frames which are sent to the station MAC address.
+
+rx_copybreak=M
+
+  The driver preallocates 32 full-sized (1536 byte) network buffers
+  for receiving.  When a packet arrives, the driver has to decide
+  whether to leave the packet in its full-sized buffer, or to allocate
+  a smaller buffer and copy the packet across into it.
+
+  This is a speed/space tradeoff.
+
+  The value of rx_copybreak is used to decide when to make the copy.
+  If the packet size is less than rx_copybreak, the packet is copied.
+  The default value for rx_copybreak is 200 bytes.
+
+max_interrupt_work=N
+
+  The driver's interrupt service routine can handle many receive and
+  transmit packets in a single invocation.  It does this in a loop.
+  The value of max_interrupt_work governs how many times the interrupt
+  service routine will loop.  The default value is 32 loops.  If this
+  is exceeded the interrupt service routine gives up and generates a
+  warning message "eth0: Too much work in interrupt".
+
+hw_checksums=N1,N2,N3,...
+
+  Recent 3com NICs are able to generate IPv4, TCP and UDP checksums
+  in hardware.  Linux has used the Rx checksumming for a long time.
+  The "zero copy" patch which is planned for the 2.4 kernel series
+  allows you to make use of the NIC's DMA scatter/gather and transmit
+  checksumming as well.
+
+  The driver is set up so that, when the zerocopy patch is applied,
+  all Tornado and Cyclone devices will use S/G and Tx checksums.
+
+  This module parameter has been provided so you can override this
+  decision.  If you think that Tx checksums are causing a problem, you
+  may disable the feature with ``hw_checksums=0``.
+
+  If you think your NIC should be performing Tx checksumming and the
+  driver isn't enabling it, you can force the use of hardware Tx
+  checksumming with ``hw_checksums=1``.
+
+  The driver drops a message in the logfiles to indicate whether or
+  not it is using hardware scatter/gather and hardware Tx checksums.
+
+  Scatter/gather and hardware checksums provide considerable
+  performance improvement for the sendfile() system call, but a small
+  decrease in throughput for send().  There is no effect upon receive
+  efficiency.
+
+compaq_ioaddr=N,
+compaq_irq=N,
+compaq_device_id=N
+
+  "Variables to work-around the Compaq PCI BIOS32 problem"....
+
+watchdog=N
+
+  Sets the time duration (in milliseconds) after which the kernel
+  decides that the transmitter has become stuck and needs to be reset.
+  This is mainly for debugging purposes, although it may be advantageous
+  to increase this value on LANs which have very high collision rates.
+  The default value is 5000 (5.0 seconds).
+
+enable_wol=N1,N2,N3,...
+
+  Enable Wake-on-LAN support for the relevant interface.  Donald
+  Becker's ``ether-wake`` application may be used to wake suspended
+  machines.
+
+  Also enables the NIC's power management support.
+
+global_enable_wol=N
+
+  Sets enable_wol mode for all 3c59x NICs in the machine.  Entries in
+  the ``enable_wol`` array above will override any setting of this.
+
+Media selection
+---------------
+
+A number of the older NICs such as the 3c590 and 3c900 series have
+10base2 and AUI interfaces.
+
+Prior to January, 2001 this driver would autoeselect the 10base2 or AUI
+port if it didn't detect activity on the 10baseT port.  It would then
+get stuck on the 10base2 port and a driver reload was necessary to
+switch back to 10baseT.  This behaviour could not be prevented with a
+module option override.
+
+Later (current) versions of the driver _do_ support locking of the
+media type.  So if you load the driver module with
+
+	modprobe 3c59x options=0
+
+it will permanently select the 10baseT port.  Automatic selection of
+other media types does not occur.
+
+
+Transmit error, Tx status register 82
+-------------------------------------
+
+This is a common error which is almost always caused by another host on
+the same network being in full-duplex mode, while this host is in
+half-duplex mode.  You need to find that other host and make it run in
+half-duplex mode or fix this host to run in full-duplex mode.
+
+As a last resort, you can force the 3c59x driver into full-duplex mode
+with
+
+	options 3c59x full_duplex=1
+
+but this has to be viewed as a workaround for broken network gear and
+should only really be used for equipment which cannot autonegotiate.

+
+Autonegotiation notes
+---------------------
+
+  The driver uses a one-minute heartbeat for adapting to changes in
+  the external LAN environment if link is up and 5 seconds if link is down.
+  This means that when, for example, a machine is unplugged from a hubbed
+  10baseT LAN plugged into a  switched 100baseT LAN, the throughput
+  will be quite dreadful for up to sixty seconds.  Be patient.
+
+  Cisco interoperability note from Walter Wong <wcw+@CMU.EDU>:
+
+  On a side note, adding HAS_NWAY seems to share a problem with the
+  Cisco 6509 switch.  Specifically, you need to change the spanning
+  tree parameter for the port the machine is plugged into to 'portfast'
+  mode.  Otherwise, the negotiation fails.  This has been an issue
+  we've noticed for a while but haven't had the time to track down.
+
+  Cisco switches    (Jeff Busch <jbusch@deja.com>)
+
+    My "standard config" for ports to which PC's/servers connect directly::
+
+	interface FastEthernet0/N
+	description machinename
+	load-interval 30
+	spanning-tree portfast
+
+    If autonegotiation is a problem, you may need to specify "speed
+    100" and "duplex full" as well (or "speed 10" and "duplex half").
+
+    WARNING: DO NOT hook up hubs/switches/bridges to these
+    specially-configured ports! The switch will become very confused.
+
+
+Reporting and diagnosing problems
+---------------------------------
+
+Maintainers find that accurate and complete problem reports are
+invaluable in resolving driver problems.  We are frequently not able to
+reproduce problems and must rely on your patience and efforts to get to
+the bottom of the problem.
+
+If you believe you have a driver problem here are some of the
+steps you should take:
+
+- Is it really a driver problem?
+
+   Eliminate some variables: try different cards, different
+   computers, different cables, different ports on the switch/hub,
+   different versions of the kernel or of the driver, etc.
+
+- OK, it's a driver problem.
+
+   You need to generate a report.  Typically this is an email to the
+   maintainer and/or netdev@vger.kernel.org.  The maintainer's
+   email address will be in the driver source or in the MAINTAINERS file.
+
+- The contents of your report will vary a lot depending upon the
+  problem.  If it's a kernel crash then you should refer to the
+  admin-guide/reporting-bugs.rst file.
+
+  But for most problems it is useful to provide the following:
+
+   - Kernel version, driver version
+
+   - A copy of the banner message which the driver generates when
+     it is initialised.  For example:
+
+     eth0: 3Com PCI 3c905C Tornado at 0xa400,  00:50:da:6a:88:f0, IRQ 19
+     8K byte-wide RAM 5:3 Rx:Tx split, autoselect/Autonegotiate interface.
+     MII transceiver found at address 24, status 782d.
+     Enabling bus-master transmits and whole-frame receives.
+
+     NOTE: You must provide the ``debug=2`` modprobe option to generate
+     a full detection message.  Please do this::
+
+	modprobe 3c59x debug=2
+
+   - If it is a PCI device, the relevant output from 'lspci -vx', eg::
+
+       00:09.0 Ethernet controller: 3Com Corporation 3c905C-TX [Fast Etherlink] (rev 74)
+	       Subsystem: 3Com Corporation: Unknown device 9200
+	       Flags: bus master, medium devsel, latency 32, IRQ 19
+	       I/O ports at a400 [size=128]
+	       Memory at db000000 (32-bit, non-prefetchable) [size=128]
+	       Expansion ROM at <unassigned> [disabled] [size=128K]
+	       Capabilities: [dc] Power Management version 2
+       00: b7 10 00 92 07 00 10 02 74 00 00 02 08 20 00 00
+       10: 01 a4 00 00 00 00 00 db 00 00 00 00 00 00 00 00
+       20: 00 00 00 00 00 00 00 00 00 00 00 00 b7 10 00 10
+       30: 00 00 00 00 dc 00 00 00 00 00 00 00 05 01 0a 0a
+
+   - A description of the environment: 10baseT? 100baseT?
+     full/half duplex? switched or hubbed?
+
+   - Any additional module parameters which you may be providing to the driver.
+
+   - Any kernel logs which are produced.  The more the merrier.
+     If this is a large file and you are sending your report to a
+     mailing list, mention that you have the logfile, but don't send
+     it.  If you're reporting direct to the maintainer then just send
+     it.
+
+     To ensure that all kernel logs are available, add the
+     following line to /etc/syslog.conf::
+
+	 kern.* /var/log/messages
+
+     Then restart syslogd with::
+
+	 /etc/rc.d/init.d/syslog restart
+
+     (The above may vary, depending upon which Linux distribution you use).
+
+    - If your problem is reproducible then that's great.  Try the
+      following:
+
+      1) Increase the debug level.  Usually this is done via:
+
+	 a) modprobe driver debug=7
+	 b) In /etc/modprobe.d/driver.conf:
+	    options driver debug=7
+
+      2) Recreate the problem with the higher debug level,
+	 send all logs to the maintainer.
+
+      3) Download you card's diagnostic tool from Donald
+	 Becker's website <http://www.scyld.com/ethercard_diag.html>.
+	 Download mii-diag.c as well.  Build these.
+
+	 a) Run 'vortex-diag -aaee' and 'mii-diag -v' when the card is
+	    working correctly.  Save the output.
+
+	 b) Run the above commands when the card is malfunctioning.  Send
+	    both sets of output.
+
+Finally, please be patient and be prepared to do some work.  You may
+end up working on this problem for a week or more as the maintainer
+asks more questions, asks for more tests, asks for patches to be
+applied, etc.  At the end of it all, the problem may even remain
+unresolved.

+============================================================
+Linux kernel driver for Elastic Network Adapter (ENA) family
+============================================================
+
+Overview
+========
+
+ENA is a networking interface designed to make good use of modern CPU
+features and system architectures.
+
+The ENA device exposes a lightweight management interface with a
+minimal set of memory mapped registers and extendable command set
+through an Admin Queue.
+
+The driver supports a range of ENA devices, is link-speed independent
+(i.e., the same driver is used for 10GbE, 25GbE, 40GbE, etc.), and has
+a negotiated and extendable feature set.
+
+Some ENA devices support SR-IOV. This driver is used for both the
+SR-IOV Physical Function (PF) and Virtual Function (VF) devices.
+
+ENA devices enable high speed and low overhead network traffic
+processing by providing multiple Tx/Rx queue pairs (the maximum number
+is advertised by the device via the Admin Queue), a dedicated MSI-X
+interrupt vector per Tx/Rx queue pair, adaptive interrupt moderation,
+and CPU cacheline optimized data placement.
+
+The ENA driver supports industry standard TCP/IP offload features such
+as checksum offload and TCP transmit segmentation offload (TSO).
+Receive-side scaling (RSS) is supported for multi-core scaling.
+
+The ENA driver and its corresponding devices implement health
+monitoring mechanisms such as watchdog, enabling the device and driver
+to recover in a manner transparent to the application, as well as
+debug logs.
+
+Some of the ENA devices support a working mode called Low-latency
+Queue (LLQ), which saves several more microseconds.

+
+Management Interface:
+=====================
+
+ENA management interface is exposed by means of:
+
+- PCIe Configuration Space
+- Device Registers
+- Admin Queue (AQ) and Admin Completion Queue (ACQ)
+- Asynchronous Event Notification Queue (AENQ)
+
+ENA device MMIO Registers are accessed only during driver
+initialization and are not involved in further normal device
+operation.
+
+AQ is used for submitting management commands, and the
+results/responses are reported asynchronously through ACQ.
+
+ENA introduces a small set of management commands with room for
+vendor-specific extensions. Most of the management operations are
+framed in a generic Get/Set feature command.
+
+The following admin queue commands are supported:
+
+- Create I/O submission queue
+- Create I/O completion queue
+- Destroy I/O submission queue
+- Destroy I/O completion queue
+- Get feature
+- Set feature
+- Configure AENQ
+- Get statistics
+
+Refer to ena_admin_defs.h for the list of supported Get/Set Feature
+properties.
+
+The Asynchronous Event Notification Queue (AENQ) is a uni-directional
+queue used by the ENA device to send to the driver events that cannot
+be reported using ACQ. AENQ events are subdivided into groups. Each
+group may have multiple syndromes, as shown below
+
+The events are:
+
+	====================	===============
+	Group			Syndrome
+	====================	===============
+	Link state change	**X**
+	Fatal error		**X**
+	Notification		Suspend traffic
+	Notification		Resume traffic
+	Keep-Alive		**X**
+	====================	===============
+
+ACQ and AENQ share the same MSI-X vector.
+
+Keep-Alive is a special mechanism that allows monitoring of the
+device's health. The driver maintains a watchdog (WD) handler which,
+if fired, logs the current state and statistics then resets and
+restarts the ENA device and driver. A Keep-Alive event is delivered by
+the device every second. The driver re-arms the WD upon reception of a
+Keep-Alive event. A missed Keep-Alive event causes the WD handler to
+fire.
+
+Data Path Interface
+===================
+I/O operations are based on Tx and Rx Submission Queues (Tx SQ and Rx
+SQ correspondingly). Each SQ has a completion queue (CQ) associated
+with it.
+
+The SQs and CQs are implemented as descriptor rings in contiguous
+physical memory.
+
+The ENA driver supports two Queue Operation modes for Tx SQs:
+
+- Regular mode
+
+  * In this mode the Tx SQs reside in the host's memory. The ENA
+    device fetches the ENA Tx descriptors and packet data from host
+    memory.
+
+- Low Latency Queue (LLQ) mode or "push-mode".
+
+  * In this mode the driver pushes the transmit descriptors and the
+    first 128 bytes of the packet directly to the ENA device memory
+    space. The rest of the packet payload is fetched by the
+    device. For this operation mode, the driver uses a dedicated PCI
+    device memory BAR, which is mapped with write-combine capability.
+
+The Rx SQs support only the regular mode.
+
+Note: Not all ENA devices support LLQ, and this feature is negotiated
+      with the device upon initialization. If the ENA device does not
+      support LLQ mode, the driver falls back to the regular mode.
+
+The driver supports multi-queue for both Tx and Rx. This has various
+benefits:
+
+- Reduced CPU/thread/process contention on a given Ethernet interface.
+- Cache miss rate on completion is reduced, particularly for data
+  cache lines that hold the sk_buff structures.
+- Increased process-level parallelism when handling received packets.
+- Increased data cache hit rate, by steering kernel processing of
+  packets to the CPU, where the application thread consuming the
+  packet is running.
+- In hardware interrupt re-direction.
+
+Interrupt Modes
+===============
+The driver assigns a single MSI-X vector per queue pair (for both Tx
+and Rx directions). The driver assigns an additional dedicated MSI-X vector
+for management (for ACQ and AENQ).
+
+Management interrupt registration is performed when the Linux kernel
+probes the adapter, and it is de-registered when the adapter is
+removed. I/O queue interrupt registration is performed when the Linux
+interface of the adapter is opened, and it is de-registered when the
+interface is closed.
+
+The management interrupt is named::
+
+   ena-mgmnt@pci:<PCI domain:bus:slot.function>
+
+and for each queue pair, an interrupt is named::
+
+   <interface name>-Tx-Rx-<queue index>
+
+The ENA device operates in auto-mask and auto-clear interrupt
+modes. That is, once MSI-X is delivered to the host, its Cause bit is
+automatically cleared and the interrupt is masked. The interrupt is
+unmasked by the driver after NAPI processing is complete.
+
+Interrupt Moderation
+====================
+ENA driver and device can operate in conventional or adaptive interrupt
+moderation mode.
+
+In conventional mode the driver instructs device to postpone interrupt
+posting according to static interrupt delay value. The interrupt delay
+value can be configured through ethtool(8). The following ethtool
+parameters are supported by the driver: tx-usecs, rx-usecs
+
+In adaptive interrupt moderation mode the interrupt delay value is
+updated by the driver dynamically and adjusted every NAPI cycle
+according to the traffic nature.
+
+By default ENA driver applies adaptive coalescing on Rx traffic and
+conventional coalescing on Tx traffic.
+
+Adaptive coalescing can be switched on/off through ethtool(8)
+adaptive_rx on|off parameter.
+
+The driver chooses interrupt delay value according to the number of
+bytes and packets received between interrupt unmasking and interrupt
+posting. The driver uses interrupt delay table that subdivides the
+range of received bytes/packets into 5 levels and assigns interrupt
+delay value to each level.
+
+The user can enable/disable adaptive moderation, modify the interrupt
+delay table and restore its default values through sysfs.
+
+RX copybreak
+============
+The rx_copybreak is initialized by default to ENA_DEFAULT_RX_COPYBREAK
+and can be configured by the ETHTOOL_STUNABLE command of the
+SIOCETHTOOL ioctl.
+
+SKB
+===
+The driver-allocated SKB for frames received from Rx handling using
+NAPI context. The allocation method depends on the size of the packet.
+If the frame length is larger than rx_copybreak, napi_get_frags()
+is used, otherwise netdev_alloc_skb_ip_align() is used, the buffer
+content is copied (by CPU) to the SKB, and the buffer is recycled.
+
+Statistics
+==========
+The user can obtain ENA device and driver statistics using ethtool.
+The driver can collect regular or extended statistics (including
+per-queue stats) from the device.
+
+In addition the driver logs the stats to syslog upon device reset.
+
+MTU
+===
+The driver supports an arbitrarily large MTU with a maximum that is
+negotiated with the device. The driver configures MTU using the
+SetFeature command (ENA_ADMIN_MTU property). The user can change MTU
+via ip(8) and similar legacy tools.
+
+Stateless Offloads
+==================
+The ENA driver supports:
+
+- TSO over IPv4/IPv6
+- TSO with ECN
+- IPv4 header checksum offload
+- TCP/UDP over IPv4/IPv6 checksum offloads
+
+RSS
+===
+- The ENA device supports RSS that allows flexible Rx traffic
+  steering.
+- Toeplitz and CRC32 hash functions are supported.
+- Different combinations of L2/L3/L4 fields can be configured as
+  inputs for hash functions.
+- The driver configures RSS settings using the AQ SetFeature command
+  (ENA_ADMIN_RSS_HASH_FUNCTION, ENA_ADMIN_RSS_HASH_INPUT and
+  ENA_ADMIN_RSS_REDIRECTION_TABLE_CONFIG properties).
+- If the NETIF_F_RXHASH flag is set, the 32-bit result of the hash
+  function delivered in the Rx CQ descriptor is set in the received
+  SKB.
+- The user can provide a hash key, hash function, and configure the
+  indirection table through ethtool(8).
+
+DATA PATH
+=========
+Tx
+--
+
+end_start_xmit() is called by the stack. This function does the following:
+
+- Maps data buffers (skb->data and frags).
+- Populates ena_buf for the push buffer (if the driver and device are
+  in push mode.)
+- Prepares ENA bufs for the remaining frags.
+- Allocates a new request ID from the empty req_id ring. The request
+  ID is the index of the packet in the Tx info. This is used for
+  out-of-order TX completions.
+- Adds the packet to the proper place in the Tx ring.
+- Calls ena_com_prepare_tx(), an ENA communication layer that converts
+  the ena_bufs to ENA descriptors (and adds meta ENA descriptors as
+  needed.)
+
+  * This function also copies the ENA descriptors and the push buffer
+    to the Device memory space (if in push mode.)
+
+- Writes doorbell to the ENA device.
+- When the ENA device finishes sending the packet, a completion
+  interrupt is raised.
+- The interrupt handler schedules NAPI.
+- The ena_clean_tx_irq() function is called. This function handles the
+  completion descriptors generated by the ENA, with a single
+  completion descriptor per completed packet.
+
+  * req_id is retrieved from the completion descriptor. The tx_info of
+    the packet is retrieved via the req_id. The data buffers are
+    unmapped and req_id is returned to the empty req_id ring.
+  * The function stops when the completion descriptors are completed or
+    the budget is reached.
+
+Rx
+--
+
+- When a packet is received from the ENA device.
+- The interrupt handler schedules NAPI.
+- The ena_clean_rx_irq() function is called. This function calls
+  ena_rx_pkt(), an ENA communication layer function, which returns the
+  number of descriptors used for a new unhandled packet, and zero if
+  no new packet is found.
+- Then it calls the ena_clean_rx_irq() function.
+- ena_eth_rx_skb() checks packet length:
+
+  * If the packet is small (len < rx_copybreak), the driver allocates
+    a SKB for the new packet, and copies the packet payload into the
+    SKB data buffer.
+
+    - In this way the original data buffer is not passed to the stack
+      and is reused for future Rx packets.
+
+  * Otherwise the function unmaps the Rx buffer, then allocates the
+    new SKB structure and hooks the Rx buffer to the SKB frags.
+
+- The new SKB is updated with the necessary information (protocol,
+  checksum hw verify result, etc.), and then passed to the network
+  stack, using the NAPI interface function napi_gro_receive().

+
+Viewing Link Messages
+---------------------
+  Link messages will not be displayed to the console if the distribution is
+  restricting system messages. In order to see network driver link messages on
+  your console, set dmesg to eight by entering the following::
+
+       dmesg -n 8
+
+  .. note::
+
+     This setting is not saved across reboots.
+
+Jumbo Frames
+------------
+  The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
+  enabled by changing the MTU to a value larger than the default of 1500.
+  The maximum value for the MTU is 16000.  Use the `ip` command to
+  increase the MTU size.  For example::
+
+	ip link set mtu 16000 dev enp1s0
+
+ethtool
+-------
+  The driver utilizes the ethtool interface for driver configuration and
+  diagnostics, as well as displaying statistical information. The latest
+  ethtool version is required for this functionality.

+
+ If you want to disable the output of messages::
+
+    ethtool -s <ethX> msglvl 0
+
+RX flow rules (ntuple filters)
+------------------------------
+
+ There are separate rules supported, that applies in that order:
+
+ 1. 16 VLAN ID rules
+ 2. 16 L2 EtherType rules
+ 3. 8 L3/L4 5-Tuple rules
+
+
+ The driver utilizes the ethtool interface for configuring ntuple filters,
+ via ``ethtool -N <device> <filter>``.
+
+ To enable or disable the RX flow rules::
+
+    ethtool -K ethX ntuple <on|off>
+
+ When disabling ntuple filters, all the user programed filters are
+ flushed from the driver cache and hardware. All needed filters must
+ be re-added when ntuple is re-enabled.
+
+ Because of the fixed order of the rules, the location of filters is also fixed:
+
+ - Locations 0 - 15 for VLAN ID filters
+ - Locations 16 - 31 for L2 EtherType filters
+ - Locations 32 - 39 for L3/L4 5-tuple filters (locations 32, 36 for IPv6)
+
+ The L3/L4 5-tuple (protocol, source and destination IP address, source and
+ destination TCP/UDP/SCTP port) is compared against 8 filters. For IPv4, up to
+ 8 source and destination addresses can be matched. For IPv6, up to 2 pairs of
+ addresses can be supported. Source and destination ports are only compared for
+ TCP/UDP/SCTP packets.
+
+ To add a filter that directs packet to queue 5, use
+ ``<-N|-U|--config-nfc|--config-ntuple>`` switch::
+
+    ethtool -N <ethX> flow-type udp4 src-ip 10.0.0.1 dst-ip 10.0.0.2 src-port 2000 dst-port 2001 action 5 <loc 32>
+
+ - action is the queue number.
+ - loc is the rule number.
+
+ For ``flow-type ip4|udp4|tcp4|sctp4|ip6|udp6|tcp6|sctp6`` you must set the loc
+ number within 32 - 39.
+ For ``flow-type ip4|udp4|tcp4|sctp4|ip6|udp6|tcp6|sctp6`` you can set 8 rules
+ for traffic IPv4 or you can set 2 rules for traffic IPv6. Loc number traffic
+ IPv6 is 32 and 36.
+ At the moment you can not use IPv4 and IPv6 filters at the same time.
+
+ Example filter for IPv6 filter traffic::
+
+    sudo ethtool -N <ethX> flow-type tcp6 src-ip 2001:db8:0:f101::1 dst-ip 2001:db8:0:f101::2 action 1 loc 32
+    sudo ethtool -N <ethX> flow-type ip6 src-ip 2001:db8:0:f101::2 dst-ip 2001:db8:0:f101::5 action -1 loc 36
+
+ Example filter for IPv4 filter traffic::
+
+    sudo ethtool -N <ethX> flow-type udp4 src-ip 10.0.0.4 dst-ip 10.0.0.7 src-port 2000 dst-port 2001 loc 32
+    sudo ethtool -N <ethX> flow-type tcp4 src-ip 10.0.0.3 dst-ip 10.0.0.9 src-port 2000 dst-port 2001 loc 33
+    sudo ethtool -N <ethX> flow-type ip4 src-ip 10.0.0.6 dst-ip 10.0.0.4 loc 34
+
+ If you set action -1, then all traffic corresponding to the filter will be discarded.
+
+ The maximum value action is 31.
+
+
+ The VLAN filter (VLAN id) is compared against 16 filters.
+ VLAN id must be accompanied by mask 0xF000. That is to distinguish VLAN filter
+ from L2 Ethertype filter with UserPriority since both User Priority and VLAN ID
+ are passed in the same 'vlan' parameter.
+
+ To add a filter that directs packets from VLAN 2001 to queue 5::
+
+    ethtool -N <ethX> flow-type ip4 vlan 2001 m 0xF000 action 1 loc 0
+
+
+ L2 EtherType filters allows filter packet by EtherType field or both EtherType
+ and User Priority (PCP) field of 802.1Q.
+ UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That is to
+ distinguish VLAN filter from L2 Ethertype filter with UserPriority since both
+ User Priority and VLAN ID are passed in the same 'vlan' parameter.
+
+ To add a filter that directs IP4 packess of priority 3 to queue 3::
+
+    ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF action 3 loc 16
+
+ To see the list of filters currently present::
+
+    ethtool <-u|-n|--show-nfc|--show-ntuple> <ethX>
+
+ Rules may be deleted from the table itself. This is done using::
+
+    sudo ethtool <-N|-U|--config-nfc|--config-ntuple> <ethX> delete <loc>
+
+ - loc is the rule number to be deleted.
+
+ Rx filters is an interface to load the filter table that funnels all flow
+ into queue 0 unless an alternative queue is specified using "action". In that
+ case, any flow that matches the filter criteria will be directed to the
+ appropriate queue. RX filters is supported on all kernels 2.6.30 and later.
+
+RSS for UDP
+-----------
+
+ Currently, NIC does not support RSS for fragmented IP packets, which leads to
+ incorrect working of RSS for fragmented UDP traffic. To disable RSS for UDP the
+ RX Flow L3/L4 rule may be used.
+
+ Example::
+
+    ethtool -N eth0 flow-type udp4 action 0 loc 32
+
+UDP GSO hardware offload
+------------------------
+
+ UDP GSO allows to boost UDP tx rates by offloading UDP headers allocation
+ into hardware. A special userspace socket option is required for this,
+ could be validated with /kernel/tools/testing/selftests/net/::
+
+    udpgso_bench_tx -u -4 -D 10.0.1.1 -s 6300 -S 100
+
+ Will cause sending out of 100 byte sized UDP packets formed from single
+ 6300 bytes user buffer.
+
+ UDP GSO is configured by::
+
+    ethtool -K eth0 tx-udp-segmentation on
+
+Private flags (testing)
+-----------------------
+
+ Atlantic driver supports private flags for hardware custom features::
+
+	$ ethtool --show-priv-flags ethX
+
+	Private flags for ethX:
+	DMASystemLoopback  : off
+	PKTSystemLoopback  : off
+	DMANetworkLoopback : off
+	PHYInternalLoopback: off
+	PHYExternalLoopback: off
+
+ Example::
+
+	$ ethtool --set-priv-flags ethX DMASystemLoopback on
+
+ DMASystemLoopback:   DMA Host loopback.
+ PKTSystemLoopback:   Packet buffer host loopback.
+ DMANetworkLoopback:  Network side loopback on DMA block.
+ PHYInternalLoopback: Internal loopback on Phy.
+ PHYExternalLoopback: External loopback on Phy (with loopback ethernet cable).
+
+
+Command Line Parameters
+=======================
+The following command line parameters are available on atlantic driver:
+
+aq_itr -Interrupt throttling mode
+---------------------------------
+Accepted values: 0, 1, 0xFFFF
+
+Default value: 0xFFFF
+
+======   ==============================================================
+0        Disable interrupt throttling.
+1        Enable interrupt throttling and use specified tx and rx rates.
+0xFFFF   Auto throttling mode. Driver will choose the best RX and TX
+	 interrupt throtting settings based on link speed.
+======   ==============================================================
+
+aq_itr_tx - TX interrupt throttle rate
+--------------------------------------
+
+Accepted values: 0 - 0x1FF
+
+Default value: 0
+
+TX side throttling in microseconds. Adapter will setup maximum interrupt delay
+to this value. Minimum interrupt delay will be a half of this value
+
+aq_itr_rx - RX interrupt throttle rate
+--------------------------------------
+
+Accepted values: 0 - 0x1FF
+
+Default value: 0
+
+RX side throttling in microseconds. Adapter will setup maximum interrupt delay
+to this value. Minimum interrupt delay will be a half of this value
+
+.. note::
+
+   ITR settings could be changed in runtime by ethtool -c means (see below)
+
+Config file parameters
+======================
+
+For some fine tuning and performance optimizations,
+some parameters can be changed in the {source_dir}/aq_cfg.h file.
+
+AQ_CFG_RX_PAGEORDER
+-------------------
+
+Default value: 0
+
+RX page order override. Thats a power of 2 number of RX pages allocated for
+each descriptor. Received descriptor size is still limited by
+AQ_CFG_RX_FRAME_MAX.
+
+Increasing pageorder makes page reuse better (actual on iommu enabled systems).
+
+AQ_CFG_RX_REFILL_THRES
+----------------------
+
+Default value: 32
+
+RX refill threshold. RX path will not refill freed descriptors until the
+specified number of free descriptors is observed. Larger values may help
+better page reuse but may lead to packet drops as well.
+
+AQ_CFG_VECS_DEF
+---------------
+
+Number of queues
+
+Valid Range: 0 - 8 (up to AQ_CFG_VECS_MAX)
+
+Default value: 8
+
+Notice this value will be capped by the number of cores available on the system.
+
+AQ_CFG_IS_RSS_DEF
+-----------------
+
+Enable/disable Receive Side Scaling
+
+This feature allows the adapter to distribute receive processing
+across multiple CPU-cores and to prevent from overloading a single CPU core.
+
+Valid values
+
+==  ========
+0   disabled
+1   enabled
+==  ========
+
+Default value: 1
+
+AQ_CFG_NUM_RSS_QUEUES_DEF
+-------------------------
+
+Number of queues for Receive Side Scaling
+
+Valid Range: 0 - 8 (up to AQ_CFG_VECS_DEF)
+
+Default value: AQ_CFG_VECS_DEF
+
+AQ_CFG_IS_LRO_DEF
+-----------------
+
+Enable/disable Large Receive Offload
+
+This offload enables the adapter to coalesce multiple TCP segments and indicate
+them as a single coalesced unit to the OS networking subsystem.
+
+The system consumes less energy but it also introduces more latency in packets
+processing.
+
+Valid values
+
+==  ========
+0   disabled
+1   enabled
+==  ========
+
+Default value: 1
+
+AQ_CFG_TX_CLEAN_BUDGET
+----------------------
+
+Maximum descriptors to cleanup on TX at once.
+
+Default value: 256
+
+After the aq_cfg.h file changed the driver must be rebuilt to take effect.
+

+
+Introduction
+============
+
+ This document describes the Linux driver for Chelsio 10Gb Ethernet Network
+ Controller. This driver supports the Chelsio N210 NIC and is backward
+ compatible with the Chelsio N110 model 10Gb NICs.
+
+
+Features
+========
+
+Adaptive Interrupts (adaptive-rx)
+---------------------------------
+
+  This feature provides an adaptive algorithm that adjusts the interrupt
+  coalescing parameters, allowing the driver to dynamically adapt the latency
+  settings to achieve the highest performance during various types of network

+
+TCP Segmentation Offloading (TSO) Support
+-----------------------------------------
+
+  This feature, also known as "large send", enables a system's protocol stack
+  to offload portions of outbound TCP processing to a network interface card
+  thereby reducing system CPU utilization and enhancing performance.
+
+  The interface used to control this feature is ethtool version 1.8 or higher.
+  Please see the ethtool manpage for additional usage information.
+
+  By default, TSO is enabled.
+  To disable TSO::
+
+      ethtool -K <interface> tso off
+
+  To enable TSO::
+
+      ethtool -K <interface> tso on
+
+  To view the status of TSO::
+
+      ethtool -k <interface>

+
+Performance
+===========
+
+ The following information is provided as an example of how to change system
+ parameters for "performance tuning" an what value to use. You may or may not
+ want to change these system parameters, depending on your server/workstation
+ application. Doing so is not warranted in any way by Chelsio Communications,
+ and is done at "YOUR OWN RISK". Chelsio will not be held responsible for loss
+ of data or damage to equipment.
+
+ Your distribution may have a different way of doing things, or you may prefer
+ a different method. These commands are shown only to provide an example of
+ what to do and are by no means definitive.
+
+ Making any of the following system changes will only last until you reboot
+ your system. You may want to write a script that runs at boot-up which
+ includes the optimal settings for your system.
+
+  Setting PCI Latency Timer::
+
+      setpci -d 1425::
+
+* 0x0c.l=0x0000F800
+
+  Disabling TCP timestamp::
+
+      sysctl -w net.ipv4.tcp_timestamps=0
+
+  Disabling SACK::
+
+      sysctl -w net.ipv4.tcp_sack=0
+
+  Setting large number of incoming connection requests::
+
+      sysctl -w net.ipv4.tcp_max_syn_backlog=3000
+
+  Setting maximum receive socket buffer size::
+
+      sysctl -w net.core.rmem_max=1024000
+
+  Setting maximum send socket buffer size::
+
+      sysctl -w net.core.wmem_max=1024000
+
+  Set smp_affinity (on a multiprocessor system) to a single CPU::
+
+      echo 1 > /proc/irq/<interrupt_number>/smp_affinity
+
+  Setting default receive socket buffer size::
+
+      sysctl -w net.core.rmem_default=524287
+
+  Setting default send socket buffer size::
+
+      sysctl -w net.core.wmem_default=524287
+
+  Setting maximum option memory buffers::
+
+      sysctl -w net.core.optmem_max=524287
+
+  Setting maximum backlog (# of unprocessed packets before kernel drops)::
+
+      sysctl -w net.core.netdev_max_backlog=300000
+
+  Setting TCP read buffers (min/default/max)::
+
+      sysctl -w net.ipv4.tcp_rmem="10000000 10000000 10000000"
+
+  Setting TCP write buffers (min/pressure/max)::
+
+      sysctl -w net.ipv4.tcp_wmem="10000000 10000000 10000000"
+
+  Setting TCP buffer space (min/pressure/max)::
+
+      sysctl -w net.ipv4.tcp_mem="10000000 10000000 10000000"
+
+  TCP window size for single connections:
+
+   The receive buffer (RX_WINDOW) size must be at least as large as the
+   Bandwidth-Delay Product of the communication link between the sender and
+   receiver. Due to the variations of RTT, you may want to increase the buffer
+   size up to 2 times the Bandwidth-Delay Product. Reference page 289 of
+   "TCP/IP Illustrated, Volume 1, The Protocols" by W. Richard Stevens.
+
+   At 10Gb speeds, use the following formula::
+
+       RX_WINDOW >= 1.25MBytes * RTT(in milliseconds)
+       Example for RTT with 100us: RX_WINDOW = (1,250,000 * 0.1) = 125,000
+
+   RX_WINDOW sizes of 256KB - 512KB should be sufficient.
+
+   Setting the min, max, and default receive buffer (RX_WINDOW) size::
+
+       sysctl -w net.ipv4.tcp_rmem="<min> <default> <max>"
+
+  TCP window size for multiple connections:
+   The receive buffer (RX_WINDOW) size may be calculated the same as single
+   connections, but should be divided by the number of connections. The
+   smaller window prevents congestion and facilitates better pacing,
+   especially if/when MAC level flow control does not work well or when it is
+   not supported on the machine. Experimentation may be necessary to attain
+   the correct value. This method is provided as a starting point for the
+   correct receive buffer size.
+
+   Setting the min, max, and default receive buffer (RX_WINDOW) size is
+   performed in the same manner as single connection.
+

+
+
+Known Issues
+============
+
+ These issues have been identified during testing. The following information
+ is provided as a workaround to the problem. In some cases, this problem is
+ inherent to Linux or to a particular Linux Distribution and/or hardware
+ platform.
+
+  1. Large number of TCP retransmits on a multiprocessor (SMP) system.
+
+      On a system with multiple CPUs, the interrupt (IRQ) for the network
+      controller may be bound to more than one CPU. This will cause TCP
+      retransmits if the packet data were to be split across different CPUs
+      and re-assembled in a different order than expected.
+
+      To eliminate the TCP retransmits, set smp_affinity on the particular
+      interrupt to a single CPU. You can locate the interrupt (IRQ) used on
+      the N110/N210 by using ifconfig::
+
+	  ifconfig <dev_name> | grep Interrupt
+
+      Set the smp_affinity to a single CPU::
+
+	  echo 1 > /proc/irq/<interrupt_number>/smp_affinity
+
+      It is highly suggested that you do not run the irqbalance daemon on your
+      system, as this will change any smp_affinity setting you have applied.
+      The irqbalance daemon runs on a 10 second interval and binds interrupts
+      to the least loaded CPU determined by the daemon. To disable this daemon::
+
+	  chkconfig --level 2345 irqbalance off
+
+      By default, some Linux distributions enable the kernel feature,
+      irqbalance, which performs the same function as the daemon. To disable
+      this feature, add the following line to your bootloader::
+
+	  noirqbalance
+
+	  Example using the Grub bootloader::
+
+	      title Red Hat Enterprise Linux AS (2.4.21-27.ELsmp)
+	      root (hd0,0)
+	      kernel /vmlinuz-2.4.21-27.ELsmp ro root=/dev/hda3 noirqbalance
+	      initrd /initrd-2.4.21-27.ELsmp.img
+
+  2. After running insmod, the driver is loaded and the incorrect network
+     interface is brought up without running ifup.
+
+      When using 2.4.x kernels, including RHEL kernels, the Linux kernel
+      invokes a script named "hotplug". This script is primarily used to
+      automatically bring up USB devices when they are plugged in, however,
+      the script also attempts to automatically bring up a network interface
+      after loading the kernel module. The hotplug script does this by scanning
+      the ifcfg-eth# config files in /etc/sysconfig/network-scripts, looking
+      for HWADDR=<mac_address>.
+
+      If the hotplug script does not find the HWADDRR within any of the
+      ifcfg-eth# files, it will bring up the device with the next available
+      interface name. If this interface is already configured for a different
+      network card, your new interface will have incorrect IP address and
+      network settings.
+
+      To solve this issue, you can add the HWADDR=<mac_address> key to the
+      interface config file of your network controller.
+
+      To disable this "hotplug" feature, you may add the driver (module name)
+      to the "blacklist" file located in /etc/hotplug. It has been noted that
+      this does not work for network devices because the net.agent script
+      does not use the blacklist file. Simply remove, or rename, the net.agent
+      script located in /etc/hotplug to disable this feature.
+
+  3. Transport Protocol (TP) hangs when running heavy multi-connection traffic
+     on an AMD Opteron system with HyperTransport PCI-X Tunnel chipset.
+
+      If your AMD Opteron system uses the AMD-8131 HyperTransport PCI-X Tunnel
+      chipset, you may experience the "133-Mhz Mode Split Completion Data
+      Corruption" bug identified by AMD while using a 133Mhz PCI-X card on the
+      bus PCI-X bus.
+
+      AMD states, "Under highly specific conditions, the AMD-8131 PCI-X Tunnel
+      can provide stale data via split completion cycles to a PCI-X card that
+      is operating at 133 Mhz", causing data corruption.
+
+      AMD's provides three workarounds for this problem, however, Chelsio
+      recommends the first option for best performance with this bug:
+
+	For 133Mhz secondary bus operation, limit the transaction length and
+	the number of outstanding transactions, via BIOS configuration
+	programming of the PCI-X card, to the following:
+
+	   Data Length (bytes): 1k
+
+	   Total allowed outstanding transactions: 2
+
+      Please refer to AMD 8131-HT/PCI-X Errata 26310 Rev 3.08 August 2004,
+      section 56, "133-MHz Mode Split Completion Data Corruption" for more
+      details with this bug and workarounds suggested by AMD.
+
+      It may be possible to work outside AMD's recommended PCI-X settings, try
+      increasing the Data Length to 2k bytes for increased performance. If you
+      have issues with these settings, please revert to the "safe" settings
+      and duplicate the problem before submitting a bug or asking for support.
+
+      .. note::
+
+	    The default setting on most systems is 8 outstanding transactions
+	    and 2k bytes data length.
+
+  4. On multiprocessor systems, it has been noted that an application which
+     is handling 10Gb networking can switch between CPUs causing degraded
+     and/or unstable performance.
+
+      If running on an SMP system and taking performance measurements, it
+      is suggested you either run the latest netperf-2.4.0+ or use a binding
+      tool such as Tim Hockin's procstate utilities (runon)
+      <http://www.hockin.org/~thockin/procstate/>.
+
+      Binding netserver and netperf (or other applications) to particular
+      CPUs will have a significant difference in performance measurements.
+      You may need to experiment which CPU to bind the application to in
+      order to achieve the best performance for your system.
+
+      If you are developing an application designed for 10Gb networking,
+      please keep in mind you may want to look at kernel functions
+      sched_setaffinity & sched_getaffinity to bind your application.
+
+      If you are just running user-space applications such as ftp, telnet,
+      etc., you may want to try the runon tool provided by Tim Hockin's
+      procstate utility. You could also try binding the interface to a
+      particular CPU: runon 0 ifup eth0

+1. Cirrus Logic LAN CS8900/CS8920 Ethernet Adapters
+===================================================
+
+
+1.1. Product Overview
+=====================
+
+The CS8900-based ISA Ethernet Adapters from Cirrus Logic follow
+IEEE 802.3 standards and support half or full-duplex operation in ISA bus
+computers on 10 Mbps Ethernet networks.  The adapters are designed for operation
+in 16-bit ISA or EISA bus expansion slots and are available in
+10BaseT-only or 3-media configurations (10BaseT, 10Base2, and AUI for 10Base-5
+or fiber networks).
+
+CS8920-based adapters are similar to the CS8900-based adapter with additional
+features for Plug and Play (PnP) support and Wakeup Frame recognition.  As
+such, the configuration procedures differ somewhat between the two types of
+adapters.  Refer to the "Adapter Configuration" section for details on
+configuring both types of adapters.
+
+
+1.2. Driver Description
+=======================
+
+The CS8900/CS8920 Ethernet Adapter driver for Linux supports the Linux
+v2.3.48 or greater kernel.  It can be compiled directly into the kernel
+or loaded at run-time as a device driver module.
+
+1.2.1 Driver Name: cs89x0

+
+
+
+2. Adapter Installation and Configuration
+=========================================
+
+Both the CS8900 and CS8920-based adapters can be configured using parameters
+stored in an on-board EEPROM. You must use the DOS-based CS8900/20 Setup
+Utility if you want to change the adapter's configuration in EEPROM.
+
+When loading the driver as a module, you can specify many of the adapter's
+configuration parameters on the command-line to override the EEPROM's settings
+or for interface configuration when an EEPROM is not used. (CS8920-based
+adapters must use an EEPROM.) See Section 3.0 LOADING THE DRIVER AS A MODULE.
+
+Since the CS8900/20 Setup Utility is a DOS-based application, you must install
+and configure the adapter in a DOS-based system using the CS8900/20 Setup
+Utility before installation in the target LINUX system.  (Not required if
+installing a CS8900-based adapter and the default configuration is acceptable.)
+
+
+2.1. CS8900-based Adapter Configuration
+---------------------------------------
+
+CS8900-based adapters shipped from Cirrus Logic have been configured
+with the following "default" settings::
+
+  Operation Mode:      Memory Mode
+  IRQ:                 10
+  Base I/O Address:    300
+  Memory Base Address: D0000
+  Optimization:	       DOS Client
+  Transmission Mode:   Half-duplex
+  BootProm:            None
+  Media Type:	       Autodetect (3-media cards) or
+		       10BASE-T (10BASE-T only adapter)
+
+You should only change the default configuration settings if conflicts with
+another adapter exists. To change the adapter's configuration, run the
+CS8900/20 Setup Utility.
+
+
+2.2. CS8920-based Adapter Configuration
+---------------------------------------
+
+CS8920-based adapters are shipped from Cirrus Logic configured as Plug
+and Play (PnP) enabled.  However, since the cs89x0 driver does NOT
+support PnP, you must install the CS8920 adapter in a DOS-based PC and
+run the CS8900/20 Setup Utility to disable PnP and configure the
+adapter before installation in the target Linux system.  Failure to do
+this will leave the adapter inactive and the driver will be unable to
+communicate with the adapter.

+
+
+3. Loading the Driver as a Module
+=================================
+
+If the driver is compiled as a loadable module, you can load the driver module
+with the 'modprobe' command.  Many of the adapter's configuration parameters can
+be specified as command-line arguments to the load command.  This facility
+provides a means to override the EEPROM's settings or for interface
+configuration when an EEPROM is not used.
+
+Example::
+
+    insmod cs89x0.o io=0x200 irq=0xA media=aui
+
+This example loads the module and configures the adapter to use an IO port base
+address of 200h, interrupt 10, and use the AUI media connection.  The following
+configuration options are available on the command line::
+
+  io=###               - specify IO address (200h-360h)
+  irq=##               - specify interrupt level
+  use_dma=1            - Enable DMA
+  dma=#                - specify dma channel (Driver is compiled to support
+			 Rx DMA only)
+  dmasize=# (16 or 64) - DMA size 16K or 64K.  Default value is set to 16.
+  media=rj45           - specify media type
+   or media=bnc
+   or media=aui
+   or media=auto
+  duplex=full          - specify forced half/full/autonegotiate duplex
+   or duplex=half
+   or duplex=auto
+  debug=#              - debug level (only available if the driver was compiled
+			 for debugging)
+
+**Notes:**
+
+a) If an EEPROM is present, any specified command-line parameter
+   will override the corresponding configuration value stored in
+   EEPROM.
+
+b) The "io" parameter must be specified on the command-line.
+
+c) The driver's hardware probe routine is designed to avoid
+   writing to I/O space until it knows that there is a cs89x0
+   card at the written addresses.  This could cause problems
+   with device probing.  To avoid this behaviour, add one
+   to the ``io=`` module parameter.  This doesn't actually change
+   the I/O address, but it is a flag to tell the driver
+   to partially initialise the hardware before trying to
+   identify the card.  This could be dangerous if you are
+   not sure that there is a cs89x0 card at the provided address.
+
+   For example, to scan for an adapter located at IO base 0x300,
+   specify an IO address of 0x301.
+
+d) The "duplex=auto" parameter is only supported for the CS8920.
+
+e) The minimum command-line configuration required if an EEPROM is
+   not present is:
+
+   io
+   irq
+   media type (no autodetect)
+
+f) The following additional parameters are CS89XX defaults (values
+   used with no EEPROM or command-line argument).
+
+   * DMA Burst = enabled
+   * IOCHRDY Enabled = enabled
+   * UseSA = enabled
+   * CS8900 defaults to half-duplex if not specified on command-line
+   * CS8920 defaults to autoneg if not specified on command-line
+   * Use reset defaults for other config parameters
+   * dma_mode = 0
+
+g) You can use ifconfig to set the adapter's Ethernet address.
+
+h) Many Linux distributions use the 'modprobe' command to load
+   modules.  This program uses the '/etc/conf.modules' file to
+   determine configuration information which is passed to a driver
+   module when it is loaded.  All the configuration options which are
+   described above may be placed within /etc/conf.modules.
+
+   For example::
+
+     > cat /etc/conf.modules
+     ...
+     alias eth0 cs89x0
+     options cs89x0 io=0x0200 dma=5 use_dma=1
+     ...
+
+   In this example we are telling the module system that the
+   ethernet driver for this machine should use the cs89x0 driver.  We
+   are asking 'modprobe' to pass the 'io', 'dma' and 'use_dma'
+   arguments to the driver when it is loaded.
+
+i) Cirrus recommend that the cs89x0 use the ISA DMA channels 5, 6 or
+   7.  You will probably find that other DMA channels will not work.
+
+j) The cs89x0 supports DMA for receiving only.  DMA mode is
+   significantly more efficient.  Flooding a 400 MHz Celeron machine
+   with large ping packets consumes 82% of its CPU capacity in non-DMA
+   mode.  With DMA this is reduced to 45%.
+
+k) If your Linux kernel was compiled with inbuilt plug-and-play
+   support you will be able to find information about the cs89x0 card
+   with the command::
+
+     cat /proc/isapnp
+
+l) If during DMA operation you find erratic behavior or network data
+   corruption you should use your PC's BIOS to slow the EISA bus clock.
+
+m) If the cs89x0 driver is compiled directly into the kernel
+   (non-modular) then its I/O address is automatically determined by
+   ISA bus probing.  The IRQ number, media options, etc are determined
+   from the card's EEPROM.
+
+n) If the cs89x0 driver is compiled directly into the kernel, DMA
+   mode may be selected by providing the kernel with a boot option
+   'cs89x0_dma=N' where 'N' is the desired DMA channel number (5, 6 or 7).
+
+   Kernel boot options may be provided on the LILO command line::
+
+	LILO boot: linux cs89x0_dma=5
+
+   or they may be placed in /etc/lilo.conf::
+
+	image=/boot/bzImage-2.3.48
+	  append="cs89x0_dma=5"
+	  label=linux
+	  root=/dev/hda5
+	  read-only
+
+   The DMA Rx buffer size is hardwired to 16 kbytes in this mode.
+   (64k mode is not available).
+
+
+4. Compiling the Driver
+=======================
+
+The cs89x0 driver can be compiled directly into the kernel or compiled into
+a loadable device driver module.
+
+Just use the standard way to configure the driver and compile the Kernel.
+
+
+4.1. Compiling the Driver to Support Rx DMA
+-------------------------------------------
+
+The compile-time optionality for DMA was removed in the 2.3 kernel
+series.  DMA support is now unconditionally part of the driver.  It is
+enabled by the 'use_dma=1' module option.
+
+
+5. Testing and Troubleshooting
+==============================
+
+5.1. Known Defects and Limitations
+----------------------------------
+
+Refer to the RELEASE.TXT file distributed as part of this archive for a list of
+known defects, driver limitations, and work arounds.
+
+
+5.2. Testing the Adapter
+------------------------
+
+Once the adapter has been installed and configured, the diagnostic option of
+the CS8900/20 Setup Utility can be used to test the functionality of the
+adapter and its network connection.  Use the diagnostics 'Self Test' option to
+test the functionality of the adapter with the hardware configuration you have
+assigned. You can use the diagnostics 'Network Test' to test the ability of the
+adapter to communicate across the Ethernet with another PC equipped with a
+CS8900/20-based adapter card (it must also be running the CS8900/20 Setup
+Utility).
+
+.. note::
+
+	 The Setup Utility's diagnostics are designed to run in a
+	 DOS-only operating system environment.  DO NOT run the diagnostics
+	 from a DOS or command prompt session under Windows 95, Windows NT,
+	 OS/2, or other operating system.
+
+To run the diagnostics tests on the CS8900/20 adapter:
+
+   1.  Boot DOS on the PC and start the CS8900/20 Setup Utility.
+
+   2.  The adapter's current configuration is displayed.  Hit the ENTER key to
+       get to the main menu.
+
+   4.  Select 'Diagnostics' (ALT-G) from the main menu.
+       * Select 'Self-Test' to test the adapter's basic functionality.
+       * Select 'Network Test' to test the network connection and cabling.
+
+
+5.2.1. Diagnostic Self-test
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The diagnostic self-test checks the adapter's basic functionality as well as
+its ability to communicate across the ISA bus based on the system resources
+assigned during hardware configuration.  The following tests are performed:
+
+   * IO Register Read/Write Test
+
+     The IO Register Read/Write test insures that the CS8900/20 can be
+     accessed in IO mode, and that the IO base address is correct.
+
+   * Shared Memory Test
+
+     The Shared Memory test insures the CS8900/20 can be accessed in memory
+     mode and that the range of memory addresses assigned does not conflict
+     with other devices in the system.
+
+   * Interrupt Test
+
+     The Interrupt test insures there are no conflicts with the assigned IRQ
+     signal.
+
+   * EEPROM Test
+
+     The EEPROM test insures the EEPROM can be read.
+
+   * Chip RAM Test
+
+     The Chip RAM test insures the 4K of memory internal to the CS8900/20 is
+     working properly.
+
+   * Internal Loop-back Test
+
+     The Internal Loop Back test insures the adapter's transmitter and
+     receiver are operating properly.  If this test fails, make sure the
+     adapter's cable is connected to the network (check for LED activity for
+     example).
+
+   * Boot PROM Test
+
+     The Boot PROM  test insures the Boot PROM is present, and can be read.
+     Failure indicates the Boot PROM  was not successfully read due to a
+     hardware problem or due to a conflicts on the Boot PROM address
+     assignment. (Test only applies if the adapter is configured to use the
+     Boot PROM option.)
+
+Failure of a test item indicates a possible system resource conflict with
+another device on the ISA bus.  In this case, you should use the Manual Setup
+option to reconfigure the adapter by selecting a different value for the system
+resource that failed.
+
+
+5.2.2. Diagnostic Network Test
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The Diagnostic Network Test verifies a working network connection by
+transferring data between two CS8900/20 adapters installed in different PCs
+on the same network. (Note: the diagnostic network test should not be run
+between two nodes across a router.)
+
+This test requires that each of the two PCs have a CS8900/20-based adapter
+installed and have the CS8900/20 Setup Utility running.  The first PC is
+configured as a Responder and the other PC is configured as an Initiator.
+Once the Initiator is started, it sends data frames to the Responder which
+returns the frames to the Initiator.
+
+The total number of frames received and transmitted are displayed on the
+Initiator's display, along with a count of the number of frames received and
+transmitted OK or in error.  The test can be terminated anytime by the user at
+either PC.
+
+To setup the Diagnostic Network Test:
+
+    1.  Select a PC with a CS8900/20-based adapter and a known working network
+	connection to act as the Responder.  Run the CS8900/20 Setup Utility
+	and select 'Diagnostics -> Network Test -> Responder' from the main
+	menu.  Hit ENTER to start the Responder.
+
+    2.  Return to the PC with the CS8900/20-based adapter you want to test and
+	start the CS8900/20 Setup Utility.
+
+    3.  From the main menu, Select 'Diagnostic -> Network Test -> Initiator'.
+	Hit ENTER to start the test.
+
+You may stop the test on the Initiator at any time while allowing the Responder
+to continue running.  In this manner, you can move to additional PCs and test
+them by starting the Initiator on another PC without having to stop/start the
+Responder.
+
+
+
+5.3. Using the Adapter's LEDs
+-----------------------------
+
+The 2 and 3-media adapters have two LEDs visible on the back end of the board
+located near the 10Base-T connector.
+
+Link Integrity LED: A "steady" ON of the green LED indicates a valid 10Base-T
+connection.  (Only applies to 10Base-T.  The green LED has no significance for
+a 10Base-2 or AUI connection.)
+
+TX/RX LED: The yellow LED lights briefly each time the adapter transmits or
+receives data. (The yellow LED will appear to "flicker" on a typical network.)
+
+
+5.4. Resolving I/O Conflicts
+----------------------------
+
+An IO conflict occurs when two or more adapter use the same ISA resource (IO
+address, memory address or IRQ).  You can usually detect an IO conflict in one
+of four ways after installing and or configuring the CS8900/20-based adapter:
+
+    1.  The system does not boot properly (or at all).
+
+    2.  The driver cannot communicate with the adapter, reporting an "Adapter
+	not found" error message.
+
+    3.  You cannot connect to the network or the driver will not load.
+
+    4.  If you have configured the adapter to run in memory mode but the driver
+	reports it is using IO mode when loading, this is an indication of a
+	memory address conflict.
+
+If an IO conflict occurs, run the CS8900/20 Setup Utility and perform a
+diagnostic self-test.  Normally, the ISA resource in conflict will fail the
+self-test.  If so, reconfigure the adapter selecting another choice for the
+resource in conflict.  Run the diagnostics again to check for further IO
+conflicts.
+
+In some cases, such as when the PC will not boot, it may be necessary to remove
+the adapter and reconfigure it by installing it in another PC to run the
+CS8900/20 Setup Utility.  Once reinstalled in the target system, run the
+diagnostics self-test to ensure the new configuration is free of conflicts
+before loading the driver again.
+
+When manually configuring the adapter, keep in mind the typical ISA system
+resource usage as indicated in the tables below.
+
+::
+
+  I/O Address    	Device                        IRQ      Device
+  -----------    	--------                      ---      --------

+DM9000 Network driver
+=====================
+
+Copyright 2008 Simtec Electronics,
+
+	  Ben Dooks <ben@simtec.co.uk> <ben-linux@fluff.org>
+
+
+Introduction
+------------
+
+This file describes how to use the DM9000 platform-device based network driver
+that is contained in the files drivers/net/dm9000.c and drivers/net/dm9000.h.
+
+The driver supports three DM9000 variants, the DM9000E which is the first chip
+supported as well as the newer DM9000A and DM9000B devices. It is currently
+maintained and tested by Ben Dooks, who should be CC: to any patches for this
+driver.
+
+
+Defining the platform device
+----------------------------
+
+The minimum set of resources attached to the platform device are as follows:
+
+    1) The physical address of the address register
+    2) The physical address of the data register
+    3) The IRQ line the device's interrupt pin is connected to.
+
+These resources should be specified in that order, as the ordering of the
+two address regions is important (the driver expects these to be address
+and then data).
+
+An example from arch/arm/mach-s3c2410/mach-bast.c is::
+
+  static struct resource bast_dm9k_resource[] = {
+	[0] = {
+		.start = S3C2410_CS5 + BAST_PA_DM9000,
+		.end   = S3C2410_CS5 + BAST_PA_DM9000 + 3,
+		.flags = IORESOURCE_MEM,
+	},
+	[1] = {
+		.start = S3C2410_CS5 + BAST_PA_DM9000 + 0x40,
+		.end   = S3C2410_CS5 + BAST_PA_DM9000 + 0x40 + 0x3f,
+		.flags = IORESOURCE_MEM,
+	},
+	[2] = {
+		.start = IRQ_DM9000,
+		.end   = IRQ_DM9000,
+		.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,
+	}
+  };
+
+  static struct platform_device bast_device_dm9k = {
+	.name		= "dm9000",
+	.id		= 0,
+	.num_resources	= ARRAY_SIZE(bast_dm9k_resource),
+	.resource	= bast_dm9k_resource,
+  };
+
+Note the setting of the IRQ trigger flag in bast_dm9k_resource[2].flags,
+as this will generate a warning if it is not present. The trigger from
+the flags field will be passed to request_irq() when registering the IRQ
+handler to ensure that the IRQ is setup correctly.
+
+This shows a typical platform device, without the optional configuration
+platform data supplied. The next example uses the same resources, but adds
+the optional platform data to pass extra configuration data::
+
+  static struct dm9000_plat_data bast_dm9k_platdata = {
+	.flags		= DM9000_PLATF_16BITONLY,
+  };
+
+  static struct platform_device bast_device_dm9k = {
+	.name		= "dm9000",
+	.id		= 0,
+	.num_resources	= ARRAY_SIZE(bast_dm9k_resource),
+	.resource	= bast_dm9k_resource,
+	.dev		= {
+		.platform_data = &bast_dm9k_platdata,
+	}
+  };
+
+The platform data is defined in include/linux/dm9000.h and described below.
+
+
+Platform data
+-------------
+
+Extra platform data for the DM9000 can describe the IO bus width to the
+device, whether or not an external PHY is attached to the device and
+the availability of an external configuration EEPROM.
+
+The flags for the platform data .flags field are as follows:
+
+DM9000_PLATF_8BITONLY
+
+	The IO should be done with 8bit operations.
+
+DM9000_PLATF_16BITONLY
+
+	The IO should be done with 16bit operations.
+
+DM9000_PLATF_32BITONLY
+
+	The IO should be done with 32bit operations.
+
+DM9000_PLATF_EXT_PHY
+
+	The chip is connected to an external PHY.
+
+DM9000_PLATF_NO_EEPROM
+
+	This can be used to signify that the board does not have an
+	EEPROM, or that the EEPROM should be hidden from the user.
+
+DM9000_PLATF_SIMPLE_PHY
+
+	Switch to using the simpler PHY polling method which does not
+	try and read the MII PHY state regularly. This is only available
+	when using the internal PHY. See the section on link state polling
+	for more information.
+
+	The config symbol DM9000_FORCE_SIMPLE_PHY_POLL, Kconfig entry
+	"Force simple NSR based PHY polling" allows this flag to be
+	forced on at build time.
+
+
+PHY Link state polling
+----------------------
+
+The driver keeps track of the link state and informs the network core
+about link (carrier) availability. This is managed by several methods
+depending on the version of the chip and on which PHY is being used.
+
+For the internal PHY, the original (and currently default) method is
+to read the MII state, either when the status changes if we have the
+necessary interrupt support in the chip or every two seconds via a
+periodic timer.
+
+To reduce the overhead for the internal PHY, there is now the option
+of using the DM9000_FORCE_SIMPLE_PHY_POLL config, or DM9000_PLATF_SIMPLE_PHY
+platform data option to read the summary information without the
+expensive MII accesses. This method is faster, but does not print
+as much information.
+
+When using an external PHY, the driver currently has to poll the MII
+link status as there is no method for getting an interrupt on link change.
+
+
+DM9000A / DM9000B
+-----------------
+
+These chips are functionally similar to the DM9000E and are supported easily
+by the same driver. The features are:
+
+   1) Interrupt on internal PHY state change. This means that the periodic
+      polling of the PHY status may be disabled on these devices when using
+      the internal PHY.
+
+   2) TCP/UDP checksum offloading, which the driver does not currently support.
+
+
+ethtool
+-------
+
+The driver supports the ethtool interface for access to the driver
+state information, the PHY state and the EEPROM.

+===================================
+DEC EtherWORKS Ethernet De4x5 cards
+===================================
+
+    Originally,   this  driver  was    written  for the  Digital   Equipment
+    Corporation series of EtherWORKS Ethernet cards:
+
+	 - DE425 TP/COAX EISA
+	 - DE434 TP PCI
+	 - DE435 TP/COAX/AUI PCI
+	 - DE450 TP/COAX/AUI PCI
+	 - DE500 10/100 PCI Fasternet
+
+    but it  will  now attempt  to  support all  cards which   conform to the
+    Digital Semiconductor   SROM   Specification.    The  driver   currently
+    recognises the following chips:
+
+	 - DC21040  (no SROM)
+	 - DC21041[A]
+	 - DC21140[A]
+	 - DC21142
+	 - DC21143
+
+    So far the driver is known to work with the following cards:
+
+	 - KINGSTON
+	 - Linksys
+	 - ZNYX342
+	 - SMC8432
+	 - SMC9332 (w/new SROM)
+	 - ZNYX31[45]
+	 - ZNYX346 10/100 4 port (can act as a 10/100 bridge!)
+
+    The driver has been tested on a relatively busy network using the DE425,
+    DE434, DE435 and DE500 cards and benchmarked with 'ttcp': it transferred
+    16M of data to a DECstation 5000/200 as follows::
+
+		  TCP           UDP
+	       TX     RX     TX     RX
+      DE425   1030k  997k   1170k  1128k
+      DE434   1063k  995k   1170k  1125k
+      DE435   1063k  995k   1170k  1125k
+      DE500   1063k  998k   1170k  1125k  in 10Mb/s mode
+
+    All  values are typical (in   kBytes/sec) from a  sample  of 4 for  each
+    measurement. Their error is +/-20k on a quiet (private) network and also
+    depend on what load the CPU has.
+
+----------------------------------------------------------------------------
+
+    The ability to load this  driver as a loadable  module has been included
+    and used extensively  during the driver development  (to save those long
+    reboot sequences).  Loadable module support  under PCI and EISA has been
+    achieved by letting the driver autoprobe as if it were compiled into the
+    kernel. Do make sure  you're not sharing  interrupts with anything  that
+    cannot accommodate  interrupt  sharing!
+
+    To utilise this ability, you have to do 8 things:
+
+    0) have a copy of the loadable modules code installed on your system.
+    1) copy de4x5.c from the  /linux/drivers/net directory to your favourite
+       temporary directory.
+    2) for fixed  autoprobes (not  recommended),  edit the source code  near
+       line 5594 to reflect the I/O address  you're using, or assign these when
+       loading by::
+
+		   insmod de4x5 io=0xghh           where g = bus number
+							hh = device number
+
+       .. note::
+
+	   autoprobing for modules is now supported by default. You may just
+	   use::
+
+		   insmod de4x5
+
+	   to load all available boards. For a specific board, still use
+	   the 'io=?' above.
+    3) compile  de4x5.c, but include -DMODULE in  the command line to ensure
+       that the correct bits are compiled (see end of source code).
+    4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
+       kernel with the de4x5 configuration turned off and reboot.
+    5) insmod de4x5 [io=0xghh]
+    6) run the net startup bits for your new eth?? interface(s) manually
+       (usually /etc/rc.inet[12] at boot time).
+    7) enjoy!
+
+    To unload a module, turn off the associated interface(s)
+    'ifconfig eth?? down' then 'rmmod de4x5'.
+
+    Automedia detection is included so that in  principle you can disconnect
+    from, e.g.  TP, reconnect  to BNC  and  things will still work  (after a
+    pause while the   driver figures out   where its media went).  My tests
+    using ping showed that it appears to work....
+
+    By  default,  the driver will  now   autodetect any  DECchip based card.
+    Should you have a need to restrict the driver to DIGITAL only cards, you
+    can compile with a  DEC_ONLY define, or if  loading as a module, use the
+    'dec_only=1'  parameter.
+
+    I've changed the timing routines to  use the kernel timer and scheduling
+    functions  so that the  hangs  and other assorted problems that occurred
+    while autosensing the  media  should be gone.  A  bonus  for the DC21040
+    auto  media sense algorithm is  that it can now  use one that is more in
+    line with the  rest (the DC21040  chip doesn't  have a hardware  timer).
+    The downside is the 1 'jiffies' (10ms) resolution.
+
+    IEEE 802.3u MII interface code has  been added in anticipation that some
+    products may use it in the future.
+
+    The SMC9332 card  has a non-compliant SROM  which needs fixing -  I have
+    patched this  driver to detect it  because the SROM format used complies
+    to a previous DEC-STD format.
+
+    I have removed the buffer copies needed for receive on Intels.  I cannot
+    remove them for   Alphas since  the  Tulip hardware   only does longword
+    aligned  DMA transfers  and  the  Alphas get   alignment traps with  non
+    longword aligned data copies (which makes them really slow). No comment.
+
+    I  have added SROM decoding  routines to make this  driver work with any
+    card that  supports the Digital  Semiconductor SROM spec. This will help
+    all  cards running the dc2114x  series chips in particular.  Cards using
+    the dc2104x  chips should run correctly with  the basic  driver.  I'm in
+    debt to <mjacob@feral.com> for the  testing and feedback that helped get
+    this feature working.  So far we have  tested KINGSTON, SMC8432, SMC9332
+    (with the latest SROM complying  with the SROM spec  V3: their first was
+    broken), ZNYX342  and  LinkSys. ZNYX314 (dual  21041  MAC) and  ZNYX 315
+    (quad 21041 MAC)  cards also  appear  to work despite their  incorrectly
+    wired IRQs.
+
+    I have added a temporary fix for interrupt problems when some SCSI cards
+    share the same interrupt as the DECchip based  cards. The problem occurs
+    because  the SCSI card wants to  grab the interrupt  as a fast interrupt
+    (runs the   service routine with interrupts turned   off) vs.  this card
+    which really needs to run the service routine with interrupts turned on.
+    This driver will  now   add the interrupt service   routine  as  a  fast
+    interrupt if it   is bounced from the   slow interrupt.  THIS IS NOT   A
+    RECOMMENDED WAY TO RUN THE DRIVER  and has been done  for a limited time
+    until  people   sort  out their  compatibility    issues and the  kernel
+    interrupt  service code  is  fixed.   YOU  SHOULD SEPARATE OUT  THE FAST
+    INTERRUPT CARDS FROM THE SLOW INTERRUPT CARDS to ensure that they do not
+    run on the same interrupt. PCMCIA/CardBus is another can of worms...
+
+    Finally, I think  I have really  fixed  the module  loading problem with
+    more than one DECchip based  card.  As a  side effect, I don't mess with
+    the  device structure any  more which means that  if more than 1 card in
+    2.0.x is    installed (4  in   2.1.x),  the  user   will have   to  edit
+    linux/drivers/net/Space.c  to make room for  them. Hence, module loading
+    is  the preferred way to use   this driver, since  it  doesn't have this
+    limitation.
+
+    Where SROM media  detection is used and  full duplex is specified in the
+    SROM,  the feature is  ignored unless  lp->params.fdx  is set at compile
+    time  OR during  a   module load  (insmod  de4x5   args='eth??:fdx' [see
+    below]).  This is because there  is no way  to automatically detect full
+    duplex   links  except through   autonegotiation.    When I  include the
+    autonegotiation feature in  the SROM autoconf  code, this detection will
+    occur automatically for that case.
+
+    Command line  arguments are  now allowed, similar to  passing  arguments
+    through LILO. This will allow a per adapter board set  up of full duplex
+    and media. The only lexical constraints are:  the board name (dev->name)
+    appears in  the list before its parameters.  The list of parameters ends
+    either at the end of the parameter list or with another board name.  The
+    following parameters are allowed:
+
+	    =========  ===============================================
+	    fdx        for full duplex
+	    autosense  to set the media/speed; with the following
+		       sub-parameters:
+		       TP, TP_NW, BNC, AUI, BNC_AUI, 100Mb, 10Mb, AUTO
+	    =========  ===============================================
+
+    Case sensitivity is important  for  the sub-parameters. They *must*   be
+    upper case. Examples::
+
+	insmod de4x5 args='eth1:fdx autosense=BNC eth0:autosense=100Mb'.
+
+    For a compiled in driver, in linux/drivers/net/CONFIG, place e.g.::
+
+	DE4X5_OPTS = -DDE4X5_PARM='"eth0:fdx autosense=AUI eth2:autosense=TP"'
+
+    Yes,  I know full duplex  isn't permissible on BNC  or AUI; they're just
+    examples. By default, full duplex is turned  off and AUTO is the default
+    autosense setting. In  reality, I expect only the  full duplex option to
+    be used. Note the use of single quotes in the two examples above and the
+    lack of commas to separate items.

+
+This driver provides kernel support for Davicom DM9102(A)/DM9132/DM9801 ethernet cards ( CNET
+10/100 ethernet cards uses Davicom chipset too, so this driver supports CNET cards too ).If you
+didn't compile this driver as a module, it will automatically load itself on boot and print a
+line similar to::
+
+	dmfe: Davicom DM9xxx net driver, version 1.36.4 (2002-01-17)
+
+If you compiled this driver as a module, you have to load it on boot.You can load it with command::
+
+	insmod dmfe
+
+This way it will autodetect the device mode.This is the suggested way to load the module.Or you can pass
+a mode= setting to module while loading, like::
+
+	insmod dmfe mode=0 # Force 10M Half Duplex
+	insmod dmfe mode=1 # Force 100M Half Duplex
+	insmod dmfe mode=4 # Force 10M Full Duplex
+	insmod dmfe mode=5 # Force 100M Full Duplex
+
+Next you should configure your network interface with a command similar to::
+
+	ifconfig eth0 172.22.3.18
+		      ^^^^^^^^^^^
+		     Your IP Address
+
+Then you may have to modify the default routing table with command::
+
+	route add default eth0
+
+
+Now your ethernet card should be up and running.

+7. Run ``netconfig`` or ``netconf`` to create configuration script ifcfg-eth0
+   located at /etc/sysconfig/network-scripts or create it manually.
+
+   [see - Configuration Script Sample]
+8. Driver will automatically load and configure at next boot time.
+
+Compiling the Driver
+====================
+In Linux, NIC drivers are most commonly configured as loadable modules.
+The approach of building a monolithic kernel has become obsolete. The driver
+can be compiled as part of a monolithic kernel, but is strongly discouraged.
+The remainder of this section assumes the driver is built as a loadable module.
+In the Linux environment, it is a good idea to rebuild the driver from the
+source instead of relying on a precompiled version. This approach provides
+better reliability since a precompiled driver might depend on libraries or
+kernel features that are not present in a given Linux installation.
+
+The 3 files necessary to build Linux device driver are dl2k.c, dl2k.h and
+Makefile. To compile, the Linux installation must include the gcc compiler,
+the kernel source, and the kernel headers. The Linux driver supports Linux
+Kernels 2.4.7. Copy the files to a directory and enter the following command
+to compile and link the driver:
+
+CD-ROM drive
+------------
+
+::
+
+    [root@XXX /] mkdir cdrom
+    [root@XXX /] mount -r -t iso9660 -o conv=auto /dev/cdrom /cdrom
+    [root@XXX /] cd root
+    [root@XXX /root] mkdir dl2k
+    [root@XXX /root] cd dl2k
+    [root@XXX dl2k] cp /cdrom/linux/dl2k.tgz /root/dl2k
+    [root@XXX dl2k] tar xfvz dl2k.tgz
+    [root@XXX dl2k] make all
+
+Floppy disc drive
+-----------------
+
+::
+
+    [root@XXX /] cd root
+    [root@XXX /root] mkdir dl2k
+    [root@XXX /root] cd dl2k
+    [root@XXX dl2k] mcopy a:/linux/dl2k.tgz /root/dl2k
+    [root@XXX dl2k] tar xfvz dl2k.tgz
+    [root@XXX dl2k] make all
+
+Installing the Driver
+=====================
+
+Manual Installation
+-------------------
+
+  Once the driver has been compiled, it must be loaded, enabled, and bound
+  to a protocol stack in order to establish network connectivity. To load a
+  module enter the command::
+
+    insmod dl2k.o
+
+  or::
+
+    insmod dl2k.o <optional parameter>	; add parameter
+
+---------------------------------------------------------
+
+  example::
+
+    insmod dl2k.o media=100mbps_hd
+
+   or::
+
+    insmod dl2k.o media=3
+
+   or::
+
+    insmod dl2k.o media=3,2	; for 2 cards
+
+---------------------------------------------------------
+
+  Please reference the list of the command line parameters supported by
+  the Linux device driver below.
+
+  The insmod command only loads the driver and gives it a name of the form
+  eth0, eth1, etc. To bring the NIC into an operational state,
+  it is necessary to issue the following command::
+
+    ifconfig eth0 up
+
+  Finally, to bind the driver to the active protocol (e.g., TCP/IP with
+  Linux), enter the following command::
+
+    ifup eth0
+
+  Note that this is meaningful only if the system can find a configuration
+  script that contains the necessary network information. A sample will be
+  given in the next paragraph.
+
+  The commands to unload a driver are as follows::
+
+    ifdown eth0
+    ifconfig eth0 down
+    rmmod dl2k.o
+
+  The following are the commands to list the currently loaded modules and
+  to see the current network configuration::
+
+    lsmod
+    ifconfig
+
+
+Automated Installation
+----------------------
+  This section describes how to install the driver such that it is
+  automatically loaded and configured at boot time. The following description
+  is based on a Red Hat 6.0/7.0 distribution, but it can easily be ported to
+  other distributions as well.
+
+Red Hat v6.x/v7.x
+-----------------
+  1. Copy dl2k.o to the network modules directory, typically
+     /lib/modules/2.x.x-xx/net or /lib/modules/2.x.x/kernel/drivers/net.
+  2. Locate the boot module configuration file, most commonly in the
+     /etc/modprobe.d/ directory. Add the following lines::
+
+	alias ethx dl2k
+	options dl2k <optional parameters>
+
+     where ethx will be eth0 if the NIC is the only ethernet adapter, eth1 if
+     one other ethernet adapter is installed, etc. Refer to the table in the
+     previous section for the list of optional parameters.
+  3. Locate the network configuration scripts, normally the
+     /etc/sysconfig/network-scripts directory, and create a configuration
+     script named ifcfg-ethx that contains network information.
+  4. Note that for most Linux distributions, Red Hat included, a configuration
+     utility with a graphical user interface is provided to perform steps 2
+     and 3 above.
+
+
+Parameter Description
+=====================
+You can install this driver without any additional parameter. However, if you
+are going to have extensive functions then it is necessary to set extra
+parameter. Below is a list of the command line parameters supported by the
+Linux device
+driver.
+
+
+===============================   ==============================================
+mtu=packet_size			  Specifies the maximum packet size. default
+				  is 1500.
+
+media=media_type		  Specifies the media type the NIC operates at.
+				  autosense	Autosensing active media.
+
+				  ===========	=========================
+				  10mbps_hd	10Mbps half duplex.
+				  10mbps_fd	10Mbps full duplex.
+				  100mbps_hd	100Mbps half duplex.
+				  100mbps_fd	100Mbps full duplex.
+				  1000mbps_fd	1000Mbps full duplex.
+				  1000mbps_hd	1000Mbps half duplex.
+				  0		Autosensing active media.
+				  1		10Mbps half duplex.
+				  2		10Mbps full duplex.
+				  3		100Mbps half duplex.
+				  4		100Mbps full duplex.
+				  5          	1000Mbps half duplex.
+				  6          	1000Mbps full duplex.
+				  ===========	=========================
+
+				  By default, the NIC operates at autosense.
+				  1000mbps_fd and 1000mbps_hd types are only
+				  available for fiber adapter.
+
+vlan=n				  Specifies the VLAN ID. If vlan=0, the
+				  Virtual Local Area Network (VLAN) function is
+				  disable.
+
+jumbo=[0|1]			  Specifies the jumbo frame support. If jumbo=1,
+				  the NIC accept jumbo frames. By default, this
+				  function is disabled.
+				  Jumbo frame usually improve the performance
+				  int gigabit.
+				  This feature need jumbo frame compatible
+				  remote.
+
+rx_coalesce=m			  Number of rx frame handled each interrupt.
+rx_timeout=n			  Rx DMA wait time for an interrupt.
+				  If set rx_coalesce > 0, hardware only assert
+				  an interrupt for m frames. Hardware won't
+				  assert rx interrupt until m frames received or
+				  reach timeout of n * 640 nano seconds.
+				  Set proper rx_coalesce and rx_timeout can
+				  reduce congestion collapse and overload which
+				  has been a bottleneck for high speed network.
+
+				  For example, rx_coalesce=10 rx_timeout=800.
+				  that is, hardware assert only 1 interrupt
+				  for 10 frames received or timeout of 512 us.
+
+tx_coalesce=n			  Number of tx frame handled each interrupt.
+				  Set n > 1 can reduce the interrupts
+				  congestion usually lower performance of
+				  high speed network card. Default is 16.
+
+tx_flow=[1|0]			  Specifies the Tx flow control. If tx_flow=0,
+				  the Tx flow control disable else driver
+				  autodetect.
+rx_flow=[1|0]			  Specifies the Rx flow control. If rx_flow=0,
+				  the Rx flow control enable else driver
+				  autodetect.
+===============================   ==============================================
+
+
+Configuration Script Sample
+===========================
+Here is a sample of a simple configuration script::
+
+    DEVICE=eth0
+    USERCTL=no
+    ONBOOT=yes
+    POOTPROTO=none
+    BROADCAST=207.200.5.255
+    NETWORK=207.200.5.0
+    NETMASK=255.255.255.0
+    IPADDR=207.200.5.2
+
+
+Troubleshooting
+===============
+Q1. Source files contain ^ M behind every line.
+
+    Make sure all files are Unix file format (no LF). Try the following
+    shell command to convert files::
+
+	cat dl2k.c | col -b > dl2k.tmp
+	mv dl2k.tmp dl2k.c
+
+    OR::
+
+	cat dl2k.c | tr -d "\r" > dl2k.tmp
+	mv dl2k.tmp dl2k.c
+
+Q2: Could not find header files (``*.h``)?
+
+    To compile the driver, you need kernel header files. After
+    installing the kernel source, the header files are usually located in
+    /usr/src/linux/include, which is the default include directory configured
+    in Makefile. For some distributions, there is a copy of header files in
+    /usr/src/include/linux and /usr/src/include/asm, that you can change the
+    INCLUDEDIR in Makefile to /usr/include without installing kernel source.
+
+    Note that RH 7.0 didn't provide correct header files in /usr/include,
+    including those files will make a wrong version driver.

+DPAA Ethernet Overview
+======================
+
+DPAA stands for Data Path Acceleration Architecture and it is a
+set of networking acceleration IPs that are available on several
+generations of SoCs, both on PowerPC and ARM64.
+
+The Freescale DPAA architecture consists of a series of hardware blocks
+that support Ethernet connectivity. The Ethernet driver depends upon the
+following drivers in the Linux kernel:
+
+ - Peripheral Access Memory Unit (PAMU) (* needed only for PPC platforms)
+    drivers/iommu/fsl_*
+ - Frame Manager (FMan)
+    drivers/net/ethernet/freescale/fman
+ - Queue Manager (QMan), Buffer Manager (BMan)
+    drivers/soc/fsl/qbman

+
+Configuring DPAA Ethernet in your kernel
+========================================
+
+To enable the DPAA Ethernet driver, the following Kconfig options are required::
+
+  # common for arch/arm64 and arch/powerpc platforms
+  CONFIG_FSL_DPAA=y
+  CONFIG_FSL_FMAN=y
+  CONFIG_FSL_DPAA_ETH=y
+  CONFIG_FSL_XGMAC_MDIO=y
+
+  # for arch/powerpc only
+  CONFIG_FSL_PAMU=y
+
+  # common options needed for the PHYs used on the RDBs
+  CONFIG_VITESSE_PHY=y
+  CONFIG_REALTEK_PHY=y
+  CONFIG_AQUANTIA_PHY=y
+
+DPAA Ethernet Frame Processing
+==============================
+
+On Rx, buffers for the incoming frames are retrieved from the buffers found
+in the dedicated interface buffer pool. The driver initializes and seeds these
+with one page buffers.
+
+On Tx, all transmitted frames are returned to the driver through Tx
+confirmation frame queues. The driver is then responsible for freeing the
+buffers. In order to do this properly, a backpointer is added to the buffer
+before transmission that points to the skb. When the buffer returns to the
+driver on a confirmation FQ, the skb can be correctly consumed.
+
+DPAA Ethernet Features
+======================
+
+Currently the DPAA Ethernet driver enables the basic features required for
+a Linux Ethernet driver. The support for advanced features will be added
+gradually.
+
+The driver has Rx and Tx checksum offloading for UDP and TCP. Currently the Rx
+checksum offload feature is enabled by default and cannot be controlled through
+ethtool. Also, rx-flow-hash and rx-hashing was added. The addition of RSS
+provides a big performance boost for the forwarding scenarios, allowing
+different traffic flows received by one interface to be processed by different
+CPUs in parallel.
+
+The driver has support for multiple prioritized Tx traffic classes. Priorities
+range from 0 (lowest) to 3 (highest). These are mapped to HW workqueues with
+strict priority levels. Each traffic class contains NR_CPU TX queues. By
+default, only one traffic class is enabled and the lowest priority Tx queues
+are used. Higher priority traffic classes can be enabled with the mqprio
+qdisc. For example, all four traffic classes are enabled on an interface with
+the following command. Furthermore, skb priority levels are mapped to traffic
+classes as follows:
+
+	* priorities 0 to 3 - traffic class 0 (low priority)
+	* priorities 4 to 7 - traffic class 1 (medium-low priority)
+	* priorities 8 to 11 - traffic class 2 (medium-high priority)
+	* priorities 12 to 15 - traffic class 3 (high priority)
+
+::
+
+  tc qdisc add dev <int> root handle 1: \
+	 mqprio num_tc 4 map 0 0 0 0 1 1 1 1 2 2 2 2 3 3 3 3 hw 1
+
+DPAA IRQ Affinity and Receive Side Scaling
+==========================================
+
+Traffic coming on the DPAA Rx queues or on the DPAA Tx confirmation
+queues is seen by the CPU as ingress traffic on a certain portal.
+The DPAA QMan portal interrupts are affined each to a certain CPU.
+The same portal interrupt services all the QMan portal consumers.
+
+By default the DPAA Ethernet driver enables RSS, making use of the
+DPAA FMan Parser and Keygen blocks to distribute traffic on 128
+hardware frame queues using a hash on IP v4/v6 source and destination
+and L4 source and destination ports, in present in the received frame.
+When RSS is disabled, all traffic received by a certain interface is
+received on the default Rx frame queue. The default DPAA Rx frame
+queues are configured to put the received traffic into a pool channel
+that allows any available CPU portal to dequeue the ingress traffic.
+The default frame queues have the HOLDACTIVE option set, ensuring that
+traffic bursts from a certain queue are serviced by the same CPU.
+This ensures a very low rate of frame reordering. A drawback of this
+is that only one CPU at a time can service the traffic received by a
+certain interface when RSS is not enabled.
+
+To implement RSS, the DPAA Ethernet driver allocates an extra set of
+128 Rx frame queues that are configured to dedicated channels, in a
+round-robin manner. The mapping of the frame queues to CPUs is now
+hardcoded, there is no indirection table to move traffic for a certain
+FQ (hash result) to another CPU. The ingress traffic arriving on one
+of these frame queues will arrive at the same portal and will always
+be processed by the same CPU. This ensures intra-flow order preservation
+and workload distribution for multiple traffic flows.
+
+RSS can be turned off for a certain interface using ethtool, i.e.::
+
+	# ethtool -N fm1-mac9 rx-flow-hash tcp4 ""
+
+To turn it back on, one needs to set rx-flow-hash for tcp4/6 or udp4/6::
+
+	# ethtool -N fm1-mac9 rx-flow-hash udp4 sfdn
+
+There is no independent control for individual protocols, any command
+run for one of tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 is
+going to control the rx-flow-hashing for all protocols on that interface.
+
+Besides using the FMan Keygen computed hash for spreading traffic on the
+128 Rx FQs, the DPAA Ethernet driver also sets the skb hash value when
+the NETIF_F_RXHASH feature is on (active by default). This can be turned
+on or off through ethtool, i.e.::
+
+	# ethtool -K fm1-mac9 rx-hashing off
+	# ethtool -k fm1-mac9 | grep hash
+	receive-hashing: off
+	# ethtool -K fm1-mac9 rx-hashing on
+	Actual changes:
+	receive-hashing: on
+	# ethtool -k fm1-mac9 | grep hash
+	receive-hashing: on
+
+Please note that Rx hashing depends upon the rx-flow-hashing being on
+for that interface - turning off rx-flow-hashing will also disable the
+rx-hashing (without ethtool reporting it as off as that depends on the
+NETIF_F_RXHASH feature flag).
+
+Debugging
+=========
+
+The following statistics are exported for each interface through ethtool:
+
+	- interrupt count per CPU
+	- Rx packets count per CPU
+	- Tx packets count per CPU
+	- Tx confirmed packets count per CPU
+	- Tx S/G frames count per CPU
+	- Tx error count per CPU
+	- Rx error count per CPU
+	- Rx error count per type
+	- congestion related statistics:
+
+		- congestion status
+		- time spent in congestion
+		- number of time the device entered congestion
+		- dropped packets count per cause
+
+The driver also exports the following information in sysfs:
+
+	- the FQ IDs for each FQ type
+	  /sys/devices/platform/soc/<addr>.fman/<addr>.ethernet/dpaa-ethernet.<id>/net/fm<nr>-mac<nr>/fqids
+
+	- the ID of the buffer pool in use
+	  /sys/devices/platform/soc/<addr>.fman/<addr>.ethernet/dpaa-ethernet.<id>/net/fm<nr>-mac<nr>/bpids

+DPAA2 DPIO (Data Path I/O) Overview
+===================================

+
+This document provides an overview of the Freescale DPAA2 DPIO
+drivers
+
+Introduction
+============
+
+A DPAA2 DPIO (Data Path I/O) is a hardware object that provides
+interfaces to enqueue and dequeue frames to/from network interfaces
+and other accelerators.  A DPIO also provides hardware buffer
+pool management for network interfaces.
+
+This document provides an overview the Linux DPIO driver, its
+subcomponents, and its APIs.
+
+See
+Documentation/networking/device_drivers/ethernet/freescale/dpaa2/overview.rst
+for a general overview of DPAA2 and the general DPAA2 driver architecture
+in Linux.
+
+Driver Overview
+---------------
+
+The DPIO driver is bound to DPIO objects discovered on the fsl-mc bus and
+provides services that:
+
+  A. allow other drivers, such as the Ethernet driver, to enqueue and dequeue
+     frames for their respective objects
+  B. allow drivers to register callbacks for data availability notifications
+     when data becomes available on a queue or channel
+  C. allow drivers to manage hardware buffer pools
+
+The Linux DPIO driver consists of 3 primary components--
+   DPIO object driver-- fsl-mc driver that manages the DPIO object
+
+   DPIO service-- provides APIs to other Linux drivers for services
+
+   QBman portal interface-- sends portal commands, gets responses::

+
+
+DPIO Object Driver (dpio-driver.c)
+----------------------------------
+
+   The dpio-driver component registers with the fsl-mc bus to handle objects of
+   type "dpio".  The implementation of probe() handles basic initialization
+   of the DPIO including mapping of the DPIO regions (the QBman SW portal)
+   and initializing interrupts and registering irq handlers.  The dpio-driver
+   registers the probed DPIO with dpio-service.
+
+DPIO service  (dpio-service.c, dpaa2-io.h)
+------------------------------------------
+
+   The dpio service component provides queuing, notification, and buffers
+   management services to DPAA2 drivers, such as the Ethernet driver.  A system
+   will typically allocate 1 DPIO object per CPU to allow queuing operations
+   to happen simultaneously across all CPUs.

+
+      dpaa2_io_service_acquire()
+
+QBman portal interface (qbman-portal.c)
+---------------------------------------
+
+   The qbman-portal component provides APIs to do the low level hardware
+   bit twiddling for operations such as:
+
+      - initializing Qman software portals
+      - building and sending portal commands
+      - portal interrupt configuration and processing
+
+   The qbman-portal APIs are not public to other drivers, and are
+   only used by dpio-service.
+
+Other (dpaa2-fd.h, dpaa2-global.h)
+----------------------------------
+
+   Frame descriptor and scatter-gather definitions and the APIs used to
+   manipulate them are defined in dpaa2-fd.h.
+
+   Dequeue result struct and parsing APIs are defined in dpaa2-global.h.

+DPAA2 Ethernet driver
+===============================
+
+:Copyright: |copy| 2017-2018 NXP
+
+This file provides documentation for the Freescale DPAA2 Ethernet driver.
+
+Supported Platforms
+===================
+This driver provides networking support for Freescale DPAA2 SoCs, e.g.
+LS2080A, LS2088A, LS1088A.
+
+
+Architecture Overview
+=====================
+Unlike regular NICs, in the DPAA2 architecture there is no single hardware block
+representing network interfaces; instead, several separate hardware resources
+concur to provide the networking functionality:
+
+- network interfaces
+- queues, channels
+- buffer pools
+- MAC/PHY
+
+All hardware resources are allocated and configured through the Management
+Complex (MC) portals. MC abstracts most of these resources as DPAA2 objects
+and exposes ABIs through which they can be configured and controlled. A few
+hardware resources, like queues, do not have a corresponding MC object and
+are treated as internal resources of other objects.
+
+For a more detailed description of the DPAA2 architecture and its object
+abstractions see
+*Documentation/networking/device_drivers/ethernet/freescale/dpaa2/overview.rst*.
+
+Each Linux net device is built on top of a Datapath Network Interface (DPNI)
+object and uses Buffer Pools (DPBPs), I/O Portals (DPIOs) and Concentrators
+(DPCONs).

+                                Channel
+
+Datapath I/O (DPIO) portals provide enqueue and dequeue services, data
+availability notifications and buffer pool management. DPIOs are shared between
+all DPAA2 objects (and implicitly all DPAA2 kernel drivers) that work with data
+frames, but must be affine to the CPUs for the purpose of traffic distribution.
+
+Frames are transmitted and received through hardware frame queues, which can be
+grouped in channels for the purpose of hardware scheduling. The Ethernet driver
+enqueues TX frames on egress queues and after transmission is complete a TX
+confirmation frame is sent back to the CPU.
+
+When frames are available on ingress queues, a data availability notification
+is sent to the CPU; notifications are raised per channel, so even if multiple
+queues in the same channel have available frames, only one notification is sent.
+After a channel fires a notification, is must be explicitly rearmed.
+
+Each network interface can have multiple Rx, Tx and confirmation queues affined
+to CPUs, and one channel (DPCON) for each CPU that services at least one queue.
+DPCONs are used to distribute ingress traffic to different CPUs via the cores'
+affine DPIOs.
+
+The role of hardware buffer pools is storage of ingress frame data. Each network
+interface has a privately owned buffer pool which it seeds with kernel allocated
+buffers.
+
+
+DPNIs are decoupled from PHYs; a DPNI can be connected to a PHY through a DPMAC
+object or to another DPNI through an internal link, but the connection is
+managed by MC and completely transparent to the Ethernet driver.

+
+Creating a Network Interface
+============================
+A net device is created for each DPNI object probed on the MC bus. Each DPNI has
+a number of properties which determine the network interface configuration
+options and associated hardware resources.
+
+DPNI objects (and the other DPAA2 objects needed for a network interface) can be
+added to a container on the MC bus in one of two ways: statically, through a
+Datapath Layout Binary file (DPL) that is parsed by MC at boot time; or created
+dynamically at runtime, via the DPAA2 objects APIs.
+
+
+Features & Offloads
+===================
+Hardware checksum offloading is supported for TCP and UDP over IPv4/6 frames.
+The checksum offloads can be independently configured on RX and TX through
+ethtool.
+
+Hardware offload of unicast and multicast MAC filtering is supported on the
+ingress path and permanently enabled.
+
+Scatter-gather frames are supported on both RX and TX paths. On TX, SG support
+is configurable via ethtool; on RX it is always enabled.
+
+The DPAA2 hardware can process jumbo Ethernet frames of up to 10K bytes.
+
+The Ethernet driver defines a static flow hashing scheme that distributes
+traffic based on a 5-tuple key: src IP, dst IP, IP proto, L4 src port,
+L4 dst port. No user configuration is supported for now.
+
+Hardware specific statistics for the network interface as well as some
+non-standard driver stats can be consulted through ethtool -S option.

+DPAA2 MAC / PHY support
+=======================
+
+:Copyright: |copy| 2019 NXP
+
+Overview
+--------
+
+The DPAA2 MAC / PHY support consists of a set of APIs that help DPAA2 network
+drivers (dpaa2-eth, dpaa2-ethsw) interract with the PHY library.
+
+DPAA2 Software Architecture
+---------------------------
+
+Among other DPAA2 objects, the fsl-mc bus exports DPNI objects (abstracting a
+network interface) and DPMAC objects (abstracting a MAC). The dpaa2-eth driver
+probes on the DPNI object and connects to and configures a DPMAC object with
+the help of phylink.
+
+Data connections may be established between a DPNI and a DPMAC, or between two
+DPNIs. Depending on the connection type, the netif_carrier_[on/off] is handled
+directly by the dpaa2-eth driver or by phylink.

+           +--------------------------------------+
+
+
+Depending on an MC firmware configuration setting, each MAC may be in one of two modes:
+
+- DPMAC_LINK_TYPE_FIXED: the link state management is handled exclusively by
+  the MC firmware by polling the MAC PCS. Without the need to register a
+  phylink instance, the dpaa2-eth driver will not bind to the connected dpmac
+  object at all.
+
+- DPMAC_LINK_TYPE_PHY: The MC firmware is left waiting for link state update
+  events, but those are in fact passed strictly between the dpaa2-mac (based on
+  phylink) and its attached net_device driver (dpaa2-eth, dpaa2-ethsw),
+  effectively bypassing the firmware.
+
+Implementation
+--------------
+
+At probe time or when a DPNI's endpoint is dynamically changed, the dpaa2-eth
+is responsible to find out if the peer object is a DPMAC and if this is the
+case, to integrate it with PHYLINK using the dpaa2_mac_connect() API, which
+will do the following:
+
+ - look up the device tree for PHYLINK-compatible of binding (phy-handle)
+ - will create a PHYLINK instance associated with the received net_device
+ - connect to the PHY using phylink_of_phy_connect()
+
+The following phylink_mac_ops callback are implemented:
+
+ - .validate() will populate the supported linkmodes with the MAC capabilities
+   only when the phy_interface_t is RGMII_* (at the moment, this is the only
+   link type supported by the driver).
+
+ - .mac_config() will configure the MAC in the new configuration using the
+   dpmac_set_link_state() MC firmware API.
+
+ - .mac_link_up() / .mac_link_down() will update the MAC link using the same
+   API described above.
+
+At driver unbind() or when the DPNI object is disconnected from the DPMAC, the
+dpaa2-eth driver calls dpaa2_mac_disconnect() which will, in turn, disconnect
+from the PHY and destroy the PHYLINK instance.
+
+In case of a DPNI-DPMAC connection, an 'ip link set dev eth0 up' would start
+the following sequence of operations:
+
+(1) phylink_start() called from .dev_open().
+(2) The .mac_config() and .mac_link_up() callbacks are called by PHYLINK.
+(3) In order to configure the HW MAC, the MC Firmware API
+    dpmac_set_link_state() is called.
+(4) The firmware will eventually setup the HW MAC in the new configuration.
+(5) A netif_carrier_on() call is made directly from PHYLINK on the associated
+    net_device.
+(6) The dpaa2-eth driver handles the LINK_STATE_CHANGE irq in order to
+    enable/disable Rx taildrop based on the pause frame settings.

+In case of a DPNI-DPNI connection, a usual sequence of operations looks like

+
+(1) ip link set dev eth0 up
+(2) The dpni_enable() MC API called on the associated fsl_mc_device.
+(3) ip link set dev eth1 up
+(4) The dpni_enable() MC API called on the associated fsl_mc_device.
+(5) The LINK_STATE_CHANGED irq is received by both instances of the dpaa2-eth
+    driver because now the operational link state is up.
+(6) The netif_carrier_on() is called on the exported net_device from
+    link_state_update().

+
+
+Exported API
+------------
+
+Any DPAA2 driver that drivers endpoints of DPMAC objects should service its
+_EVENT_ENDPOINT_CHANGED irq and connect/disconnect from the associated DPMAC
+when necessary using the below listed API::
+
+ - int dpaa2_mac_connect(struct dpaa2_mac *mac);
+ - void dpaa2_mac_disconnect(struct dpaa2_mac *mac);
+
+A phylink integration is necessary only when the partner DPMAC is not of TYPE_FIXED.
+One can check for this condition using the below API::
+
+ - bool dpaa2_mac_is_type_fixed(struct fsl_mc_device *dpmac_dev,struct fsl_mc_io *mc_io);
+
+Before connection to a MAC, the caller must allocate and populate the
+dpaa2_mac structure with the associated net_device, a pointer to the MC portal
+to be used and the actual fsl_mc_device structure of the DPMAC.

+DPAA2 (Data Path Acceleration Architecture Gen2) Overview
+=========================================================

+
+This document provides an overview of the Freescale DPAA2 architecture
+and how it is integrated into the Linux kernel.
+
+Introduction
+============
+
+DPAA2 is a hardware architecture designed for high-speeed network
+packet processing.  DPAA2 consists of sophisticated mechanisms for
+processing Ethernet packets, queue management, buffer management,
+autonomous L2 switching, virtual Ethernet bridging, and accelerator
+(e.g. crypto) sharing.
+
+A DPAA2 hardware component called the Management Complex (or MC) manages the
+DPAA2 hardware resources.  The MC provides an object-based abstraction for
+software drivers to use the DPAA2 hardware.
+The MC uses DPAA2 hardware resources such as queues, buffer pools, and
+network ports to create functional objects/devices such as network
+interfaces, an L2 switch, or accelerator instances.
+The MC provides memory-mapped I/O command interfaces (MC portals)
+which DPAA2 software drivers use to operate on DPAA2 objects.
+
+The diagram below shows an overview of the DPAA2 resource management
+architecture::

+
+
+The MC mediates operations such as create, discover,
+connect, configuration, and destroy.  Fast-path operations
+on data, such as packet transmit/receive, are not mediated by
+the MC and are done directly using memory mapped regions in
+DPIO objects.
+
+Overview of DPAA2 Objects
+=========================
+
+The section provides a brief overview of some key DPAA2 objects.
+A simple scenario is described illustrating the objects involved
+in creating a network interfaces.
+
+DPRC (Datapath Resource Container)
+----------------------------------
+
+A DPRC is a container object that holds all the other
+types of DPAA2 objects.  In the example diagram below there
+are 8 objects of 5 types (DPMCP, DPIO, DPBP, DPNI, and DPMAC)
+in the container.
+
+::
+
+	+---------------------------------------------------------+
+	| DPRC                                                    |
+	|                                                         |
+	|  +-------+  +-------+  +-------+  +-------+  +-------+  |
+	|  | DPMCP |  | DPIO  |  | DPBP  |  | DPNI  |  | DPMAC |  |
+	|  +-------+  +-------+  +-------+  +---+---+  +---+---+  |
+	|  | DPMCP |  | DPIO  |                                   |
+	|  +-------+  +-------+                                   |
+	|  | DPMCP |                                              |
+	|  +-------+                                              |
+	|                                                         |
+	+---------------------------------------------------------+
+
+From the point of view of an OS, a DPRC behaves similar to a plug and
+play bus, like PCI.  DPRC commands can be used to enumerate the contents
+of the DPRC, discover the hardware objects present (including mappable
+regions and interrupts).
+
+::
+
+	DPRC.1 (bus)
+	   |
+	   +--+--------+-------+-------+-------+
+	      |        |       |       |       |
+	    DPMCP.1  DPIO.1  DPBP.1  DPNI.1  DPMAC.1
+	    DPMCP.2  DPIO.2
+	    DPMCP.3
+
+Hardware objects can be created and destroyed dynamically, providing
+the ability to hot plug/unplug objects in and out of the DPRC.
+
+A DPRC has a mappable MMIO region (an MC portal) that can be used
+to send MC commands.  It has an interrupt for status events (like
+hotplug).
+All objects in a container share the same hardware "isolation context".
+This means that with respect to an IOMMU the isolation granularity
+is at the DPRC (container) level, not at the individual object
+level.
+
+DPRCs can be defined statically and populated with objects
+via a config file passed to the MC when firmware starts it.
+
+DPAA2 Objects for an Ethernet Network Interface
+-----------------------------------------------
+
+A typical Ethernet NIC is monolithic-- the NIC device contains TX/RX
+queuing mechanisms, configuration mechanisms, buffer management,
+physical ports, and interrupts.  DPAA2 uses a more granular approach
+utilizing multiple hardware objects.  Each object provides specialized
+functions. Groups of these objects are used by software to provide
+Ethernet network interface functionality.  This approach provides
+efficient use of finite hardware resources, flexibility, and
+performance advantages.
+
+The diagram below shows the objects needed for a simple
+network interface configuration on a system with 2 CPUs.
+
+::
+
+	+---+---+ +---+---+
+	   CPU0     CPU1

+	   +---+---+
+	     DPMAC
+	   +---+---+
+	       |
+	   port/PHY
+
+Below the objects are described.  For each object a brief description
+is provided along with a summary of the kinds of operations the object
+supports and a summary of key resources of the object (MMIO regions
+and IRQs).
+
+DPMAC (Datapath Ethernet MAC)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Represents an Ethernet MAC, a hardware device that connects to an Ethernet
+PHY and allows physical transmission and reception of Ethernet frames.
+
+- MMIO regions: none
+- IRQs: DPNI link change
+- commands: set link up/down, link config, get stats,
+  IRQ config, enable, reset
+
+DPNI (Datapath Network Interface)
+Contains TX/RX queues, network interface configuration, and RX buffer pool
+configuration mechanisms.  The TX/RX queues are in memory and are identified
+by queue number.
+
+- MMIO regions: none
+- IRQs: link state
+- commands: port config, offload config, queue config,
+  parse/classify config, IRQ config, enable, reset
+
+DPIO (Datapath I/O)
+~~~~~~~~~~~~~~~~~~~
+Provides interfaces to enqueue and dequeue
+packets and do hardware buffer pool management operations.  The DPAA2
+architecture separates the mechanism to access queues (the DPIO object)
+from the queues themselves.  The DPIO provides an MMIO interface to
+enqueue/dequeue packets.  To enqueue something a descriptor is written
+to the DPIO MMIO region, which includes the target queue number.
+There will typically be one DPIO assigned to each CPU.  This allows all
+CPUs to simultaneously perform enqueue/dequeued operations.  DPIOs are
+expected to be shared by different DPAA2 drivers.
+
+- MMIO regions: queue operations, buffer management
+- IRQs: data availability, congestion notification, buffer
+  pool depletion
+- commands: IRQ config, enable, reset
+
+DPBP (Datapath Buffer Pool)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Represents a hardware buffer pool.
+
+- MMIO regions: none
+- IRQs: none
+- commands: enable, reset
+
+DPMCP (Datapath MC Portal)
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+Provides an MC command portal.
+Used by drivers to send commands to the MC to manage
+objects.
+
+- MMIO regions: MC command portal
+- IRQs: command completion
+- commands: IRQ config, enable, reset
+
+Object Connections
+==================
+Some objects have explicit relationships that must
+be configured:
+
+- DPNI <--> DPMAC
+- DPNI <--> DPNI
+- DPNI <--> L2-switch-port
+
+    A DPNI must be connected to something such as a DPMAC,
+    another DPNI, or L2 switch port.  The DPNI connection
+    is made via a DPRC command.
+
+::
+
+              +-------+  +-------+
+              | DPNI  |  | DPMAC |
+              +---+---+  +---+---+
+                  |          |
+                  +==========+
+
+- DPNI <--> DPBP
+
+    A network interface requires a 'buffer pool' (DPBP
+    object) which provides a list of pointers to memory
+    where received Ethernet data is to be copied.  The
+    Ethernet driver configures the DPBPs associated with
+    the network interface.
+
+Interrupts
+==========
+All interrupts generated by DPAA2 objects are message
+interrupts.  At the hardware level message interrupts
+generated by devices will normally have 3 components--
+1) a non-spoofable 'device-id' expressed on the hardware
+bus, 2) an address, 3) a data value.
+
+In the case of DPAA2 devices/objects, all objects in the
+same container/DPRC share the same 'device-id'.
+For ARM-based SoC this is the same as the stream ID.
+
+
+DPAA2 Linux Drivers Overview
+============================
+
+This section provides an overview of the Linux kernel drivers for
+DPAA2-- 1) the bus driver and associated "DPAA2 infrastructure"
+drivers and 2) functional object drivers (such as Ethernet).
+
+As described previously, a DPRC is a container that holds the other
+types of DPAA2 objects.  It is functionally similar to a plug-and-play
+bus controller.
+Each object in the DPRC is a Linux "device" and is bound to a driver.
+The diagram below shows the Linux drivers involved in a networking
+scenario and the objects bound to each driver.  A brief description
+of each driver follows.

+	============================================|========================
+
+A brief description of each driver is provided below.
+
+MC-bus driver
+-------------
+The MC-bus driver is a platform driver and is probed from a
+node in the device tree (compatible "fsl,qoriq-mc") passed in by boot
+firmware.  It is responsible for bootstrapping the DPAA2 kernel
+infrastructure.
+Key functions include:
+
+- registering a new bus type named "fsl-mc" with the kernel,
+  and implementing bus call-backs (e.g. match/uevent/dev_groups)
+- implementing APIs for DPAA2 driver registration and for device
+  add/remove
+- creates an MSI IRQ domain
+- doing a 'device add' to expose the 'root' DPRC, in turn triggering
+  a bind of the root DPRC to the DPRC driver
+
+The binding for the MC-bus device-tree node can be consulted at
+*Documentation/devicetree/bindings/misc/fsl,qoriq-mc.txt*.
+The sysfs bind/unbind interfaces for the MC-bus can be consulted at
+*Documentation/ABI/testing/sysfs-bus-fsl-mc*.
+
+DPRC driver
+-----------
+The DPRC driver is bound to DPRC objects and does runtime management
+of a bus instance.  It performs the initial bus scan of the DPRC
+and handles interrupts for container events such as hot plug by
+re-scanning the DPRC.
+
+Allocator
+---------
+Certain objects such as DPMCP and DPBP are generic and fungible,
+and are intended to be used by other drivers.  For example,
+the DPAA2 Ethernet driver needs:
+
+- DPMCPs to send MC commands, to configure network interfaces
+- DPBPs for network buffer pools
+
+The allocator driver registers for these allocatable object types
+and those objects are bound to the allocator when the bus is probed.
+The allocator maintains a pool of objects that are available for
+allocation by other DPAA2 drivers.
+
+DPIO driver
+-----------
+The DPIO driver is bound to DPIO objects and provides services that allow
+other drivers such as the Ethernet driver to enqueue and dequeue data for
+their respective objects.
+Key services include:
+
+- data availability notifications
+- hardware queuing operations (enqueue and dequeue of data)
+- hardware buffer pool management
+
+To transmit a packet the Ethernet driver puts data on a queue and
+invokes a DPIO API.  For receive, the Ethernet driver registers
+a data availability notification callback.  To dequeue a packet
+a DPIO API is used.
+There is typically one DPIO object per physical CPU for optimum
+performance, allowing different CPUs to simultaneously enqueue
+and dequeue data.
+
+The DPIO driver operates on behalf of all DPAA2 drivers
+active in the kernel--  Ethernet, crypto, compression,
+etc.
+
+Ethernet driver
+---------------
+The Ethernet driver is bound to a DPNI and implements the kernel
+interfaces needed to connect the DPAA2 network interface to
+the network stack.
+Each DPNI corresponds to a Linux network interface.
+
+MAC driver
+----------
+An Ethernet PHY is an off-chip, board specific component and is managed
+by the appropriate PHY driver via an mdio bus.  The MAC driver
+plays a role of being a proxy between the PHY driver and the
+MC.  It does this proxy via the MC commands to a DPMAC object.
+If the PHY driver signals a link change, the MAC driver notifies
+the MC via a DPMAC command.  If a network interface is brought
+up or down, the MC notifies the DPMAC driver via an interrupt and
+the driver can take appropriate action.

+===========================
+The Gianfar Ethernet Driver
+===========================
+
+:Author: Andy Fleming <afleming@freescale.com>
+:Updated: 2005-07-28
+
+
+Checksum Offloading
+===================
+
+The eTSEC controller (first included in parts from late 2005 like
+the 8548) has the ability to perform TCP, UDP, and IP checksums
+in hardware.  The Linux kernel only offloads the TCP and UDP
+checksums (and always performs the pseudo header checksums), so
+the driver only supports checksumming for TCP/IP and UDP/IP
+packets.  Use ethtool to enable or disable this feature for RX
+and TX.
+
+VLAN
+====
+
+In order to use VLAN, please consult Linux documentation on
+configuring VLANs.  The gianfar driver supports hardware insertion and
+extraction of VLAN headers, but not filtering.  Filtering will be
+done by the kernel.
+
+Multicasting
+============
+
+The gianfar driver supports using the group hash table on the
+TSEC (and the extended hash table on the eTSEC) for multicast
+filtering.  On the eTSEC, the exact-match MAC registers are used
+before the hash tables.  See Linux documentation on how to join
+multicast groups.
+
+Padding
+=======
+
+The gianfar driver supports padding received frames with 2 bytes
+to align the IP header to a 16-byte boundary, when supported by
+hardware.
+
+Ethtool
+=======
+
+The gianfar driver supports the use of ethtool for many
+configuration options.  You must run ethtool only on currently
+open interfaces.  See ethtool documentation for details.

+PCI Bars
+========
+The gVNIC PCI device exposes three 32-bit memory BARS:
+- Bar0 - Device configuration and status registers.
+- Bar1 - MSI-X vector table
+- Bar2 - IRQ, RX and TX doorbells
+
+Device Interactions
+===================
+The driver interacts with the device in the following ways:
+ - Registers
+    - A block of MMIO registers
+    - See gve_register.h for more detail
+ - Admin Queue
+    - See description below
+ - Reset
+    - At any time the device can be reset
+ - Interrupts
+    - See supported interrupts below
+ - Transmit and Receive Queues
+    - See description below
+
+Registers
+---------
+All registers are MMIO and big endian.
+
+The registers are used for initializing and configuring the device as well as
+querying device status in response to management interrupts.
+
+Admin Queue (AQ)
+----------------
+The Admin Queue is a PAGE_SIZE memory block, treated as an array of AQ
+commands, used by the driver to issue commands to the device and set up
+resources.The driver and the device maintain a count of how many commands
+have been submitted and executed. To issue AQ commands, the driver must do
+the following (with proper locking):
+
+1)  Copy new commands into next available slots in the AQ array
+2)  Increment its counter by he number of new commands
+3)  Write the counter into the GVE_ADMIN_QUEUE_DOORBELL register
+4)  Poll the ADMIN_QUEUE_EVENT_COUNTER register until it equals
+    the value written to the doorbell, or until a timeout.
+
+The device will update the status field in each AQ command reported as
+executed through the ADMIN_QUEUE_EVENT_COUNTER register.
+
+Device Resets
+-------------
+A device reset is triggered by writing 0x0 to the AQ PFN register.
+This causes the device to release all resources allocated by the
+driver, including the AQ itself.
+
+Interrupts
+----------
+The following interrupts are supported by the driver:
+
+Management Interrupt
+~~~~~~~~~~~~~~~~~~~~
+The management interrupt is used by the device to tell the driver to
+look at the GVE_DEVICE_STATUS register.
+
+The handler for the management irq simply queues the service task in
+the workqueue to check the register and acks the irq.
+
+Notification Block Interrupts
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The notification block interrupts are used to tell the driver to poll
+the queues associated with that interrupt.
+
+The handler for these irqs schedule the napi for that block to run
+and poll the queues.
+
+Traffic Queues
+--------------
+gVNIC's queues are composed of a descriptor ring and a buffer and are
+assigned to a notification block.
+
+The descriptor rings are power-of-two-sized ring buffers consisting of
+fixed-size descriptors. They advance their head pointer using a __be32
+doorbell located in Bar2. The tail pointers are advanced by consuming
+descriptors in-order and updating a __be32 counter. Both the doorbell
+and the counter overflow to zero.
+
+Each queue's buffers must be registered in advance with the device as a
+queue page list, and packet data can only be put in those pages.
+
+Transmit
+~~~~~~~~
+gve maps the buffers for transmit rings into a FIFO and copies the packets
+into the FIFO before sending them to the NIC.
+
+Receive
+~~~~~~~
+The buffers for receive rings are put into a data ring that is the same
+length as the descriptor ring and the head and tail pointers advance over
+the rings together.

+In This Release
+===============
+
+This file describes the Linux Base Driver for the Intel(R) PRO/100 Family of
+Adapters. This driver includes support for Itanium(R)2-based systems.
+
+For questions related to hardware requirements, refer to the documentation
+supplied with your Intel PRO/100 adapter.
+
+The following features are now available in supported kernels:
+ - Native VLANs
+ - Channel Bonding (teaming)
+ - SNMP
+
+Channel Bonding documentation can be found in the Linux kernel source:
+/Documentation/networking/bonding.rst
+
+
+Identifying Your Adapter
+========================
+
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+Driver Configuration Parameters
+===============================
+
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+Rx Descriptors:
+   Number of receive descriptors. A receive descriptor is a data
+   structure that describes a receive buffer and its attributes to the network
+   controller. The data in the descriptor is used by the controller to write
+   data from the controller to host memory. In the 3.x.x driver the valid range
+   for this parameter is 64-256. The default value is 256. This parameter can be
+   changed using the command::
+
+     ethtool -G eth? rx n
+
+   Where n is the number of desired Rx descriptors.
+
+Tx Descriptors:
+   Number of transmit descriptors. A transmit descriptor is a data
+   structure that describes a transmit buffer and its attributes to the network
+   controller. The data in the descriptor is used by the controller to read
+   data from the host memory to the controller. In the 3.x.x driver the valid
+   range for this parameter is 64-256. The default value is 128. This parameter
+   can be changed using the command::
+
+     ethtool -G eth? tx n
+
+   Where n is the number of desired Tx descriptors.
+
+Speed/Duplex:
+   The driver auto-negotiates the link speed and duplex settings by
+   default. The ethtool utility can be used as follows to force speed/duplex.::
+
+     ethtool -s eth?  autoneg off speed {10|100} duplex {full|half}
+
+   NOTE: setting the speed/duplex to incorrect values will cause the link to
+   fail.
+
+Event Log Message Level:
+   The driver uses the message level flag to log events
+   to syslog. The message level can be set at driver load time. It can also be
+   set using the command::
+
+     ethtool -s eth? msglvl n
+
+
+Additional Configurations
+=========================
+
+Configuring the Driver on Different Distributions
+-------------------------------------------------
+
+Configuring a network driver to load properly when the system is started
+is distribution dependent.  Typically, the configuration process involves
+adding an alias line to `/etc/modprobe.d/*.conf` as well as editing other
+system startup scripts and/or configuration files.  Many popular Linux
+distributions ship with tools to make these changes for you.  To learn
+the proper way to configure a network device for your system, refer to
+your distribution documentation.  If during this process you are asked
+for the driver or module name, the name for the Linux Base Driver for
+the Intel PRO/100 Family of Adapters is e100.
+
+As an example, if you install the e100 driver for two PRO/100 adapters
+(eth0 and eth1), add the following to a configuration file in
+/etc/modprobe.d/::
+
+       alias eth0 e100
+       alias eth1 e100
+
+Viewing Link Messages
+---------------------
+
+In order to see link messages and other Intel driver information on your
+console, you must set the dmesg level up to six.  This can be done by
+entering the following on the command line before loading the e100
+driver::
+
+       dmesg -n 6
+
+If you wish to see all messages issued by the driver, including debug
+messages, set the dmesg level to eight.
+
+NOTE: This setting is not saved across reboots.
+
+ethtool
+-------
+
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information.  The ethtool
+version 1.6 or later is required for this functionality.
+
+The latest release of ethtool can be found from
+https://www.kernel.org/pub/software/network/ethtool/
+
+Enabling Wake on LAN (WoL)
+--------------------------
+WoL is provided through the ethtool utility.  For instructions on
+enabling WoL with ethtool, refer to the ethtool man page.  WoL will be
+enabled on the system during the next shut down or reboot.  For this
+driver version, in order to enable WoL, the e100 driver must be loaded
+when shutting down or rebooting the system.
+
+NAPI
+----
+
+NAPI (Rx polling mode) is supported in the e100 driver.
+
+See https://wiki.linuxfoundation.org/networking/napi for more
+information on NAPI.
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+
+Due to the default ARP behavior on Linux, it is not possible to have one
+system on two IP networks in the same Ethernet broadcast domain
+(non-partitioned switch) behave as expected.  All Ethernet interfaces
+will respond to IP traffic for any IP address assigned to the system.
+This results in unbalanced receive traffic.
+
+If you have multiple interfaces in a server, either turn on ARP
+filtering by
+
+(1) entering::
+
+	echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+
+    (this only works if your kernel's version is higher than 2.4.5), or
+
+(2) installing the interfaces in separate broadcast domains (either
+    in different switches or in a switch partitioned to VLANs).

+Driver ID Guide at:
+
+    http://support.intel.com/support/go/network/adapter/idguide.htm
+
+For the latest Intel network drivers for Linux, refer to the following

+networking link on the left to search for your adapter:
+
+    http://support.intel.com/support/go/network/adapter/home.htm
+
+Command Line Parameters
+=======================
+
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+NOTES:
+	For more information about the AutoNeg, Duplex, and Speed
+        parameters, see the "Speed and Duplex Configuration" section in
+        this document.
+
+        For more information about the InterruptThrottleRate,
+        RxIntDelay, TxIntDelay, RxAbsIntDelay, and TxAbsIntDelay
+        parameters, see the application note at:
+        http://www.intel.com/design/network/applnots/ap450.htm
+
+AutoNeg
+-------
+
+(Supported only on adapters with copper connections)
+
+:Valid Range:   0x01-0x0F, 0x20-0x2F
+:Default Value: 0x2F
+
+This parameter is a bit-mask that specifies the speed and duplex settings
+advertised by the adapter.  When this parameter is used, the Speed and
+Duplex parameters must not be specified.
+
+NOTE:
+       Refer to the Speed and Duplex section of this readme for more
+       information on the AutoNeg parameter.
+
+Duplex
+------
+
+(Supported only on adapters with copper connections)
+
+:Valid Range:   0-2 (0=auto-negotiate, 1=half, 2=full)
+:Default Value: 0
+
+This defines the direction in which data is allowed to flow.  Can be
+either one or two-directional.  If both Duplex and the link partner are
+set to auto-negotiate, the board auto-detects the correct duplex.  If the
+link partner is forced (either full or half), Duplex defaults to half-
+duplex.
+
+FlowControl
+-----------
+
+:Valid Range:   0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
+:Default Value: Reads flow control settings from the EEPROM
+
+This parameter controls the automatic generation(Tx) and response(Rx)
+to Ethernet PAUSE frames.
+
+InterruptThrottleRate
+---------------------
+
+(not supported on Intel(R) 82542, 82543 or 82544-based adapters)
+
+:Valid Range:
+   0,1,3,4,100-100000 (0=off, 1=dynamic, 3=dynamic conservative,
+   4=simplified balancing)
+:Default Value: 3
+
+The driver can limit the amount of interrupts per second that the adapter
+will generate for incoming packets. It does this by writing a value to the
+adapter that is based on the maximum amount of interrupts that the adapter
+will generate per second.
+
+Setting InterruptThrottleRate to a value greater or equal to 100
+will program the adapter to send out a maximum of that many interrupts
+per second, even if more packets have come in. This reduces interrupt
+load on the system and can lower CPU utilization under heavy load,
+but will increase latency as packets are not processed as quickly.
+
+The default behaviour of the driver previously assumed a static
+InterruptThrottleRate value of 8000, providing a good fallback value for
+all traffic types,but lacking in small packet performance and latency.
+The hardware can handle many more small packets per second however, and
+for this reason an adaptive interrupt moderation algorithm was implemented.
+
+Since 7.3.x, the driver has two adaptive modes (setting 1 or 3) in which
+it dynamically adjusts the InterruptThrottleRate value based on the traffic
+that it receives. After determining the type of incoming traffic in the last
+timeframe, it will adjust the InterruptThrottleRate to an appropriate value
+for that traffic.
+
+The algorithm classifies the incoming traffic every interval into
+classes.  Once the class is determined, the InterruptThrottleRate value is
+adjusted to suit that traffic type the best. There are three classes defined:
+"Bulk traffic", for large amounts of packets of normal size; "Low latency",
+for small amounts of traffic and/or a significant percentage of small
+packets; and "Lowest latency", for almost completely small packets or
+minimal traffic.
+
+In dynamic conservative mode, the InterruptThrottleRate value is set to 4000
+for traffic that falls in class "Bulk traffic". If traffic falls in the "Low
+latency" or "Lowest latency" class, the InterruptThrottleRate is increased
+stepwise to 20000. This default mode is suitable for most applications.
+
+For situations where low latency is vital such as cluster or
+grid computing, the algorithm can reduce latency even more when
+InterruptThrottleRate is set to mode 1. In this mode, which operates
+the same as mode 3, the InterruptThrottleRate will be increased stepwise to
+70000 for traffic in class "Lowest latency".
+
+In simplified mode the interrupt rate is based on the ratio of TX and
+RX traffic.  If the bytes per second rate is approximately equal, the
+interrupt rate will drop as low as 2000 interrupts per second.  If the
+traffic is mostly transmit or mostly receive, the interrupt rate could
+be as high as 8000.
+
+Setting InterruptThrottleRate to 0 turns off any interrupt moderation
+and may improve small packet latency, but is generally not suitable
+for bulk throughput traffic.
+
+NOTE:
+       InterruptThrottleRate takes precedence over the TxAbsIntDelay and
+       RxAbsIntDelay parameters.  In other words, minimizing the receive
+       and/or transmit absolute delays does not force the controller to
+       generate more interrupts than what the Interrupt Throttle Rate
+       allows.
+
+CAUTION:
+          If you are using the Intel(R) PRO/1000 CT Network Connection
+          (controller 82547), setting InterruptThrottleRate to a value
+          greater than 75,000, may hang (stop transmitting) adapters
+          under certain network conditions.  If this occurs a NETDEV
+          WATCHDOG message is logged in the system event log.  In
+          addition, the controller is automatically reset, restoring
+          the network connection.  To eliminate the potential for the
+          hang, ensure that InterruptThrottleRate is set no greater
+          than 75,000 and is not set to 0.
+
+NOTE:
+       When e1000 is loaded with default settings and multiple adapters
+       are in use simultaneously, the CPU utilization may increase non-
+       linearly.  In order to limit the CPU utilization without impacting
+       the overall throughput, we recommend that you load the driver as
+       follows::
+
+           modprobe e1000 InterruptThrottleRate=3000,3000,3000
+
+       This sets the InterruptThrottleRate to 3000 interrupts/sec for
+       the first, second, and third instances of the driver.  The range
+       of 2000 to 3000 interrupts per second works on a majority of
+       systems and is a good starting point, but the optimal value will
+       be platform-specific.  If CPU utilization is not a concern, use
+       RX_POLLING (NAPI) and default driver settings.
+
+RxDescriptors
+-------------
+
+:Valid Range:
+ - 48-256 for 82542 and 82543-based adapters
+ - 48-4096 for all other supported adapters
+:Default Value: 256
+
+This value specifies the number of receive buffer descriptors allocated
+by the driver.  Increasing this value allows the driver to buffer more
+incoming packets, at the expense of increased system memory utilization.
+
+Each descriptor is 16 bytes.  A receive buffer is also allocated for each
+descriptor and can be either 2048, 4096, 8192, or 16384 bytes, depending
+on the MTU setting. The maximum MTU size is 16110.
+
+NOTE:
+       MTU designates the frame size.  It only needs to be set for Jumbo
+       Frames.  Depending on the available system resources, the request
+       for a higher number of receive descriptors may be denied.  In this
+       case, use a lower number.
+
+RxIntDelay
+----------
+
+:Valid Range:   0-65535 (0=off)
+:Default Value: 0
+
+This value delays the generation of receive interrupts in units of 1.024
+microseconds.  Receive interrupt reduction can improve CPU efficiency if
+properly tuned for specific network traffic.  Increasing this value adds
+extra latency to frame reception and can end up decreasing the throughput
+of TCP traffic.  If the system is reporting dropped receives, this value
+may be set too high, causing the driver to run out of available receive
+descriptors.
+
+CAUTION:
+          When setting RxIntDelay to a value other than 0, adapters may
+          hang (stop transmitting) under certain network conditions.  If
+          this occurs a NETDEV WATCHDOG message is logged in the system
+          event log.  In addition, the controller is automatically reset,
+          restoring the network connection.  To eliminate the potential
+          for the hang ensure that RxIntDelay is set to 0.
+
+RxAbsIntDelay
+-------------
+
+(This parameter is supported only on 82540, 82545 and later adapters.)
+
+:Valid Range:   0-65535 (0=off)
+:Default Value: 128
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+receive interrupt is generated.  Useful only if RxIntDelay is non-zero,
+this value ensures that an interrupt is generated after the initial
+packet is received within the set amount of time.  Proper tuning,
+along with RxIntDelay, may improve traffic throughput in specific network
+conditions.
+
+Speed
+-----
+
+(This parameter is supported only on adapters with copper connections.)
+
+:Valid Settings: 0, 10, 100, 1000
+:Default Value:  0 (auto-negotiate at all supported speeds)
+
+Speed forces the line speed to the specified value in megabits per second
+(Mbps).  If this parameter is not specified or is set to 0 and the link
+partner is set to auto-negotiate, the board will auto-detect the correct
+speed.  Duplex should also be set when Speed is set to either 10 or 100.
+
+TxDescriptors
+-------------
+
+:Valid Range:
+  - 48-256 for 82542 and 82543-based adapters
+  - 48-4096 for all other supported adapters
+:Default Value: 256
+
+This value is the number of transmit descriptors allocated by the driver.
+Increasing this value allows the driver to queue more transmits.  Each
+descriptor is 16 bytes.
+
+NOTE:
+       Depending on the available system resources, the request for a
+       higher number of transmit descriptors may be denied.  In this case,
+       use a lower number.
+
+TxIntDelay
+----------
+
+:Valid Range:   0-65535 (0=off)
+:Default Value: 8
+
+This value delays the generation of transmit interrupts in units of
+1.024 microseconds.  Transmit interrupt reduction can improve CPU
+efficiency if properly tuned for specific network traffic.  If the
+system is reporting dropped transmits, this value may be set too high
+causing the driver to run out of available transmit descriptors.
+
+TxAbsIntDelay
+-------------
+
+(This parameter is supported only on 82540, 82545 and later adapters.)
+
+:Valid Range:   0-65535 (0=off)
+:Default Value: 32
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+transmit interrupt is generated.  Useful only if TxIntDelay is non-zero,
+this value ensures that an interrupt is generated after the initial
+packet is sent on the wire within the set amount of time.  Proper tuning,
+along with TxIntDelay, may improve traffic throughput in specific
+network conditions.
+
+XsumRX
+------
+
+(This parameter is NOT supported on the 82542-based adapter.)
+
+:Valid Range:   0-1
+:Default Value: 1
+
+A value of '1' indicates that the driver should enable IP checksum
+offload for received packets (both UDP and TCP) to the adapter hardware.
+
+Copybreak
+---------
+
+:Valid Range:   0-xxxxxxx (0=off)
+:Default Value: 256
+:Usage: modprobe e1000.ko copybreak=128
+
+Driver copies all packets below or equaling this size to a fresh RX
+buffer before handing it up the stack.
+
+This parameter is different than other parameters, in that it is a
+single (not 1,1,1 etc.) parameter applied to all driver instances and
+it is also available during runtime at
+/sys/module/e1000/parameters/copybreak
+
+SmartPowerDownEnable
+--------------------
+
+:Valid Range: 0-1
+:Default Value:  0 (disabled)
+
+Allows PHY to turn off in lower power states. The user can turn off
+this parameter in supported chipsets.
+
+Speed and Duplex Configuration
+==============================
+
+Three keywords are used to control the speed and duplex configuration.
+These keywords are Speed, Duplex, and AutoNeg.
+
+If the board uses a fiber interface, these keywords are ignored, and the
+fiber interface board only links at 1000 Mbps full-duplex.
+
+For copper-based boards, the keywords interact as follows:
+
+- The default operation is auto-negotiate.  The board advertises all
+  supported speed and duplex combinations, and it links at the highest
+  common speed and duplex mode IF the link partner is set to auto-negotiate.
+
+- If Speed = 1000, limited auto-negotiation is enabled and only 1000 Mbps
+  is advertised (The 1000BaseT spec requires auto-negotiation.)
+
+- If Speed = 10 or 100, then both Speed and Duplex should be set.  Auto-
+  negotiation is disabled, and the AutoNeg parameter is ignored.  Partner
+  SHOULD also be forced.
+
+The AutoNeg parameter is used when more control is required over the
+auto-negotiation process.  It should be used when you wish to control which
+speed and duplex combinations are advertised during the auto-negotiation
+process.
+
+The parameter may be specified as either a decimal or hexadecimal value as
+determined by the bitmap below.
+
+============== ====== ====== ======= ======= ====== ====== ======= ======
+Bit position   7      6      5       4       3      2      1       0
+Decimal Value  128    64     32      16      8      4      2       1
+Hex value      80     40     20      10      8      4      2       1
+Speed (Mbps)   N/A    N/A    1000    N/A     100    100    10      10
+Duplex                       Full            Full   Half   Full    Half
+============== ====== ====== ======= ======= ====== ====== ======= ======
+
+Some examples of using AutoNeg::
+
+  modprobe e1000 AutoNeg=0x01 (Restricts autonegotiation to 10 Half)
+  modprobe e1000 AutoNeg=1 (Same as above)
+  modprobe e1000 AutoNeg=0x02 (Restricts autonegotiation to 10 Full)
+  modprobe e1000 AutoNeg=0x03 (Restricts autonegotiation to 10 Half or 10 Full)
+  modprobe e1000 AutoNeg=0x04 (Restricts autonegotiation to 100 Half)
+  modprobe e1000 AutoNeg=0x05 (Restricts autonegotiation to 10 Half or 100
+  Half)
+  modprobe e1000 AutoNeg=0x020 (Restricts autonegotiation to 1000 Full)
+  modprobe e1000 AutoNeg=32 (Same as above)
+
+Note that when this parameter is used, Speed and Duplex must not be specified.
+
+If the link partner is forced to a specific speed and duplex, then this
+parameter should not be used.  Instead, use the Speed and Duplex parameters
+previously mentioned to force the adapter to the same speed and duplex.
+
+Additional Configurations
+=========================
+
+Jumbo Frames
+------------
+
+  Jumbo Frames support is enabled by changing the MTU to a value larger than
+  the default of 1500.  Use the ifconfig command to increase the MTU size.
+  For example::
+
+       ifconfig eth<x> mtu 9000 up
+
+  This setting is not saved across reboots.  It can be made permanent if
+  you add::
+
+       MTU=9000
+
+  to the file /etc/sysconfig/network-scripts/ifcfg-eth<x>.  This example
+  applies to the Red Hat distributions; other distributions may store this
+  setting in a different location.
+
+Notes:
+  Degradation in throughput performance may be observed in some Jumbo frames
+  environments. If this is observed, increasing the application's socket buffer
+  size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
+  See the specific application manual and /usr/src/linux*/Documentation/
+  networking/ip-sysctl.txt for more details.
+
+  - The maximum MTU setting for Jumbo Frames is 16110.  This value coincides
+    with the maximum Jumbo Frames size of 16128.
+
+  - Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
+    poor performance or loss of link.
+
+  - Adapters based on the Intel(R) 82542 and 82573V/E controller do not
+    support Jumbo Frames. These correspond to the following product names::
+
+     Intel(R) PRO/1000 Gigabit Server Adapter
+     Intel(R) PRO/1000 PM Network Connection
+
+ethtool
+-------
+
+  The driver utilizes the ethtool interface for driver configuration and
+  diagnostics, as well as displaying statistical information.  The ethtool
+  version 1.6 or later is required for this functionality.
+
+  The latest release of ethtool can be found from
+  https://www.kernel.org/pub/software/network/ethtool/
+
+Enabling Wake on LAN (WoL)
+--------------------------
+
+  WoL is configured through the ethtool utility.
+
+  WoL will be enabled on the system during the next shut down or reboot.
+  For this driver version, in order to enable WoL, the e1000 driver must be
+  loaded when shutting down or rebooting the system.

+Identifying Your Adapter
+========================
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+https://www.intel.com/support
+
+
+Command Line Parameters
+=======================
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax::
+
+    modprobe e1000e [<option>=<VAL1>,<VAL2>,...]
+
+There needs to be a <VAL#> for each network port in the system supported by
+this driver. The values will be applied to each instance, in function order.
+For example::
+
+    modprobe e1000e InterruptThrottleRate=16000,16000
+
+In this case, there are two network ports supported by e1000e in the system.
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+NOTE: A descriptor describes a data buffer and attributes related to the data
+buffer. This information is accessed by the hardware.
+
+InterruptThrottleRate
+---------------------
+:Valid Range: 0,1,3,4,100-100000
+:Default Value: 3
+
+Interrupt Throttle Rate controls the number of interrupts each interrupt
+vector can generate per second. Increasing ITR lowers latency at the cost of
+increased CPU utilization, though it may help throughput in some circumstances.
+
+Setting InterruptThrottleRate to a value greater or equal to 100
+will program the adapter to send out a maximum of that many interrupts
+per second, even if more packets have come in. This reduces interrupt
+load on the system and can lower CPU utilization under heavy load,
+but will increase latency as packets are not processed as quickly.
+
+The default behaviour of the driver previously assumed a static
+InterruptThrottleRate value of 8000, providing a good fallback value for
+all traffic types, but lacking in small packet performance and latency.
+The hardware can handle many more small packets per second however, and
+for this reason an adaptive interrupt moderation algorithm was implemented.
+
+The driver has two adaptive modes (setting 1 or 3) in which
+it dynamically adjusts the InterruptThrottleRate value based on the traffic
+that it receives. After determining the type of incoming traffic in the last
+timeframe, it will adjust the InterruptThrottleRate to an appropriate value
+for that traffic.
+
+The algorithm classifies the incoming traffic every interval into
+classes.  Once the class is determined, the InterruptThrottleRate value is
+adjusted to suit that traffic type the best. There are three classes defined:
+"Bulk traffic", for large amounts of packets of normal size; "Low latency",
+for small amounts of traffic and/or a significant percentage of small
+packets; and "Lowest latency", for almost completely small packets or
+minimal traffic.
+
+ - 0: Off
+      Turns off any interrupt moderation and may improve small packet latency.
+      However, this is generally not suitable for bulk throughput traffic due
+      to the increased CPU utilization of the higher interrupt rate.
+ - 1: Dynamic mode
+      This mode attempts to moderate interrupts per vector while maintaining
+      very low latency. This can sometimes cause extra CPU utilization. If
+      planning on deploying e1000e in a latency sensitive environment, this
+      parameter should be considered.
+ - 3: Dynamic Conservative mode (default)
+      In dynamic conservative mode, the InterruptThrottleRate value is set to
+      4000 for traffic that falls in class "Bulk traffic". If traffic falls in
+      the "Low latency" or "Lowest latency" class, the InterruptThrottleRate is
+      increased stepwise to 20000. This default mode is suitable for most
+      applications.
+ - 4: Simplified Balancing mode
+      In simplified mode the interrupt rate is based on the ratio of TX and
+      RX traffic.  If the bytes per second rate is approximately equal, the
+      interrupt rate will drop as low as 2000 interrupts per second.  If the
+      traffic is mostly transmit or mostly receive, the interrupt rate could
+      be as high as 8000.
+ - 100-100000:
+      Setting InterruptThrottleRate to a value greater or equal to 100
+      will program the adapter to send at most that many interrupts per second,
+      even if more packets have come in. This reduces interrupt load on the
+      system and can lower CPU utilization under heavy load, but will increase
+      latency as packets are not processed as quickly.
+
+NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
+RxAbsIntDelay parameters. In other words, minimizing the receive and/or
+transmit absolute delays does not force the controller to generate more
+interrupts than what the Interrupt Throttle Rate allows.
+
+RxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 0
+
+This value delays the generation of receive interrupts in units of 1.024
+microseconds. Receive interrupt reduction can improve CPU efficiency if
+properly tuned for specific network traffic. Increasing this value adds extra
+latency to frame reception and can end up decreasing the throughput of TCP
+traffic. If the system is reporting dropped receives, this value may be set
+too high, causing the driver to run out of available receive descriptors.
+
+CAUTION: When setting RxIntDelay to a value other than 0, adapters may hang
+(stop transmitting) under certain network conditions. If this occurs a NETDEV
+WATCHDOG message is logged in the system event log. In addition, the
+controller is automatically reset, restoring the network connection. To
+eliminate the potential for the hang ensure that RxIntDelay is set to 0.
+
+RxAbsIntDelay
+-------------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 8
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+receive interrupt is generated. This value ensures that an interrupt is
+generated after the initial packet is received within the set amount of time,
+which is useful only if RxIntDelay is non-zero. Proper tuning, along with
+RxIntDelay, may improve traffic throughput in specific network conditions.
+
+TxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 8
+
+This value delays the generation of transmit interrupts in units of 1.024
+microseconds. Transmit interrupt reduction can improve CPU efficiency if
+properly tuned for specific network traffic. If the system is reporting
+dropped transmits, this value may be set too high causing the driver to run
+out of available transmit descriptors.
+
+TxAbsIntDelay
+-------------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 32
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+transmit interrupt is generated. It is useful only if TxIntDelay is non-zero.
+It ensures that an interrupt is generated after the initial Packet is sent on
+the wire within the set amount of time. Proper tuning, along with TxIntDelay,
+may improve traffic throughput in specific network conditions.
+
+copybreak
+---------
+:Valid Range: 0-xxxxxxx (0=off)
+:Default Value: 256
+
+The driver copies all packets below or equaling this size to a fresh receive
+buffer before handing it up the stack.
+This parameter differs from other parameters because it is a single (not 1,1,1
+etc.) parameter applied to all driver instances and it is also available
+during runtime at /sys/module/e1000e/parameters/copybreak.
+
+To use copybreak, type::
+
+    modprobe e1000e.ko copybreak=128
+
+SmartPowerDownEnable
+--------------------
+:Valid Range: 0,1
+:Default Value: 0 (disabled)
+
+Allows the PHY to turn off in lower power states. The user can turn off this
+parameter in supported chipsets.
+
+KumeranLockLoss
+---------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+This workaround skips resetting the PHY at shutdown for the initial silicon
+releases of ICH8 systems.
+
+IntMode
+-------
+:Valid Range: 0-2
+:Default Value: 0
+
+   +-------+----------------+
+   | Value | Interrupt Mode |
+   +=======+================+
+   |   0   |     Legacy     |
+   +-------+----------------+
+   |   1   |       MSI      |
+   +-------+----------------+
+   |   2   |      MSI-X     |
+   +-------+----------------+
+
+IntMode allows load time control over the type of interrupt registered for by
+the driver. MSI-X is required for multiple queue support, and some kernels and
+combinations of kernel .config options will force a lower level of interrupt
+support.
+
+This command will show different values for each type of interrupt::
+
+  cat /proc/interrupts
+
+CrcStripping
+------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+Strip the CRC from received packets before sending up the network stack. If
+you have a machine with a BMC enabled but cannot receive IPMI traffic after
+loading or enabling the driver, try disabling this feature.
+
+WriteProtectNVM
+---------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+If set to 1, configure the hardware to ignore all write/erase cycles to the
+GbE region in the ICHx NVM (in order to prevent accidental corruption of the
+NVM). This feature can be disabled by setting the parameter to 0 during initial
+driver load.
+
+NOTE: The machine must be power cycled (full off/on) when enabling NVM writes
+via setting the parameter to zero. Once the NVM has been locked (via the
+parameter at 1 when the driver loads) it cannot be unlocked except via power
+cycle.
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level of debug messages displayed in the system logs.
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+    ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+    ip link set mtu 9000 dev eth<x>
+    ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 8996. This value coincides
+with the maximum Jumbo Frames size of 9018 bytes.
+
+NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
+poor performance or loss of link.
+
+NOTE: The following adapters limit Jumbo Frames sized packets to a maximum of
+4088 bytes:
+
+  - Intel(R) 82578DM Gigabit Network Connection
+  - Intel(R) 82577LM Gigabit Network Connection
+
+The following adapters do not support Jumbo Frames:
+
+  - Intel(R) PRO/1000 Gigabit Server Adapter
+  - Intel(R) PRO/1000 PM Network Connection
+  - Intel(R) 82562G 10/100 Network Connection
+  - Intel(R) 82562G-2 10/100 Network Connection
+  - Intel(R) 82562GT 10/100 Network Connection
+  - Intel(R) 82562GT-2 10/100 Network Connection
+  - Intel(R) 82562V 10/100 Network Connection
+  - Intel(R) 82562V-2 10/100 Network Connection
+  - Intel(R) 82566DC Gigabit Network Connection
+  - Intel(R) 82566DC-2 Gigabit Network Connection
+  - Intel(R) 82566DM Gigabit Network Connection
+  - Intel(R) 82566MC Gigabit Network Connection
+  - Intel(R) 82566MM Gigabit Network Connection
+  - Intel(R) 82567V-3 Gigabit Network Connection
+  - Intel(R) 82577LC Gigabit Network Connection
+  - Intel(R) 82578DC Gigabit Network Connection
+
+NOTE: Jumbo Frames cannot be configured on an 82579-based Network device if
+MACSec is enabled on the system.
+
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+
+https://www.kernel.org/pub/software/network/ethtool/
+
+NOTE: When validating enable/disable tests on some parts (for example, 82578),
+it is necessary to add a few seconds between tests when working with ethtool.
+
+
+Speed and Duplex Configuration
+------------------------------
+In addressing speed and duplex configuration issues, you need to distinguish
+between copper-based adapters and fiber-based adapters.
+
+In the default mode, an Intel(R) Ethernet Network Adapter using copper
+connections will attempt to auto-negotiate with its link partner to determine
+the best setting. If the adapter cannot establish link with the link partner
+using auto-negotiation, you may need to manually configure the adapter and link
+partner to identical settings to establish link and pass packets. This should
+only be needed when attempting to link with an older switch that does not
+support auto-negotiation or one that has been forced to a specific speed or
+duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
+and higher cannot be forced. Use the autonegotiation advertising setting to
+manually set devices for 1 Gbps and higher.
+
+Speed, duplex, and autonegotiation advertising are configured through the
+ethtool utility.
+
+Caution: Only experienced network administrators should force speed and duplex
+or change autonegotiation advertising manually. The settings at the switch must
+always match the adapter settings. Adapter performance may suffer or your
+adapter may not operate if you configure the adapter differently from your
+switch.
+
+An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
+will not attempt to auto-negotiate with its link partner since those adapters
+operate only in full duplex and only at their native speed.
+
+
+Enabling Wake on LAN (WoL)
+--------------------------
+WoL is configured through the ethtool utility.
+
+WoL will be enabled on the system during the next shut down or reboot. For
+this driver version, in order to enable WoL, the e1000e driver must be loaded
+prior to shutting down or suspending the system.
+
+NOTE: Wake on LAN is only supported on port A for the following devices:
+- Intel(R) PRO/1000 PT Dual Port Network Connection
+- Intel(R) PRO/1000 PT Dual Port Server Connection
+- Intel(R) PRO/1000 PT Dual Port Server Adapter
+- Intel(R) PRO/1000 PF Dual Port Server Adapter
+- Intel(R) PRO/1000 PT Quad Port Server Adapter
+- Intel(R) Gigabit PT Quad Port Server ExpressModule

+Identifying Your Adapter
+========================
+The driver in this release is compatible with devices based on the Intel(R)
+Ethernet Multi-host Controller.
+
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+
+Flow Control
+------------
+The Intel(R) Ethernet Switch Host Interface Driver does not support Flow
+Control. It will not send pause frames. This may result in dropped frames.
+
+
+Virtual Functions (VFs)
+-----------------------
+Use sysfs to enable VFs.
+Valid Range: 0-64
+
+For example::
+
+    echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs //enable VFs
+    echo 0 > /sys/class/net/$dev/device/sriov_numvfs //disable VFs
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When SR-IOV mode is enabled, hardware VLAN filtering and VLAN tag
+stripping/insertion will remain enabled. Please remove the old VLAN filter
+before the new VLAN filter is added. For example::
+
+    ip link set eth0 vf 0 vlan 100	// set vlan 100 for VF 0
+    ip link set eth0 vf 0 vlan 0	// Delete vlan 100
+    ip link set eth0 vf 0 vlan 200	// set a new vlan 200 for VF 0
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+    ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+    ip link set mtu 9000 dev eth<x>
+    ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 15342. This value coincides
+with the maximum Jumbo Frames size of 15364 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+
+Generic Receive Offload, aka GRO
+--------------------------------
+The driver supports the in-kernel software implementation of GRO. GRO has
+shown that by coalescing Rx traffic into larger chunks of data, CPU
+utilization can be significantly reduced when under large Rx load. GRO is an
+evolution of the previously-used LRO interface. GRO is able to coalesce
+other protocols besides TCP. It's also safe to use with configurations that
+are problematic for LRO, namely bridging and iSCSI.
+
+
+
+Supported ethtool Commands and Options for Filtering
+----------------------------------------------------
+-n --show-nfc
+  Retrieves the receive network flow classification configurations.
+
+rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6

+
+- udp4: UDP over IPv4
+- udp6: UDP over IPv6
+- f Hash on bytes 0 and 1 of the Layer 4 header of the rx packet.
+- n Hash on bytes 2 and 3 of the Layer 4 header of the rx packet.

+
+
+Identifying Your Adapter
+========================
+The driver is compatible with devices based on the following:
+
+ * Intel(R) Ethernet Controller X710
+ * Intel(R) Ethernet Controller XL710
+ * Intel(R) Ethernet Network Connection X722
+ * Intel(R) Ethernet Controller XXV710
+
+For the best performance, make sure the latest NVM/FW is installed on your

+----------------------
+For information about supported media, refer to this document:
+https://www.intel.com/content/dam/www/public/us/en/documents/release-notes/xl710-ethernet-controller-feature-matrix.pdf
+
+NOTE: Some adapters based on the Intel(R) Ethernet Controller 700 Series only
+support Intel Ethernet Optics modules. On these adapters, other modules are not
+supported and will not function.  In all cases Intel recommends using Intel
+Ethernet Optics; other modules may function but are not validated by Intel.
+Contact Intel for supported media types.
+
+NOTE: For connections based on Intel(R) Ethernet Controller 700 Series, support
+is dependent on your system board. Please see your vendor for details.
+
+NOTE: In systems that do not have adequate airflow to cool the adapter and
+optical modules, you must use high temperature optical modules.
+
+Virtual Functions (VFs)
+-----------------------
+Use sysfs to enable VFs. For example::
+
+  #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs #enable VFs
+  #echo 0 > /sys/class/net/$dev/device/sriov_numvfs #disable VFs
+
+For example, the following instructions will configure PF eth0 and the first VF
+on VLAN 10::
+
+  $ ip link set dev eth0 vf 0 vlan 10
+
+VLAN Tag Packet Steering
+------------------------
+Allows you to send all packets with a specific VLAN tag to a particular SR-IOV
+virtual function (VF). Further, this feature allows you to designate a
+particular VF as trusted, and allows that trusted VF to request selective
+promiscuous mode on the Physical Function (PF).
+
+To set a VF as trusted or untrusted, enter the following command in the
+Hypervisor::
+
+  # ip link set dev eth0 vf 1 trust [on|off]
+
+Once the VF is designated as trusted, use the following commands in the VM to
+set the VF to promiscuous mode.
+
+::
+
+  For promiscuous all:
+  #ip link set eth2 promisc on
+  Where eth2 is a VF interface in the VM
+
+  For promiscuous Multicast:
+  #ip link set eth2 allmulticast on
+  Where eth2 is a VF interface in the VM
+
+NOTE: By default, the ethtool priv-flag vf-true-promisc-support is set to
+"off",meaning that promiscuous mode for the VF will be limited. To set the
+promiscuous mode for the VF to true promiscuous and allow the VF to see all
+ingress traffic, use the following command::
+
+  #ethtool -set-priv-flags p261p1 vf-true-promisc-support on
+
+The vf-true-promisc-support priv-flag does not enable promiscuous mode; rather,
+it designates which type of promiscuous mode (limited or true) you will get
+when you enable promiscuous mode using the ip link commands above. Note that
+this is a global setting that affects the entire device. However,the
+vf-true-promisc-support priv-flag is only exposed to the first PF of the
+device. The PF remains in limited promiscuous mode (unless it is in MFP mode)
+regardless of the vf-true-promisc-support setting.
+
+Now add a VLAN interface on the VF interface::
+
+  #ip link add link eth2 name eth2.100 type vlan id 100
+
+Note that the order in which you set the VF to promiscuous mode and add the
+VLAN interface does not matter (you can do either first). The end result in
+this example is that the VF will get all traffic that is tagged with VLAN 100.
+
+Intel(R) Ethernet Flow Director
+-------------------------------
+The Intel Ethernet Flow Director performs the following tasks:
+
+- Directs receive packets according to their flows to different queues.
+- Enables tight control on routing a flow in the platform.
+- Matches flows and CPU cores for flow affinity.
+- Supports multiple parameters for flexible flow classification and load
+  balancing (in SFP mode only).
+
+NOTE: The Linux i40e driver supports the following flow types: IPv4, TCPv4, and
+UDPv4. For a given flow type, it supports valid combinations of IP addresses
+(source or destination) and UDP/TCP ports (source and destination). For
+example, you can supply only a source IP address, a source IP address and a
+destination port, or any combination of one or more of these four parameters.
+
+NOTE: The Linux i40e driver allows you to filter traffic based on a
+user-defined flexible two-byte pattern and offset by using the ethtool user-def
+and mask fields. Only L3 and L4 flow types are supported for user-defined
+flexible filters. For a given flow type, you must clear all Intel Ethernet Flow
+Director filters before changing the input set (for that flow type).
+
+To enable or disable the Intel Ethernet Flow Director::
+
+  # ethtool -K ethX ntuple <on|off>
+
+When disabling ntuple filters, all the user programmed filters are flushed from
+the driver cache and hardware. All needed filters must be re-added when ntuple
+is re-enabled.
+
+To add a filter that directs packet to queue 2, use -U or -N switch::
+
+  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+  192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
+
+To set a filter using only the source and destination IP address::
+
+  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+  192.168.10.2 action 2 [loc 1]
+
+To see the list of filters currently present::
+
+  # ethtool <-u|-n> ethX
+
+Application Targeted Routing (ATR) Perfect Filters
+--------------------------------------------------
+ATR is enabled by default when the kernel is in multiple transmit queue mode.
+An ATR Intel Ethernet Flow Director filter rule is added when a TCP-IP flow
+starts and is deleted when the flow ends. When a TCP-IP Intel Ethernet Flow
+Director rule is added from ethtool (Sideband filter), ATR is turned off by the
+driver. To re-enable ATR, the sideband can be disabled with the ethtool -K
+option. For example::
+
+  ethtool –K [adapter] ntuple [off|on]
+
+If sideband is re-enabled after ATR is re-enabled, ATR remains enabled until a
+TCP-IP flow is added. When all TCP-IP sideband rules are deleted, ATR is
+automatically re-enabled.
+
+Packets that match the ATR rules are counted in fdir_atr_match stats in
+ethtool, which also can be used to verify whether ATR rules still exist.
+
+Sideband Perfect Filters
+------------------------
+Sideband Perfect Filters are used to direct traffic that matches specified
+characteristics. They are enabled through ethtool's ntuple interface. To add a
+new filter use the following command::
+
+  ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
+  dst-port <port> action <queue>
+
+Where:
+  <device> - the ethernet device to program
+  <type> - can be ip4, tcp4, udp4, or sctp4
+  <ip> - the ip address to match on
+  <port> - the port number to match on
+  <queue> - the queue to direct traffic towards (-1 discards matching traffic)
+
+Use the following command to display all of the active filters::
+
+  ethtool -u <device>
+
+Use the following command to delete a filter::
+
+  ethtool -U <device> delete <N>
+
+Where <N> is the filter id displayed when printing all the active filters, and
+may also have been specified using "loc <N>" when adding the filter.
+
+The following example matches TCP traffic sent from 192.168.0.1, port 5300,
+directed to 192.168.0.5, port 80, and sends it to queue 7::
+
+  ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
+  src-port 5300 dst-port 80 action 7
+
+For each flow-type, the programmed filters must all have the same matching
+input set. For example, issuing the following two commands is acceptable::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
+
+Issuing the next two commands, however, is not acceptable, since the first
+specifies src-ip and the second specifies dst-ip::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
+
+The second command will fail with an error. You may program multiple filters
+with the same fields, using different values, but, on one device, you may not
+program two tcp4 filters with different matching fields.
+
+Matching on a sub-portion of a field is not supported by the i40e driver, thus
+partial mask fields are not supported.
+
+The driver also supports matching user-defined data within the packet payload.
+This flexible data is specified using the "user-def" field of the ethtool
+command in the following way:
+
++----------------------------+--------------------------+
+| 31    28    24    20    16 | 15    12    8    4    0  |
++----------------------------+--------------------------+
+| offset into packet payload | 2 bytes of flexible data |
++----------------------------+--------------------------+
+
+For example,
+
+::
+
+  ... user-def 0x4FFFF ...
+
+tells the filter to look 4 bytes into the payload and match that value against
+0xFFFF. The offset is based on the beginning of the payload, and not the
+beginning of the packet. Thus
+
+::
+
+  flow-type tcp4 ... user-def 0x8BEAF ...
+
+would match TCP/IPv4 packets which have the value 0xBEAF 8 bytes into the
+TCP/IPv4 payload.
+
+Note that ICMP headers are parsed as 4 bytes of header and 4 bytes of payload.
+Thus to match the first byte of the payload, you must actually add 4 bytes to
+the offset. Also note that ip4 filters match both ICMP frames as well as raw
+(unknown) ip4 frames, where the payload will be the L3 payload of the IP4 frame.
+
+The maximum offset is 64. The hardware will only read up to 64 bytes of data
+from the payload. The offset must be even because the flexible data is 2 bytes
+long and must be aligned to byte 0 of the packet payload.
+
+The user-defined flexible offset is also considered part of the input set and
+cannot be programmed separately for multiple filters of the same type. However,
+the flexible data is not part of the input set and multiple filters may use the
+same offset but match against different data.
+
+To create filters that direct traffic to a specific Virtual Function, use the
+"action" parameter. Specify the action as a 64 bit value, where the lower 32
+bits represents the queue number, while the next 8 bits represent which VF.
+Note that 0 is the PF, so the VF identifier is offset by 1. For example::
+
+  ... action 0x800000002 ...
+
+specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
+that VF.
+
+Note that these filters will not break internal routing rules, and will not
+route traffic that otherwise would not have been sent to the specified Virtual
+Function.
+
+Setting the link-down-on-close Private Flag
+-------------------------------------------
+When the link-down-on-close private flag is set to "on", the port's link will
+go down when the interface is brought down using the ifconfig ethX down command.
+
+Use ethtool to view and set link-down-on-close, as follows::
+
+  ethtool --show-priv-flags ethX
+  ethtool --set-priv-flags ethX link-down-on-close [on|off]
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+  dmesg -n 8
+
+NOTE: This setting is not saved across reboots.
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+  ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+  ip link set mtu 9000 dev eth<x>
+  ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file::
+
+  /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
+  /etc/sysconfig/network/<config_file> // for SLES
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9702. This value coincides
+with the maximum Jumbo Frames size of 9728 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+Supported ethtool Commands and Options for Filtering
+----------------------------------------------------
+-n --show-nfc
+  Retrieves the receive network flow classification configurations.
+
+rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6
+  Retrieves the hash options for the specified network traffic type.
+
+-N --config-nfc
+  Configures the receive network flow classification.
+
+rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 m|v|t|s|d|f|n|r...
+  Configures the hash options for the specified network traffic type.
+
+udp4 UDP over IPv4
+udp6 UDP over IPv6
+
+f Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
+n Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
+
+Speed and Duplex Configuration
+------------------------------
+In addressing speed and duplex configuration issues, you need to distinguish
+between copper-based adapters and fiber-based adapters.
+
+In the default mode, an Intel(R) Ethernet Network Adapter using copper
+connections will attempt to auto-negotiate with its link partner to determine
+the best setting. If the adapter cannot establish link with the link partner
+using auto-negotiation, you may need to manually configure the adapter and link
+partner to identical settings to establish link and pass packets. This should
+only be needed when attempting to link with an older switch that does not
+support auto-negotiation or one that has been forced to a specific speed or
+duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
+and higher cannot be forced. Use the autonegotiation advertising setting to
+manually set devices for 1 Gbps and higher.
+
+NOTE: You cannot set the speed for devices based on the Intel(R) Ethernet
+Network Adapter XXV710 based devices.
+
+Speed, duplex, and autonegotiation advertising are configured through the
+ethtool utility.
+
+Caution: Only experienced network administrators should force speed and duplex
+or change autonegotiation advertising manually. The settings at the switch must
+always match the adapter settings. Adapter performance may suffer or your
+adapter may not operate if you configure the adapter differently from your
+switch.
+
+An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
+will not attempt to auto-negotiate with its link partner since those adapters
+operate only in full duplex and only at their native speed.
+
+NAPI
+----
+NAPI (Rx polling mode) is supported in the i40e driver.
+For more information on NAPI, see
+https://wiki.linuxfoundation.org/networking/napi
+
+Flow Control
+------------
+Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
+receiving and transmitting pause frames for i40e. When transmit is enabled,
+pause frames are generated when the receive packet buffer crosses a predefined
+threshold. When receive is enabled, the transmit unit will halt for the time
+delay specified when a pause frame is received.
+
+NOTE: You must have a flow control capable link partner.
+
+Flow Control is on by default.
+
+Use ethtool to change the flow control settings.
+
+To enable or disable Rx or Tx Flow Control::
+
+  ethtool -A eth? rx <on|off> tx <on|off>
+
+Note: This command only enables or disables Flow Control if auto-negotiation is
+disabled. If auto-negotiation is enabled, this command changes the parameters
+used for auto-negotiation with the link partner.
+
+To enable or disable auto-negotiation::
+
+  ethtool -s eth? autoneg <on|off>
+
+Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
+on your device, you may not be able to change the auto-negotiation setting.
+
+RSS Hash Flow
+-------------
+Allows you to set the hash bytes per flow type and any combination of one or
+more options for Receive Side Scaling (RSS) hash byte configuration.
+
+::
+
+  # ethtool -N <dev> rx-flow-hash <type> <option>
+
+Where <type> is:
+  tcp4	signifying TCP over IPv4
+  udp4	signifying UDP over IPv4
+  tcp6	signifying TCP over IPv6
+  udp6	signifying UDP over IPv6
+And <option> is one or more of:
+  s	Hash on the IP source address of the Rx packet.
+  d	Hash on the IP destination address of the Rx packet.
+  f	Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
+  n	Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+NOTE: This feature can be disabled for a specific Virtual Function (VF)::
+
+  ip link set <pf dev> vf <vf id> spoofchk {off|on}
+
+IEEE 1588 Precision Time Protocol (PTP) Hardware Clock (PHC)
+------------------------------------------------------------
+Precision Time Protocol (PTP) is used to synchronize clocks in a computer
+network. PTP support varies among Intel devices that support this driver. Use
+"ethtool -T <netdev name>" to get a definitive list of PTP capabilities
+supported by the device.
+
+IEEE 802.1ad (QinQ) Support
+---------------------------
+The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
+IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
+"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
+allow L2 tunneling and the ability to segregate traffic within a particular
+VLAN ID, among other uses.
+
+The following are examples of how to configure 802.1ad (QinQ)::
+
+  ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
+  ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
+
+Where "24" and "371" are example VLAN IDs.
+
+NOTES:
+  Receive checksum offloads, cloud filters, and VLAN acceleration are not
+  supported for 802.1ad (QinQ) packets.
+
+VXLAN and GENEVE Overlay HW Offloading
+--------------------------------------
+Virtual Extensible LAN (VXLAN) allows you to extend an L2 network over an L3
+network, which may be useful in a virtualized or cloud environment. Some
+Intel(R) Ethernet Network devices perform VXLAN processing, offloading it from
+the operating system. This reduces CPU utilization.
+
+VXLAN offloading is controlled by the Tx and Rx checksum offload options
+provided by ethtool. That is, if Tx checksum offload is enabled, and the
+adapter has the capability, VXLAN offloading is also enabled.
+
+Support for VXLAN and GENEVE HW offloading is dependent on kernel support of
+the HW offloading features.
+
+Multiple Functions per Port
+---------------------------
+Some adapters based on the Intel Ethernet Controller X710/XL710 support
+multiple functions on a single physical port. Configure these functions through
+the System Setup/BIOS.
+
+Minimum TX Bandwidth is the guaranteed minimum data transmission bandwidth, as
+a percentage of the full physical port link speed, that the partition will
+receive. The bandwidth the partition is awarded will never fall below the level
+you specify.
+
+The range for the minimum bandwidth values is:
+1 to ((100 minus # of partitions on the physical port) plus 1)
+For example, if a physical port has 4 partitions, the range would be:
+1 to ((100 - 4) + 1 = 97)
+
+The Maximum Bandwidth percentage represents the maximum transmit bandwidth
+allocated to the partition as a percentage of the full physical port link
+speed. The accepted range of values is 1-100. The value is used as a limiter,
+should you chose that any one particular function not be able to consume 100%
+of a port's bandwidth (should it be available). The sum of all the values for
+Maximum Bandwidth is not restricted, because no more than 100% of a port's
+bandwidth can ever be used.
+
+NOTE: X710/XXV710 devices fail to enable Max VFs (64) when Multiple Functions
+per Port (MFP) and SR-IOV are enabled. An error from i40e is logged that says
+"add vsi failed for VF N, aq_err 16". To workaround the issue, enable less than
+64 virtual functions (VFs).
+
+Data Center Bridging (DCB)
+--------------------------
+DCB is a configuration Quality of Service implementation in hardware. It uses
+the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
+different priorities that traffic can be filtered into. It also enables
+priority flow control (802.1Qbb) which can limit or eliminate the number of
+dropped packets during network stress. Bandwidth can be allocated to each of
+these priorities, which is enforced at the hardware level (802.1Qaz).
+
+Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
+802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
+and can accept settings from a DCBX capable peer. Software configuration of
+DCBX parameters via dcbtool/lldptool are not supported.
+
+NOTE: Firmware LLDP can be disabled by setting the private flag disable-fw-lldp.
+
+The i40e driver implements the DCB netlink interface layer to allow user-space
+to communicate with the driver and query DCB configuration for the port.
+
+NOTE:
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.
+
+Interrupt Rate Limiting
+-----------------------
+:Valid Range: 0-235 (0=no limit)
+
+The Intel(R) Ethernet Controller XL710 family supports an interrupt rate
+limiting mechanism. The user can control, via ethtool, the number of
+microseconds between interrupts.
+
+Syntax::
+
+  # ethtool -C ethX rx-usecs-high N
+
+The range of 0-235 microseconds provides an effective range of 4,310 to 250,000
+interrupts per second. The value of rx-usecs-high can be set independently of
+rx-usecs and tx-usecs in the same ethtool command, and is also independent of
+the adaptive interrupt moderation algorithm. The underlying hardware supports
+granularity in 4-microsecond intervals, so adjacent values may result in the
+same interrupt rate.
+
+One possible use case is the following::
+
+  # ethtool -C ethX adaptive-rx off adaptive-tx off rx-usecs-high 20 rx-usecs \
+    5 tx-usecs 5
+
+The above command would disable adaptive interrupt moderation, and allow a
+maximum of 5 microseconds before indicating a receive or transmit was complete.
+However, instead of resulting in as many as 200,000 interrupts per second, it
+limits total interrupts per second to 50,000 via the rx-usecs-high parameter.
+
+Performance Optimization
+========================
+Driver defaults are meant to fit a wide variety of workloads, but if further
+optimization is required we recommend experimenting with the following settings.
+
+NOTE: For better performance when processing small (64B) frame sizes, try
+enabling Hyper threading in the BIOS in order to increase the number of logical
+cores in the system and subsequently increase the number of queues available to
+the adapter.
+
+Virtualized Environments
+------------------------
+1. Disable XPS on both ends by using the included virt_perf_default script
+or by running the following command as root::
+
+  for file in `ls /sys/class/net/<ethX>/queues/tx-*/xps_cpus`;
+  do echo 0 > $file; done
+
+2. Using the appropriate mechanism (vcpupin) in the vm, pin the cpu's to
+individual lcpu's, making sure to use a set of cpu's included in the
+device's local_cpulist: /sys/class/net/<ethX>/device/local_cpulist.
+
+3. Configure as many Rx/Tx queues in the VM as available. Do not rely on
+the default setting of 1.
+
+
+Non-virtualized Environments
+----------------------------
+Pin the adapter's IRQs to specific cores by disabling the irqbalance service
+and using the included set_irq_affinity script. Please see the script's help
+text for further options.
+
+- The following settings will distribute the IRQs across all the cores evenly::
+
+  # scripts/set_irq_affinity -x all <interface1> , [ <interface2>, ... ]
+
+- The following settings will distribute the IRQs across all the cores that are
+  local to the adapter (same NUMA node)::
+
+  # scripts/set_irq_affinity -x local <interface1> ,[ <interface2>, ... ]
+
+For very CPU intensive workloads, we recommend pinning the IRQs to all cores.
+
+For IP Forwarding: Disable Adaptive ITR and lower Rx and Tx interrupts per
+queue using ethtool.
+
+- Setting rx-usecs and tx-usecs to 125 will limit interrupts to about 8000
+  interrupts per second per queue.
+
+::
+
+  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 125 \
+    tx-usecs 125
+
+For lower CPU utilization: Disable Adaptive ITR and lower Rx and Tx interrupts
+per queue using ethtool.
+
+- Setting rx-usecs and tx-usecs to 250 will limit interrupts to about 4000
+  interrupts per second per queue.
+
+::
+
+  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 250 \
+    tx-usecs 250
+
+For lower latency: Disable Adaptive ITR and ITR by setting Rx and Tx to 0 using
+ethtool.
+
+::
+
+  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 0 \
+    tx-usecs 0
+
+Application Device Queues (ADq)
+-------------------------------
+Application Device Queues (ADq) allows you to dedicate one or more queues to a
+specific application. This can reduce latency for the specified application,
+and allow Tx traffic to be rate limited per application. Follow the steps below
+to set ADq.
+
+1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
+The shaper bw_rlimit parameter is optional.
+
+Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
+to 1Gbit for tc0 and 3Gbit for tc1.
+
+::
+
+  # tc qdisc add dev <interface> root mqprio num_tc 2 map 0 0 0 0 1 1 1 1
+  queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
+  max_rate 1Gbit 3Gbit
+
+map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
+sets priorities 0-3 to use tc0 and 4-7 to use tc1)
+
+queues: for each tc, <num queues>@<offset> (e.g. queues 16@0 16@16 assigns
+16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
+number of queues for all tcs is 64 or number of cores, whichever is lower.)
+
+hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
+offload mode in mqprio that makes full use of the mqprio options, the
+TCs, the queue configurations, and the QoS parameters.
+
+shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
+Totals must be equal or less than port speed.
+
+For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
+monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
+
+2. Enable HW TC offload on interface::
+
+    # ethtool -K <interface> hw-tc-offload on
+
+3. Apply TCs to ingress (RX) flow of interface::
+
+    # tc qdisc add dev <interface> ingress
+
+NOTES:
+ - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory.
+ - ADq is not compatible with cloud filters.
+ - Setting up channels via ethtool (ethtool -L) is not supported when the
+   TCs are configured using mqprio.
+ - You must have iproute2 latest version
+ - NVM version 6.01 or later is required.
+ - ADq cannot be enabled when any the following features are enabled: Data
+   Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband
+   Filters.
+ - If another driver (for example, DPDK) has set cloud filters, you cannot
+   enable ADq.
+ - Tunnel filters are not supported in ADq. If encapsulated packets do
+   arrive in non-tunnel mode, filtering will be done on the inner headers.
+   For example, for VXLAN traffic in non-tunnel mode, PCTYPE is identified
+   as a VXLAN encapsulated packet, outer headers are ignored. Therefore,
+   inner headers are matched.
+ - If a TC filter on a PF matches traffic over a VF (on the PF), that
+   traffic will be routed to the appropriate queue of the PF, and will
+   not be passed on the VF. Such traffic will end up getting dropped higher
+   up in the TCP/IP stack as it does not match PF address data.
+ - If traffic matches multiple TC filters that point to different TCs,
+   that traffic will be duplicated and sent to all matching TC queues.
+   The hardware switch mirrors the packet to a VSI list when multiple
+   filters are matched.
+
+
+Known Issues/Troubleshooting
+============================
+
+NOTE: 1 Gb devices based on the Intel(R) Ethernet Network Connection X722 do
+not support the following features:
+
+  * Data Center Bridging (DCB)
+  * QOS
+  * VMQ
+  * SR-IOV
+  * Task Encapsulation offload (VXLAN, NVGRE)
+  * Energy Efficient Ethernet (EEE)
+  * Auto-media detect
+
+Unexpected Issues when the device driver and DPDK share a device
+----------------------------------------------------------------
+Unexpected issues may result when an i40e device is in multi driver mode and
+the kernel driver and DPDK driver are sharing the device. This is because
+access to the global NIC resources is not synchronized between multiple
+drivers. Any change to the global NIC configuration (writing to a global
+register, setting global configuration by AQ, or changing switch modes) will
+affect all ports and drivers on the device. Loading DPDK with the
+"multi-driver" module parameter may mitigate some of the issues.
+
+TC0 must be enabled when setting up DCB on a switch
+---------------------------------------------------
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.

+Overview
+========
+
+This file describes the iavf Linux Base Driver. This driver was formerly
+called i40evf.
+
+The iavf driver supports the below mentioned virtual function devices and
+can only be activated on kernels running the i40e or newer Physical Function
+(PF) driver compiled with CONFIG_PCI_IOV.  The iavf driver requires
+CONFIG_PCI_MSI to be enabled.
+
+The guest OS loading the iavf driver must support MSI-X interrupts.
+
+Identifying Your Adapter
+========================
+
+The driver in this kernel is compatible with devices based on the following:
+ * Intel(R) XL710 X710 Virtual Function
+ * Intel(R) X722 Virtual Function
+ * Intel(R) XXV710 Virtual Function
+ * Intel(R) Ethernet Adaptive Virtual Function
+
+For the best performance, make sure the latest NVM/FW is installed on your
+device.

+If you have applications that require Virtual Functions (VFs) to receive
+packets with VLAN tags, you can disable VLAN tag stripping for the VF. The
+Physical Function (PF) processes requests issued from the VF to enable or
+disable VLAN tag stripping. Note that if the PF has assigned a VLAN to a VF,
+then requests from that VF to set VLAN tag stripping will be ignored.
+
+To enable/disable VLAN tag stripping for a VF, issue the following command
+from inside the VM in which you are running the VF::
+
+    # ethtool -K <if_name> rxvlan on/off
+
+or alternatively::
+
+    # ethtool --offload <if_name> rxvlan on/off
+
+Adaptive Virtual Function
+-------------------------
+Adaptive Virtual Function (AVF) allows the virtual function driver, or VF, to
+adapt to changing feature sets of the physical function driver (PF) with which
+it is associated. This allows system administrators to update a PF without
+having to update all the VFs associated with it. All AVFs have a single common
+device ID and branding string.
+
+AVFs have a minimum set of features known as "base mode," but may provide
+additional features depending on what features are available in the PF with
+which the AVF is associated. The following are base mode features:
+
+- 4 Queue Pairs (QP) and associated Configuration Status Registers (CSRs)
+  for Tx/Rx
+- i40e descriptors and ring format
+- Descriptor write-back completion
+- 1 control queue, with i40e descriptors, CSRs and ring format
+- 5 MSI-X interrupt vectors and corresponding i40e CSRs
+- 1 Interrupt Throttle Rate (ITR) index
+- 1 Virtual Station Interface (VSI) per VF
+- 1 Traffic Class (TC), TC0
+- Receive Side Scaling (RSS) with 64 entry indirection table and key,
+  configured through the PF
+- 1 unicast MAC address reserved per VF
+- 16 MAC address filters for each VF
+- Stateless offloads - non-tunneled checksums
+- AVF device ID
+- HW mailbox is used for VF to PF communications (including on Windows)
+
+IEEE 802.1ad (QinQ) Support
+---------------------------
+The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
+IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
+"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
+allow L2 tunneling and the ability to segregate traffic within a particular
+VLAN ID, among other uses.
+
+The following are examples of how to configure 802.1ad (QinQ)::
+
+    # ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
+    # ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
+
+Where "24" and "371" are example VLAN IDs.
+
+NOTES:
+  Receive checksum offloads, cloud filters, and VLAN acceleration are not
+  supported for 802.1ad (QinQ) packets.
+
+Application Device Queues (ADq)
+-------------------------------
+Application Device Queues (ADq) allows you to dedicate one or more queues to a
+specific application. This can reduce latency for the specified application,
+and allow Tx traffic to be rate limited per application. Follow the steps below
+to set ADq.
+
+Requirements:
+
+- The sch_mqprio, act_mirred and cls_flower modules must be loaded
+- The latest version of iproute2
+- If another driver (for example, DPDK) has set cloud filters, you cannot
+  enable ADQ
+- Depending on the underlying PF device, ADQ cannot be enabled when the
+  following features are enabled:
+
+  + Data Center Bridging (DCB)
+  + Multiple Functions per Port (MFP)
+  + Sideband Filters
+
+1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
+The shaper bw_rlimit parameter is optional.
+
+Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
+to 1Gbit for tc0 and 3Gbit for tc1.
+
+::
+
+    tc qdisc add dev <interface> root mqprio num_tc 2 map 0 0 0 0 1 1 1 1
+    queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
+    max_rate 1Gbit 3Gbit
+
+map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
+sets priorities 0-3 to use tc0 and 4-7 to use tc1)
+
+queues: for each tc, <num queues>@<offset> (e.g. queues 16@0 16@16 assigns
+16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
+number of queues for all tcs is 64 or number of cores, whichever is lower.)
+
+hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
+offload mode in mqprio that makes full use of the mqprio options, the
+TCs, the queue configurations, and the QoS parameters.
+
+shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
+Totals must be equal or less than port speed.
+
+For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
+monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
+
+NOTE:
+  Setting up channels via ethtool (ethtool -L) is not supported when the
+  TCs are configured using mqprio.
+
+2. Enable HW TC offload on interface::
+
+    # ethtool -K <interface> hw-tc-offload on
+
+3. Apply TCs to ingress (RX) flow of interface::
+
+    # tc qdisc add dev <interface> ingress
+
+NOTES:
+ - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory
+ - ADq is not compatible with cloud filters
+ - Setting up channels via ethtool (ethtool -L) is not supported when the TCs
+   are configured using mqprio
+ - You must have iproute2 latest version
+ - NVM version 6.01 or later is required
+ - ADq cannot be enabled when any the following features are enabled: Data
+   Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband Filters
+ - If another driver (for example, DPDK) has set cloud filters, you cannot
+   enable ADq
+ - Tunnel filters are not supported in ADq. If encapsulated packets do arrive
+   in non-tunnel mode, filtering will be done on the inner headers.  For example,
+   for VXLAN traffic in non-tunnel mode, PCTYPE is identified as a VXLAN
+   encapsulated packet, outer headers are ignored. Therefore, inner headers are
+   matched.
+ - If a TC filter on a PF matches traffic over a VF (on the PF), that traffic
+   will be routed to the appropriate queue of the PF, and will not be passed on
+   the VF. Such traffic will end up getting dropped higher up in the TCP/IP
+   stack as it does not match PF address data.
+ - If traffic matches multiple TC filters that point to different TCs, that
+   traffic will be duplicated and sent to all matching TC queues.  The hardware
+   switch mirrors the packet to a VSI list when multiple filters are matched.
+
+
+Known Issues/Troubleshooting
+============================
+
+Bonding fails with VFs bound to an Intel(R) Ethernet Controller 700 series device
+---------------------------------------------------------------------------------
+If you bind Virtual Functions (VFs) to an Intel(R) Ethernet Controller 700
+series based device, the VF slaves may fail when they become the active slave.
+If the MAC address of the VF is set by the PF (Physical Function) of the
+device, when you add a slave, or change the active-backup slave, Linux bonding
+tries to sync the backup slave's MAC address to the same MAC address as the
+active slave. Linux bonding will fail at this point. This issue will not occur
+if the VF's MAC address is not set by the PF.
+
+Traffic Is Not Being Passed Between VM and Client
+-------------------------------------------------
+You may not be able to pass traffic between a client system and a
+Virtual Machine (VM) running on a separate host if the Virtual Function
+(VF, or Virtual NIC) is not in trusted mode and spoof checking is enabled
+on the VF. Note that this situation can occur in any combination of client,
+host, and guest operating system. For information on how to set the VF to
+trusted mode, refer to the section "VLAN Tag Packet Steering" in this
+readme document. For information on setting spoof checking, refer to the
+section "MAC and VLAN anti-spoofing feature" in this readme document.
+
+Do not unload port driver if VF with active VM is bound to it
+-------------------------------------------------------------
+Do not unload a port's driver if a Virtual Function (VF) with an active Virtual
+Machine (VM) is bound to it. Doing so will cause the port to appear to hang.
+Once the VM shuts down, or otherwise releases the VF, the command will complete.
+
+Using four traffic classes fails
+--------------------------------
+Do not try to reserve more than three traffic classes in the iavf driver. Doing
+so will fail to set any traffic classes and will cause the driver to write
+errors to stdout. Use a maximum of three queues to avoid this issue.
+
+Multiple log error messages on iavf driver removal
+--------------------------------------------------
+If you have several VFs and you remove the iavf driver, several instances of
+the following log errors are written to the log::
+
+    Unable to send opcode 2 to PF, err I40E_ERR_QUEUE_EMPTY, aq_err ok
+    Unable to send the message to VF 2 aq_err 12
+    ARQ Overflow Error detected
+
+Virtual machine does not get link
+---------------------------------
+If the virtual machine has more than one virtual port assigned to it, and those
+virtual ports are bound to different physical ports, you may not get link on
+all of the virtual ports. The following command may work around the issue::
+
+    # ethtool -r <PF>
+
+Where <PF> is the PF interface in the host, for example: p5p1. You may need to
+run the command more than once to get link on all virtual ports.
+
+MAC address of Virtual Function changes unexpectedly
+----------------------------------------------------
+If a Virtual Function's MAC address is not assigned in the host, then the VF
+(virtual function) driver will use a random MAC address. This random MAC
+address may change each time the VF driver is reloaded. You can assign a static
+MAC address in the host machine. This static MAC address will survive
+a VF driver reload.
+
+Driver Buffer Overflow Fix
+--------------------------
+The fix to resolve CVE-2016-8105, referenced in Intel SA-00069
+https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00069.html
+is included in this and future versions of the driver.
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+Due to the default ARP behavior on Linux, it is not possible to have one system
+on two IP networks in the same Ethernet broadcast domain (non-partitioned
+switch) behave as expected. All Ethernet interfaces will respond to IP traffic
+for any IP address assigned to the system. This results in unbalanced receive
+traffic.
+
+If you have multiple interfaces in a server, either turn on ARP filtering by
+entering::
+
+    # echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+
+NOTE:
+  This setting is not saved across reboots. The configuration change can be
+  made permanent by adding the following line to the file /etc/sysctl.conf::
+
+    net.ipv4.conf.all.arp_filter = 1
+
+Another alternative is to install the interfaces in separate broadcast domains
+(either in different switches or in a switch partitioned to VLANs).
+
+Rx Page Allocation Errors
+-------------------------
+'Page allocation failure. order:0' errors may occur under stress.
+This is caused by the way the Linux kernel reports this stressed condition.

+Identifying Your Adapter
+========================
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+
+Command Line Parameters
+========================
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax::
+
+    modprobe igb [<option>=<VAL1>,<VAL2>,...]
+
+There needs to be a <VAL#> for each network port in the system supported by
+this driver. The values will be applied to each instance, in function order.
+For example::
+
+    modprobe igb max_vfs=2,4
+
+In this case, there are two network ports supported by igb in the system.
+
+NOTE: A descriptor describes a data buffer and attributes related to the data
+buffer. This information is accessed by the hardware.
+
+max_vfs
+-------
+:Valid Range: 0-7
+
+This parameter adds support for SR-IOV. It causes the driver to spawn up to
+max_vfs worth of virtual functions.  If the value is greater than 0 it will
+also force the VMDq parameter to be 1 or more.
+
+The parameters for the driver are referenced by position. Thus, if you have a
+dual port adapter, or more than one adapter in your system, and want N virtual
+functions per port, you must specify a number for each port with each parameter
+separated by a comma. For example::
+
+    modprobe igb max_vfs=4
+
+This will spawn 4 VFs on the first port.
+
+::
+
+    modprobe igb max_vfs=2,4
+
+This will spawn 2 VFs on the first port and 4 VFs on the second port.
+
+NOTE: Caution must be used in loading the driver with these parameters.
+Depending on your system configuration, number of slots, etc., it is impossible
+to predict in all cases where the positions would be on the command line.
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
+and VLAN tag stripping/insertion will remain enabled. Please remove the old
+VLAN filter before the new VLAN filter is added. For example::
+
+    ip link set eth0 vf 0 vlan 100	// set vlan 100 for VF 0
+    ip link set eth0 vf 0 vlan 0	// Delete vlan 100
+    ip link set eth0 vf 0 vlan 200	// set a new vlan 200 for VF 0
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level debug messages displayed in the system logs.
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+    ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+    ip link set mtu 9000 dev eth<x>
+    ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9216. This value coincides
+with the maximum Jumbo Frames size of 9234 bytes.
+
+NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
+poor performance or loss of link.
+
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+
+https://www.kernel.org/pub/software/network/ethtool/
+
+
+Enabling Wake on LAN (WoL)
+--------------------------
+WoL is configured through the ethtool utility.
+
+WoL will be enabled on the system during the next shut down or reboot. For
+this driver version, in order to enable WoL, the igb driver must be loaded
+prior to shutting down or suspending the system.
+
+NOTE: Wake on LAN is only supported on port A of multi-port devices.  Also
+Wake On LAN is not supported for the following device:
+- Intel(R) Gigabit VT Quad Port Server Adapter
+
+
+Multiqueue
+----------
+In this mode, a separate MSI-X vector is allocated for each queue and one for
+"other" interrupts such as link status change and errors. All interrupts are
+throttled via interrupt moderation. Interrupt moderation must be used to avoid
+interrupt storms while the driver is processing one interrupt. The moderation
+value should be at least as large as the expected time for the driver to
+process an interrupt. Multiqueue is off by default.
+
+REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not found,
+the system will fallback to MSI or to Legacy interrupts. This driver supports
+receive multiqueue on all kernels that support MSI-X.
+
+NOTE: On some kernels a reboot is required to switch between single queue mode
+and multiqueue mode or vice-versa.
+
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+
+An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
+spoofed packet is detected, the PF driver will send the following message to
+the system log (displayed by the "dmesg" command):
+Spoof event(s) detected on VF(n), where n = the VF that attempted to do the
+spoofing
+
+
+Setting MAC Address, VLAN and Rate Limit Using IProute2 Tool
+------------------------------------------------------------
+You can set a MAC address of a Virtual Function (VF), a default VLAN and the
+rate limit using the IProute2 tool. Download the latest version of the
+IProute2 tool from Sourceforge if your version does not have all the features
+you require.
+
+Credit Based Shaper (Qav Mode)
+------------------------------
+When enabling the CBS qdisc in the hardware offload mode, traffic shaping using
+the CBS (described in the IEEE 802.1Q-2018 Section 8.6.8.2 and discussed in the
+Annex L) algorithm will run in the i210 controller, so it's more accurate and
+uses less CPU.
+
+When using offloaded CBS, and the traffic rate obeys the configured rate
+(doesn't go above it), CBS should have little to no effect in the latency.
+
+The offloaded version of the algorithm has some limits, caused by how the idle
+slope is expressed in the adapter's registers. It can only represent idle slopes
+in 16.38431 kbps units, which means that if a idle slope of 2576kbps is
+requested, the controller will be configured to use a idle slope of ~2589 kbps,
+because the driver rounds the value up. For more details, see the comments on
+:c:func:`igb_config_tx_modes()`.
+
+NOTE: This feature is exclusive to i210 models.

+
+If the driver is built as a module, the  following optional parameters are
+used by entering them on the command line with the modprobe command using
+this syntax::
+
+    modprobe ixgb [<option>=<VAL1>,<VAL2>,...]
+
+For example, with two 10GbE PCI adapters, entering::
+
+    modprobe ixgb TxDescriptors=80,128
+
+loads the ixgb driver with 80 TX resources for the first adapter and 128 TX
+resources for the second adapter.
+
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+Copybreak
+---------
+:Valid Range: 0-XXXX
+:Default Value: 256
+
+    This is the maximum size of packet that is copied to a new buffer on
+    receive.
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+    This parameter adjusts the level of debug messages displayed in the
+    system logs.
+
+FlowControl
+-----------
+:Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
+:Default Value: 1 if no EEPROM, otherwise read from EEPROM
+
+    This parameter controls the automatic generation(Tx) and response(Rx) to
+    Ethernet PAUSE frames.  There are hardware bugs associated with enabling
+    Tx flow control so beware.
+
+RxDescriptors
+-------------
+:Valid Range: 64-4096
+:Default Value: 1024
+
+    This value is the number of receive descriptors allocated by the driver.
+    Increasing this value allows the driver to buffer more incoming packets.
+    Each descriptor is 16 bytes.  A receive buffer is also allocated for
+    each descriptor and can be either 2048, 4056, 8192, or 16384 bytes,
+    depending on the MTU setting.  When the MTU size is 1500 or less, the
+    receive buffer size is 2048 bytes. When the MTU is greater than 1500 the
+    receive buffer size will be either 4056, 8192, or 16384 bytes.  The
+    maximum MTU size is 16114.
+
+TxDescriptors
+-------------
+:Valid Range: 64-4096
+:Default Value: 256
+
+    This value is the number of transmit descriptors allocated by the driver.
+    Increasing this value allows the driver to queue more transmits.  Each
+    descriptor is 16 bytes.
+
+RxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 72
+
+    This value delays the generation of receive interrupts in units of
+    0.8192 microseconds.  Receive interrupt reduction can improve CPU
+    efficiency if properly tuned for specific network traffic.  Increasing
+    this value adds extra latency to frame reception and can end up
+    decreasing the throughput of TCP traffic.  If the system is reporting
+    dropped receives, this value may be set too high, causing the driver to
+    run out of available receive descriptors.
+
+TxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 32
+
+    This value delays the generation of transmit interrupts in units of
+    0.8192 microseconds.  Transmit interrupt reduction can improve CPU
+    efficiency if properly tuned for specific network traffic.  Increasing
+    this value adds extra latency to frame transmission and can end up
+    decreasing the throughput of TCP traffic.  If this value is set too high,
+    it will cause the driver to run out of available transmit descriptors.
+
+XsumRX
+------
+:Valid Range: 0-1
+:Default Value: 1
+
+    A value of '1' indicates that the driver should enable IP checksum
+    offload for received packets (both UDP and TCP) to the adapter hardware.
+
+RxFCHighThresh
+--------------
+:Valid Range: 1,536-262,136 (0x600 - 0x3FFF8, 8 byte granularity)
+:Default Value: 196,608 (0x30000)
+
+    Receive Flow control high threshold (when we send a pause frame)
+
+RxFCLowThresh
+-------------
+:Valid Range: 64-262,136 (0x40 - 0x3FFF8, 8 byte granularity)
+:Default Value: 163,840 (0x28000)
+
+    Receive Flow control low threshold (when we send a resume frame)
+
+FCReqTimeout
+------------
+:Valid Range: 1-65535
+:Default Value: 65535
+
+    Flow control request timeout (how long to pause the link partner's tx)
+
+IntDelayEnable
+--------------
+:Value Range: 0,1
+:Default Value: 1
+
+    Interrupt Delay, 0 disables transmit interrupt delay and 1 enables it.
+
+
+Improving Performance
+=====================
+
+With the 10 Gigabit server adapters, the default Linux configuration will
+very likely limit the total available throughput artificially.  There is a set
+of configuration changes that, when applied together, will increase the ability
+of Linux to transmit and receive data.  The following enhancements were
+originally acquired from settings published at http://www.spec.org/web99/ for
+various submitted results using Linux.
+
+NOTE:
+  These changes are only suggestions, and serve as a starting point for
+  tuning your network performance.
+
+The changes are made in three major ways, listed in order of greatest effect:
+
+- Use ip link to modify the mtu (maximum transmission unit) and the txqueuelen
+  parameter.
+- Use sysctl to modify /proc parameters (essentially kernel tuning)
+- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
+  transmit burst lengths on the bus.
+
+NOTE:
+  setpci modifies the adapter's configuration registers to allow it to read
+  up to 4k bytes at a time (for transmits).  However, for some systems the
+  behavior after modifying this register may be undefined (possibly errors of
+  some kind).  A power-cycle, hard reset or explicitly setting the e6 register
+  back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a
+  stable configuration.
+
+- COPY these lines and paste them into ixgb_perf.sh:
+
+::
+
+  #!/bin/bash
+  echo "configuring network performance , edit this file to change the interface
+  or device ID of 10GbE card"
+  # set mmrbc to 4k reads, modify only Intel 10GbE device IDs
+  # replace 1a48 with appropriate 10GbE device's ID installed on the system,
+  # if needed.
+  setpci -d 8086:1a48 e6.b=2e
+  # set the MTU (max transmission unit) - it requires your switch and clients
+  # to change as well.
+  # set the txqueuelen
+  # your ixgb adapter should be loaded as eth1 for this to work, change if needed
+  ip li set dev eth1 mtu 9000 txqueuelen 1000 up
+  # call the sysctl utility to modify /proc/sys entries
+  sysctl -p ./sysctl_ixgb.conf
+
+- COPY these lines and paste them into sysctl_ixgb.conf:
+
+::
+
+  # some of the defaults may be different for your kernel
+  # call this file with sysctl -p <this file>
+  # these are just suggested values that worked well to increase throughput in
+  # several network benchmark tests, your mileage may vary
+
+  ### IPV4 specific settings
+  # turn TCP timestamp support off, default 1, reduces CPU use
+  net.ipv4.tcp_timestamps = 0
+  # turn SACK support off, default on
+  # on systems with a VERY fast bus -> memory interface this is the big gainer
+  net.ipv4.tcp_sack = 0
+  # set min/default/max TCP read buffer, default 4096 87380 174760
+  net.ipv4.tcp_rmem = 10000000 10000000 10000000
+  # set min/pressure/max TCP write buffer, default 4096 16384 131072
+  net.ipv4.tcp_wmem = 10000000 10000000 10000000
+  # set min/pressure/max TCP buffer space, default 31744 32256 32768
+  net.ipv4.tcp_mem = 10000000 10000000 10000000
+
+  ### CORE settings (mostly for socket and UDP effect)
+  # set maximum receive socket buffer size, default 131071
+  net.core.rmem_max = 524287
+  # set maximum send socket buffer size, default 131071
+  net.core.wmem_max = 524287
+  # set default receive socket buffer size, default 65535
+  net.core.rmem_default = 524287
+  # set default send socket buffer size, default 65535
+  net.core.wmem_default = 524287
+  # set maximum amount of option memory buffers, default 10240
+  net.core.optmem_max = 524287
+  # set number of unprocessed input packets before kernel starts dropping them; default 300
+  net.core.netdev_max_backlog = 300000
+
+Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface
+your ixgb driver is using and/or replace '1a48' with appropriate 10GbE device's
+ID installed on the system.
+
+NOTE:
+  Unless these scripts are added to the boot process, these changes will
+  only last only until the next system reboot.
+
+
+Resolving Slow UDP Traffic
+--------------------------
+If your server does not seem to be able to receive UDP traffic as fast as it
+can receive TCP traffic, it could be because Linux, by default, does not set
+the network stack buffers as large as they need to be to support high UDP
+transfer rates.  One way to alleviate this problem is to allow more memory to
+be used by the IP stack to store incoming data.
+
+For instance, use the commands::
+
+    sysctl -w net.core.rmem_max=262143
+
+and::
+
+    sysctl -w net.core.rmem_default=262143
+
+to increase the read buffer memory max and default to 262143 (256k - 1) from
+defaults of max=131071 (128k - 1) and default=65535 (64k - 1).  These variables
+will increase the amount of memory used by the network stack for receives, and
+can be increased significantly more if necessary for your application.
+
+
+Additional Configurations
+=========================
+
+Configuring the Driver on Different Distributions
+-------------------------------------------------
+Configuring a network driver to load properly when the system is started is
+distribution dependent. Typically, the configuration process involves adding
+an alias line to /etc/modprobe.conf as well as editing other system startup
+scripts and/or configuration files.  Many popular Linux distributions ship
+with tools to make these changes for you.  To learn the proper way to
+configure a network device for your system, refer to your distribution
+documentation.  If during this process you are asked for the driver or module
+name, the name for the Linux Base Driver for the Intel 10GbE Family of
+Adapters is ixgb.
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+    dmesg -n 8
+
+NOTE: This setting is not saved across reboots.
+
+Jumbo Frames
+------------
+The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
+enabled by changing the MTU to a value larger than the default of 1500.
+The maximum value for the MTU is 16114.  Use the ip command to
+increase the MTU size.  For example::
+
+    ip li set dev ethx mtu 9000
+
+The maximum MTU setting for Jumbo Frames is 16114.  This value coincides
+with the maximum Jumbo Frames size of 16128.
+
+Ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information.  The ethtool
+version 1.6 or later is required for this functionality.
+
+The latest release of ethtool can be found from
+https://www.kernel.org/pub/software/network/ethtool/
+
+NOTE:
+  The ethtool version 1.6 only supports a limited set of ethtool options.
+  Support for a more complete ethtool feature set can be enabled by
+  upgrading to the latest version.
+
+NAPI
+----
+NAPI (Rx polling mode) is supported in the ixgb driver.
+
+See https://wiki.linuxfoundation.org/networking/napi for more information on
+NAPI.
+
+
+Known Issues/Troubleshooting
+============================
+
+NOTE:
+  After installing the driver, if your Intel Network Connection is not
+  working, verify in the "In This Release" section of the readme that you have
+  installed the correct driver.
+
+Cable Interoperability Issue with Fujitsu XENPAK Module in SmartBits Chassis
+----------------------------------------------------------------------------
+Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
+Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
+chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
+The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
+Server adapter or the SmartBits. If this situation occurs using a different
+cable assembly may resolve the issue.
+
+Cable Interoperability Issues with HP Procurve 3400cl Switch Port
+-----------------------------------------------------------------
+Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
+adapter is connected to an HP Procurve 3400cl switch port using short cables
+(1 m or shorter). If this situation occurs, using a longer cable may resolve
+the issue.
+
+Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
+Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
+errors may be received either by the CX4 Server adapter or at the switch. If
+this situation occurs, using a different cable assembly may resolve the issue.
+
+Jumbo Frames System Requirement
+-------------------------------
+Memory allocation failures have been observed on Linux systems with 64 MB
+of RAM or less that are running Jumbo Frames.  If you are using Jumbo
+Frames, your system may require more than the advertised minimum
+requirement of 64 MB of system memory.
+
+Performance Degradation with Jumbo Frames
+-----------------------------------------
+Degradation in throughput performance may be observed in some Jumbo frames
+environments.  If this is observed, increasing the application's socket buffer
+size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
+See the specific application manual and /usr/src/linux*/Documentation/
+networking/ip-sysctl.txt for more details.
+
+Allocating Rx Buffers when Using Jumbo Frames
+---------------------------------------------
+Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
+the available memory is heavily fragmented. This issue may be seen with PCI-X
+adapters or with packet split disabled. This can be reduced or eliminated
+by changing the amount of available memory for receive buffer allocation, by
+increasing /proc/sys/vm/min_free_kbytes.
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+Due to the default ARP behavior on Linux, it is not possible to have
+one system on two IP networks in the same Ethernet broadcast domain
+(non-partitioned switch) behave as expected.  All Ethernet interfaces
+will respond to IP traffic for any IP address assigned to the system.
+This results in unbalanced receive traffic.
+
+If you have multiple interfaces in a server, do either of the following:
+
+  - Turn on ARP filtering by entering::
+
+      echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+
+  - Install the interfaces in separate broadcast domains - either in
+    different switches or in a switch partitioned to VLANs.
+
+UDP Stress Test Dropped Packet Issue
+--------------------------------------
+Under small packets UDP stress test with 10GbE driver, the Linux system
+may drop UDP packets due to the fullness of socket buffers. You may want
+to change the driver's Flow Control variables to the minimum value for
+controlling packet reception.
+
+Tx Hangs Possible Under Stress
+------------------------------
+Under stress conditions, if TX hangs occur, turning off TSO
+"ethtool -K eth0 tso off" may resolve the problem.

+
+Command Line Parameters
+=======================
+
+max_vfs
+-------
+:Valid Range: 1-63
+
+This parameter adds support for SR-IOV. It causes the driver to spawn up to
+max_vfs worth of virtual functions.
+If the value is greater than 0 it will also force the VMDq parameter to be 1 or
+more.
+
+NOTE: This parameter is only used on kernel 3.7.x and below. On kernel 3.8.x
+and above, use sysfs to enable VFs. Also, for Red Hat distributions, this
+parameter is only used on version 6.6 and older. For version 6.7 and newer, use
+sysfs. For example::
+
+  #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs // enable VFs
+  #echo 0 > /sys/class/net/$dev/device/sriov_numvfs               //disable VFs
+
+The parameters for the driver are referenced by position. Thus, if you have a
+dual port adapter, or more than one adapter in your system, and want N virtual
+functions per port, you must specify a number for each port with each parameter
+separated by a comma. For example::
+
+  modprobe ixgbe max_vfs=4
+
+This will spawn 4 VFs on the first port.
+
+::
+
+  modprobe ixgbe max_vfs=2,4
+
+This will spawn 2 VFs on the first port and 4 VFs on the second port.
+
+NOTE: Caution must be used in loading the driver with these parameters.
+Depending on your system configuration, number of slots, etc., it is impossible
+to predict in all cases where the positions would be on the command line.
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
+and VLAN tag stripping/insertion will remain enabled. Please remove the old
+VLAN filter before the new VLAN filter is added. For example,
+
+::
+
+  ip link set eth0 vf 0 vlan 100 // set VLAN 100 for VF 0
+  ip link set eth0 vf 0 vlan 0   // Delete VLAN 100
+  ip link set eth0 vf 0 vlan 200 // set a new VLAN 200 for VF 0
+
+With kernel 3.6, the driver supports the simultaneous usage of max_vfs and DCB
+features, subject to the constraints described below. Prior to kernel 3.6, the
+driver did not support the simultaneous operation of max_vfs greater than 0 and
+the DCB features (multiple traffic classes utilizing Priority Flow Control and
+Extended Transmission Selection).
+
+When DCB is enabled, network traffic is transmitted and received through
+multiple traffic classes (packet buffers in the NIC). The traffic is associated
+with a specific class based on priority, which has a value of 0 through 7 used
+in the VLAN tag. When SR-IOV is not enabled, each traffic class is associated
+with a set of receive/transmit descriptor queue pairs. The number of queue
+pairs for a given traffic class depends on the hardware configuration. When
+SR-IOV is enabled, the descriptor queue pairs are grouped into pools. The
+Physical Function (PF) and each Virtual Function (VF) is allocated a pool of
+receive/transmit descriptor queue pairs. When multiple traffic classes are
+configured (for example, DCB is enabled), each pool contains a queue pair from
+each traffic class. When a single traffic class is configured in the hardware,
+the pools contain multiple queue pairs from the single traffic class.
+
+The number of VFs that can be allocated depends on the number of traffic
+classes that can be enabled. The configurable number of traffic classes for
+each enabled VF is as follows:
+0 - 15 VFs = Up to 8 traffic classes, depending on device support
+16 - 31 VFs = Up to 4 traffic classes
+32 - 63 VFs = 1 traffic class
+
+When VFs are configured, the PF is allocated one pool as well. The PF supports
+the DCB features with the constraint that each traffic class will only use a
+single queue pair. When zero VFs are configured, the PF can support multiple
+queue pairs per traffic class.
+
+allow_unsupported_sfp
+---------------------
+:Valid Range: 0,1
+:Default Value: 0 (disabled)
+
+This parameter allows unsupported and untested SFP+ modules on 82599-based
+adapters, as long as the type of module is known to the driver.
+
+debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level of debug messages displayed in the system
+logs.
+
+
+Additional Features and Configurations
+======================================
+
+Flow Control
+------------
+Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
+receiving and transmitting pause frames for ixgbe. When transmit is enabled,
+pause frames are generated when the receive packet buffer crosses a predefined
+threshold. When receive is enabled, the transmit unit will halt for the time
+delay specified when a pause frame is received.
+
+NOTE: You must have a flow control capable link partner.
+
+Flow Control is enabled by default.
+
+Use ethtool to change the flow control settings. To enable or disable Rx or
+Tx Flow Control::
+
+  ethtool -A eth? rx <on|off> tx <on|off>
+
+Note: This command only enables or disables Flow Control if auto-negotiation is
+disabled. If auto-negotiation is enabled, this command changes the parameters
+used for auto-negotiation with the link partner.
+
+To enable or disable auto-negotiation::
+
+  ethtool -s eth? autoneg <on|off>
+
+Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
+on your device, you may not be able to change the auto-negotiation setting.
+
+NOTE: For 82598 backplane cards entering 1 gigabit mode, flow control default
+behavior is changed to off. Flow control in 1 gigabit mode on these devices can
+lead to transmit hangs.
+
+Intel(R) Ethernet Flow Director
+-------------------------------
+The Intel Ethernet Flow Director performs the following tasks:
+
+- Directs receive packets according to their flows to different queues.
+- Enables tight control on routing a flow in the platform.
+- Matches flows and CPU cores for flow affinity.
+- Supports multiple parameters for flexible flow classification and load
+  balancing (in SFP mode only).
+
+NOTE: Intel Ethernet Flow Director masking works in the opposite manner from
+subnet masking. In the following command::
+
+  #ethtool -N eth11 flow-type ip4 src-ip 172.4.1.2 m 255.0.0.0 dst-ip \
+  172.21.1.1 m 255.128.0.0 action 31
+
+The src-ip value that is written to the filter will be 0.4.1.2, not 172.0.0.0
+as might be expected. Similarly, the dst-ip value written to the filter will be
+0.21.1.1, not 172.0.0.0.
+
+To enable or disable the Intel Ethernet Flow Director::
+
+  # ethtool -K ethX ntuple <on|off>
+
+When disabling ntuple filters, all the user programmed filters are flushed from
+the driver cache and hardware. All needed filters must be re-added when ntuple
+is re-enabled.
+
+To add a filter that directs packet to queue 2, use -U or -N switch::
+
+  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+  192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
+
+To see the list of filters currently present::
+
+  # ethtool <-u|-n> ethX
+
+Sideband Perfect Filters
+------------------------
+Sideband Perfect Filters are used to direct traffic that matches specified
+characteristics. They are enabled through ethtool's ntuple interface. To add a
+new filter use the following command::
+
+  ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
+  dst-port <port> action <queue>
+
+Where:
+  <device> - the ethernet device to program
+  <type> - can be ip4, tcp4, udp4, or sctp4
+  <ip> - the IP address to match on
+  <port> - the port number to match on
+  <queue> - the queue to direct traffic towards (-1 discards the matched traffic)
+
+Use the following command to delete a filter::
+
+  ethtool -U <device> delete <N>
+
+Where <N> is the filter id displayed when printing all the active filters, and
+may also have been specified using "loc <N>" when adding the filter.
+
+The following example matches TCP traffic sent from 192.168.0.1, port 5300,
+directed to 192.168.0.5, port 80, and sends it to queue 7::
+
+  ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
+  src-port 5300 dst-port 80 action 7
+
+For each flow-type, the programmed filters must all have the same matching
+input set. For example, issuing the following two commands is acceptable::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
+
+Issuing the next two commands, however, is not acceptable, since the first
+specifies src-ip and the second specifies dst-ip::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
+
+The second command will fail with an error. You may program multiple filters
+with the same fields, using different values, but, on one device, you may not
+program two TCP4 filters with different matching fields.
+
+Matching on a sub-portion of a field is not supported by the ixgbe driver, thus
+partial mask fields are not supported.
+
+To create filters that direct traffic to a specific Virtual Function, use the
+"user-def" parameter. Specify the user-def as a 64 bit value, where the lower 32
+bits represents the queue number, while the next 8 bits represent which VF.
+Note that 0 is the PF, so the VF identifier is offset by 1. For example::
+
+  ... user-def 0x800000002 ...
+
+specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
+that VF.
+
+Note that these filters will not break internal routing rules, and will not
+route traffic that otherwise would not have been sent to the specified Virtual
+Function.
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+  ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+  ip link set mtu 9000 dev eth<x>
+  ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file::
+
+  /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
+  /etc/sysconfig/network/<config_file> // for SLES
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9710. This value coincides
+with the maximum Jumbo Frames size of 9728 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+NOTE: For 82599-based network connections, if you are enabling jumbo frames in
+a virtual function (VF), jumbo frames must first be enabled in the physical
+function (PF). The VF MTU setting cannot be larger than the PF MTU.
+
+Generic Receive Offload, aka GRO
+--------------------------------
+The driver supports the in-kernel software implementation of GRO. GRO has
+shown that by coalescing Rx traffic into larger chunks of data, CPU
+utilization can be significantly reduced when under large Rx load. GRO is an
+evolution of the previously-used LRO interface. GRO is able to coalesce
+other protocols besides TCP. It's also safe to use with configurations that
+are problematic for LRO, namely bridging and iSCSI.
+
+Data Center Bridging (DCB)
+--------------------------
+NOTE:
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.
+
+DCB is a configuration Quality of Service implementation in hardware. It uses
+the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
+different priorities that traffic can be filtered into. It also enables
+priority flow control (802.1Qbb) which can limit or eliminate the number of
+dropped packets during network stress. Bandwidth can be allocated to each of
+these priorities, which is enforced at the hardware level (802.1Qaz).
+
+Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
+802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
+and can accept settings from a DCBX capable peer. Software configuration of
+DCBX parameters via dcbtool/lldptool are not supported.
+
+The ixgbe driver implements the DCB netlink interface layer to allow user-space
+to communicate with the driver and query DCB configuration for the port.
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+FCoE
+----
+The ixgbe driver supports Fiber Channel over Ethernet (FCoE) and Data Center
+Bridging (DCB). This code has no default effect on the regular driver
+operation. Configuring DCB and FCoE is outside the scope of this README. Refer
+to http://www.open-fcoe.org/ for FCoE project information and contact
+ixgbe-eedc@lists.sourceforge.net for DCB information.
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+
+An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
+spoofed packet is detected, the PF driver will send the following message to
+the system log (displayed by the "dmesg" command)::
+
+  ixgbe ethX: ixgbe_spoof_check: n spoofed packets detected
+
+where "x" is the PF interface number; and "n" is number of spoofed packets.
+NOTE: This feature can be disabled for a specific Virtual Function (VF)::
+
+  ip link set <pf dev> vf <vf id> spoofchk {off|on}
+
+IPsec Offload
+-------------
+The ixgbe driver supports IPsec Hardware Offload.  When creating Security
+Associations with "ip xfrm ..." the 'offload' tag option can be used to
+register the IPsec SA with the driver in order to get higher throughput in
+the secure communications.
+
+The offload is also supported for ixgbe's VFs, but the VF must be set as
+'trusted' and the support must be enabled with::
+
+  ethtool --set-priv-flags eth<x> vf-ipsec on
+  ip link set eth<x> vf <y> trust on
+

+
+Overview
+========
+
+Resource virtualization unit (RVU) on Marvell's OcteonTX2 SOC maps HW
+resources from the network, crypto and other functional blocks into
+PCI-compatible physical and virtual functions. Each functional block
+again has multiple local functions (LFs) for provisioning to PCI devices.
+RVU supports multiple PCIe SRIOV physical functions (PFs) and virtual
+functions (VFs). PF0 is called the administrative / admin function (AF)
+and has privileges to provision RVU functional block's LFs to each of the
+PF/VF.
+
+RVU managed networking functional blocks
+ - Network pool or buffer allocator (NPA)
+ - Network interface controller (NIX)
+ - Network parser CAM (NPC)
+ - Schedule/Synchronize/Order unit (SSO)
+ - Loopback interface (LBK)
+
+RVU managed non-networking functional blocks
+ - Crypto accelerator (CPT)
+ - Scheduled timers unit (TIM)
+ - Schedule/Synchronize/Order unit (SSO)
+   Used for both networking and non networking usecases
+
+Resource provisioning examples
+ - A PF/VF with NIX-LF & NPA-LF resources works as a pure network device
+ - A PF/VF with CPT-LF resource works as a pure crypto offload device.
+
+RVU functional blocks are highly configurable as per software requirements.
+
+Firmware setups following stuff before kernel boots
+ - Enables required number of RVU PFs based on number of physical links.
+ - Number of VFs per PF are either static or configurable at compile time.
+   Based on config, firmware assigns VFs to each of the PFs.
+ - Also assigns MSIX vectors to each of PF and VFs.
+ - These are not changed after kernel boot.
+
+Drivers
+=======
+
+Linux kernel will have multiple drivers registering to different PF and VFs
+of RVU. Wrt networking there will be 3 flavours of drivers.
+
+Admin Function driver
+---------------------
+
+As mentioned above RVU PF0 is called the admin function (AF), this driver
+supports resource provisioning and configuration of functional blocks.
+Doesn't handle any I/O. It sets up few basic stuff but most of the
+funcionality is achieved via configuration requests from PFs and VFs.
+
+PF/VFs communicates with AF via a shared memory region (mailbox). Upon
+receiving requests AF does resource provisioning and other HW configuration.
+AF is always attached to host kernel, but PFs and their VFs may be used by host
+kernel itself, or attached to VMs or to userspace applications like
+DPDK etc. So AF has to handle provisioning/configuration requests sent
+by any device from any domain.
+
+AF driver also interacts with underlying firmware to
+ - Manage physical ethernet links ie CGX LMACs.
+ - Retrieve information like speed, duplex, autoneg etc
+ - Retrieve PHY EEPROM and stats.
+ - Configure FEC, PAM modes
+ - etc
+
+From pure networking side AF driver supports following functionality.
+ - Map a physical link to a RVU PF to which a netdev is registered.
+ - Attach NIX and NPA block LFs to RVU PF/VF which provide buffer pools, RQs, SQs
+   for regular networking functionality.
+ - Flow control (pause frames) enable/disable/config.
+ - HW PTP timestamping related config.
+ - NPC parser profile config, basically how to parse pkt and what info to extract.
+ - NPC extract profile config, what to extract from the pkt to match data in MCAM entries.
+ - Manage NPC MCAM entries, upon request can frame and install requested packet forwarding rules.
+ - Defines receive side scaling (RSS) algorithms.
+ - Defines segmentation offload algorithms (eg TSO)
+ - VLAN stripping, capture and insertion config.
+ - SSO and TIM blocks config which provide packet scheduling support.
+ - Debugfs support, to check current resource provising, current status of
+   NPA pools, NIX RQ, SQ and CQs, various stats etc which helps in debugging issues.
+ - And many more.
+
+Physical Function driver
+------------------------
+
+This RVU PF handles IO, is mapped to a physical ethernet link and this
+driver registers a netdev. This supports SR-IOV. As said above this driver
+communicates with AF with a mailbox. To retrieve information from physical
+links this driver talks to AF and AF gets that info from firmware and responds
+back ie cannot talk to firmware directly.
+
+Supports ethtool for configuring links, RSS, queue count, queue size,
+flow control, ntuple filters, dump PHY EEPROM, config FEC etc.
+
+Virtual Function driver
+-----------------------
+
+There are two types VFs, VFs that share the physical link with their parent
+SR-IOV PF and the VFs which work in pairs using internal HW loopback channels (LBK).
+
+Type1:
+ - These VFs and their parent PF share a physical link and used for outside communication.
+ - VFs cannot communicate with AF directly, they send mbox message to PF and PF
+   forwards that to AF. AF after processing, responds back to PF and PF forwards
+   the reply to VF.
+ - From functionality point of view there is no difference between PF and VF as same type
+   HW resources are attached to both. But user would be able to configure few stuff only
+   from PF as PF is treated as owner/admin of the link.
+
+Type2:
+ - RVU PF0 ie admin function creates these VFs and maps them to loopback block's channels.
+ - A set of two VFs (VF0 & VF1, VF2 & VF3 .. so on) works as a pair ie pkts sent out of
+   VF0 will be received by VF1 and viceversa.
+ - These VFs can be used by applications or virtual machines to communicate between them
+   without sending traffic outside. There is no switch present in HW, hence the support
+   for loopback VFs.
+ - These communicate directly with AF (PF0) via mbox.
+
+Except for the IO channels or links used for packet reception and transmission there is
+no other difference between these VF types. AF driver takes care of IO channel mapping,
+hence same VF driver works for both types of devices.
+
+Basic packet flow
+=================
+
+Ingress
+-------
+
+1. CGX LMAC receives packet.
+2. Forwards the packet to the NIX block.
+3. Then submitted to NPC block for parsing and then MCAM lookup to get the destination RVU device.
+4. NIX LF attached to the destination RVU device allocates a buffer from RQ mapped buffer pool of NPA block LF.
+5. RQ may be selected by RSS or by configuring MCAM rule with a RQ number.
+6. Packet is DMA'ed and driver is notified.
+
+Egress
+------
+
+1. Driver prepares a send descriptor and submits to SQ for transmission.
+2. The SQ is already configured (by AF) to transmit on a specific link/channel.
+3. The SQ descriptor ring is maintained in buffers allocated from SQ mapped pool of NPA block LF.
+4. NIX block transmits the pkt on the designated channel.
+5. NPC MCAM entries can be installed to divert pkt onto a different channel.

+Enabling the driver and kconfig options
+================================================
+
+| mlx5 core is modular and most of the major mlx5 core driver features can be selected (compiled in/out)
+| at build time via kernel Kconfig flags.
+| Basic features, ethernet net device rx/tx offloads and XDP, are available with the most basic flags
+| CONFIG_MLX5_CORE=y/m and CONFIG_MLX5_CORE_EN=y.
+| For the list of advanced features please see below.
+
+**CONFIG_MLX5_CORE=(y/m/n)** (module mlx5_core.ko)
+
+|    The driver can be enabled by choosing CONFIG_MLX5_CORE=y/m in kernel config.
+|    This will provide mlx5 core driver for mlx5 ulps to interface with (mlx5e, mlx5_ib).
+
+
+**CONFIG_MLX5_CORE_EN=(y/n)**
+
+|    Choosing this option will allow basic ethernet netdevice support with all of the standard rx/tx offloads.
+|    mlx5e is the mlx5 ulp driver which provides netdevice kernel interface, when chosen, mlx5e will be
+|    built-in into mlx5_core.ko.
+
+
+**CONFIG_MLX5_EN_ARFS=(y/n)**
+
+|     Enables Hardware-accelerated receive flow steering (arfs) support, and ntuple filtering.
+|     https://community.mellanox.com/s/article/howto-configure-arfs-on-connectx-4
+
+
+**CONFIG_MLX5_EN_RXNFC=(y/n)**
+
+|    Enables ethtool receive network flow classification, which allows user defined
+|    flow rules to direct traffic into arbitrary rx queue via ethtool set/get_rxnfc API.
+
+
+**CONFIG_MLX5_CORE_EN_DCB=(y/n)**:
+
+|    Enables `Data Center Bridging (DCB) Support <https://community.mellanox.com/s/article/howto-auto-config-pfc-and-ets-on-connectx-4-via-lldp-dcbx>`_.
+
+
+**CONFIG_MLX5_MPFS=(y/n)**
+
+|    Ethernet Multi-Physical Function Switch (MPFS) support in ConnectX NIC.
+|    MPFs is required for when `Multi-Host <http://www.mellanox.com/page/multihost>`_ configuration is enabled to allow passing
+|    user configured unicast MAC addresses to the requesting PF.
+
+
+**CONFIG_MLX5_ESWITCH=(y/n)**
+
+|    Ethernet SRIOV E-Switch support in ConnectX NIC. E-Switch provides internal SRIOV packet steering
+|    and switching for the enabled VFs and PF in two available modes:
+|           1) `Legacy SRIOV mode (L2 mac vlan steering based) <https://community.mellanox.com/s/article/howto-configure-sr-iov-for-connectx-4-connectx-5-with-kvm--ethernet-x>`_.
+|           2) `Switchdev mode (eswitch offloads) <https://www.mellanox.com/related-docs/prod_software/ASAP2_Hardware_Offloading_for_vSwitches_User_Manual_v4.4.pdf>`_.
+
+
+**CONFIG_MLX5_CORE_IPOIB=(y/n)**
+
+|    IPoIB offloads & acceleration support.
+|    Requires CONFIG_MLX5_CORE_EN to provide an accelerated interface for the rdma
+|    IPoIB ulp netdevice.
+
+
+**CONFIG_MLX5_FPGA=(y/n)**
+
+|    Build support for the Innova family of network cards by Mellanox Technologies.
+|    Innova network cards are comprised of a ConnectX chip and an FPGA chip on one board.
+|    If you select this option, the mlx5_core driver will include the Innova FPGA core and allow
+|    building sandbox-specific client drivers.
+
+
+**CONFIG_MLX5_EN_IPSEC=(y/n)**
+
+|    Enables `IPSec XFRM cryptography-offload accelaration <http://www.mellanox.com/related-docs/prod_software/Mellanox_Innova_IPsec_Ethernet_Adapter_Card_User_Manual.pdf>`_.
+
+**CONFIG_MLX5_EN_TLS=(y/n)**
+
+|   TLS cryptography-offload accelaration.
+
+
+**CONFIG_MLX5_INFINIBAND=(y/n/m)** (module mlx5_ib.ko)
+
+|   Provides low-level InfiniBand/RDMA and `RoCE <https://community.mellanox.com/s/article/recommended-network-configuration-examples-for-roce-deployment>`_ support.
+
+
+**External options** ( Choose if the corresponding mlx5 feature is required )
+
+- CONFIG_PTP_1588_CLOCK: When chosen, mlx5 ptp support will be enabled
+- CONFIG_VXLAN: When chosen, mlx5 vxlan support will be enabled.
+- CONFIG_MLXFW: When chosen, mlx5 firmware flashing support will be enabled (via devlink and ethtool).
+
+Devlink info
+============
+
+The devlink info reports the running and stored firmware versions on device.
+It also prints the device PSID which represents the HCA board type ID.
+
+User command example::
+
+   $ devlink dev info pci/0000:00:06.0
+      pci/0000:00:06.0:
+      driver mlx5_core
+      versions:
+         fixed:
+            fw.psid MT_0000000009
+         running:
+            fw.version 16.26.0100
+         stored:
+            fw.version 16.26.0100
+
+Devlink parameters
+==================
+
+flow_steering_mode: Device flow steering mode
+---------------------------------------------
+The flow steering mode parameter controls the flow steering mode of the driver.
+Two modes are supported:
+1. 'dmfs' - Device managed flow steering.
+2. 'smfs  - Software/Driver managed flow steering.
+
+In DMFS mode, the HW steering entities are created and managed through the
+Firmware.
+In SMFS mode, the HW steering entities are created and managed though by
+the driver directly into Hardware without firmware intervention.
+
+SMFS mode is faster and provides better rule inserstion rate compared to default DMFS mode.
+
+User command examples:
+
+- Set SMFS flow steering mode::
+
+    $ devlink dev param set pci/0000:06:00.0 name flow_steering_mode value "smfs" cmode runtime
+
+- Read device flow steering mode::
+
+    $ devlink dev param show pci/0000:06:00.0 name flow_steering_mode
+      pci/0000:06:00.0:
+      name flow_steering_mode type driver-specific
+      values:
+         cmode runtime value smfs
+
+enable_roce: RoCE enablement state
+----------------------------------
+RoCE enablement state controls driver support for RoCE traffic.
+When RoCE is disabled, there is no gid table, only raw ethernet QPs are supported and traffic on the well known UDP RoCE port is handled as raw ethernet traffic.
+
+To change RoCE enablement state a user must change the driverinit cmode value and run devlink reload.
+
+User command examples:
+
+- Disable RoCE::
+
+    $ devlink dev param set pci/0000:06:00.0 name enable_roce value false cmode driverinit
+    $ devlink dev reload pci/0000:06:00.0
+
+- Read RoCE enablement state::
+
+    $ devlink dev param show pci/0000:06:00.0 name enable_roce
+      pci/0000:06:00.0:
+      name enable_roce type generic
+      values:
+         cmode driverinit value true
+
+Devlink health reporters
+========================
+
+tx reporter
+-----------
+The tx reporter is responsible for reporting and recovering of the following two error scenarios:
+
+- TX timeout
+    Report on kernel tx timeout detection.
+    Recover by searching lost interrupts.
+- TX error completion
+    Report on error tx completion.
+    Recover by flushing the TX queue and reset it.
+
+TX reporter also support on demand diagnose callback, on which it provides
+real time information of its send queues status.
+
+User commands examples:
+
+- Diagnose send queues status::
+
+    $ devlink health diagnose pci/0000:82:00.0 reporter tx
+
+NOTE: This command has valid output only when interface is up, otherwise the command has empty output.
+
+- Show number of tx errors indicated, number of recover flows ended successfully,
+  is autorecover enabled and graceful period from last recover::
+
+    $ devlink health show pci/0000:82:00.0 reporter tx
+
+rx reporter
+-----------
+The rx reporter is responsible for reporting and recovering of the following two error scenarios:
+
+- RX queues initialization (population) timeout
+    RX queues descriptors population on ring initialization is done in
+    napi context via triggering an irq, in case of a failure to get
+    the minimum amount of descriptors, a timeout would occur and it
+    could be recoverable by polling the EQ (Event Queue).
+- RX completions with errors (reported by HW on interrupt context)
+    Report on rx completion error.
+    Recover (if needed) by flushing the related queue and reset it.
+
+RX reporter also supports on demand diagnose callback, on which it
+provides real time information of its receive queues status.
+
+- Diagnose rx queues status, and corresponding completion queue::
+
+    $ devlink health diagnose pci/0000:82:00.0 reporter rx
+
+NOTE: This command has valid output only when interface is up, otherwise the command has empty output.
+
+- Show number of rx errors indicated, number of recover flows ended successfully,
+  is autorecover enabled and graceful period from last recover::
+
+    $ devlink health show pci/0000:82:00.0 reporter rx
+
+fw reporter
+-----------
+The fw reporter implements diagnose and dump callbacks.
+It follows symptoms of fw error such as fw syndrome by triggering
+fw core dump and storing it into the dump buffer.
+The fw reporter diagnose command can be triggered any time by the user to check
+current fw status.
+
+User commands examples:
+
+- Check fw heath status::
+
+    $ devlink health diagnose pci/0000:82:00.0 reporter fw
+
+- Read FW core dump if already stored or trigger new one::
+
+    $ devlink health dump show pci/0000:82:00.0 reporter fw
+
+NOTE: This command can run only on the PF which has fw tracer ownership,
+running it on other PF or any VF will return "Operation not permitted".
+
+fw fatal reporter
+-----------------
+The fw fatal reporter implements dump and recover callbacks.
+It follows fatal errors indications by CR-space dump and recover flow.
+The CR-space dump uses vsc interface which is valid even if the FW command
+interface is not functional, which is the case in most FW fatal errors.
+The recover function runs recover flow which reloads the driver and triggers fw
+reset if needed.
+
+User commands examples:
+
+- Run fw recover flow manually::
+
+    $ devlink health recover pci/0000:82:00.0 reporter fw_fatal
+
+- Read FW CR-space dump if already strored or trigger new one::
+
+    $ devlink health dump show pci/0000:82:00.1 reporter fw_fatal
+
+NOTE: This command can run only on PF.
+
+mlx5 tracepoints
+================
+
+mlx5 driver provides internal trace points for tracking and debugging using
+kernel tracepoints interfaces (refer to Documentation/trace/ftrace.rst).
+
+For the list of support mlx5 events check /sys/kernel/debug/tracing/events/mlx5/
+
+tc and eswitch offloads tracepoints:
+
+- mlx5e_configure_flower: trace flower filter actions and cookies offloaded to mlx5::

+======================
+Hyper-V network driver
+======================
+
+Compatibility
+=============
+
+This driver is compatible with Windows Server 2012 R2, 2016 and
+Windows 10.
+
+Features
+========
+
+Checksum offload
+----------------
+  The netvsc driver supports checksum offload as long as the
+  Hyper-V host version does. Windows Server 2016 and Azure
+  support checksum offload for TCP and UDP for both IPv4 and
+  IPv6. Windows Server 2012 only supports checksum offload for TCP.
+
+Receive Side Scaling
+--------------------
+  Hyper-V supports receive side scaling. For TCP & UDP, packets can
+  be distributed among available queues based on IP address and port
+  number.
+
+  For TCP & UDP, we can switch hash level between L3 and L4 by ethtool
+  command. TCP/UDP over IPv4 and v6 can be set differently. The default
+  hash level is L4. We currently only allow switching TX hash level
+  from within the guests.
+
+  On Azure, fragmented UDP packets have high loss rate with L4
+  hashing. Using L3 hashing is recommended in this case.
+
+  For example, for UDP over IPv4 on eth0:
+
+  To include UDP port numbers in hashing::
+
+	ethtool -N eth0 rx-flow-hash udp4 sdfn
+
+  To exclude UDP port numbers in hashing::
+
+	ethtool -N eth0 rx-flow-hash udp4 sd
+
+  To show UDP hash level::
+
+	ethtool -n eth0 rx-flow-hash udp4
+
+Generic Receive Offload, aka GRO
+--------------------------------
+  The driver supports GRO and it is enabled by default. GRO coalesces
+  like packets and significantly reduces CPU usage under heavy Rx
+  load.
+
+Large Receive Offload (LRO), or Receive Side Coalescing (RSC)
+-------------------------------------------------------------
+  The driver supports LRO/RSC in the vSwitch feature. It reduces the per packet
+  processing overhead by coalescing multiple TCP segments when possible. The
+  feature is enabled by default on VMs running on Windows Server 2019 and
+  later. It may be changed by ethtool command::
+
+	ethtool -K eth0 lro on
+	ethtool -K eth0 lro off
+
+SR-IOV support
+--------------
+  Hyper-V supports SR-IOV as a hardware acceleration option. If SR-IOV
+  is enabled in both the vSwitch and the guest configuration, then the
+  Virtual Function (VF) device is passed to the guest as a PCI
+  device. In this case, both a synthetic (netvsc) and VF device are
+  visible in the guest OS and both NIC's have the same MAC address.
+
+  The VF is enslaved by netvsc device.  The netvsc driver will transparently
+  switch the data path to the VF when it is available and up.
+  Network state (addresses, firewall, etc) should be applied only to the
+  netvsc device; the slave device should not be accessed directly in
+  most cases.  The exceptions are if some special queue discipline or
+  flow direction is desired, these should be applied directly to the
+  VF slave device.
+
+Receive Buffer
+--------------
+  Packets are received into a receive area which is created when device
+  is probed. The receive area is broken into MTU sized chunks and each may
+  contain one or more packets. The number of receive sections may be changed
+  via ethtool Rx ring parameters.
+
+  There is a similar send buffer which is used to aggregate packets for sending.
+  The send area is broken into chunks of 6144 bytes, each of section may
+  contain one or more packets. The send buffer is an optimization, the driver
+  will use slower method to handle very large packets or if the send buffer
+  area is exhausted.
+
+XDP support
+-----------
+  XDP (eXpress Data Path) is a feature that runs eBPF bytecode at the early
+  stage when packets arrive at a NIC card. The goal is to increase performance
+  for packet processing, reducing the overhead of SKB allocation and other
+  upper network layers.
+
+  hv_netvsc supports XDP in native mode, and transparently sets the XDP
+  program on the associated VF NIC as well.
+
+  Setting / unsetting XDP program on synthetic NIC (netvsc) propagates to
+  VF NIC automatically. Setting / unsetting XDP program on VF NIC directly
+  is not recommended, also not propagated to synthetic NIC, and may be
+  overwritten by setting of synthetic NIC.
+
+  XDP program cannot run with LRO (RSC) enabled, so you need to disable LRO
+  before running XDP::
+
+	ethtool -K eth0 lro off
+
+  XDP_REDIRECT action is not yet supported.

+  - 2.  Identifying the adapter/interface
+  - 3.  Features supported
+  - 4.  Command line parameters
+  - 5.  Performance suggestions
+  - 6.  Available Downloads
+
+
+1. Introduction
+===============
+This Linux driver supports Neterion's Xframe I PCI-X 1.0 and
+Xframe II PCI-X 2.0 adapters. It supports several features
+such as jumbo frames, MSI/MSI-X, checksum offloads, TSO, UFO and so on.
+See below for complete list of features.
+
+All features are supported for both IPv4 and IPv6.
+
+2. Identifying the adapter/interface
+====================================
+
+a. Insert the adapter(s) in your system.
+b. Build and load driver::
+
+	# insmod s2io.ko
+
+c. View log messages::
+
+	# dmesg | tail -40
+
+You will see messages similar to::
+
+	eth3: Neterion Xframe I 10GbE adapter (rev 3), Version 2.0.9.1, Intr type INTA
+	eth4: Neterion Xframe II 10GbE adapter (rev 2), Version 2.0.9.1, Intr type INTA
+	eth4: Device is on 64 bit 133MHz PCIX(M1) bus
+
+The above messages identify the adapter type(Xframe I/II), adapter revision,
+driver version, interface name(eth3, eth4), Interrupt type(INTA, MSI, MSI-X).
+In case of Xframe II, the PCI/PCI-X bus width and frequency are displayed
+as well.
+
+To associate an interface with a physical adapter use "ethtool -p <ethX>".
+The corresponding adapter's LED will blink multiple times.
+
+3. Features supported
+=====================
+a. Jumbo frames. Xframe I/II supports MTU up to 9600 bytes,
+   modifiable using ip command.
+
+b. Offloads. Supports checksum offload(TCP/UDP/IP) on transmit
+   and receive, TSO.
+
+c. Multi-buffer receive mode. Scattering of packet across multiple
+   buffers. Currently driver supports 2-buffer mode which yields
+   significant performance improvement on certain platforms(SGI Altix,
+   IBM xSeries).
+
+d. MSI/MSI-X. Can be enabled on platforms which support this feature
+   (IA64, Xeon) resulting in noticeable performance improvement(up to 7%
+   on certain platforms).
+
+e. Statistics. Comprehensive MAC-level and software statistics displayed
+   using "ethtool -S" option.
+
+f. Multi-FIFO/Ring. Supports up to 8 transmit queues and receive rings,
+   with multiple steering options.
+
+4. Command line parameters
+==========================
+
+a. tx_fifo_num
+	Number of transmit queues
+
+Valid range: 1-8
+
+Default: 1
+
+b. rx_ring_num
+	Number of receive rings
+
+Valid range: 1-8
+
+Default: 1
+
+c. tx_fifo_len
+	Size of each transmit queue
+
+Valid range: Total length of all queues should not exceed 8192
+
+Default: 4096
+
+d. rx_ring_sz
+	Size of each receive ring(in 4K blocks)
+
+Valid range: Limited by memory on system
+
+Default: 30
+
+e. intr_type
+	Specifies interrupt type. Possible values 0(INTA), 2(MSI-X)
+
+Valid values: 0, 2
+
+Default: 2
+
+5. Performance suggestions
+==========================
+
+General:
+
+a. Set MTU to maximum(9000 for switch setup, 9600 in back-to-back configuration)
+b. Set TCP windows size to optimal value.
+
+For instance, for MTU=1500 a value of 210K has been observed to result in
+good performance::
+
+	# sysctl -w net.ipv4.tcp_rmem="210000 210000 210000"
+	# sysctl -w net.ipv4.tcp_wmem="210000 210000 210000"
+
+For MTU=9000, TCP window size of 10 MB is recommended::
+
+	# sysctl -w net.ipv4.tcp_rmem="10000000 10000000 10000000"
+	# sysctl -w net.ipv4.tcp_wmem="10000000 10000000 10000000"
+
+Transmit performance:
+
+a. By default, the driver respects BIOS settings for PCI bus parameters.
+   However, you may want to experiment with PCI bus parameters
+   max-split-transactions(MOST) and MMRBC (use setpci command).
+
+   A MOST value of 2 has been found optimal for Opterons and 3 for Itanium.
+
+   It could be different for your hardware.
+
+   Set MMRBC to 4K**.
+
+   For example you can set
+
+   For opteron::
+
+	#setpci -d 17d5:* 62=1d
+
+   For Itanium::
+
+	#setpci -d 17d5:* 62=3d
+
+   For detailed description of the PCI registers, please see Xframe User Guide.
+
+b. Ensure Transmit Checksum offload is enabled. Use ethtool to set/verify this
+   parameter.
+
+c. Turn on TSO(using "ethtool -K")::
+
+	# ethtool -K <ethX> tso on
+
+Receive performance:
+
+a. By default, the driver respects BIOS settings for PCI bus parameters.
+   However, you may want to set PCI latency timer to 248::
+
+	#setpci -d 17d5:* LATENCY_TIMER=f8
+
+   For detailed description of the PCI registers, please see Xframe User Guide.
+
+b. Use 2-buffer mode. This results in large performance boost on
+   certain platforms(eg. SGI Altix, IBM xSeries).
+
+c. Ensure Receive Checksum offload is enabled. Use "ethtool -K ethX" command to
+   set/verify this option.
+
+d. Enable NAPI feature(in kernel configuration Device Drivers ---> Network
+   device support --->  Ethernet (10000 Mbit) ---> S2IO 10Gbe Xframe NIC) to
+   bring down CPU utilization.
+
+.. note::
+
+   For AMD opteron platforms with 8131 chipset, MMRBC=1 and MOST=1 are
+   recommended as safe parameters.

+
+1. Introduction
+===============
+
+This Linux driver supports all Neterion's X3100 series 10 GbE PCIe I/O
+Virtualized Server adapters.
+
+The X3100 series supports four modes of operation, configurable via
+firmware:
+
+	- Single function mode
+	- Multi function mode
+	- SRIOV mode
+	- MRIOV mode
+
+The functions share a 10GbE link and the pci-e bus, but hardly anything else
+inside the ASIC. Features like independent hw reset, statistics, bandwidth/
+priority allocation and guarantees, GRO, TSO, interrupt moderation etc are
+supported independently on each function.
+
+(See below for a complete list of features supported for both IPv4 and IPv6)

+Netronome Flow Processor (NFP) Kernel Drivers
+=============================================
+
+Copyright (c) 2019, Netronome Systems, Inc.

+
+Overview
+========
+
+This driver supports Netronome's line of Flow Processor devices,
+including the NFP4000, NFP5000, and NFP6000 models, which are also
+incorporated in the company's family of Agilio SmartNICs. The SR-IOV
+physical and virtual functions for these devices are supported by
+the driver.
+
+Acquiring Firmware
+==================
+
+The NFP4000 and NFP6000 devices require application specific firmware
+to function.  Application firmware can be located either on the host file system
+or in the device flash (if supported by management firmware).
+
+Firmware files on the host filesystem contain card type (`AMDA-*` string), media
+config etc.  They should be placed in `/lib/firmware/netronome` directory to
+load firmware from the host file system.
+
+Firmware for basic NIC operation is available in the upstream
+`linux-firmware.git` repository.
+
+Firmware in NVRAM
+-----------------
+
+Recent versions of management firmware supports loading application
+firmware from flash when the host driver gets probed.  The firmware loading
+policy configuration may be used to configure this feature appropriately.
+
+Devlink or ethtool can be used to update the application firmware on the device
+flash by providing the appropriate `nic_AMDA*.nffw` file to the respective
+command.  Users need to take care to write the correct firmware image for the
+card and media configuration to flash.
+
+Available storage space in flash depends on the card being used.
+
+Dealing with multiple projects
+------------------------------
+
+NFP hardware is fully programmable therefore there can be different
+firmware images targeting different applications.
+
+When using application firmware from host, we recommend placing
+actual firmware files in application-named subdirectories in
+`/lib/firmware/netronome` and linking the desired files, e.g.::
+
+    $ tree /lib/firmware/netronome/
+    /lib/firmware/netronome/
+    ├── bpf
+    │   ├── nic_AMDA0081-0001_1x40.nffw
+    │   └── nic_AMDA0081-0001_4x10.nffw
+    ├── flower
+    │   ├── nic_AMDA0081-0001_1x40.nffw
+    │   └── nic_AMDA0081-0001_4x10.nffw
+    ├── nic
+    │   ├── nic_AMDA0081-0001_1x40.nffw
+    │   └── nic_AMDA0081-0001_4x10.nffw
+    ├── nic_AMDA0081-0001_1x40.nffw -> bpf/nic_AMDA0081-0001_1x40.nffw
+    └── nic_AMDA0081-0001_4x10.nffw -> bpf/nic_AMDA0081-0001_4x10.nffw
+
+    3 directories, 8 files
+
+You may need to use hard instead of symbolic links on distributions
+which use old `mkinitrd` command instead of `dracut` (e.g. Ubuntu).
+
+After changing firmware files you may need to regenerate the initramfs
+image.  Initramfs contains drivers and firmware files your system may
+need to boot.  Refer to the documentation of your distribution to find
+out how to update initramfs.  Good indication of stale initramfs
+is system loading wrong driver or firmware on boot, but when driver is
+later reloaded manually everything works correctly.
+
+Selecting firmware per device
+-----------------------------
+
+Most commonly all cards on the system use the same type of firmware.
+If you want to load specific firmware image for a specific card, you
+can use either the PCI bus address or serial number.  Driver will print
+which files it's looking for when it recognizes a NFP device::
+
+    nfp: Looking for firmware file in order of priority:
+    nfp:  netronome/serial-00-12-34-aa-bb-cc-10-ff.nffw: not found
+    nfp:  netronome/pci-0000:02:00.0.nffw: not found
+    nfp:  netronome/nic_AMDA0081-0001_1x40.nffw: found, loading...
+
+In this case if file (or link) called *serial-00-12-34-aa-bb-5d-10-ff.nffw*
+or *pci-0000:02:00.0.nffw* is present in `/lib/firmware/netronome` this
+firmware file will take precedence over `nic_AMDA*` files.
+
+Note that `serial-*` and `pci-*` files are **not** automatically included
+in initramfs, you will have to refer to documentation of appropriate tools
+to find out how to include them.
+
+Firmware loading policy
+-----------------------
+
+Firmware loading policy is controlled via three HWinfo parameters
+stored as key value pairs in the device flash:
+
+app_fw_from_flash
+    Defines which firmware should take precedence, 'Disk' (0), 'Flash' (1) or
+    the 'Preferred' (2) firmware. When 'Preferred' is selected, the management
+    firmware makes the decision over which firmware will be loaded by comparing
+    versions of the flash firmware and the host supplied firmware.
+    This variable is configurable using the 'fw_load_policy'
+    devlink parameter.
+
+abi_drv_reset
+    Defines if the driver should reset the firmware when
+    the driver is probed, either 'Disk' (0) if firmware was found on disk,
+    'Always' (1) reset or 'Never' (2) reset. Note that the device is always
+    reset on driver unload if firmware was loaded when the driver was probed.
+    This variable is configurable using the 'reset_dev_on_drv_probe'
+    devlink parameter.
+
+abi_drv_load_ifc
+    Defines a list of PF devices allowed to load FW on the device.
+    This variable is not currently user configurable.
+
+Statistics
+==========
+
+Following device statistics are available through the ``ethtool -S`` interface:
+
+.. flat-table:: NFP device statistics
+   :header-rows: 1
+   :widths: 3 1 11
+
+   * - Name
+     - ID
+     - Meaning
+
+   * - dev_rx_discards
+     - 1
+     - Packet can be discarded on the RX path for one of the following reasons:
+
+        * The NIC is not in promisc mode, and the destination MAC address
+          doesn't match the interfaces' MAC address.
+        * The received packet is larger than the max buffer size on the host.
+          I.e. it exceeds the Layer 3 MRU.
+        * There is no freelist descriptor available on the host for the packet.
+          It is likely that the NIC couldn't cache one in time.
+        * A BPF program discarded the packet.
+        * The datapath drop action was executed.
+        * The MAC discarded the packet due to lack of ingress buffer space
+          on the NIC.
+
+   * - dev_rx_errors
+     - 2
+     - A packet can be counted (and dropped) as RX error for the following
+       reasons:
+
+       * A problem with the VEB lookup (only when SR-IOV is used).
+       * A physical layer problem that causes Ethernet errors, like FCS or
+         alignment errors. The cause is usually faulty cables or SFPs.
+
+   * - dev_rx_bytes
+     - 3
+     - Total number of bytes received.
+
+   * - dev_rx_uc_bytes
+     - 4
+     - Unicast bytes received.
+
+   * - dev_rx_mc_bytes
+     - 5
+     - Multicast bytes received.
+
+   * - dev_rx_bc_bytes
+     - 6
+     - Broadcast bytes received.
+
+   * - dev_rx_pkts
+     - 7
+     - Total number of packets received.
+
+   * - dev_rx_mc_pkts
+     - 8
+     - Multicast packets received.
+
+   * - dev_rx_bc_pkts
+     - 9
+     - Broadcast packets received.
+
+   * - dev_tx_discards
+     - 10
+     - A packet can be discarded in the TX direction if the MAC is
+       being flow controlled and the NIC runs out of TX queue space.
+
+   * - dev_tx_errors
+     - 11
+     - A packet can be counted as TX error (and dropped) for one for the
+       following reasons:
+
+       * The packet is an LSO segment, but the Layer 3 or Layer 4 offset
+         could not be determined. Therefore LSO could not continue.
+       * An invalid packet descriptor was received over PCIe.
+       * The packet Layer 3 length exceeds the device MTU.
+       * An error on the MAC/physical layer. Usually due to faulty cables or
+         SFPs.
+       * A CTM buffer could not be allocated.
+       * The packet offset was incorrect and could not be fixed by the NIC.
+
+   * - dev_tx_bytes
+     - 12
+     - Total number of bytes transmitted.
+
+   * - dev_tx_uc_bytes
+     - 13
+     - Unicast bytes transmitted.
+
+   * - dev_tx_mc_bytes
+     - 14
+     - Multicast bytes transmitted.
+
+   * - dev_tx_bc_bytes
+     - 15
+     - Broadcast bytes transmitted.
+
+   * - dev_tx_pkts
+     - 16
+     - Total number of packets transmitted.
+
+   * - dev_tx_mc_pkts
+     - 17
+     - Multicast packets transmitted.
+
+   * - dev_tx_bc_pkts
+     - 18
+     - Broadcast packets transmitted.
+
+Note that statistics unknown to the driver will be displayed as

+Identifying the Adapter
+=======================
+
+To find if one or more Pensando PCI Ethernet devices are installed on the
+host, check for the PCI devices::
+
+  $ lspci -d 1dd8:
+  b5:00.0 Ethernet controller: Device 1dd8:1002
+  b6:00.0 Ethernet controller: Device 1dd8:1002
+
+If such devices are listed as above, then the ionic.ko driver should find
+and configure them for use.  There should be log entries in the kernel
+messages such as these::
+
+  $ dmesg | grep ionic
+  ionic 0000:b5:00.0: 126.016 Gb/s available PCIe bandwidth (8.0 GT/s PCIe x16 link)
+  ionic 0000:b5:00.0 enp181s0: renamed from eth0
+  ionic 0000:b5:00.0 enp181s0: Link up - 100 Gbps
+  ionic 0000:b6:00.0: 126.016 Gb/s available PCIe bandwidth (8.0 GT/s PCIe x16 link)
+  ionic 0000:b6:00.0 enp182s0: renamed from eth0
+  ionic 0000:b6:00.0 enp182s0: Link up - 100 Gbps
+
+Driver and firmware version information can be gathered with either of
+ethtool or devlink tools::
+
+  $ ethtool -i enp181s0
+  driver: ionic
+  version: 5.7.0
+  firmware-version: 1.8.0-28
+  ...
+
+  $ devlink dev info pci/0000:b5:00.0
+  pci/0000:b5:00.0:
+    driver ionic
+    serial_number FLM18420073
+    versions:
+        fixed:

+          asic.rev 0x0
+        running:
+          fw 1.8.0-28
+
+See Documentation/networking/devlink/ionic.rst for more information
+on the devlink dev info data.
+
+Enabling the driver
+===================
+
+The driver is enabled via the standard kernel configuration system,
+using the make command::
+
+  make oldconfig/menuconfig/etc.
+
+The driver is located in the menu structure at:
+
+  -> Device Drivers
+    -> Network device support (NETDEVICES [=y])
+      -> Ethernet driver support
+        -> Pensando devices
+          -> Pensando Ethernet IONIC Support
+
+Configuring the Driver
+======================
+
+MTU
+---
+
+Jumbo frame support is available with a maximim size of 9194 bytes.
+
+Interrupt coalescing
+--------------------
+
+Interrupt coalescing can be configured by changing the rx-usecs value with
+the "ethtool -C" command.  The rx-usecs range is 0-190.  The tx-usecs value
+reflects the rx-usecs value as they are tied together on the same interrupt.
+
+SR-IOV
+------
+
+Minimal SR-IOV support is currently offered and can be enabled by setting
+the sysfs 'sriov_numvfs' value, if supported by your particular firmware
+configuration.
+
+Statistics
+==========
+
+Basic hardware stats
+--------------------
+
+The commands ``netstat -i``, ``ip -s link show``, and ``ifconfig`` show
+a limited set of statistics taken directly from firmware.  For example::
+
+  $ ip -s link show enp181s0
+  7: enp181s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000

+      1384       18       0       0       0       0
+
+ethtool -S
+----------
+
+The statistics shown from the ``ethtool -S`` command includes a combination of
+driver counters and firmware counters, including port and queue specific values.
+The driver values are counters computed by the driver, and the firmware values
+are gathered by the firmware from the port hardware and passed through the
+driver with no further interpretation.

+
+Driver Information and Notes
+============================
+
+Transmit Process
+----------------
+
+The xmit method is invoked when the kernel needs to transmit a packet; it sets
+the descriptors in the ring and informs the DMA engine that there is a packet
+ready to be transmitted.
+
+By default, the driver sets the ``NETIF_F_SG`` bit in the features field of
+the ``net_device`` structure, enabling the scatter-gather feature. This is
+true on chips and configurations where the checksum can be done in hardware.
+
+Once the controller has finished transmitting the packet, timer will be
+scheduled to release the transmit resources.
+
+Receive Process
+---------------
+
+When one or more packets are received, an interrupt happens. The interrupts
+are not queued, so the driver has to scan all the descriptors in the ring
+during the receive process.
+
+This is based on NAPI, so the interrupt handler signals only if there is work
+to be done, and it exits. Then the poll method will be scheduled at some
+future point.
+
+The incoming packets are stored, by the DMA, in a list of pre-allocated socket
+buffers in order to avoid the memcpy (zero-copy).
+
+Interrupt Mitigation
+--------------------
+
+The driver is able to mitigate the number of its DMA interrupts using NAPI for
+the reception on chips older than the 3.50. New chips have an HW RX Watchdog
+used for this mitigation.
+
+Mitigation parameters can be tuned by ethtool.
+
+WoL
+---
+
+Wake up on Lan feature through Magic and Unicast frames are supported for the
+GMAC, GMAC4/5 and XGMAC core.
+
+DMA Descriptors
+---------------
+
+Driver handles both normal and alternate descriptors. The latter has been only
+tested on DesignWare(R) Cores Ethernet MAC Universal version 3.41a and later.
+
+stmmac supports DMA descriptor to operate both in dual buffer (RING) and
+linked-list(CHAINED) mode. In RING each descriptor points to two data buffer
+pointers whereas in CHAINED mode they point to only one data buffer pointer.
+RING mode is the default.
+
+In CHAINED mode each descriptor will have pointer to next descriptor in the
+list, hence creating the explicit chaining in the descriptor itself, whereas
+such explicit chaining is not possible in RING mode.
+
+Extended Descriptors
+--------------------
+
+The extended descriptors give us information about the Ethernet payload when
+it is carrying PTP packets or TCP/UDP/ICMP over IP. These are not available on
+GMAC Synopsys(R) chips older than the 3.50. At probe time the driver will
+decide if these can be actually used. This support also is mandatory for PTPv2
+because the extra descriptors are used for saving the hardware timestamps and
+Extended Status.
+
+Ethtool Support
+---------------
+
+Ethtool is supported. For example, driver statistics (including RMON),
+internal errors can be taken using::
+
+    ethtool -S ethX
+
+Ethtool selftests are also supported. This allows to do some early sanity
+checks to the HW using MAC and PHY loopback mechanisms::
+
+    ethtool -t ethX
+
+Jumbo and Segmentation Offloading
+---------------------------------
+
+Jumbo frames are supported and tested for the GMAC. The GSO has been also
+added but it's performed in software. LRO is not supported.
+
+TSO Support
+-----------
+
+TSO (TCP Segmentation Offload) feature is supported by GMAC > 4.x and XGMAC
+chip family. When a packet is sent through TCP protocol, the TCP stack ensures
+that the SKB provided to the low level driver (stmmac in our case) matches
+with the maximum frame len (IP header + TCP header + payload <= 1500 bytes
+(for MTU set to 1500)). It means that if an application using TCP want to send
+a packet which will have a length (after adding headers) > 1514 the packet
+will be split in several TCP packets: The data payload is split and headers
+(TCP/IP ..) are added. It is done by software.
+
+When TSO is enabled, the TCP stack doesn't care about the maximum frame length
+and provide SKB packet to stmmac as it is. The GMAC IP will have to perform
+the segmentation by it self to match with maximum frame length.
+
+This feature can be enabled in device tree through ``snps,tso`` entry.
+
+Energy Efficient Ethernet
+-------------------------
+
+Energy Efficient Ethernet (EEE) enables IEEE 802.3 MAC sublayer along with a
+family of Physical layer to operate in the Low Power Idle (LPI) mode. The EEE
+mode supports the IEEE 802.3 MAC operation at 100Mbps, 1000Mbps and 1Gbps.
+
+The LPI mode allows power saving by switching off parts of the communication
+device functionality when there is no data to be transmitted & received.
+The system on both the side of the link can disable some functionalities and
+save power during the period of low-link utilization. The MAC controls whether
+the system should enter or exit the LPI mode and communicate this to PHY.
+
+As soon as the interface is opened, the driver verifies if the EEE can be
+supported. This is done by looking at both the DMA HW capability register and
+the PHY devices MCD registers.
+
+To enter in TX LPI mode the driver needs to have a software timer that enable
+and disable the LPI mode when there is nothing to be transmitted.
+
+Precision Time Protocol (PTP)
+-----------------------------
+
+The driver supports the IEEE 1588-2002, Precision Time Protocol (PTP), which
+enables precise synchronization of clocks in measurement and control systems
+implemented with technologies such as network communication.
+
+In addition to the basic timestamp features mentioned in IEEE 1588-2002
+Timestamps, new GMAC cores support the advanced timestamp features.
+IEEE 1588-2008 can be enabled when configuring the Kernel.
+
+SGMII/RGMII Support
+-------------------
+
+New GMAC devices provide own way to manage RGMII/SGMII. This information is
+available at run-time by looking at the HW capability register. This means
+that the stmmac can manage auto-negotiation and link status w/o using the
+PHYLIB stuff. In fact, the HW provides a subset of extended registers to
+restart the ANE, verify Full/Half duplex mode and Speed. Thanks to these
+registers, it is possible to look at the Auto-negotiated Link Parter Ability.
+
+Physical
+--------
+
+The driver is compatible with Physical Abstraction Layer to be connected with
+PHY and GPHY devices.
+
+Platform Information
+--------------------
+
+Several information can be passed through the platform and device-tree.
+
+::
+
+    struct plat_stmmacenet_data {
+
+1) Bus identifier::
+
+        int bus_id;
+
+2) PHY Physical Address. If set to -1 the driver will pick the first PHY it
+finds::
+
+        int phy_addr;
+
+3) PHY Device Interface::
+
+        int interface;
+
+4) Specific platform fields for the MDIO bus::
+
+        struct stmmac_mdio_bus_data *mdio_bus_data;
+
+5) Internal DMA parameters::
+
+        struct stmmac_dma_cfg *dma_cfg;
+
+6) Fixed CSR Clock Range selection::
+
+        int clk_csr;
+
+7) HW uses the GMAC core::
+
+        int has_gmac;
+
+8) If set the MAC will use Enhanced Descriptors::
+
+        int enh_desc;
+
+9) Core is able to perform TX Checksum and/or RX Checksum in HW::
+
+        int tx_coe;
+        int rx_coe;
+
+11) Some HWs are not able to perform the csum in HW for over-sized frames due
+to limited buffer sizes. Setting this flag the csum will be done in SW on
+JUMBO frames::
+
+        int bugged_jumbo;
+
+12) Core has the embedded power module::
+
+        int pmt;
+
+13) Force DMA to use the Store and Forward mode or Threshold mode::
+
+        int force_sf_dma_mode;
+        int force_thresh_dma_mode;
+
+15) Force to disable the RX Watchdog feature and switch to NAPI mode::
+
+        int riwt_off;
+
+16) Limit the maximum operating speed and MTU::
+
+        int max_speed;
+        int maxmtu;
+
+18) Number of Multicast/Unicast filters::
+
+        int multicast_filter_bins;
+        int unicast_filter_entries;
+
+20) Limit the maximum TX and RX FIFO size::
+
+        int tx_fifo_size;
+        int rx_fifo_size;
+
+21) Use the specified number of TX and RX Queues::
+
+        u32 rx_queues_to_use;
+        u32 tx_queues_to_use;
+
+22) Use the specified TX and RX scheduling algorithm::
+
+        u8 rx_sched_algorithm;

+
+23) Internal TX and RX Queue parameters::
+
+        struct stmmac_rxq_cfg rx_queues_cfg[MTL_MAX_RX_QUEUES];
+        struct stmmac_txq_cfg tx_queues_cfg[MTL_MAX_TX_QUEUES];
+
+24) This callback is used for modifying some syscfg registers (on ST SoCs)
+according to the link speed negotiated by the physical layer::
+
+        void (*fix_mac_speed)(void *priv, unsigned int speed);
+
+25) Callbacks used for calling a custom initialization; This is sometimes
+necessary on some platforms (e.g. ST boxes) where the HW needs to have set
+some PIO lines or system cfg registers. init/exit callbacks should not use
+or modify platform data::
+
+        int (*init)(struct platform_device *pdev, void *priv);
+        void (*exit)(struct platform_device *pdev, void *priv);
+
+26) Perform HW setup of the bus. For example, on some ST platforms this field
+is used to configure the AMBA bridge to generate more efficient STBus traffic::
+
+        struct mac_device_info *(*setup)(void *priv);
+        void *bsp_priv;
+
+27) Internal clocks and rates::

+
+3) Enable 8xPBL::
+

+Device Tree Information
+-----------------------
+
+Please refer to the following document:
+Documentation/devicetree/bindings/net/snps,dwmac.yaml
+
+HW Capabilities
+---------------
+
+Note that, starting from new chips, where it is available the HW capability
+register, many configurations are discovered at run-time for example to
+understand if EEE, HW csum, PTP, enhanced descriptor etc are actually
+available. As strategy adopted in this driver, the information from the HW
+capability register can replace what has been passed from the platform.
+
+Debug Information
+=================
+
+The driver exports many information i.e. internal statistics, debug
+information, MAC and DMA registers etc.
+
+These can be read in several ways depending on the type of the information
+actually needed.
+
+For example a user can be use the ethtool support to get statistics: e.g.
+using: ``ethtool -S ethX`` (that shows the Management counters (MMC) if
+supported) or sees the MAC/DMA registers: e.g. using: ``ethtool -d ethX``
+
+Compiling the Kernel with ``CONFIG_DEBUG_FS`` the driver will export the
+following debugfs entries:
+
+ - ``descriptors_status``: To show the DMA TX/RX descriptor rings
+ - ``dma_cap``: To show the HW Capabilities
+
+Developer can also use the ``debug`` module parameter to get further debug
+information (please see: NETIF Msg Level).
+
+Support
+=======
+
+If an issue is identified with the released source code on a supported kernel
+with a supported adapter, email the specific information related to the
+issue to netdev@vger.kernel.org

+Texas Instruments CPSW ethernet driver
+======================================
+
+Multiqueue & CBS & MQPRIO
+=========================
+
+
+The cpsw has 3 CBS shapers for each external ports. This document
+describes MQPRIO and CBS Qdisc offload configuration for cpsw driver
+based on examples. It potentially can be used in audio video bridging
+(AVB) and time sensitive networking (TSN).
+
+The following examples were tested on AM572x EVM and BBB boards.
+
+Test setup
+==========
+
+Under consideration two examples with AM572x EVM running cpsw driver
+in dual_emac mode.
+
+Several prerequisites:
+
+- TX queues must be rated starting from txq0 that has highest priority
+- Traffic classes are used starting from 0, that has highest priority
+- CBS shapers should be used with rated queues
+- The bandwidth for CBS shapers has to be set a little bit more then
+  potential incoming rate, thus, rate of all incoming tx queues has
+  to be a little less
+- Real rates can differ, due to discreetness
+- Map skb-priority to txq is not enough, also skb-priority to l2 prio
+  map has to be created with ip or vconfig tool
+- Any l2/socket prio (0 - 7) for classes can be used, but for
+  simplicity default values are used: 3 and 2
+- only 2 classes tested: A and B, but checked and can work with more,
+  maximum allowed 4, but only for 3 rate can be set.
+
+Test setup for examples

+
+Port renaming
+=============
+
+On older udev versions renaming of ethX to swXpY will not be automatically
+supported
+
+In order to rename via udev::
+
+    ip -d link show dev sw0p1 | grep switchid
+
+    SUBSYSTEM=="net", ACTION=="add", ATTR{phys_switch_id}==<switchid>, \
+	    ATTR{phys_port_name}!="", NAME="sw0$attr{phys_port_name}"
+
+
+Dual mac mode
+=============
+
+- The new (cpsw_new.c) driver is operating in dual-emac mode by default, thus
+  working as 2 individual network interfaces. Main differences from legacy CPSW
+  driver are:
+
+ - optimized promiscuous mode: The P0_UNI_FLOOD (both ports) is enabled in
+   addition to ALLMULTI (current port) instead of ALE_BYPASS.
+   So, Ports in promiscuous mode will keep possibility of mcast and vlan
+   filtering, which is provides significant benefits when ports are joined
+   to the same bridge, but without enabling "switch" mode, or to different
+   bridges.
+ - learning disabled on ports as it make not too much sense for
+   segregated ports - no forwarding in HW.
+ - enabled basic support for devlink.

+================================

+
+Bridging in dual mac mode
+=========================
+
+The dual_mac mode requires two vids to be reserved for internal purposes,
+which, by default, equal CPSW Port numbers. As result, bridge has to be
+configured in vlan unaware mode or default_pvid has to be adjusted::
+
+	ip link add name br0 type bridge
+	ip link set dev br0 type bridge vlan_filtering 0
+	echo 0 > /sys/class/net/br0/bridge/default_pvid
+	ip link set dev sw0p1 master br0
+	ip link set dev sw0p2 master br0
+
+or::
+
+	ip link add name br0 type bridge
+	ip link set dev br0 type bridge vlan_filtering 0
+	echo 100 > /sys/class/net/br0/bridge/default_pvid
+	ip link set dev br0 type bridge vlan_filtering 1
+	ip link set dev sw0p1 master br0
+	ip link set dev sw0p2 master br0
+
+Enabling "switch"
+=================
+
+The Switch mode can be enabled by configuring devlink driver parameter
+"switch_mode" to 1/true::
+
+	devlink dev param set platform/48484000.switch \
+	name switch_mode value 1 cmode runtime
+
+This can be done regardless of the state of Port's netdev devices - UP/DOWN, but
+Port's netdev devices have to be in UP before joining to the bridge to avoid
+overwriting of bridge configuration as CPSW switch driver copletly reloads its
+configuration when first Port changes its state to UP.
+
+When the both interfaces joined the bridge - CPSW switch driver will enable
+marking packets with offload_fwd_mark flag unless "ale_bypass=0"
+
+All configuration is implemented via switchdev API.
+
+Bridge setup
+============
+
+::
+
+	devlink dev param set platform/48484000.switch \
+	name switch_mode value 1 cmode runtime
+
+	ip link add name br0 type bridge
+	ip link set dev br0 type bridge ageing_time 1000
+	ip link set dev sw0p1 up
+	ip link set dev sw0p2 up
+	ip link set dev sw0p1 master br0
+	ip link set dev sw0p2 master br0
+
+	[*] bridge vlan add dev br0 vid 1 pvid untagged self
+
+	[*] if vlan_filtering=1. where default_pvid=1
+
+	Note. Steps [*] are mandatory.
+
+
+On/off STP
+==========
+
+::
+
+	ip link set dev BRDEV type bridge stp_state 1/0
+
+VLAN configuration
+==================
+
+::
+
+  bridge vlan add dev br0 vid 1 pvid untagged self <---- add cpu port to VLAN 1
+
+Note. This step is mandatory for bridge/default_pvid.
+
+Add extra VLANs
+===============
+
+ 1. untagged::
+
+	bridge vlan add dev sw0p1 vid 100 pvid untagged master
+	bridge vlan add dev sw0p2 vid 100 pvid untagged master

+
+    Only PCI devices will work with this driver.
+
+    Supported:

+    108d	0014		Olicom OC-2326
+    =========	=========	===========================================
+
+
+    Caveats:
+
+    I am not sure if 100BaseTX daughterboards (for those cards which
+    support such things) will work.  I haven't had any solid evidence
+    either way.
+
+    However, if a card supports 100BaseTx without requiring an add
+    on daughterboard, it should work with 100BaseTx.
+
+    The "Netelligent 10 T/2 PCI UTP/Coax" (b012) device is untested,
+    but I do not expect any problems.
+
+
+II. Driver Options
+==================
+
+	1. You can append debug=x to the end of the insmod line to get
+	   debug messages, where x is a bit field where the bits mean
+	   the following:
+
+	   ====		=====================================
+	   0x01		Turn on general debugging messages.
+	   0x02		Turn on receive debugging messages.
+	   0x04		Turn on transmit debugging messages.
+	   0x08		Turn on list debugging messages.
+	   ====		=====================================
+
+	2. You can append aui=1 to the end of the insmod line to cause
+	   the adapter to use the AUI interface instead of the 10 Base T
+	   interface.  This is also what to do if you want to use the BNC
+	   connector on a TLAN based device.  (Setting this option on a
+	   device that does not have an AUI/BNC connector will probably
+	   cause it to not function correctly.)
+
+	3. You can set duplex=1 to force half duplex, and duplex=2 to
+	   force full duplex.
+
+	4. You can set speed=10 to force 10Mbs operation, and speed=100
+	   to force 100Mbs operation. (I'm not sure what will happen
+	   if a card which only supports 10Mbs is forced into 100Mbs
+	   mode.)
+
+	5. You have to use speed=X duplex=Y together now. If you just
+	   do "insmod tlan.o speed=100" the driver will do Auto-Neg.
+	   To force a 10Mbps Half-Duplex link do "insmod tlan.o speed=10
+	   duplex=1".
+
+	6. If the driver is built into the kernel, you can use the 3rd
+	   and 4th parameters to set aui and debug respectively.  For
+	   example::
+
+		ether=0,0,0x1,0x7,eth0
+
+	   This sets aui to 0x1 and debug to 0x7, assuming eth0 is a
+	   supported TLAN device.
+
+	   The bits in the third byte are assigned as follows:
+
+		====   ===============
+		0x01   aui
+		0x02   use half duplex
+		0x04   use full duplex
+		0x08   use 10BaseT
+		0x10   use 100BaseTx
+		====   ===============
+
+	   You also need to set both speed and duplex settings when forcing
+	   speeds with kernel-parameters.
+	   ether=0,0,0x12,0,eth0 will force link to 100Mbps Half-Duplex.
+
+	7. If you have more than one tlan adapter in your system, you can
+	   use the above options on a per adapter basis. To force a 100Mbit/HD
+	   link with your eth1 adapter use::
+
+		insmod tlan speed=0,100 duplex=0,1
+
+	   Now eth0 will use auto-neg and eth1 will be forced to 100Mbit/HD.
+	   Note that the tlan driver supports a maximum of 8 adapters.
+
+
+III. Things to try if you have problems
+=======================================
+
+	1. Make sure your card's PCI id is among those listed in
+	   section I, above.
+	2. Make sure routing is correct.
+	3. Try forcing different speed/duplex settings
+
+
+There is also a tlan mailing list which you can join by sending "subscribe tlan"
+in the body of an email to majordomo@vuser.vu.union.edu.
+
+There is also a tlan website at http://www.compaq.com

+===========================
+The Spidernet Device Driver
+===========================
+
+Written by Linas Vepstas <linas@austin.ibm.com>
+
+Version of 7 June 2007
+
+Abstract
+========
+This document sketches the structure of portions of the spidernet
+device driver in the Linux kernel tree. The spidernet is a gigabit
+ethernet device built into the Toshiba southbridge commonly used
+in the SONY Playstation 3 and the IBM QS20 Cell blade.
+
+The Structure of the RX Ring.
+=============================
+The receive (RX) ring is a circular linked list of RX descriptors,
+together with three pointers into the ring that are used to manage its
+contents.
+
+The elements of the ring are called "descriptors" or "descrs"; they
+describe the received data. This includes a pointer to a buffer
+containing the received data, the buffer size, and various status bits.
+
+There are three primary states that a descriptor can be in: "empty",
+"full" and "not-in-use".  An "empty" or "ready" descriptor is ready
+to receive data from the hardware. A "full" descriptor has data in it,
+and is waiting to be emptied and processed by the OS. A "not-in-use"
+descriptor is neither empty or full; it is simply not ready. It may
+not even have a data buffer in it, or is otherwise unusable.
+
+During normal operation, on device startup, the OS (specifically, the
+spidernet device driver) allocates a set of RX descriptors and RX
+buffers. These are all marked "empty", ready to receive data. This
+ring is handed off to the hardware, which sequentially fills in the
+buffers, and marks them "full". The OS follows up, taking the full
+buffers, processing them, and re-marking them empty.
+
+This filling and emptying is managed by three pointers, the "head"
+and "tail" pointers, managed by the OS, and a hardware current
+descriptor pointer (GDACTDPA). The GDACTDPA points at the descr
+currently being filled. When this descr is filled, the hardware
+marks it full, and advances the GDACTDPA by one.  Thus, when there is
+flowing RX traffic, every descr behind it should be marked "full",
+and everything in front of it should be "empty".  If the hardware
+discovers that the current descr is not empty, it will signal an
+interrupt, and halt processing.
+
+The tail pointer tails or trails the hardware pointer. When the
+hardware is ahead, the tail pointer will be pointing at a "full"
+descr. The OS will process this descr, and then mark it "not-in-use",
+and advance the tail pointer.  Thus, when there is flowing RX traffic,
+all of the descrs in front of the tail pointer should be "full", and
+all of those behind it should be "not-in-use". When RX traffic is not
+flowing, then the tail pointer can catch up to the hardware pointer.
+The OS will then note that the current tail is "empty", and halt
+processing.
+
+The head pointer (somewhat mis-named) follows after the tail pointer.
+When traffic is flowing, then the head pointer will be pointing at
+a "not-in-use" descr. The OS will perform various housekeeping duties
+on this descr. This includes allocating a new data buffer and
+dma-mapping it so as to make it visible to the hardware. The OS will
+then mark the descr as "empty", ready to receive data. Thus, when there
+is flowing RX traffic, everything in front of the head pointer should
+be "not-in-use", and everything behind it should be "empty". If no
+RX traffic is flowing, then the head pointer can catch up to the tail
+pointer, at which point the OS will notice that the head descr is
+"empty", and it will halt processing.
+
+Thus, in an idle system, the GDACTDPA, tail and head pointers will
+all be pointing at the same descr, which should be "empty". All of the
+other descrs in the ring should be "empty" as well.
+
+The show_rx_chain() routine will print out the locations of the
+GDACTDPA, tail and head pointers. It will also summarize the contents
+of the ring, starting at the tail pointer, and listing the status
+of the descrs that follow.
+
+A typical example of the output, for a nearly idle system, might be::
+
+    net eth1: Total number of descrs=256
+    net eth1: Chain tail located at descr=20
+    net eth1: Chain head is at 20
+    net eth1: HW curr desc (GDACTDPA) is at 21
+    net eth1: Have 1 descrs with stat=x40800101
+    net eth1: HW next desc (GDACNEXTDA) is at 22
+    net eth1: Last 255 descrs with stat=xa0800000
+
+In the above, the hardware has filled in one descr, number 20. Both
+head and tail are pointing at 20, because it has not yet been emptied.
+Meanwhile, hw is pointing at 21, which is free.
+
+The "Have nnn decrs" refers to the descr starting at the tail: in this
+case, nnn=1 descr, starting at descr 20. The "Last nnn descrs" refers
+to all of the rest of the descrs, from the last status change. The "nnn"
+is a count of how many descrs have exactly the same status.
+
+The status x4... corresponds to "full" and status xa... corresponds
+to "empty". The actual value printed is RXCOMST_A.
+
+In the device driver source code, a different set of names are
+used for these same concepts, so that::
+
+    "empty" == SPIDER_NET_DESCR_CARDOWNED == 0xa
+    "full"  == SPIDER_NET_DESCR_FRAME_END == 0x4
+    "not in use" == SPIDER_NET_DESCR_NOT_IN_USE == 0xf
+
+
+The RX RAM full bug/feature
+===========================
+
+As long as the OS can empty out the RX buffers at a rate faster than
+the hardware can fill them, there is no problem. If, for some reason,
+the OS fails to empty the RX ring fast enough, the hardware GDACTDPA
+pointer will catch up to the head, notice the not-empty condition,
+ad stop. However, RX packets may still continue arriving on the wire.
+The spidernet chip can save some limited number of these in local RAM.
+When this local ram fills up, the spider chip will issue an interrupt
+indicating this (GHIINT0STS will show ERRINT, and the GRMFLLINT bit
+will be set in GHIINT1STS).  When the RX ram full condition occurs,
+a certain bug/feature is triggered that has to be specially handled.
+This section describes the special handling for this condition.
+
+When the OS finally has a chance to run, it will empty out the RX ring.
+In particular, it will clear the descriptor on which the hardware had
+stopped. However, once the hardware has decided that a certain
+descriptor is invalid, it will not restart at that descriptor; instead
+it will restart at the next descr. This potentially will lead to a
+deadlock condition, as the tail pointer will be pointing at this descr,
+which, from the OS point of view, is empty; the OS will be waiting for
+this descr to be filled. However, the hardware has skipped this descr,
+and is filling the next descrs. Since the OS doesn't see this, there
+is a potential deadlock, with the OS waiting for one descr to fill,
+while the hardware is waiting for a different set of descrs to become
+empty.
+
+A call to show_rx_chain() at this point indicates the nature of the
+problem. A typical print when the network is hung shows the following::
+
+    net eth1: Spider RX RAM full, incoming packets might be discarded!
+    net eth1: Total number of descrs=256
+    net eth1: Chain tail located at descr=255
+    net eth1: Chain head is at 255
+    net eth1: HW curr desc (GDACTDPA) is at 0
+    net eth1: Have 1 descrs with stat=xa0800000
+    net eth1: HW next desc (GDACNEXTDA) is at 1
+    net eth1: Have 127 descrs with stat=x40800101
+    net eth1: Have 1 descrs with stat=x40800001
+    net eth1: Have 126 descrs with stat=x40800101
+    net eth1: Last 1 descrs with stat=xa0800000
+
+Both the tail and head pointers are pointing at descr 255, which is
+marked xa... which is "empty". Thus, from the OS point of view, there
+is nothing to be done. In particular, there is the implicit assumption
+that everything in front of the "empty" descr must surely also be empty,
+as explained in the last section. The OS is waiting for descr 255 to
+become non-empty, which, in this case, will never happen.
+
+The HW pointer is at descr 0. This descr is marked 0x4.. or "full".
+Since its already full, the hardware can do nothing more, and thus has
+halted processing. Notice that descrs 0 through 254 are all marked
+"full", while descr 254 and 255 are empty. (The "Last 1 descrs" is
+descr 254, since tail was at 255.) Thus, the system is deadlocked,
+and there can be no forward progress; the OS thinks there's nothing
+to do, and the hardware has nowhere to put incoming data.
+
+This bug/feature is worked around with the spider_net_resync_head_ptr()
+routine. When the driver receives RX interrupts, but an examination
+of the RX chain seems to show it is empty, then it is probable that
+the hardware has skipped a descr or two (sometimes dozens under heavy
+network conditions). The spider_net_resync_head_ptr() subroutine will
+search the ring for the next full descr, and the driver will resume
+operations there.  Since this will leave "holes" in the ring, there
+is also a spider_net_resync_tail_ptr() that will skip over such holes.
+
+As of this writing, the spider_net_resync() strategy seems to work very
+well, even under heavy network loads.
+
+
+The TX ring
+===========
+The TX ring uses a low-watermark interrupt scheme to make sure that
+the TX queue is appropriately serviced for large packet sizes.
+
+For packet sizes greater than about 1KBytes, the kernel can fill
+the TX ring quicker than the device can drain it. Once the ring
+is full, the netdev is stopped. When there is room in the ring,
+the netdev needs to be reawakened, so that more TX packets are placed
+in the ring. The hardware can empty the ring about four times per jiffy,
+so its not appropriate to wait for the poll routine to refill, since
+the poll routine runs only once per jiffy.  The low-watermark mechanism
+marks a descr about 1/4th of the way from the bottom of the queue, so
+that an interrupt is generated when the descr is processed. This
+interrupt wakes up the netdev, which can then refill the queue.
+For large packets, this mechanism generates a relatively small number
+of interrupts, about 1K/sec. For smaller packets, this will drop to zero
+interrupts, as the hardware can empty the queue faster than the kernel
+can fill it.

-generations of SoCs, both on PowerPC and ARM64.
-
-The Freescale DPAA architecture consists of a series of hardware blocks
-that support Ethernet connectivity. The Ethernet driver depends upon the
-following drivers in the Linux kernel:

- - Peripheral Access Memory Unit (PAMU) (* needed only for PPC platforms)
-    drivers/iommu/fsl_*
- - Frame Manager (FMan)
-    drivers/net/ethernet/freescale/fman

-DPAA Ethernet Frame Processing
-==============================
-
-On Rx, buffers for the incoming frames are retrieved from the buffers found
-in the dedicated interface buffer pool. The driver initializes and seeds these
-with one page buffers.
-
-On Tx, all transmitted frames are returned to the driver through Tx
-confirmation frame queues. The driver is then responsible for freeing the
-buffers. In order to do this properly, a backpointer is added to the buffer
-before transmission that points to the skb. When the buffer returns to the
-driver on a confirmation FQ, the skb can be correctly consumed.
-
-DPAA Ethernet Features
-======================
-
-Currently the DPAA Ethernet driver enables the basic features required for
-a Linux Ethernet driver. The support for advanced features will be added
-gradually.
-
-The driver has Rx and Tx checksum offloading for UDP and TCP. Currently the Rx
-checksum offload feature is enabled by default and cannot be controlled through
-ethtool. Also, rx-flow-hash and rx-hashing was added. The addition of RSS
-provides a big performance boost for the forwarding scenarios, allowing
-different traffic flows received by one interface to be processed by different
-CPUs in parallel.
-
-The driver has support for multiple prioritized Tx traffic classes. Priorities
-range from 0 (lowest) to 3 (highest). These are mapped to HW workqueues with
-strict priority levels. Each traffic class contains NR_CPU TX queues. By
-default, only one traffic class is enabled and the lowest priority Tx queues
-are used. Higher priority traffic classes can be enabled with the mqprio
-qdisc. For example, all four traffic classes are enabled on an interface with
-the following command. Furthermore, skb priority levels are mapped to traffic
-classes as follows:
-
-	* priorities 0 to 3 - traffic class 0 (low priority)
-	* priorities 4 to 7 - traffic class 1 (medium-low priority)
-	* priorities 8 to 11 - traffic class 2 (medium-high priority)
-	* priorities 12 to 15 - traffic class 3 (high priority)
-
-::
-
-  tc qdisc add dev <int> root handle 1: \
-	 mqprio num_tc 4 map 0 0 0 0 1 1 1 1 2 2 2 2 3 3 3 3 hw 1
-
-DPAA IRQ Affinity and Receive Side Scaling
-==========================================
-
-Traffic coming on the DPAA Rx queues or on the DPAA Tx confirmation
-queues is seen by the CPU as ingress traffic on a certain portal.
-The DPAA QMan portal interrupts are affined each to a certain CPU.
-The same portal interrupt services all the QMan portal consumers.
-
-By default the DPAA Ethernet driver enables RSS, making use of the
-DPAA FMan Parser and Keygen blocks to distribute traffic on 128
-hardware frame queues using a hash on IP v4/v6 source and destination
-and L4 source and destination ports, in present in the received frame.
-When RSS is disabled, all traffic received by a certain interface is
-received on the default Rx frame queue. The default DPAA Rx frame
-queues are configured to put the received traffic into a pool channel
-that allows any available CPU portal to dequeue the ingress traffic.
-The default frame queues have the HOLDACTIVE option set, ensuring that
-traffic bursts from a certain queue are serviced by the same CPU.
-This ensures a very low rate of frame reordering. A drawback of this
-is that only one CPU at a time can service the traffic received by a
-certain interface when RSS is not enabled.
-
-To implement RSS, the DPAA Ethernet driver allocates an extra set of
-128 Rx frame queues that are configured to dedicated channels, in a
-round-robin manner. The mapping of the frame queues to CPUs is now
-hardcoded, there is no indirection table to move traffic for a certain
-FQ (hash result) to another CPU. The ingress traffic arriving on one
-of these frame queues will arrive at the same portal and will always
-be processed by the same CPU. This ensures intra-flow order preservation
-and workload distribution for multiple traffic flows.
-
-RSS can be turned off for a certain interface using ethtool, i.e.::
-
-	# ethtool -N fm1-mac9 rx-flow-hash tcp4 ""
-
-To turn it back on, one needs to set rx-flow-hash for tcp4/6 or udp4/6::
-
-	# ethtool -N fm1-mac9 rx-flow-hash udp4 sfdn
-
-There is no independent control for individual protocols, any command
-run for one of tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 is
-going to control the rx-flow-hashing for all protocols on that interface.
-
-Besides using the FMan Keygen computed hash for spreading traffic on the
-128 Rx FQs, the DPAA Ethernet driver also sets the skb hash value when
-the NETIF_F_RXHASH feature is on (active by default). This can be turned
-on or off through ethtool, i.e.::
-
-	# ethtool -K fm1-mac9 rx-hashing off
-	# ethtool -k fm1-mac9 | grep hash
-	receive-hashing: off
-	# ethtool -K fm1-mac9 rx-hashing on
-	Actual changes:
-	receive-hashing: on
-	# ethtool -k fm1-mac9 | grep hash
-	receive-hashing: on
-
-Please note that Rx hashing depends upon the rx-flow-hashing being on
-for that interface - turning off rx-flow-hashing will also disable the
-rx-hashing (without ethtool reporting it as off as that depends on the
-NETIF_F_RXHASH feature flag).
-
-Debugging
-=========
-
-The following statistics are exported for each interface through ethtool:
-
-	- interrupt count per CPU
-	- Rx packets count per CPU
-	- Tx packets count per CPU
-	- Tx confirmed packets count per CPU
-	- Tx S/G frames count per CPU
-	- Tx error count per CPU
-	- Rx error count per CPU
-	- Rx error count per type
-	- congestion related statistics:
-
-		- congestion status
-		- time spent in congestion
-		- number of time the device entered congestion
-		- dropped packets count per cause
-
-The driver also exports the following information in sysfs:
-
-	- the FQ IDs for each FQ type
-	  /sys/devices/platform/soc/<addr>.fman/<addr>.ethernet/dpaa-ethernet.<id>/net/fm<nr>-mac<nr>/fqids
-
-	- the ID of the buffer pool in use
-	  /sys/devices/platform/soc/<addr>.fman/<addr>.ethernet/dpaa-ethernet.<id>/net/fm<nr>-mac<nr>/bpids

-DPAA2 DPIO (Data Path I/O) Overview
-===================================
-

-
-This document provides an overview of the Freescale DPAA2 DPIO
-drivers
-
-Introduction
-============
-
-A DPAA2 DPIO (Data Path I/O) is a hardware object that provides
-interfaces to enqueue and dequeue frames to/from network interfaces
-and other accelerators.  A DPIO also provides hardware buffer
-pool management for network interfaces.
-
-This document provides an overview the Linux DPIO driver, its
-subcomponents, and its APIs.
-
-See Documentation/networking/device_drivers/freescale/dpaa2/overview.rst for
-a general overview of DPAA2 and the general DPAA2 driver architecture in Linux.
-
-Driver Overview
----------------
-
-The DPIO driver is bound to DPIO objects discovered on the fsl-mc bus and
-provides services that:
-
-  A. allow other drivers, such as the Ethernet driver, to enqueue and dequeue
-     frames for their respective objects
-  B. allow drivers to register callbacks for data availability notifications
-     when data becomes available on a queue or channel
-  C. allow drivers to manage hardware buffer pools
-
-The Linux DPIO driver consists of 3 primary components--
-   DPIO object driver-- fsl-mc driver that manages the DPIO object
-
-   DPIO service-- provides APIs to other Linux drivers for services
-
-   QBman portal interface-- sends portal commands, gets responses::

-
-
-DPIO Object Driver (dpio-driver.c)
-----------------------------------
-
-   The dpio-driver component registers with the fsl-mc bus to handle objects of
-   type "dpio".  The implementation of probe() handles basic initialization
-   of the DPIO including mapping of the DPIO regions (the QBman SW portal)
-   and initializing interrupts and registering irq handlers.  The dpio-driver
-   registers the probed DPIO with dpio-service.
-
-DPIO service  (dpio-service.c, dpaa2-io.h)
-------------------------------------------
-
-   The dpio service component provides queuing, notification, and buffers
-   management services to DPAA2 drivers, such as the Ethernet driver.  A system
-   will typically allocate 1 DPIO object per CPU to allow queuing operations
-   to happen simultaneously across all CPUs.
-
-   Notification handling
-      dpaa2_io_service_register()
-
-      dpaa2_io_service_deregister()
-
-      dpaa2_io_service_rearm()
-
-   Queuing
-      dpaa2_io_service_pull_fq()
-
-      dpaa2_io_service_pull_channel()
-
-      dpaa2_io_service_enqueue_fq()
-
-      dpaa2_io_service_enqueue_qd()
-
-      dpaa2_io_store_create()
-
-      dpaa2_io_store_destroy()
-
-      dpaa2_io_store_next()
-
-   Buffer pool management
-      dpaa2_io_service_release()
-
-      dpaa2_io_service_acquire()
-
-QBman portal interface (qbman-portal.c)
----------------------------------------
-
-   The qbman-portal component provides APIs to do the low level hardware
-   bit twiddling for operations such as:
-
-      - initializing Qman software portals
-      - building and sending portal commands
-      - portal interrupt configuration and processing
-
-   The qbman-portal APIs are not public to other drivers, and are
-   only used by dpio-service.
-
-Other (dpaa2-fd.h, dpaa2-global.h)
-----------------------------------
-
-   Frame descriptor and scatter-gather definitions and the APIs used to
-   manipulate them are defined in dpaa2-fd.h.
-
-   Dequeue result struct and parsing APIs are defined in dpaa2-global.h.

-DPAA2 Ethernet driver
-===============================
-
-:Copyright: |copy| 2017-2018 NXP
-
-This file provides documentation for the Freescale DPAA2 Ethernet driver.
-
-Supported Platforms
-===================
-This driver provides networking support for Freescale DPAA2 SoCs, e.g.
-LS2080A, LS2088A, LS1088A.
-
-
-Architecture Overview
-=====================
-Unlike regular NICs, in the DPAA2 architecture there is no single hardware block
-representing network interfaces; instead, several separate hardware resources
-concur to provide the networking functionality:
-
-- network interfaces
-- queues, channels
-- buffer pools
-- MAC/PHY
-
-All hardware resources are allocated and configured through the Management
-Complex (MC) portals. MC abstracts most of these resources as DPAA2 objects
-and exposes ABIs through which they can be configured and controlled. A few
-hardware resources, like queues, do not have a corresponding MC object and
-are treated as internal resources of other objects.
-
-For a more detailed description of the DPAA2 architecture and its object
-abstractions see *Documentation/networking/device_drivers/freescale/dpaa2/overview.rst*.
-
-Each Linux net device is built on top of a Datapath Network Interface (DPNI)
-object and uses Buffer Pools (DPBPs), I/O Portals (DPIOs) and Concentrators
-(DPCONs).

-                   =======================
-                                Channel
-
-Datapath I/O (DPIO) portals provide enqueue and dequeue services, data
-availability notifications and buffer pool management. DPIOs are shared between
-all DPAA2 objects (and implicitly all DPAA2 kernel drivers) that work with data
-frames, but must be affine to the CPUs for the purpose of traffic distribution.
-
-Frames are transmitted and received through hardware frame queues, which can be
-grouped in channels for the purpose of hardware scheduling. The Ethernet driver
-enqueues TX frames on egress queues and after transmission is complete a TX
-confirmation frame is sent back to the CPU.
-
-When frames are available on ingress queues, a data availability notification
-is sent to the CPU; notifications are raised per channel, so even if multiple
-queues in the same channel have available frames, only one notification is sent.
-After a channel fires a notification, is must be explicitly rearmed.
-
-Each network interface can have multiple Rx, Tx and confirmation queues affined
-to CPUs, and one channel (DPCON) for each CPU that services at least one queue.
-DPCONs are used to distribute ingress traffic to different CPUs via the cores'
-affine DPIOs.
-
-The role of hardware buffer pools is storage of ingress frame data. Each network
-interface has a privately owned buffer pool which it seeds with kernel allocated
-buffers.
-
-
-DPNIs are decoupled from PHYs; a DPNI can be connected to a PHY through a DPMAC
-object or to another DPNI through an internal link, but the connection is
-managed by MC and completely transparent to the Ethernet driver.

-Creating a Network Interface
-============================
-A net device is created for each DPNI object probed on the MC bus. Each DPNI has
-a number of properties which determine the network interface configuration
-options and associated hardware resources.
-
-DPNI objects (and the other DPAA2 objects needed for a network interface) can be
-added to a container on the MC bus in one of two ways: statically, through a
-Datapath Layout Binary file (DPL) that is parsed by MC at boot time; or created
-dynamically at runtime, via the DPAA2 objects APIs.
-
-
-Features & Offloads
-===================
-Hardware checksum offloading is supported for TCP and UDP over IPv4/6 frames.
-The checksum offloads can be independently configured on RX and TX through
-ethtool.
-
-Hardware offload of unicast and multicast MAC filtering is supported on the
-ingress path and permanently enabled.
-
-Scatter-gather frames are supported on both RX and TX paths. On TX, SG support
-is configurable via ethtool; on RX it is always enabled.
-
-The DPAA2 hardware can process jumbo Ethernet frames of up to 10K bytes.
-
-The Ethernet driver defines a static flow hashing scheme that distributes
-traffic based on a 5-tuple key: src IP, dst IP, IP proto, L4 src port,
-L4 dst port. No user configuration is supported for now.
-
-Hardware specific statistics for the network interface as well as some
-non-standard driver stats can be consulted through ethtool -S option.

-DPAA2 MAC / PHY support
-=======================
-

-
-Overview
---------
-
-The DPAA2 MAC / PHY support consists of a set of APIs that help DPAA2 network
-drivers (dpaa2-eth, dpaa2-ethsw) interract with the PHY library.
-
-DPAA2 Software Architecture
----------------------------
-
-Among other DPAA2 objects, the fsl-mc bus exports DPNI objects (abstracting a
-network interface) and DPMAC objects (abstracting a MAC). The dpaa2-eth driver
-probes on the DPNI object and connects to and configures a DPMAC object with
-the help of phylink.
-
-Data connections may be established between a DPNI and a DPMAC, or between two
-DPNIs. Depending on the connection type, the netif_carrier_[on/off] is handled
-directly by the dpaa2-eth driver or by phylink.

-           +--------------------------------------+
-
-
-Depending on an MC firmware configuration setting, each MAC may be in one of two modes:
-
-- DPMAC_LINK_TYPE_FIXED: the link state management is handled exclusively by
-  the MC firmware by polling the MAC PCS. Without the need to register a
-  phylink instance, the dpaa2-eth driver will not bind to the connected dpmac
-  object at all.
-
-- DPMAC_LINK_TYPE_PHY: The MC firmware is left waiting for link state update
-  events, but those are in fact passed strictly between the dpaa2-mac (based on
-  phylink) and its attached net_device driver (dpaa2-eth, dpaa2-ethsw),
-  effectively bypassing the firmware.
-
-Implementation
---------------
-
-At probe time or when a DPNI's endpoint is dynamically changed, the dpaa2-eth
-is responsible to find out if the peer object is a DPMAC and if this is the
-case, to integrate it with PHYLINK using the dpaa2_mac_connect() API, which
-will do the following:
-
- - look up the device tree for PHYLINK-compatible of binding (phy-handle)
- - will create a PHYLINK instance associated with the received net_device
- - connect to the PHY using phylink_of_phy_connect()
-
-The following phylink_mac_ops callback are implemented:
-
- - .validate() will populate the supported linkmodes with the MAC capabilities
-   only when the phy_interface_t is RGMII_* (at the moment, this is the only
-   link type supported by the driver).
-
- - .mac_config() will configure the MAC in the new configuration using the
-   dpmac_set_link_state() MC firmware API.
-
- - .mac_link_up() / .mac_link_down() will update the MAC link using the same
-   API described above.
-
-At driver unbind() or when the DPNI object is disconnected from the DPMAC, the
-dpaa2-eth driver calls dpaa2_mac_disconnect() which will, in turn, disconnect
-from the PHY and destroy the PHYLINK instance.
-
-In case of a DPNI-DPMAC connection, an 'ip link set dev eth0 up' would start
-the following sequence of operations:
-
-(1) phylink_start() called from .dev_open().
-(2) The .mac_config() and .mac_link_up() callbacks are called by PHYLINK.
-(3) In order to configure the HW MAC, the MC Firmware API
-    dpmac_set_link_state() is called.
-(4) The firmware will eventually setup the HW MAC in the new configuration.
-(5) A netif_carrier_on() call is made directly from PHYLINK on the associated
-    net_device.
-(6) The dpaa2-eth driver handles the LINK_STATE_CHANGE irq in order to
-    enable/disable Rx taildrop based on the pause frame settings.

-In case of a DPNI-DPNI connection, a usual sequence of operations looks like
-the following:
-
-(1) ip link set dev eth0 up
-(2) The dpni_enable() MC API called on the associated fsl_mc_device.
-(3) ip link set dev eth1 up
-(4) The dpni_enable() MC API called on the associated fsl_mc_device.
-(5) The LINK_STATE_CHANGED irq is received by both instances of the dpaa2-eth
-    driver because now the operational link state is up.
-(6) The netif_carrier_on() is called on the exported net_device from
-    link_state_update().

-
-
-Exported API
-------------
-
-Any DPAA2 driver that drivers endpoints of DPMAC objects should service its
-_EVENT_ENDPOINT_CHANGED irq and connect/disconnect from the associated DPMAC
-when necessary using the below listed API::
-
- - int dpaa2_mac_connect(struct dpaa2_mac *mac);
- - void dpaa2_mac_disconnect(struct dpaa2_mac *mac);
-
-A phylink integration is necessary only when the partner DPMAC is not of TYPE_FIXED.
-One can check for this condition using the below API::
-
- - bool dpaa2_mac_is_type_fixed(struct fsl_mc_device *dpmac_dev,struct fsl_mc_io *mc_io);
-
-Before connection to a MAC, the caller must allocate and populate the
-dpaa2_mac structure with the associated net_device, a pointer to the MC portal
-to be used and the actual fsl_mc_device structure of the DPMAC.

-DPAA2 (Data Path Acceleration Architecture Gen2) Overview
-=========================================================
-

-:Copyright: |copy| 2018 NXP
-
-This document provides an overview of the Freescale DPAA2 architecture
-and how it is integrated into the Linux kernel.
-
-Introduction
-============
-
-DPAA2 is a hardware architecture designed for high-speeed network
-packet processing.  DPAA2 consists of sophisticated mechanisms for
-processing Ethernet packets, queue management, buffer management,
-autonomous L2 switching, virtual Ethernet bridging, and accelerator
-(e.g. crypto) sharing.
-
-A DPAA2 hardware component called the Management Complex (or MC) manages the
-DPAA2 hardware resources.  The MC provides an object-based abstraction for
-software drivers to use the DPAA2 hardware.
-The MC uses DPAA2 hardware resources such as queues, buffer pools, and
-network ports to create functional objects/devices such as network
-interfaces, an L2 switch, or accelerator instances.
-The MC provides memory-mapped I/O command interfaces (MC portals)
-which DPAA2 software drivers use to operate on DPAA2 objects.
-
-The diagram below shows an overview of the DPAA2 resource management
-architecture::

-
-The MC mediates operations such as create, discover,
-connect, configuration, and destroy.  Fast-path operations
-on data, such as packet transmit/receive, are not mediated by
-the MC and are done directly using memory mapped regions in
-DPIO objects.
-
-Overview of DPAA2 Objects
-=========================
-
-The section provides a brief overview of some key DPAA2 objects.
-A simple scenario is described illustrating the objects involved
-in creating a network interfaces.
-
-DPRC (Datapath Resource Container)
-----------------------------------
-
-A DPRC is a container object that holds all the other
-types of DPAA2 objects.  In the example diagram below there
-are 8 objects of 5 types (DPMCP, DPIO, DPBP, DPNI, and DPMAC)
-in the container.
-
-::
-
-	+---------------------------------------------------------+
-	| DPRC                                                    |
-	|                                                         |
-	|  +-------+  +-------+  +-------+  +-------+  +-------+  |
-	|  | DPMCP |  | DPIO  |  | DPBP  |  | DPNI  |  | DPMAC |  |
-	|  +-------+  +-------+  +-------+  +---+---+  +---+---+  |
-	|  | DPMCP |  | DPIO  |                                   |
-	|  +-------+  +-------+                                   |
-	|  | DPMCP |                                              |
-	|  +-------+                                              |
-	|                                                         |
-	+---------------------------------------------------------+
-
-From the point of view of an OS, a DPRC behaves similar to a plug and
-play bus, like PCI.  DPRC commands can be used to enumerate the contents
-of the DPRC, discover the hardware objects present (including mappable
-regions and interrupts).
-
-::
-
-	DPRC.1 (bus)
-	   |
-	   +--+--------+-------+-------+-------+
-	      |        |       |       |       |
-	    DPMCP.1  DPIO.1  DPBP.1  DPNI.1  DPMAC.1
-	    DPMCP.2  DPIO.2
-	    DPMCP.3
-
-Hardware objects can be created and destroyed dynamically, providing
-the ability to hot plug/unplug objects in and out of the DPRC.
-
-A DPRC has a mappable MMIO region (an MC portal) that can be used
-to send MC commands.  It has an interrupt for status events (like
-hotplug).
-All objects in a container share the same hardware "isolation context".
-This means that with respect to an IOMMU the isolation granularity
-is at the DPRC (container) level, not at the individual object
-level.
-
-DPRCs can be defined statically and populated with objects
-via a config file passed to the MC when firmware starts it.
-
-DPAA2 Objects for an Ethernet Network Interface
------------------------------------------------
-
-A typical Ethernet NIC is monolithic-- the NIC device contains TX/RX
-queuing mechanisms, configuration mechanisms, buffer management,
-physical ports, and interrupts.  DPAA2 uses a more granular approach
-utilizing multiple hardware objects.  Each object provides specialized
-functions. Groups of these objects are used by software to provide
-Ethernet network interface functionality.  This approach provides
-efficient use of finite hardware resources, flexibility, and
-performance advantages.
-
-The diagram below shows the objects needed for a simple
-network interface configuration on a system with 2 CPUs.

-
-Below the objects are described.  For each object a brief description
-is provided along with a summary of the kinds of operations the object
-supports and a summary of key resources of the object (MMIO regions
-and IRQs).
-
-DPMAC (Datapath Ethernet MAC)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Represents an Ethernet MAC, a hardware device that connects to an Ethernet
-PHY and allows physical transmission and reception of Ethernet frames.
-
-- MMIO regions: none
-- IRQs: DPNI link change
-- commands: set link up/down, link config, get stats,
-  IRQ config, enable, reset
-
-DPNI (Datapath Network Interface)
-Contains TX/RX queues, network interface configuration, and RX buffer pool
-configuration mechanisms.  The TX/RX queues are in memory and are identified
-by queue number.
-
-- MMIO regions: none
-- IRQs: link state
-- commands: port config, offload config, queue config,
-  parse/classify config, IRQ config, enable, reset
-
-DPIO (Datapath I/O)
-~~~~~~~~~~~~~~~~~~~
-Provides interfaces to enqueue and dequeue
-packets and do hardware buffer pool management operations.  The DPAA2
-architecture separates the mechanism to access queues (the DPIO object)
-from the queues themselves.  The DPIO provides an MMIO interface to
-enqueue/dequeue packets.  To enqueue something a descriptor is written
-to the DPIO MMIO region, which includes the target queue number.
-There will typically be one DPIO assigned to each CPU.  This allows all
-CPUs to simultaneously perform enqueue/dequeued operations.  DPIOs are
-expected to be shared by different DPAA2 drivers.
-
-- MMIO regions: queue operations, buffer management
-- IRQs: data availability, congestion notification, buffer
-  pool depletion
-- commands: IRQ config, enable, reset
-
-DPBP (Datapath Buffer Pool)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Represents a hardware buffer pool.
-
-- MMIO regions: none
-- IRQs: none
-- commands: enable, reset
-
-DPMCP (Datapath MC Portal)
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-Provides an MC command portal.
-Used by drivers to send commands to the MC to manage
-objects.
-
-- MMIO regions: MC command portal
-- IRQs: command completion
-- commands: IRQ config, enable, reset
-
-Object Connections
-==================
-Some objects have explicit relationships that must
-be configured:
-
-- DPNI <--> DPMAC
-- DPNI <--> DPNI
-- DPNI <--> L2-switch-port
-
-    A DPNI must be connected to something such as a DPMAC,
-    another DPNI, or L2 switch port.  The DPNI connection
-    is made via a DPRC command.
-
-::
-
-              +-------+  +-------+
-              | DPNI  |  | DPMAC |
-              +---+---+  +---+---+
-                  |          |
-                  +==========+
-
-- DPNI <--> DPBP
-
-    A network interface requires a 'buffer pool' (DPBP
-    object) which provides a list of pointers to memory
-    where received Ethernet data is to be copied.  The
-    Ethernet driver configures the DPBPs associated with
-    the network interface.
-
-Interrupts
-==========
-All interrupts generated by DPAA2 objects are message
-interrupts.  At the hardware level message interrupts
-generated by devices will normally have 3 components--
-1) a non-spoofable 'device-id' expressed on the hardware
-bus, 2) an address, 3) a data value.
-
-In the case of DPAA2 devices/objects, all objects in the
-same container/DPRC share the same 'device-id'.
-For ARM-based SoC this is the same as the stream ID.
-
-
-DPAA2 Linux Drivers Overview
-============================
-
-This section provides an overview of the Linux kernel drivers for
-DPAA2-- 1) the bus driver and associated "DPAA2 infrastructure"
-drivers and 2) functional object drivers (such as Ethernet).
-
-As described previously, a DPRC is a container that holds the other
-types of DPAA2 objects.  It is functionally similar to a plug-and-play
-bus controller.
-Each object in the DPRC is a Linux "device" and is bound to a driver.
-The diagram below shows the Linux drivers involved in a networking
-scenario and the objects bound to each driver.  A brief description
-of each driver follows.

-	============================================|========================
-
-A brief description of each driver is provided below.
-
-MC-bus driver
--------------
-The MC-bus driver is a platform driver and is probed from a
-node in the device tree (compatible "fsl,qoriq-mc") passed in by boot
-firmware.  It is responsible for bootstrapping the DPAA2 kernel
-infrastructure.
-Key functions include:
-
-- registering a new bus type named "fsl-mc" with the kernel,
-  and implementing bus call-backs (e.g. match/uevent/dev_groups)
-- implementing APIs for DPAA2 driver registration and for device
-  add/remove
-- creates an MSI IRQ domain
-- doing a 'device add' to expose the 'root' DPRC, in turn triggering
-  a bind of the root DPRC to the DPRC driver
-
-The binding for the MC-bus device-tree node can be consulted at
-*Documentation/devicetree/bindings/misc/fsl,qoriq-mc.txt*.
-The sysfs bind/unbind interfaces for the MC-bus can be consulted at
-*Documentation/ABI/testing/sysfs-bus-fsl-mc*.
-
-DPRC driver
------------
-The DPRC driver is bound to DPRC objects and does runtime management
-of a bus instance.  It performs the initial bus scan of the DPRC
-and handles interrupts for container events such as hot plug by
-re-scanning the DPRC.
-
-Allocator
----------
-Certain objects such as DPMCP and DPBP are generic and fungible,
-and are intended to be used by other drivers.  For example,
-the DPAA2 Ethernet driver needs:
-
-- DPMCPs to send MC commands, to configure network interfaces
-- DPBPs for network buffer pools
-
-The allocator driver registers for these allocatable object types
-and those objects are bound to the allocator when the bus is probed.
-The allocator maintains a pool of objects that are available for
-allocation by other DPAA2 drivers.
-
-DPIO driver
------------
-The DPIO driver is bound to DPIO objects and provides services that allow
-other drivers such as the Ethernet driver to enqueue and dequeue data for
-their respective objects.
-Key services include:
-
-- data availability notifications
-- hardware queuing operations (enqueue and dequeue of data)
-- hardware buffer pool management
-
-To transmit a packet the Ethernet driver puts data on a queue and
-invokes a DPIO API.  For receive, the Ethernet driver registers
-a data availability notification callback.  To dequeue a packet
-a DPIO API is used.
-There is typically one DPIO object per physical CPU for optimum
-performance, allowing different CPUs to simultaneously enqueue
-and dequeue data.
-
-The DPIO driver operates on behalf of all DPAA2 drivers
-active in the kernel--  Ethernet, crypto, compression,
-etc.
-
-Ethernet driver
----------------
-The Ethernet driver is bound to a DPNI and implements the kernel
-interfaces needed to connect the DPAA2 network interface to
-the network stack.
-Each DPNI corresponds to a Linux network interface.
-
-MAC driver
-----------
-An Ethernet PHY is an off-chip, board specific component and is managed
-by the appropriate PHY driver via an mdio bus.  The MAC driver
-plays a role of being a proxy between the PHY driver and the
-MC.  It does this proxy via the MC commands to a DPMAC object.
-If the PHY driver signals a link change, the MAC driver notifies
-the MC via a DPMAC command.  If a network interface is brought
-up or down, the MC notifies the DPMAC driver via an interrupt and
-the driver can take appropriate action.

-===========================
-The Gianfar Ethernet Driver
-===========================
-
-:Author: Andy Fleming <afleming@freescale.com>
-:Updated: 2005-07-28
-
-
-Checksum Offloading
-===================
-
-The eTSEC controller (first included in parts from late 2005 like
-the 8548) has the ability to perform TCP, UDP, and IP checksums
-in hardware.  The Linux kernel only offloads the TCP and UDP
-checksums (and always performs the pseudo header checksums), so
-the driver only supports checksumming for TCP/IP and UDP/IP
-packets.  Use ethtool to enable or disable this feature for RX
-and TX.
-
-VLAN
-====
-
-In order to use VLAN, please consult Linux documentation on
-configuring VLANs.  The gianfar driver supports hardware insertion and
-extraction of VLAN headers, but not filtering.  Filtering will be
-done by the kernel.
-
-Multicasting
-============
-
-The gianfar driver supports using the group hash table on the
-TSEC (and the extended hash table on the eTSEC) for multicast
-filtering.  On the eTSEC, the exact-match MAC registers are used
-before the hash tables.  See Linux documentation on how to join
-multicast groups.
-
-Padding
-=======
-
-The gianfar driver supports padding received frames with 2 bytes
-to align the IP header to a 16-byte boundary, when supported by
-hardware.
-
-Ethtool
-=======
-
-The gianfar driver supports the use of ethtool for many
-configuration options.  You must run ethtool only on currently
-open interfaces.  See ethtool documentation for details.

-PCI Bars
-========
-The gVNIC PCI device exposes three 32-bit memory BARS:
-- Bar0 - Device configuration and status registers.
-- Bar1 - MSI-X vector table
-- Bar2 - IRQ, RX and TX doorbells
-
-Device Interactions
-===================
-The driver interacts with the device in the following ways:
- - Registers
-    - A block of MMIO registers
-    - See gve_register.h for more detail
- - Admin Queue
-    - See description below
- - Reset
-    - At any time the device can be reset
- - Interrupts
-    - See supported interrupts below
- - Transmit and Receive Queues
-    - See description below
-
-Registers
----------
-All registers are MMIO and big endian.
-
-The registers are used for initializing and configuring the device as well as
-querying device status in response to management interrupts.
-
-Admin Queue (AQ)
-----------------
-The Admin Queue is a PAGE_SIZE memory block, treated as an array of AQ
-commands, used by the driver to issue commands to the device and set up
-resources.The driver and the device maintain a count of how many commands
-have been submitted and executed. To issue AQ commands, the driver must do
-the following (with proper locking):
-
-1)  Copy new commands into next available slots in the AQ array
-2)  Increment its counter by he number of new commands
-3)  Write the counter into the GVE_ADMIN_QUEUE_DOORBELL register
-4)  Poll the ADMIN_QUEUE_EVENT_COUNTER register until it equals
-    the value written to the doorbell, or until a timeout.
-
-The device will update the status field in each AQ command reported as
-executed through the ADMIN_QUEUE_EVENT_COUNTER register.
-
-Device Resets
--------------
-A device reset is triggered by writing 0x0 to the AQ PFN register.
-This causes the device to release all resources allocated by the
-driver, including the AQ itself.
-
-Interrupts
-----------
-The following interrupts are supported by the driver:
-
-Management Interrupt
-~~~~~~~~~~~~~~~~~~~~
-The management interrupt is used by the device to tell the driver to
-look at the GVE_DEVICE_STATUS register.
-
-The handler for the management irq simply queues the service task in
-the workqueue to check the register and acks the irq.
-
-Notification Block Interrupts
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The notification block interrupts are used to tell the driver to poll
-the queues associated with that interrupt.
-
-The handler for these irqs schedule the napi for that block to run
-and poll the queues.
-
-Traffic Queues
---------------
-gVNIC's queues are composed of a descriptor ring and a buffer and are
-assigned to a notification block.
-
-The descriptor rings are power-of-two-sized ring buffers consisting of
-fixed-size descriptors. They advance their head pointer using a __be32
-doorbell located in Bar2. The tail pointers are advanced by consuming
-descriptors in-order and updating a __be32 counter. Both the doorbell
-and the counter overflow to zero.
-
-Each queue's buffers must be registered in advance with the device as a
-queue page list, and packet data can only be put in those pages.
-
-Transmit
-~~~~~~~~
-gve maps the buffers for transmit rings into a FIFO and copies the packets
-into the FIFO before sending them to the NIC.
-
-Receive
-~~~~~~~
-The buffers for receive rings are put into a data ring that is the same
-length as the descriptor ring and the head and tail pointers advance over
-the rings together.

-
-In This Release
-===============
-
-This file describes the Linux Base Driver for the Intel(R) PRO/100 Family of
-Adapters. This driver includes support for Itanium(R)2-based systems.
-
-For questions related to hardware requirements, refer to the documentation
-supplied with your Intel PRO/100 adapter.
-
-The following features are now available in supported kernels:
- - Native VLANs
- - Channel Bonding (teaming)
- - SNMP
-
-Channel Bonding documentation can be found in the Linux kernel source:
-/Documentation/networking/bonding.rst
-
-
-Identifying Your Adapter
-========================
-
-For information on how to identify your adapter, and for the latest Intel
-network drivers, refer to the Intel Support website:
-http://www.intel.com/support
-
-Driver Configuration Parameters
-===============================
-
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-Rx Descriptors:
-   Number of receive descriptors. A receive descriptor is a data
-   structure that describes a receive buffer and its attributes to the network
-   controller. The data in the descriptor is used by the controller to write
-   data from the controller to host memory. In the 3.x.x driver the valid range
-   for this parameter is 64-256. The default value is 256. This parameter can be
-   changed using the command::
-
-     ethtool -G eth? rx n
-
-   Where n is the number of desired Rx descriptors.
-
-Tx Descriptors:
-   Number of transmit descriptors. A transmit descriptor is a data
-   structure that describes a transmit buffer and its attributes to the network
-   controller. The data in the descriptor is used by the controller to read
-   data from the host memory to the controller. In the 3.x.x driver the valid
-   range for this parameter is 64-256. The default value is 128. This parameter
-   can be changed using the command::
-
-     ethtool -G eth? tx n
-
-   Where n is the number of desired Tx descriptors.
-
-Speed/Duplex:
-   The driver auto-negotiates the link speed and duplex settings by
-   default. The ethtool utility can be used as follows to force speed/duplex.::
-
-     ethtool -s eth?  autoneg off speed {10|100} duplex {full|half}
-
-   NOTE: setting the speed/duplex to incorrect values will cause the link to
-   fail.
-
-Event Log Message Level:
-   The driver uses the message level flag to log events
-   to syslog. The message level can be set at driver load time. It can also be
-   set using the command::
-
-     ethtool -s eth? msglvl n
-
-
-Additional Configurations
-=========================
-
-Configuring the Driver on Different Distributions
--------------------------------------------------
-
-Configuring a network driver to load properly when the system is started
-is distribution dependent.  Typically, the configuration process involves
-adding an alias line to `/etc/modprobe.d/*.conf` as well as editing other
-system startup scripts and/or configuration files.  Many popular Linux
-distributions ship with tools to make these changes for you.  To learn
-the proper way to configure a network device for your system, refer to
-your distribution documentation.  If during this process you are asked
-for the driver or module name, the name for the Linux Base Driver for
-the Intel PRO/100 Family of Adapters is e100.
-
-As an example, if you install the e100 driver for two PRO/100 adapters
-(eth0 and eth1), add the following to a configuration file in
-/etc/modprobe.d/::
-
-       alias eth0 e100
-       alias eth1 e100
-
-Viewing Link Messages
----------------------
-
-In order to see link messages and other Intel driver information on your
-console, you must set the dmesg level up to six.  This can be done by
-entering the following on the command line before loading the e100
-driver::
-
-       dmesg -n 6
-
-If you wish to see all messages issued by the driver, including debug
-messages, set the dmesg level to eight.
-
-NOTE: This setting is not saved across reboots.
-
-ethtool
--------
-
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information.  The ethtool
-version 1.6 or later is required for this functionality.
-
-The latest release of ethtool can be found from
-https://www.kernel.org/pub/software/network/ethtool/
-
-Enabling Wake on LAN (WoL)
---------------------------
-WoL is provided through the ethtool utility.  For instructions on
-enabling WoL with ethtool, refer to the ethtool man page.  WoL will be
-enabled on the system during the next shut down or reboot.  For this
-driver version, in order to enable WoL, the e100 driver must be loaded
-when shutting down or rebooting the system.
-
-NAPI
-----
-
-NAPI (Rx polling mode) is supported in the e100 driver.
-
-See https://wiki.linuxfoundation.org/networking/napi for more
-information on NAPI.
-
-Multiple Interfaces on Same Ethernet Broadcast Network
-------------------------------------------------------
-
-Due to the default ARP behavior on Linux, it is not possible to have one
-system on two IP networks in the same Ethernet broadcast domain
-(non-partitioned switch) behave as expected.  All Ethernet interfaces
-will respond to IP traffic for any IP address assigned to the system.
-This results in unbalanced receive traffic.
-
-If you have multiple interfaces in a server, either turn on ARP
-filtering by
-
-(1) entering::
-
-	echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
-
-    (this only works if your kernel's version is higher than 2.4.5), or
-
-(2) installing the interfaces in separate broadcast domains (either
-    in different switches or in a switch partitioned to VLANs).
-
-
-Support
-=======
-For general information, go to the Intel support website at:
-http://www.intel.com/support/
-
-or the Intel Wired Networking project hosted by Sourceforge at:
-http://sourceforge.net/projects/e1000
-If an issue is identified with the released source code on a supported kernel
-with a supported adapter, email the specific information related to the issue
-to e1000-devel@lists.sf.net.

-
-For more information on how to identify your adapter, go to the Adapter &
-Driver ID Guide at:
-
-    http://support.intel.com/support/go/network/adapter/idguide.htm
-
-For the latest Intel network drivers for Linux, refer to the following
-website.  In the search field, enter your adapter name or type, or use the
-networking link on the left to search for your adapter:
-
-    http://support.intel.com/support/go/network/adapter/home.htm
-
-Command Line Parameters
-=======================
-
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-NOTES:
-	For more information about the AutoNeg, Duplex, and Speed
-        parameters, see the "Speed and Duplex Configuration" section in
-        this document.
-
-        For more information about the InterruptThrottleRate,
-        RxIntDelay, TxIntDelay, RxAbsIntDelay, and TxAbsIntDelay
-        parameters, see the application note at:
-        http://www.intel.com/design/network/applnots/ap450.htm
-
-AutoNeg
--------
-
-(Supported only on adapters with copper connections)
-
-:Valid Range:   0x01-0x0F, 0x20-0x2F
-:Default Value: 0x2F
-
-This parameter is a bit-mask that specifies the speed and duplex settings
-advertised by the adapter.  When this parameter is used, the Speed and
-Duplex parameters must not be specified.
-
-NOTE:
-       Refer to the Speed and Duplex section of this readme for more
-       information on the AutoNeg parameter.
-
-Duplex
-------
-
-(Supported only on adapters with copper connections)
-
-:Valid Range:   0-2 (0=auto-negotiate, 1=half, 2=full)
-:Default Value: 0
-
-This defines the direction in which data is allowed to flow.  Can be
-either one or two-directional.  If both Duplex and the link partner are
-set to auto-negotiate, the board auto-detects the correct duplex.  If the
-link partner is forced (either full or half), Duplex defaults to half-
-duplex.
-
-FlowControl
------------
-
-:Valid Range:   0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
-:Default Value: Reads flow control settings from the EEPROM
-
-This parameter controls the automatic generation(Tx) and response(Rx)
-to Ethernet PAUSE frames.
-
-InterruptThrottleRate
----------------------
-
-(not supported on Intel(R) 82542, 82543 or 82544-based adapters)
-
-:Valid Range:
-   0,1,3,4,100-100000 (0=off, 1=dynamic, 3=dynamic conservative,
-   4=simplified balancing)
-:Default Value: 3
-
-The driver can limit the amount of interrupts per second that the adapter
-will generate for incoming packets. It does this by writing a value to the
-adapter that is based on the maximum amount of interrupts that the adapter
-will generate per second.
-
-Setting InterruptThrottleRate to a value greater or equal to 100
-will program the adapter to send out a maximum of that many interrupts
-per second, even if more packets have come in. This reduces interrupt
-load on the system and can lower CPU utilization under heavy load,
-but will increase latency as packets are not processed as quickly.
-
-The default behaviour of the driver previously assumed a static
-InterruptThrottleRate value of 8000, providing a good fallback value for
-all traffic types,but lacking in small packet performance and latency.
-The hardware can handle many more small packets per second however, and
-for this reason an adaptive interrupt moderation algorithm was implemented.
-
-Since 7.3.x, the driver has two adaptive modes (setting 1 or 3) in which
-it dynamically adjusts the InterruptThrottleRate value based on the traffic
-that it receives. After determining the type of incoming traffic in the last
-timeframe, it will adjust the InterruptThrottleRate to an appropriate value
-for that traffic.
-
-The algorithm classifies the incoming traffic every interval into
-classes.  Once the class is determined, the InterruptThrottleRate value is
-adjusted to suit that traffic type the best. There are three classes defined:
-"Bulk traffic", for large amounts of packets of normal size; "Low latency",
-for small amounts of traffic and/or a significant percentage of small
-packets; and "Lowest latency", for almost completely small packets or
-minimal traffic.
-
-In dynamic conservative mode, the InterruptThrottleRate value is set to 4000
-for traffic that falls in class "Bulk traffic". If traffic falls in the "Low
-latency" or "Lowest latency" class, the InterruptThrottleRate is increased
-stepwise to 20000. This default mode is suitable for most applications.
-
-For situations where low latency is vital such as cluster or
-grid computing, the algorithm can reduce latency even more when
-InterruptThrottleRate is set to mode 1. In this mode, which operates
-the same as mode 3, the InterruptThrottleRate will be increased stepwise to
-70000 for traffic in class "Lowest latency".
-
-In simplified mode the interrupt rate is based on the ratio of TX and
-RX traffic.  If the bytes per second rate is approximately equal, the
-interrupt rate will drop as low as 2000 interrupts per second.  If the
-traffic is mostly transmit or mostly receive, the interrupt rate could
-be as high as 8000.
-
-Setting InterruptThrottleRate to 0 turns off any interrupt moderation
-and may improve small packet latency, but is generally not suitable
-for bulk throughput traffic.
-
-NOTE:
-       InterruptThrottleRate takes precedence over the TxAbsIntDelay and
-       RxAbsIntDelay parameters.  In other words, minimizing the receive
-       and/or transmit absolute delays does not force the controller to
-       generate more interrupts than what the Interrupt Throttle Rate
-       allows.
-
-CAUTION:
-          If you are using the Intel(R) PRO/1000 CT Network Connection
-          (controller 82547), setting InterruptThrottleRate to a value
-          greater than 75,000, may hang (stop transmitting) adapters
-          under certain network conditions.  If this occurs a NETDEV
-          WATCHDOG message is logged in the system event log.  In
-          addition, the controller is automatically reset, restoring
-          the network connection.  To eliminate the potential for the
-          hang, ensure that InterruptThrottleRate is set no greater
-          than 75,000 and is not set to 0.
-
-NOTE:
-       When e1000 is loaded with default settings and multiple adapters
-       are in use simultaneously, the CPU utilization may increase non-
-       linearly.  In order to limit the CPU utilization without impacting
-       the overall throughput, we recommend that you load the driver as
-       follows::
-
-           modprobe e1000 InterruptThrottleRate=3000,3000,3000
-
-       This sets the InterruptThrottleRate to 3000 interrupts/sec for
-       the first, second, and third instances of the driver.  The range
-       of 2000 to 3000 interrupts per second works on a majority of
-       systems and is a good starting point, but the optimal value will
-       be platform-specific.  If CPU utilization is not a concern, use
-       RX_POLLING (NAPI) and default driver settings.
-
-RxDescriptors
--------------
-
-:Valid Range:
- - 48-256 for 82542 and 82543-based adapters
- - 48-4096 for all other supported adapters
-:Default Value: 256
-
-This value specifies the number of receive buffer descriptors allocated
-by the driver.  Increasing this value allows the driver to buffer more
-incoming packets, at the expense of increased system memory utilization.
-
-Each descriptor is 16 bytes.  A receive buffer is also allocated for each
-descriptor and can be either 2048, 4096, 8192, or 16384 bytes, depending
-on the MTU setting. The maximum MTU size is 16110.
-
-NOTE:
-       MTU designates the frame size.  It only needs to be set for Jumbo
-       Frames.  Depending on the available system resources, the request
-       for a higher number of receive descriptors may be denied.  In this
-       case, use a lower number.
-
-RxIntDelay
-----------
-
-:Valid Range:   0-65535 (0=off)
-:Default Value: 0
-
-This value delays the generation of receive interrupts in units of 1.024
-microseconds.  Receive interrupt reduction can improve CPU efficiency if
-properly tuned for specific network traffic.  Increasing this value adds
-extra latency to frame reception and can end up decreasing the throughput
-of TCP traffic.  If the system is reporting dropped receives, this value
-may be set too high, causing the driver to run out of available receive
-descriptors.
-
-CAUTION:
-          When setting RxIntDelay to a value other than 0, adapters may
-          hang (stop transmitting) under certain network conditions.  If
-          this occurs a NETDEV WATCHDOG message is logged in the system
-          event log.  In addition, the controller is automatically reset,
-          restoring the network connection.  To eliminate the potential
-          for the hang ensure that RxIntDelay is set to 0.
-
-RxAbsIntDelay
--------------
-
-(This parameter is supported only on 82540, 82545 and later adapters.)
-
-:Valid Range:   0-65535 (0=off)
-:Default Value: 128
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-receive interrupt is generated.  Useful only if RxIntDelay is non-zero,
-this value ensures that an interrupt is generated after the initial
-packet is received within the set amount of time.  Proper tuning,
-along with RxIntDelay, may improve traffic throughput in specific network
-conditions.
-
-Speed
------
-
-(This parameter is supported only on adapters with copper connections.)
-
-:Valid Settings: 0, 10, 100, 1000
-:Default Value:  0 (auto-negotiate at all supported speeds)
-
-Speed forces the line speed to the specified value in megabits per second
-(Mbps).  If this parameter is not specified or is set to 0 and the link
-partner is set to auto-negotiate, the board will auto-detect the correct
-speed.  Duplex should also be set when Speed is set to either 10 or 100.
-
-TxDescriptors
--------------
-
-:Valid Range:
-  - 48-256 for 82542 and 82543-based adapters
-  - 48-4096 for all other supported adapters
-:Default Value: 256
-
-This value is the number of transmit descriptors allocated by the driver.
-Increasing this value allows the driver to queue more transmits.  Each
-descriptor is 16 bytes.
-
-NOTE:
-       Depending on the available system resources, the request for a
-       higher number of transmit descriptors may be denied.  In this case,
-       use a lower number.
-
-TxIntDelay
-----------
-
-:Valid Range:   0-65535 (0=off)
-:Default Value: 8
-
-This value delays the generation of transmit interrupts in units of
-1.024 microseconds.  Transmit interrupt reduction can improve CPU
-efficiency if properly tuned for specific network traffic.  If the
-system is reporting dropped transmits, this value may be set too high
-causing the driver to run out of available transmit descriptors.
-
-TxAbsIntDelay
--------------
-
-(This parameter is supported only on 82540, 82545 and later adapters.)
-
-:Valid Range:   0-65535 (0=off)
-:Default Value: 32
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-transmit interrupt is generated.  Useful only if TxIntDelay is non-zero,
-this value ensures that an interrupt is generated after the initial
-packet is sent on the wire within the set amount of time.  Proper tuning,
-along with TxIntDelay, may improve traffic throughput in specific
-network conditions.
-
-XsumRX
-------
-
-(This parameter is NOT supported on the 82542-based adapter.)
-
-:Valid Range:   0-1
-:Default Value: 1
-
-A value of '1' indicates that the driver should enable IP checksum
-offload for received packets (both UDP and TCP) to the adapter hardware.
-
-Copybreak
----------
-
-:Valid Range:   0-xxxxxxx (0=off)
-:Default Value: 256
-:Usage: modprobe e1000.ko copybreak=128
-
-Driver copies all packets below or equaling this size to a fresh RX
-buffer before handing it up the stack.
-
-This parameter is different than other parameters, in that it is a
-single (not 1,1,1 etc.) parameter applied to all driver instances and
-it is also available during runtime at
-/sys/module/e1000/parameters/copybreak
-
-SmartPowerDownEnable
---------------------
-
-:Valid Range: 0-1
-:Default Value:  0 (disabled)
-
-Allows PHY to turn off in lower power states. The user can turn off
-this parameter in supported chipsets.
-
-Speed and Duplex Configuration
-==============================
-
-Three keywords are used to control the speed and duplex configuration.
-These keywords are Speed, Duplex, and AutoNeg.
-
-If the board uses a fiber interface, these keywords are ignored, and the
-fiber interface board only links at 1000 Mbps full-duplex.
-
-For copper-based boards, the keywords interact as follows:
-
-- The default operation is auto-negotiate.  The board advertises all
-  supported speed and duplex combinations, and it links at the highest
-  common speed and duplex mode IF the link partner is set to auto-negotiate.
-
-- If Speed = 1000, limited auto-negotiation is enabled and only 1000 Mbps
-  is advertised (The 1000BaseT spec requires auto-negotiation.)
-
-- If Speed = 10 or 100, then both Speed and Duplex should be set.  Auto-
-  negotiation is disabled, and the AutoNeg parameter is ignored.  Partner
-  SHOULD also be forced.
-
-The AutoNeg parameter is used when more control is required over the
-auto-negotiation process.  It should be used when you wish to control which
-speed and duplex combinations are advertised during the auto-negotiation
-process.
-
-The parameter may be specified as either a decimal or hexadecimal value as
-determined by the bitmap below.
-
-============== ====== ====== ======= ======= ====== ====== ======= ======
-Bit position   7      6      5       4       3      2      1       0
-Decimal Value  128    64     32      16      8      4      2       1
-Hex value      80     40     20      10      8      4      2       1
-Speed (Mbps)   N/A    N/A    1000    N/A     100    100    10      10
-Duplex                       Full            Full   Half   Full    Half
-============== ====== ====== ======= ======= ====== ====== ======= ======
-
-Some examples of using AutoNeg::
-
-  modprobe e1000 AutoNeg=0x01 (Restricts autonegotiation to 10 Half)
-  modprobe e1000 AutoNeg=1 (Same as above)
-  modprobe e1000 AutoNeg=0x02 (Restricts autonegotiation to 10 Full)
-  modprobe e1000 AutoNeg=0x03 (Restricts autonegotiation to 10 Half or 10 Full)
-  modprobe e1000 AutoNeg=0x04 (Restricts autonegotiation to 100 Half)
-  modprobe e1000 AutoNeg=0x05 (Restricts autonegotiation to 10 Half or 100
-  Half)
-  modprobe e1000 AutoNeg=0x020 (Restricts autonegotiation to 1000 Full)
-  modprobe e1000 AutoNeg=32 (Same as above)
-
-Note that when this parameter is used, Speed and Duplex must not be specified.
-
-If the link partner is forced to a specific speed and duplex, then this
-parameter should not be used.  Instead, use the Speed and Duplex parameters
-previously mentioned to force the adapter to the same speed and duplex.
-
-Additional Configurations
-=========================
-
-Jumbo Frames
-------------
-
-  Jumbo Frames support is enabled by changing the MTU to a value larger than
-  the default of 1500.  Use the ifconfig command to increase the MTU size.
-  For example::
-
-       ifconfig eth<x> mtu 9000 up
-
-  This setting is not saved across reboots.  It can be made permanent if
-  you add::
-
-       MTU=9000
-
-  to the file /etc/sysconfig/network-scripts/ifcfg-eth<x>.  This example
-  applies to the Red Hat distributions; other distributions may store this
-  setting in a different location.
-
-Notes:
-  Degradation in throughput performance may be observed in some Jumbo frames
-  environments. If this is observed, increasing the application's socket buffer
-  size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
-  See the specific application manual and /usr/src/linux*/Documentation/
-  networking/ip-sysctl.txt for more details.
-
-  - The maximum MTU setting for Jumbo Frames is 16110.  This value coincides
-    with the maximum Jumbo Frames size of 16128.
-
-  - Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
-    poor performance or loss of link.
-
-  - Adapters based on the Intel(R) 82542 and 82573V/E controller do not
-    support Jumbo Frames. These correspond to the following product names::
-
-     Intel(R) PRO/1000 Gigabit Server Adapter
-     Intel(R) PRO/1000 PM Network Connection
-
-ethtool
--------
-
-  The driver utilizes the ethtool interface for driver configuration and
-  diagnostics, as well as displaying statistical information.  The ethtool
-  version 1.6 or later is required for this functionality.
-
-  The latest release of ethtool can be found from
-  https://www.kernel.org/pub/software/network/ethtool/
-
-Enabling Wake on LAN (WoL)
---------------------------
-
-  WoL is configured through the ethtool utility.
-
-  WoL will be enabled on the system during the next shut down or reboot.
-  For this driver version, in order to enable WoL, the e1000 driver must be
-  loaded when shutting down or rebooting the system.

-Identifying Your Adapter
-========================
-For information on how to identify your adapter, and for the latest Intel
-network drivers, refer to the Intel Support website:
-https://www.intel.com/support
-
-
-Command Line Parameters
-=======================
-If the driver is built as a module, the following optional parameters are used
-by entering them on the command line with the modprobe command using this
-syntax::
-
-    modprobe e1000e [<option>=<VAL1>,<VAL2>,...]
-
-There needs to be a <VAL#> for each network port in the system supported by
-this driver. The values will be applied to each instance, in function order.
-For example::
-
-    modprobe e1000e InterruptThrottleRate=16000,16000
-
-In this case, there are two network ports supported by e1000e in the system.
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-NOTE: A descriptor describes a data buffer and attributes related to the data
-buffer. This information is accessed by the hardware.
-
-InterruptThrottleRate
----------------------
-:Valid Range: 0,1,3,4,100-100000
-:Default Value: 3
-
-Interrupt Throttle Rate controls the number of interrupts each interrupt
-vector can generate per second. Increasing ITR lowers latency at the cost of
-increased CPU utilization, though it may help throughput in some circumstances.
-
-Setting InterruptThrottleRate to a value greater or equal to 100
-will program the adapter to send out a maximum of that many interrupts
-per second, even if more packets have come in. This reduces interrupt
-load on the system and can lower CPU utilization under heavy load,
-but will increase latency as packets are not processed as quickly.
-
-The default behaviour of the driver previously assumed a static
-InterruptThrottleRate value of 8000, providing a good fallback value for
-all traffic types, but lacking in small packet performance and latency.
-The hardware can handle many more small packets per second however, and
-for this reason an adaptive interrupt moderation algorithm was implemented.
-
-The driver has two adaptive modes (setting 1 or 3) in which
-it dynamically adjusts the InterruptThrottleRate value based on the traffic
-that it receives. After determining the type of incoming traffic in the last
-timeframe, it will adjust the InterruptThrottleRate to an appropriate value
-for that traffic.
-
-The algorithm classifies the incoming traffic every interval into
-classes.  Once the class is determined, the InterruptThrottleRate value is
-adjusted to suit that traffic type the best. There are three classes defined:
-"Bulk traffic", for large amounts of packets of normal size; "Low latency",
-for small amounts of traffic and/or a significant percentage of small
-packets; and "Lowest latency", for almost completely small packets or
-minimal traffic.
-
- - 0: Off
-      Turns off any interrupt moderation and may improve small packet latency.
-      However, this is generally not suitable for bulk throughput traffic due
-      to the increased CPU utilization of the higher interrupt rate.
- - 1: Dynamic mode
-      This mode attempts to moderate interrupts per vector while maintaining
-      very low latency. This can sometimes cause extra CPU utilization. If
-      planning on deploying e1000e in a latency sensitive environment, this
-      parameter should be considered.
- - 3: Dynamic Conservative mode (default)
-      In dynamic conservative mode, the InterruptThrottleRate value is set to
-      4000 for traffic that falls in class "Bulk traffic". If traffic falls in
-      the "Low latency" or "Lowest latency" class, the InterruptThrottleRate is
-      increased stepwise to 20000. This default mode is suitable for most
-      applications.
- - 4: Simplified Balancing mode
-      In simplified mode the interrupt rate is based on the ratio of TX and
-      RX traffic.  If the bytes per second rate is approximately equal, the
-      interrupt rate will drop as low as 2000 interrupts per second.  If the
-      traffic is mostly transmit or mostly receive, the interrupt rate could
-      be as high as 8000.
- - 100-100000:
-      Setting InterruptThrottleRate to a value greater or equal to 100
-      will program the adapter to send at most that many interrupts per second,
-      even if more packets have come in. This reduces interrupt load on the
-      system and can lower CPU utilization under heavy load, but will increase
-      latency as packets are not processed as quickly.
-
-NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
-RxAbsIntDelay parameters. In other words, minimizing the receive and/or
-transmit absolute delays does not force the controller to generate more
-interrupts than what the Interrupt Throttle Rate allows.
-
-RxIntDelay
-----------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 0
-
-This value delays the generation of receive interrupts in units of 1.024
-microseconds. Receive interrupt reduction can improve CPU efficiency if
-properly tuned for specific network traffic. Increasing this value adds extra
-latency to frame reception and can end up decreasing the throughput of TCP
-traffic. If the system is reporting dropped receives, this value may be set
-too high, causing the driver to run out of available receive descriptors.
-
-CAUTION: When setting RxIntDelay to a value other than 0, adapters may hang
-(stop transmitting) under certain network conditions. If this occurs a NETDEV
-WATCHDOG message is logged in the system event log. In addition, the
-controller is automatically reset, restoring the network connection. To
-eliminate the potential for the hang ensure that RxIntDelay is set to 0.
-
-RxAbsIntDelay
--------------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 8
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-receive interrupt is generated. This value ensures that an interrupt is
-generated after the initial packet is received within the set amount of time,
-which is useful only if RxIntDelay is non-zero. Proper tuning, along with
-RxIntDelay, may improve traffic throughput in specific network conditions.
-
-TxIntDelay
-----------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 8
-
-This value delays the generation of transmit interrupts in units of 1.024
-microseconds. Transmit interrupt reduction can improve CPU efficiency if
-properly tuned for specific network traffic. If the system is reporting
-dropped transmits, this value may be set too high causing the driver to run
-out of available transmit descriptors.
-
-TxAbsIntDelay
--------------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 32
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-transmit interrupt is generated. It is useful only if TxIntDelay is non-zero.
-It ensures that an interrupt is generated after the initial Packet is sent on
-the wire within the set amount of time. Proper tuning, along with TxIntDelay,
-may improve traffic throughput in specific network conditions.
-
-copybreak
----------
-:Valid Range: 0-xxxxxxx (0=off)
-:Default Value: 256
-
-The driver copies all packets below or equaling this size to a fresh receive
-buffer before handing it up the stack.
-This parameter differs from other parameters because it is a single (not 1,1,1
-etc.) parameter applied to all driver instances and it is also available
-during runtime at /sys/module/e1000e/parameters/copybreak.
-
-To use copybreak, type::
-
-    modprobe e1000e.ko copybreak=128
-
-SmartPowerDownEnable
---------------------
-:Valid Range: 0,1
-:Default Value: 0 (disabled)
-
-Allows the PHY to turn off in lower power states. The user can turn off this
-parameter in supported chipsets.
-
-KumeranLockLoss
----------------
-:Valid Range: 0,1
-:Default Value: 1 (enabled)
-
-This workaround skips resetting the PHY at shutdown for the initial silicon
-releases of ICH8 systems.
-
-IntMode
--------
-:Valid Range: 0-2
-:Default Value: 0
-
-   +-------+----------------+
-   | Value | Interrupt Mode |
-   +=======+================+
-   |   0   |     Legacy     |
-   +-------+----------------+
-   |   1   |       MSI      |
-   +-------+----------------+
-   |   2   |      MSI-X     |
-   +-------+----------------+
-
-IntMode allows load time control over the type of interrupt registered for by
-the driver. MSI-X is required for multiple queue support, and some kernels and
-combinations of kernel .config options will force a lower level of interrupt
-support.
-
-This command will show different values for each type of interrupt::
-
-  cat /proc/interrupts
-
-CrcStripping
-------------
-:Valid Range: 0,1
-:Default Value: 1 (enabled)
-
-Strip the CRC from received packets before sending up the network stack. If
-you have a machine with a BMC enabled but cannot receive IPMI traffic after
-loading or enabling the driver, try disabling this feature.
-
-WriteProtectNVM
----------------
-:Valid Range: 0,1
-:Default Value: 1 (enabled)
-
-If set to 1, configure the hardware to ignore all write/erase cycles to the
-GbE region in the ICHx NVM (in order to prevent accidental corruption of the
-NVM). This feature can be disabled by setting the parameter to 0 during initial
-driver load.
-
-NOTE: The machine must be power cycled (full off/on) when enabling NVM writes
-via setting the parameter to zero. Once the NVM has been locked (via the
-parameter at 1 when the driver loads) it cannot be unlocked except via power
-cycle.
-
-Debug
------
-:Valid Range: 0-16 (0=none,...,16=all)
-:Default Value: 0
-
-This parameter adjusts the level of debug messages displayed in the system logs.
-
-
-Additional Features and Configurations
-======================================
-
-Jumbo Frames
-------------
-Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
-to a value larger than the default value of 1500.
-
-Use the ifconfig command to increase the MTU size. For example, enter the
-following where <x> is the interface number::
-
-    ifconfig eth<x> mtu 9000 up
-
-Alternatively, you can use the ip command as follows::
-
-    ip link set mtu 9000 dev eth<x>
-    ip link set up dev eth<x>
-
-This setting is not saved across reboots. The setting change can be made
-permanent by adding 'MTU=9000' to the file:
-
-- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
-- For SLES: /etc/sysconfig/network/<config_file>
-
-NOTE: The maximum MTU setting for Jumbo Frames is 8996. This value coincides
-with the maximum Jumbo Frames size of 9018 bytes.
-
-NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
-poor performance or loss of link.
-
-NOTE: The following adapters limit Jumbo Frames sized packets to a maximum of
-4088 bytes:
-
-  - Intel(R) 82578DM Gigabit Network Connection
-  - Intel(R) 82577LM Gigabit Network Connection
-
-The following adapters do not support Jumbo Frames:
-
-  - Intel(R) PRO/1000 Gigabit Server Adapter
-  - Intel(R) PRO/1000 PM Network Connection
-  - Intel(R) 82562G 10/100 Network Connection
-  - Intel(R) 82562G-2 10/100 Network Connection
-  - Intel(R) 82562GT 10/100 Network Connection
-  - Intel(R) 82562GT-2 10/100 Network Connection
-  - Intel(R) 82562V 10/100 Network Connection
-  - Intel(R) 82562V-2 10/100 Network Connection
-  - Intel(R) 82566DC Gigabit Network Connection
-  - Intel(R) 82566DC-2 Gigabit Network Connection
-  - Intel(R) 82566DM Gigabit Network Connection
-  - Intel(R) 82566MC Gigabit Network Connection
-  - Intel(R) 82566MM Gigabit Network Connection
-  - Intel(R) 82567V-3 Gigabit Network Connection
-  - Intel(R) 82577LC Gigabit Network Connection
-  - Intel(R) 82578DC Gigabit Network Connection
-
-NOTE: Jumbo Frames cannot be configured on an 82579-based Network device if
-MACSec is enabled on the system.
-
-
-ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information. The latest ethtool
-version is required for this functionality. Download it at:
-
-https://www.kernel.org/pub/software/network/ethtool/
-
-NOTE: When validating enable/disable tests on some parts (for example, 82578),
-it is necessary to add a few seconds between tests when working with ethtool.
-
-
-Speed and Duplex Configuration
-------------------------------
-In addressing speed and duplex configuration issues, you need to distinguish
-between copper-based adapters and fiber-based adapters.
-
-In the default mode, an Intel(R) Ethernet Network Adapter using copper
-connections will attempt to auto-negotiate with its link partner to determine
-the best setting. If the adapter cannot establish link with the link partner
-using auto-negotiation, you may need to manually configure the adapter and link
-partner to identical settings to establish link and pass packets. This should
-only be needed when attempting to link with an older switch that does not
-support auto-negotiation or one that has been forced to a specific speed or
-duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
-and higher cannot be forced. Use the autonegotiation advertising setting to
-manually set devices for 1 Gbps and higher.
-
-Speed, duplex, and autonegotiation advertising are configured through the
-ethtool utility.
-
-Caution: Only experienced network administrators should force speed and duplex
-or change autonegotiation advertising manually. The settings at the switch must
-always match the adapter settings. Adapter performance may suffer or your
-adapter may not operate if you configure the adapter differently from your
-switch.
-
-An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
-will not attempt to auto-negotiate with its link partner since those adapters
-operate only in full duplex and only at their native speed.
-
-
-Enabling Wake on LAN (WoL)
---------------------------
-WoL is configured through the ethtool utility.
-
-WoL will be enabled on the system during the next shut down or reboot. For
-this driver version, in order to enable WoL, the e1000e driver must be loaded
-prior to shutting down or suspending the system.
-
-NOTE: Wake on LAN is only supported on port A for the following devices:
-- Intel(R) PRO/1000 PT Dual Port Network Connection
-- Intel(R) PRO/1000 PT Dual Port Server Connection
-- Intel(R) PRO/1000 PT Dual Port Server Adapter
-- Intel(R) PRO/1000 PF Dual Port Server Adapter
-- Intel(R) PRO/1000 PT Quad Port Server Adapter
-- Intel(R) Gigabit PT Quad Port Server ExpressModule

-Identifying Your Adapter
-========================
-The driver in this release is compatible with devices based on the Intel(R)
-Ethernet Multi-host Controller.
-
-For information on how to identify your adapter, and for the latest Intel
-network drivers, refer to the Intel Support website:
-http://www.intel.com/support
-
-
-Flow Control
-------------
-The Intel(R) Ethernet Switch Host Interface Driver does not support Flow
-Control. It will not send pause frames. This may result in dropped frames.
-
-
-Virtual Functions (VFs)
------------------------
-Use sysfs to enable VFs.
-Valid Range: 0-64
-
-For example::
-
-    echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs //enable VFs
-    echo 0 > /sys/class/net/$dev/device/sriov_numvfs //disable VFs
-
-NOTE: Neither the device nor the driver control how VFs are mapped into config
-space. Bus layout will vary by operating system. On operating systems that
-support it, you can check sysfs to find the mapping.
-
-NOTE: When SR-IOV mode is enabled, hardware VLAN filtering and VLAN tag
-stripping/insertion will remain enabled. Please remove the old VLAN filter
-before the new VLAN filter is added. For example::
-
-    ip link set eth0 vf 0 vlan 100	// set vlan 100 for VF 0
-    ip link set eth0 vf 0 vlan 0	// Delete vlan 100
-    ip link set eth0 vf 0 vlan 200	// set a new vlan 200 for VF 0
-
-
-Additional Features and Configurations
-======================================
-
-Jumbo Frames
-------------
-Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
-to a value larger than the default value of 1500.
-
-Use the ifconfig command to increase the MTU size. For example, enter the
-following where <x> is the interface number::
-
-    ifconfig eth<x> mtu 9000 up
-
-Alternatively, you can use the ip command as follows::
-
-    ip link set mtu 9000 dev eth<x>
-    ip link set up dev eth<x>
-
-This setting is not saved across reboots. The setting change can be made
-permanent by adding 'MTU=9000' to the file:
-
-- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
-- For SLES: /etc/sysconfig/network/<config_file>
-
-NOTE: The maximum MTU setting for Jumbo Frames is 15342. This value coincides
-with the maximum Jumbo Frames size of 15364 bytes.
-
-NOTE: This driver will attempt to use multiple page sized buffers to receive
-each jumbo packet. This should help to avoid buffer starvation issues when
-allocating receive packets.
-
-
-Generic Receive Offload, aka GRO
---------------------------------
-The driver supports the in-kernel software implementation of GRO. GRO has
-shown that by coalescing Rx traffic into larger chunks of data, CPU
-utilization can be significantly reduced when under large Rx load. GRO is an
-evolution of the previously-used LRO interface. GRO is able to coalesce
-other protocols besides TCP. It's also safe to use with configurations that
-are problematic for LRO, namely bridging and iSCSI.
-
-
-
-Supported ethtool Commands and Options for Filtering

-Identifying Your Adapter
-========================
-The driver is compatible with devices based on the following:
-
- * Intel(R) Ethernet Controller X710
- * Intel(R) Ethernet Controller XL710
- * Intel(R) Ethernet Network Connection X722
- * Intel(R) Ethernet Controller XXV710

-
-NOTE: Some adapters based on the Intel(R) Ethernet Controller 700 Series only
-support Intel Ethernet Optics modules. On these adapters, other modules are not
-supported and will not function.  In all cases Intel recommends using Intel
-Ethernet Optics; other modules may function but are not validated by Intel.
-Contact Intel for supported media types.
-
-NOTE: For connections based on Intel(R) Ethernet Controller 700 Series, support
-is dependent on your system board. Please see your vendor for details.
-
-NOTE: In systems that do not have adequate airflow to cool the adapter and
-optical modules, you must use high temperature optical modules.
-
-Virtual Functions (VFs)
------------------------
-Use sysfs to enable VFs. For example::
-
-  #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs #enable VFs
-  #echo 0 > /sys/class/net/$dev/device/sriov_numvfs #disable VFs
-
-For example, the following instructions will configure PF eth0 and the first VF
-on VLAN 10::
-
-  $ ip link set dev eth0 vf 0 vlan 10
-
-VLAN Tag Packet Steering
-------------------------
-Allows you to send all packets with a specific VLAN tag to a particular SR-IOV
-virtual function (VF). Further, this feature allows you to designate a
-particular VF as trusted, and allows that trusted VF to request selective
-promiscuous mode on the Physical Function (PF).
-
-To set a VF as trusted or untrusted, enter the following command in the
-Hypervisor::
-
-  # ip link set dev eth0 vf 1 trust [on|off]
-
-Once the VF is designated as trusted, use the following commands in the VM to
-set the VF to promiscuous mode.
-
-::
-
-  For promiscuous all:
-  #ip link set eth2 promisc on
-  Where eth2 is a VF interface in the VM
-
-  For promiscuous Multicast:
-  #ip link set eth2 allmulticast on
-  Where eth2 is a VF interface in the VM
-
-NOTE: By default, the ethtool priv-flag vf-true-promisc-support is set to
-"off",meaning that promiscuous mode for the VF will be limited. To set the
-promiscuous mode for the VF to true promiscuous and allow the VF to see all
-ingress traffic, use the following command::
-
-  #ethtool -set-priv-flags p261p1 vf-true-promisc-support on
-
-The vf-true-promisc-support priv-flag does not enable promiscuous mode; rather,
-it designates which type of promiscuous mode (limited or true) you will get
-when you enable promiscuous mode using the ip link commands above. Note that
-this is a global setting that affects the entire device. However,the
-vf-true-promisc-support priv-flag is only exposed to the first PF of the
-device. The PF remains in limited promiscuous mode (unless it is in MFP mode)
-regardless of the vf-true-promisc-support setting.
-
-Now add a VLAN interface on the VF interface::
-
-  #ip link add link eth2 name eth2.100 type vlan id 100
-
-Note that the order in which you set the VF to promiscuous mode and add the
-VLAN interface does not matter (you can do either first). The end result in
-this example is that the VF will get all traffic that is tagged with VLAN 100.
-
-Intel(R) Ethernet Flow Director
--------------------------------
-The Intel Ethernet Flow Director performs the following tasks:
-
-- Directs receive packets according to their flows to different queues.
-- Enables tight control on routing a flow in the platform.
-- Matches flows and CPU cores for flow affinity.
-- Supports multiple parameters for flexible flow classification and load
-  balancing (in SFP mode only).
-
-NOTE: The Linux i40e driver supports the following flow types: IPv4, TCPv4, and
-UDPv4. For a given flow type, it supports valid combinations of IP addresses
-(source or destination) and UDP/TCP ports (source and destination). For
-example, you can supply only a source IP address, a source IP address and a
-destination port, or any combination of one or more of these four parameters.
-
-NOTE: The Linux i40e driver allows you to filter traffic based on a
-user-defined flexible two-byte pattern and offset by using the ethtool user-def
-and mask fields. Only L3 and L4 flow types are supported for user-defined
-flexible filters. For a given flow type, you must clear all Intel Ethernet Flow
-Director filters before changing the input set (for that flow type).
-
-To enable or disable the Intel Ethernet Flow Director::
-
-  # ethtool -K ethX ntuple <on|off>
-
-When disabling ntuple filters, all the user programmed filters are flushed from
-the driver cache and hardware. All needed filters must be re-added when ntuple
-is re-enabled.
-
-To add a filter that directs packet to queue 2, use -U or -N switch::
-
-  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
-  192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
-
-To set a filter using only the source and destination IP address::
-
-  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
-  192.168.10.2 action 2 [loc 1]
-
-To see the list of filters currently present::
-
-  # ethtool <-u|-n> ethX
-
-Application Targeted Routing (ATR) Perfect Filters
---------------------------------------------------
-ATR is enabled by default when the kernel is in multiple transmit queue mode.
-An ATR Intel Ethernet Flow Director filter rule is added when a TCP-IP flow
-starts and is deleted when the flow ends. When a TCP-IP Intel Ethernet Flow
-Director rule is added from ethtool (Sideband filter), ATR is turned off by the
-driver. To re-enable ATR, the sideband can be disabled with the ethtool -K
-option. For example::
-
-  ethtool –K [adapter] ntuple [off|on]
-
-If sideband is re-enabled after ATR is re-enabled, ATR remains enabled until a
-TCP-IP flow is added. When all TCP-IP sideband rules are deleted, ATR is
-automatically re-enabled.
-
-Packets that match the ATR rules are counted in fdir_atr_match stats in
-ethtool, which also can be used to verify whether ATR rules still exist.
-
-Sideband Perfect Filters
-------------------------
-Sideband Perfect Filters are used to direct traffic that matches specified
-characteristics. They are enabled through ethtool's ntuple interface. To add a
-new filter use the following command::
-
-  ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
-  dst-port <port> action <queue>
-
-Where:
-  <device> - the ethernet device to program
-  <type> - can be ip4, tcp4, udp4, or sctp4
-  <ip> - the ip address to match on
-  <port> - the port number to match on
-  <queue> - the queue to direct traffic towards (-1 discards matching traffic)
-
-Use the following command to display all of the active filters::
-
-  ethtool -u <device>
-
-Use the following command to delete a filter::
-
-  ethtool -U <device> delete <N>
-
-Where <N> is the filter id displayed when printing all the active filters, and
-may also have been specified using "loc <N>" when adding the filter.
-
-The following example matches TCP traffic sent from 192.168.0.1, port 5300,
-directed to 192.168.0.5, port 80, and sends it to queue 7::
-
-  ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
-  src-port 5300 dst-port 80 action 7
-
-For each flow-type, the programmed filters must all have the same matching
-input set. For example, issuing the following two commands is acceptable::
-
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
-
-Issuing the next two commands, however, is not acceptable, since the first
-specifies src-ip and the second specifies dst-ip::
-
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
-  ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
-
-The second command will fail with an error. You may program multiple filters
-with the same fields, using different values, but, on one device, you may not
-program two tcp4 filters with different matching fields.
-
-Matching on a sub-portion of a field is not supported by the i40e driver, thus
-partial mask fields are not supported.
-
-The driver also supports matching user-defined data within the packet payload.
-This flexible data is specified using the "user-def" field of the ethtool
-command in the following way:
-
-+----------------------------+--------------------------+
-| 31    28    24    20    16 | 15    12    8    4    0  |
-+----------------------------+--------------------------+
-| offset into packet payload | 2 bytes of flexible data |
-+----------------------------+--------------------------+
-
-For example,
-
-::
-
-  ... user-def 0x4FFFF ...
-
-tells the filter to look 4 bytes into the payload and match that value against
-0xFFFF. The offset is based on the beginning of the payload, and not the
-beginning of the packet. Thus
-
-::
-
-  flow-type tcp4 ... user-def 0x8BEAF ...
-
-would match TCP/IPv4 packets which have the value 0xBEAF 8 bytes into the
-TCP/IPv4 payload.
-
-Note that ICMP headers are parsed as 4 bytes of header and 4 bytes of payload.
-Thus to match the first byte of the payload, you must actually add 4 bytes to
-the offset. Also note that ip4 filters match both ICMP frames as well as raw
-(unknown) ip4 frames, where the payload will be the L3 payload of the IP4 frame.
-
-The maximum offset is 64. The hardware will only read up to 64 bytes of data
-from the payload. The offset must be even because the flexible data is 2 bytes
-long and must be aligned to byte 0 of the packet payload.
-
-The user-defined flexible offset is also considered part of the input set and
-cannot be programmed separately for multiple filters of the same type. However,
-the flexible data is not part of the input set and multiple filters may use the
-same offset but match against different data.
-
-To create filters that direct traffic to a specific Virtual Function, use the
-"action" parameter. Specify the action as a 64 bit value, where the lower 32
-bits represents the queue number, while the next 8 bits represent which VF.
-Note that 0 is the PF, so the VF identifier is offset by 1. For example::
-
-  ... action 0x800000002 ...
-
-specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
-that VF.
-
-Note that these filters will not break internal routing rules, and will not
-route traffic that otherwise would not have been sent to the specified Virtual
-Function.
-
-Setting the link-down-on-close Private Flag
--------------------------------------------
-When the link-down-on-close private flag is set to "on", the port's link will
-go down when the interface is brought down using the ifconfig ethX down command.
-
-Use ethtool to view and set link-down-on-close, as follows::
-
-  ethtool --show-priv-flags ethX
-  ethtool --set-priv-flags ethX link-down-on-close [on|off]
-
-Viewing Link Messages
----------------------
-Link messages will not be displayed to the console if the distribution is
-restricting system messages. In order to see network driver link messages on
-your console, set dmesg to eight by entering the following::
-
-  dmesg -n 8
-
-NOTE: This setting is not saved across reboots.
-
-Jumbo Frames
-------------
-Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
-to a value larger than the default value of 1500.
-
-Use the ifconfig command to increase the MTU size. For example, enter the
-following where <x> is the interface number::
-
-  ifconfig eth<x> mtu 9000 up
-
-Alternatively, you can use the ip command as follows::
-
-  ip link set mtu 9000 dev eth<x>
-  ip link set up dev eth<x>
-
-This setting is not saved across reboots. The setting change can be made
-permanent by adding 'MTU=9000' to the file::
-
-  /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
-  /etc/sysconfig/network/<config_file> // for SLES
-
-NOTE: The maximum MTU setting for Jumbo Frames is 9702. This value coincides
-with the maximum Jumbo Frames size of 9728 bytes.
-
-NOTE: This driver will attempt to use multiple page sized buffers to receive
-each jumbo packet. This should help to avoid buffer starvation issues when
-allocating receive packets.
-
-ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information. The latest ethtool
-version is required for this functionality. Download it at:
-https://www.kernel.org/pub/software/network/ethtool/
-
-Supported ethtool Commands and Options for Filtering
-----------------------------------------------------
--n --show-nfc
-  Retrieves the receive network flow classification configurations.
-
-rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6
-  Retrieves the hash options for the specified network traffic type.
-
--N --config-nfc
-  Configures the receive network flow classification.
-
-rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 m|v|t|s|d|f|n|r...
-  Configures the hash options for the specified network traffic type.
-
-udp4 UDP over IPv4
-udp6 UDP over IPv6
-
-f Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
-n Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
-
-Speed and Duplex Configuration
-------------------------------
-In addressing speed and duplex configuration issues, you need to distinguish
-between copper-based adapters and fiber-based adapters.
-
-In the default mode, an Intel(R) Ethernet Network Adapter using copper
-connections will attempt to auto-negotiate with its link partner to determine
-the best setting. If the adapter cannot establish link with the link partner
-using auto-negotiation, you may need to manually configure the adapter and link
-partner to identical settings to establish link and pass packets. This should
-only be needed when attempting to link with an older switch that does not
-support auto-negotiation or one that has been forced to a specific speed or
-duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
-and higher cannot be forced. Use the autonegotiation advertising setting to
-manually set devices for 1 Gbps and higher.
-
-NOTE: You cannot set the speed for devices based on the Intel(R) Ethernet
-Network Adapter XXV710 based devices.
-
-Speed, duplex, and autonegotiation advertising are configured through the
-ethtool utility.
-
-Caution: Only experienced network administrators should force speed and duplex
-or change autonegotiation advertising manually. The settings at the switch must
-always match the adapter settings. Adapter performance may suffer or your
-adapter may not operate if you configure the adapter differently from your
-switch.
-
-An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
-will not attempt to auto-negotiate with its link partner since those adapters
-operate only in full duplex and only at their native speed.
-
-NAPI
-----
-NAPI (Rx polling mode) is supported in the i40e driver.
-For more information on NAPI, see
-https://wiki.linuxfoundation.org/networking/napi
-
-Flow Control
-------------
-Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
-receiving and transmitting pause frames for i40e. When transmit is enabled,
-pause frames are generated when the receive packet buffer crosses a predefined
-threshold. When receive is enabled, the transmit unit will halt for the time
-delay specified when a pause frame is received.
-
-NOTE: You must have a flow control capable link partner.
-
-Flow Control is on by default.
-
-Use ethtool to change the flow control settings.
-
-To enable or disable Rx or Tx Flow Control::
-
-  ethtool -A eth? rx <on|off> tx <on|off>
-
-Note: This command only enables or disables Flow Control if auto-negotiation is
-disabled. If auto-negotiation is enabled, this command changes the parameters
-used for auto-negotiation with the link partner.
-
-To enable or disable auto-negotiation::
-
-  ethtool -s eth? autoneg <on|off>
-
-Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
-on your device, you may not be able to change the auto-negotiation setting.
-
-RSS Hash Flow
--------------
-Allows you to set the hash bytes per flow type and any combination of one or
-more options for Receive Side Scaling (RSS) hash byte configuration.
-
-::
-
-  # ethtool -N <dev> rx-flow-hash <type> <option>
-
-Where <type> is:
-  tcp4	signifying TCP over IPv4
-  udp4	signifying UDP over IPv4
-  tcp6	signifying TCP over IPv6
-  udp6	signifying UDP over IPv6
-And <option> is one or more of:
-  s	Hash on the IP source address of the Rx packet.
-  d	Hash on the IP destination address of the Rx packet.
-  f	Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
-  n	Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
-
-MAC and VLAN anti-spoofing feature
-----------------------------------
-When a malicious driver attempts to send a spoofed packet, it is dropped by the
-hardware and not transmitted.
-NOTE: This feature can be disabled for a specific Virtual Function (VF)::
-
-  ip link set <pf dev> vf <vf id> spoofchk {off|on}
-
-IEEE 1588 Precision Time Protocol (PTP) Hardware Clock (PHC)
-------------------------------------------------------------
-Precision Time Protocol (PTP) is used to synchronize clocks in a computer
-network. PTP support varies among Intel devices that support this driver. Use
-"ethtool -T <netdev name>" to get a definitive list of PTP capabilities
-supported by the device.
-
-IEEE 802.1ad (QinQ) Support
----------------------------
-The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
-IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
-"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
-allow L2 tunneling and the ability to segregate traffic within a particular
-VLAN ID, among other uses.
-
-The following are examples of how to configure 802.1ad (QinQ)::
-
-  ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
-  ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
-
-Where "24" and "371" are example VLAN IDs.
-
-NOTES:
-  Receive checksum offloads, cloud filters, and VLAN acceleration are not
-  supported for 802.1ad (QinQ) packets.
-
-VXLAN and GENEVE Overlay HW Offloading
---------------------------------------
-Virtual Extensible LAN (VXLAN) allows you to extend an L2 network over an L3
-network, which may be useful in a virtualized or cloud environment. Some
-Intel(R) Ethernet Network devices perform VXLAN processing, offloading it from
-the operating system. This reduces CPU utilization.
-
-VXLAN offloading is controlled by the Tx and Rx checksum offload options
-provided by ethtool. That is, if Tx checksum offload is enabled, and the
-adapter has the capability, VXLAN offloading is also enabled.
-
-Support for VXLAN and GENEVE HW offloading is dependent on kernel support of
-the HW offloading features.
-
-Multiple Functions per Port
----------------------------
-Some adapters based on the Intel Ethernet Controller X710/XL710 support
-multiple functions on a single physical port. Configure these functions through
-the System Setup/BIOS.
-
-Minimum TX Bandwidth is the guaranteed minimum data transmission bandwidth, as
-a percentage of the full physical port link speed, that the partition will
-receive. The bandwidth the partition is awarded will never fall below the level
-you specify.
-
-The range for the minimum bandwidth values is:
-1 to ((100 minus # of partitions on the physical port) plus 1)
-For example, if a physical port has 4 partitions, the range would be:
-1 to ((100 - 4) + 1 = 97)
-
-The Maximum Bandwidth percentage represents the maximum transmit bandwidth
-allocated to the partition as a percentage of the full physical port link
-speed. The accepted range of values is 1-100. The value is used as a limiter,
-should you chose that any one particular function not be able to consume 100%
-of a port's bandwidth (should it be available). The sum of all the values for
-Maximum Bandwidth is not restricted, because no more than 100% of a port's
-bandwidth can ever be used.
-
-NOTE: X710/XXV710 devices fail to enable Max VFs (64) when Multiple Functions
-per Port (MFP) and SR-IOV are enabled. An error from i40e is logged that says
-"add vsi failed for VF N, aq_err 16". To workaround the issue, enable less than
-64 virtual functions (VFs).
-
-Data Center Bridging (DCB)
---------------------------
-DCB is a configuration Quality of Service implementation in hardware. It uses
-the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
-different priorities that traffic can be filtered into. It also enables
-priority flow control (802.1Qbb) which can limit or eliminate the number of
-dropped packets during network stress. Bandwidth can be allocated to each of
-these priorities, which is enforced at the hardware level (802.1Qaz).
-
-Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
-802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
-and can accept settings from a DCBX capable peer. Software configuration of
-DCBX parameters via dcbtool/lldptool are not supported.
-
-NOTE: Firmware LLDP can be disabled by setting the private flag disable-fw-lldp.
-
-The i40e driver implements the DCB netlink interface layer to allow user-space
-to communicate with the driver and query DCB configuration for the port.
-
-NOTE:
-The kernel assumes that TC0 is available, and will disable Priority Flow
-Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
-enabled when setting up DCB on your switch.
-
-Interrupt Rate Limiting
------------------------
-:Valid Range: 0-235 (0=no limit)
-
-The Intel(R) Ethernet Controller XL710 family supports an interrupt rate
-limiting mechanism. The user can control, via ethtool, the number of
-microseconds between interrupts.
-
-Syntax::
-
-  # ethtool -C ethX rx-usecs-high N
-
-The range of 0-235 microseconds provides an effective range of 4,310 to 250,000
-interrupts per second. The value of rx-usecs-high can be set independently of
-rx-usecs and tx-usecs in the same ethtool command, and is also independent of
-the adaptive interrupt moderation algorithm. The underlying hardware supports
-granularity in 4-microsecond intervals, so adjacent values may result in the
-same interrupt rate.
-
-One possible use case is the following::
-
-  # ethtool -C ethX adaptive-rx off adaptive-tx off rx-usecs-high 20 rx-usecs \
-    5 tx-usecs 5
-
-The above command would disable adaptive interrupt moderation, and allow a
-maximum of 5 microseconds before indicating a receive or transmit was complete.
-However, instead of resulting in as many as 200,000 interrupts per second, it
-limits total interrupts per second to 50,000 via the rx-usecs-high parameter.
-
-Performance Optimization
-========================
-Driver defaults are meant to fit a wide variety of workloads, but if further
-optimization is required we recommend experimenting with the following settings.
-
-NOTE: For better performance when processing small (64B) frame sizes, try
-enabling Hyper threading in the BIOS in order to increase the number of logical
-cores in the system and subsequently increase the number of queues available to
-the adapter.
-
-Virtualized Environments
-------------------------
-1. Disable XPS on both ends by using the included virt_perf_default script
-or by running the following command as root::
-
-  for file in `ls /sys/class/net/<ethX>/queues/tx-*/xps_cpus`;
-  do echo 0 > $file; done
-
-2. Using the appropriate mechanism (vcpupin) in the vm, pin the cpu's to
-individual lcpu's, making sure to use a set of cpu's included in the
-device's local_cpulist: /sys/class/net/<ethX>/device/local_cpulist.
-
-3. Configure as many Rx/Tx queues in the VM as available. Do not rely on
-the default setting of 1.
-
-
-Non-virtualized Environments
-----------------------------
-Pin the adapter's IRQs to specific cores by disabling the irqbalance service
-and using the included set_irq_affinity script. Please see the script's help
-text for further options.
-
-- The following settings will distribute the IRQs across all the cores evenly::
-
-  # scripts/set_irq_affinity -x all <interface1> , [ <interface2>, ... ]
-
-- The following settings will distribute the IRQs across all the cores that are
-  local to the adapter (same NUMA node)::
-
-  # scripts/set_irq_affinity -x local <interface1> ,[ <interface2>, ... ]
-
-For very CPU intensive workloads, we recommend pinning the IRQs to all cores.
-
-For IP Forwarding: Disable Adaptive ITR and lower Rx and Tx interrupts per
-queue using ethtool.
-
-- Setting rx-usecs and tx-usecs to 125 will limit interrupts to about 8000
-  interrupts per second per queue.
-
-::
-
-  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 125 \
-    tx-usecs 125
-
-For lower CPU utilization: Disable Adaptive ITR and lower Rx and Tx interrupts
-per queue using ethtool.
-
-- Setting rx-usecs and tx-usecs to 250 will limit interrupts to about 4000
-  interrupts per second per queue.
-
-::
-
-  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 250 \
-    tx-usecs 250
-
-For lower latency: Disable Adaptive ITR and ITR by setting Rx and Tx to 0 using
-ethtool.
-
-::
-
-  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 0 \
-    tx-usecs 0
-
-Application Device Queues (ADq)
--------------------------------
-Application Device Queues (ADq) allows you to dedicate one or more queues to a
-specific application. This can reduce latency for the specified application,
-and allow Tx traffic to be rate limited per application. Follow the steps below
-to set ADq.
-
-1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
-The shaper bw_rlimit parameter is optional.
-
-Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
-to 1Gbit for tc0 and 3Gbit for tc1.
-
-::
-
-  # tc qdisc add dev <interface> root mqprio num_tc 2 map 0 0 0 0 1 1 1 1
-  queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
-  max_rate 1Gbit 3Gbit
-
-map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
-sets priorities 0-3 to use tc0 and 4-7 to use tc1)
-
-queues: for each tc, <num queues>@<offset> (e.g. queues 16@0 16@16 assigns
-16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
-number of queues for all tcs is 64 or number of cores, whichever is lower.)
-
-hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
-offload mode in mqprio that makes full use of the mqprio options, the
-TCs, the queue configurations, and the QoS parameters.
-
-shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
-Totals must be equal or less than port speed.
-
-For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
-monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
-
-2. Enable HW TC offload on interface::
-
-    # ethtool -K <interface> hw-tc-offload on
-
-3. Apply TCs to ingress (RX) flow of interface::
-
-    # tc qdisc add dev <interface> ingress
-
-NOTES:
- - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory.
- - ADq is not compatible with cloud filters.
- - Setting up channels via ethtool (ethtool -L) is not supported when the
-   TCs are configured using mqprio.
- - You must have iproute2 latest version
- - NVM version 6.01 or later is required.
- - ADq cannot be enabled when any the following features are enabled: Data
-   Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband
-   Filters.
- - If another driver (for example, DPDK) has set cloud filters, you cannot
-   enable ADq.
- - Tunnel filters are not supported in ADq. If encapsulated packets do
-   arrive in non-tunnel mode, filtering will be done on the inner headers.
-   For example, for VXLAN traffic in non-tunnel mode, PCTYPE is identified
-   as a VXLAN encapsulated packet, outer headers are ignored. Therefore,
-   inner headers are matched.
- - If a TC filter on a PF matches traffic over a VF (on the PF), that
-   traffic will be routed to the appropriate queue of the PF, and will
-   not be passed on the VF. Such traffic will end up getting dropped higher
-   up in the TCP/IP stack as it does not match PF address data.
- - If traffic matches multiple TC filters that point to different TCs,
-   that traffic will be duplicated and sent to all matching TC queues.
-   The hardware switch mirrors the packet to a VSI list when multiple
-   filters are matched.
-
-
-Known Issues/Troubleshooting
-============================
-
-NOTE: 1 Gb devices based on the Intel(R) Ethernet Network Connection X722 do
-not support the following features:
-
-  * Data Center Bridging (DCB)
-  * QOS
-  * VMQ
-  * SR-IOV
-  * Task Encapsulation offload (VXLAN, NVGRE)
-  * Energy Efficient Ethernet (EEE)
-  * Auto-media detect
-
-Unexpected Issues when the device driver and DPDK share a device
-----------------------------------------------------------------
-Unexpected issues may result when an i40e device is in multi driver mode and
-the kernel driver and DPDK driver are sharing the device. This is because
-access to the global NIC resources is not synchronized between multiple
-drivers. Any change to the global NIC configuration (writing to a global
-register, setting global configuration by AQ, or changing switch modes) will
-affect all ports and drivers on the device. Loading DPDK with the
-"multi-driver" module parameter may mitigate some of the issues.
-
-TC0 must be enabled when setting up DCB on a switch
----------------------------------------------------
-The kernel assumes that TC0 is available, and will disable Priority Flow
-Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
-enabled when setting up DCB on your switch.

-Overview
-========
-
-This file describes the iavf Linux Base Driver. This driver was formerly
-called i40evf.
-
-The iavf driver supports the below mentioned virtual function devices and
-can only be activated on kernels running the i40e or newer Physical Function
-(PF) driver compiled with CONFIG_PCI_IOV.  The iavf driver requires
-CONFIG_PCI_MSI to be enabled.
-
-The guest OS loading the iavf driver must support MSI-X interrupts.
-
-Identifying Your Adapter
-========================
-
-The driver in this kernel is compatible with devices based on the following:
- * Intel(R) XL710 X710 Virtual Function
- * Intel(R) X722 Virtual Function
- * Intel(R) XXV710 Virtual Function
- * Intel(R) Ethernet Adaptive Virtual Function
-
-For the best performance, make sure the latest NVM/FW is installed on your
-device.
-
-For information on how to identify your adapter, and for the latest NVM/FW
-images and Intel network drivers, refer to the Intel Support website:
-http://www.intel.com/support
-
-
-Additional Features and Configurations
-======================================
-
-Viewing Link Messages
----------------------
-Link messages will not be displayed to the console if the distribution is
-restricting system messages. In order to see network driver link messages on
-your console, set dmesg to eight by entering the following::
-
-    # dmesg -n 8
-
-NOTE:
-  This setting is not saved across reboots.
-
-ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information. The latest ethtool
-version is required for this functionality. Download it at:
-https://www.kernel.org/pub/software/network/ethtool/
-
-Setting VLAN Tag Stripping
---------------------------
-If you have applications that require Virtual Functions (VFs) to receive
-packets with VLAN tags, you can disable VLAN tag stripping for the VF. The
-Physical Function (PF) processes requests issued from the VF to enable or
-disable VLAN tag stripping. Note that if the PF has assigned a VLAN to a VF,
-then requests from that VF to set VLAN tag stripping will be ignored.
-
-To enable/disable VLAN tag stripping for a VF, issue the following command
-from inside the VM in which you are running the VF::
-
-    # ethtool -K <if_name> rxvlan on/off
-
-or alternatively::
-
-    # ethtool --offload <if_name> rxvlan on/off
-
-Adaptive Virtual Function
--------------------------
-Adaptive Virtual Function (AVF) allows the virtual function driver, or VF, to
-adapt to changing feature sets of the physical function driver (PF) with which
-it is associated. This allows system administrators to update a PF without
-having to update all the VFs associated with it. All AVFs have a single common
-device ID and branding string.
-
-AVFs have a minimum set of features known as "base mode," but may provide
-additional features depending on what features are available in the PF with
-which the AVF is associated. The following are base mode features:
-
-- 4 Queue Pairs (QP) and associated Configuration Status Registers (CSRs)
-  for Tx/Rx
-- i40e descriptors and ring format
-- Descriptor write-back completion
-- 1 control queue, with i40e descriptors, CSRs and ring format
-- 5 MSI-X interrupt vectors and corresponding i40e CSRs
-- 1 Interrupt Throttle Rate (ITR) index
-- 1 Virtual Station Interface (VSI) per VF
-- 1 Traffic Class (TC), TC0
-- Receive Side Scaling (RSS) with 64 entry indirection table and key,
-  configured through the PF
-- 1 unicast MAC address reserved per VF
-- 16 MAC address filters for each VF
-- Stateless offloads - non-tunneled checksums
-- AVF device ID
-- HW mailbox is used for VF to PF communications (including on Windows)
-
-IEEE 802.1ad (QinQ) Support
----------------------------
-The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
-IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
-"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
-allow L2 tunneling and the ability to segregate traffic within a particular
-VLAN ID, among other uses.
-
-The following are examples of how to configure 802.1ad (QinQ)::
-
-    # ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
-    # ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
-
-Where "24" and "371" are example VLAN IDs.
-
-NOTES:
-  Receive checksum offloads, cloud filters, and VLAN acceleration are not
-  supported for 802.1ad (QinQ) packets.
-
-Application Device Queues (ADq)
--------------------------------
-Application Device Queues (ADq) allows you to dedicate one or more queues to a
-specific application. This can reduce latency for the specified application,
-and allow Tx traffic to be rate limited per application. Follow the steps below
-to set ADq.
-
-Requirements:
-
-- The sch_mqprio, act_mirred and cls_flower modules must be loaded
-- The latest version of iproute2
-- If another driver (for example, DPDK) has set cloud filters, you cannot
-  enable ADQ
-- Depending on the underlying PF device, ADQ cannot be enabled when the
-  following features are enabled:
-
-  + Data Center Bridging (DCB)
-  + Multiple Functions per Port (MFP)
-  + Sideband Filters
-
-1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
-The shaper bw_rlimit parameter is optional.
-
-Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
-to 1Gbit for tc0 and 3Gbit for tc1.
-
-::

-map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
-sets priorities 0-3 to use tc0 and 4-7 to use tc1)
-

-16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
-number of queues for all tcs is 64 or number of cores, whichever is lower.)
-
-hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
-offload mode in mqprio that makes full use of the mqprio options, the
-TCs, the queue configurations, and the QoS parameters.
-
-shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
-Totals must be equal or less than port speed.
-
-For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
-monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
-
-NOTE:
-  Setting up channels via ethtool (ethtool -L) is not supported when the
-  TCs are configured using mqprio.
-
-2. Enable HW TC offload on interface::
-
-    # ethtool -K <interface> hw-tc-offload on
-
-3. Apply TCs to ingress (RX) flow of interface::
-
-    # tc qdisc add dev <interface> ingress
-
-NOTES:
- - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory
- - ADq is not compatible with cloud filters
- - Setting up channels via ethtool (ethtool -L) is not supported when the TCs
-   are configured using mqprio
- - You must have iproute2 latest version
- - NVM version 6.01 or later is required
- - ADq cannot be enabled when any the following features are enabled: Data
-   Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband Filters
- - If another driver (for example, DPDK) has set cloud filters, you cannot
-   enable ADq
- - Tunnel filters are not supported in ADq. If encapsulated packets do arrive
-   in non-tunnel mode, filtering will be done on the inner headers.  For example,
-   for VXLAN traffic in non-tunnel mode, PCTYPE is identified as a VXLAN
-   encapsulated packet, outer headers are ignored. Therefore, inner headers are
-   matched.
- - If a TC filter on a PF matches traffic over a VF (on the PF), that traffic
-   will be routed to the appropriate queue of the PF, and will not be passed on
-   the VF. Such traffic will end up getting dropped higher up in the TCP/IP
-   stack as it does not match PF address data.
- - If traffic matches multiple TC filters that point to different TCs, that
-   traffic will be duplicated and sent to all matching TC queues.  The hardware
-   switch mirrors the packet to a VSI list when multiple filters are matched.
-
-
-Known Issues/Troubleshooting
-============================
-
-Bonding fails with VFs bound to an Intel(R) Ethernet Controller 700 series device
----------------------------------------------------------------------------------
-If you bind Virtual Functions (VFs) to an Intel(R) Ethernet Controller 700
-series based device, the VF slaves may fail when they become the active slave.
-If the MAC address of the VF is set by the PF (Physical Function) of the
-device, when you add a slave, or change the active-backup slave, Linux bonding
-tries to sync the backup slave's MAC address to the same MAC address as the
-active slave. Linux bonding will fail at this point. This issue will not occur
-if the VF's MAC address is not set by the PF.
-
-Traffic Is Not Being Passed Between VM and Client
--------------------------------------------------
-You may not be able to pass traffic between a client system and a
-Virtual Machine (VM) running on a separate host if the Virtual Function
-(VF, or Virtual NIC) is not in trusted mode and spoof checking is enabled
-on the VF. Note that this situation can occur in any combination of client,
-host, and guest operating system. For information on how to set the VF to
-trusted mode, refer to the section "VLAN Tag Packet Steering" in this
-readme document. For information on setting spoof checking, refer to the
-section "MAC and VLAN anti-spoofing feature" in this readme document.
-
-Do not unload port driver if VF with active VM is bound to it
--------------------------------------------------------------
-Do not unload a port's driver if a Virtual Function (VF) with an active Virtual
-Machine (VM) is bound to it. Doing so will cause the port to appear to hang.
-Once the VM shuts down, or otherwise releases the VF, the command will complete.
-
-Using four traffic classes fails
---------------------------------
-Do not try to reserve more than three traffic classes in the iavf driver. Doing
-so will fail to set any traffic classes and will cause the driver to write
-errors to stdout. Use a maximum of three queues to avoid this issue.
-
-Multiple log error messages on iavf driver removal
---------------------------------------------------
-If you have several VFs and you remove the iavf driver, several instances of
-the following log errors are written to the log::
-
-    Unable to send opcode 2 to PF, err I40E_ERR_QUEUE_EMPTY, aq_err ok
-    Unable to send the message to VF 2 aq_err 12
-    ARQ Overflow Error detected
-
-Virtual machine does not get link
----------------------------------
-If the virtual machine has more than one virtual port assigned to it, and those
-virtual ports are bound to different physical ports, you may not get link on
-all of the virtual ports. The following command may work around the issue::
-
-    # ethtool -r <PF>
-
-Where <PF> is the PF interface in the host, for example: p5p1. You may need to
-run the command more than once to get link on all virtual ports.
-
-MAC address of Virtual Function changes unexpectedly
-----------------------------------------------------
-If a Virtual Function's MAC address is not assigned in the host, then the VF
-(virtual function) driver will use a random MAC address. This random MAC
-address may change each time the VF driver is reloaded. You can assign a static
-MAC address in the host machine. This static MAC address will survive
-a VF driver reload.
-
-Driver Buffer Overflow Fix
---------------------------
-The fix to resolve CVE-2016-8105, referenced in Intel SA-00069
-https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00069.html
-is included in this and future versions of the driver.
-
-Multiple Interfaces on Same Ethernet Broadcast Network
-------------------------------------------------------
-Due to the default ARP behavior on Linux, it is not possible to have one system
-on two IP networks in the same Ethernet broadcast domain (non-partitioned
-switch) behave as expected. All Ethernet interfaces will respond to IP traffic
-for any IP address assigned to the system. This results in unbalanced receive
-traffic.
-
-If you have multiple interfaces in a server, either turn on ARP filtering by
-entering::
-
-    # echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
-
-NOTE:
-  This setting is not saved across reboots. The configuration change can be
-  made permanent by adding the following line to the file /etc/sysctl.conf::
-
-    net.ipv4.conf.all.arp_filter = 1
-
-Another alternative is to install the interfaces in separate broadcast domains
-(either in different switches or in a switch partitioned to VLANs).
-
-Rx Page Allocation Errors
--------------------------
-'Page allocation failure. order:0' errors may occur under stress.
-This is caused by the way the Linux kernel reports this stressed condition.

-Identifying Your Adapter
-========================
-For information on how to identify your adapter, and for the latest Intel
-network drivers, refer to the Intel Support website:
-http://www.intel.com/support
-
-
-Command Line Parameters
-========================
-If the driver is built as a module, the following optional parameters are used
-by entering them on the command line with the modprobe command using this
-syntax::
-
-    modprobe igb [<option>=<VAL1>,<VAL2>,...]
-
-There needs to be a <VAL#> for each network port in the system supported by
-this driver. The values will be applied to each instance, in function order.
-For example::
-
-    modprobe igb max_vfs=2,4
-
-In this case, there are two network ports supported by igb in the system.
-
-NOTE: A descriptor describes a data buffer and attributes related to the data
-buffer. This information is accessed by the hardware.
-
-max_vfs
--------
-:Valid Range: 0-7
-
-This parameter adds support for SR-IOV. It causes the driver to spawn up to
-max_vfs worth of virtual functions.  If the value is greater than 0 it will
-also force the VMDq parameter to be 1 or more.
-
-The parameters for the driver are referenced by position. Thus, if you have a
-dual port adapter, or more than one adapter in your system, and want N virtual
-functions per port, you must specify a number for each port with each parameter
-separated by a comma. For example::
-
-    modprobe igb max_vfs=4
-
-This will spawn 4 VFs on the first port.
-
-::
-
-    modprobe igb max_vfs=2,4
-
-This will spawn 2 VFs on the first port and 4 VFs on the second port.
-
-NOTE: Caution must be used in loading the driver with these parameters.
-Depending on your system configuration, number of slots, etc., it is impossible
-to predict in all cases where the positions would be on the command line.
-
-NOTE: Neither the device nor the driver control how VFs are mapped into config
-space. Bus layout will vary by operating system. On operating systems that
-support it, you can check sysfs to find the mapping.
-
-NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
-and VLAN tag stripping/insertion will remain enabled. Please remove the old
-VLAN filter before the new VLAN filter is added. For example::
-
-    ip link set eth0 vf 0 vlan 100	// set vlan 100 for VF 0
-    ip link set eth0 vf 0 vlan 0	// Delete vlan 100
-    ip link set eth0 vf 0 vlan 200	// set a new vlan 200 for VF 0
-
-Debug
------
-:Valid Range: 0-16 (0=none,...,16=all)
-:Default Value: 0
-
-This parameter adjusts the level debug messages displayed in the system logs.
-
-
-Additional Features and Configurations
-======================================
-
-Jumbo Frames
-------------
-Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
-to a value larger than the default value of 1500.
-
-Use the ifconfig command to increase the MTU size. For example, enter the
-following where <x> is the interface number::
-
-    ifconfig eth<x> mtu 9000 up
-
-Alternatively, you can use the ip command as follows::
-
-    ip link set mtu 9000 dev eth<x>
-    ip link set up dev eth<x>
-
-This setting is not saved across reboots. The setting change can be made
-permanent by adding 'MTU=9000' to the file:
-
-- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
-- For SLES: /etc/sysconfig/network/<config_file>
-
-NOTE: The maximum MTU setting for Jumbo Frames is 9216. This value coincides
-with the maximum Jumbo Frames size of 9234 bytes.
-
-NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
-poor performance or loss of link.
-
-
-ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information. The latest ethtool
-version is required for this functionality. Download it at:
-
-https://www.kernel.org/pub/software/network/ethtool/
-
-
-Enabling Wake on LAN (WoL)
---------------------------
-WoL is configured through the ethtool utility.
-
-WoL will be enabled on the system during the next shut down or reboot. For
-this driver version, in order to enable WoL, the igb driver must be loaded
-prior to shutting down or suspending the system.
-
-NOTE: Wake on LAN is only supported on port A of multi-port devices.  Also
-Wake On LAN is not supported for the following device:
-- Intel(R) Gigabit VT Quad Port Server Adapter
-
-
-Multiqueue
-----------
-In this mode, a separate MSI-X vector is allocated for each queue and one for
-"other" interrupts such as link status change and errors. All interrupts are
-throttled via interrupt moderation. Interrupt moderation must be used to avoid
-interrupt storms while the driver is processing one interrupt. The moderation
-value should be at least as large as the expected time for the driver to
-process an interrupt. Multiqueue is off by default.
-
-REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not found,
-the system will fallback to MSI or to Legacy interrupts. This driver supports
-receive multiqueue on all kernels that support MSI-X.
-
-NOTE: On some kernels a reboot is required to switch between single queue mode
-and multiqueue mode or vice-versa.
-
-
-MAC and VLAN anti-spoofing feature
-----------------------------------
-When a malicious driver attempts to send a spoofed packet, it is dropped by the
-hardware and not transmitted.
-
-An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
-spoofed packet is detected, the PF driver will send the following message to
-the system log (displayed by the "dmesg" command):
-Spoof event(s) detected on VF(n), where n = the VF that attempted to do the
-spoofing
-
-
-Setting MAC Address, VLAN and Rate Limit Using IProute2 Tool
-------------------------------------------------------------
-You can set a MAC address of a Virtual Function (VF), a default VLAN and the
-rate limit using the IProute2 tool. Download the latest version of the
-IProute2 tool from Sourceforge if your version does not have all the features
-you require.
-
-Credit Based Shaper (Qav Mode)
-------------------------------
-When enabling the CBS qdisc in the hardware offload mode, traffic shaping using
-the CBS (described in the IEEE 802.1Q-2018 Section 8.6.8.2 and discussed in the
-Annex L) algorithm will run in the i210 controller, so it's more accurate and
-uses less CPU.
-
-When using offloaded CBS, and the traffic rate obeys the configured rate
-(doesn't go above it), CBS should have little to no effect in the latency.
-
-The offloaded version of the algorithm has some limits, caused by how the idle
-slope is expressed in the adapter's registers. It can only represent idle slopes
-in 16.38431 kbps units, which means that if a idle slope of 2576kbps is
-requested, the controller will be configured to use a idle slope of ~2589 kbps,
-because the driver rounds the value up. For more details, see the comments on
-:c:func:`igb_config_tx_modes()`.
-
-NOTE: This feature is exclusive to i210 models.

-=================================================
-
-Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!
-
-Intel wireless LAN adapters are engineered, manufactured, tested, and
-quality checked to ensure that they meet all necessary local and
-governmental regulatory agency requirements for the regions that they
-are designated and/or marked to ship into. Since wireless LANs are
-generally unlicensed devices that share spectrum with radars,
-satellites, and other licensed and unlicensed devices, it is sometimes
-necessary to dynamically detect, avoid, and limit usage to avoid
-interference with these devices. In many instances Intel is required to
-provide test data to prove regional and local compliance to regional and
-governmental regulations before certification or approval to use the
-product is granted. Intel's wireless LAN's EEPROM, firmware, and
-software driver are designed to carefully control parameters that affect
-radio operation and to ensure electromagnetic compliance (EMC). These
-parameters include, without limitation, RF power, spectrum usage,
-channel scanning, and human exposure.
-
-For these reasons Intel cannot permit any manipulation by third parties
-of the software provided in binary format with the wireless WLAN
-adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
-patches, utilities, or code with the Intel wireless LAN adapters that
-have been manipulated by an unauthorized party (i.e., patches,
-utilities, or code (including open source code modifications) which have
-not been validated by Intel), (i) you will be solely responsible for
-ensuring the regulatory compliance of the products, (ii) Intel will bear
-no liability, under any theory of liability for any issues associated
-with the modified products, including without limitation, claims under
-the warranty and/or issues arising from regulatory non-compliance, and
-(iii) Intel will not provide or be required to assist in providing
-support to any third parties for such modified products.
-
-Note: Many regulatory agencies consider Wireless LAN adapters to be
-modules, and accordingly, condition system-level regulatory approval
-upon receipt and review of test data documenting that the antennas and
-system configuration do not cause the EMC and radio operation to be
-non-compliant.
-
-The drivers available for download from SourceForge are provided as a
-part of a development project.  Conformance to local regulatory
-requirements is the responsibility of the individual developer.  As
-such, if you are interested in deploying or shipping a driver as part of
-solution intended to be used for purposes other than development, please
-obtain a tested driver from Intel Customer Support at:
-
-http://www.intel.com/support/wireless/sb/CS-006408.htm
-
-1. Introduction
-===============
-
-This document provides a brief overview of the features supported by the
-IPW2100 driver project.  The main project website, where the latest
-development version of the driver can be found, is:
-
-	http://ipw2100.sourceforge.net
-
-There you can find the not only the latest releases, but also information about
-potential fixes and patches, as well as links to the development mailing list
-for the driver project.
-
-
-2. Release git-1.1.5 Current Supported Features
-===============================================
-
-- Managed (BSS) and Ad-Hoc (IBSS)
-- WEP (shared key and open)
-- Wireless Tools support
-- 802.1x (tested with XSupplicant 1.0.1)
-
-Enabled (but not supported) features:
-- Monitor/RFMon mode
-- WPA/WPA2
-
-The distinction between officially supported and enabled is a reflection
-on the amount of validation and interoperability testing that has been
-performed on a given feature.
-
-
-3. Command Line Parameters
-==========================
-
-If the driver is built as a module, the following optional parameters are used
-by entering them on the command line with the modprobe command using this
-syntax::
-
-	modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
-
-For example, to disable the radio on driver loading, enter:
-
-	modprobe ipw2100 disable=1
-
-The ipw2100 driver supports the following module parameters:
-
-=========	==============	============  ==============================
-Name		Value		Example       Meaning
-=========	==============	============  ==============================
-debug		0x0-0xffffffff	debug=1024    Debug level set to 1024
-mode		0,1,2		mode=1        AdHoc
-channel		int		channel=3     Only valid in AdHoc or Monitor
-associate	boolean		associate=0   Do NOT auto associate
-disable		boolean		disable=1     Do not power the HW
-=========	==============	============  ==============================
-
-
-4. Sysfs Helper Files
-=====================
-
-There are several ways to control the behavior of the driver.  Many of the
-general capabilities are exposed through the Wireless Tools (iwconfig).  There
-are a few capabilities that are exposed through entries in the Linux Sysfs.
-
-
-**Driver Level**
-
-For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
-
-  debug_level
-	This controls the same global as the 'debug' module parameter.  For
-	information on the various debugging levels available, run the 'dvals'
-	script found in the driver source directory.
-
-	.. note::
-
-	      'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn on.
-
-**Device Level**
-
-For the device level files look in::
-
-	/sys/bus/pci/drivers/ipw2100/{PCI-ID}/
-
-For example::
-
-	/sys/bus/pci/drivers/ipw2100/0000:02:01.0
-
-For the device level files, see /sys/bus/pci/drivers/ipw2100:
-
-  rf_kill
-	read
-
-	==  =========================================
-	0   RF kill not enabled (radio on)
-	1   SW based RF kill active (radio off)
-	2   HW based RF kill active (radio off)
-	3   Both HW and SW RF kill active (radio off)
-	==  =========================================
-
-	write
-
-	==  ==================================================
-	0   If SW based RF kill active, turn the radio back on
-	1   If radio is on, activate SW based RF kill
-	==  ==================================================
-
-	.. note::
-
-	   If you enable the SW based RF kill and then toggle the HW
-	   based RF kill from ON -> OFF -> ON, the radio will NOT come back on
-
-
-5. Radio Kill Switch
-====================
-
-Most laptops provide the ability for the user to physically disable the radio.
-Some vendors have implemented this as a physical switch that requires no
-software to turn the radio off and on.  On other laptops, however, the switch
-is controlled through a button being pressed and a software driver then making
-calls to turn the radio off and on.  This is referred to as a "software based
-RF kill switch"
-
-See the Sysfs helper file 'rf_kill' for determining the state of the RF switch
-on your system.
-
-
-6. Dynamic Firmware
-===================
-
-As the firmware is licensed under a restricted use license, it can not be
-included within the kernel sources.  To enable the IPW2100 you will need a
-firmware image to load into the wireless NIC's processors.
-
-You can obtain these images from <http://ipw2100.sf.net/firmware.php>.
-
-See INSTALL for instructions on installing the firmware.
-
-
-7. Power Management
-===================
-
-The IPW2100 supports the configuration of the Power Save Protocol
-through a private wireless extension interface.  The IPW2100 supports
-the following different modes:
-
-	===	===========================================================
-	off	No power management.  Radio is always on.
-	on	Automatic power management
-	1-5	Different levels of power management.  The higher the
-		number the greater the power savings, but with an impact to
-		packet latencies.
-	===	===========================================================
-
-Power management works by powering down the radio after a certain
-interval of time has passed where no packets are passed through the
-radio.  Once powered down, the radio remains in that state for a given
-period of time.  For higher power savings, the interval between last
-packet processed to sleep is shorter and the sleep period is longer.
-
-When the radio is asleep, the access point sending data to the station
-must buffer packets at the AP until the station wakes up and requests
-any buffered packets.  If you have an AP that does not correctly support
-the PSP protocol you may experience packet loss or very poor performance
-while power management is enabled.  If this is the case, you will need
-to try and find a firmware update for your AP, or disable power
-management (via ``iwconfig eth1 power off``)
-
-To configure the power level on the IPW2100 you use a combination of
-iwconfig and iwpriv.  iwconfig is used to turn power management on, off,
-and set it to auto.
-
-	=========================  ====================================
-	iwconfig eth1 power off    Disables radio power down
-	iwconfig eth1 power on     Enables radio power management to
-				   last set level (defaults to AUTO)
-	iwpriv eth1 set_power 0    Sets power level to AUTO and enables
-				   power management if not previously
-				   enabled.
-	iwpriv eth1 set_power 1-5  Set the power level as specified,
-				   enabling power management if not
-				   previously enabled.
-	=========================  ====================================
-
-You can view the current power level setting via::
-
-	iwpriv eth1 get_power
-
-It will return the current period or timeout that is configured as a string
-in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
-time after packet processing), yyyy is the period to sleep (amount of time to
-wait before powering the radio and querying the access point for buffered
-packets), and z is the 'power level'.  If power management is turned off the
-xxxx/yyyy will be replaced with 'off' -- the level reported will be the active
-level if `iwconfig eth1 power on` is invoked.

-0. IMPORTANT INFORMATION BEFORE USING THIS DRIVER
-=================================================
-
-Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!
-
-Intel wireless LAN adapters are engineered, manufactured, tested, and
-quality checked to ensure that they meet all necessary local and
-governmental regulatory agency requirements for the regions that they
-are designated and/or marked to ship into. Since wireless LANs are
-generally unlicensed devices that share spectrum with radars,
-satellites, and other licensed and unlicensed devices, it is sometimes
-necessary to dynamically detect, avoid, and limit usage to avoid
-interference with these devices. In many instances Intel is required to
-provide test data to prove regional and local compliance to regional and
-governmental regulations before certification or approval to use the
-product is granted. Intel's wireless LAN's EEPROM, firmware, and
-software driver are designed to carefully control parameters that affect
-radio operation and to ensure electromagnetic compliance (EMC). These
-parameters include, without limitation, RF power, spectrum usage,
-channel scanning, and human exposure.
-
-For these reasons Intel cannot permit any manipulation by third parties
-of the software provided in binary format with the wireless WLAN
-adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
-patches, utilities, or code with the Intel wireless LAN adapters that
-have been manipulated by an unauthorized party (i.e., patches,
-utilities, or code (including open source code modifications) which have
-not been validated by Intel), (i) you will be solely responsible for
-ensuring the regulatory compliance of the products, (ii) Intel will bear
-no liability, under any theory of liability for any issues associated
-with the modified products, including without limitation, claims under
-the warranty and/or issues arising from regulatory non-compliance, and
-(iii) Intel will not provide or be required to assist in providing
-support to any third parties for such modified products.
-
-Note: Many regulatory agencies consider Wireless LAN adapters to be
-modules, and accordingly, condition system-level regulatory approval
-upon receipt and review of test data documenting that the antennas and
-system configuration do not cause the EMC and radio operation to be
-non-compliant.
-
-The drivers available for download from SourceForge are provided as a
-part of a development project.  Conformance to local regulatory
-requirements is the responsibility of the individual developer.  As
-such, if you are interested in deploying or shipping a driver as part of
-solution intended to be used for purposes other than development, please
-obtain a tested driver from Intel Customer Support at:
-
-http://support.intel.com

-
-1. Introduction
-===============
-
-The following sections attempt to provide a brief introduction to using
-the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
-
-This document is not meant to be a comprehensive manual on
-understanding or using wireless technologies, but should be sufficient
-to get you moving without wires on Linux.
-
-For information on building and installing the driver, see the INSTALL
-file.
-
-
-1.1. Overview of Features
--------------------------
-The current release (1.1.2) supports the following features:
-
-+ BSS mode (Infrastructure, Managed)
-+ IBSS mode (Ad-Hoc)
-+ WEP (OPEN and SHARED KEY mode)
-+ 802.1x EAP via wpa_supplicant and xsupplicant
-+ Wireless Extension support
-+ Full B and G rate support (2200 and 2915)
-+ Full A rate support (2915 only)
-+ Transmit power control
-+ S state support (ACPI suspend/resume)
-
-The following features are currently enabled, but not officially
-supported:
-
-+ WPA
-+ long/short preamble support
-+ Monitor mode (aka RFMon)
-
-The distinction between officially supported and enabled is a reflection
-on the amount of validation and interoperability testing that has been
-performed on a given feature.
-
-
-
-1.2. Command Line Parameters
-----------------------------
-
-Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless
-2915ABG Driver for Linux allows configuration options to be provided
-as module parameters.  The most common way to specify a module parameter
-is via the command line.
-
-The general form is::
-
-    % modprobe ipw2200 parameter=value
-
-Where the supported parameter are:
-
-  associate
-	Set to 0 to disable the auto scan-and-associate functionality of the
-	driver.  If disabled, the driver will not attempt to scan
-	for and associate to a network until it has been configured with
-	one or more properties for the target network, for example configuring
-	the network SSID.  Default is 0 (do not auto-associate)
-
-	Example: % modprobe ipw2200 associate=0
-
-  auto_create
-	Set to 0 to disable the auto creation of an Ad-Hoc network
-	matching the channel and network name parameters provided.
-	Default is 1.
-
-  channel
-	channel number for association.  The normal method for setting
-	the channel would be to use the standard wireless tools
-	(i.e. `iwconfig eth1 channel 10`), but it is useful sometimes
-	to set this while debugging.  Channel 0 means 'ANY'
-
-  debug
-	If using a debug build, this is used to control the amount of debug
-	info is logged.  See the 'dvals' and 'load' script for more info on
-	how to use this (the dvals and load scripts are provided as part
-	of the ipw2200 development snapshot releases available from the
-	SourceForge project at http://ipw2200.sf.net)
-
-  led
-	Can be used to turn on experimental LED code.
-	0 = Off, 1 = On.  Default is 1.
-
-  mode
-	Can be used to set the default mode of the adapter.
-	0 = Managed, 1 = Ad-Hoc, 2 = Monitor
-
-
-1.3. Wireless Extension Private Methods
----------------------------------------
-
-As an interface designed to handle generic hardware, there are certain
-capabilities not exposed through the normal Wireless Tool interface.  As
-such, a provision is provided for a driver to declare custom, or
-private, methods.  The Intel(R) PRO/Wireless 2915ABG Driver for Linux
-defines several of these to configure various settings.
-
-The general form of using the private wireless methods is::
-
-	% iwpriv $IFNAME method parameters
-
-Where $IFNAME is the interface name the device is registered with
-(typically eth1, customized via one of the various network interface
-name managers, such as ifrename)
-
-The supported private methods are:
-
-  get_mode
-	Can be used to report out which IEEE mode the driver is
-	configured to support.  Example:
-
-	% iwpriv eth1 get_mode
-	eth1	get_mode:802.11bg (6)
-
-  set_mode
-	Can be used to configure which IEEE mode the driver will
-	support.
-
-	Usage::
-
-	    % iwpriv eth1 set_mode {mode}
-
-	Where {mode} is a number in the range 1-7:
-
-	==	=====================
-	1	802.11a (2915 only)
-	2	802.11b
-	3	802.11ab (2915 only)
-	4	802.11g
-	5	802.11ag (2915 only)
-	6	802.11bg
-	7	802.11abg (2915 only)
-	==	=====================
-
-  get_preamble
-	Can be used to report configuration of preamble length.
-
-  set_preamble
-	Can be used to set the configuration of preamble length:
-
-	Usage::
-
-	    % iwpriv eth1 set_preamble {mode}
-
-	Where {mode} is one of:
-
-	==	========================================
-	1	Long preamble only
-	0	Auto (long or short based on connection)
-	==	========================================
-
-
-1.4. Sysfs Helper Files
------------------------
-
-The Linux kernel provides a pseudo file system that can be used to
-access various components of the operating system.  The Intel(R)
-PRO/Wireless 2915ABG Driver for Linux exposes several configuration
-parameters through this mechanism.
-
-An entry in the sysfs can support reading and/or writing.  You can
-typically query the contents of a sysfs entry through the use of cat,
-and can set the contents via echo.  For example::
-
-    % cat /sys/bus/pci/drivers/ipw2200/debug_level
-
-Will report the current debug level of the driver's logging subsystem
-(only available if CONFIG_IPW2200_DEBUG was configured when the driver
-was built).
-
-You can set the debug level via::
-
-    % echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
-
-Where $VALUE would be a number in the case of this sysfs entry.  The
-input to sysfs files does not have to be a number.  For example, the
-firmware loader used by hotplug utilizes sysfs entries for transferring
-the firmware image from user space into the driver.
-
-The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries
-at two levels -- driver level, which apply to all instances of the driver
-(in the event that there are more than one device installed) and device
-level, which applies only to the single specific instance.
-
-
-1.4.1 Driver Level Sysfs Helper Files
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
-
-  debug_level
-	This controls the same global as the 'debug' module parameter
-
-
-
-1.4.2 Device Level Sysfs Helper Files
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-For the device level files, look in::
-
-	/sys/bus/pci/drivers/ipw2200/{PCI-ID}/
-
-For example:::
-
-	/sys/bus/pci/drivers/ipw2200/0000:02:01.0
-
-For the device level files, see /sys/bus/pci/drivers/ipw2200:
-
-  rf_kill
-	read -
-
-	==  =========================================
-	0   RF kill not enabled (radio on)
-	1   SW based RF kill active (radio off)
-	2   HW based RF kill active (radio off)
-	3   Both HW and SW RF kill active (radio off)
-	==  =========================================
-
-	write -
-
-	==  ==================================================
-	0   If SW based RF kill active, turn the radio back on
-	1   If radio is on, activate SW based RF kill
-	==  ==================================================
-
-	.. note::
-
-	   If you enable the SW based RF kill and then toggle the HW
-	   based RF kill from ON -> OFF -> ON, the radio will NOT come back on
-
-  ucode
-	read-only access to the ucode version number
-
-  led
-	read -
-
-	==  =================
-	0   LED code disabled
-	1   LED code enabled
-	==  =================
-
-	write -
-
-	==  ================
-	0   Disable LED code
-	1   Enable LED code
-	==  ================
-
-
-	.. note::
-
-	   The LED code has been reported to hang some systems when
-	   running ifconfig and is therefore disabled by default.
-
-
-1.5. Supported channels
------------------------
-
-Upon loading the Intel(R) PRO/Wireless 2915ABG Driver for Linux, a
-message stating the detected geography code and the number of 802.11
-channels supported by the card will be displayed in the log.
-
-The geography code corresponds to a regulatory domain as shown in the
-table below.
-
-	+------+----------------------------+--------------------+
-	|      |			    | Supported channels |
-	| Code |        Geography	    +----------+---------+

-	+------+----------------------------+----------+---------+
-
-2.  Ad-Hoc Networking
-=====================
-
-When using a device in an Ad-Hoc network, it is useful to understand the
-sequence and requirements for the driver to be able to create, join, or
-merge networks.
-
-The following attempts to provide enough information so that you can
-have a consistent experience while using the driver as a member of an
-Ad-Hoc network.
-
-2.1. Joining an Ad-Hoc Network
-------------------------------
-
-The easiest way to get onto an Ad-Hoc network is to join one that
-already exists.
-
-2.2. Creating an Ad-Hoc Network
--------------------------------
-
-An Ad-Hoc networks is created using the syntax of the Wireless tool.
-
-For Example:
-iwconfig eth1 mode ad-hoc essid testing channel 2
-
-2.3. Merging Ad-Hoc Networks
-----------------------------
-
-
-3. Interaction with Wireless Tools
-==================================
-
-3.1 iwconfig mode
------------------
-
-When configuring the mode of the adapter, all run-time configured parameters
-are reset to the value used when the module was loaded.  This includes
-channels, rates, ESSID, etc.
-
-3.2 iwconfig sens
------------------
-
-The 'iwconfig ethX sens XX' command will not set the signal sensitivity
-threshold, as described in iwconfig documentation, but rather the number
-of consecutive missed beacons that will trigger handover, i.e. roaming
-to another access point. At the same time, it will set the disassociation
-threshold to 3 times the given value.
-
-
-4.  About the Version Numbers
-=============================
-
-Due to the nature of open source development projects, there are
-frequently changes being incorporated that have not gone through
-a complete validation process.  These changes are incorporated into
-development snapshot releases.
-
-Releases are numbered with a three level scheme:
-
-	major.minor.development
-
-Any version where the 'development' portion is 0 (for example
-1.0.0, 1.1.0, etc.) indicates a stable version that will be made
-available for kernel inclusion.
-
-Any version where the 'development' portion is not a 0 (for
-example 1.0.1, 1.1.5, etc.) indicates a development version that is
-being made available for testing and cutting edge users.  The stability
-and functionality of the development releases are not know.  We make
-efforts to try and keep all snapshots reasonably stable, but due to the
-frequency of their release, and the desire to get those releases
-available as quickly as possible, unknown anomalies should be expected.
-
-The major version number will be incremented when significant changes
-are made to the driver.  Currently, there are no major changes planned.
-
-5. Firmware installation
-========================
-
-The driver requires a firmware image, download it and extract the
-files under /lib/firmware (or wherever your hotplug's firmware.agent
-will look for firmware files)
-
-The firmware can be downloaded from the following URL:
-
-    http://ipw2200.sf.net/
-

-For more information on how to identify your adapter, go to the Adapter &
-Driver ID Guide at:
-
-    https://support.intel.com
-
-
-Command Line Parameters
-=======================
-
-If the driver is built as a module, the  following optional parameters are
-used by entering them on the command line with the modprobe command using
-this syntax::
-
-    modprobe ixgb [<option>=<VAL1>,<VAL2>,...]
-
-For example, with two 10GbE PCI adapters, entering::
-
-    modprobe ixgb TxDescriptors=80,128
-
-loads the ixgb driver with 80 TX resources for the first adapter and 128 TX
-resources for the second adapter.
-
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-Copybreak
----------
-:Valid Range: 0-XXXX
-:Default Value: 256
-
-    This is the maximum size of packet that is copied to a new buffer on
-    receive.
-
-Debug
------
-:Valid Range: 0-16 (0=none,...,16=all)
-:Default Value: 0
-
-    This parameter adjusts the level of debug messages displayed in the
-    system logs.
-
-FlowControl
------------
-:Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
-:Default Value: 1 if no EEPROM, otherwise read from EEPROM
-
-    This parameter controls the automatic generation(Tx) and response(Rx) to
-    Ethernet PAUSE frames.  There are hardware bugs associated with enabling
-    Tx flow control so beware.
-
-RxDescriptors
--------------
-:Valid Range: 64-4096
-:Default Value: 1024
-
-    This value is the number of receive descriptors allocated by the driver.
-    Increasing this value allows the driver to buffer more incoming packets.
-    Each descriptor is 16 bytes.  A receive buffer is also allocated for
-    each descriptor and can be either 2048, 4056, 8192, or 16384 bytes,
-    depending on the MTU setting.  When the MTU size is 1500 or less, the
-    receive buffer size is 2048 bytes. When the MTU is greater than 1500 the
-    receive buffer size will be either 4056, 8192, or 16384 bytes.  The
-    maximum MTU size is 16114.
-
-TxDescriptors
--------------
-:Valid Range: 64-4096
-:Default Value: 256
-
-    This value is the number of transmit descriptors allocated by the driver.
-    Increasing this value allows the driver to queue more transmits.  Each
-    descriptor is 16 bytes.
-
-RxIntDelay
-----------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 72
-
-    This value delays the generation of receive interrupts in units of
-    0.8192 microseconds.  Receive interrupt reduction can improve CPU
-    efficiency if properly tuned for specific network traffic.  Increasing
-    this value adds extra latency to frame reception and can end up
-    decreasing the throughput of TCP traffic.  If the system is reporting
-    dropped receives, this value may be set too high, causing the driver to
-    run out of available receive descriptors.
-
-TxIntDelay
-----------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 32
-
-    This value delays the generation of transmit interrupts in units of
-    0.8192 microseconds.  Transmit interrupt reduction can improve CPU
-    efficiency if properly tuned for specific network traffic.  Increasing
-    this value adds extra latency to frame transmission and can end up
-    decreasing the throughput of TCP traffic.  If this value is set too high,
-    it will cause the driver to run out of available transmit descriptors.
-
-XsumRX
-------
-:Valid Range: 0-1
-:Default Value: 1
-
-    A value of '1' indicates that the driver should enable IP checksum
-    offload for received packets (both UDP and TCP) to the adapter hardware.
-
-RxFCHighThresh
---------------
-:Valid Range: 1,536-262,136 (0x600 - 0x3FFF8, 8 byte granularity)
-:Default Value: 196,608 (0x30000)
-
-    Receive Flow control high threshold (when we send a pause frame)
-
-RxFCLowThresh
--------------
-:Valid Range: 64-262,136 (0x40 - 0x3FFF8, 8 byte granularity)
-:Default Value: 163,840 (0x28000)
-
-    Receive Flow control low threshold (when we send a resume frame)
-
-FCReqTimeout
-------------
-:Valid Range: 1-65535
-:Default Value: 65535
-
-    Flow control request timeout (how long to pause the link partner's tx)
-
-IntDelayEnable
---------------
-:Value Range: 0,1
-:Default Value: 1
-
-    Interrupt Delay, 0 disables transmit interrupt delay and 1 enables it.
-
-
-Improving Performance
-=====================
-
-With the 10 Gigabit server adapters, the default Linux configuration will
-very likely limit the total available throughput artificially.  There is a set
-of configuration changes that, when applied together, will increase the ability
-of Linux to transmit and receive data.  The following enhancements were
-originally acquired from settings published at http://www.spec.org/web99/ for
-various submitted results using Linux.
-
-NOTE:
-  These changes are only suggestions, and serve as a starting point for
-  tuning your network performance.
-
-The changes are made in three major ways, listed in order of greatest effect:
-
-- Use ip link to modify the mtu (maximum transmission unit) and the txqueuelen
-  parameter.
-- Use sysctl to modify /proc parameters (essentially kernel tuning)
-- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
-  transmit burst lengths on the bus.
-
-NOTE:
-  setpci modifies the adapter's configuration registers to allow it to read
-  up to 4k bytes at a time (for transmits).  However, for some systems the
-  behavior after modifying this register may be undefined (possibly errors of
-  some kind).  A power-cycle, hard reset or explicitly setting the e6 register
-  back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a
-  stable configuration.
-
-- COPY these lines and paste them into ixgb_perf.sh:
-
-::
-
-  #!/bin/bash
-  echo "configuring network performance , edit this file to change the interface
-  or device ID of 10GbE card"
-  # set mmrbc to 4k reads, modify only Intel 10GbE device IDs
-  # replace 1a48 with appropriate 10GbE device's ID installed on the system,
-  # if needed.
-  setpci -d 8086:1a48 e6.b=2e
-  # set the MTU (max transmission unit) - it requires your switch and clients
-  # to change as well.
-  # set the txqueuelen
-  # your ixgb adapter should be loaded as eth1 for this to work, change if needed
-  ip li set dev eth1 mtu 9000 txqueuelen 1000 up
-  # call the sysctl utility to modify /proc/sys entries
-  sysctl -p ./sysctl_ixgb.conf
-
-- COPY these lines and paste them into sysctl_ixgb.conf:
-
-::
-
-  # some of the defaults may be different for your kernel
-  # call this file with sysctl -p <this file>
-  # these are just suggested values that worked well to increase throughput in
-  # several network benchmark tests, your mileage may vary
-
-  ### IPV4 specific settings
-  # turn TCP timestamp support off, default 1, reduces CPU use
-  net.ipv4.tcp_timestamps = 0
-  # turn SACK support off, default on
-  # on systems with a VERY fast bus -> memory interface this is the big gainer
-  net.ipv4.tcp_sack = 0
-  # set min/default/max TCP read buffer, default 4096 87380 174760
-  net.ipv4.tcp_rmem = 10000000 10000000 10000000
-  # set min/pressure/max TCP write buffer, default 4096 16384 131072
-  net.ipv4.tcp_wmem = 10000000 10000000 10000000
-  # set min/pressure/max TCP buffer space, default 31744 32256 32768
-  net.ipv4.tcp_mem = 10000000 10000000 10000000
-
-  ### CORE settings (mostly for socket and UDP effect)
-  # set maximum receive socket buffer size, default 131071
-  net.core.rmem_max = 524287
-  # set maximum send socket buffer size, default 131071
-  net.core.wmem_max = 524287
-  # set default receive socket buffer size, default 65535
-  net.core.rmem_default = 524287
-  # set default send socket buffer size, default 65535
-  net.core.wmem_default = 524287
-  # set maximum amount of option memory buffers, default 10240
-  net.core.optmem_max = 524287
-  # set number of unprocessed input packets before kernel starts dropping them; default 300
-  net.core.netdev_max_backlog = 300000
-
-Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface
-your ixgb driver is using and/or replace '1a48' with appropriate 10GbE device's
-ID installed on the system.
-
-NOTE:
-  Unless these scripts are added to the boot process, these changes will
-  only last only until the next system reboot.
-
-
-Resolving Slow UDP Traffic
---------------------------
-If your server does not seem to be able to receive UDP traffic as fast as it
-can receive TCP traffic, it could be because Linux, by default, does not set
-the network stack buffers as large as they need to be to support high UDP
-transfer rates.  One way to alleviate this problem is to allow more memory to
-be used by the IP stack to store incoming data.
-
-For instance, use the commands::
-
-    sysctl -w net.core.rmem_max=262143
-
-and::
-
-    sysctl -w net.core.rmem_default=262143
-
-to increase the read buffer memory max and default to 262143 (256k - 1) from
-defaults of max=131071 (128k - 1) and default=65535 (64k - 1).  These variables
-will increase the amount of memory used by the network stack for receives, and
-can be increased significantly more if necessary for your application.
-
-
-Additional Configurations
-=========================
-
-Configuring the Driver on Different Distributions
--------------------------------------------------
-Configuring a network driver to load properly when the system is started is
-distribution dependent. Typically, the configuration process involves adding
-an alias line to /etc/modprobe.conf as well as editing other system startup
-scripts and/or configuration files.  Many popular Linux distributions ship
-with tools to make these changes for you.  To learn the proper way to
-configure a network device for your system, refer to your distribution
-documentation.  If during this process you are asked for the driver or module
-name, the name for the Linux Base Driver for the Intel 10GbE Family of
-Adapters is ixgb.
-
-Viewing Link Messages
----------------------
-Link messages will not be displayed to the console if the distribution is
-restricting system messages. In order to see network driver link messages on
-your console, set dmesg to eight by entering the following::
-
-    dmesg -n 8
-
-NOTE: This setting is not saved across reboots.
-
-Jumbo Frames
-------------
-The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
-enabled by changing the MTU to a value larger than the default of 1500.
-The maximum value for the MTU is 16114.  Use the ip command to
-increase the MTU size.  For example::
-
-    ip li set dev ethx mtu 9000
-
-The maximum MTU setting for Jumbo Frames is 16114.  This value coincides
-with the maximum Jumbo Frames size of 16128.
-
-Ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information.  The ethtool
-version 1.6 or later is required for this functionality.
-
-The latest release of ethtool can be found from
-https://www.kernel.org/pub/software/network/ethtool/
-
-NOTE:
-  The ethtool version 1.6 only supports a limited set of ethtool options.
-  Support for a more complete ethtool feature set can be enabled by
-  upgrading to the latest version.
-
-NAPI
-----
-NAPI (Rx polling mode) is supported in the ixgb driver.
-
-See https://wiki.linuxfoundation.org/networking/napi for more information on
-NAPI.
-
-
-Known Issues/Troubleshooting
-============================
-
-NOTE:
-  After installing the driver, if your Intel Network Connection is not
-  working, verify in the "In This Release" section of the readme that you have
-  installed the correct driver.
-
-Cable Interoperability Issue with Fujitsu XENPAK Module in SmartBits Chassis
-----------------------------------------------------------------------------
-Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
-Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
-chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
-The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
-Server adapter or the SmartBits. If this situation occurs using a different
-cable assembly may resolve the issue.
-
-Cable Interoperability Issues with HP Procurve 3400cl Switch Port
------------------------------------------------------------------
-Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
-adapter is connected to an HP Procurve 3400cl switch port using short cables
-(1 m or shorter). If this situation occurs, using a longer cable may resolve
-the issue.
-
-Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
-Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
-errors may be received either by the CX4 Server adapter or at the switch. If
-this situation occurs, using a different cable assembly may resolve the issue.
-
-Jumbo Frames System Requirement
--------------------------------
-Memory allocation failures have been observed on Linux systems with 64 MB
-of RAM or less that are running Jumbo Frames.  If you are using Jumbo
-Frames, your system may require more than the advertised minimum
-requirement of 64 MB of system memory.
-
-Performance Degradation with Jumbo Frames
------------------------------------------
-Degradation in throughput performance may be observed in some Jumbo frames
-environments.  If this is observed, increasing the application's socket buffer
-size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
-See the specific application manual and /usr/src/linux*/Documentation/
-networking/ip-sysctl.txt for more details.
-
-Allocating Rx Buffers when Using Jumbo Frames
----------------------------------------------
-Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
-the available memory is heavily fragmented. This issue may be seen with PCI-X
-adapters or with packet split disabled. This can be reduced or eliminated
-by changing the amount of available memory for receive buffer allocation, by
-increasing /proc/sys/vm/min_free_kbytes.
-
-Multiple Interfaces on Same Ethernet Broadcast Network
-------------------------------------------------------
-Due to the default ARP behavior on Linux, it is not possible to have
-one system on two IP networks in the same Ethernet broadcast domain
-(non-partitioned switch) behave as expected.  All Ethernet interfaces
-will respond to IP traffic for any IP address assigned to the system.
-This results in unbalanced receive traffic.
-
-If you have multiple interfaces in a server, do either of the following:
-
-  - Turn on ARP filtering by entering::
-
-      echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
-
-  - Install the interfaces in separate broadcast domains - either in
-    different switches or in a switch partitioned to VLANs.
-
-UDP Stress Test Dropped Packet Issue
---------------------------------------
-Under small packets UDP stress test with 10GbE driver, the Linux system
-may drop UDP packets due to the fullness of socket buffers. You may want
-to change the driver's Flow Control variables to the minimum value for
-controlling packet reception.
-
-Tx Hangs Possible Under Stress
-------------------------------
-Under stress conditions, if TX hangs occur, turning off TSO
-"ethtool -K eth0 tso off" may resolve the problem.

-a different type of module, the driver will not load.
-- Hot Swapping/hot plugging optical modules is not supported.
-- Only single speed, 10 gigabit modules are supported.
-- LAN on Motherboard (LOMs) may support DA, SR, or LR modules. Other module
-types are not supported. Please see your system documentation for details.

-
-Command Line Parameters
-=======================
-
-max_vfs
--------
-:Valid Range: 1-63
-
-This parameter adds support for SR-IOV. It causes the driver to spawn up to
-max_vfs worth of virtual functions.
-If the value is greater than 0 it will also force the VMDq parameter to be 1 or
-more.
-
-NOTE: This parameter is only used on kernel 3.7.x and below. On kernel 3.8.x
-and above, use sysfs to enable VFs. Also, for Red Hat distributions, this
-parameter is only used on version 6.6 and older. For version 6.7 and newer, use
-sysfs. For example::
-
-  #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs // enable VFs
-  #echo 0 > /sys/class/net/$dev/device/sriov_numvfs               //disable VFs
-
-The parameters for the driver are referenced by position. Thus, if you have a
-dual port adapter, or more than one adapter in your system, and want N virtual
-functions per port, you must specify a number for each port with each parameter
-separated by a comma. For example::
-
-  modprobe ixgbe max_vfs=4
-
-This will spawn 4 VFs on the first port.
-
-::
-
-  modprobe ixgbe max_vfs=2,4
-
-This will spawn 2 VFs on the first port and 4 VFs on the second port.
-
-NOTE: Caution must be used in loading the driver with these parameters.
-Depending on your system configuration, number of slots, etc., it is impossible
-to predict in all cases where the positions would be on the command line.
-
-NOTE: Neither the device nor the driver control how VFs are mapped into config
-space. Bus layout will vary by operating system. On operating systems that
-support it, you can check sysfs to find the mapping.
-
-NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
-and VLAN tag stripping/insertion will remain enabled. Please remove the old
-VLAN filter before the new VLAN filter is added. For example,
-
-::
-
-  ip link set eth0 vf 0 vlan 100 // set VLAN 100 for VF 0
-  ip link set eth0 vf 0 vlan 0   // Delete VLAN 100
-  ip link set eth0 vf 0 vlan 200 // set a new VLAN 200 for VF 0
-
-With kernel 3.6, the driver supports the simultaneous usage of max_vfs and DCB
-features, subject to the constraints described below. Prior to kernel 3.6, the
-driver did not support the simultaneous operation of max_vfs greater than 0 and
-the DCB features (multiple traffic classes utilizing Priority Flow Control and
-Extended Transmission Selection).
-
-When DCB is enabled, network traffic is transmitted and received through
-multiple traffic classes (packet buffers in the NIC). The traffic is associated
-with a specific class based on priority, which has a value of 0 through 7 used
-in the VLAN tag. When SR-IOV is not enabled, each traffic class is associated
-with a set of receive/transmit descriptor queue pairs. The number of queue
-pairs for a given traffic class depends on the hardware configuration. When
-SR-IOV is enabled, the descriptor queue pairs are grouped into pools. The
-Physical Function (PF) and each Virtual Function (VF) is allocated a pool of
-receive/transmit descriptor queue pairs. When multiple traffic classes are
-configured (for example, DCB is enabled), each pool contains a queue pair from
-each traffic class. When a single traffic class is configured in the hardware,
-the pools contain multiple queue pairs from the single traffic class.
-
-The number of VFs that can be allocated depends on the number of traffic
-classes that can be enabled. The configurable number of traffic classes for
-each enabled VF is as follows:
-0 - 15 VFs = Up to 8 traffic classes, depending on device support
-16 - 31 VFs = Up to 4 traffic classes
-32 - 63 VFs = 1 traffic class
-
-When VFs are configured, the PF is allocated one pool as well. The PF supports
-the DCB features with the constraint that each traffic class will only use a
-single queue pair. When zero VFs are configured, the PF can support multiple
-queue pairs per traffic class.
-
-allow_unsupported_sfp
----------------------
-:Valid Range: 0,1
-:Default Value: 0 (disabled)
-
-This parameter allows unsupported and untested SFP+ modules on 82599-based
-adapters, as long as the type of module is known to the driver.
-
-debug
------
-:Valid Range: 0-16 (0=none,...,16=all)
-:Default Value: 0
-
-This parameter adjusts the level of debug messages displayed in the system
-logs.
-
-
-Additional Features and Configurations
-======================================
-
-Flow Control
-------------
-Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
-receiving and transmitting pause frames for ixgbe. When transmit is enabled,
-pause frames are generated when the receive packet buffer crosses a predefined
-threshold. When receive is enabled, the transmit unit will halt for the time
-delay specified when a pause frame is received.
-
-NOTE: You must have a flow control capable link partner.
-
-Flow Control is enabled by default.
-
-Use ethtool to change the flow control settings. To enable or disable Rx or
-Tx Flow Control::
-
-  ethtool -A eth? rx <on|off> tx <on|off>
-
-Note: This command only enables or disables Flow Control if auto-negotiation is
-disabled. If auto-negotiation is enabled, this command changes the parameters
-used for auto-negotiation with the link partner.
-
-To enable or disable auto-negotiation::
-
-  ethtool -s eth? autoneg <on|off>
-
-Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
-on your device, you may not be able to change the auto-negotiation setting.
-
-NOTE: For 82598 backplane cards entering 1 gigabit mode, flow control default
-behavior is changed to off. Flow control in 1 gigabit mode on these devices can
-lead to transmit hangs.
-
-Intel(R) Ethernet Flow Director
--------------------------------
-The Intel Ethernet Flow Director performs the following tasks:
-
-- Directs receive packets according to their flows to different queues.
-- Enables tight control on routing a flow in the platform.
-- Matches flows and CPU cores for flow affinity.
-- Supports multiple parameters for flexible flow classification and load
-  balancing (in SFP mode only).
-
-NOTE: Intel Ethernet Flow Director masking works in the opposite manner from
-subnet masking. In the following command::
-
-  #ethtool -N eth11 flow-type ip4 src-ip 172.4.1.2 m 255.0.0.0 dst-ip \
-  172.21.1.1 m 255.128.0.0 action 31
-
-The src-ip value that is written to the filter will be 0.4.1.2, not 172.0.0.0
-as might be expected. Similarly, the dst-ip value written to the filter will be
-0.21.1.1, not 172.0.0.0.
-
-To enable or disable the Intel Ethernet Flow Director::
-
-  # ethtool -K ethX ntuple <on|off>
-
-When disabling ntuple filters, all the user programmed filters are flushed from
-the driver cache and hardware. All needed filters must be re-added when ntuple
-is re-enabled.
-
-To add a filter that directs packet to queue 2, use -U or -N switch::
-
-  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
-  192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
-
-To see the list of filters currently present::
-
-  # ethtool <-u|-n> ethX
-
-Sideband Perfect Filters
-------------------------
-Sideband Perfect Filters are used to direct traffic that matches specified
-characteristics. They are enabled through ethtool's ntuple interface. To add a
-new filter use the following command::
-
-  ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
-  dst-port <port> action <queue>
-
-Where:
-  <device> - the ethernet device to program
-  <type> - can be ip4, tcp4, udp4, or sctp4
-  <ip> - the IP address to match on
-  <port> - the port number to match on
-  <queue> - the queue to direct traffic towards (-1 discards the matched traffic)
-
-Use the following command to delete a filter::
-
-  ethtool -U <device> delete <N>
-
-Where <N> is the filter id displayed when printing all the active filters, and
-may also have been specified using "loc <N>" when adding the filter.
-
-The following example matches TCP traffic sent from 192.168.0.1, port 5300,
-directed to 192.168.0.5, port 80, and sends it to queue 7::
-
-  ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
-  src-port 5300 dst-port 80 action 7
-
-For each flow-type, the programmed filters must all have the same matching
-input set. For example, issuing the following two commands is acceptable::
-
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
-
-Issuing the next two commands, however, is not acceptable, since the first
-specifies src-ip and the second specifies dst-ip::
-
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
-  ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
-
-The second command will fail with an error. You may program multiple filters
-with the same fields, using different values, but, on one device, you may not
-program two TCP4 filters with different matching fields.
-
-Matching on a sub-portion of a field is not supported by the ixgbe driver, thus
-partial mask fields are not supported.
-
-To create filters that direct traffic to a specific Virtual Function, use the
-"user-def" parameter. Specify the user-def as a 64 bit value, where the lower 32
-bits represents the queue number, while the next 8 bits represent which VF.
-Note that 0 is the PF, so the VF identifier is offset by 1. For example::
-
-  ... user-def 0x800000002 ...
-
-specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
-that VF.
-
-Note that these filters will not break internal routing rules, and will not
-route traffic that otherwise would not have been sent to the specified Virtual
-Function.
-
-Jumbo Frames
-------------
-Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
-to a value larger than the default value of 1500.
-
-Use the ifconfig command to increase the MTU size. For example, enter the
-following where <x> is the interface number::
-
-  ifconfig eth<x> mtu 9000 up
-
-Alternatively, you can use the ip command as follows::
-
-  ip link set mtu 9000 dev eth<x>
-  ip link set up dev eth<x>
-
-This setting is not saved across reboots. The setting change can be made
-permanent by adding 'MTU=9000' to the file::
-
-  /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
-  /etc/sysconfig/network/<config_file> // for SLES
-
-NOTE: The maximum MTU setting for Jumbo Frames is 9710. This value coincides
-with the maximum Jumbo Frames size of 9728 bytes.
-
-NOTE: This driver will attempt to use multiple page sized buffers to receive
-each jumbo packet. This should help to avoid buffer starvation issues when
-allocating receive packets.
-
-NOTE: For 82599-based network connections, if you are enabling jumbo frames in
-a virtual function (VF), jumbo frames must first be enabled in the physical
-function (PF). The VF MTU setting cannot be larger than the PF MTU.
-
-Generic Receive Offload, aka GRO
---------------------------------
-The driver supports the in-kernel software implementation of GRO. GRO has
-shown that by coalescing Rx traffic into larger chunks of data, CPU
-utilization can be significantly reduced when under large Rx load. GRO is an
-evolution of the previously-used LRO interface. GRO is able to coalesce
-other protocols besides TCP. It's also safe to use with configurations that
-are problematic for LRO, namely bridging and iSCSI.
-
-Data Center Bridging (DCB)
---------------------------
-NOTE:
-The kernel assumes that TC0 is available, and will disable Priority Flow
-Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
-enabled when setting up DCB on your switch.
-
-DCB is a configuration Quality of Service implementation in hardware. It uses
-the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
-different priorities that traffic can be filtered into. It also enables
-priority flow control (802.1Qbb) which can limit or eliminate the number of
-dropped packets during network stress. Bandwidth can be allocated to each of
-these priorities, which is enforced at the hardware level (802.1Qaz).
-
-Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
-802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
-and can accept settings from a DCBX capable peer. Software configuration of
-DCBX parameters via dcbtool/lldptool are not supported.
-
-The ixgbe driver implements the DCB netlink interface layer to allow user-space
-to communicate with the driver and query DCB configuration for the port.
-
-ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information. The latest ethtool
-version is required for this functionality. Download it at:
-https://www.kernel.org/pub/software/network/ethtool/
-
-FCoE
-----
-The ixgbe driver supports Fiber Channel over Ethernet (FCoE) and Data Center
-Bridging (DCB). This code has no default effect on the regular driver
-operation. Configuring DCB and FCoE is outside the scope of this README. Refer
-to http://www.open-fcoe.org/ for FCoE project information and contact
-ixgbe-eedc@lists.sourceforge.net for DCB information.
-
-MAC and VLAN anti-spoofing feature
-----------------------------------
-When a malicious driver attempts to send a spoofed packet, it is dropped by the
-hardware and not transmitted.
-
-An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
-spoofed packet is detected, the PF driver will send the following message to
-the system log (displayed by the "dmesg" command)::
-
-  ixgbe ethX: ixgbe_spoof_check: n spoofed packets detected
-
-where "x" is the PF interface number; and "n" is number of spoofed packets.
-NOTE: This feature can be disabled for a specific Virtual Function (VF)::
-
-  ip link set <pf dev> vf <vf id> spoofchk {off|on}
-
-IPsec Offload
--------------
-The ixgbe driver supports IPsec Hardware Offload.  When creating Security
-Associations with "ip xfrm ..." the 'offload' tag option can be used to
-register the IPsec SA with the driver in order to get higher throughput in
-the secure communications.
-
-The offload is also supported for ixgbe's VFs, but the VF must be set as
-'trusted' and the support must be enabled with::
-
-  ethtool --set-priv-flags eth<x> vf-ipsec on
-  ip link set eth<x> vf <y> trust on
-

-Overview
-========
-
-Resource virtualization unit (RVU) on Marvell's OcteonTX2 SOC maps HW
-resources from the network, crypto and other functional blocks into
-PCI-compatible physical and virtual functions. Each functional block
-again has multiple local functions (LFs) for provisioning to PCI devices.
-RVU supports multiple PCIe SRIOV physical functions (PFs) and virtual
-functions (VFs). PF0 is called the administrative / admin function (AF)
-and has privileges to provision RVU functional block's LFs to each of the
-PF/VF.
-
-RVU managed networking functional blocks
- - Network pool or buffer allocator (NPA)
- - Network interface controller (NIX)
- - Network parser CAM (NPC)
- - Schedule/Synchronize/Order unit (SSO)
- - Loopback interface (LBK)
-
-RVU managed non-networking functional blocks
- - Crypto accelerator (CPT)
- - Scheduled timers unit (TIM)
- - Schedule/Synchronize/Order unit (SSO)
-   Used for both networking and non networking usecases
-
-Resource provisioning examples
- - A PF/VF with NIX-LF & NPA-LF resources works as a pure network device
- - A PF/VF with CPT-LF resource works as a pure crypto offload device.
-
-RVU functional blocks are highly configurable as per software requirements.
-
-Firmware setups following stuff before kernel boots
- - Enables required number of RVU PFs based on number of physical links.
- - Number of VFs per PF are either static or configurable at compile time.
-   Based on config, firmware assigns VFs to each of the PFs.
- - Also assigns MSIX vectors to each of PF and VFs.
- - These are not changed after kernel boot.
-
-Drivers
-=======
-
-Linux kernel will have multiple drivers registering to different PF and VFs
-of RVU. Wrt networking there will be 3 flavours of drivers.
-
-Admin Function driver
----------------------
-
-As mentioned above RVU PF0 is called the admin function (AF), this driver
-supports resource provisioning and configuration of functional blocks.
-Doesn't handle any I/O. It sets up few basic stuff but most of the
-funcionality is achieved via configuration requests from PFs and VFs.
-
-PF/VFs communicates with AF via a shared memory region (mailbox). Upon
-receiving requests AF does resource provisioning and other HW configuration.
-AF is always attached to host kernel, but PFs and their VFs may be used by host
-kernel itself, or attached to VMs or to userspace applications like
-DPDK etc. So AF has to handle provisioning/configuration requests sent
-by any device from any domain.
-
-AF driver also interacts with underlying firmware to
- - Manage physical ethernet links ie CGX LMACs.
- - Retrieve information like speed, duplex, autoneg etc
- - Retrieve PHY EEPROM and stats.
- - Configure FEC, PAM modes
- - etc
-
-From pure networking side AF driver supports following functionality.
- - Map a physical link to a RVU PF to which a netdev is registered.
- - Attach NIX and NPA block LFs to RVU PF/VF which provide buffer pools, RQs, SQs
-   for regular networking functionality.
- - Flow control (pause frames) enable/disable/config.
- - HW PTP timestamping related config.
- - NPC parser profile config, basically how to parse pkt and what info to extract.
- - NPC extract profile config, what to extract from the pkt to match data in MCAM entries.
- - Manage NPC MCAM entries, upon request can frame and install requested packet forwarding rules.
- - Defines receive side scaling (RSS) algorithms.
- - Defines segmentation offload algorithms (eg TSO)
- - VLAN stripping, capture and insertion config.
- - SSO and TIM blocks config which provide packet scheduling support.
- - Debugfs support, to check current resource provising, current status of
-   NPA pools, NIX RQ, SQ and CQs, various stats etc which helps in debugging issues.
- - And many more.
-
-Physical Function driver
-------------------------
-
-This RVU PF handles IO, is mapped to a physical ethernet link and this
-driver registers a netdev. This supports SR-IOV. As said above this driver
-communicates with AF with a mailbox. To retrieve information from physical
-links this driver talks to AF and AF gets that info from firmware and responds
-back ie cannot talk to firmware directly.
-
-Supports ethtool for configuring links, RSS, queue count, queue size,
-flow control, ntuple filters, dump PHY EEPROM, config FEC etc.
-
-Virtual Function driver
------------------------
-
-There are two types VFs, VFs that share the physical link with their parent
-SR-IOV PF and the VFs which work in pairs using internal HW loopback channels (LBK).
-
-Type1:
- - These VFs and their parent PF share a physical link and used for outside communication.
- - VFs cannot communicate with AF directly, they send mbox message to PF and PF
-   forwards that to AF. AF after processing, responds back to PF and PF forwards
-   the reply to VF.
- - From functionality point of view there is no difference between PF and VF as same type
-   HW resources are attached to both. But user would be able to configure few stuff only
-   from PF as PF is treated as owner/admin of the link.
-
-Type2:
- - RVU PF0 ie admin function creates these VFs and maps them to loopback block's channels.
- - A set of two VFs (VF0 & VF1, VF2 & VF3 .. so on) works as a pair ie pkts sent out of
-   VF0 will be received by VF1 and viceversa.
- - These VFs can be used by applications or virtual machines to communicate between them
-   without sending traffic outside. There is no switch present in HW, hence the support
-   for loopback VFs.
- - These communicate directly with AF (PF0) via mbox.
-
-Except for the IO channels or links used for packet reception and transmission there is
-no other difference between these VF types. AF driver takes care of IO channel mapping,
-hence same VF driver works for both types of devices.
-
-Basic packet flow
-=================
-
-Ingress
--------
-
-1. CGX LMAC receives packet.
-2. Forwards the packet to the NIX block.
-3. Then submitted to NPC block for parsing and then MCAM lookup to get the destination RVU device.
-4. NIX LF attached to the destination RVU device allocates a buffer from RQ mapped buffer pool of NPA block LF.
-5. RQ may be selected by RSS or by configuring MCAM rule with a RQ number.
-6. Packet is DMA'ed and driver is notified.
-
-Egress
-------
-
-1. Driver prepares a send descriptor and submits to SQ for transmission.
-2. The SQ is already configured (by AF) to transmit on a specific link/channel.
-3. The SQ descriptor ring is maintained in buffers allocated from SQ mapped pool of NPA block LF.
-4. NIX block transmits the pkt on the designated channel.
-5. NPC MCAM entries can be installed to divert pkt onto a different channel.

-Enabling the driver and kconfig options
-================================================
-
-| mlx5 core is modular and most of the major mlx5 core driver features can be selected (compiled in/out)
-| at build time via kernel Kconfig flags.
-| Basic features, ethernet net device rx/tx offloads and XDP, are available with the most basic flags
-| CONFIG_MLX5_CORE=y/m and CONFIG_MLX5_CORE_EN=y.
-| For the list of advanced features please see below.

-
-Devlink info
-============
-
-The devlink info reports the running and stored firmware versions on device.
-It also prints the device PSID which represents the HCA board type ID.
-
-User command example::
-
-   $ devlink dev info pci/0000:00:06.0
-      pci/0000:00:06.0:
-      driver mlx5_core
-      versions:
-         fixed:
-            fw.psid MT_0000000009
-         running:
-            fw.version 16.26.0100
-         stored:
-            fw.version 16.26.0100
-
-Devlink parameters
-==================
-
-flow_steering_mode: Device flow steering mode
----------------------------------------------
-The flow steering mode parameter controls the flow steering mode of the driver.
-Two modes are supported:
-1. 'dmfs' - Device managed flow steering.
-2. 'smfs  - Software/Driver managed flow steering.
-
-In DMFS mode, the HW steering entities are created and managed through the
-Firmware.
-In SMFS mode, the HW steering entities are created and managed though by
-the driver directly into Hardware without firmware intervention.
-
-SMFS mode is faster and provides better rule inserstion rate compared to default DMFS mode.
-
-User command examples:
-
-- Set SMFS flow steering mode::
-
-    $ devlink dev param set pci/0000:06:00.0 name flow_steering_mode value "smfs" cmode runtime
-
-- Read device flow steering mode::
-
-    $ devlink dev param show pci/0000:06:00.0 name flow_steering_mode
-      pci/0000:06:00.0:
-      name flow_steering_mode type driver-specific
-      values:
-         cmode runtime value smfs
-
-enable_roce: RoCE enablement state
-----------------------------------
-RoCE enablement state controls driver support for RoCE traffic.
-When RoCE is disabled, there is no gid table, only raw ethernet QPs are supported and traffic on the well known UDP RoCE port is handled as raw ethernet traffic.
-
-To change RoCE enablement state a user must change the driverinit cmode value and run devlink reload.
-
-User command examples:
-
-- Disable RoCE::
-
-    $ devlink dev param set pci/0000:06:00.0 name enable_roce value false cmode driverinit
-    $ devlink dev reload pci/0000:06:00.0
-
-- Read RoCE enablement state::
-
-    $ devlink dev param show pci/0000:06:00.0 name enable_roce
-      pci/0000:06:00.0:
-      name enable_roce type generic
-      values:
-         cmode driverinit value true
-
-Devlink health reporters
-========================
-
-tx reporter
------------
-The tx reporter is responsible for reporting and recovering of the following two error scenarios:
-
-- TX timeout
-    Report on kernel tx timeout detection.
-    Recover by searching lost interrupts.
-- TX error completion
-    Report on error tx completion.
-    Recover by flushing the TX queue and reset it.
-
-TX reporter also support on demand diagnose callback, on which it provides
-real time information of its send queues status.
-
-User commands examples:
-
-- Diagnose send queues status::
-
-    $ devlink health diagnose pci/0000:82:00.0 reporter tx
-
-NOTE: This command has valid output only when interface is up, otherwise the command has empty output.
-
-- Show number of tx errors indicated, number of recover flows ended successfully,
-  is autorecover enabled and graceful period from last recover::
-
-    $ devlink health show pci/0000:82:00.0 reporter tx
-
-rx reporter
------------
-The rx reporter is responsible for reporting and recovering of the following two error scenarios:
-
-- RX queues initialization (population) timeout
-    RX queues descriptors population on ring initialization is done in
-    napi context via triggering an irq, in case of a failure to get
-    the minimum amount of descriptors, a timeout would occur and it
-    could be recoverable by polling the EQ (Event Queue).
-- RX completions with errors (reported by HW on interrupt context)
-    Report on rx completion error.
-    Recover (if needed) by flushing the related queue and reset it.
-
-RX reporter also supports on demand diagnose callback, on which it
-provides real time information of its receive queues status.
-
-- Diagnose rx queues status, and corresponding completion queue::
-
-    $ devlink health diagnose pci/0000:82:00.0 reporter rx
-
-NOTE: This command has valid output only when interface is up, otherwise the command has empty output.
-
-- Show number of rx errors indicated, number of recover flows ended successfully,
-  is autorecover enabled and graceful period from last recover::
-
-    $ devlink health show pci/0000:82:00.0 reporter rx
-
-fw reporter
------------
-The fw reporter implements diagnose and dump callbacks.
-It follows symptoms of fw error such as fw syndrome by triggering
-fw core dump and storing it into the dump buffer.
-The fw reporter diagnose command can be triggered any time by the user to check
-current fw status.
-
-User commands examples:
-
-- Check fw heath status::
-
-    $ devlink health diagnose pci/0000:82:00.0 reporter fw
-
-- Read FW core dump if already stored or trigger new one::
-
-    $ devlink health dump show pci/0000:82:00.0 reporter fw
-
-NOTE: This command can run only on the PF which has fw tracer ownership,
-running it on other PF or any VF will return "Operation not permitted".
-
-fw fatal reporter
------------------
-The fw fatal reporter implements dump and recover callbacks.
-It follows fatal errors indications by CR-space dump and recover flow.
-The CR-space dump uses vsc interface which is valid even if the FW command
-interface is not functional, which is the case in most FW fatal errors.
-The recover function runs recover flow which reloads the driver and triggers fw
-reset if needed.
-
-User commands examples:
-
-- Run fw recover flow manually::
-
-    $ devlink health recover pci/0000:82:00.0 reporter fw_fatal
-
-- Read FW CR-space dump if already strored or trigger new one::
-
-    $ devlink health dump show pci/0000:82:00.1 reporter fw_fatal
-
-NOTE: This command can run only on PF.
-
-mlx5 tracepoints
-================
-
-mlx5 driver provides internal trace points for tracking and debugging using
-kernel tracepoints interfaces (refer to Documentation/trace/ftrace.rst).
-
-For the list of support mlx5 events check /sys/kernel/debug/tracing/events/mlx5/
-
-tc and eswitch offloads tracepoints:
-

-======================
-Hyper-V network driver
-======================
-
-Compatibility
-=============
-
-This driver is compatible with Windows Server 2012 R2, 2016 and
-Windows 10.
-
-Features
-========
-
-Checksum offload
-----------------
-  The netvsc driver supports checksum offload as long as the
-  Hyper-V host version does. Windows Server 2016 and Azure
-  support checksum offload for TCP and UDP for both IPv4 and
-  IPv6. Windows Server 2012 only supports checksum offload for TCP.
-
-Receive Side Scaling
---------------------
-  Hyper-V supports receive side scaling. For TCP & UDP, packets can
-  be distributed among available queues based on IP address and port
-  number.
-
-  For TCP & UDP, we can switch hash level between L3 and L4 by ethtool
-  command. TCP/UDP over IPv4 and v6 can be set differently. The default
-  hash level is L4. We currently only allow switching TX hash level
-  from within the guests.
-
-  On Azure, fragmented UDP packets have high loss rate with L4
-  hashing. Using L3 hashing is recommended in this case.
-
-  For example, for UDP over IPv4 on eth0:
-
-  To include UDP port numbers in hashing::
-
-	ethtool -N eth0 rx-flow-hash udp4 sdfn
-
-  To exclude UDP port numbers in hashing::
-
-	ethtool -N eth0 rx-flow-hash udp4 sd
-
-  To show UDP hash level::
-
-	ethtool -n eth0 rx-flow-hash udp4
-
-Generic Receive Offload, aka GRO
---------------------------------
-  The driver supports GRO and it is enabled by default. GRO coalesces
-  like packets and significantly reduces CPU usage under heavy Rx
-  load.
-
-Large Receive Offload (LRO), or Receive Side Coalescing (RSC)
--------------------------------------------------------------
-  The driver supports LRO/RSC in the vSwitch feature. It reduces the per packet
-  processing overhead by coalescing multiple TCP segments when possible. The
-  feature is enabled by default on VMs running on Windows Server 2019 and
-  later. It may be changed by ethtool command::
-
-	ethtool -K eth0 lro on
-	ethtool -K eth0 lro off
-
-SR-IOV support
---------------
-  Hyper-V supports SR-IOV as a hardware acceleration option. If SR-IOV
-  is enabled in both the vSwitch and the guest configuration, then the
-  Virtual Function (VF) device is passed to the guest as a PCI
-  device. In this case, both a synthetic (netvsc) and VF device are
-  visible in the guest OS and both NIC's have the same MAC address.
-
-  The VF is enslaved by netvsc device.  The netvsc driver will transparently
-  switch the data path to the VF when it is available and up.
-  Network state (addresses, firewall, etc) should be applied only to the
-  netvsc device; the slave device should not be accessed directly in
-  most cases.  The exceptions are if some special queue discipline or
-  flow direction is desired, these should be applied directly to the
-  VF slave device.
-
-Receive Buffer
---------------
-  Packets are received into a receive area which is created when device
-  is probed. The receive area is broken into MTU sized chunks and each may
-  contain one or more packets. The number of receive sections may be changed
-  via ethtool Rx ring parameters.
-
-  There is a similar send buffer which is used to aggregate packets for sending.
-  The send area is broken into chunks of 6144 bytes, each of section may
-  contain one or more packets. The send buffer is an optimization, the driver
-  will use slower method to handle very large packets or if the send buffer
-  area is exhausted.
-
-XDP support
------------
-  XDP (eXpress Data Path) is a feature that runs eBPF bytecode at the early
-  stage when packets arrive at a NIC card. The goal is to increase performance
-  for packet processing, reducing the overhead of SKB allocation and other
-  upper network layers.
-
-  hv_netvsc supports XDP in native mode, and transparently sets the XDP
-  program on the associated VF NIC as well.
-
-  Setting / unsetting XDP program on synthetic NIC (netvsc) propagates to
-  VF NIC automatically. Setting / unsetting XDP program on VF NIC directly
-  is not recommended, also not propagated to synthetic NIC, and may be
-  overwritten by setting of synthetic NIC.
-
-  XDP program cannot run with LRO (RSC) enabled, so you need to disable LRO
-  before running XDP::
-
-	ethtool -K eth0 lro off
-
-  XDP_REDIRECT action is not yet supported.

-  - 3.  Features supported
-  - 4.  Command line parameters
-  - 5.  Performance suggestions
-  - 6.  Available Downloads
-
-
-1. Introduction
-===============
-This Linux driver supports Neterion's Xframe I PCI-X 1.0 and
-Xframe II PCI-X 2.0 adapters. It supports several features
-such as jumbo frames, MSI/MSI-X, checksum offloads, TSO, UFO and so on.
-See below for complete list of features.
-
-All features are supported for both IPv4 and IPv6.
-
-2. Identifying the adapter/interface
-====================================
-
-a. Insert the adapter(s) in your system.
-b. Build and load driver::
-
-	# insmod s2io.ko
-
-c. View log messages::
-
-	# dmesg | tail -40
-
-You will see messages similar to::
-
-	eth3: Neterion Xframe I 10GbE adapter (rev 3), Version 2.0.9.1, Intr type INTA
-	eth4: Neterion Xframe II 10GbE adapter (rev 2), Version 2.0.9.1, Intr type INTA
-	eth4: Device is on 64 bit 133MHz PCIX(M1) bus
-
-The above messages identify the adapter type(Xframe I/II), adapter revision,
-driver version, interface name(eth3, eth4), Interrupt type(INTA, MSI, MSI-X).
-In case of Xframe II, the PCI/PCI-X bus width and frequency are displayed
-as well.
-
-To associate an interface with a physical adapter use "ethtool -p <ethX>".
-The corresponding adapter's LED will blink multiple times.
-
-3. Features supported
-=====================
-a. Jumbo frames. Xframe I/II supports MTU up to 9600 bytes,
-   modifiable using ip command.
-
-b. Offloads. Supports checksum offload(TCP/UDP/IP) on transmit
-   and receive, TSO.
-
-c. Multi-buffer receive mode. Scattering of packet across multiple
-   buffers. Currently driver supports 2-buffer mode which yields
-   significant performance improvement on certain platforms(SGI Altix,
-   IBM xSeries).
-
-d. MSI/MSI-X. Can be enabled on platforms which support this feature
-   (IA64, Xeon) resulting in noticeable performance improvement(up to 7%
-   on certain platforms).
-
-e. Statistics. Comprehensive MAC-level and software statistics displayed
-   using "ethtool -S" option.
-
-f. Multi-FIFO/Ring. Supports up to 8 transmit queues and receive rings,
-   with multiple steering options.
-
-4. Command line parameters
-==========================
-
-a. tx_fifo_num
-	Number of transmit queues
-
-Valid range: 1-8
-
-Default: 1
-
-b. rx_ring_num
-	Number of receive rings
-
-Valid range: 1-8
-
-Default: 1
-
-c. tx_fifo_len
-	Size of each transmit queue
-
-Valid range: Total length of all queues should not exceed 8192
-
-Default: 4096
-
-d. rx_ring_sz
-	Size of each receive ring(in 4K blocks)
-
-Valid range: Limited by memory on system
-
-Default: 30
-
-e. intr_type
-	Specifies interrupt type. Possible values 0(INTA), 2(MSI-X)
-
-Valid values: 0, 2
-
-Default: 2
-
-5. Performance suggestions
-==========================
-
-General:
-
-a. Set MTU to maximum(9000 for switch setup, 9600 in back-to-back configuration)
-b. Set TCP windows size to optimal value.
-
-For instance, for MTU=1500 a value of 210K has been observed to result in
-good performance::
-
-	# sysctl -w net.ipv4.tcp_rmem="210000 210000 210000"
-	# sysctl -w net.ipv4.tcp_wmem="210000 210000 210000"
-
-For MTU=9000, TCP window size of 10 MB is recommended::
-
-	# sysctl -w net.ipv4.tcp_rmem="10000000 10000000 10000000"
-	# sysctl -w net.ipv4.tcp_wmem="10000000 10000000 10000000"
-
-Transmit performance:
-
-a. By default, the driver respects BIOS settings for PCI bus parameters.
-   However, you may want to experiment with PCI bus parameters
-   max-split-transactions(MOST) and MMRBC (use setpci command).
-
-   A MOST value of 2 has been found optimal for Opterons and 3 for Itanium.
-
-   It could be different for your hardware.
-
-   Set MMRBC to 4K**.
-
-   For example you can set
-
-   For opteron::
-
-	#setpci -d 17d5:* 62=1d
-
-   For Itanium::
-
-	#setpci -d 17d5:* 62=3d
-
-   For detailed description of the PCI registers, please see Xframe User Guide.
-
-b. Ensure Transmit Checksum offload is enabled. Use ethtool to set/verify this
-   parameter.
-
-c. Turn on TSO(using "ethtool -K")::
-
-	# ethtool -K <ethX> tso on
-
-Receive performance:
-
-a. By default, the driver respects BIOS settings for PCI bus parameters.
-   However, you may want to set PCI latency timer to 248::
-
-	#setpci -d 17d5:* LATENCY_TIMER=f8
-
-   For detailed description of the PCI registers, please see Xframe User Guide.
-
-b. Use 2-buffer mode. This results in large performance boost on
-   certain platforms(eg. SGI Altix, IBM xSeries).
-
-c. Ensure Receive Checksum offload is enabled. Use "ethtool -K ethX" command to
-   set/verify this option.
-
-d. Enable NAPI feature(in kernel configuration Device Drivers ---> Network
-   device support --->  Ethernet (10000 Mbit) ---> S2IO 10Gbe Xframe NIC) to
-   bring down CPU utilization.
-
-.. note::
-
-   For AMD opteron platforms with 8131 chipset, MMRBC=1 and MOST=1 are
-   recommended as safe parameters.

-
-Overview
-========
-
-This driver supports Netronome's line of Flow Processor devices,
-including the NFP4000, NFP5000, and NFP6000 models, which are also
-incorporated in the company's family of Agilio SmartNICs. The SR-IOV
-physical and virtual functions for these devices are supported by
-the driver.
-
-Acquiring Firmware
-==================
-
-The NFP4000 and NFP6000 devices require application specific firmware
-to function.  Application firmware can be located either on the host file system
-or in the device flash (if supported by management firmware).
-
-Firmware files on the host filesystem contain card type (`AMDA-*` string), media
-config etc.  They should be placed in `/lib/firmware/netronome` directory to
-load firmware from the host file system.
-
-Firmware for basic NIC operation is available in the upstream
-`linux-firmware.git` repository.
-
-Firmware in NVRAM
------------------
-
-Recent versions of management firmware supports loading application
-firmware from flash when the host driver gets probed.  The firmware loading
-policy configuration may be used to configure this feature appropriately.
-
-Devlink or ethtool can be used to update the application firmware on the device
-flash by providing the appropriate `nic_AMDA*.nffw` file to the respective
-command.  Users need to take care to write the correct firmware image for the
-card and media configuration to flash.
-
-Available storage space in flash depends on the card being used.
-
-Dealing with multiple projects
-------------------------------
-
-NFP hardware is fully programmable therefore there can be different
-firmware images targeting different applications.
-
-When using application firmware from host, we recommend placing
-actual firmware files in application-named subdirectories in
-`/lib/firmware/netronome` and linking the desired files, e.g.::
-
-    $ tree /lib/firmware/netronome/
-    /lib/firmware/netronome/
-    ├── bpf
-    │   ├── nic_AMDA0081-0001_1x40.nffw
-    │   └── nic_AMDA0081-0001_4x10.nffw
-    ├── flower
-    │   ├── nic_AMDA0081-0001_1x40.nffw
-    │   └── nic_AMDA0081-0001_4x10.nffw
-    ├── nic
-    │   ├── nic_AMDA0081-0001_1x40.nffw
-    │   └── nic_AMDA0081-0001_4x10.nffw
-    ├── nic_AMDA0081-0001_1x40.nffw -> bpf/nic_AMDA0081-0001_1x40.nffw
-    └── nic_AMDA0081-0001_4x10.nffw -> bpf/nic_AMDA0081-0001_4x10.nffw
-
-    3 directories, 8 files
-
-You may need to use hard instead of symbolic links on distributions
-which use old `mkinitrd` command instead of `dracut` (e.g. Ubuntu).
-
-After changing firmware files you may need to regenerate the initramfs
-image.  Initramfs contains drivers and firmware files your system may
-need to boot.  Refer to the documentation of your distribution to find
-out how to update initramfs.  Good indication of stale initramfs
-is system loading wrong driver or firmware on boot, but when driver is
-later reloaded manually everything works correctly.
-
-Selecting firmware per device
------------------------------
-
-Most commonly all cards on the system use the same type of firmware.
-If you want to load specific firmware image for a specific card, you
-can use either the PCI bus address or serial number.  Driver will print
-which files it's looking for when it recognizes a NFP device::
-
-    nfp: Looking for firmware file in order of priority:
-    nfp:  netronome/serial-00-12-34-aa-bb-cc-10-ff.nffw: not found
-    nfp:  netronome/pci-0000:02:00.0.nffw: not found
-    nfp:  netronome/nic_AMDA0081-0001_1x40.nffw: found, loading...
-
-In this case if file (or link) called *serial-00-12-34-aa-bb-5d-10-ff.nffw*
-or *pci-0000:02:00.0.nffw* is present in `/lib/firmware/netronome` this
-firmware file will take precedence over `nic_AMDA*` files.
-
-Note that `serial-*` and `pci-*` files are **not** automatically included
-in initramfs, you will have to refer to documentation of appropriate tools
-to find out how to include them.
-
-Firmware loading policy
------------------------
-
-Firmware loading policy is controlled via three HWinfo parameters
-stored as key value pairs in the device flash:
-
-app_fw_from_flash
-    Defines which firmware should take precedence, 'Disk' (0), 'Flash' (1) or
-    the 'Preferred' (2) firmware. When 'Preferred' is selected, the management
-    firmware makes the decision over which firmware will be loaded by comparing
-    versions of the flash firmware and the host supplied firmware.
-    This variable is configurable using the 'fw_load_policy'
-    devlink parameter.
-
-abi_drv_reset
-    Defines if the driver should reset the firmware when
-    the driver is probed, either 'Disk' (0) if firmware was found on disk,
-    'Always' (1) reset or 'Never' (2) reset. Note that the device is always
-    reset on driver unload if firmware was loaded when the driver was probed.
-    This variable is configurable using the 'reset_dev_on_drv_probe'
-    devlink parameter.
-
-abi_drv_load_ifc
-    Defines a list of PF devices allowed to load FW on the device.
-    This variable is not currently user configurable.
-
-Statistics
-==========
-
-Following device statistics are available through the ``ethtool -S`` interface:
-
-.. flat-table:: NFP device statistics
-   :header-rows: 1
-   :widths: 3 1 11
-
-   * - Name
-     - ID
-     - Meaning
-
-   * - dev_rx_discards
-     - 1
-     - Packet can be discarded on the RX path for one of the following reasons:
-
-        * The NIC is not in promisc mode, and the destination MAC address
-          doesn't match the interfaces' MAC address.
-        * The received packet is larger than the max buffer size on the host.
-          I.e. it exceeds the Layer 3 MRU.
-        * There is no freelist descriptor available on the host for the packet.
-          It is likely that the NIC couldn't cache one in time.
-        * A BPF program discarded the packet.
-        * The datapath drop action was executed.
-        * The MAC discarded the packet due to lack of ingress buffer space
-          on the NIC.
-
-   * - dev_rx_errors
-     - 2
-     - A packet can be counted (and dropped) as RX error for the following
-       reasons:
-
-       * A problem with the VEB lookup (only when SR-IOV is used).
-       * A physical layer problem that causes Ethernet errors, like FCS or
-         alignment errors. The cause is usually faulty cables or SFPs.
-
-   * - dev_rx_bytes
-     - 3
-     - Total number of bytes received.
-
-   * - dev_rx_uc_bytes
-     - 4
-     - Unicast bytes received.
-
-   * - dev_rx_mc_bytes
-     - 5
-     - Multicast bytes received.
-
-   * - dev_rx_bc_bytes

-   * - dev_rx_bc_pkts
-     - 9
-     - Broadcast packets received.
-
-   * - dev_tx_discards
-     - 10
-     - A packet can be discarded in the TX direction if the MAC is
-       being flow controlled and the NIC runs out of TX queue space.
-
-   * - dev_tx_errors
-     - 11
-     - A packet can be counted as TX error (and dropped) for one for the
-       following reasons:
-
-       * The packet is an LSO segment, but the Layer 3 or Layer 4 offset
-         could not be determined. Therefore LSO could not continue.
-       * An invalid packet descriptor was received over PCIe.
-       * The packet Layer 3 length exceeds the device MTU.
-       * An error on the MAC/physical layer. Usually due to faulty cables or
-         SFPs.
-       * A CTM buffer could not be allocated.
-       * The packet offset was incorrect and could not be fixed by the NIC.
-
-   * - dev_tx_bytes
-     - 12
-     - Total number of bytes transmitted.
-
-   * - dev_tx_uc_bytes

-Identifying the Adapter
-=======================
-
-To find if one or more Pensando PCI Ethernet devices are installed on the
-host, check for the PCI devices::
-
-  $ lspci -d 1dd8:
-  b5:00.0 Ethernet controller: Device 1dd8:1002
-  b6:00.0 Ethernet controller: Device 1dd8:1002
-
-If such devices are listed as above, then the ionic.ko driver should find
-and configure them for use.  There should be log entries in the kernel
-messages such as these::
-
-  $ dmesg | grep ionic
-  ionic 0000:b5:00.0: 126.016 Gb/s available PCIe bandwidth (8.0 GT/s PCIe x16 link)
-  ionic 0000:b5:00.0 enp181s0: renamed from eth0
-  ionic 0000:b5:00.0 enp181s0: Link up - 100 Gbps
-  ionic 0000:b6:00.0: 126.016 Gb/s available PCIe bandwidth (8.0 GT/s PCIe x16 link)
-  ionic 0000:b6:00.0 enp182s0: renamed from eth0
-  ionic 0000:b6:00.0 enp182s0: Link up - 100 Gbps
-
-Driver and firmware version information can be gathered with either of
-ethtool or devlink tools::
-
-  $ ethtool -i enp181s0
-  driver: ionic
-  version: 5.7.0
-  firmware-version: 1.8.0-28
-  ...
-
-  $ devlink dev info pci/0000:b5:00.0
-  pci/0000:b5:00.0:
-    driver ionic
-    serial_number FLM18420073
-    versions:
-        fixed:
-          asic.id 0x0
-          asic.rev 0x0
-        running:
-          fw 1.8.0-28
-
-See Documentation/networking/devlink/ionic.rst for more information
-on the devlink dev info data.
-
-Enabling the driver
-===================
-
-The driver is enabled via the standard kernel configuration system,
-using the make command::
-
-  make oldconfig/menuconfig/etc.
-
-The driver is located in the menu structure at:
-
-  -> Device Drivers
-    -> Network device support (NETDEVICES [=y])
-      -> Ethernet driver support
-        -> Pensando devices
-          -> Pensando Ethernet IONIC Support
-
-Configuring the Driver
-======================
-
-MTU
----
-
-Jumbo frame support is available with a maximim size of 9194 bytes.
-
-Interrupt coalescing
---------------------
-
-Interrupt coalescing can be configured by changing the rx-usecs value with
-the "ethtool -C" command.  The rx-usecs range is 0-190.  The tx-usecs value
-reflects the rx-usecs value as they are tied together on the same interrupt.
-
-SR-IOV
-------
-
-Minimal SR-IOV support is currently offered and can be enabled by setting
-the sysfs 'sriov_numvfs' value, if supported by your particular firmware
-configuration.
-
-Statistics
-==========
-
-Basic hardware stats
---------------------
-
-The commands ``netstat -i``, ``ip -s link show``, and ``ifconfig`` show
-a limited set of statistics taken directly from firmware.  For example::
-
-  $ ip -s link show enp181s0
-  7: enp181s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
-      link/ether 00:ae:cd:00:07:68 brd ff:ff:ff:ff:ff:ff
-      RX: bytes  packets  errors  dropped overrun mcast
-      414        5        0       0       0       0
-      TX: bytes  packets  errors  dropped carrier collsns
-      1384       18       0       0       0       0
-
-ethtool -S
-----------
-
-The statistics shown from the ``ethtool -S`` command includes a combination of
-driver counters and firmware counters, including port and queue specific values.
-The driver values are counters computed by the driver, and the firmware values
-are gathered by the firmware from the port hardware and passed through the
-driver with no further interpretation.

-Rmnet Driver
-============
-
-1. Introduction
-===============
-
-rmnet driver is used for supporting the Multiplexing and aggregation
-Protocol (MAP). This protocol is used by all recent chipsets using Qualcomm
-Technologies, Inc. modems.
-
-This driver can be used to register onto any physical network device in
-IP mode. Physical transports include USB, HSIC, PCIe and IP accelerator.
-
-Multiplexing allows for creation of logical netdevices (rmnet devices) to
-handle multiple private data networks (PDN) like a default internet, tethering,
-multimedia messaging service (MMS) or IP media subsystem (IMS). Hardware sends
-packets with MAP headers to rmnet. Based on the multiplexer id, rmnet
-routes to the appropriate PDN after removing the MAP header.
-
-Aggregation is required to achieve high data rates. This involves hardware
-sending aggregated bunch of MAP frames. rmnet driver will de-aggregate
-these MAP frames and send them to appropriate PDN's.
-
-2. Packet format
-================
-
-a. MAP packet (data / control)
-
-MAP header has the same endianness of the IP packet.
-
-Packet format::
-
-  Bit             0             1           2-7      8 - 15           16 - 31
-  Function   Command / Data   Reserved     Pad   Multiplexer ID    Payload length
-  Bit            32 - x
-  Function     Raw  Bytes
-
-Command (1)/ Data (0) bit value is to indicate if the packet is a MAP command
-or data packet. Control packet is used for transport level flow control. Data
-packets are standard IP packets.
-
-Reserved bits are usually zeroed out and to be ignored by receiver.
-
-Padding is number of bytes to be added for 4 byte alignment if required by
-hardware.
-
-Multiplexer ID is to indicate the PDN on which data has to be sent.
-
-Payload length includes the padding length but does not include MAP header
-length.
-
-b. MAP packet (command specific)::
-
-    Bit             0             1           2-7      8 - 15           16 - 31
-    Function   Command         Reserved     Pad   Multiplexer ID    Payload length
-    Bit          32 - 39        40 - 45    46 - 47       48 - 63
-    Function   Command name    Reserved   Command Type   Reserved
-    Bit          64 - 95
-    Function   Transaction ID
-    Bit          96 - 127
-    Function   Command data
-
-Command 1 indicates disabling flow while 2 is enabling flow
-
-Command types
-
-= ==========================================
-0 for MAP command request
-1 is to acknowledge the receipt of a command
-2 is for unsupported commands
-3 is for error during processing of commands
-= ==========================================
-
-c. Aggregation
-
-Aggregation is multiple MAP packets (can be data or command) delivered to
-rmnet in a single linear skb. rmnet will process the individual
-packets and either ACK the MAP command or deliver the IP packet to the
-network stack as needed
-
-MAP header|IP Packet|Optional padding|MAP header|IP Packet|Optional padding....
-
-MAP header|IP Packet|Optional padding|MAP header|Command Packet|Optional pad...
-
-3. Userspace configuration
-==========================
-
-rmnet userspace configuration is done through netlink library librmnetctl
-and command line utility rmnetcli. Utility is hosted in codeaurora forum git.
-The driver uses rtnl_link_ops for communication.

-SB100 device driver
-===================
-
-sb1000 is a module network device driver for the General Instrument (also known
-as NextLevel) SURFboard1000 internal cable modem board.  This is an ISA card
-which is used by a number of cable TV companies to provide cable modem access.
-It's a one-way downstream-only cable modem, meaning that your upstream net link
-is provided by your regular phone modem.
-
-This driver was written by Franco Venturi <fventuri@mediaone.net>.  He deserves
-a great deal of thanks for this wonderful piece of code!
-
-Needed tools
-============
-
-Support for this device is now a part of the standard Linux kernel.  The
-driver source code file is drivers/net/sb1000.c.  In addition to this
-you will need:
-
-1. The "cmconfig" program.  This is a utility which supplements "ifconfig"
-   to configure the cable modem and network interface (usually called "cm0");
-
-2. Several PPP scripts which live in /etc/ppp to make connecting via your
-   cable modem easy.
-
-   These utilities can be obtained from:
-
-      http://www.jacksonville.net/~fventuri/
-
-   in Franco's original source code distribution .tar.gz file.  Support for
-   the sb1000 driver can be found at:
-
-      - http://web.archive.org/web/%2E/http://home.adelphia.net/~siglercm/sb1000.html
-      - http://web.archive.org/web/%2E/http://linuxpower.cx/~cable/
-
-   along with these utilities.
-
-3. The standard isapnp tools.  These are necessary to configure your SB1000
-   card at boot time (or afterwards by hand) since it's a PnP card.
-
-   If you don't have these installed as a standard part of your Linux
-   distribution, you can find them at:
-
-      http://www.roestock.demon.co.uk/isapnptools/
-
-   or check your Linux distribution binary CD or their web site.  For help with
-   isapnp, pnpdump, or /etc/isapnp.conf, go to:
-
-      http://www.roestock.demon.co.uk/isapnptools/isapnpfaq.html
-
-Using the driver
-================
-
-To make the SB1000 card work, follow these steps:
-
-1. Run ``make config``, or ``make menuconfig``, or ``make xconfig``, whichever
-   you prefer, in the top kernel tree directory to set up your kernel
-   configuration.  Make sure to say "Y" to "Prompt for development drivers"
-   and to say "M" to the sb1000 driver.  Also say "Y" or "M" to all the standard
-   networking questions to get TCP/IP and PPP networking support.
-
-2. **BEFORE** you build the kernel, edit drivers/net/sb1000.c.  Make sure
-   to redefine the value of READ_DATA_PORT to match the I/O address used
-   by isapnp to access your PnP cards.  This is the value of READPORT in
-   /etc/isapnp.conf or given by the output of pnpdump.
-
-3. Build and install the kernel and modules as usual.
-
-4. Boot your new kernel following the usual procedures.
-
-5. Set up to configure the new SB1000 PnP card by capturing the output
-   of "pnpdump" to a file and editing this file to set the correct I/O ports,
-   IRQ, and DMA settings for all your PnP cards.  Make sure none of the settings
-   conflict with one another.  Then test this configuration by running the
-   "isapnp" command with your new config file as the input.  Check for
-   errors and fix as necessary.  (As an aside, I use I/O ports 0x110 and
-   0x310 and IRQ 11 for my SB1000 card and these work well for me.  YMMV.)
-   Then save the finished config file as /etc/isapnp.conf for proper
-   configuration on subsequent reboots.
-
-6. Download the original file sb1000-1.1.2.tar.gz from Franco's site or one of
-   the others referenced above.  As root, unpack it into a temporary directory
-   and do a ``make cmconfig`` and then ``install -c cmconfig /usr/local/sbin``.
-   Don't do ``make install`` because it expects to find all the utilities built
-   and ready for installation, not just cmconfig.
-
-7. As root, copy all the files under the ppp/ subdirectory in Franco's
-   tar file into /etc/ppp, being careful not to overwrite any files that are
-   already in there.  Then modify ppp@gi-on to set the correct login name,
-   phone number, and frequency for the cable modem.  Also edit pap-secrets
-   to specify your login name and password and any site-specific information
-   you need.
-
-8. Be sure to modify /etc/ppp/firewall to use ipchains instead of
-   the older ipfwadm commands from the 2.0.x kernels.  There's a neat utility to
-   convert ipfwadm commands to ipchains commands:
-
-	http://users.dhp.com/~whisper/ipfwadm2ipchains/
-
-   You may also wish to modify the firewall script to implement a different
-   firewalling scheme.
-
-9. Start the PPP connection via the script /etc/ppp/ppp@gi-on.  You must be
-   root to do this.  It's better to use a utility like sudo to execute
-   frequently used commands like this with root permissions if possible.  If you
-   connect successfully the cable modem interface will come up and you'll see a
-   driver message like this at the console::
-
-	 cm0: sb1000 at (0x110,0x310), csn 1, S/N 0x2a0d16d8, IRQ 11.
-	 sb1000.c:v1.1.2 6/01/98 (fventuri@mediaone.net)
-
-   The "ifconfig" command should show two new interfaces, ppp0 and cm0.
-
-   The command "cmconfig cm0" will give you information about the cable modem
-   interface.
-
-10. Try pinging a site via ``ping -c 5 www.yahoo.com``, for example.  You should
-    see packets received.
-
-11. If you can't get site names (like www.yahoo.com) to resolve into
-    IP addresses (like 204.71.200.67), be sure your /etc/resolv.conf file
-    has no syntax errors and has the right nameserver IP addresses in it.
-    If this doesn't help, try something like ``ping -c 5 204.71.200.67`` to
-    see if the networking is running but the DNS resolution is where the
-    problem lies.
-
-12. If you still have problems, go to the support web sites mentioned above
-    and read the information and documentation there.
-
-Common problems
-===============
-
-1. Packets go out on the ppp0 interface but don't come back on the cm0
-   interface.  It looks like I'm connected but I can't even ping any
-   numerical IP addresses.  (This happens predominantly on Debian systems due
-   to a default boot-time configuration script.)
-
-Solution
-   As root ``echo 0 > /proc/sys/net/ipv4/conf/cm0/rp_filter`` so it
-   can share the same IP address as the ppp0 interface.  Note that this
-   command should probably be added to the /etc/ppp/cablemodem script
-   *right*between* the "/sbin/ifconfig" and "/sbin/cmconfig" commands.
-   You may need to do this to /proc/sys/net/ipv4/conf/ppp0/rp_filter as well.
-   If you do this to /proc/sys/net/ipv4/conf/default/rp_filter on each reboot
-   (in rc.local or some such) then any interfaces can share the same IP
-   addresses.
-
-2. I get "unresolved symbol" error messages on executing ``insmod sb1000.o``.
-
-Solution
-   You probably have a non-matching kernel source tree and
-   /usr/include/linux and /usr/include/asm header files.  Make sure you
-   install the correct versions of the header files in these two directories.
-   Then rebuild and reinstall the kernel.
-
-3. When isapnp runs it reports an error, and my SB1000 card isn't working.
-
-Solution
-   There's a problem with later versions of isapnp using the "(CHECK)"
-   option in the lines that allocate the two I/O addresses for the SB1000 card.
-   This first popped up on RH 6.0.  Delete "(CHECK)" for the SB1000 I/O addresses.
-   Make sure they don't conflict with any other pieces of hardware first!  Then
-   rerun isapnp and go from there.
-
-4. I can't execute the /etc/ppp/ppp@gi-on file.
-
-Solution
-   As root do ``chmod ug+x /etc/ppp/ppp@gi-on``.
-
-5. The firewall script isn't working (with 2.2.x and higher kernels).
-
-Solution
-   Use the ipfwadm2ipchains script referenced above to convert the
-   /etc/ppp/firewall script from the deprecated ipfwadm commands to ipchains.
-
-6. I'm getting *tons* of firewall deny messages in the /var/kern.log,
-   /var/messages, and/or /var/syslog files, and they're filling up my /var
-   partition!!!
-
-Solution
-   First, tell your ISP that you're receiving DoS (Denial of Service)
-   and/or portscanning (UDP connection attempts) attacks!  Look over the deny
-   messages to figure out what the attack is and where it's coming from.  Next,
-   edit /etc/ppp/cablemodem and make sure the ",nobroadcast" option is turned on
-   to the "cmconfig" command (uncomment that line).  If you're not receiving these
-   denied packets on your broadcast interface (IP address xxx.yyy.zzz.255
-   typically), then someone is attacking your machine in particular.  Be careful
-   out there....
-
-7. Everything seems to work fine but my computer locks up after a while
-   (and typically during a lengthy download through the cable modem)!
-
-Solution
-   You may need to add a short delay in the driver to 'slow down' the
-   SURFboard because your PC might not be able to keep up with the transfer rate
-   of the SB1000. To do this, it's probably best to download Franco's
-   sb1000-1.1.2.tar.gz archive and build and install sb1000.o manually.  You'll
-   want to edit the 'Makefile' and look for the 'SB1000_DELAY'
-   define.  Uncomment those 'CFLAGS' lines (and comment out the default ones)
-   and try setting the delay to something like 60 microseconds with:
-   '-DSB1000_DELAY=60'.  Then do ``make`` and as root ``make install`` and try
-   it out.  If it still doesn't work or you like playing with the driver, you may
-   try other numbers.  Remember though that the higher the delay, the slower the
-   driver (which slows down the rest of the PC too when it is actively
-   used). Thanks to Ed Daiga for this tip!

-
-Driver Information and Notes
-============================
-
-Transmit Process
-----------------
-
-The xmit method is invoked when the kernel needs to transmit a packet; it sets
-the descriptors in the ring and informs the DMA engine that there is a packet
-ready to be transmitted.
-
-By default, the driver sets the ``NETIF_F_SG`` bit in the features field of
-the ``net_device`` structure, enabling the scatter-gather feature. This is
-true on chips and configurations where the checksum can be done in hardware.
-
-Once the controller has finished transmitting the packet, timer will be
-scheduled to release the transmit resources.
-
-Receive Process
----------------
-
-When one or more packets are received, an interrupt happens. The interrupts
-are not queued, so the driver has to scan all the descriptors in the ring
-during the receive process.
-
-This is based on NAPI, so the interrupt handler signals only if there is work
-to be done, and it exits. Then the poll method will be scheduled at some
-future point.
-
-The incoming packets are stored, by the DMA, in a list of pre-allocated socket
-buffers in order to avoid the memcpy (zero-copy).
-
-Interrupt Mitigation
---------------------
-
-The driver is able to mitigate the number of its DMA interrupts using NAPI for
-the reception on chips older than the 3.50. New chips have an HW RX Watchdog
-used for this mitigation.
-
-Mitigation parameters can be tuned by ethtool.
-
-WoL
----
-
-Wake up on Lan feature through Magic and Unicast frames are supported for the
-GMAC, GMAC4/5 and XGMAC core.
-
-DMA Descriptors
----------------
-
-Driver handles both normal and alternate descriptors. The latter has been only
-tested on DesignWare(R) Cores Ethernet MAC Universal version 3.41a and later.
-
-stmmac supports DMA descriptor to operate both in dual buffer (RING) and
-linked-list(CHAINED) mode. In RING each descriptor points to two data buffer
-pointers whereas in CHAINED mode they point to only one data buffer pointer.
-RING mode is the default.
-
-In CHAINED mode each descriptor will have pointer to next descriptor in the
-list, hence creating the explicit chaining in the descriptor itself, whereas
-such explicit chaining is not possible in RING mode.
-
-Extended Descriptors
---------------------
-
-The extended descriptors give us information about the Ethernet payload when
-it is carrying PTP packets or TCP/UDP/ICMP over IP. These are not available on
-GMAC Synopsys(R) chips older than the 3.50. At probe time the driver will
-decide if these can be actually used. This support also is mandatory for PTPv2
-because the extra descriptors are used for saving the hardware timestamps and
-Extended Status.
-
-Ethtool Support
----------------
-
-Ethtool is supported. For example, driver statistics (including RMON),
-internal errors can be taken using::
-
-    ethtool -S ethX
-
-Ethtool selftests are also supported. This allows to do some early sanity
-checks to the HW using MAC and PHY loopback mechanisms::
-
-    ethtool -t ethX
-
-Jumbo and Segmentation Offloading
----------------------------------
-
-Jumbo frames are supported and tested for the GMAC. The GSO has been also
-added but it's performed in software. LRO is not supported.
-
-TSO Support
------------
-
-TSO (TCP Segmentation Offload) feature is supported by GMAC > 4.x and XGMAC
-chip family. When a packet is sent through TCP protocol, the TCP stack ensures
-that the SKB provided to the low level driver (stmmac in our case) matches
-with the maximum frame len (IP header + TCP header + payload <= 1500 bytes
-(for MTU set to 1500)). It means that if an application using TCP want to send
-a packet which will have a length (after adding headers) > 1514 the packet
-will be split in several TCP packets: The data payload is split and headers
-(TCP/IP ..) are added. It is done by software.
-
-When TSO is enabled, the TCP stack doesn't care about the maximum frame length
-and provide SKB packet to stmmac as it is. The GMAC IP will have to perform
-the segmentation by it self to match with maximum frame length.
-
-This feature can be enabled in device tree through ``snps,tso`` entry.
-
-Energy Efficient Ethernet
--------------------------
-
-Energy Efficient Ethernet (EEE) enables IEEE 802.3 MAC sublayer along with a
-family of Physical layer to operate in the Low Power Idle (LPI) mode. The EEE
-mode supports the IEEE 802.3 MAC operation at 100Mbps, 1000Mbps and 1Gbps.
-
-The LPI mode allows power saving by switching off parts of the communication
-device functionality when there is no data to be transmitted & received.
-The system on both the side of the link can disable some functionalities and
-save power during the period of low-link utilization. The MAC controls whether
-the system should enter or exit the LPI mode and communicate this to PHY.
-
-As soon as the interface is opened, the driver verifies if the EEE can be
-supported. This is done by looking at both the DMA HW capability register and
-the PHY devices MCD registers.
-
-To enter in TX LPI mode the driver needs to have a software timer that enable
-and disable the LPI mode when there is nothing to be transmitted.
-
-Precision Time Protocol (PTP)
------------------------------
-
-The driver supports the IEEE 1588-2002, Precision Time Protocol (PTP), which
-enables precise synchronization of clocks in measurement and control systems
-implemented with technologies such as network communication.
-
-In addition to the basic timestamp features mentioned in IEEE 1588-2002
-Timestamps, new GMAC cores support the advanced timestamp features.
-IEEE 1588-2008 can be enabled when configuring the Kernel.
-
-SGMII/RGMII Support
--------------------
-
-New GMAC devices provide own way to manage RGMII/SGMII. This information is
-available at run-time by looking at the HW capability register. This means
-that the stmmac can manage auto-negotiation and link status w/o using the
-PHYLIB stuff. In fact, the HW provides a subset of extended registers to
-restart the ANE, verify Full/Half duplex mode and Speed. Thanks to these
-registers, it is possible to look at the Auto-negotiated Link Parter Ability.
-
-Physical
---------
-
-The driver is compatible with Physical Abstraction Layer to be connected with
-PHY and GPHY devices.
-
-Platform Information
---------------------
-
-Several information can be passed through the platform and device-tree.
-
-::
-
-    struct plat_stmmacenet_data {
-
-1) Bus identifier::
-
-        int bus_id;
-
-2) PHY Physical Address. If set to -1 the driver will pick the first PHY it
-finds::
-
-        int phy_addr;
-
-3) PHY Device Interface::
-
-        int interface;
-
-4) Specific platform fields for the MDIO bus::
-
-        struct stmmac_mdio_bus_data *mdio_bus_data;
-
-5) Internal DMA parameters::
-
-        struct stmmac_dma_cfg *dma_cfg;
-
-6) Fixed CSR Clock Range selection::
-
-        int clk_csr;
-
-7) HW uses the GMAC core::
-
-        int has_gmac;
-
-8) If set the MAC will use Enhanced Descriptors::
-
-        int enh_desc;
-
-9) Core is able to perform TX Checksum and/or RX Checksum in HW::
-
-        int tx_coe;
-        int rx_coe;
-
-11) Some HWs are not able to perform the csum in HW for over-sized frames due
-to limited buffer sizes. Setting this flag the csum will be done in SW on
-JUMBO frames::
-
-        int bugged_jumbo;
-
-12) Core has the embedded power module::
-
-        int pmt;
-

-        struct stmmac_txq_cfg tx_queues_cfg[MTL_MAX_TX_QUEUES];
-
-24) This callback is used for modifying some syscfg registers (on ST SoCs)
-according to the link speed negotiated by the physical layer::
-
-        void (*fix_mac_speed)(void *priv, unsigned int speed);
-
-25) Callbacks used for calling a custom initialization; This is sometimes
-necessary on some platforms (e.g. ST boxes) where the HW needs to have set
-some PIO lines or system cfg registers. init/exit callbacks should not use
-or modify platform data::
-
-        int (*init)(struct platform_device *pdev, void *priv);
-        void (*exit)(struct platform_device *pdev, void *priv);
-
-26) Perform HW setup of the bus. For example, on some ST platforms this field

-
-Device Tree Information
------------------------
-
-Please refer to the following document:
-Documentation/devicetree/bindings/net/snps,dwmac.yaml
-
-HW Capabilities
----------------
-
-Note that, starting from new chips, where it is available the HW capability
-register, many configurations are discovered at run-time for example to
-understand if EEE, HW csum, PTP, enhanced descriptor etc are actually
-available. As strategy adopted in this driver, the information from the HW
-capability register can replace what has been passed from the platform.
-
-Debug Information
-=================
-
-The driver exports many information i.e. internal statistics, debug
-information, MAC and DMA registers etc.
-
-These can be read in several ways depending on the type of the information
-actually needed.
-
-For example a user can be use the ethtool support to get statistics: e.g.
-using: ``ethtool -S ethX`` (that shows the Management counters (MMC) if
-supported) or sees the MAC/DMA registers: e.g. using: ``ethtool -d ethX``
-
-Compiling the Kernel with ``CONFIG_DEBUG_FS`` the driver will export the
-following debugfs entries:
-
- - ``descriptors_status``: To show the DMA TX/RX descriptor rings
- - ``dma_cap``: To show the HW Capabilities
-
-Developer can also use the ``debug`` module parameter to get further debug
-information (please see: NETIF Msg Level).
-
-Support
-=======
-
-If an issue is identified with the released source code on a supported kernel
-with a supported adapter, email the specific information related to the
-issue to netdev@vger.kernel.org

-
-Multiqueue & CBS & MQPRIO
-=========================
-
-
-The cpsw has 3 CBS shapers for each external ports. This document
-describes MQPRIO and CBS Qdisc offload configuration for cpsw driver
-based on examples. It potentially can be used in audio video bridging
-(AVB) and time sensitive networking (TSN).
-
-The following examples were tested on AM572x EVM and BBB boards.
-
-Test setup
-==========
-
-Under consideration two examples with AM572x EVM running cpsw driver
-in dual_emac mode.
-
-Several prerequisites:
-
-- TX queues must be rated starting from txq0 that has highest priority
-- Traffic classes are used starting from 0, that has highest priority
-- CBS shapers should be used with rated queues
-- The bandwidth for CBS shapers has to be set a little bit more then
-  potential incoming rate, thus, rate of all incoming tx queues has
-  to be a little less
-- Real rates can differ, due to discreetness
-- Map skb-priority to txq is not enough, also skb-priority to l2 prio
-  map has to be created with ip or vconfig tool
-- Any l2/socket prio (0 - 7) for classes can be used, but for
-  simplicity default values are used: 3 and 2
-- only 2 classes tested: A and B, but checked and can work with more,
-  maximum allowed 4, but only for 3 rate can be set.

-Texas Instruments CPSW switchdev based ethernet driver
-======================================================
-
-:Version: 2.0
-
-Port renaming
-=============
-
-On older udev versions renaming of ethX to swXpY will not be automatically
-supported
-
-In order to rename via udev::
-
-    ip -d link show dev sw0p1 | grep switchid
-
-    SUBSYSTEM=="net", ACTION=="add", ATTR{phys_switch_id}==<switchid>, \
-	    ATTR{phys_port_name}!="", NAME="sw0$attr{phys_port_name}"
-
-
-Dual mac mode
-=============
-
-- The new (cpsw_new.c) driver is operating in dual-emac mode by default, thus
-  working as 2 individual network interfaces. Main differences from legacy CPSW
-  driver are:
-
- - optimized promiscuous mode: The P0_UNI_FLOOD (both ports) is enabled in
-   addition to ALLMULTI (current port) instead of ALE_BYPASS.
-   So, Ports in promiscuous mode will keep possibility of mcast and vlan
-   filtering, which is provides significant benefits when ports are joined
-   to the same bridge, but without enabling "switch" mode, or to different
-   bridges.
- - learning disabled on ports as it make not too much sense for
-   segregated ports - no forwarding in HW.
- - enabled basic support for devlink.

-Devlink configuration parameters
-================================
-
-See Documentation/networking/devlink/ti-cpsw-switch.rst
-
-Bridging in dual mac mode
-=========================
-
-The dual_mac mode requires two vids to be reserved for internal purposes,
-which, by default, equal CPSW Port numbers. As result, bridge has to be
-configured in vlan unaware mode or default_pvid has to be adjusted::
-
-	ip link add name br0 type bridge
-	ip link set dev br0 type bridge vlan_filtering 0
-	echo 0 > /sys/class/net/br0/bridge/default_pvid
-	ip link set dev sw0p1 master br0
-	ip link set dev sw0p2 master br0
-
-or::
-
-	ip link add name br0 type bridge
-	ip link set dev br0 type bridge vlan_filtering 0
-	echo 100 > /sys/class/net/br0/bridge/default_pvid
-	ip link set dev br0 type bridge vlan_filtering 1
-	ip link set dev sw0p1 master br0
-	ip link set dev sw0p2 master br0
-
-Enabling "switch"
-=================
-
-The Switch mode can be enabled by configuring devlink driver parameter
-"switch_mode" to 1/true::
-
-	devlink dev param set platform/48484000.switch \
-	name switch_mode value 1 cmode runtime
-
-This can be done regardless of the state of Port's netdev devices - UP/DOWN, but
-Port's netdev devices have to be in UP before joining to the bridge to avoid
-overwriting of bridge configuration as CPSW switch driver copletly reloads its
-configuration when first Port changes its state to UP.
-
-When the both interfaces joined the bridge - CPSW switch driver will enable
-marking packets with offload_fwd_mark flag unless "ale_bypass=0"
-
-All configuration is implemented via switchdev API.
-
-Bridge setup
-============
-
-::
-
-	devlink dev param set platform/48484000.switch \
-	name switch_mode value 1 cmode runtime
-
-	ip link add name br0 type bridge
-	ip link set dev br0 type bridge ageing_time 1000
-	ip link set dev sw0p1 up
-	ip link set dev sw0p2 up
-	ip link set dev sw0p1 master br0
-	ip link set dev sw0p2 master br0
-
-	[*] bridge vlan add dev br0 vid 1 pvid untagged self
-
-	[*] if vlan_filtering=1. where default_pvid=1
-
-	Note. Steps [*] are mandatory.
-
-
-On/off STP
-==========
-
-::
-
-	ip link set dev BRDEV type bridge stp_state 1/0
-
-VLAN configuration
-==================
-
-::
-
-  bridge vlan add dev br0 vid 1 pvid untagged self <---- add cpu port to VLAN 1
-
-Note. This step is mandatory for bridge/default_pvid.
-
-Add extra VLANs
-===============
-
- 1. untagged::
-
-	bridge vlan add dev sw0p1 vid 100 pvid untagged master
-	bridge vlan add dev sw0p2 vid 100 pvid untagged master
-	bridge vlan add dev br0 vid 100 pvid untagged self <---- Add cpu port to VLAN100
-
- 2. tagged::
-
-	bridge vlan add dev sw0p1 vid 100 master
-	bridge vlan add dev sw0p2 vid 100 master
-	bridge vlan add dev br0 vid 100 pvid tagged self <---- Add cpu port to VLAN100
-
-FDBs
-----
-
-FDBs are automatically added on the appropriate switch port upon detection
-
-Manually adding FDBs::
-
-    bridge fdb add aa:bb:cc:dd:ee:ff dev sw0p1 master vlan 100
-    bridge fdb add aa:bb:cc:dd:ee:fe dev sw0p2 master <---- Add on all VLANs
-
-MDBs
-----
-
-MDBs are automatically added on the appropriate switch port upon detection
-
-Manually adding MDBs::
-
-  bridge mdb add dev br0 port sw0p1 grp 239.1.1.1 permanent vid 100
-  bridge mdb add dev br0 port sw0p1 grp 239.1.1.1 permanent <---- Add on all VLANs
-
-Multicast flooding
-==================
-CPU port mcast_flooding is always on
-
-Turning flooding on/off on swithch ports:
-bridge link set dev sw0p1 mcast_flood on/off
-
-Access and Trunk port
-=====================
-
-::
-
- bridge vlan add dev sw0p1 vid 100 pvid untagged master
- bridge vlan add dev sw0p2 vid 100 master
-
-
- bridge vlan add dev br0 vid 100 self
- ip link add link br0 name br0.100 type vlan id 100
-
-Note. Setting PVID on Bridge device itself working only for
-default VLAN (default_pvid).
-
-NFS
-===
-
-The only way for NFS to work is by chrooting to a minimal environment when
-switch configuration that will affect connectivity is needed.
-Assuming you are booting NFS with eth1 interface(the script is hacky and
-it's just there to prove NFS is doable).
-
-setup.sh::
-
-	#!/bin/sh
-	mkdir proc
-	mount -t proc none /proc
-	ifconfig br0  > /dev/null
-	if [ $? -ne 0 ]; then

-    Supported:

-    =========	=========	===========================================
-
-
-    Caveats:
-
-    I am not sure if 100BaseTX daughterboards (for those cards which
-    support such things) will work.  I haven't had any solid evidence
-    either way.
-
-    However, if a card supports 100BaseTx without requiring an add
-    on daughterboard, it should work with 100BaseTx.
-
-    The "Netelligent 10 T/2 PCI UTP/Coax" (b012) device is untested,
-    but I do not expect any problems.
-
-
-II. Driver Options
-==================
-
-	1. You can append debug=x to the end of the insmod line to get
-	   debug messages, where x is a bit field where the bits mean
-	   the following:
-
-	   ====		=====================================
-	   0x01		Turn on general debugging messages.
-	   0x02		Turn on receive debugging messages.
-	   0x04		Turn on transmit debugging messages.
-	   0x08		Turn on list debugging messages.
-	   ====		=====================================
-
-	2. You can append aui=1 to the end of the insmod line to cause
-	   the adapter to use the AUI interface instead of the 10 Base T
-	   interface.  This is also what to do if you want to use the BNC
-	   connector on a TLAN based device.  (Setting this option on a
-	   device that does not have an AUI/BNC connector will probably
-	   cause it to not function correctly.)
-
-	3. You can set duplex=1 to force half duplex, and duplex=2 to
-	   force full duplex.
-
-	4. You can set speed=10 to force 10Mbs operation, and speed=100
-	   to force 100Mbs operation. (I'm not sure what will happen
-	   if a card which only supports 10Mbs is forced into 100Mbs
-	   mode.)
-
-	5. You have to use speed=X duplex=Y together now. If you just
-	   do "insmod tlan.o speed=100" the driver will do Auto-Neg.
-	   To force a 10Mbps Half-Duplex link do "insmod tlan.o speed=10
-	   duplex=1".
-
-	6. If the driver is built into the kernel, you can use the 3rd
-	   and 4th parameters to set aui and debug respectively.  For
-	   example::
-
-		ether=0,0,0x1,0x7,eth0
-
-	   This sets aui to 0x1 and debug to 0x7, assuming eth0 is a
-	   supported TLAN device.
-
-	   The bits in the third byte are assigned as follows:
-
-		====   ===============
-		0x01   aui
-		0x02   use half duplex
-		0x04   use full duplex
-		0x08   use 10BaseT
-		0x10   use 100BaseTx
-		====   ===============
-
-	   You also need to set both speed and duplex settings when forcing
-	   speeds with kernel-parameters.
-	   ether=0,0,0x12,0,eth0 will force link to 100Mbps Half-Duplex.
-
-	7. If you have more than one tlan adapter in your system, you can
-	   use the above options on a per adapter basis. To force a 100Mbit/HD
-	   link with your eth1 adapter use::
-
-		insmod tlan speed=0,100 duplex=0,1
-
-	   Now eth0 will use auto-neg and eth1 will be forced to 100Mbit/HD.
-	   Note that the tlan driver supports a maximum of 8 adapters.
-
-
-III. Things to try if you have problems
-=======================================
-
-	1. Make sure your card's PCI id is among those listed in
-	   section I, above.
-	2. Make sure routing is correct.
-	3. Try forcing different speed/duplex settings
-
-
-There is also a tlan mailing list which you can join by sending "subscribe tlan"
-in the body of an email to majordomo@vuser.vu.union.edu.
-
-There is also a tlan website at http://www.compaq.com

-===========================
-The Spidernet Device Driver
-===========================
-
-Written by Linas Vepstas <linas@austin.ibm.com>
-
-Version of 7 June 2007
-
-Abstract
-========
-This document sketches the structure of portions of the spidernet
-device driver in the Linux kernel tree. The spidernet is a gigabit
-ethernet device built into the Toshiba southbridge commonly used
-in the SONY Playstation 3 and the IBM QS20 Cell blade.
-
-The Structure of the RX Ring.
-=============================
-The receive (RX) ring is a circular linked list of RX descriptors,
-together with three pointers into the ring that are used to manage its
-contents.
-
-The elements of the ring are called "descriptors" or "descrs"; they
-describe the received data. This includes a pointer to a buffer
-containing the received data, the buffer size, and various status bits.
-
-There are three primary states that a descriptor can be in: "empty",
-"full" and "not-in-use".  An "empty" or "ready" descriptor is ready
-to receive data from the hardware. A "full" descriptor has data in it,
-and is waiting to be emptied and processed by the OS. A "not-in-use"
-descriptor is neither empty or full; it is simply not ready. It may
-not even have a data buffer in it, or is otherwise unusable.
-
-During normal operation, on device startup, the OS (specifically, the
-spidernet device driver) allocates a set of RX descriptors and RX
-buffers. These are all marked "empty", ready to receive data. This
-ring is handed off to the hardware, which sequentially fills in the
-buffers, and marks them "full". The OS follows up, taking the full
-buffers, processing them, and re-marking them empty.
-
-This filling and emptying is managed by three pointers, the "head"
-and "tail" pointers, managed by the OS, and a hardware current
-descriptor pointer (GDACTDPA). The GDACTDPA points at the descr
-currently being filled. When this descr is filled, the hardware
-marks it full, and advances the GDACTDPA by one.  Thus, when there is
-flowing RX traffic, every descr behind it should be marked "full",
-and everything in front of it should be "empty".  If the hardware
-discovers that the current descr is not empty, it will signal an
-interrupt, and halt processing.
-
-The tail pointer tails or trails the hardware pointer. When the
-hardware is ahead, the tail pointer will be pointing at a "full"
-descr. The OS will process this descr, and then mark it "not-in-use",
-and advance the tail pointer.  Thus, when there is flowing RX traffic,
-all of the descrs in front of the tail pointer should be "full", and
-all of those behind it should be "not-in-use". When RX traffic is not
-flowing, then the tail pointer can catch up to the hardware pointer.
-The OS will then note that the current tail is "empty", and halt
-processing.
-
-The head pointer (somewhat mis-named) follows after the tail pointer.
-When traffic is flowing, then the head pointer will be pointing at
-a "not-in-use" descr. The OS will perform various housekeeping duties
-on this descr. This includes allocating a new data buffer and
-dma-mapping it so as to make it visible to the hardware. The OS will
-then mark the descr as "empty", ready to receive data. Thus, when there
-is flowing RX traffic, everything in front of the head pointer should
-be "not-in-use", and everything behind it should be "empty". If no
-RX traffic is flowing, then the head pointer can catch up to the tail
-pointer, at which point the OS will notice that the head descr is
-"empty", and it will halt processing.
-
-Thus, in an idle system, the GDACTDPA, tail and head pointers will
-all be pointing at the same descr, which should be "empty". All of the
-other descrs in the ring should be "empty" as well.
-
-The show_rx_chain() routine will print out the locations of the
-GDACTDPA, tail and head pointers. It will also summarize the contents
-of the ring, starting at the tail pointer, and listing the status
-of the descrs that follow.
-
-A typical example of the output, for a nearly idle system, might be::
-
-    net eth1: Total number of descrs=256
-    net eth1: Chain tail located at descr=20
-    net eth1: Chain head is at 20
-    net eth1: HW curr desc (GDACTDPA) is at 21
-    net eth1: Have 1 descrs with stat=x40800101
-    net eth1: HW next desc (GDACNEXTDA) is at 22
-    net eth1: Last 255 descrs with stat=xa0800000
-
-In the above, the hardware has filled in one descr, number 20. Both
-head and tail are pointing at 20, because it has not yet been emptied.
-Meanwhile, hw is pointing at 21, which is free.
-
-The "Have nnn decrs" refers to the descr starting at the tail: in this
-case, nnn=1 descr, starting at descr 20. The "Last nnn descrs" refers
-to all of the rest of the descrs, from the last status change. The "nnn"
-is a count of how many descrs have exactly the same status.
-
-The status x4... corresponds to "full" and status xa... corresponds
-to "empty". The actual value printed is RXCOMST_A.
-
-In the device driver source code, a different set of names are
-used for these same concepts, so that::
-
-    "empty" == SPIDER_NET_DESCR_CARDOWNED == 0xa
-    "full"  == SPIDER_NET_DESCR_FRAME_END == 0x4
-    "not in use" == SPIDER_NET_DESCR_NOT_IN_USE == 0xf
-
-
-The RX RAM full bug/feature
-===========================
-
-As long as the OS can empty out the RX buffers at a rate faster than
-the hardware can fill them, there is no problem. If, for some reason,
-the OS fails to empty the RX ring fast enough, the hardware GDACTDPA
-pointer will catch up to the head, notice the not-empty condition,
-ad stop. However, RX packets may still continue arriving on the wire.
-The spidernet chip can save some limited number of these in local RAM.
-When this local ram fills up, the spider chip will issue an interrupt
-indicating this (GHIINT0STS will show ERRINT, and the GRMFLLINT bit
-will be set in GHIINT1STS).  When the RX ram full condition occurs,
-a certain bug/feature is triggered that has to be specially handled.
-This section describes the special handling for this condition.
-
-When the OS finally has a chance to run, it will empty out the RX ring.
-In particular, it will clear the descriptor on which the hardware had
-stopped. However, once the hardware has decided that a certain
-descriptor is invalid, it will not restart at that descriptor; instead
-it will restart at the next descr. This potentially will lead to a
-deadlock condition, as the tail pointer will be pointing at this descr,
-which, from the OS point of view, is empty; the OS will be waiting for
-this descr to be filled. However, the hardware has skipped this descr,
-and is filling the next descrs. Since the OS doesn't see this, there
-is a potential deadlock, with the OS waiting for one descr to fill,
-while the hardware is waiting for a different set of descrs to become
-empty.
-
-A call to show_rx_chain() at this point indicates the nature of the
-problem. A typical print when the network is hung shows the following::
-
-    net eth1: Spider RX RAM full, incoming packets might be discarded!
-    net eth1: Total number of descrs=256
-    net eth1: Chain tail located at descr=255
-    net eth1: Chain head is at 255
-    net eth1: HW curr desc (GDACTDPA) is at 0
-    net eth1: Have 1 descrs with stat=xa0800000
-    net eth1: HW next desc (GDACNEXTDA) is at 1
-    net eth1: Have 127 descrs with stat=x40800101
-    net eth1: Have 1 descrs with stat=x40800001
-    net eth1: Have 126 descrs with stat=x40800101
-    net eth1: Last 1 descrs with stat=xa0800000
-
-Both the tail and head pointers are pointing at descr 255, which is
-marked xa... which is "empty". Thus, from the OS point of view, there
-is nothing to be done. In particular, there is the implicit assumption
-that everything in front of the "empty" descr must surely also be empty,
-as explained in the last section. The OS is waiting for descr 255 to
-become non-empty, which, in this case, will never happen.
-
-The HW pointer is at descr 0. This descr is marked 0x4.. or "full".
-Since its already full, the hardware can do nothing more, and thus has
-halted processing. Notice that descrs 0 through 254 are all marked
-"full", while descr 254 and 255 are empty. (The "Last 1 descrs" is
-descr 254, since tail was at 255.) Thus, the system is deadlocked,
-and there can be no forward progress; the OS thinks there's nothing
-to do, and the hardware has nowhere to put incoming data.
-
-This bug/feature is worked around with the spider_net_resync_head_ptr()
-routine. When the driver receives RX interrupts, but an examination
-of the RX chain seems to show it is empty, then it is probable that
-the hardware has skipped a descr or two (sometimes dozens under heavy
-network conditions). The spider_net_resync_head_ptr() subroutine will
-search the ring for the next full descr, and the driver will resume
-operations there.  Since this will leave "holes" in the ring, there
-is also a spider_net_resync_tail_ptr() that will skip over such holes.
-
-As of this writing, the spider_net_resync() strategy seems to work very
-well, even under heavy network loads.
-
-
-The TX ring
-===========
-The TX ring uses a low-watermark interrupt scheme to make sure that
-the TX queue is appropriately serviced for large packet sizes.
-
-For packet sizes greater than about 1KBytes, the kernel can fill
-the TX ring quicker than the device can drain it. Once the ring
-is full, the netdev is stopped. When there is room in the ring,
-the netdev needs to be reawakened, so that more TX packets are placed
-in the ring. The hardware can empty the ring about four times per jiffy,
-so its not appropriate to wait for the poll routine to refill, since
-the poll routine runs only once per jiffy.  The low-watermark mechanism
-marks a descr about 1/4th of the way from the bottom of the queue, so
-that an interrupt is generated when the descr is processed. This
-interrupt wakes up the netdev, which can then refill the queue.
-For large packets, this mechanism generates a relatively small number
-of interrupts, about 1K/sec. For smaller packets, this will drop to zero
-interrupts, as the hardware can empty the queue faster than the kernel
-can fill it.

+0. IMPORTANT INFORMATION BEFORE USING THIS DRIVER
+=================================================
+
+Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!
+
+Intel wireless LAN adapters are engineered, manufactured, tested, and
+quality checked to ensure that they meet all necessary local and
+governmental regulatory agency requirements for the regions that they
+are designated and/or marked to ship into. Since wireless LANs are
+generally unlicensed devices that share spectrum with radars,
+satellites, and other licensed and unlicensed devices, it is sometimes
+necessary to dynamically detect, avoid, and limit usage to avoid
+interference with these devices. In many instances Intel is required to
+provide test data to prove regional and local compliance to regional and
+governmental regulations before certification or approval to use the
+product is granted. Intel's wireless LAN's EEPROM, firmware, and
+software driver are designed to carefully control parameters that affect
+radio operation and to ensure electromagnetic compliance (EMC). These
+parameters include, without limitation, RF power, spectrum usage,
+channel scanning, and human exposure.
+
+For these reasons Intel cannot permit any manipulation by third parties
+of the software provided in binary format with the wireless WLAN
+adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
+patches, utilities, or code with the Intel wireless LAN adapters that
+have been manipulated by an unauthorized party (i.e., patches,
+utilities, or code (including open source code modifications) which have
+not been validated by Intel), (i) you will be solely responsible for
+ensuring the regulatory compliance of the products, (ii) Intel will bear
+no liability, under any theory of liability for any issues associated
+with the modified products, including without limitation, claims under
+the warranty and/or issues arising from regulatory non-compliance, and
+(iii) Intel will not provide or be required to assist in providing
+support to any third parties for such modified products.
+
+Note: Many regulatory agencies consider Wireless LAN adapters to be
+modules, and accordingly, condition system-level regulatory approval
+upon receipt and review of test data documenting that the antennas and
+system configuration do not cause the EMC and radio operation to be
+non-compliant.
+
+The drivers available for download from SourceForge are provided as a
+part of a development project.  Conformance to local regulatory
+requirements is the responsibility of the individual developer.  As
+such, if you are interested in deploying or shipping a driver as part of
+solution intended to be used for purposes other than development, please
+obtain a tested driver from Intel Customer Support at:
+
+http://www.intel.com/support/wireless/sb/CS-006408.htm
+
+1. Introduction
+===============
+
+This document provides a brief overview of the features supported by the
+IPW2100 driver project.  The main project website, where the latest
+development version of the driver can be found, is:
+
+	http://ipw2100.sourceforge.net
+
+There you can find the not only the latest releases, but also information about
+potential fixes and patches, as well as links to the development mailing list
+for the driver project.
+
+
+2. Release git-1.1.5 Current Supported Features
+===============================================
+
+- Managed (BSS) and Ad-Hoc (IBSS)
+- WEP (shared key and open)
+- Wireless Tools support
+- 802.1x (tested with XSupplicant 1.0.1)
+
+Enabled (but not supported) features:
+- Monitor/RFMon mode
+- WPA/WPA2
+
+The distinction between officially supported and enabled is a reflection
+on the amount of validation and interoperability testing that has been
+performed on a given feature.
+
+
+3. Command Line Parameters
+==========================
+
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax::
+
+	modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
+
+For example, to disable the radio on driver loading, enter:
+
+	modprobe ipw2100 disable=1
+
+The ipw2100 driver supports the following module parameters:
+
+=========	==============	============  ==============================
+Name		Value		Example       Meaning
+=========	==============	============  ==============================
+debug		0x0-0xffffffff	debug=1024    Debug level set to 1024
+mode		0,1,2		mode=1        AdHoc
+channel		int		channel=3     Only valid in AdHoc or Monitor
+associate	boolean		associate=0   Do NOT auto associate
+disable		boolean		disable=1     Do not power the HW
+=========	==============	============  ==============================
+
+
+4. Sysfs Helper Files
+=====================
+
+There are several ways to control the behavior of the driver.  Many of the
+general capabilities are exposed through the Wireless Tools (iwconfig).  There
+are a few capabilities that are exposed through entries in the Linux Sysfs.
+
+
+**Driver Level**
+
+For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
+
+  debug_level
+	This controls the same global as the 'debug' module parameter.  For
+	information on the various debugging levels available, run the 'dvals'
+	script found in the driver source directory.
+
+	.. note::
+
+	      'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn on.
+
+**Device Level**
+
+For the device level files look in::
+
+	/sys/bus/pci/drivers/ipw2100/{PCI-ID}/
+
+For example::
+
+	/sys/bus/pci/drivers/ipw2100/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/drivers/ipw2100:
+
+  rf_kill
+	read
+
+	==  =========================================
+	0   RF kill not enabled (radio on)
+	1   SW based RF kill active (radio off)
+	2   HW based RF kill active (radio off)
+	3   Both HW and SW RF kill active (radio off)
+	==  =========================================
+
+	write
+
+	==  ==================================================
+	0   If SW based RF kill active, turn the radio back on
+	1   If radio is on, activate SW based RF kill
+	==  ==================================================
+
+	.. note::
+
+	   If you enable the SW based RF kill and then toggle the HW
+	   based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+
+
+5. Radio Kill Switch
+====================
+
+Most laptops provide the ability for the user to physically disable the radio.
+Some vendors have implemented this as a physical switch that requires no
+software to turn the radio off and on.  On other laptops, however, the switch
+is controlled through a button being pressed and a software driver then making
+calls to turn the radio off and on.  This is referred to as a "software based
+RF kill switch"
+
+See the Sysfs helper file 'rf_kill' for determining the state of the RF switch
+on your system.
+
+
+6. Dynamic Firmware
+===================
+
+As the firmware is licensed under a restricted use license, it can not be
+included within the kernel sources.  To enable the IPW2100 you will need a
+firmware image to load into the wireless NIC's processors.
+
+You can obtain these images from <http://ipw2100.sf.net/firmware.php>.
+
+See INSTALL for instructions on installing the firmware.
+
+
+7. Power Management
+===================
+
+The IPW2100 supports the configuration of the Power Save Protocol
+through a private wireless extension interface.  The IPW2100 supports
+the following different modes:
+
+	===	===========================================================
+	off	No power management.  Radio is always on.
+	on	Automatic power management
+	1-5	Different levels of power management.  The higher the
+		number the greater the power savings, but with an impact to
+		packet latencies.
+	===	===========================================================
+
+Power management works by powering down the radio after a certain
+interval of time has passed where no packets are passed through the
+radio.  Once powered down, the radio remains in that state for a given
+period of time.  For higher power savings, the interval between last
+packet processed to sleep is shorter and the sleep period is longer.
+
+When the radio is asleep, the access point sending data to the station
+must buffer packets at the AP until the station wakes up and requests
+any buffered packets.  If you have an AP that does not correctly support
+the PSP protocol you may experience packet loss or very poor performance
+while power management is enabled.  If this is the case, you will need
+to try and find a firmware update for your AP, or disable power
+management (via ``iwconfig eth1 power off``)
+
+To configure the power level on the IPW2100 you use a combination of
+iwconfig and iwpriv.  iwconfig is used to turn power management on, off,
+and set it to auto.
+
+	=========================  ====================================
+	iwconfig eth1 power off    Disables radio power down
+	iwconfig eth1 power on     Enables radio power management to
+				   last set level (defaults to AUTO)
+	iwpriv eth1 set_power 0    Sets power level to AUTO and enables
+				   power management if not previously
+				   enabled.
+	iwpriv eth1 set_power 1-5  Set the power level as specified,
+				   enabling power management if not
+				   previously enabled.
+	=========================  ====================================
+
+You can view the current power level setting via::
+
+	iwpriv eth1 get_power
+
+It will return the current period or timeout that is configured as a string
+in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
+time after packet processing), yyyy is the period to sleep (amount of time to
+wait before powering the radio and querying the access point for buffered
+packets), and z is the 'power level'.  If power management is turned off the
+xxxx/yyyy will be replaced with 'off' -- the level reported will be the active
+level if `iwconfig eth1 power on` is invoked.

+=================================================
+
+Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!
+
+Intel wireless LAN adapters are engineered, manufactured, tested, and
+quality checked to ensure that they meet all necessary local and
+governmental regulatory agency requirements for the regions that they
+are designated and/or marked to ship into. Since wireless LANs are
+generally unlicensed devices that share spectrum with radars,
+satellites, and other licensed and unlicensed devices, it is sometimes
+necessary to dynamically detect, avoid, and limit usage to avoid
+interference with these devices. In many instances Intel is required to
+provide test data to prove regional and local compliance to regional and
+governmental regulations before certification or approval to use the
+product is granted. Intel's wireless LAN's EEPROM, firmware, and
+software driver are designed to carefully control parameters that affect
+radio operation and to ensure electromagnetic compliance (EMC). These
+parameters include, without limitation, RF power, spectrum usage,
+channel scanning, and human exposure.
+
+For these reasons Intel cannot permit any manipulation by third parties
+of the software provided in binary format with the wireless WLAN
+adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
+patches, utilities, or code with the Intel wireless LAN adapters that
+have been manipulated by an unauthorized party (i.e., patches,
+utilities, or code (including open source code modifications) which have
+not been validated by Intel), (i) you will be solely responsible for
+ensuring the regulatory compliance of the products, (ii) Intel will bear
+no liability, under any theory of liability for any issues associated
+with the modified products, including without limitation, claims under
+the warranty and/or issues arising from regulatory non-compliance, and
+(iii) Intel will not provide or be required to assist in providing
+support to any third parties for such modified products.
+
+Note: Many regulatory agencies consider Wireless LAN adapters to be
+modules, and accordingly, condition system-level regulatory approval
+upon receipt and review of test data documenting that the antennas and
+system configuration do not cause the EMC and radio operation to be
+non-compliant.
+
+The drivers available for download from SourceForge are provided as a
+part of a development project.  Conformance to local regulatory
+requirements is the responsibility of the individual developer.  As
+such, if you are interested in deploying or shipping a driver as part of
+solution intended to be used for purposes other than development, please
+obtain a tested driver from Intel Customer Support at:
+
+http://support.intel.com
+
+
+1. Introduction
+===============
+
+The following sections attempt to provide a brief introduction to using
+the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
+
+This document is not meant to be a comprehensive manual on
+understanding or using wireless technologies, but should be sufficient
+to get you moving without wires on Linux.
+
+For information on building and installing the driver, see the INSTALL
+file.
+
+
+1.1. Overview of Features
+-------------------------
+The current release (1.1.2) supports the following features:
+
++ BSS mode (Infrastructure, Managed)
++ IBSS mode (Ad-Hoc)
++ WEP (OPEN and SHARED KEY mode)
++ 802.1x EAP via wpa_supplicant and xsupplicant
++ Wireless Extension support
++ Full B and G rate support (2200 and 2915)
++ Full A rate support (2915 only)
++ Transmit power control
++ S state support (ACPI suspend/resume)
+
+The following features are currently enabled, but not officially
+supported:
+
++ WPA
++ long/short preamble support
++ Monitor mode (aka RFMon)
+
+The distinction between officially supported and enabled is a reflection
+on the amount of validation and interoperability testing that has been
+performed on a given feature.
+
+
+
+1.2. Command Line Parameters
+----------------------------
+
+Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless
+2915ABG Driver for Linux allows configuration options to be provided
+as module parameters.  The most common way to specify a module parameter
+is via the command line.
+
+The general form is::
+
+    % modprobe ipw2200 parameter=value
+
+Where the supported parameter are:
+
+  associate
+	Set to 0 to disable the auto scan-and-associate functionality of the
+	driver.  If disabled, the driver will not attempt to scan
+	for and associate to a network until it has been configured with
+	one or more properties for the target network, for example configuring
+	the network SSID.  Default is 0 (do not auto-associate)
+
+	Example: % modprobe ipw2200 associate=0
+
+  auto_create
+	Set to 0 to disable the auto creation of an Ad-Hoc network
+	matching the channel and network name parameters provided.
+	Default is 1.
+
+  channel
+	channel number for association.  The normal method for setting
+	the channel would be to use the standard wireless tools
+	(i.e. `iwconfig eth1 channel 10`), but it is useful sometimes
+	to set this while debugging.  Channel 0 means 'ANY'
+
+  debug
+	If using a debug build, this is used to control the amount of debug
+	info is logged.  See the 'dvals' and 'load' script for more info on
+	how to use this (the dvals and load scripts are provided as part
+	of the ipw2200 development snapshot releases available from the
+	SourceForge project at http://ipw2200.sf.net)
+
+  led
+	Can be used to turn on experimental LED code.
+	0 = Off, 1 = On.  Default is 1.
+
+  mode
+	Can be used to set the default mode of the adapter.
+	0 = Managed, 1 = Ad-Hoc, 2 = Monitor
+
+
+1.3. Wireless Extension Private Methods
+---------------------------------------
+
+As an interface designed to handle generic hardware, there are certain
+capabilities not exposed through the normal Wireless Tool interface.  As
+such, a provision is provided for a driver to declare custom, or
+private, methods.  The Intel(R) PRO/Wireless 2915ABG Driver for Linux
+defines several of these to configure various settings.
+
+The general form of using the private wireless methods is::
+
+	% iwpriv $IFNAME method parameters
+
+Where $IFNAME is the interface name the device is registered with
+(typically eth1, customized via one of the various network interface
+name managers, such as ifrename)
+
+The supported private methods are:
+
+  get_mode
+	Can be used to report out which IEEE mode the driver is
+	configured to support.  Example:
+
+	% iwpriv eth1 get_mode
+	eth1	get_mode:802.11bg (6)
+
+  set_mode
+	Can be used to configure which IEEE mode the driver will
+	support.
+
+	Usage::
+
+	    % iwpriv eth1 set_mode {mode}
+
+	Where {mode} is a number in the range 1-7:
+
+	==	=====================
+	1	802.11a (2915 only)
+	2	802.11b
+	3	802.11ab (2915 only)
+	4	802.11g
+	5	802.11ag (2915 only)
+	6	802.11bg
+	7	802.11abg (2915 only)
+	==	=====================
+
+  get_preamble
+	Can be used to report configuration of preamble length.
+
+  set_preamble
+	Can be used to set the configuration of preamble length:
+
+	Usage::
+
+	    % iwpriv eth1 set_preamble {mode}
+
+	Where {mode} is one of:
+
+	==	========================================
+	1	Long preamble only
+	0	Auto (long or short based on connection)
+	==	========================================
+
+
+1.4. Sysfs Helper Files
+-----------------------
+
+The Linux kernel provides a pseudo file system that can be used to
+access various components of the operating system.  The Intel(R)
+PRO/Wireless 2915ABG Driver for Linux exposes several configuration
+parameters through this mechanism.
+
+An entry in the sysfs can support reading and/or writing.  You can
+typically query the contents of a sysfs entry through the use of cat,
+and can set the contents via echo.  For example::
+
+    % cat /sys/bus/pci/drivers/ipw2200/debug_level
+
+Will report the current debug level of the driver's logging subsystem
+(only available if CONFIG_IPW2200_DEBUG was configured when the driver
+was built).
+
+You can set the debug level via::
+
+    % echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
+
+Where $VALUE would be a number in the case of this sysfs entry.  The
+input to sysfs files does not have to be a number.  For example, the
+firmware loader used by hotplug utilizes sysfs entries for transferring
+the firmware image from user space into the driver.
+
+The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries
+at two levels -- driver level, which apply to all instances of the driver
+(in the event that there are more than one device installed) and device
+level, which applies only to the single specific instance.
+
+
+1.4.1 Driver Level Sysfs Helper Files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
+
+  debug_level
+	This controls the same global as the 'debug' module parameter
+
+
+
+1.4.2 Device Level Sysfs Helper Files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For the device level files, look in::
+
+	/sys/bus/pci/drivers/ipw2200/{PCI-ID}/
+
+For example:::
+
+	/sys/bus/pci/drivers/ipw2200/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/drivers/ipw2200:
+
+  rf_kill
+	read -
+
+	==  =========================================
+	0   RF kill not enabled (radio on)
+	1   SW based RF kill active (radio off)
+	2   HW based RF kill active (radio off)
+	3   Both HW and SW RF kill active (radio off)
+	==  =========================================
+
+	write -
+
+	==  ==================================================
+	0   If SW based RF kill active, turn the radio back on
+	1   If radio is on, activate SW based RF kill
+	==  ==================================================
+
+	.. note::
+
+	   If you enable the SW based RF kill and then toggle the HW
+	   based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+
+  ucode
+	read-only access to the ucode version number
+
+  led
+	read -
+
+	==  =================
+	0   LED code disabled
+	1   LED code enabled
+	==  =================
+
+	write -
+
+	==  ================
+	0   Disable LED code
+	1   Enable LED code
+	==  ================
+
+
+	.. note::
+
+	   The LED code has been reported to hang some systems when
+	   running ifconfig and is therefore disabled by default.
+
+
+1.5. Supported channels
+-----------------------
+
+Upon loading the Intel(R) PRO/Wireless 2915ABG Driver for Linux, a
+message stating the detected geography code and the number of 802.11
+channels supported by the card will be displayed in the log.
+
+The geography code corresponds to a regulatory domain as shown in the
+table below.
+
+	+------+----------------------------+--------------------+
+	|      |			    | Supported channels |

+
+2.  Ad-Hoc Networking
+=====================
+
+When using a device in an Ad-Hoc network, it is useful to understand the
+sequence and requirements for the driver to be able to create, join, or
+merge networks.
+
+The following attempts to provide enough information so that you can
+have a consistent experience while using the driver as a member of an
+Ad-Hoc network.
+
+2.1. Joining an Ad-Hoc Network
+------------------------------
+
+The easiest way to get onto an Ad-Hoc network is to join one that
+already exists.
+
+2.2. Creating an Ad-Hoc Network
+-------------------------------
+
+An Ad-Hoc networks is created using the syntax of the Wireless tool.
+
+For Example:
+iwconfig eth1 mode ad-hoc essid testing channel 2
+
+2.3. Merging Ad-Hoc Networks
+----------------------------
+
+
+3. Interaction with Wireless Tools
+==================================
+
+3.1 iwconfig mode
+-----------------
+
+When configuring the mode of the adapter, all run-time configured parameters
+are reset to the value used when the module was loaded.  This includes
+channels, rates, ESSID, etc.
+
+3.2 iwconfig sens
+-----------------
+
+The 'iwconfig ethX sens XX' command will not set the signal sensitivity
+threshold, as described in iwconfig documentation, but rather the number
+of consecutive missed beacons that will trigger handover, i.e. roaming
+to another access point. At the same time, it will set the disassociation
+threshold to 3 times the given value.
+
+
+4.  About the Version Numbers
+=============================
+
+Due to the nature of open source development projects, there are
+frequently changes being incorporated that have not gone through
+a complete validation process.  These changes are incorporated into
+development snapshot releases.
+
+Releases are numbered with a three level scheme:
+
+	major.minor.development
+
+Any version where the 'development' portion is 0 (for example
+1.0.0, 1.1.0, etc.) indicates a stable version that will be made
+available for kernel inclusion.
+
+Any version where the 'development' portion is not a 0 (for
+example 1.0.1, 1.1.5, etc.) indicates a development version that is
+being made available for testing and cutting edge users.  The stability
+and functionality of the development releases are not know.  We make
+efforts to try and keep all snapshots reasonably stable, but due to the
+frequency of their release, and the desire to get those releases
+available as quickly as possible, unknown anomalies should be expected.
+
+The major version number will be incremented when significant changes
+are made to the driver.  Currently, there are no major changes planned.
+
+5. Firmware installation
+========================
+
+The driver requires a firmware image, download it and extract the
+files under /lib/firmware (or wherever your hotplug's firmware.agent
+will look for firmware files)
+
+The firmware can be downloaded from the following URL:
+
+    http://ipw2200.sf.net/

+SCC.C - Linux driver for Z8530 based HDLC cards for AX.25
+=========================================================
+
+
+This is a subset of the documentation. To use this driver you MUST have the
+full package from:
+
+Internet:
+
+    1. ftp://ftp.ccac.rwth-aachen.de/pub/jr/z8530drv-utils_3.0-3.tar.gz
+
+    2. ftp://ftp.pspt.fi/pub/ham/linux/ax25/z8530drv-utils_3.0-3.tar.gz
+
+Please note that the information in this document may be hopelessly outdated.
+A new version of the documentation, along with links to other important
+Linux Kernel AX.25 documentation and programs, is available on
+http://yaina.de/jreuter

+
+1. Initialization of the driver
+===============================
+
+To use the driver, 3 steps must be performed:
+
+     1. if compiled as module: loading the module
+     2. Setup of hardware, MODEM and KISS parameters with sccinit
+     3. Attach each channel to the Linux kernel AX.25 with "ifconfig"
+
+Unlike the versions below 2.4 this driver is a real network device
+driver. If you want to run xNOS instead of our fine kernel AX.25
+use a 2.x version (available from above sites) or read the
+AX.25-HOWTO on how to emulate a KISS TNC on network device drivers.
+
+
+1.1 Loading the module
+======================
+
+(If you're going to compile the driver as a part of the kernel image,
+ skip this chapter and continue with 1.2)
+
+Before you can use a module, you'll have to load it with::
+
+	insmod scc.o
+
+please read 'man insmod' that comes with module-init-tools.
+
+You should include the insmod in one of the /etc/rc.d/rc.* files,
+and don't forget to insert a call of sccinit after that. It
+will read your /etc/z8530drv.conf.
+
+1.2. /etc/z8530drv.conf
+=======================
+
+To setup all parameters you must run /sbin/sccinit from one
+of your rc.*-files. This has to be done BEFORE you can
+"ifconfig" an interface. Sccinit reads the file /etc/z8530drv.conf
+and sets the hardware, MODEM and KISS parameters. A sample file is
+delivered with this package. Change it to your needs.
+
+The file itself consists of two main sections.
+
+1.2.1 configuration of hardware parameters
+==========================================
+
+The hardware setup section defines the following parameters for each
+Z8530::
+
+    chip    1
+    data_a  0x300                   # data port A
+    ctrl_a  0x304                   # control port A
+    data_b  0x301                   # data port B
+    ctrl_b  0x305                   # control port B
+    irq     5                       # IRQ No. 5
+    pclock  4915200                 # clock
+    board   BAYCOM                  # hardware type
+    escc    no                      # enhanced SCC chip? (8580/85180/85280)
+    vector  0                       # latch for interrupt vector
+    special no                      # address of special function register
+    option  0                       # option to set via sfr
+
+
+chip
+	- this is just a delimiter to make sccinit a bit simpler to
+	  program. A parameter has no effect.
+
+data_a
+	- the address of the data port A of this Z8530 (needed)
+ctrl_a
+	- the address of the control port A (needed)
+data_b
+	- the address of the data port B (needed)
+ctrl_b
+	- the address of the control port B (needed)
+
+irq
+	- the used IRQ for this chip. Different chips can use different
+	  IRQs or the same. If they share an interrupt, it needs to be
+	  specified within one chip-definition only.
+
+pclock  - the clock at the PCLK pin of the Z8530 (option, 4915200 is
+	  default), measured in Hertz
+
+board
+	- the "type" of the board:
+
+	   =======================  ========
+	   SCC type                 value
+	   =======================  ========
+	   PA0HZP SCC card          PA0HZP
+	   EAGLE card               EAGLE
+	   PC100 card               PC100
+	   PRIMUS-PC (DG9BL) card   PRIMUS
+	   BayCom (U)SCC card       BAYCOM
+	   =======================  ========
+
+escc
+	- if you want support for ESCC chips (8580, 85180, 85280), set
+	  this to "yes" (option, defaults to "no")
+
+vector
+	- address of the vector latch (aka "intack port") for PA0HZP
+	  cards. There can be only one vector latch for all chips!
+	  (option, defaults to 0)
+
+special
+	- address of the special function register on several cards.
+	  (option, defaults to 0)
+
+option  - The value you write into that register (option, default is 0)
+
+You can specify up to four chips (8 channels). If this is not enough,
+just change::
+
+	#define MAXSCC 4
+
+to a higher value.
+
+Example for the BAYCOM USCC:
+----------------------------
+
+::
+
+	chip    1
+	data_a  0x300                   # data port A
+	ctrl_a  0x304                   # control port A
+	data_b  0x301                   # data port B
+	ctrl_b  0x305                   # control port B
+	irq     5                       # IRQ No. 5 (#)
+	board   BAYCOM                  # hardware type (*)
+	#
+	# SCC chip 2
+	#
+	chip    2
+	data_a  0x302
+	ctrl_a  0x306
+	data_b  0x303
+	ctrl_b  0x307
+	board   BAYCOM
+
+An example for a PA0HZP card:
+-----------------------------
+
+::
+
+	chip 1
+	data_a 0x153
+	data_b 0x151
+	ctrl_a 0x152
+	ctrl_b 0x150
+	irq 9
+	pclock 4915200
+	board PA0HZP
+	vector 0x168
+	escc no
+	#
+	#
+	#
+	chip 2
+	data_a 0x157
+	data_b 0x155
+	ctrl_a 0x156
+	ctrl_b 0x154
+	irq 9
+	pclock 4915200
+	board PA0HZP
+	vector 0x168
+	escc no
+
+A DRSI would should probably work with this:
+--------------------------------------------
+(actually: two DRSI cards...)
+
+::
+
+	chip 1
+	data_a 0x303
+	data_b 0x301
+	ctrl_a 0x302
+	ctrl_b 0x300
+	irq 7
+	pclock 4915200
+	board DRSI
+	escc no
+	#
+	#
+	#
+	chip 2
+	data_a 0x313
+	data_b 0x311
+	ctrl_a 0x312
+	ctrl_b 0x310
+	irq 7
+	pclock 4915200
+	board DRSI
+	escc no
+
+Note that you cannot use the on-board baudrate generator off DRSI
+cards. Use "mode dpll" for clock source (see below).
+
+This is based on information provided by Mike Bilow (and verified
+by Paul Helay)
+
+The utility "gencfg"
+--------------------
+
+If you only know the parameters for the PE1CHL driver for DOS,
+run gencfg. It will generate the correct port addresses (I hope).
+Its parameters are exactly the same as the ones you use with
+the "attach scc" command in net, except that the string "init" must
+not appear. Example::
+
+	gencfg 2 0x150 4 2 0 1 0x168 9 4915200
+
+will print a skeleton z8530drv.conf for the OptoSCC to stdout.
+
+::
+
+	gencfg 2 0x300 2 4 5 -4 0 7 4915200 0x10
+
+does the same for the BAYCOM USCC card. In my opinion it is much easier
+to edit scc_config.h...
+
+
+1.2.2 channel configuration
+===========================
+
+The channel definition is divided into three sub sections for each
+channel:
+
+An example for scc0::
+
+	# DEVICE
+
+	device scc0	# the device for the following params
+
+	# MODEM / BUFFERS
+
+	speed 1200		# the default baudrate
+	clock dpll		# clock source:
+				# 	dpll     = normal half duplex operation
+				# 	external = MODEM provides own Rx/Tx clock
+				#	divider  = use full duplex divider if
+				#		   installed (1)
+	mode nrzi		# HDLC encoding mode
+				#	nrzi = 1k2 MODEM, G3RUH 9k6 MODEM
+				#	nrz  = DF9IC 9k6 MODEM
+				#
+	bufsize	384		# size of buffers. Note that this must include
+				# the AX.25 header, not only the data field!
+				# (optional, defaults to 384)
+
+	# KISS (Layer 1)
+
+	txdelay 36              # (see chapter 1.4)
+	persist 64
+	slot    8
+	tail    8
+	fulldup 0
+	wait    12
+	min     3
+	maxkey  7
+	idle    3
+	maxdef  120
+	group   0
+	txoff   off
+	softdcd on
+	slip    off
+
+The order WITHIN these sections is unimportant. The order OF these
+sections IS important. The MODEM parameters are set with the first
+recognized KISS parameter...
+
+Please note that you can initialize the board only once after boot
+(or insmod). You can change all parameters but "mode" and "clock"
+later with the Sccparam program or through KISS. Just to avoid
+security holes...
+
+(1) this divider is usually mounted on the SCC-PBC (PA0HZP) or not
+    present at all (BayCom). It feeds back the output of the DPLL
+    (digital pll) as transmit clock. Using this mode without a divider
+    installed will normally result in keying the transceiver until
+    maxkey expires --- of course without sending anything (useful).
+
+2. Attachment of a channel by your AX.25 software
+=================================================
+
+2.1 Kernel AX.25
+================
+
+To set up an AX.25 device you can simply type::
+
+	ifconfig scc0 44.128.1.1 hw ax25 dl0tha-7
+
+This will create a network interface with the IP number 44.128.20.107
+and the callsign "dl0tha". If you do not have any IP number (yet) you
+can use any of the 44.128.0.0 network. Note that you do not need
+axattach. The purpose of axattach (like slattach) is to create a KISS
+network device linked to a TTY. Please read the documentation of the
+ax25-utils and the AX.25-HOWTO to learn how to set the parameters of
+the kernel AX.25.
+
+2.2 NOS, NET and TFKISS
+=======================
+
+Since the TTY driver (aka KISS TNC emulation) is gone you need
+to emulate the old behaviour. The cost of using these programs is
+that you probably need to compile the kernel AX.25, regardless of whether
+you actually use it or not. First setup your /etc/ax25/axports,
+for example::
+
+	9k6	dl0tha-9  9600  255 4 9600 baud port (scc3)
+	axlink	dl0tha-15 38400 255 4 Link to NOS
+
+Now "ifconfig" the scc device::
+
+	ifconfig scc3 44.128.1.1 hw ax25 dl0tha-9
+
+You can now axattach a pseudo-TTY::
+
+	axattach /dev/ptys0 axlink
+
+and start your NOS and attach /dev/ptys0 there. The problem is that
+NOS is reachable only via digipeating through the kernel AX.25
+(disastrous on a DAMA controlled channel). To solve this problem,
+configure "rxecho" to echo the incoming frames from "9k6" to "axlink"
+and outgoing frames from "axlink" to "9k6" and start::
+
+	rxecho
+
+Or simply use "kissbridge" coming with z8530drv-utils::
+
+	ifconfig scc3 hw ax25 dl0tha-9
+	kissbridge scc3 /dev/ptys0
+
+
+3. Adjustment and Display of parameters
+=======================================
+
+3.1 Displaying SCC Parameters:
+==============================
+
+Once a SCC channel has been attached, the parameter settings and
+some statistic information can be shown using the param program::
+
+	dl1bke-u:~$ sccstat scc0
+
+	Parameters:
+
+	speed       : 1200 baud
+	txdelay     : 36
+	persist     : 255
+	slottime    : 0
+	txtail      : 8
+	fulldup     : 1
+	waittime    : 12
+	mintime     : 3 sec
+	maxkeyup    : 7 sec
+	idletime    : 3 sec
+	maxdefer    : 120 sec
+	group       : 0x00
+	txoff       : off
+	softdcd     : on
+	SLIP        : off
+
+	Status:
+
+	HDLC                  Z8530           Interrupts         Buffers
+	-----------------------------------------------------------------------
+	Sent       :     273  RxOver :     0  RxInts :   125074  Size    :  384
+	Received   :    1095  TxUnder:     0  TxInts :     4684  NoSpace :    0
+	RxErrors   :    1591                  ExInts :    11776
+	TxErrors   :       0                  SpInts :     1503
+	Tx State   :    idle
+
+
+The status info shown is:
+
+==============	==============================================================
+Sent		number of frames transmitted
+Received	number of frames received
+RxErrors	number of receive errors (CRC, ABORT)
+TxErrors	number of discarded Tx frames (due to various reasons)
+Tx State	status of the Tx interrupt handler: idle/busy/active/tail (2)
+RxOver		number of receiver overruns
+TxUnder		number of transmitter underruns
+RxInts		number of receiver interrupts
+TxInts		number of transmitter interrupts
+EpInts		number of receiver special condition interrupts
+SpInts		number of external/status interrupts
+Size		maximum size of an AX.25 frame (*with* AX.25 headers!)
+NoSpace		number of times a buffer could not get allocated
+==============	==============================================================
+
+An overrun is abnormal. If lots of these occur, the product of
+baudrate and number of interfaces is too high for the processing
+power of your computer. NoSpace errors are unlikely to be caused by the
+driver or the kernel AX.25.
+
+
+3.2 Setting Parameters
+======================
+
+
+The setting of parameters of the emulated KISS TNC is done in the
+same way in the SCC driver. You can change parameters by using
+the kissparms program from the ax25-utils package or use the program
+"sccparam"::
+
+     sccparam <device> <paramname> <decimal-|hexadecimal value>
+
+You can change the following parameters:
+
+===========   =====
+param	      value
+===========   =====
+speed         1200
+txdelay       36
+persist       255
+slottime      0
+txtail        8
+fulldup       1
+waittime      12
+mintime       3
+maxkeyup      7
+idletime      3
+maxdefer      120
+group         0x00
+txoff         off
+softdcd       on
+SLIP          off
+===========   =====
+
+
+The parameters have the following meaning:
+
+speed:
+     The baudrate on this channel in bits/sec
+
+     Example: sccparam /dev/scc3 speed 9600
+
+txdelay:
+     The delay (in units of 10 ms) after keying of the
+     transmitter, until the first byte is sent. This is usually
+     called "TXDELAY" in a TNC.  When 0 is specified, the driver
+     will just wait until the CTS signal is asserted. This
+     assumes the presence of a timer or other circuitry in the
+     MODEM and/or transmitter, that asserts CTS when the
+     transmitter is ready for data.
+     A normal value of this parameter is 30-36.
+
+     Example: sccparam /dev/scc0 txd 20
+
+persist:
+     This is the probability that the transmitter will be keyed
+     when the channel is found to be free.  It is a value from 0
+     to 255, and the probability is (value+1)/256.  The value
+     should be somewhere near 50-60, and should be lowered when
+     the channel is used more heavily.
+
+     Example: sccparam /dev/scc2 persist 20
+
+slottime:
+     This is the time between samples of the channel. It is
+     expressed in units of 10 ms.  About 200-300 ms (value 20-30)
+     seems to be a good value.
+
+     Example: sccparam /dev/scc0 slot 20
+
+tail:
+     The time the transmitter will remain keyed after the last
+     byte of a packet has been transferred to the SCC. This is
+     necessary because the CRC and a flag still have to leave the
+     SCC before the transmitter is keyed down. The value depends
+     on the baudrate selected.  A few character times should be
+     sufficient, e.g. 40ms at 1200 baud. (value 4)
+     The value of this parameter is in 10 ms units.
+
+     Example: sccparam /dev/scc2 4
+
+full:
+     The full-duplex mode switch. This can be one of the following
+     values:
+
+     0:   The interface will operate in CSMA mode (the normal
+	  half-duplex packet radio operation)
+     1:   Fullduplex mode, i.e. the transmitter will be keyed at
+	  any time, without checking the received carrier.  It
+	  will be unkeyed when there are no packets to be sent.
+     2:   Like 1, but the transmitter will remain keyed, also
+	  when there are no packets to be sent.  Flags will be
+	  sent in that case, until a timeout (parameter 10)
+	  occurs.
+
+     Example: sccparam /dev/scc0 fulldup off
+
+wait:
+     The initial waittime before any transmit attempt, after the
+     frame has been queue for transmit.  This is the length of
+     the first slot in CSMA mode.  In full duplex modes it is
+     set to 0 for maximum performance.
+     The value of this parameter is in 10 ms units.
+
+     Example: sccparam /dev/scc1 wait 4
+
+maxkey:
+     The maximal time the transmitter will be keyed to send
+     packets, in seconds.  This can be useful on busy CSMA
+     channels, to avoid "getting a bad reputation" when you are
+     generating a lot of traffic.  After the specified time has
+     elapsed, no new frame will be started. Instead, the trans-
+     mitter will be switched off for a specified time (parameter
+     min), and then the selected algorithm for keyup will be
+     started again.
+     The value 0 as well as "off" will disable this feature,
+     and allow infinite transmission time.
+
+     Example: sccparam /dev/scc0 maxk 20
+
+min:
+     This is the time the transmitter will be switched off when
+     the maximum transmission time is exceeded.
+
+     Example: sccparam /dev/scc3 min 10
+
+idle:
+     This parameter specifies the maximum idle time in full duplex
+     2 mode, in seconds.  When no frames have been sent for this
+     time, the transmitter will be keyed down.  A value of 0 is
+     has same result as the fullduplex mode 1. This parameter
+     can be disabled.
+
+     Example: sccparam /dev/scc2 idle off	# transmit forever
+
+maxdefer
+     This is the maximum time (in seconds) to wait for a free channel
+     to send. When this timer expires the transmitter will be keyed
+     IMMEDIATELY. If you love to get trouble with other users you
+     should set this to a very low value ;-)
+
+     Example: sccparam /dev/scc0 maxdefer 240	# 2 minutes
+
+
+txoff:
+     When this parameter has the value 0, the transmission of packets
+     is enable. Otherwise it is disabled.
+
+     Example: sccparam /dev/scc2 txoff on
+
+group:
+     It is possible to build special radio equipment to use more than
+     one frequency on the same band, e.g. using several receivers and
+     only one transmitter that can be switched between frequencies.
+     Also, you can connect several radios that are active on the same
+     band.  In these cases, it is not possible, or not a good idea, to
+     transmit on more than one frequency.  The SCC driver provides a
+     method to lock transmitters on different interfaces, using the
+     "param <interface> group <x>" command.  This will only work when
+     you are using CSMA mode (parameter full = 0).
+
+     The number <x> must be 0 if you want no group restrictions, and
+     can be computed as follows to create restricted groups:
+     <x> is the sum of some OCTAL numbers:
+
+
+     ===  =======================================================
+     200  This transmitter will only be keyed when all other
+	  transmitters in the group are off.
+     100  This transmitter will only be keyed when the carrier
+	  detect of all other interfaces in the group is off.
+     0xx  A byte that can be used to define different groups.
+	  Interfaces are in the same group, when the logical AND
+	  between their xx values is nonzero.
+     ===  =======================================================
+
+     Examples:
+
+     When 2 interfaces use group 201, their transmitters will never be
+     keyed at the same time.
+
+     When 2 interfaces use group 101, the transmitters will only key
+     when both channels are clear at the same time.  When group 301,
+     the transmitters will not be keyed at the same time.
+
+     Don't forget to convert the octal numbers into decimal before
+     you set the parameter.
+
+     Example: (to be written)
+
+softdcd:
+     use a software dcd instead of the real one... Useful for a very
+     slow squelch.
+
+     Example: sccparam /dev/scc0 soft on
+
+
+4. Problems
+===========
+
+If you have tx-problems with your BayCom USCC card please check

+Z8530 Programming Guide
+=======================
+
+:Author: Alan Cox
+
+Introduction
+============
+
+The Z85x30 family synchronous/asynchronous controller chips are used on
+a large number of cheap network interface cards. The kernel provides a
+core interface layer that is designed to make it easy to provide WAN
+services using this chip.
+
+The current driver only support synchronous operation. Merging the
+asynchronous driver support into this code to allow any Z85x30 device to
+be used as both a tty interface and as a synchronous controller is a
+project for Linux post the 2.4 release
+
+Driver Modes
+============
+
+The Z85230 driver layer can drive Z8530, Z85C30 and Z85230 devices in
+three different modes. Each mode can be applied to an individual channel
+on the chip (each chip has two channels).
+
+The PIO synchronous mode supports the most common Z8530 wiring. Here the
+chip is interface to the I/O and interrupt facilities of the host
+machine but not to the DMA subsystem. When running PIO the Z8530 has
+extremely tight timing requirements. Doing high speeds, even with a
+Z85230 will be tricky. Typically you should expect to achieve at best
+9600 baud with a Z8C530 and 64Kbits with a Z85230.
+
+The DMA mode supports the chip when it is configured to use dual DMA
+channels on an ISA bus. The better cards tend to support this mode of
+operation for a single channel. With DMA running the Z85230 tops out
+when it starts to hit ISA DMA constraints at about 512Kbits. It is worth
+noting here that many PC machines hang or crash when the chip is driven
+fast enough to hold the ISA bus solid.
+
+Transmit DMA mode uses a single DMA channel. The DMA channel is used for
+transmission as the transmit FIFO is smaller than the receive FIFO. it
+gives better performance than pure PIO mode but is nowhere near as ideal
+as pure DMA mode.
+
+Using the Z85230 driver
+=======================
+
+The Z85230 driver provides the back end interface to your board. To
+configure a Z8530 interface you need to detect the board and to identify
+its ports and interrupt resources. It is also your problem to verify the
+resources are available.
+
+Having identified the chip you need to fill in a struct z8530_dev,
+which describes each chip. This object must exist until you finally
+shutdown the board. Firstly zero the active field. This ensures nothing
+goes off without you intending it. The irq field should be set to the
+interrupt number of the chip. (Each chip has a single interrupt source
+rather than each channel). You are responsible for allocating the
+interrupt line. The interrupt handler should be set to
+:c:func:`z8530_interrupt()`. The device id should be set to the
+z8530_dev structure pointer. Whether the interrupt can be shared or not
+is board dependent, and up to you to initialise.
+
+The structure holds two channel structures. Initialise chanA.ctrlio and
+chanA.dataio with the address of the control and data ports. You can or
+this with Z8530_PORT_SLEEP to indicate your interface needs the 5uS
+delay for chip settling done in software. The PORT_SLEEP option is
+architecture specific. Other flags may become available on future
+platforms, eg for MMIO. Initialise the chanA.irqs to &z8530_nop to
+start the chip up as disabled and discarding interrupt events. This
+ensures that stray interrupts will be mopped up and not hang the bus.
+Set chanA.dev to point to the device structure itself. The private and
+name field you may use as you wish. The private field is unused by the
+Z85230 layer. The name is used for error reporting and it may thus make
+sense to make it match the network name.
+
+Repeat the same operation with the B channel if your chip has both
+channels wired to something useful. This isn't always the case. If it is
+not wired then the I/O values do not matter, but you must initialise
+chanB.dev.
+
+If your board has DMA facilities then initialise the txdma and rxdma
+fields for the relevant channels. You must also allocate the ISA DMA
+channels and do any necessary board level initialisation to configure
+them. The low level driver will do the Z8530 and DMA controller
+programming but not board specific magic.
+
+Having initialised the device you can then call
+:c:func:`z8530_init()`. This will probe the chip and reset it into
+a known state. An identification sequence is then run to identify the
+chip type. If the checks fail to pass the function returns a non zero
+error code. Typically this indicates that the port given is not valid.
+After this call the type field of the z8530_dev structure is
+initialised to either Z8530, Z85C30 or Z85230 according to the chip
+found.
+
+Once you have called z8530_init you can also make use of the utility
+function :c:func:`z8530_describe()`. This provides a consistent
+reporting format for the Z8530 devices, and allows all the drivers to
+provide consistent reporting.
+
+Attaching Network Interfaces
+============================
+
+If you wish to use the network interface facilities of the driver, then
+you need to attach a network device to each channel that is present and
+in use. In addition to use the generic HDLC you need to follow some
+additional plumbing rules. They may seem complex but a look at the
+example hostess_sv11 driver should reassure you.
+
+The network device used for each channel should be pointed to by the
+netdevice field of each channel. The hdlc-> priv field of the network
+device points to your private data - you will need to be able to find
+your private data from this.
+
+The way most drivers approach this particular problem is to create a
+structure holding the Z8530 device definition and put that into the
+private field of the network device. The network device fields of the
+channels then point back to the network devices.
+
+If you wish to use the generic HDLC then you need to register the HDLC
+device.
+
+Before you register your network device you will also need to provide
+suitable handlers for most of the network device callbacks. See the
+network device documentation for more details on this.
+
+Configuring And Activating The Port
+===================================
+
+The Z85230 driver provides helper functions and tables to load the port
+registers on the Z8530 chips. When programming the register settings for
+a channel be aware that the documentation recommends initialisation
+orders. Strange things happen when these are not followed.
+
+:c:func:`z8530_channel_load()` takes an array of pairs of
+initialisation values in an array of u8 type. The first value is the
+Z8530 register number. Add 16 to indicate the alternate register bank on
+the later chips. The array is terminated by a 255.
+
+The driver provides a pair of public tables. The z8530_hdlc_kilostream
+table is for the UK 'Kilostream' service and also happens to cover most
+other end host configurations. The z8530_hdlc_kilostream_85230 table
+is the same configuration using the enhancements of the 85230 chip. The
+configuration loaded is standard NRZ encoded synchronous data with HDLC
+bitstuffing. All of the timing is taken from the other end of the link.
+
+When writing your own tables be aware that the driver internally tracks
+register values. It may need to reload values. You should therefore be
+sure to set registers 1-7, 9-11, 14 and 15 in all configurations. Where
+the register settings depend on DMA selection the driver will update the
+bits itself when you open or close. Loading a new table with the
+interface open is not recommended.
+
+There are three standard configurations supported by the core code. In
+PIO mode the interface is programmed up to use interrupt driven PIO.
+This places high demands on the host processor to avoid latency. The
+driver is written to take account of latency issues but it cannot avoid
+latencies caused by other drivers, notably IDE in PIO mode. Because the
+drivers allocate buffers you must also prevent MTU changes while the
+port is open.
+
+Once the port is open it will call the rx_function of each channel
+whenever a completed packet arrived. This is invoked from interrupt
+context and passes you the channel and a network buffer (struct
+sk_buff) holding the data. The data includes the CRC bytes so most
+users will want to trim the last two bytes before processing the data.
+This function is very timing critical. When you wish to simply discard
+data the support code provides the function
+:c:func:`z8530_null_rx()` to discard the data.
+
+To active PIO mode sending and receiving the ``z8530_sync_open`` is called.
+This expects to be passed the network device and the channel. Typically
+this is called from your network device open callback. On a failure a
+non zero error status is returned.
+The :c:func:`z8530_sync_close()` function shuts down a PIO
+channel. This must be done before the channel is opened again and before
+the driver shuts down and unloads.
+
+The ideal mode of operation is dual channel DMA mode. Here the kernel
+driver will configure the board for DMA in both directions. The driver
+also handles ISA DMA issues such as controller programming and the
+memory range limit for you. This mode is activated by calling the
+:c:func:`z8530_sync_dma_open()` function. On failure a non zero
+error value is returned. Once this mode is activated it can be shut down
+by calling the :c:func:`z8530_sync_dma_close()`. You must call
+the close function matching the open mode you used.
+
+The final supported mode uses a single DMA channel to drive the transmit
+side. As the Z85C30 has a larger FIFO on the receive channel this tends
+to increase the maximum speed a little. This is activated by calling the
+``z8530_sync_txdma_open``. This returns a non zero error code on failure. The
+:c:func:`z8530_sync_txdma_close()` function closes down the Z8530
+interface from this mode.
+
+Network Layer Functions
+=======================
+
+The Z8530 layer provides functions to queue packets for transmission.
+The driver internally buffers the frame currently being transmitted and
+one further frame (in order to keep back to back transmission running).
+Any further buffering is up to the caller.
+
+The function :c:func:`z8530_queue_xmit()` takes a network buffer
+in sk_buff format and queues it for transmission. The caller must
+provide the entire packet with the exception of the bitstuffing and CRC.
+This is normally done by the caller via the generic HDLC interface
+layer. It returns 0 if the buffer has been queued and non zero values
+for queue full. If the function accepts the buffer it becomes property
+of the Z8530 layer and the caller should not free it.
+
+The function :c:func:`z8530_get_stats()` returns a pointer to an
+internally maintained per interface statistics block. This provides most
+of the interface code needed to implement the network layer get_stats
+callback.
+
+Porting The Z8530 Driver
+========================
+
+The Z8530 driver is written to be portable. In DMA mode it makes
+assumptions about the use of ISA DMA. These are probably warranted in
+most cases as the Z85230 in particular was designed to glue to PC type
+machines. The PIO mode makes no real assumptions.
+
+Should you need to retarget the Z8530 driver to another architecture the
+only code that should need changing are the port I/O functions. At the
+moment these assume PC I/O port accesses. This may not be appropriate
+for all platforms. Replacing :c:func:`z8530_read_port()` and
+``z8530_write_port`` is intended to be all that is required to port
+this driver layer.
+
+Known Bugs And Assumptions
+==========================
+
+Interrupt Locking
+    The locking in the driver is done via the global cli/sti lock. This
+    makes for relatively poor SMP performance. Switching this to use a
+    per device spin lock would probably materially improve performance.
+
+Occasional Failures
+    We have reports of occasional failures when run for very long
+    periods of time and the driver starts to receive junk frames. At the
+    moment the cause of this is not clear.

-only code that should need changing are the port I/O functions. At the
-moment these assume PC I/O port accesses. This may not be appropriate
-for all platforms. Replacing :c:func:`z8530_read_port()` and
-``z8530_write_port`` is intended to be all that is required to port
-this driver layer.
-
-Known Bugs And Assumptions
-==========================
-
-Interrupt Locking
-    The locking in the driver is done via the global cli/sti lock. This
-    makes for relatively poor SMP performance. Switching this to use a
-    per device spin lock would probably materially improve performance.
-
-Occasional Failures
-    We have reports of occasional failures when run for very long
-    periods of time and the driver starts to receive junk frames. At the
-    moment the cause of this is not clear.

-SCC.C - Linux driver for Z8530 based HDLC cards for AX.25
-=========================================================

-This is a subset of the documentation. To use this driver you MUST have the
-full package from:
-
-Internet:
-
-    1. ftp://ftp.ccac.rwth-aachen.de/pub/jr/z8530drv-utils_3.0-3.tar.gz

-1. Initialization of the driver
-===============================
-
-To use the driver, 3 steps must be performed:
-
-     1. if compiled as module: loading the module
-     2. Setup of hardware, MODEM and KISS parameters with sccinit
-     3. Attach each channel to the Linux kernel AX.25 with "ifconfig"
-
-Unlike the versions below 2.4 this driver is a real network device
-driver. If you want to run xNOS instead of our fine kernel AX.25
-use a 2.x version (available from above sites) or read the
-AX.25-HOWTO on how to emulate a KISS TNC on network device drivers.
-
-
-1.1 Loading the module
-======================
-
-(If you're going to compile the driver as a part of the kernel image,
- skip this chapter and continue with 1.2)
-
-Before you can use a module, you'll have to load it with::
-
-	insmod scc.o
-
-please read 'man insmod' that comes with module-init-tools.
-
-You should include the insmod in one of the /etc/rc.d/rc.* files,
-and don't forget to insert a call of sccinit after that. It
-will read your /etc/z8530drv.conf.
-
-1.2. /etc/z8530drv.conf
-=======================
-
-To setup all parameters you must run /sbin/sccinit from one
-of your rc.*-files. This has to be done BEFORE you can
-"ifconfig" an interface. Sccinit reads the file /etc/z8530drv.conf
-and sets the hardware, MODEM and KISS parameters. A sample file is
-delivered with this package. Change it to your needs.
-
-The file itself consists of two main sections.
-
-1.2.1 configuration of hardware parameters
-==========================================
-
-The hardware setup section defines the following parameters for each
-Z8530::
-
-    chip    1
-    data_a  0x300                   # data port A
-    ctrl_a  0x304                   # control port A
-    data_b  0x301                   # data port B
-    ctrl_b  0x305                   # control port B
-    irq     5                       # IRQ No. 5
-    pclock  4915200                 # clock
-    board   BAYCOM                  # hardware type
-    escc    no                      # enhanced SCC chip? (8580/85180/85280)
-    vector  0                       # latch for interrupt vector
-    special no                      # address of special function register
-    option  0                       # option to set via sfr
-
-
-chip
-	- this is just a delimiter to make sccinit a bit simpler to
-	  program. A parameter has no effect.
-
-data_a
-	- the address of the data port A of this Z8530 (needed)
-ctrl_a
-	- the address of the control port A (needed)
-data_b
-	- the address of the data port B (needed)
-ctrl_b
-	- the address of the control port B (needed)
-
-irq
-	- the used IRQ for this chip. Different chips can use different
-	  IRQs or the same. If they share an interrupt, it needs to be
-	  specified within one chip-definition only.
-
-pclock  - the clock at the PCLK pin of the Z8530 (option, 4915200 is
-	  default), measured in Hertz
-
-board
-	- the "type" of the board:
-
-	   =======================  ========
-	   SCC type                 value
-	   =======================  ========
-	   PA0HZP SCC card          PA0HZP
-	   EAGLE card               EAGLE
-	   PC100 card               PC100
-	   PRIMUS-PC (DG9BL) card   PRIMUS
-	   BayCom (U)SCC card       BAYCOM
-	   =======================  ========
-
-escc
-	- if you want support for ESCC chips (8580, 85180, 85280), set
-	  this to "yes" (option, defaults to "no")
-
-vector
-	- address of the vector latch (aka "intack port") for PA0HZP
-	  cards. There can be only one vector latch for all chips!
-	  (option, defaults to 0)
-
-special
-	- address of the special function register on several cards.
-	  (option, defaults to 0)
-
-option  - The value you write into that register (option, default is 0)
-
-You can specify up to four chips (8 channels). If this is not enough,
-just change::
-
-	#define MAXSCC 4
-
-to a higher value.
-
-Example for the BAYCOM USCC:
-----------------------------
-
-::
-
-	chip    1
-	data_a  0x300                   # data port A
-	ctrl_a  0x304                   # control port A
-	data_b  0x301                   # data port B
-	ctrl_b  0x305                   # control port B
-	irq     5                       # IRQ No. 5 (#)
-	board   BAYCOM                  # hardware type (*)
-	#
-	# SCC chip 2
-	#
-	chip    2
-	data_a  0x302
-	ctrl_a  0x306
-	data_b  0x303
-	ctrl_b  0x307
-	board   BAYCOM
-
-An example for a PA0HZP card:
------------------------------
-
-::
-
-	chip 1
-	data_a 0x153
-	data_b 0x151
-	ctrl_a 0x152
-	ctrl_b 0x150
-	irq 9
-	pclock 4915200
-	board PA0HZP
-	vector 0x168
-	escc no
-	#
-	#
-	#
-	chip 2
-	data_a 0x157
-	data_b 0x155
-	ctrl_a 0x156
-	ctrl_b 0x154
-	irq 9
-	pclock 4915200
-	board PA0HZP
-	vector 0x168
-	escc no
-
-A DRSI would should probably work with this:
---------------------------------------------
-(actually: two DRSI cards...)
-
-::
-
-	chip 1
-	data_a 0x303
-	data_b 0x301
-	ctrl_a 0x302
-	ctrl_b 0x300
-	irq 7
-	pclock 4915200
-	board DRSI
-	escc no
-	#
-	#
-	#
-	chip 2
-	data_a 0x313
-	data_b 0x311
-	ctrl_a 0x312
-	ctrl_b 0x310
-	irq 7
-	pclock 4915200
-	board DRSI
-	escc no
-
-Note that you cannot use the on-board baudrate generator off DRSI
-cards. Use "mode dpll" for clock source (see below).
-
-This is based on information provided by Mike Bilow (and verified
-by Paul Helay)
-
-The utility "gencfg"
---------------------
-
-If you only know the parameters for the PE1CHL driver for DOS,
-run gencfg. It will generate the correct port addresses (I hope).
-Its parameters are exactly the same as the ones you use with
-the "attach scc" command in net, except that the string "init" must
-not appear. Example::
-
-	gencfg 2 0x150 4 2 0 1 0x168 9 4915200
-
-will print a skeleton z8530drv.conf for the OptoSCC to stdout.
-
-::
-
-	gencfg 2 0x300 2 4 5 -4 0 7 4915200 0x10
-
-does the same for the BAYCOM USCC card. In my opinion it is much easier
-to edit scc_config.h...
-
-
-1.2.2 channel configuration
-===========================
-
-The channel definition is divided into three sub sections for each
-channel:
-
-An example for scc0::
-
-	# DEVICE
-
-	device scc0	# the device for the following params
-
-	# MODEM / BUFFERS
-
-	speed 1200		# the default baudrate
-	clock dpll		# clock source:
-				# 	dpll     = normal half duplex operation
-				# 	external = MODEM provides own Rx/Tx clock
-				#	divider  = use full duplex divider if
-				#		   installed (1)
-	mode nrzi		# HDLC encoding mode
-				#	nrzi = 1k2 MODEM, G3RUH 9k6 MODEM
-				#	nrz  = DF9IC 9k6 MODEM
-				#
-	bufsize	384		# size of buffers. Note that this must include
-				# the AX.25 header, not only the data field!
-				# (optional, defaults to 384)
-
-	# KISS (Layer 1)
-
-	txdelay 36              # (see chapter 1.4)
-	persist 64
-	slot    8
-	tail    8
-	fulldup 0
-	wait    12
-	min     3
-	maxkey  7
-	idle    3
-	maxdef  120
-	group   0
-	txoff   off
-	softdcd on
-	slip    off
-
-The order WITHIN these sections is unimportant. The order OF these
-sections IS important. The MODEM parameters are set with the first
-recognized KISS parameter...
-
-Please note that you can initialize the board only once after boot
-(or insmod). You can change all parameters but "mode" and "clock"
-later with the Sccparam program or through KISS. Just to avoid
-security holes...
-
-(1) this divider is usually mounted on the SCC-PBC (PA0HZP) or not
-    present at all (BayCom). It feeds back the output of the DPLL
-    (digital pll) as transmit clock. Using this mode without a divider
-    installed will normally result in keying the transceiver until
-    maxkey expires --- of course without sending anything (useful).
-
-2. Attachment of a channel by your AX.25 software
-=================================================
-
-2.1 Kernel AX.25
-================
-
-To set up an AX.25 device you can simply type::
-
-	ifconfig scc0 44.128.1.1 hw ax25 dl0tha-7
-
-This will create a network interface with the IP number 44.128.20.107
-and the callsign "dl0tha". If you do not have any IP number (yet) you
-can use any of the 44.128.0.0 network. Note that you do not need
-axattach. The purpose of axattach (like slattach) is to create a KISS
-network device linked to a TTY. Please read the documentation of the
-ax25-utils and the AX.25-HOWTO to learn how to set the parameters of
-the kernel AX.25.
-
-2.2 NOS, NET and TFKISS
-=======================
-
-Since the TTY driver (aka KISS TNC emulation) is gone you need
-to emulate the old behaviour. The cost of using these programs is
-that you probably need to compile the kernel AX.25, regardless of whether
-you actually use it or not. First setup your /etc/ax25/axports,
-for example::
-
-	9k6	dl0tha-9  9600  255 4 9600 baud port (scc3)
-	axlink	dl0tha-15 38400 255 4 Link to NOS
-
-Now "ifconfig" the scc device::
-
-	ifconfig scc3 44.128.1.1 hw ax25 dl0tha-9
-
-You can now axattach a pseudo-TTY::
-
-	axattach /dev/ptys0 axlink
-
-and start your NOS and attach /dev/ptys0 there. The problem is that
-NOS is reachable only via digipeating through the kernel AX.25
-(disastrous on a DAMA controlled channel). To solve this problem,
-configure "rxecho" to echo the incoming frames from "9k6" to "axlink"
-and outgoing frames from "axlink" to "9k6" and start::
-
-	rxecho
-
-Or simply use "kissbridge" coming with z8530drv-utils::
-
-	ifconfig scc3 hw ax25 dl0tha-9
-	kissbridge scc3 /dev/ptys0
-
-
-3. Adjustment and Display of parameters
-=======================================
-
-3.1 Displaying SCC Parameters:
-==============================
-
-Once a SCC channel has been attached, the parameter settings and
-some statistic information can be shown using the param program::
-
-	dl1bke-u:~$ sccstat scc0
-
-	Parameters:
-
-	speed       : 1200 baud
-	txdelay     : 36
-	persist     : 255
-	slottime    : 0
-	txtail      : 8
-	fulldup     : 1
-	waittime    : 12
-	mintime     : 3 sec
-	maxkeyup    : 7 sec
-	idletime    : 3 sec
-	maxdefer    : 120 sec
-	group       : 0x00
-	txoff       : off
-	softdcd     : on
-	SLIP        : off
-
-	Status:
-
-	HDLC                  Z8530           Interrupts         Buffers
-	-----------------------------------------------------------------------
-	Sent       :     273  RxOver :     0  RxInts :   125074  Size    :  384
-	Received   :    1095  TxUnder:     0  TxInts :     4684  NoSpace :    0
-	RxErrors   :    1591                  ExInts :    11776
-	TxErrors   :       0                  SpInts :     1503
-	Tx State   :    idle
-
-
-The status info shown is:
-
-==============	==============================================================
-Sent		number of frames transmitted
-Received	number of frames received
-RxErrors	number of receive errors (CRC, ABORT)
-TxErrors	number of discarded Tx frames (due to various reasons)
-Tx State	status of the Tx interrupt handler: idle/busy/active/tail (2)
-RxOver		number of receiver overruns
-TxUnder		number of transmitter underruns
-RxInts		number of receiver interrupts
-TxInts		number of transmitter interrupts
-EpInts		number of receiver special condition interrupts
-SpInts		number of external/status interrupts
-Size		maximum size of an AX.25 frame (*with* AX.25 headers!)
-NoSpace		number of times a buffer could not get allocated
-==============	==============================================================
-
-An overrun is abnormal. If lots of these occur, the product of
-baudrate and number of interfaces is too high for the processing
-power of your computer. NoSpace errors are unlikely to be caused by the
-driver or the kernel AX.25.
-
-
-3.2 Setting Parameters
-======================
-
-
-The setting of parameters of the emulated KISS TNC is done in the
-same way in the SCC driver. You can change parameters by using
-the kissparms program from the ax25-utils package or use the program
-"sccparam"::
-
-     sccparam <device> <paramname> <decimal-|hexadecimal value>
-
-You can change the following parameters:
-
-===========   =====
-param	      value
-===========   =====
-speed         1200
-txdelay       36
-persist       255
-slottime      0
-txtail        8
-fulldup       1
-waittime      12
-mintime       3
-maxkeyup      7
-idletime      3
-maxdefer      120
-group         0x00
-txoff         off
-softdcd       on
-SLIP          off
-===========   =====
-
-
-The parameters have the following meaning:
-
-speed:
-     The baudrate on this channel in bits/sec
-
-     Example: sccparam /dev/scc3 speed 9600
-
-txdelay:
-     The delay (in units of 10 ms) after keying of the
-     transmitter, until the first byte is sent. This is usually
-     called "TXDELAY" in a TNC.  When 0 is specified, the driver
-     will just wait until the CTS signal is asserted. This
-     assumes the presence of a timer or other circuitry in the
-     MODEM and/or transmitter, that asserts CTS when the
-     transmitter is ready for data.
-     A normal value of this parameter is 30-36.
-
-     Example: sccparam /dev/scc0 txd 20
-
-persist:
-     This is the probability that the transmitter will be keyed
-     when the channel is found to be free.  It is a value from 0
-     to 255, and the probability is (value+1)/256.  The value
-     should be somewhere near 50-60, and should be lowered when
-     the channel is used more heavily.
-
-     Example: sccparam /dev/scc2 persist 20
-
-slottime:
-     This is the time between samples of the channel. It is
-     expressed in units of 10 ms.  About 200-300 ms (value 20-30)
-     seems to be a good value.
-
-     Example: sccparam /dev/scc0 slot 20
-
-tail:
-     The time the transmitter will remain keyed after the last
-     byte of a packet has been transferred to the SCC. This is
-     necessary because the CRC and a flag still have to leave the
-     SCC before the transmitter is keyed down. The value depends
-     on the baudrate selected.  A few character times should be
-     sufficient, e.g. 40ms at 1200 baud. (value 4)
-     The value of this parameter is in 10 ms units.
-
-     Example: sccparam /dev/scc2 4
-
-full:
-     The full-duplex mode switch. This can be one of the following
-     values:
-
-     0:   The interface will operate in CSMA mode (the normal
-	  half-duplex packet radio operation)
-     1:   Fullduplex mode, i.e. the transmitter will be keyed at
-	  any time, without checking the received carrier.  It
-	  will be unkeyed when there are no packets to be sent.
-     2:   Like 1, but the transmitter will remain keyed, also
-	  when there are no packets to be sent.  Flags will be
-	  sent in that case, until a timeout (parameter 10)
-	  occurs.
-
-     Example: sccparam /dev/scc0 fulldup off
-
-wait:
-     The initial waittime before any transmit attempt, after the
-     frame has been queue for transmit.  This is the length of
-     the first slot in CSMA mode.  In full duplex modes it is
-     set to 0 for maximum performance.
-     The value of this parameter is in 10 ms units.
-
-     Example: sccparam /dev/scc1 wait 4
-
-maxkey:
-     The maximal time the transmitter will be keyed to send
-     packets, in seconds.  This can be useful on busy CSMA
-     channels, to avoid "getting a bad reputation" when you are
-     generating a lot of traffic.  After the specified time has
-     elapsed, no new frame will be started. Instead, the trans-
-     mitter will be switched off for a specified time (parameter
-     min), and then the selected algorithm for keyup will be
-     started again.
-     The value 0 as well as "off" will disable this feature,
-     and allow infinite transmission time.
-
-     Example: sccparam /dev/scc0 maxk 20
-
-min:
-     This is the time the transmitter will be switched off when
-     the maximum transmission time is exceeded.
-
-     Example: sccparam /dev/scc3 min 10
-
-idle:
-     This parameter specifies the maximum idle time in full duplex
-     2 mode, in seconds.  When no frames have been sent for this
-     time, the transmitter will be keyed down.  A value of 0 is
-     has same result as the fullduplex mode 1. This parameter
-     can be disabled.
-
-     Example: sccparam /dev/scc2 idle off	# transmit forever
-
-maxdefer
-     This is the maximum time (in seconds) to wait for a free channel
-     to send. When this timer expires the transmitter will be keyed
-     IMMEDIATELY. If you love to get trouble with other users you
-     should set this to a very low value ;-)
-
-     Example: sccparam /dev/scc0 maxdefer 240	# 2 minutes
-
-
-txoff:
-     When this parameter has the value 0, the transmission of packets
-     is enable. Otherwise it is disabled.
-
-     Example: sccparam /dev/scc2 txoff on
-
-group:
-     It is possible to build special radio equipment to use more than
-     one frequency on the same band, e.g. using several receivers and
-     only one transmitter that can be switched between frequencies.
-     Also, you can connect several radios that are active on the same
-     band.  In these cases, it is not possible, or not a good idea, to
-     transmit on more than one frequency.  The SCC driver provides a
-     method to lock transmitters on different interfaces, using the
-     "param <interface> group <x>" command.  This will only work when
-     you are using CSMA mode (parameter full = 0).
-
-     The number <x> must be 0 if you want no group restrictions, and
-     can be computed as follows to create restricted groups:
-     <x> is the sum of some OCTAL numbers:
-
-
-     ===  =======================================================
-     200  This transmitter will only be keyed when all other
-	  transmitters in the group are off.
-     100  This transmitter will only be keyed when the carrier
-	  detect of all other interfaces in the group is off.
-     0xx  A byte that can be used to define different groups.
-	  Interfaces are in the same group, when the logical AND
-	  between their xx values is nonzero.
-     ===  =======================================================
-
-     Examples:
-
-     When 2 interfaces use group 201, their transmitters will never be
-     keyed at the same time.
-
-     When 2 interfaces use group 101, the transmitters will only key
-     when both channels are clear at the same time.  When group 301,
-     the transmitters will not be keyed at the same time.
-
-     Don't forget to convert the octal numbers into decimal before
-     you set the parameter.
-
-     Example: (to be written)
-
-softdcd:
-     use a software dcd instead of the real one... Useful for a very
-     slow squelch.

-4. Problems
-===========
-
-If you have tx-problems with your BayCom USCC card please check
-the manufacturer of the 8530. SGS chips have a slightly
-different timing. Try Zilog...  A solution is to write to register 8
-instead to the data port, but this won't work with the ESCC chips.
-*SIGH!*
-
-A very common problem is that the PTT locks until the maxkeyup timer
-expires, although interrupts and clock source are correct. In most
-cases compiling the driver with CONFIG_SCC_DELAY (set with
-make config) solves the problems. For more hints read the (pseudo) FAQ
-and the documentation coming with z8530drv-utils.
-
-I got reports that the driver has problems on some 386-based systems.
-(i.e. Amstrad) Those systems have a bogus AT bus timing which will
-lead to delayed answers on interrupts. You can recognize these
-problems by looking at the output of Sccstat for the suspected
-port. If it shows under- and overruns you own such a system.
-
-Delayed processing of received data: This depends on
-
-- the kernel version
-
-- kernel profiling compiled or not
-
-- a high interrupt load
-
-- a high load of the machine --- running X, Xmorph, XV and Povray,
-  while compiling the kernel... hmm ... even with 32 MB RAM ...  ;-)
-  Or running a named for the whole .ampr.org domain on an 8 MB
-  box...
-
-- using information from rxecho or kissbridge.
-
-Kernel panics: please read /linux/README and find out if it
-really occurred within the scc driver.
-
-If you cannot solve a problem, send me
-
-- a description of the problem,
-- information on your hardware (computer system, scc board, modem)
-- your kernel version
-- the output of cat /proc/net/z8530

-4. Thor RLC100

-Mysteriously this board seems not to work with the driver. Anyone
-got it up-and-running?

-Many thanks to Linus Torvalds and Alan Cox for including the driver
-in the Linux standard distribution and their support.

-Linux Drivers for Baycom Modems
-===============================
-
-Thomas M. Sailer, HB9JNX/AE4WA, <sailer@ife.ee.ethz.ch>
-
-The drivers for the baycom modems have been split into
-separate drivers as they did not share any code, and the driver
-and device names have changed.
-
-This document describes the Linux Kernel Drivers for simple Baycom style
-amateur radio modems.
-
-The following drivers are available:
-====================================
-
-baycom_ser_fdx:
-  This driver supports the SER12 modems either full or half duplex.
-  Its baud rate may be changed via the ``baud`` module parameter,
-  therefore it supports just about every bit bang modem on a
-  serial port. Its devices are called bcsf0 through bcsf3.
-  This is the recommended driver for SER12 type modems,
-  however if you have a broken UART clone that does not have working
-  delta status bits, you may try baycom_ser_hdx.
-
-baycom_ser_hdx:
-  This is an alternative driver for SER12 type modems.
-  It only supports half duplex, and only 1200 baud. Its devices
-  are called bcsh0 through bcsh3. Use this driver only if baycom_ser_fdx
-  does not work with your UART.
-
-baycom_par:
-  This driver supports the par96 and picpar modems.
-  Its devices are called bcp0 through bcp3.
-
-baycom_epp:
-  This driver supports the EPP modem.
-  Its devices are called bce0 through bce3.
-  This driver is work-in-progress.
-
-The following modems are supported:
-
-======= ========================================================================
-ser12   This is a very simple 1200 baud AFSK modem. The modem consists only
-	of a modulator/demodulator chip, usually a TI TCM3105. The computer
-	is responsible for regenerating the receiver bit clock, as well as
-	for handling the HDLC protocol. The modem connects to a serial port,
-	hence the name. Since the serial port is not used as an async serial
-	port, the kernel driver for serial ports cannot be used, and this
-	driver only supports standard serial hardware (8250, 16450, 16550)
-
-par96   This is a modem for 9600 baud FSK compatible to the G3RUH standard.
-	The modem does all the filtering and regenerates the receiver clock.
-	Data is transferred from and to the PC via a shift register.
-	The shift register is filled with 16 bits and an interrupt is signalled.
-	The PC then empties the shift register in a burst. This modem connects
-	to the parallel port, hence the name. The modem leaves the
-	implementation of the HDLC protocol and the scrambler polynomial to
-	the PC.
-
-picpar  This is a redesign of the par96 modem by Henning Rech, DF9IC. The modem
-	is protocol compatible to par96, but uses only three low power ICs
-	and can therefore be fed from the parallel port and does not require
-	an additional power supply. Furthermore, it incorporates a carrier
-	detect circuitry.
-
-EPP     This is a high-speed modem adaptor that connects to an enhanced parallel
-	port.
-
-	Its target audience is users working over a high speed hub (76.8kbit/s).
-
-eppfpga This is a redesign of the EPP adaptor.
-======= ========================================================================
-
-All of the above modems only support half duplex communications. However,
-the driver supports the KISS (see below) fullduplex command. It then simply
-starts to send as soon as there's a packet to transmit and does not care
-about DCD, i.e. it starts to send even if there's someone else on the channel.
-This command is required by some implementations of the DAMA channel
-access protocol.
-
-
-The Interface of the drivers
-============================
-
-Unlike previous drivers, these drivers are no longer character devices,
-but they are now true kernel network interfaces. Installation is therefore
-simple. Once installed, four interfaces named bc{sf,sh,p,e}[0-3] are available.
-sethdlc from the ax25 utilities may be used to set driver states etc.
-Users of userland AX.25 stacks may use the net2kiss utility (also available
-in the ax25 utilities package) to convert packets of a network interface
-to a KISS stream on a pseudo tty. There's also a patch available from
-me for WAMPES which allows attaching a kernel network interface directly.
-
-
-Configuring the driver
-======================
-
-Every time a driver is inserted into the kernel, it has to know which
-modems it should access at which ports. This can be done with the setbaycom
-utility. If you are only using one modem, you can also configure the
-driver from the insmod command line (or by means of an option line in
-``/etc/modprobe.d/*.conf``).
-
-Examples::
-
-  modprobe baycom_ser_fdx mode="ser12*" iobase=0x3f8 irq=4
-  sethdlc -i bcsf0 -p mode "ser12*" io 0x3f8 irq 4
-
-Both lines configure the first port to drive a ser12 modem at the first
-serial port (COM1 under DOS). The * in the mode parameter instructs the driver
-to use the software DCD algorithm (see below)::
-
-  insmod baycom_par mode="picpar" iobase=0x378
-  sethdlc -i bcp0 -p mode "picpar" io 0x378
-
-Both lines configure the first port to drive a picpar modem at the
-first parallel port (LPT1 under DOS). (Note: picpar implies
-hardware DCD, par96 implies software DCD).
-
-The channel access parameters can be set with sethdlc -a or kissparms.
-Note that both utilities interpret the values slightly differently.
-
-
-Hardware DCD versus Software DCD
-================================
-
-To avoid collisions on the air, the driver must know when the channel is
-busy. This is the task of the DCD circuitry/software. The driver may either
-utilise a software DCD algorithm (options=1) or use a DCD signal from
-the hardware (options=0).
-
-======= =================================================================
-ser12   if software DCD is utilised, the radio's squelch should always be
-	open. It is highly recommended to use the software DCD algorithm,
-	as it is much faster than most hardware squelch circuitry. The
-	disadvantage is a slightly higher load on the system.
-
-par96   the software DCD algorithm for this type of modem is rather poor.
-	The modem simply does not provide enough information to implement
-	a reasonable DCD algorithm in software. Therefore, if your radio
-	feeds the DCD input of the PAR96 modem, the use of the hardware
-	DCD circuitry is recommended.
-
-picpar  the picpar modem features a builtin DCD hardware, which is highly
-	recommended.
-======= =================================================================
-
-
-
-Compatibility with the rest of the Linux kernel
-===============================================
-
-The serial driver and the baycom serial drivers compete
-for the same hardware resources. Of course only one driver can access a given
-interface at a time. The serial driver grabs all interfaces it can find at
-startup time. Therefore the baycom drivers subsequently won't be able to
-access a serial port. You might therefore find it necessary to release
-a port owned by the serial driver with 'setserial /dev/ttyS# uart none', where
-# is the number of the interface. The baycom drivers do not reserve any
-ports at startup, unless one is specified on the 'insmod' command line. Another
-method to solve the problem is to compile all drivers as modules and
-leave it to kmod to load the correct driver depending on the application.
-
-The parallel port drivers (baycom_par, baycom_epp) now use the parport subsystem
-to arbitrate the ports between different client drivers.

+Raylink wireless LAN card
+=========================
+
+September 21, 1999
+
+Copyright |copy| 1998  Corey Thomas (corey@world.std.com)
+
+This file is the documentation for the Raylink Wireless LAN card driver for
+Linux.  The Raylink wireless LAN card is a PCMCIA card which provides IEEE
+802.11 compatible wireless network connectivity at 1 and 2 megabits/second.
+See http://www.raytheon.com/micro/raylink/ for more information on the Raylink
+card.  This driver is in early development and does have bugs.  See the known
+bugs and limitations at the end of this document for more information.
+This driver also works with WebGear's Aviator 2.4 and Aviator Pro
+wireless LAN cards.
+
+As of kernel 2.3.18, the ray_cs driver is part of the Linux kernel
+source.  My web page for the development of ray_cs is at
+http://web.ralinktech.com/ralink/Home/Support/Linux.html
+and I can be emailed at corey@world.std.com
+
+The kernel driver is based on ray_cs-1.62.tgz
+
+The driver at my web page is intended to be used as an add on to
+David Hinds pcmcia package.  All the command line parameters are
+available when compiled as a module.  When built into the kernel, only
+the essid= string parameter is available via the kernel command line.
+This will change after the method of sorting out parameters for all
+the PCMCIA drivers is agreed upon.  If you must have a built in driver
+with nondefault parameters, they can be edited in
+/usr/src/linux/drivers/net/pcmcia/ray_cs.c.  Searching for module_param
+will find them all.
+
+Information on card services is available at:
+
+	http://pcmcia-cs.sourceforge.net/
+
+
+Card services user programs are still required for PCMCIA devices.
+pcmcia-cs-3.1.1 or greater is required for the kernel version of
+the driver.
+
+Currently, ray_cs is not part of David Hinds card services package,
+so the following magic is required.
+
+At the end of the /etc/pcmcia/config.opts file, add the line:
+source ./ray_cs.opts
+This will make card services read the ray_cs.opts file
+when starting.  Create the file /etc/pcmcia/ray_cs.opts containing the
+following::
+
+  #### start of /etc/pcmcia/ray_cs.opts ###################
+  # Configuration options for Raylink Wireless LAN PCMCIA card
+  device "ray_cs"
+    class "network" module "misc/ray_cs"
+
+  card "RayLink PC Card WLAN Adapter"
+    manfid 0x01a6, 0x0000
+    bind "ray_cs"
+
+  module "misc/ray_cs" opts ""
+  #### end of /etc/pcmcia/ray_cs.opts #####################
+
+
+To join an existing network with
+different parameters, contact the network administrator for the
+configuration information, and edit /etc/pcmcia/ray_cs.opts.
+Add the parameters below between the empty quotes.
+
+Parameters for ray_cs driver which may be specified in ray_cs.opts:
+
+=============== =============== =============================================
+bc              integer         0 = normal mode (802.11 timing),
+				1 = slow down inter frame timing to allow
+				operation with older breezecom access
+				points.
+
+beacon_period	integer         beacon period in Kilo-microseconds,
+
+				legal values = must be integer multiple
+				of hop dwell
+
+				default = 256
+
+country         integer         1 = USA (default),
+				2 = Europe,
+				3 = Japan,
+				4 = Korea,
+				5 = Spain,
+				6 = France,
+				7 = Israel,
+				8 = Australia
+
+essid		string		ESS ID - network name to join
+
+				string with maximum length of 32 chars
+				default value = "ADHOC_ESSID"
+
+hop_dwell	integer         hop dwell time in Kilo-microseconds
+
+				legal values = 16,32,64,128(default),256
+
+irq_mask	integer         linux standard 16 bit value 1bit/IRQ
+
+				lsb is IRQ 0, bit 1 is IRQ 1 etc.
+				Used to restrict choice of IRQ's to use.
+				Recommended method for controlling
+				interrupts is in /etc/pcmcia/config.opts
+
+net_type	integer		0 (default) = adhoc network,
+				1 = infrastructure
+
+phy_addr	string          string containing new MAC address in
+				hex, must start with x eg
+				x00008f123456
+
+psm		integer         0 = continuously active,
+				1 = power save mode (not useful yet)
+
+pc_debug	integer		(0-5) larger values for more verbose
+				logging.  Replaces ray_debug.
+
+ray_debug	integer		Replaced with pc_debug
+
+ray_mem_speed   integer         defaults to 500
+
+sniffer         integer         0 = not sniffer (default),
+				1 = sniffer which can be used to record all
+				network traffic using tcpdump or similar,
+				but no normal network use is allowed.
+
+translate	integer		0 = no translation (encapsulate frames),
+				1 = translation    (RFC1042/802.1)
+=============== =============== =============================================
+
+More on sniffer mode:
+
+tcpdump does not understand 802.11 headers, so it can't
+interpret the contents, but it can record to a file.  This is only
+useful for debugging 802.11 lowlevel protocols that are not visible to
+linux.  If you want to watch ftp xfers, or do similar things, you
+don't need to use sniffer mode.  Also, some packet types are never
+sent up by the card, so you will never see them (ack, rts, cts, probe
+etc.)  There is a simple program (showcap) included in the ray_cs
+package which parses the 802.11 headers.
+
+Known Problems and missing features
+
+	Does not work with non x86
+
+	Does not work with SMP
+
+	Support for defragmenting frames is not yet debugged, and in
+	fact is known to not work.  I have never encountered a net set
+	up to fragment, but still, it should be fixed.
+
+	The ioctl support is incomplete.  The hardware address cannot be set
+	using ifconfig yet.  If a different hardware address is needed, it may
+	be set using the phy_addr parameter in ray_cs.opts.  This requires
+	a card insertion to take effect.

-Altera Triple-Speed Ethernet MAC driver
-=======================================
-
-Copyright |copy| 2008-2014 Altera Corporation
-
-This is the driver for the Altera Triple-Speed Ethernet (TSE) controllers
-using the SGDMA and MSGDMA soft DMA IP components. The driver uses the
-platform bus to obtain component resources. The designs used to test this
-driver were built for a Cyclone(R) V SOC FPGA board, a Cyclone(R) V FPGA board,
-and tested with ARM and NIOS processor hosts separately. The anticipated use
-cases are simple communications between an embedded system and an external peer
-for status and simple configuration of the embedded system.
-
-For more information visit www.altera.com and www.rocketboards.org. Support
-forums for the driver may be found on www.rocketboards.org, and a design used
-to test this driver may be found there as well. Support is also available from
-the maintainer of this driver, found in MAINTAINERS.
-
-The Triple-Speed Ethernet, SGDMA, and MSGDMA components are all soft IP
-components that can be assembled and built into an FPGA using the Altera
-Quartus toolchain. Quartus 13.1 and 14.0 were used to build the design that
-this driver was tested against. The sopc2dts tool is used to create the
-device tree for the driver, and may be found at rocketboards.org.
-
-The driver probe function examines the device tree and determines if the
-Triple-Speed Ethernet instance is using an SGDMA or MSGDMA component. The
-probe function then installs the appropriate set of DMA routines to
-initialize, setup transmits, receives, and interrupt handling primitives for
-the respective configurations.
-
-The SGDMA component is to be deprecated in the near future (over the next 1-2
-years as of this writing in early 2014) in favor of the MSGDMA component.
-SGDMA support is included for existing designs and reference in case a
-developer wishes to support their own soft DMA logic and driver support. Any
-new designs should not use the SGDMA.
-
-The SGDMA supports only a single transmit or receive operation at a time, and
-therefore will not perform as well compared to the MSGDMA soft IP. Please
-visit www.altera.com for known, documented SGDMA errata.
-
-Scatter-gather DMA is not supported by the SGDMA or MSGDMA at this time.
-Scatter-gather DMA will be added to a future maintenance update to this
-driver.
-
-Jumbo frames are not supported at this time.
-
-The driver limits PHY operations to 10/100Mbps, and has not yet been fully
-tested for 1Gbps. This support will be added in a future maintenance update.
-
-1. Kernel Configuration
-=======================
-
-The kernel configuration option is ALTERA_TSE:
-
- Device Drivers ---> Network device support ---> Ethernet driver support --->
- Altera Triple-Speed Ethernet MAC support (ALTERA_TSE)
-
-2. Driver parameters list
-=========================
-
-	- debug: message level (0: no output, 16: all);
-	- dma_rx_num: Number of descriptors in the RX list (default is 64);
-	- dma_tx_num: Number of descriptors in the TX list (default is 64).
-
-3. Command line options
-=======================
-
-Driver parameters can be also passed in command line by using::
-
-	altera_tse=dma_rx_num:128,dma_tx_num:512
-
-4. Driver information and notes
-===============================
-
-4.1. Transmit process
----------------------
-When the driver's transmit routine is called by the kernel, it sets up a
-transmit descriptor by calling the underlying DMA transmit routine (SGDMA or
-MSGDMA), and initiates a transmit operation. Once the transmit is complete, an
-interrupt is driven by the transmit DMA logic. The driver handles the transmit
-completion in the context of the interrupt handling chain by recycling
-resource required to send and track the requested transmit operation.
-
-4.2. Receive process
---------------------
-The driver will post receive buffers to the receive DMA logic during driver
-initialization. Receive buffers may or may not be queued depending upon the
-underlying DMA logic (MSGDMA is able queue receive buffers, SGDMA is not able
-to queue receive buffers to the SGDMA receive logic). When a packet is
-received, the DMA logic generates an interrupt. The driver handles a receive
-interrupt by obtaining the DMA receive logic status, reaping receive
-completions until no more receive completions are available.
-
-4.3. Interrupt Mitigation
--------------------------
-The driver is able to mitigate the number of its DMA interrupts
-using NAPI for receive operations. Interrupt mitigation is not yet supported
-for transmit operations, but will be added in a future maintenance release.
-
-4.4) Ethtool support
---------------------
-Ethtool is supported. Driver statistics and internal errors can be taken using:
-ethtool -S ethX command. It is possible to dump registers etc.
-
-4.5) PHY Support
-----------------
-The driver is compatible with PAL to work with PHY and GPHY devices.
-
-4.7) List of source files:
---------------------------
- - Kconfig
- - Makefile
- - altera_tse_main.c: main network device driver
- - altera_tse_ethtool.c: ethtool support
- - altera_tse.h: private driver structure and common definitions
- - altera_msgdma.h: MSGDMA implementation function definitions
- - altera_sgdma.h: SGDMA implementation function definitions
- - altera_msgdma.c: MSGDMA implementation
- - altera_sgdma.c: SGDMA implementation
- - altera_sgdmahw.h: SGDMA register and descriptor definitions
- - altera_msgdmahw.h: MSGDMA register and descriptor definitions
- - altera_utils.c: Driver utility functions
- - altera_utils.h: Driver utility function definitions
-
-5. Debug Information
-====================
-
-The driver exports debug information such as internal statistics,
-debug information, MAC and DMA registers etc.
-
-A user may use the ethtool support to get statistics:
-e.g. using: ethtool -S ethX (that shows the statistics counters)
-or sees the MAC registers: e.g. using: ethtool -d ethX
-
-The developer can also use the "debug" module parameter to get
-further debug information.
-
-6. Statistics Support
-=====================
-
-The controller and driver support a mix of IEEE standard defined statistics,
-RFC defined statistics, and driver or Altera defined statistics. The four
-specifications containing the standard definitions for these statistics are
-as follows:
-
- - IEEE 802.3-2012 - IEEE Standard for Ethernet.
- - RFC 2863 found at http://www.rfc-editor.org/rfc/rfc2863.txt.
- - RFC 2819 found at http://www.rfc-editor.org/rfc/rfc2819.txt.
- - Altera Triple Speed Ethernet User Guide, found at http://www.altera.com
-
-The statistics supported by the TSE and the device driver are as follows:
-
-"tx_packets" is equivalent to aFramesTransmittedOK defined in IEEE 802.3-2012,
-Section 5.2.2.1.2. This statistics is the count of frames that are successfully
-transmitted.
-
-"rx_packets" is equivalent to aFramesReceivedOK defined in IEEE 802.3-2012,
-Section 5.2.2.1.5. This statistic is the count of frames that are successfully
-received. This count does not include any error packets such as CRC errors,
-length errors, or alignment errors.
-
-"rx_crc_errors" is equivalent to aFrameCheckSequenceErrors defined in IEEE
-802.3-2012, Section 5.2.2.1.6. This statistic is the count of frames that are
-an integral number of bytes in length and do not pass the CRC test as the frame
-is received.
-

+Altera Triple-Speed Ethernet MAC driver
+=======================================
+
+Copyright |copy| 2008-2014 Altera Corporation
+
+This is the driver for the Altera Triple-Speed Ethernet (TSE) controllers
+using the SGDMA and MSGDMA soft DMA IP components. The driver uses the
+platform bus to obtain component resources. The designs used to test this
+driver were built for a Cyclone(R) V SOC FPGA board, a Cyclone(R) V FPGA board,
+and tested with ARM and NIOS processor hosts separately. The anticipated use
+cases are simple communications between an embedded system and an external peer
+for status and simple configuration of the embedded system.
+
+For more information visit www.altera.com and www.rocketboards.org. Support
+forums for the driver may be found on www.rocketboards.org, and a design used
+to test this driver may be found there as well. Support is also available from
+the maintainer of this driver, found in MAINTAINERS.
+
+The Triple-Speed Ethernet, SGDMA, and MSGDMA components are all soft IP
+components that can be assembled and built into an FPGA using the Altera
+Quartus toolchain. Quartus 13.1 and 14.0 were used to build the design that
+this driver was tested against. The sopc2dts tool is used to create the
+device tree for the driver, and may be found at rocketboards.org.
+
+The driver probe function examines the device tree and determines if the
+Triple-Speed Ethernet instance is using an SGDMA or MSGDMA component. The
+probe function then installs the appropriate set of DMA routines to
+initialize, setup transmits, receives, and interrupt handling primitives for
+the respective configurations.
+
+The SGDMA component is to be deprecated in the near future (over the next 1-2
+years as of this writing in early 2014) in favor of the MSGDMA component.
+SGDMA support is included for existing designs and reference in case a
+developer wishes to support their own soft DMA logic and driver support. Any
+new designs should not use the SGDMA.
+
+The SGDMA supports only a single transmit or receive operation at a time, and
+therefore will not perform as well compared to the MSGDMA soft IP. Please
+visit www.altera.com for known, documented SGDMA errata.
+
+Scatter-gather DMA is not supported by the SGDMA or MSGDMA at this time.
+Scatter-gather DMA will be added to a future maintenance update to this
+driver.
+
+Jumbo frames are not supported at this time.
+
+The driver limits PHY operations to 10/100Mbps, and has not yet been fully
+tested for 1Gbps. This support will be added in a future maintenance update.
+
+1. Kernel Configuration
+=======================
+
+The kernel configuration option is ALTERA_TSE:
+
+ Device Drivers ---> Network device support ---> Ethernet driver support --->
+ Altera Triple-Speed Ethernet MAC support (ALTERA_TSE)
+
+2. Driver parameters list
+=========================
+
+	- debug: message level (0: no output, 16: all);
+	- dma_rx_num: Number of descriptors in the RX list (default is 64);
+	- dma_tx_num: Number of descriptors in the TX list (default is 64).
+
+3. Command line options
+=======================
+
+Driver parameters can be also passed in command line by using::
+
+	altera_tse=dma_rx_num:128,dma_tx_num:512
+
+4. Driver information and notes
+===============================
+
+4.1. Transmit process
+---------------------
+When the driver's transmit routine is called by the kernel, it sets up a
+transmit descriptor by calling the underlying DMA transmit routine (SGDMA or
+MSGDMA), and initiates a transmit operation. Once the transmit is complete, an
+interrupt is driven by the transmit DMA logic. The driver handles the transmit
+completion in the context of the interrupt handling chain by recycling
+resource required to send and track the requested transmit operation.
+
+4.2. Receive process
+--------------------
+The driver will post receive buffers to the receive DMA logic during driver
+initialization. Receive buffers may or may not be queued depending upon the
+underlying DMA logic (MSGDMA is able queue receive buffers, SGDMA is not able
+to queue receive buffers to the SGDMA receive logic). When a packet is
+received, the DMA logic generates an interrupt. The driver handles a receive
+interrupt by obtaining the DMA receive logic status, reaping receive
+completions until no more receive completions are available.
+
+4.3. Interrupt Mitigation
+-------------------------
+The driver is able to mitigate the number of its DMA interrupts
+using NAPI for receive operations. Interrupt mitigation is not yet supported
+for transmit operations, but will be added in a future maintenance release.
+
+4.4) Ethtool support
+--------------------
+Ethtool is supported. Driver statistics and internal errors can be taken using:
+ethtool -S ethX command. It is possible to dump registers etc.
+
+4.5) PHY Support
+----------------
+The driver is compatible with PAL to work with PHY and GPHY devices.
+
+4.7) List of source files:
+--------------------------
+ - Kconfig
+ - Makefile
+ - altera_tse_main.c: main network device driver
+ - altera_tse_ethtool.c: ethtool support
+ - altera_tse.h: private driver structure and common definitions
+ - altera_msgdma.h: MSGDMA implementation function definitions
+ - altera_sgdma.h: SGDMA implementation function definitions
+ - altera_msgdma.c: MSGDMA implementation
+ - altera_sgdma.c: SGDMA implementation
+ - altera_sgdmahw.h: SGDMA register and descriptor definitions
+ - altera_msgdmahw.h: MSGDMA register and descriptor definitions
+ - altera_utils.c: Driver utility functions
+ - altera_utils.h: Driver utility function definitions
+
+5. Debug Information
+====================
+
+The driver exports debug information such as internal statistics,
+debug information, MAC and DMA registers etc.
+
+A user may use the ethtool support to get statistics:
+e.g. using: ethtool -S ethX (that shows the statistics counters)
+or sees the MAC registers: e.g. using: ethtool -d ethX
+
+The developer can also use the "debug" module parameter to get
+further debug information.
+
+6. Statistics Support
+=====================
+
+The controller and driver support a mix of IEEE standard defined statistics,
+RFC defined statistics, and driver or Altera defined statistics. The four
+specifications containing the standard definitions for these statistics are
+as follows:
+
+ - IEEE 802.3-2012 - IEEE Standard for Ethernet.
+ - RFC 2863 found at http://www.rfc-editor.org/rfc/rfc2863.txt.
+ - RFC 2819 found at http://www.rfc-editor.org/rfc/rfc2819.txt.

-========================================
-The COPS LocalTalk Linux driver (cops.c)
-========================================
-
-By Jay Schulist <jschlst@samba.org>
-
-This driver has two modes and they are: Dayna mode and Tangent mode.
-Each mode corresponds with the type of card. It has been found
-that there are 2 main types of cards and all other cards are
-the same and just have different names or only have minor differences
-such as more IO ports. As this driver is tested it will
-become more clear exactly what cards are supported.
-
-Right now these cards are known to work with the COPS driver. The
-LT-200 cards work in a somewhat more limited capacity than the
-DL200 cards, which work very well and are in use by many people.
-
-TANGENT driver mode:
-	- Tangent ATB-II, Novell NL-1000, Daystar Digital LT-200
-
-DAYNA driver mode:
-	- Dayna DL2000/DaynaTalk PC (Half Length), COPS LT-95,
-	- Farallon PhoneNET PC III, Farallon PhoneNET PC II
-
-Other cards possibly supported mode unknown though:
-	- Dayna DL2000 (Full length)
-
-The COPS driver defaults to using Dayna mode. To change the driver's
-mode if you built a driver with dual support use board_type=1 or
-board_type=2 for Dayna or Tangent with insmod.
-
-Operation/loading of the driver
-===============================
-
-Use modprobe like this:	/sbin/modprobe cops.o (IO #) (IRQ #)
-If you do not specify any options the driver will try and use the IO = 0x240,
-IRQ = 5. As of right now I would only use IRQ 5 for the card, if autoprobing.
-
-To load multiple COPS driver Localtalk cards you can do one of the following::
-
-	insmod cops io=0x240 irq=5
-	insmod -o cops2 cops io=0x260 irq=3
-
-Or in lilo.conf put something like this::
-
-	append="ether=5,0x240,lt0 ether=3,0x260,lt1"
-
-Then bring up the interface with ifconfig. It will look something like this::
-
-  lt0       Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-F7-00-00-00-00-00-00-00-00
-	    inet addr:192.168.1.2  Bcast:192.168.1.255  Mask:255.255.255.0
-	    UP BROADCAST RUNNING NOARP MULTICAST  MTU:600  Metric:1
-	    RX packets:0 errors:0 dropped:0 overruns:0 frame:0
-	    TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 coll:0
-
-Netatalk Configuration
-======================
-
-You will need to configure atalkd with something like the following to make
-it work with the cops.c driver.
-
-* For single LTalk card use::
-
-    dummy -seed -phase 2 -net 2000 -addr 2000.10 -zone "1033"
-    lt0 -seed -phase 1 -net 1000 -addr 1000.50 -zone "1033"
-
-* For multiple cards, Ethernet and LocalTalk::
-
-    eth0 -seed -phase 2 -net 3000 -addr 3000.20 -zone "1033"
-    lt0 -seed -phase 1 -net 1000 -addr 1000.50 -zone "1033"
-
-* For multiple LocalTalk cards, and an Ethernet card.
-
-* Order seems to matter here, Ethernet last::
-
-    lt0 -seed -phase 1 -net 1000 -addr 1000.10 -zone "LocalTalk1"
-    lt1 -seed -phase 1 -net 2000 -addr 2000.20 -zone "LocalTalk2"

+
+===========
+LTPC Driver
+===========
+
+This is the ALPHA version of the ltpc driver.
+
+In order to use it, you will need at least version 1.3.3 of the
+netatalk package, and the Apple or Farallon LocalTalk PC card.
+There are a number of different LocalTalk cards for the PC; this
+driver applies only to the one with the 65c02 processor chip on it.
+
+To include it in the kernel, select the CONFIG_LTPC switch in the
+configuration dialog.  You can also compile it as a module.
+
+While the driver will attempt to autoprobe the I/O port address, IRQ
+line, and DMA channel of the card, this does not always work.  For
+this reason, you should be prepared to supply these parameters
+yourself.  (see "Card Configuration" below for how to determine or
+change the settings on your card)
+
+When the driver is compiled into the kernel, you can add a line such
+as the following to your /etc/lilo.conf::
+
+ append="ltpc=0x240,9,1"
+
+where the parameters (in order) are the port address, IRQ, and DMA
+channel.  The second and third values can be omitted, in which case
+the driver will try to determine them itself.
+
+If you load the driver as a module, you can pass the parameters "io=",
+"irq=", and "dma=" on the command line with insmod or modprobe, or add
+them as options in a configuration file in /etc/modprobe.d/ directory::
+
+ alias lt0 ltpc # autoload the module when the interface is configured
+ options ltpc io=0x240 irq=9 dma=1
+
+Before starting up the netatalk demons (perhaps in rc.local), you
+need to add a line such as::
+
+ /sbin/ifconfig lt0 127.0.0.42
+
+The address is unimportant - however, the card needs to be configured
+with ifconfig so that Netatalk can find it.
+
+The appropriate netatalk configuration depends on whether you are
+attached to a network that includes AppleTalk routers or not.  If,
+like me, you are simply connecting to your home Macintoshes and
+printers, you need to set up netatalk to "seed".  The way I do this
+is to have the lines::
+
+ dummy -seed -phase 2 -net 2000 -addr 2000.26 -zone "1033"
+ lt0 -seed -phase 1 -net 1033 -addr 1033.27 -zone "1033"
+
+in my atalkd.conf.  What is going on here is that I need to fool
+netatalk into thinking that there are two AppleTalk interfaces
+present; otherwise, it refuses to seed.  This is a hack, and a more
+permanent solution would be to alter the netatalk code.  Also, make
+sure you have the correct name for the dummy interface - If it's
+compiled as a module, you will need to refer to it as "dummy0" or some
+such.
+
+If you are attached to an extended AppleTalk network, with routers on
+it, then you don't need to fool around with this -- the appropriate
+line in atalkd.conf is::
+
+ lt0 -phase 1
+
+
+Card Configuration
+==================
+
+The interrupts and so forth are configured via the dipswitch on the
+board.  Set the switches so as not to conflict with other hardware.
+
+       Interrupts -- set at most one.  If none are set, the driver uses
+       polled mode.  Because the card was developed in the XT era, the
+       original documentation refers to IRQ2.  Since you'll be running
+       this on an AT (or later) class machine, that really means IRQ9.
+
+       ===     ===========================================================
+       SW1     IRQ 4
+       SW2     IRQ 3
+       SW3     IRQ 9 (2 in original card documentation only applies to XT)
+       ===     ===========================================================
+
+
+       DMA -- choose DMA 1 or 3, and set both corresponding switches.
+
+       ===     =====
+       SW4     DMA 3
+       SW5     DMA 1
+       SW6     DMA 3
+       SW7     DMA 1
+       ===     =====
+
+
+       I/O address -- choose one.
+
+       ===     =========
+       SW8     220 / 240
+       ===     =========
+
+
+IP
+==
+
+Yes, it is possible to do IP over LocalTalk.  However, you can't just
+treat the LocalTalk device like an ordinary Ethernet device, even if
+that's what it looks like to Netatalk.
+
+Instead, you follow the same procedure as for doing IP in EtherTalk.
+See Documentation/networking/ipddp.rst for more information about the
+kernel driver and userspace tools needed.
+
+
+Bugs
+====
+
+IRQ autoprobing often doesn't work on a cold boot.  To get around
+this, either compile the driver as a module, or pass the parameters
+for the card to the kernel as described above.
+
+Also, as usual, autoprobing is not recommended when you use the driver
+as a module. (though it usually works at boot time, at least)
+
+Polled mode is *really* slow sometimes, but this seems to depend on
+the configuration of the network.
+
+It may theoretically be possible to use two LTPC cards in the same
+machine, but this is unsupported, so if you really want to do this,
+you'll probably have to hack the initialization code a bit.
+
+
+Thanks
+======
+
+Thanks to Alan Cox for helpful discussions early on in this
+work, and to Denis Hainsworth for doing the bleeding-edge testing.

-printers, you need to set up netatalk to "seed".  The way I do this
-is to have the lines::
-
- dummy -seed -phase 2 -net 2000 -addr 2000.26 -zone "1033"
- lt0 -seed -phase 1 -net 1033 -addr 1033.27 -zone "1033"
-
-in my atalkd.conf.  What is going on here is that I need to fool
-netatalk into thinking that there are two AppleTalk interfaces
-present; otherwise, it refuses to seed.  This is a hack, and a more
-permanent solution would be to alter the netatalk code.  Also, make
-sure you have the correct name for the dummy interface - If it's
-compiled as a module, you will need to refer to it as "dummy0" or some
-such.
-
-If you are attached to an extended AppleTalk network, with routers on
-it, then you don't need to fool around with this -- the appropriate
-line in atalkd.conf is::
-
- lt0 -phase 1
-
-
-Card Configuration
-==================
-
-The interrupts and so forth are configured via the dipswitch on the
-board.  Set the switches so as not to conflict with other hardware.
-
-       Interrupts -- set at most one.  If none are set, the driver uses
-       polled mode.  Because the card was developed in the XT era, the
-       original documentation refers to IRQ2.  Since you'll be running
-       this on an AT (or later) class machine, that really means IRQ9.
-
-       ===     ===========================================================
-       SW1     IRQ 4
-       SW2     IRQ 3
-       SW3     IRQ 9 (2 in original card documentation only applies to XT)
-       ===     ===========================================================
-
-
-       DMA -- choose DMA 1 or 3, and set both corresponding switches.
-
-       ===     =====
-       SW4     DMA 3
-       SW5     DMA 1
-       SW6     DMA 3
-       SW7     DMA 1
-       ===     =====
-
-
-       I/O address -- choose one.
-
-       ===     =========
-       SW8     220 / 240
-       ===     =========
-
-
-IP
-==
-
-Yes, it is possible to do IP over LocalTalk.  However, you can't just
-treat the LocalTalk device like an ordinary Ethernet device, even if
-that's what it looks like to Netatalk.
-
-Instead, you follow the same procedure as for doing IP in EtherTalk.
-See Documentation/networking/ipddp.rst for more information about the
-kernel driver and userspace tools needed.
-
-
-Bugs
-====
-
-IRQ autoprobing often doesn't work on a cold boot.  To get around
-this, either compile the driver as a module, or pass the parameters
-for the card to the kernel as described above.
-
-Also, as usual, autoprobing is not recommended when you use the driver
-as a module. (though it usually works at boot time, at least)
-
-Polled mode is *really* slow sometimes, but this seems to depend on
-the configuration of the network.
-
-It may theoretically be possible to use two LTPC cards in the same
-machine, but this is unsupported, so if you really want to do this,
-you'll probably have to hack the initialization code a bit.
-
-
-Thanks
-======
-
-Thanks to Alan Cox for helpful discussions early on in this
-work, and to Denis Hainsworth for doing the bleeding-edge testing.

-ATM cxacru device driver
-========================
-
-Firmware is required for this device: http://accessrunner.sourceforge.net/
-
-While it is capable of managing/maintaining the ADSL connection without the
-module loaded, the device will sometimes stop responding after unloading the
-driver and it is necessary to unplug/remove power to the device to fix this.
-
-Note: support for cxacru-cf.bin has been removed. It was not loaded correctly
-so it had no effect on the device configuration. Fixing it could have stopped
-existing devices working when an invalid configuration is supplied.
-
-There is a script cxacru-cf.py to convert an existing file to the sysfs form.
-
-Detected devices will appear as ATM devices named "cxacru". In /sys/class/atm/
-these are directories named cxacruN where N is the device number. A symlink

+=============================================
+FORE Systems PCA-200E/SBA-200E ATM NIC driver
+=============================================
+
+This driver adds support for the FORE Systems 200E-series ATM adapters
+to the Linux operating system. It is based on the earlier PCA-200E driver
+written by Uwe Dannowski.
+
+The driver simultaneously supports PCA-200E and SBA-200E adapters on
+i386, alpha (untested), powerpc, sparc and sparc64 archs.
+
+The intent is to enable the use of different models of FORE adapters at the
+same time, by hosts that have several bus interfaces (such as PCI+SBUS,
+or PCI+EISA).
+
+Only PCI and SBUS devices are currently supported by the driver, but support
+for other bus interfaces such as EISA should not be too hard to add.
+
+
+Firmware Copyright Notice
+-------------------------
+
+Please read the fore200e_firmware_copyright file present
+in the linux/drivers/atm directory for details and restrictions.
+
+
+Firmware Updates
+----------------
+
+The FORE Systems 200E-series driver is shipped with firmware data being
+uploaded to the ATM adapters at system boot time or at module loading time.
+The supplied firmware images should work with all adapters.
+
+However, if you encounter problems (the firmware doesn't start or the driver
+is unable to read the PROM data), you may consider trying another firmware
+version. Alternative binary firmware images can be found somewhere on the
+ForeThought CD-ROM supplied with your adapter by FORE Systems.
+
+You can also get the latest firmware images from FORE Systems at
+https://en.wikipedia.org/wiki/FORE_Systems. Register TACTics Online and go to
+the 'software updates' pages. The firmware binaries are part of
+the various ForeThought software distributions.
+
+Notice that different versions of the PCA-200E firmware exist, depending
+on the endianness of the host architecture. The driver is shipped with
+both little and big endian PCA firmware images.
+
+Name and location of the new firmware images can be set at kernel
+configuration time:
+
+1. Copy the new firmware binary files (with .bin, .bin1 or .bin2 suffix)
+   to some directory, such as linux/drivers/atm.
+
+2. Reconfigure your kernel to set the new firmware name and location.
+   Expected pathnames are absolute or relative to the drivers/atm directory.
+
+3. Rebuild and re-install your kernel or your module.
+
+

+Before You Start
+================
+
+
+Installation
+------------
+
+1. Installing the adapters in the system
+
+   To install the ATM adapters in the system, follow the steps below.
+
+       a. Login as root.
+       b. Shut down the system and power off the system.
+       c. Install one or more ATM adapters in the system.
+       d. Connect each adapter to a port on an ATM switch. The green 'Link'
+	  LED on the front panel of the adapter will be on if the adapter is
+	  connected to the switch properly when the system is powered up.
+       e. Power on and boot the system.
+
+2. [ Removed ]
+
+3. Rebuild kernel with ABR support
+
+   [ a. and b. removed ]
+
+    c. Reconfigure the kernel, choose the Interphase ia driver through "make
+       menuconfig" or "make xconfig".
+    d. Rebuild the kernel, loadable modules and the atm tools.
+    e. Install the new built kernel and modules and reboot.
+
+4. Load the adapter hardware driver (ia driver) if it is built as a module
+
+       a. Login as root.
+       b. Change directory to /lib/modules/<kernel-version>/atm.
+       c. Run "insmod suni.o;insmod iphase.o"
+	  The yellow 'status' LED on the front panel of the adapter will blink
+	  while the driver is loaded in the system.
+       d. To verify that the 'ia' driver is loaded successfully, run the
+	  following command::
+
+	      cat /proc/atm/devices
+
+	  If the driver is loaded successfully, the output of the command will
+	  be similar to the following lines::
+
+	      Itf Type    ESI/"MAC"addr AAL(TX,err,RX,err,drop) ...
+	      0   ia      xxxxxxxxx  0 ( 0 0 0 0 0 )  5 ( 0 0 0 0 0 )
+
+	  You can also check the system log file /var/log/messages for messages
+	  related to the ATM driver.
+
+5. Ia Driver Configuration
+
+5.1 Configuration of adapter buffers
+    The (i)Chip boards have 3 different packet RAM size variants: 128K, 512K and
+    1M. The RAM size decides the number of buffers and buffer size. The default
+    size and number of buffers are set as following:
+
+	=========  =======  ======   ======   ======   ======   ======
+	 Total     Rx RAM   Tx RAM   Rx Buf   Tx Buf   Rx buf   Tx buf
+	 RAM size  size     size     size     size     cnt      cnt
+	=========  =======  ======   ======   ======   ======   ======
+	   128K      64K      64K      10K      10K       6        6
+	   512K     256K     256K      10K      10K      25       25
+	     1M     512K     512K      10K      10K      51       51
+	=========  =======  ======   ======   ======   ======   ======
+
+       These setting should work well in most environments, but can be
+       changed by typing the following command::
+
+	   insmod <IA_DIR>/ia.o IA_RX_BUF=<RX_CNT> IA_RX_BUF_SZ=<RX_SIZE> \
+		   IA_TX_BUF=<TX_CNT> IA_TX_BUF_SZ=<TX_SIZE>
+
+       Where:
+
+	    - RX_CNT = number of receive buffers in the range (1-128)
+	    - RX_SIZE = size of receive buffers in the range (48-64K)
+	    - TX_CNT = number of transmit buffers in the range (1-128)
+	    - TX_SIZE = size of transmit buffers in the range (48-64K)
+
+	    1. Transmit and receive buffer size must be a multiple of 4.
+	    2. Care should be taken so that the memory required for the
+	       transmit and receive buffers is less than or equal to the
+	       total adapter packet memory.
+
+5.2 Turn on ia debug trace
+
+    When the ia driver is built with the CONFIG_ATM_IA_DEBUG flag, the driver
+    can provide more debug trace if needed. There is a bit mask variable,
+    IADebugFlag, which controls the output of the traces. You can find the bit
+    map of the IADebugFlag in iphase.h.
+    The debug trace can be turn on through the insmod command line option, for
+    example, "insmod iphase.o IADebugFlag=0xffffffff" can turn on all the debug
+    traces together with loading the driver.
+
+6. Ia Driver Test Using ttcp_atm and PVC
+
+   For the PVC setup, the test machines can either be connected back-to-back or
+   through a switch. If connected through the switch, the switch must be
+   configured for the PVC(s).
+
+   a. For UBR test:
+
+      At the test machine intended to receive data, type::
+
+	 ttcp_atm -r -a -s 0.100
+
+      At the other test machine, type::
+
+	 ttcp_atm -t -a -s 0.100 -n 10000
+
+      Run "ttcp_atm -h" to display more options of the ttcp_atm tool.
+   b. For ABR test:
+
+      It is the same as the UBR testing, but with an extra command option::
+
+	 -Pabr:max_pcr=<xxx>
+
+      where:
+
+	     xxx = the maximum peak cell rate, from 170 - 353207.
+
+      This option must be set on both the machines.
+
+   c. For CBR test:
+
+      It is the same as the UBR testing, but with an extra command option::
+
+	 -Pcbr:max_pcr=<xxx>
+
+      where:
+
+	     xxx = the maximum peak cell rate, from 170 - 353207.
+
+      This option may only be set on the transmit machine.

-FORE Systems PCA-200E/SBA-200E ATM NIC driver
-=============================================
-
-This driver adds support for the FORE Systems 200E-series ATM adapters
-to the Linux operating system. It is based on the earlier PCA-200E driver
-written by Uwe Dannowski.
-
-The driver simultaneously supports PCA-200E and SBA-200E adapters on
-i386, alpha (untested), powerpc, sparc and sparc64 archs.
-
-The intent is to enable the use of different models of FORE adapters at the
-same time, by hosts that have several bus interfaces (such as PCI+SBUS,
-or PCI+EISA).
-
-Only PCI and SBUS devices are currently supported by the driver, but support
-for other bus interfaces such as EISA should not be too hard to add.
-
-
-Firmware Copyright Notice
--------------------------
-
-Please read the fore200e_firmware_copyright file present
-in the linux/drivers/atm directory for details and restrictions.
-
-
-Firmware Updates
-----------------
-
-The FORE Systems 200E-series driver is shipped with firmware data being
-uploaded to the ATM adapters at system boot time or at module loading time.
-The supplied firmware images should work with all adapters.
-
-However, if you encounter problems (the firmware doesn't start or the driver
-is unable to read the PROM data), you may consider trying another firmware
-version. Alternative binary firmware images can be found somewhere on the
-ForeThought CD-ROM supplied with your adapter by FORE Systems.
-
-You can also get the latest firmware images from FORE Systems at
-https://en.wikipedia.org/wiki/FORE_Systems. Register TACTics Online and go to
-the 'software updates' pages. The firmware binaries are part of
-the various ForeThought software distributions.
-
-Notice that different versions of the PCA-200E firmware exist, depending
-on the endianness of the host architecture. The driver is shipped with
-both little and big endian PCA firmware images.
-
-Name and location of the new firmware images can be set at kernel
-configuration time:
-
-1. Copy the new firmware binary files (with .bin, .bin1 or .bin2 suffix)
-   to some directory, such as linux/drivers/atm.
-
-2. Reconfigure your kernel to set the new firmware name and location.
-   Expected pathnames are absolute or relative to the drivers/atm directory.
-
-3. Rebuild and re-install your kernel or your module.

-=====================================================
-Notes on the DEC FDDIcontroller 700 (DEFZA-xx) driver
-=====================================================
-
-:Version: v.1.1.4
-
-
-DEC FDDIcontroller 700 is DEC's first-generation TURBOchannel FDDI
-network card, designed in 1990 specifically for the DECstation 5000
-model 200 workstation.  The board is a single attachment station and
-it was manufactured in two variations, both of which are supported.
-
-First is the SAS MMF DEFZA-AA option, the original design implementing
-the standard MMF-PMD, however with a pair of ST connectors rather than
-the usual MIC connector.  The other one is the SAS ThinWire/STP DEFZA-CA
-option, denoted 700-C, with the network medium selectable by a switch
-between the DEC proprietary ThinWire-PMD using a BNC connector and the
-standard STP-PMD using a DE-9F connector.  This option can interface to
-a DECconcentrator 500 device and, in the case of the STP-PMD, also other
-FDDI equipment and was designed to make it easier to transition from
-existing IEEE 802.3 10BASE2 Ethernet and IEEE 802.5 Token Ring networks
-by providing means to reuse existing cabling.
-
-This driver handles any number of cards installed in a single system.
-They get fddi0, fddi1, etc. interface names assigned in the order of
-increasing TURBOchannel slot numbers.
-
-The board only supports DMA on the receive side.  Transmission involves
-the use of PIO.  As a result under a heavy transmission load there will
-be a significant impact on system performance.
-
-The board supports a 64-entry CAM for matching destination addresses.
-Two entries are preoccupied by the Directed Beacon and Ring Purger
-multicast addresses and the rest is used as a multicast filter.  An
-all-multi mode is also supported for LLC frames and it is used if
-requested explicitly or if the CAM overflows.  The promiscuous mode
-supports separate enables for LLC and SMT frames, but this driver
-doesn't support changing them individually.
-
-
-Known problems:
-
-None.

+=====================================================
+Notes on the DEC FDDIcontroller 700 (DEFZA-xx) driver
+=====================================================
+
+:Version: v.1.1.4
+
+
+DEC FDDIcontroller 700 is DEC's first-generation TURBOchannel FDDI
+network card, designed in 1990 specifically for the DECstation 5000
+model 200 workstation.  The board is a single attachment station and
+it was manufactured in two variations, both of which are supported.
+
+First is the SAS MMF DEFZA-AA option, the original design implementing
+the standard MMF-PMD, however with a pair of ST connectors rather than
+the usual MIC connector.  The other one is the SAS ThinWire/STP DEFZA-CA
+option, denoted 700-C, with the network medium selectable by a switch
+between the DEC proprietary ThinWire-PMD using a BNC connector and the
+standard STP-PMD using a DE-9F connector.  This option can interface to
+a DECconcentrator 500 device and, in the case of the STP-PMD, also other
+FDDI equipment and was designed to make it easier to transition from
+existing IEEE 802.3 10BASE2 Ethernet and IEEE 802.5 Token Ring networks
+by providing means to reuse existing cabling.
+
+This driver handles any number of cards installed in a single system.
+They get fddi0, fddi1, etc. interface names assigned in the order of
+increasing TURBOchannel slot numbers.
+
+The board only supports DMA on the receive side.  Transmission involves
+the use of PIO.  As a result under a heavy transmission load there will
+be a significant impact on system performance.
+
+The board supports a 64-entry CAM for matching destination addresses.
+Two entries are preoccupied by the Directed Beacon and Ring Purger
+multicast addresses and the rest is used as a multicast filter.  An
+all-multi mode is also supported for LLC frames and it is used if
+requested explicitly or if the CAM overflows.  The promiscuous mode
+supports separate enables for LLC and SMT frames, but this driver
+doesn't support changing them individually.
+
+
+Known problems:
+
+None.
+
+
+To do:
+
+5. MAC address change.  The card does not support changing the Media
+   Access Controller's address registers but a similar effect can be
+   achieved by adding an alias to the CAM.  There is no way to disable
+   matching against the original address though.
+
+7. Queueing incoming/outgoing SMT frames in the driver if the SMT
+   receive/RMC transmit ring is full. (?)
+
+8. Retrieving/reporting FDDI/SNMP stats.
+
+
+Both success and failure reports are welcome.

+1. Overview
+===========
+
+This README explains how to use the driver 'skfp' for Linux with your
+network adapter.
+
+Chapter 2: Contains a list of all network adapters that are supported by
+this driver.
+
+Chapter 3:
+	   Gives some general information.
+
+Chapter 4: Describes common problems and solutions.
+
+Chapter 5: Shows the changed functionality of the adapter LEDs.
+
+Chapter 6: History of development.
+
+
+2. Supported adapters
+=====================
+
+The network driver 'skfp' supports the following network adapters:
+SysKonnect adapters:
+
+  - SK-5521 (SK-NET FDDI-UP)
+  - SK-5522 (SK-NET FDDI-UP DAS)
+  - SK-5541 (SK-NET FDDI-FP)
+  - SK-5543 (SK-NET FDDI-LP)
+  - SK-5544 (SK-NET FDDI-LP DAS)
+  - SK-5821 (SK-NET FDDI-UP64)
+  - SK-5822 (SK-NET FDDI-UP64 DAS)
+  - SK-5841 (SK-NET FDDI-FP64)
+  - SK-5843 (SK-NET FDDI-LP64)
+  - SK-5844 (SK-NET FDDI-LP64 DAS)
+
+Compaq adapters (not tested):
+
+  - Netelligent 100 FDDI DAS Fibre SC
+  - Netelligent 100 FDDI SAS Fibre SC
+  - Netelligent 100 FDDI DAS UTP
+  - Netelligent 100 FDDI SAS UTP
+  - Netelligent 100 FDDI SAS Fibre MIC
+
+
+3. General Information
+======================
+
+From v2.01 on, the driver is integrated in the linux kernel sources.
+Therefore, the installation is the same as for any other adapter
+supported by the kernel.
+
+Refer to the manual of your distribution about the installation
+of network adapters.
+
+Makes my life much easier :-)
+
+4. Troubleshooting
+==================
+
+If you run into problems during installation, check those items:
+
+Problem:
+	  The FDDI adapter cannot be found by the driver.
+
+Reason:
+	  Look in /proc/pci for the following entry:
+
+	     'FDDI network controller: SysKonnect SK-FDDI-PCI ...'
+
+	  If this entry exists, then the FDDI adapter has been
+	  found by the system and should be able to be used.
+
+	  If this entry does not exist or if the file '/proc/pci'
+	  is not there, then you may have a hardware problem or PCI
+	  support may not be enabled in your kernel.
+
+	  The adapter can be checked using the diagnostic program
+	  which is available from the SysKonnect web site:
+
+	      www.syskonnect.de
+
+	  Some COMPAQ machines have a problem with PCI under
+	  Linux. This is described in the 'PCI howto' document
+	  (included in some distributions or available from the
+	  www, e.g. at 'www.linux.org') and no workaround is available.
+
+Problem:
+	  You want to use your computer as a router between
+	  multiple IP subnetworks (using multiple adapters), but
+	  you cannot reach computers in other subnetworks.
+
+Reason:
+	  Either the router's kernel is not configured for IP
+	  forwarding or there is a problem with the routing table
+	  and gateway configuration in at least one of the
+	  computers.
+
+If your problem is not listed here, please contact our
+technical support for help.
+
+You can send email to: linux@syskonnect.de
+
+When contacting our technical support,
+please ensure that the following information is available:
+
+- System Manufacturer and Model
+- Boards in your system
+- Distribution
+- Kernel version
+
+
+5. Function of the Adapter LEDs
+===============================
+
+	The functionality of the LED's on the FDDI network adapters was
+	changed in SMT version v2.82. With this new SMT version, the yellow
+	LED works as a ring operational indicator. An active yellow LED
+	indicates that the ring is down. The green LED on the adapter now
+	works as a link indicator where an active GREEN LED indicates that
+	the respective port has a physical connection.
+
+	With versions of SMT prior to v2.82 a ring up was indicated if the
+	yellow LED was off while the green LED(s) showed the connection
+	status of the adapter. During a ring down the green LED was off and
+	the yellow LED was on.
+
+	All implementations indicate that a driver is not loaded if
+	all LEDs are off.
+
+

From 2c5ebd001d4f0c64a2dfda94eb1d9b31a8863c8d Mon Sep 17 00:00:00 2001
From: Paolo Abeni <pabeni@redhat.com>
Date: Fri, 26 Jun 2020 19:30:00 +0200
Subject: mptcp: refactor token container

Replace the radix tree with a hash table allocated
at boot time. The radix tree has some shortcoming:
a single lock is contented by all the mptcp operation,
the lookup currently use such lock, and traversing
all the items would require a lock, too.

With hash table instead we trade a little memory to
address all the above - a per bucket lock is used.

To hash the MPTCP sockets, we re-use the msk' sk_node
entry: the MPTCP sockets are never hashed by the stack.
Replace the existing hash proto callbacks with a dummy
implementation, annotating the above constraint.

Additionally refactor the token creation to code to:

- limit the number of consecutive attempts to a fixed
maximum. Hitting a hash bucket with a long chain is
considered a failed attempt

- accept() no longer can fail to token management.

- if token creation fails at connect() time, we do
fallback to TCP (before the connection was closed)

v1 -> v2:
 - fix "no newline at end of file" - Jakub

Subject: mptcp: move crypto test to KUNIT

currently MPTCP uses a custom hook to executed unit tests at
boot time. Let's use the KUNIT framework instead.
Additionally move the relevant code to a separate file and
export the function needed by the test when self-tests
are build as a module.

Subject: net: atlantic: add alignment checks in hw_atl2_utils_fw.c

This patch adds alignment checks in all the helper macros in
hw_atl2_utils_fw.c
These alignment checks are compile-time, so runtime is not affected.

All these helper macros assume the length to be aligned (multiple of 4).
If it's not aligned, then there might be issues, e.g. stack corruption.

Subject: net: atlantic: put ptp code under IS_REACHABLE check

A1 requires additional processing for both egress and ingress to support
PTP.
And it makes sense to get rid of this processing altogether (via ifdef),
if PTP clock is disabled globally.

This patch puts the PTP code under the corresponding IS_REACHABLE check.

Flow steering core layer is independent of the eswitch layer.
Hence avoid fs_core dependency on eswitch.

Subject: net/mlx5: kTLS, Improve TLS params layout structures

Add explicit WQE segment structures for the TLS static and progress
params.
According to the HW spec, TISN is not part of the progress params context,
take it out of it.
Rename the control segment tisn field as it could hold either a TIS or
a TIR number.

Subject: net/mlx5e: Turn XSK ICOSQ into a general asynchronous one

There is an upcoming demand (in downstream patches) for
an ICOSQ to be populated out of the NAPI context, asynchronously.

There is already an existing one serving XSK-related use case.
In this patch, promote this ICOSQ to serve as general async ICOSQ,
to be used for XSK and non-XSK flows.

As part of this, the reg_umr bit of the SQ context is now set
(if capable), as the general async ICOSQ should support possible
posts of UMR WQEs.

Subject: net/mlx5e: Refactor build channel params

Take the CQ params into their respective RQ/SQ params.
Split the params build of the different ICOSQs (sync and async),
as they require different init values.

Subject: net/mlx5e: API to manipulate TTC rules destinations

Store the default destinations of the on-load generated TTC
(Traffic Type Classifier) rules in the ttc rules table.

Introduce TTC API functions to manipulate/restore and get the TTC rule
destination and use these API functions in arfs implementation.

This will allow a better decoupling between TTC implementation and its
users.

From c062d52ac24ceea0b4a5fbdc70c5cff1e47a0e49 Mon Sep 17 00:00:00 2001
From: Boris Pismenny <borisp@mellanox.com>

Subject: net/mlx5e: Receive flow steering framework for accelerated TCP flows

The framework allows creating flow tables to steer incoming traffic of
TCP sockets to the acceleration TIRs.
This is used in downstream patches for TLS, and will be used in the
future for other offloads.

Subject: net/mlx5e: Accel, Expose flow steering API for rules add/del

Given a socket, the function extracts the TCP/IP{4,6} ntuple
and adds rule to steering.
Another function gets the rule and deletes it.

From 7d0d0d86ec6c67d3eb4f49d3bbccc2d8c02799cc Mon Sep 17 00:00:00 2001
From: Tariq Toukan <tariqt@mellanox.com>
Date: Tue, 26 May 2020 13:58:09 +0300
Subject: net/mlx5e: kTLS, Improve TLS feature modularity

Better separate the code into c/h files, so that kTLS internals
are exposed to the corresponding non-accel flow as follows:
- Necessary datapath functions are exposed via ktls_txrx.h.
- Necessary caps and configuration functions are exposed via ktls.h,
  which became very small.

In addition, kTLS internal code sharing is done via ktls_utils.h,
which is not exposed to any non-accel file.

Add explicit WQE structures for the TLS static and progress
params, breaking the union of the static with UMR, and the progress
with PSV.

Generalize the API as a preparation for TLS RX offload support.

Move kTLS TX-specific code to the proper file.
Remove the inline tag for function in C files, let the compiler decide.
Use kzalloc/kfree for the priv_tx context.

Subject: net/mlx5e: kTLS, Use kernel API to extract private offload context

Modify the implementation of the private kTLS TX HW offload context
getter and setter, so it uses the kernel API functions, instead of
a local shadow structure.
A single BUILD_BUG_ON check is sufficient, remove the duplicate.

Subject: net/mlx5e: kTLS, Add kTLS RX HW offload support

Implement driver support for the kTLS RX HW offload feature.
Resync support is added in a downstream patch.

New offload contexts post their static/progress params WQEs
over the per-channel async ICOSQ, protected under a spin-lock.
The Channel/RQ is selected according to the socket's rxq index.

Feature is OFF by default. Can be turned on by:
$ ethtool -K <if> tls-hw-rx-offload on

A new TLS-RX workqueue is used to allow asynchronous addition of
steering rules, out of the NAPI context.
It will be also used in a downstream patch in the resync procedure.

Subject: net/tls: Add asynchronous resync

This patch adds support for asynchronous resynchronization in tls_device.
Async resync follows two distinct stages:

1. The NIC driver indicates that it would like to resync on some TLS
record within the received packet (P), but the driver does not
know (yet) which of the TLS records within the packet.
At this stage, the NIC driver will query the device to find the exact
TCP sequence for resync (tcpsn), however, the driver does not wait
for the device to provide the response.

2. Eventually, the device responds, and the driver provides the tcpsn
within the resync packet to KTLS. Now, KTLS can check the tcpsn against
any processed TLS records within packet P, and also against any record
that is processed in the future within packet P.

The asynchronous resync path simplifies the device driver, as it can
save bits on the packet completion (32-bit TCP sequence), and pass this
information on an asynchronous command instead.

Subject: net/mlx5e: kTLS, Add kTLS RX resync support

Implement the RX resync procedure, using the TLS async resync API.

The HW offload of TLS decryption in RX side might get out-of-sync
due to out-of-order reception of packets.
This requires SW intervention to update the HW context and get it
back in-sync.

Performance:
CPU: Intel(R) Xeon(R) CPU E5-2687W v4 @ 3.00GHz, 24 cores, HT off
NIC: ConnectX-6 Dx 100GbE dual port

Goodput (app-layer throughput) comparison:

| # connections |   1   |   4   |    8    |
+---------------+-------+-------+---------+
| SW (Gbps)     |  7.26 | 24.70 |   50.30 |
+---------------+-------+-------+---------+
| HW (Gbps)     | 18.50 | 64.30 |   92.90 |
+---------------+-------+-------+---------+
| Speedup       | 2.55x | 2.56x | 1.85x * |
+---------------+-------+-------+---------+

* After linerate is reached, diff is observed in CPU util.

Subject: net/mlx5e: Increase Async ICO SQ size

Resync communication with HW for kTLS RX is done via the
async ICOSQs.
kTLS RX resync requests might come in bursts. To improve the
success chances for such bursts, use a larger ICOSQ.

Subject: net/mlx5e: kTLS, Improve rx handler function call

Prior to this patch mlx5e tls rx handler was called unconditionally on
all rx frames and the decision whether a frame is a valid tls record
is done inside that function.  A function call can be expensive especially
for regular rx packet rate.  To avoid this, check the tls validity before
jumping into the tls rx handler.

While at it, split between kTLS device offload rx handler and FPGA tls rx
handler using a similar method.

Subject: tcp: stamp SCM_TSTAMP_ACK later in tcp_clean_rtx_queue()

Currently tp->delivered is updated with sacked packets but not
cumulatively acked when SCP_TSTAMP_ACK is timestamped. This patch moves
a tcp_ack_tstamp() call in tcp_clean_rtx_queue() to later in the loop so
that when a skb is fully acked OPT_STATS of SCM_TSTAMP_ACK will include
the current skb in the delivered count. When not fully acked
tcp_ack_tstamp() is a no-op and there is no change in behavior.

Currently tp->delivered is updated in various places in tcp_ack() but
tp->delivered_ce is updated once at the end. As a result two counts in
OPT_STATS of SCM_TSTAMP_ACK timestamps generated in tcp_ack() may not be
in sync. This patch updates both counts at the same in tcp_ack().

Subject: libbpf: Support disabling auto-loading BPF programs

Currently, bpf_object__load() (and by induction skeleton's load), will always
attempt to prepare, relocate, and load into kernel every single BPF program
found inside the BPF object file. This is often convenient and the right thing
to do and what users expect.

But there are plenty of cases (especially with BPF development constantly
picking up the pace), where BPF application is intended to work with old
kernels, with potentially reduced set of features. But on kernels supporting
extra features, it would like to take a full advantage of them, by employing
extra BPF program. This could be a choice of using fentry/fexit over
kprobe/kretprobe, if kernel is recent enough and is built with BTF. Or BPF
program might be providing optimized bpf_iter-based solution that user-space
might want to use, whenever available. And so on.

With libbpf and BPF CO-RE in particular, it's advantageous to not have to
maintain two separate BPF object files to achieve this. So to enable such use
cases, this patch adds ability to request not auto-loading chosen BPF
programs. In such case, libbpf won't attempt to perform relocations (which
might fail due to old kernel), won't try to resolve BTF types for
BTF-aware (tp_btf/fentry/fexit/etc) program types, because BTF might not be
present, and so on. Skeleton will also automatically skip auto-attachment step
for such not loaded BPF programs.

Overall, this feature allows to simplify development and deployment of
real-world BPF applications with complicated compatibility requirements.

Subject: cail,hsi: fix cfhsi_xmit()'s return type

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.

Fix this by returning 'netdev_tx_t' in this driver too and
returning NETDEV_TX_OK instead of 0 accordingly.

Subject: r8169: sync support for RTL8401 with vendor driver

So far RTL8401 was treated like a RTL8101e, means we relied on the BIOS
to configure MAC and PHY properly. Make RTL8401 a separate chip version
and copy MAC / PHY config from r8101 vendor driver.

The vlan configuration is not restored after interface down/up sequence.

Steps to check:
 # ip link add link eth0 name eth0.100 type vlan id 100
 # ifconfig eth0 down
 # ifconfig eth0 up

This patch fixes it, restoring vlan ALE entries on .ndo_open().

Subject: net: sched: Pass root lock to Qdisc_ops.enqueue

A following patch introduces qevents, points in qdisc algorithm where
packet can be processed by user-defined filters. Should this processing
lead to a situation where a new packet is to be enqueued on the same port,
holding the root lock would lead to deadlocks. To solve the issue, qevent
handler needs to unlock and relock the root lock when necessary.

To that end, add the root lock argument to the qdisc op enqueue, and
propagate throughout.

From 3625750f05ecce21a0fce429c1ff85acfffb461b Mon Sep 17 00:00:00 2001
From: Petr Machata <petrm@mellanox.com>

Subject: net: sched: Introduce helpers for qevent blocks

Qevents are attach points for TC blocks, where filters can be put that are
executed when "interesting events" take place in a qdisc. The data to keep
and the functions to invoke to maintain a qevent will be largely the same
between qevents. Therefore introduce sched-wide helpers for qevent
management.

Currently, similarly to ingress and egress blocks of clsact pseudo-qdisc,
blocks attachment cannot be changed after the qdisc is created. To that
end, add a helper tcf_qevent_validate_change(), which verifies whether
block index attribute is not attached, or if it is, whether its value
matches the current one (i.e. there is no material change).

The function tcf_qevent_handle() should be invoked when qdisc hits the
"interesting event" corresponding to a block. This function releases root
lock for the duration of executing the attached filters, to allow packets
generated through user actions (notably mirred) to be reinserted to the
same qdisc tree.

Subject: net: sched: sch_red: Split init and change callbacks

In the following patches, RED will get two qevents. The implementation will
be clearer if the callback for change is not a pure subset of the callback
for init. Split the two and promote attribute parsing to the callbacks
themselves from the common code, because it will be handy there.

qevents to the RED qdisc: "early_drop" and "mark". Filters attached at
"early_drop" block are executed as packets are early-dropped, those
attached at the "mark" block are executed as packets are ECN-marked.

Two new attributes are introduced: TCA_RED_EARLY_DROP_BLOCK with the block
index for the "early_drop" qevent, and TCA_RED_MARK_BLOCK for the "mark"
qevent. Absence of these attributes signifies "don't care": no block is
allocated in that case, or the existing blocks are left intact in case of
the change callback.

For purposes of offloading, blocks attached to these qevents appear with
newly-introduced binder types, FLOW_BLOCK_BINDER_TYPE_RED_EARLY_DROP and
FLOW_BLOCK_BINDER_TYPE_RED_MARK.

Subject: selftests: forwarding: Add a RED test for SW datapath

This test is inspired by the mlxsw RED selftest. It is much simpler to set
up (also because there is no point in testing PRIO / RED encapsulation). It
tests bare RED, ECN and ECN+nodrop modes of operation. On top of that it
tests RED early_drop and mark qevents.

Subject: net: phy: marvell10g: support XFI rate matching mode

When the hardware MACTYPE hardware configuration pins are set to "XFI
with Rate Matching" the PHY interface operate at fixed 10Gbps speed. The
MAC buffer packets in both directions to match various wire speeds.

Read the MAC Type field in the Port Control register, and set the MAC
interface speed accordingly.

Subject: net: mptcp: improve fallback to TCP

Keep using MPTCP sockets and a use "dummy mapping" in case of fallback
to regular TCP. When fallback is triggered, skip addition of the MPTCP
option on send.

Subject: mptcp: fallback in case of simultaneous connect

when a MPTCP client tries to connect to itself, tcp_finish_connect() is
never reached. Because of this, depending on the socket current state,
multiple faulty behaviours can be observed:

1) a WARN_ON() in subflow_data_ready() is hit
 WARNING: CPU: 2 PID: 882 at net/mptcp/subflow.c:911 subflow_data_ready+0x18b/0x230

2) client is stuck forever in mptcp_sendmsg() because the socket is not
   TCP_ESTABLISHED

3) tcpdump captures show that DSS is exchanged even when MP_CAPABLE handshake
   didn't complete.

force a fallback to TCP in these cases, and adjust the main socket
state to avoid hanging in mptcp_sendmsg().

Subject: mptcp: __mptcp_tcp_fallback() returns a struct sock

Currently __mptcp_tcp_fallback() always return NULL
on incoming connections, because MPTCP does not create
the additional socket for the first subflow.
Since the previous commit no __mptcp_tcp_fallback()
caller needs a struct socket, so let __mptcp_tcp_fallback()
return the first subflow sock and cope correctly even with
incoming connections.

Subject: mptcp: close poll() races

mptcp_poll always return POLLOUT for unblocking
connect(), ensure that the socket is a suitable
state.
The MPTCP_DATA_READY bit is never cleared on accept:
ensure we don't leave mptcp_accept() with an empty
accept queue and such bit set.

Subject: net:qos: police action offloading parameter 'burst' change to the
 original value

Since 'tcfp_burst' with TICK factor, driver side always need to recover
it to the original value, this patch moves the generic calculation and
recover to the 'burst' original value before offloading to device driver.

These rules are per-VNIC, i.e. only apply to the current driver. If a rule matches, then the packet is considered to have the corresponding encapsulation type, and the inner packet is parsed. It is up to the driver to ensure that overlapping rules are not inserted. (If a packet would match multiple rules, a random one of them will be used.) A rule with the exact same match criteria may not be inserted twice (EALREADY). Only a limited number MATCH_FLAGS values are supported, use MC_CMD_GET_PARSER_DISP_INFO with OP OP_GET_SUPPORTED_VNIC_ENCAP_RULE_MATCHES to get a list of supported combinations. Each driver may only have a limited set of active rules - returns ENOSPC if the caller's table is full.

Subject: sfc: determine flag word automatically in efx_has_cap()

Now that we have an _OFST definition for each individual flag bit,
 callers of efx_has_cap() don't need to specify which flag word it's
 in; we can just use the flag name directly in MCDI_CAPABILITY_OFST.

Subject: sfc: refactor EF10 stats handling

Separate the generation-count handling from the format conversion, to
 make it easier to re-use both for EF100.

From 9043f48fd3e302dd3cee49f911ce0fd1494b479f Mon Sep 17 00:00:00 2001
From: Edward Cree <ecree@solarflare.com>

Subject: sfc: split up nic.h

The new nic_common.h contains the inlines for NIC-type function dispatch,
 declarations for NIC-generic functions in nic.c, and other similar NIC-
 generic functionality.  Retained in nic.h are NIC-specific declarations
 such as the siena and ef10 nic_data structs and various farch functions.

The EF100 driver will thus include nic_common.h but not nic.h.

From 4d9c0a2d64551f33638dd566bb82edb3c3cc782c Mon Sep 17 00:00:00 2001
From: Edward Cree <ecree@solarflare.com>

Subject: sfc: extend common GRO interface to support CHECKSUM_COMPLETE

EF100 will use CHECKSUM_COMPLETE, but will also make use of
 efx_rx_packet_gro(), thus needs to be able to pass the checksum value
 into that function.
Drivers for older NICs pass in a csum of 0 to get the old semantics (use
 the RX flags for CHECKSUM_UNNECESSARY marking).

Subject: dpaa2-eth: send a scatter-gather FD instead of realloc-ing

Instead of realloc-ing the skb on the Tx path when the provided headroom
is smaller than the HW requirements, create a Scatter/Gather frame
descriptor with only one entry.

Remove the '[drv] tx realloc frames' counter exposed previously through
ethtool since it is no longer used.

Subject: dpaa2-eth: add software counter for Tx frames converted to S/G

With the previous commit, in case of insufficient SKB headroom on the Tx
path instead of reallocing the SKB we now send a S/G frame descriptor.
Export the number of occurences of this case as a per CPU counter (in
debugfs) and a total number in the ethtool statistics - "tx converted sg
frames'.

Subject: igc: Add initial EEE support

IEEE802.3az-2010 Energy Efficient Ethernet has been
approved as standard (September 2010) and the driver
can enable and disable it via ethtool.
Disable the feature by default on parts which support it.
Add enable/disable eee options.
tx-lpi, tx-timer and advertise not supported yet.

Subject: mlxsw: spectrum_dcb: Rename mlxsw_sp_port_headroom_set()

mlxsw_sp_port_headroom_set() is defined twice - in spectrum.c and in
spectrum_dcb.c, with different arguments and different implementation
but the name is same.

Rename mlxsw_sp_port_headroom_set() to mlxsw_sp_port_headroom_ets_set()
in order to allow using the second function in several files, and not
only as static function in spectrum.c.

+Requests link state information. Link up/down flag (as provided by
+``ETHTOOL_GLINK`` ioctl command) is provided. Optionally, extended state might
+be provided as well. In general, extended state describes reasons for why a port
+is down, or why it operates in some non-obvious mode. This request does not have
+any attributes.

 For most NIC drivers, the value of ``ETHTOOL_A_LINKSTATE_LINK`` returns
 carrier flag provided by ``netif_carrier_ok()`` but there are drivers which
 define their own handler.
 
+``ETHTOOL_A_LINKSTATE_EXT_STATE`` and ``ETHTOOL_A_LINKSTATE_EXT_SUBSTATE`` are
+optional values. ethtool core can provide either both
+``ETHTOOL_A_LINKSTATE_EXT_STATE`` and ``ETHTOOL_A_LINKSTATE_EXT_SUBSTATE``,
+or only ``ETHTOOL_A_LINKSTATE_EXT_STATE``, or none of them.
+
 ``LINKSTATE_GET`` allows dump requests (kernel returns reply messages for all
 devices supporting the request).

From ecc31c60240b9808a274befc5db6b8a249a6ade1 Mon Sep 17 00:00:00 2001

Subject: ethtool: Add link extended state

Currently, drivers can only tell whether the link is up/down using
LINKSTATE_GET, but no additional information is given.

Add attributes to LINKSTATE_GET command in order to allow drivers
to expose the user more information in addition to link state to ease
the debug process, for example, reason for link down state.

Extended state consists of two attributes - link_ext_state and
link_ext_substate. The idea is to avoid 'vendor specific' states in order
to prevent drivers to use specific link_ext_state that can be in the future
common link_ext_state.

The substates allows drivers to add more information to the common
link_ext_state. For example, vendor can expose 'Autoneg' as link_ext_state
and add 'No partner detected during force mode' as link_ext_substate.

If a driver cannot pinpoint the extended state with the substate
accuracy, it is free to expose only the extended state and omit the
substate attribute.

Subject: selftests: forwarding: ethtool: Move different_speeds_get() to
 ethtool_lib

Currently different_speeds_get() is used only by ethtool.sh tests.
The function can be useful for another tests that check ethtool
configurations.

Move the function to ethtool_lib in order to allow other tests to use
it.

Subject: selftests: forwarding: forwarding.config.sample: Add port with no
 cable connected

Add NETIF_NO_CABLE port to tests topology.

The port can also be declared as an environment variable and tests can be
run like that:
NETIF_NO_CABLE=eth9 ./test.sh eth{1..8}

The NETIF_NO_CABLE port will be used by ethtool_extended_state test.

Subject: igc: Clean up Rx timestamping logic

Differently from I210, I225 doesn't report Rx timestamps via the TS bit
Rx descriptor + RXSTMPL/RXSTMPH registers mechanism. Rx timestamps are
reported in the packet buffer only, which is implemented by igc_ptp_rx_
pktstamp(). So this patch removes igc_ptp_rx_rgtstamp() and all code
related to it, copied from igb driver.

Subject: igc: Remove duplicate code in Tx timestamp handling

The functions igc_ptp_tx_hang() and igc_ptp_tx_work() have duplicate
code which handles Tx timestamp timeouts. This patch does a trivial
refactoring by moving that code to its own function and reusing it.

Subject: igc: Check __IGC_PTP_TX_IN_PROGRESS instead of ptp_tx_skb

The __IGC_PTP_TX_IN_PROGRESS flag indicates we have a pending Tx
timestamp. In some places, instead of checking that flag, we check
adapter->ptp_tx_skb. This patch fixes those places to use the flag.

Quick note about igc_ptp_tx_hwtstamp() change: when that function is
called, adapter->ptp_tx_skb is expected to be valid always so we
WARN_ON_ONCE() in case it is not.

Quick note about igc_ptp_suspend() change: when suspending, we don't
really need to check if there is a pending timestamp. We can simply
clear it unconditionally.

Subject: igc: Remove UDP filter setup in PTP code

As implemented in igc_ethtool_get_ts_info(), igc only supports HWTSTAMP_
FILTER_ALL so any HWTSTAMP_FILTER_* option the user may set falls back to
HWTSTAMP_FILTER_ALL.

HWTSTAMP_FILTER_ALL is implemented via Rx Time Sync Control (TSYNCRXCTL)
configuration which timestamps all incoming packets. Configuring a
UDP filter, in addition to TSYNCRXCTL, doesn't add much so this patch
removes that code. It also takes this opportunity to remove some
non-applicable comments.

Subject: igc: Refactor igc_ptp_set_timestamp_mode()

Current igc_ptp_set_timestamp_mode() logic is a bit tangled since it
handles many different hardware configurations in one single place,
making it harder to follow. This patch untangles that code by breaking
it into helper functions.

Quick note about the hw->mac.type check which was removed in this
refactoring: this check it not really needed since igc_i225 is the only
type supported by the IGC driver.

From 1cbedabffdb1737fc40136de9b72e4c69c3e29ce Mon Sep 17 00:00:00 2001
From: Andre Guedes <andre.guedes@intel.com>
Date: Wed, 3 Jun 2020 17:01:05 -0700
Subject: igc: Fix Rx timestamp disabling

When Rx timestamping is enabled, we set the timestamp bit in SRRCTL
register for each queue, but we don't clear it when disabling. This
patch fixes igc_ptp_disable_rx_timestamp() accordingly.

Also, this patch gets rid of igc_ptp_enable_tstamp_rxqueue() and
igc_ptp_enable_tstamp_all_rxqueues() and move their logic into
igc_ptp_enable_rx_timestamp() to keep the enable and disable
helpers symmetric.

Subject: igc: Remove checking media type during MAC initialization

i225 device support only copper mode.
There is no point to check media type in the
igc_config_fc_after_link_up() method.

Subject: netfilter: introduce support for reject at prerouting stage

REJECT statement can be only used in INPUT, FORWARD and OUTPUT
chains. This patch adds support of REJECT, both icmp and tcp
reset, at PREROUTING stage.

The need for this patch comes from the requirement of some
forwarding devices to reject traffic before the natting and
routing decisions.

The main use case is to be able to send a graceful termination
to legitimate clients that, under any circumstances, the NATed
endpoints are not available. This option allows clients to
decide either to perform a reconnection or manage the error in
their side, instead of just dropping the connection and let
them die due to timeout.

It is supported ipv4, ipv6 and inet families for nft
infrastructure.

Subject: netfilter: nft_set_pipapo: Drop useless assignment of scratch  map
 index on insert

In nft_pipapo_insert(), we need to reallocate scratch maps that will
be used for matching by lookup functions, if they have never been
allocated or if the bucket size changes as a result of the insertion.

As pipapo_realloc_scratch() provides a pair of fresh, zeroed out
maps, there's no need to select a particular one after reallocation.

Other than being useless, the existing assignment was also troubled
by the fact that the index was set only on the CPU performing the
actual insertion, as spotted by Florian.

Simply drop the assignment.

Subject: net: dsa: Improve subordinate PHY error message

It is not very informative to know the DSA master device when a
subordinate network device fails to get its PHY setup. Provide the
device name and capitalize PHY while we are it.

Subject: net: dsa/b53: change b53_force_port_config() pause argument

Replace the b53_force_port_config() pause argument, which is based on
phylink's MLO_PAUSE_* definitions, to use a pair of booleans.  This
will allow us to move b53_force_port_config() from
b53_phylink_mac_config() to b53_phylink_mac_link_up().

Subject: net: dsa/bcm_sf2: fix incorrect usage of state->link

state->link has never been valid in mac_config() implementations -
while it may be correct in some calls, it is not true that it can be
relied upon.

Fix bcm_sf2 to use the correct method of handling forced link status.

Refactor it a little as we go, and introduce efx_mcdi_set_mtu() which we
 will later use for ef100 to change MTU without touching other MAC settings.

Subject: sfc: remove duplicate declaration of efx_enqueue_skb_tso()

Define it in nic_common.h, even though the ef100 driver will have a
 different implementation backing it (actually a WARN_ON_ONCE as it
 should never get called by ef100.  But it needs to still exist because
 common TX path code references it).

Subject: net/tls: fix sign extension issue when left shifting u16 value

Left shifting the u16 value promotes it to a int and then it
gets sign extended to a u64.  If len << 16 is greater than 0x7fffffff
then the upper bits get set to 1 because of the implicit sign extension.
Fix this by casting len to u64 before shifting it.

Subject: tcp: call tcp_ack_tstamp() when not fully acked

When skb is coalesced tcp_ack_tstamp() still needs to be called when not
fully acked in tcp_clean_rtx_queue(), otherwise SCM_TSTAMP_ACK
timestamps may never be fired. Since the original patch series had
dependent commits, this patch fixes the issue instead of reverting by
restoring calls to tcp_ack_tstamp() when skb is not fully acked.

Subject: tools/bpftool: Allow substituting custom vmlinux.h for the build

In some build contexts (e.g., Travis CI build for outdated kernel), vmlinux.h,
generated from available kernel, doesn't contain all the types necessary for
BPF program compilation. For such set up, the most maintainable way to deal
with this problem is to keep pre-generated (almost up-to-date) vmlinux.h
checked in and use it for compilation purposes. bpftool after that can deal
with kernel missing some of the features in runtime with no problems.

To that effect, allow to specify path to custom vmlinux.h to bpftool's
Makefile with VMLINUX_H variable.

Subject: selftests/bpf: Allow substituting custom vmlinux.h for selftests
 build

Similarly to bpftool Makefile, allow to specify custom location of vmlinux.h
to be used during the build. This allows simpler testing setups with
checked-in pre-generated vmlinux.h.

Subject: net: ethernet: ixgbe: don't call devm_mdiobus_free()

The idea behind devres is that the release callbacks are called if
probe fails. As we now check the return value of ixgbe_mii_bus_init(),
we can drop the call devm_mdiobus_free() in error path as the release

Date: Mon, 29 Jun 2020 14:03:43 +0200
Subject: net: phy: don't abuse devres in devm_mdiobus_register()

We currently have two managed helpers for mdiobus - devm_mdiobus_alloc()
and devm_mdiobus_register(). The idea behind devres is that the release
callback releases whatever resource the devm function allocates. In the
mdiobus case however there's no devres associated with the device by
devm_mdiobus_register(). Instead the release callback for
devm_mdiobus_alloc(): _devm_mdiobus_free() unregisters the device if
it is marked as managed.

This all seems wrong. The managed structure shouldn't need to know or
care about whether it's managed or not - and this is the case now for
struct mii_bus. The devres wrapper should be opaque to the managed
resource.

This changeset makes devm_mdiobus_alloc() and devm_mdiobus_register()
conform to common devres standards: devm_mdiobus_alloc() allocates a
devres structure and registers a callback that will call mdiobus_free().
__devm_mdiobus_register() allocated another devres and registers a
callback that will unregister the bus.

Subject: of: mdio: provide devm_of_mdiobus_register()

Implement a managed variant of of_mdiobus_register(). We need to make
mdio_devres into its own module because otherwise we'd hit circular
sumbol dependencies between phylib and of_mdio.

Subject: cxgb4: add mirror action to TC-MATCHALL offload

Add mirror Virtual Interface (VI) support to receive all ingress
mirror traffic from the underlying device. The mirror VI is
created dynamically, if the TC-MATCHALL rule has a corresponding
mirror action. Also request MSI-X vectors needed for the mirror VI
Rxqs. If no vectors are available, then disable mirror VI support.

v3:
- Replace mirror VI refcount_t with normal u32 variable.

v2:
- Add mutex to protect all mirror VI data, instead of just
  mirror Rxqs.

From 2b465ed00f7db9c5b2aca95a91671f86282b1822 Mon Sep 17 00:00:00 2001
From: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com>

Subject: cxgb4: add support for mirror Rxqs

When mirror VI is enabled, allocate the mirror Rxqs and setup the
mirror VI RSS table. The mirror Rxqs are allocated/freed when
the mirror VI is created/destroyed or when underlying port is
brought up/down, respectively.

v3:
- Replace mirror VI refcount_t with normal u32 variable.

v2:
- Use mutex to protect all mirror VI data, instead of just
  mirror Rxqs.
- Remove the un-needed mirror Rxq mutex.

Subject: cxgb4: add main VI to mirror VI config replication

When mirror VI is enabled, replicate various VI config params
enabled on main VI to mirror VI. These include replicating MTU,
promiscuous mode, all-multicast mode, and enabled netdev Rx
feature offloads.

v3:
- Replace mirror VI refcount_t with normal u32 variable.
- Add back calling cxgb4_port_mirror_start() in cxgb_open(), which
  was there in v1, but got missed in v2 during refactoring.

v2:
- Simplify the replication code by refactoring t4_set_rxmode()
  to handle mirror VI, instead of duplicating the t4_set_rxmode()
  calls in multiple places.

Subject: libbpf: Make bpf_endian co-exist with vmlinux.h

Make bpf_endian.h compatible with vmlinux.h. It is a frequent request from
users wanting to use bpf_endian.h in their BPF applications using CO-RE and
vmlinux.h.

To achieve that, re-implement byte swap macros and drop all the header
includes. This way it can be used both with linux header includes, as well as
with a vmlinux.h.

Subject: ipvs: avoid expiring many connections from timer

Add new functions ip_vs_conn_del() and ip_vs_conn_del_put()
to release many IPVS connections in process context.
They are suitable for connections found in table
when we do not want to overload the timers.

Currently, the change is useful for the dropentry delayed
work but it will be used also in following patch
when flushing connections to failed destinations.

Date: Mon, 29 Jun 2020 21:33:39 -0700
Subject: bpf: Remove redundant synchronize_rcu.

bpf_free_used_maps() or close(map_fd) will trigger map_free callback.
bpf_free_used_maps() is called after bpf prog is no longer executing:
bpf_prog_put->call_rcu->bpf_prog_free->bpf_free_used_maps.
Hence there is no need to call synchronize_rcu() to protect map elements.

Note that hash_of_maps and array_of_maps update/delete inner maps via
sys_bpf() that calls maybe_wait_bpf_programs() and synchronize_rcu().

Subject: bpf: Introduce helper bpf_get_task_stack()

Introduce helper bpf_get_task_stack(), which dumps stack trace of given
task. This is different to bpf_get_stack(), which gets stack track of
current task. One potential use case of bpf_get_task_stack() is to call
it from bpf_iter__task and dump all /proc/<pid>/stack to a seq_file.

bpf_get_task_stack() uses stack_trace_save_tsk() instead of
get_perf_callchain() for kernel stack. The benefit of this choice is that
stack_trace_save_tsk() doesn't require changes in arch/. The downside of
using stack_trace_save_tsk() is that stack_trace_save_tsk() dumps the
stack trace to unsigned long array. For 32-bit systems, we need to
translate it to u64 array.

Subject: selftests/bpf: Add bpf_iter test with bpf_get_task_stack()

The new test is similar to other bpf_iter tests. It dumps all
/proc/<pid>/stack to a seq_file. Here is some example output:

pid:     2873 num_entries:        3
[<0>] worker_thread+0xc6/0x380
[<0>] kthread+0x135/0x150
[<0>] ret_from_fork+0x22/0x30

pid:     2874 num_entries:        9
[<0>] __bpf_get_stack+0x15e/0x250
[<0>] bpf_prog_22a400774977bb30_dump_task_stack+0x4a/0xb3c

[<0>] do_syscall_64+0x4c/0xa0
[<0>] entry_SYSCALL_64_after_hwframe+0x44/0xa9

Note: bpf_iter test as-is doesn't print the contents of the seq_file. To
see the example above, it is necessary to add printf() to do_dummy_read.

Subject: typhoon: use generic power management

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states. And they use PCI
helper functions to do it.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

In this driver:
typhoon_resume() calls typhoon_wakeup() which then calls PCI helper
functions pci_set_power_state() and pci_restore_state(). The only other
function, using typhoon_wakeup() is typhoon_open().

Thus remove the pci_*() calls from tyhpoon_wakeup() and place them in
typhoon_open(), maintaining the order, to retain the normal behavior of
the function

Now, typhoon_suspend() calls typhoon_sleep() which then calls PCI helper
functions pci_enable_wake(), pci_disable_device() and
pci_set_power_state(). Other functions:
 - typhoon_open()
 - typhoon_close()
 - typhoon_init_one()
are also invoking typhoon_sleep(). Thus, in this case, cannot simply
move PCI helper functions call.

Hence, define a new function typhoon_sleep_early() which will do all the
operations, which typhoon_sleep() was doing before calling PCI helper
functions. Now typhoon_sleep() will call typhoon_sleep_early() to do
those tasks, hence, the behavior for _open(), _close and _init_one() remain
unchanged. And typhon_suspend() only requires typhoon_sleep_early().

Compile-tested only.

Subject: liquidio: use generic power management

Drivers should not use legacy power management as they have to manage power
states and related operations, for the device, themselves. This driver was
handling them with the help of PCI helper functions.

With generic PM, all essentials will be handled by the PCI core. Driver
needs to do only device-specific operations.

The driver defined empty-body .suspend() and .resume() callbacks earlier.
They can now be define NULL and bind with "struct dev_pm_ops" variable.

Compile-tested only.

Subject: sundance: use generic power management

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

Thus, there is no need to call the PCI helper functions like
pci_enable/disable_device(), pci_save/restore_sate() and
pci_set_power_state().

Compile-tested only.

Subject: i40e: Add support for a new feature Total Port Shutdown

After OS requests to down a link on a physical network port, the
traffic is no longer being processed but the physical link with
a link partner is still established.

Currently there is a feature (Link down on close) which allows
to physically bring the link down (after OS request).

With this patch new feature with similar capability is introduced:
TOTAL_PORT_SHUTDOWN
Allows to physically disable the link on the NIC's port.
If enabled, (after link down request from the OS)
no link, traffic or led activity is possible on that port.

If I40E_FLAG_TOTAL_PORT_SHUTDOWN is enabled, the
I40E_FLAG_LINK_DOWN_ON_CLOSE_ENABLED must be explicitly forced to
true and cannot be disabled at that time.
The functionalities are exclusive in terms of configuration, but
they also have similar behavior (allowing to disable physical link
of the port), with following differences:
- LINK_DOWN_ON_CLOSE_ENABLED is configurable at host OS run-time
  and is supported by whole family of 7xx Intel Ethernet Controllers
- TOTAL_PORT_SHUTDOWN may be enabled only before OS loads (in BIOS)
  only if motherboard's BIOS and NIC's FW has support of it
- when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought
  down by sending phy_type=0 to NIC's FW
- when TOTAL_PORT_SHUTDOWN is used, phy_type is not altered, instead
  the link is being brought down by clearing bit
  (I40E_AQ_PHY_ENABLE_LINK) in abilities field of
  i40e_aq_set_phy_config structure

Introduced changes:
- new private flag I40E_FLAG_TOTAL_PORT_SHUTDOWN for handling the
  feature
- probe of NVM if the feature was enabled at driver's port
  initialization
- special handling on link-down procedure to let FW physically
  shutdown the port if the feature was enabled

Subject: i40e: optimize AF_XDP Tx completion path

Improve the performance of the AF_XDP zero-copy Tx completion
path. When there are no XDP buffers being sent using XDP_TX or
XDP_REDIRECT, we do not have go through the SW ring to clean up any
entries since the AF_XDP path does not use these. In these cases, just
fast forward the next-to-use counter and skip going through the SW
ring. The limit on the maximum number of entries to complete is also
removed since the algorithm is now O(1). To simplify the code path, the
maximum number of entries to complete for the XDP path is therefore
also increased from 256 to 512 (the default number of Tx HW
descriptors). This should be fine since the completion in the XDP path
is faster than in the SKB path that has 256 as the maximum number.

This patch provides around 4% throughput improvement for the l2fwd
application in xdpsock on my machine.

Subject: i40e: eliminate division in napi_poll data path

Eliminate a division in the napi_poll data path. This division is
executed even though it is only needed in the rare case when there are
not enough interrupt lines so they have to be shared between queue
pairs. Instead, just test for this case and only execute the division
if needed. The code has been lifted from the ice driver.

Subject: i40e: move check of full Tx ring to outside of send loop

Move the check if the HW Tx ring is full to outside the send
loop. Currently it is checked for every single descriptor that we
send. Instead, tell the send loop to only process a maximum number of
packets equal to the number of available slots in the Tx ring. This
way, we can remove the check inside the send loop to and gain some
performance.

Subject: iavf: Fix updating statistics

Commit bac8486116b0 ("iavf: Refactor the watchdog state machine") inverted
the logic for when to update statistics. Statistics should be updated when
no other commands are pending, instead they were only requested when a
command was processed. iavf_request_stats() would see a pending request
and not request statistics to be updated. This caused statistics to never
be updated; fix the logic.

Subject: ixgbe: Cleanup unneeded delay in ethtool test

There is a 4 seconds delay in ixgbe_diag_test() that is holding up other
ioctls such as SIOCGIFCONF that Oracle database applications use.
One of Oracle's product runs "ethtool -t ethX online" periodically for
system monitoring and that is impacting database applications that use
SIOCGIFCONF at that same time.

This 4 second delay was needed in out early 1GbE parts to give the PHY
time to recover from a reset.  This code was carried forward to the 10 GbE
driver even it was not needed for the supported PHYs in the ixgbe driver.

Subject: selftests/bpf: Switch test_vmlinux to use hrtimer_range_start_ns.

The test_vmlinux test uses hrtimer_nanosleep as hook to test tracing
programs. But in a kernel built by clang, which performs more aggresive
inlining, that function gets inlined into its caller SyS_nanosleep.
Therefore, even though fentry and kprobe do hook on the function,
they aren't triggered by the call to nanosleep in the test.

A possible fix is switching to use a function that is less likely to
be inlined, such as hrtimer_range_start_ns. The EXPORT_SYMBOL functions
shouldn't be inlined based on the description of [1], therefore safe
to use for this test. Also the arguments of this function include the
duration of sleep, therefore suitable for test verification.

[1] af3b56289be1 time: don't inline EXPORT_SYMBOL functions

Tested:
 In a clang build kernel, before this change, the test fails:

 test_vmlinux:PASS:skel_open 0 nsec
 test_vmlinux:PASS:skel_attach 0 nsec
 test_vmlinux:PASS:tp 0 nsec
 test_vmlinux:PASS:raw_tp 0 nsec
 test_vmlinux:PASS:tp_btf 0 nsec
 test_vmlinux:FAIL:kprobe not called
 test_vmlinux:FAIL:fentry not called

 After switching to hrtimer_range_start_ns, the test passes:

 test_vmlinux:PASS:skel_open 0 nsec
 test_vmlinux:PASS:skel_attach 0 nsec
 test_vmlinux:PASS:tp 0 nsec
 test_vmlinux:PASS:raw_tp 0 nsec
 test_vmlinux:PASS:tp_btf 0 nsec
 test_vmlinux:PASS:kprobe 0 nsec
 test_vmlinux:PASS:fentry 0 nsec

When a user selects a non-existing test the summary is printed with

indicated. This can be understood by a human end-user, but for shell
scripting is it useful to indicate a shell failure (EXIT_FAILURE).

Subject: selftests/bpf: Test_progs option for getting number of tests

It can be practial to get the number of tests that test_progs contain.
This could for example be used to create a shell for-loop construct that
runs the individual tests.

Like:
 for N in $(seq 1 $(./test_progs -c)); do
   ./test_progs -n $N 2>&1 > result_test_${N}.log &
 done ; wait

V2: Add the ability to return the count for the selected tests. This is
useful for getting a count e.g. after excluding some tests with option -b.
The current beakers test script like to report the max test count upfront.

Subject: selftests/bpf: Test_progs option for listing test names

The program test_progs have some very useful ability to specify a list of
test name substrings for selecting which tests to run.

This patch add the ability to list the selected test names without running
them. This is practical for seeing which tests gets selected with given
select arguments (which can also contain a exclude list via --name-blacklist).

This output can also be used by shell-scripts in a for-loop:

 for N in $(./test_progs --list -t xdp); do \
   ./test_progs -t $N 2>&1 > result_test_${N}.log & \
 done ; wait

This features can also be used for looking up a test number and returning
a testname. If the selection was empty then a shell EXIT_FAILURE is
returned.  This is useful for scripting. e.g. like this:

 n=1;
 while [ $(./test_progs --list -n $n) ] ; do \
   ./test_progs -n $n ; n=$(( n+1 )); \
 done

Subject: xen: netif.h: add a new extra type for XDP

The patch adds a new extra type to be able to diffirentiate
between RX responses on xen-netfront side with the adjusted offset
required for XDP processing.

The offset value from a guest is passed via xenstore.

Subject: xen networking: add basic XDP support for xen-netfront

The patch adds a basic XDP processing to xen-netfront driver.

We ran an XDP program for an RX response received from netback
driver. Also we request xen-netback to adjust data offset for
bpf_xdp_adjust_head() header space for custom headers.

synchronization between frontend and backend parts is done
by using xenbus state switching:
Reconfiguring -> Reconfigured- > Connected

UDP packets drop rate using xdp program is around 310 kpps
using ./pktgen_sample04_many_flows.sh and 160 kpps without the patch.

Subject: net: ipa: rework ipa_aggr_granularity_val()

The timer used for aggregation makes use of an internal 32 KHz clock.
The granularity of the timer is programmed by a field whose value is
computed by ipa_aggr_granularity_val().  Redefine the way that value
is computed by using a new TIMER_FREQUENCY constant representing the
underlying clock frequency.

Add two BUILD_BUG_ON() calls to ensure the value used is valid.

Subject: net: ipa: reduce aggregation time limit

Halve the time limit used when aggregation is enabled on an RX
endpoint, to half a millisecond.

Use DIV_ROUND_CLOSEST() to compute the value that represents the
time period, to get better accuracy in the event the time limit is
not an even multiple of the granularity.

Subject: net: ipa: always report GSI state errors

We check the state of an event ring or channel both before and after
any GSI command issued that will change that state.  In most--but
not all--cases, if the state is something different than expected we
report an error message.

Add error messages where missing, so that all unexpected states
provide information about what went wrong.  Drop the parentheses
around the state value shown in all cases.

Subject: net: ipa: standarize more GSI error messages

Make minor updates to error messages reported in "gsi.c":
  - Use local variables to reduce multi-line function calls
  - Don't use parentheses in messages
  - Do some slight rewording in a few cases

Subject: net: ipa: kill IPA_MEM_UC_OFFSET

The microcontroller shared memory area is at the beginning of the
IPA resident memory.  IPA_MEM_UC_OFFSET was defined as the offset
within that region where it's found, but it's 0, and it's never
actually used.  Just get rid of the definition, and move some of the
description it had to be above the definition of the ipa_uc_mem_area
structure.

Subject: net: ipa: clarify endpoint register macro constraints

A handful of registers are valid only for RX endpoints, and some
others are valid only for TX endpoints.  For these endpoints, add
a comment above their defined offset macro that indicates the
endpoints to which they apply.

Extend the endpoint parameter naming convention as well, to make
these constraints more explicit.

Subject: net: ipa: HOL_BLOCK_EN_FMASK is a 1-bit mask

The convention throughout the IPA driver is to directly use
single-bit field mask values, rather than using (for example)
u32_encode_bits() to set or clear them.

Fix the one place that doesn't follow that convention, which sets
HOL_BLOCK_EN_FMASK in ipa_endpoint_init_hol_block_enable().

Subject: bonding: allow xfrm offload setup post-module-load

At the moment, bonding xfrm crypto offload can only be set up if the bonding
module is loaded with active-backup mode already set. We need to be able to
make this work with bonds set to AB after the bonding driver has already
been loaded.

So what's done here is:

1) move #define BOND_XFRM_FEATURES to net/bonding.h so it can be used
by both bond_main.c and bond_options.c
2) set BOND_XFRM_FEATURES in bond_dev->hw_features universally, rather than
only when loading in AB mode
3) wire up xfrmdev_ops universally too
4) disable BOND_XFRM_FEATURES in bond_dev->features if not AB
5) exit early (non-AB case) from bond_ipsec_offload_ok, to prevent a
performance hit from traversing into the underlying drivers
5) toggle BOND_XFRM_FEATURES in bond_dev->wanted_features and call
netdev_change_features() from bond_option_mode_set()

In my local testing, I can change bonding modes back and forth on the fly,
have hardware offload work when I'm in AB, and see no performance penalty
to non-AB software encryption, despite having xfrm bits all wired up for
all modes now.

Fixes: 18cb261afd7b ("bonding: support hardware encryption offload to slaves")

From b3c3890489f6d3794916958d1663ab6aecb0290b Mon Sep 17 00:00:00 2001
From: Bruce Allan <bruce.w.allan@intel.com>

Subject: ice: avoid unnecessary single-member variable-length structs

There are a number of structures that consist of a one-element array as the
only struct member.  Some of those are unused so remove them. Others are
used to index into a buffer/array consisting of a variable number of a
different data or structure type.  Those are unnecessary since we can use
simple pointer arithmetic or index directly into the buffer to access
individual elements of the buffer/array.

Additional code cleanups were done near areas affected by this change.

Subject: ice: replace single-element array used for C struct hack

Convert the pre-C90-extension "C struct hack" method (using a single-
element array at the end of a structure for implementing variable-length
types) to the preferred use of C99 flexible array member.

Additional code cleanups were done near areas affected by this change.

Subject: net: sched: Allow changing default qdisc to FQ-PIE

Similar to fq_codel and the other qdiscs that can set as default,
fq_pie is also suitable for general use without explicit configuration,
which makes it a valid choice for this.

This is useful in situations where a painless out-of-the-box solution
for reducing bufferbloat is desired but fq_codel is not necessarily the
best choice. For example, fq_pie can be better for DASH streaming, but
there could be more cases where it's the better choice of the two simple
AQMs available in the kernel.

Subject: selftests: mptcp: add option to specify size of file to transfer

The script generates two random files that are then sent via tcp and
mptcp connections.

In order to compare throughput over consecutive runs add an option
to provide the file size on the command line: "-f 128000".

Also add an option, -t, to enable tcp tests. This is useful to
compare throughput of mptcp connections and tcp connections.

Example: run tests with a 4mb file size, 300ms delay 0.01% loss,
default gso/tso/gro settings and with large write/blocking io:

mptcp_connect.sh -t -f $((4 * 1024 * 1024)) -d 300 -l 0.01%  -r 0 -e "" -m mmap

Subject: mptcp: add receive buffer auto-tuning

When mptcp is used, userspace doesn't read from the tcp (subflow)
socket but from the parent (mptcp) socket receive queue.

skbs are moved from the subflow socket to the mptcp rx queue either from
'data_ready' callback (if mptcp socket can be locked), a work queue, or
the socket receive function.

This means tcp_rcv_space_adjust() is never called and thus no receive
buffer size auto-tuning is done.

An earlier (not merged) patch added tcp_rcv_space_adjust() calls to the
function that moves skbs from subflow to mptcp socket.
While this enabled autotuning, it also meant tuning was done even if
userspace was reading the mptcp socket very slowly.

This adds mptcp_rcv_space_adjust() and calls it after userspace has
read data from the mptcp socket rx queue.

Its very similar to tcp_rcv_space_adjust, with two differences:

1. The rtt estimate is the largest one observed on a subflow
2. The rcvbuf size and window clamp of all subflows is adjusted
   to the mptcp-level rcvbuf.

Otherwise, we get spurious drops at tcp (subflow) socket level if
the skbs are not moved to the mptcp socket fast enough.

Subject: bpf: selftests: A few improvements to network_helpers.c

This patch makes a few changes to the network_helpers.c

1) Enforce SO_RCVTIMEO and SO_SNDTIMEO
   This patch enforces timeout to the network fds through setsockopt
   SO_RCVTIMEO and SO_SNDTIMEO.

   It will remove the need for SOCK_NONBLOCK that requires a more demanding
   timeout logic with epoll/select, e.g. epoll_create, epoll_ctrl, and
   then epoll_wait for timeout.

   That removes the need for connect_wait() from the
   cgroup_skb_sk_lookup.c. The needed change is made in
   cgroup_skb_sk_lookup.c.

2) start_server():
   Add optional addr_str and port to start_server().
   That removes the need of the start_server_with_port().  The caller
   can pass addr_str==NULL and/or port==0.

   I have a future tcp-hdr-opt test that will pass a non-NULL addr_str
   and it is in general useful for other future tests.

   "int timeout_ms" is also added to control the timeout
   on the "accept(listen_fd)".

3) connect_to_fd(): Fully use the server_fd.
   The server sock address has already been obtained from
   getsockname(server_fd).  The sockaddr includes the family,
   so the "int family" arg is redundant.

   Since the server address is obtained from server_fd,  there
   is little reason not to get the server's socket type from the
   server_fd also.  getsockopt(server_fd) can be used to do that,
   so "int type" arg is also removed.

   "int timeout_ms" is added.

4) connect_fd_to_fd():
   "int timeout_ms" is added.
   Some code is also refactored to connect_fd_to_addr() which is
   shared with connect_to_fd().

5) Preserve errno:
   Some callers need to check errno, e.g. cgroup_skb_sk_lookup.c.
   Make changes to do it more consistently in save_errno_close()
   and log_err().

Subject: bpf: selftests: Restore netns after each test

It is common for networking tests creating its netns and making its own
setting under this new netns (e.g. changing tcp sysctl).  If the test
forgot to restore to the original netns, it would affect the
result of other tests.

This patch saves the original netns at the beginning and then restores it
after every test.  Since the restore "setns()" is not expensive, it does it
on all tests without tracking if a test has created a new netns or not.

The new restore_netns() could also be done in test__end_subtest() such
that each subtest will get an automatic netns reset.  However,
the individual test would lose flexibility to have total control
on netns for its own subtests.  In some cases, forcing a test to do
unnecessary netns re-configure for each subtest is time consuming.
e.g. In my vm, forcing netns re-configure on each subtest in sk_assign.c
increased the runtime from 1s to 8s.  On top of that,  test_progs.c
is also doing per-test (instead of per-subtest) cleanup for cgroup.
Thus, this patch also does per-test restore_netns().  The only existing
per-subtest cleanup is reset_affinity() and no test is depending on this.
Thus, it is removed from test__end_subtest() to give a consistent
expectation to the individual tests.  test_progs.c only ensures
any affinity/netns/cgroup change made by an earlier test does not
affect the following tests.

Add MRP attribute IFLA_BRIDGE_MRP_INFO to allow the userspace to get the
current state of the MRP instances. This is a nested attribute that
contains other attributes like, ring id, index of primary and secondary
port, priority, ring state, ring role.

This patch extends the function br_fill_ifinfo to return also the MRP
status for each instance on a bridge. It also adds a new filter
RTEXT_FILTER_MRP to return the MRP status only when this is set, not to
interfer with the vlans. The MRP status is return only on the bridge
interfaces.

Subject: net: ipa: always handle suspend workaround

IPA version 3.5.1 has a hardware quirk that requires special
handling if an RX endpoint is suspended while aggregation is active.
This handling is implemented by ipa_endpoint_suspend_aggr().

Have ipa_endpoint_program_suspend() be responsible for calling
ipa_endpoint_suspend_aggr() if suspend mode is being enabled on
an endpoint.  If the endpoint does not support aggregation, or if
aggregation isn't active, this call will continue to have no effect.

Move the definition of ipa_endpoint_suspend_aggr() up in the file so
its definition precedes the new earlier reference to it.  This
requires ipa_endpoint_aggr_active() and ipa_endpoint_force_close()
to be moved as well.

Subject: net: ipa: simplify ipa_endpoint_program()

Have functions that write endpoint configuration registers return
immediately if they are not valid for the direction of transfer for
the endpoint.  This allows most of the calls in ipa_endpoint_program()
to be made unconditionally.  Reorder the register writes to match
the order of their definition (based on offset).

Subject: sfc: support setting MTU even if not privileged to configure MAC
 fully

Unprivileged functions (such as VFs) may set their MTU by use of the
 'control' field of MC_CMD_SET_MAC_EXT, as used in efx_mcdi_set_mtu().
If calling efx_ef10_mac_reconfigure() from efx_change_mtu(), and the
 NIC supports the above (SET_MAC_ENHANCED capability), use it rather
 than efx_mcdi_set_mac().

Subject: sfc: remove max_interrupt_mode

All NICs supported by this driver are capable of MSI-X interrupts (only
 Falcon A1 wasn't, and that's now hived off into its own driver), so no
 need for a nic-type parameter.  Besides, the code that checked it was
 buggy anyway (the following assignment that checked min_interrupt_mode
 overrode it).

Subject: sfc: move modparam 'interrupt_mode' out of common channel code

EF100 only supports MSI-X, so there's no need for the new driver to
 expose this old module parameter.
Since it's now visible to the linker, we have to rename it internally
 to efx_interrupt_mode to avoid symbol collisions in non-modular
 builds.

Subject: sfc: move modparam 'rss_cpus' out of common channel code

Instead of exposing this old module parameter on the new driver (thus
 having to keep it forever after for compatibility), let's confine it
 to the old one; if we find later that we need the feature, we ought
 to support it properly, with ethtool set-channels.

Subject: sfc: make tx_queues_per_channel variable at runtime

Siena needs four TX queues (csum * highpri), EF10 needs two (csum),
 and EF100 only needs one (as checksumming is controlled entirely by
 the transmit descriptor).  Rather than having various bits of ad-hoc
 code to decide which queues to set up etc., put the knowledge of how
 many TXQs a channel has in one place.

Subject: sfc: assign TXQs without gaps

Since we only allocate VIs for the number of TXQs we actually need, we
 cannot naively use "channel * TXQ_TYPES + txq" for the TXQ number, as
 this has gaps (when efx->tx_queues_per_channel < EFX_TXQ_TYPES) and
 thus overruns the driver's VI allocations, causing the firmware to
 reject the MC_CMD_INIT_TXQ based on INSTANCE.
Thus, we distinguish INSTANCE (stored in tx_queue->queue) from LABEL
 (tx_queue->label); the former is allocated starting from 0 in
 efx_set_channels(), while the latter is simply the txq type (index in
 channel->tx_queue array).
To simplify things, rather than changing tx_queues_per_channel after
 setting up TXQs, make Siena always probe its HIGHPRI queues at start
 of day, rather than deferring it until tc mqprio enables them.

Subject: sfc: get drvinfo driver name from outside the common code

Since ethtool_common.o will be built into both sfc and sfc_ef100 drivers,
 it can't use KBUILD_MODNAME directly.  Instead, make it reference a
 string provided by the individual driver code.

Subject: net/mlx5e: Change reporters create functions to return void

Creation of devlink health reporters is not fatal for mlx5e instance load.
In case of error in reporter's creation, the return value is ignored.
Change all reporters creation functions to return void.

In addition, with this change, a failure in creating a reporter, will not
prevent the driver from trying to create the next reporter in the list.

Subject: net/mlx5e: Remove redundant RQ state query

When received a CQE error, the driver inspect the syndrome given by the
firmware. RQ recovery is initiated only as a result of a fatal syndrome;
syndrome which set the RQ into an error state. Hence no need to query
the RQ state at the beginning of the recovery process. Add additional
debug prints before recovering.

that CQ is a helper to the traffic queues.

After:
$ devlink health diagnose pci/0000:00:0b.0 reporter rx
Common config:
    RQ:
      type: 2 stride size: 2048 size: 8
      CQ:

Subject: net/mlx5e: Enhance TX timeout recovery

Upon a TX timeout handle, if the TX reporter was not able to recover
from the error, reopen the channels. If tried to reopen channels, do not
loop over TX queues for timeout.

With that, the reporters state and separation will better
expose the driver's state.

The GENET driver interfaces with internal MoCA interface as well as
external MoCA chips like the BCM6802/6803 through a fixed link
interface. It is desirable for the mocad user-space daemon to be able to
control the carrier state based upon out of band messages that it
receives from the MoCA chip.

Subject: net: ipa: fix HOLB timer calculation

For IPA v4.2, the exact interpretation of the register that defines
the timeout for avoiding head-of-line blocking was a little unclear.
We're only assigning a 0 timeout to it right now, so that wasn't
very important.  But now that I know how it's supposed to work, I'm
fixing it.

The register represents a tick counter, where each tick is equal to
128 IPA core clock cycles.  For IPA v3.5.1, the register contains
a simple counter value.  But for IPA v4.2, the register contains two
fields, base and scale, which approximate the tick counter as:
    ticks = base << scale
The base and scale values to use for a given tick count are computed
using clever bit operations, and measures are taken to make the
resulting time period as close as possible to that requested.

There's no need for ipa_endpoint_init_hol_block_timer() to return
an error, so change its return type to void.

Add the options --ipv4, --ipv6 to specify running over ipv4 and/or
ipv6. If neither is specified, then run both.

Subject: mvpp2: refactor BM pool init percpu code

In mvpp2_swf_bm_pool_init_percpu(), a reference to a struct
mvpp2_bm_pool is obtained traversing multiple structs, when a
local variable already points to the same object.

Fix it and, while at it, give the variable a meaningful name.

mvpp2_xdp_submit_frame() is a generic function which is called by
mvpp2_xdp_xmit_back() when doing XDP_TX, and by mvpp2_xdp_xmit when
doing AF_XDP or XDP_REDIRECT target.

The buffer allocation has been reworked to be able to map the buffers
as DMA_FROM_DEVICE or DMA_BIDIRECTIONAL depending if native XDP is
in use or not.

Subject: ipvs: allow connection reuse for unconfirmed conntrack
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

YangYuxi is reporting that connection reuse
is causing one-second delay when SYN hits
existing connection in TIME_WAIT state.
Such delay was added to give time to expire
both the IPVS connection and the corresponding
conntrack. This was considered a rare case
at that time but it is causing problem for
some environments such as Kubernetes.

As nf_conntrack_tcp_packet() can decide to
release the conntrack in TIME_WAIT state and
to replace it with a fresh NEW conntrack, we
can use this to allow rescheduling just by
tuning our check: if the conntrack is
confirmed we can not schedule it to different
real server and the one-second delay still
applies but if new conntrack was created,
we are free to select new real server without
any delays.

YangYuxi lists some of the problem reports:

- One second connection delay in masquerading mode:
https://marc.info/?t=151683118100004&r=1&w=2

- IPVS low throughput #70747
https://github.com/kubernetes/kubernetes/issues/70747

- Apache Bench can fill up ipvs service proxy in seconds #544
https://github.com/cloudnativelabs/kube-router/issues/544

- Additional 1s latency in `host -> service IP -> pod`
https://github.com/kubernetes/kubernetes/issues/90854

Fixes: f719e3754ee2 ("ipvs: drop first packet to redirect conntrack")

Subject: netfilter: nf_tables: add NFTA_CHAIN_ID attribute

This netlink attribute allows you to refer to chains inside a
transaction as an alternative to the name and the handle. The chain
binding support requires this new chain ID approach.

Subject: netfilter: nf_tables: add NFT_CHAIN_BINDING

This new chain flag specifies that:

* the kernel dynamically allocates the chain name, if no chain name
  is specified.

* If the immediate expression that refers to this chain is removed,
  then this bound chain (and its content) is destroyed.

Subject: net: use mptcp setsockopt function for SOL_SOCKET on mptcp sockets

setsockopt(mptcp_fd, SOL_SOCKET, ...)...  appears to work (returns 0),
but it has no effect -- this is because the MPTCP layer never has a
chance to copy the settings to the subflow socket.

Skip the generic handling for the mptcp case and instead call the
mptcp specific handler instead for SOL_SOCKET too.

Next patch adds more specific handling for SOL_SOCKET to mptcp.

Subject: mptcp: add REUSEADDR/REUSEPORT support

This will e.g. make 'sshd restart' work when MPTCP is used, as we will
now set this option on the listener socket instead of only the mptcp
socket (where it has no effect).

We still need to copy the setting to the master socket so that a
subsequent getsockopt() returns the expected value.

Subject: mptcp: support IPV6_V6ONLY setsockopt

Without this, Opensshd fails to open an ipv6 socket listening
socket:
  error: setsockopt IPV6_V6ONLY: Operation not supported
  error: Bind to port 22 on :: failed: Address already in use.

Opensshd opens an ipv4 and and ipv6 listening socket, but because
IPV6_V6ONLY setsockopt fails, the port number is already in use.

Subject: net: dsa: microchip: split adjust_link() in
 phylink_mac_link_{up|down}()

The DSA subsystem moved to phylink and adjust_link() became deprecated in
the process. This patch removes adjust_link from the KSZ DSA switches and
adds phylink_mac_link_up() and phylink_mac_link_down().

device's power states and takes care of register states. And they use PCI
helper functions to do it.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

In this driver:
netxen_nic_resume() calls netxen_nic_attach_func() which then invokes PCI
helper functions like pci_enable_device(), pci_set_power_state() and
pci_restore_state(). Other function:
 - netxen_io_slot_reset()
also calls netxen_nic_attach_func().

Also, netxen_io_slot_reset() returns specific value based on the return value
of netxen_nic_attach_func() as whole. Thus, cannot simply move some piece of
code from netxen_nic_attach_func() to it.

Hence, define a new function netxen_nic_attach_late_func() to do the tasks
which has to be done after PCI helper functions have done their job.

Now, netxen_nic_attach_func() invokes netxen_nic_attach_late_func(), thus
netxen_io_slot_reset() behaves normally.
And, netxen_nic_resume() calls netxen_nic_attach_late_func() to avoid PCI
helper functions calls.

Compile-tested only.

Subject: qlcninc: use generic power management

device's power states and taking care of register states. And they use PCI
helper functions to do it.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

.suspend() calls __qlcnic_shutdown, which then calls qlcnic_82xx_shutdown;
.resume()  calls __qlcnic_resume,   which then calls qlcnic_82xx_resume;

Both ...82xx..() are define in
drivers/net/ethernet/qlogic/qlcnic/qlcnic_hw.c and are used only in
drivers/net/ethernet/qlogic/qlcnic/qlcnic_main.c.

Hence upgrade them and remove PCI function calls, like pci_save_state() and
pci_enable_wake(), inside them

Compile-tested only.

Subject: net: dsa: felix: clarify the intention of writes to MII_BMCR

The driver appears to write to BMCR_SPEED and BMCR_DUPLEX, fields which
are read-only, since they are actually configured through the
vendor-specific IF_MODE (0x14) register.

But the reason we're writing back the read-only values of MII_BMCR is to
alter these writable fields:

BMCR_RESET
BMCR_LOOPBACK
BMCR_ANENABLE
BMCR_PDOWN
BMCR_ISOLATE
BMCR_ANRESTART

In particular, the only field which is really relevant to this driver is
BMCR_ANENABLE. Clarify that intention by spelling it out, using
phy_set_bits and phy_clear_bits.

The driver also made a few writes to BMCR_RESET and BMCR_ANRESTART which
are unnecessary and may temporarily disrupt the link to the PHY. Remove
them.

Subject: net: dsa: felix: unconditionally configure MAC speed to 1000Mbps

In VSC9959, the PCS is the one who performs rate adaptation (symbol
duplication) to the speed negotiated by the PHY. The MAC is unaware of
that and must remain configured for gigabit. If it is configured at
OCELOT_SPEED_10 or OCELOT_SPEED_100, it'll start transmitting PAUSE
frames out of control and never recover, _even if_ we then reconfigure
it at OCELOT_SPEED_1000 afterwards.

This patch fixes a bug that luckily did not have any functional impact.
We were writing 10, 100, 1000 etc into this 2-bit field in
DEV_CLOCK_CFG, but the hardware expects values in the range 0, 1, 2, 3.
So all speed values were getting truncated to 0, which is
OCELOT_SPEED_2500, and which also appears to be fine.

Subject: net: dsa: felix: set proper pause frame timers based on link speed

state->speed holds a value of 10, 100, 1000 or 2500, but
SYS_MAC_FC_CFG_FC_LINK_SPEED expects a value in the range 0, 1, 2 or 3.

So set the correct speed encoding into this register.

Subject: net: dsa: felix: delete .phylink_mac_an_restart code

Phylink uses the .mac_an_restart method to offer the user an
implementation of the "ethtool -r" behavior, when the media-side auto
negotiation can be restarted by the local MAC PCS. This is the case for
fiber modes 1000Base-X and 2500Base-X (IEEE clause 37) that don't have
an Ethernet PHY connected locally, and the media is connected to the MAC
PCS directly.

On the other hand, the Cisco SGMII and USXGMII standards also have an
auto negotiation mechanism based on IEEE 802.3 clause 37 (their
respective specs require a MAC PCS and a PHY PCS to implement the same
state machine, which is described in IEEE 802.3 "Auto-Negotiation Figure
37-6"), so the ability to restart auto-negotiation is intrinsically
symmetrical (the MAC PCS can do it too).

However, it appears that not all SGMII/USXGMII PHYs have logic to
restart the MDI-side auto-negotiation process when they detect a
transition of the SGMII link from data mode to configuration mode.
Some do (VSC8234) and some don't (AR8033, MV88E1111). IEEE and/or Cisco
specification wordings to not help to prove whether propagating the "AN
restart" event from MII side ("mr_restart_an") to MDI side
("mr_restart_negotiation") is required behavior - neither of them
specifies any mandatory interaction between the clause 37 AN state
machine from Figure 37-6 and the clause 28 AN state machine from Figure
28-18.

Therefore, even if a certain behavior could be proven as being required,
real-life SGMII/USXGMII PHYs are inconsistent enough that a clause 37 AN
restart cannot be used by phylink to reliably trigger a media-side
renegotiation, when the user requests it via ethtool.

The only remaining use that the .mac_an_restart callback might possibly
have, given what we know now, is to implement some silicon quirks, but
so far that has proven to not be necessary.

So remove this code for now, since it never gets called and we don't
foresee any circumstance in which it might be, either.

Subject: net: dsa: felix: use resolved link config in mac_link_up()

Phylink now requires that parameters established through
auto-negotiation be written into the MAC at the time of the
mac_link_up() callback. In the case of felix, that means taking the port
out of reset, setting the correct timers for PAUSE frames, and
enabling/disabling TX flow control.

This patch also splits the inband and noinband configuration of the
vsc9959 PCS (currently found in a function called "init") into 2
different functions, which have a nomenclature closer to phylink:
"config", for inband setup, and "link_up", for noinband (forced) setup.

This is necessary as a preparation step for giving up control of the PCS
to phylink, which will be done in further patch series.

Oddly, GENMASK() requires signed bit numbers, so that it can compare
them for < 0. If passed an unsigned type, we get warnings about the
test never being true.

Subject: sun/sungem: use generic power management

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states. And they use PCI
helper functions to do it.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

In this driver:
gem_suspend() calls gem_do_stop() which in turn invokes
pci_disable_device(). As the PCI helper function is not called at the
end/start of the function body, breaking the function in two parts
may change its behavior.

The only other function invoking gem_do_stop() is gem_close(). Hence,
gem_close() and gem_suspend() can do the required end steps on their own.

The same case is with gem_resume(). Both gem_resume() and gem_open()
invoke gem_do_start(). Again, make the caller functions do the required
steps on their own.

Compile-tested only.

Subject: sun/niu: use generic power management

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

The driver was calling pci_save/restore_state() which is no more needed.

Compile-tested only.

Subject: selftests: mptcp: capture pcap on both sides

When investigating performance issues that involve latency / loss /
reordering it is useful to have the pcap from the sender-side as it
allows to easier infer the state of the sender's congestion-control,
loss-recovery, etc.

Allow the selftests to capture a pcap on both sender and receiver so
that this information is not lost when reproducing.

This patch also improves the file names. Instead of:

  ns4-5ee79a56-X4O6gS-ns3-5ee79a56-X4O6gS-MPTCP-MPTCP-10.0.3.1.pcap

We now have something like for the same test:

  5ee79a56-X4O6gS-ns3-ns4-MPTCP-MPTCP-10.0.3.1-10030-connector.pcap
  5ee79a56-X4O6gS-ns3-ns4-MPTCP-MPTCP-10.0.3.1-10030-listener.pcap

It was a connection from ns3 to ns4, better to start with ns3 then. The
port is also added, easier to find the trace we want.

Subject: geneve: move all configuration under struct geneve_config

This patch adds a new structure geneve_config and moves the per-device
configuration attributes to it, like we already have in VXLAN with
struct vxlan_config. This ends up being pretty invasive since those
attributes are used everywhere.

This allows us to clean up the argument lists for geneve_configure (4
arguments instead of 8) and geneve_nl2info (5 instead of 9).

This also reduces the copy-paste of code setting those attributes
between geneve_configure and geneve_changelink to a single memcpy,
which would have avoided the bug fixed in commit
56c09de347e4 ("geneve: allow changing DF behavior after creation").

Subject: net: qed: move static iro_arr[] out of header file

Static variables (and functions, unless they're inline) should not
be declared in header files.
Move the static array iro_arr[] from "qed_hsi.h" to the sole place
where it's used, "qed_init_ops.c". This eliminates lots of warnings
(42 of them actually) against W=1+:

In file included from drivers/net/ethernet/qlogic/qed/qed.h:51:0,
                 from drivers/net/ethernet/qlogic/qed/qed_ooo.c:40:
drivers/net/ethernet/qlogic/qed/qed_hsi.h:4421:18: warning: 'iro_arr'
defined but not used [-Wunused-const-variable=]
 static const u32 iro_arr[] = {

Subject: net: qed: cleanup global structs declarations

Fix several sparse warnings by moving structs declarations into
the corresponding header files:

drivers/net/ethernet/qlogic/qed/qed_dcbx.c:2402:32: warning:
symbol 'qed_dcbnl_ops_pass' was not declared. Should it be static?

drivers/net/ethernet/qlogic/qed/qed_ll2.c:2754:26: warning: symbol
'qed_ll2_ops_pass' was not declared. Should it be static?

drivers/net/ethernet/qlogic/qed/qed_ptp.c:449:30: warning: symbol
'qed_ptp_ops_pass' was not declared. Should it be static?

drivers/net/ethernet/qlogic/qed/qed_sriov.c:5265:29: warning:
symbol 'qed_iov_ops_pass' was not declared. Should it be static?

(some of them were declared twice in different header files)

Also make qed_hw_err_type_descr[] const while at it.

Subject: net: qed: correct qed_hw_err_notify() prototype
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change the prototype of qed_hw_err_notify() with the following:
* constify "fmt" argument according to printk() declarations;
* anontate it with __cold attribute to move the function out of
  the line;
* annotate it with __printf() attribute;

This eliminates W=1+ warning:

drivers/net/ethernet/qlogic/qed/qed_hw.c: In function
‘qed_hw_err_notify’:
drivers/net/ethernet/qlogic/qed/qed_hw.c:851:3: warning: function
‘qed_hw_err_notify’ might be a candidate for ‘gnu_printf’ format
attribute [-Wsuggest-attribute=format]
 len = vsnprintf(buf, QED_HW_ERR_MAX_STR_SIZE, fmt, vl);
 ^~~

as well as saves some code size:

add/remove: 0/0 grow/shrink: 2/4 up/down: 40/-125 (-85)

Total: Before=368645, After=368560, chg -0.02%

__printf() will also be helpful with catching bad format strings
and arguments.

Subject: net: qed: address kernel-doc warnings

Get rid of the kernel-doc warnings when building with W=1+ by
rewriting the problematic doc comments according to the
recommended format and style.

Note that this only fixes problems found in C source files,
headers aren't in scope for now.

Subject: net: qed: use ptr shortcuts to dedup field accessing in some parts

Use intermediate pointers instead of multiple dereferencing to
simplify and beautify parts of code that will be addressed in
the next commit.

From 5ab903418ad14732131df0af0d63f19b73e377ae Mon Sep 17 00:00:00 2001
From: Alexander Lobakin <alobakin@marvell.com>
Date: Mon, 6 Jul 2020 18:38:19 +0300
Subject: net: qed: sanitize BE/LE data processing

Current code assumes that both host and device operates in Little Endian
in lots of places. While this is true for x86 platform, this doesn't mean
we should not care about this.

This commit addresses all parts of the code that were pointed out by sparse
checker. All operations with restricted (__be*/__le*) types are now
protected with explicit from/to CPU conversions, even if they're noops on
common setups.

I'm sure there are more such places, but this implies a deeper code
investigation, and is a subject for future works.

Subject: Replace HTTP links with HTTPS ones: IPv*

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

Subject: mptcp: fix race in subflow_data_ready()

syzkaller was able to make the kernel reach subflow_data_ready() for a
server subflow that was closed before subflow_finish_connect() completed.
In these cases we can avoid using the path for regular/fallback MPTCP
data, and just wake the main socket, to avoid the following warning:

Subject: dt-bindings: net: bluetooth: realtek: Fix uart-has-rtscts example

uart-has-rtscts is a boolean property. These are defined as present
(which means that this property evaluates to "true") or absent (which
means that this property evaluates to "false"). Remove the numeric value
from the example to make it comply with the boolean property bindings.

Subject: Bluetooth: Fix kernel oops triggered by hci_adv_monitors_clear()

This fixes the kernel oops by removing unnecessary background scan
update from hci_adv_monitors_clear() which shouldn't invoke any work
queue.

The following test was performed.
- Run "rmmod btusb" and verify that no kernel oops is triggered.

Subject: ice: add documentation for device-caps region

The recent change by commit 8d7aab3515fa ("ice: implement snapshot for
device capabilities") to implement the device-caps region for the ice
driver forgot to document it.

Add documentation to the ice devlink documentation file describing the
new region and add some sample output to the shell commands provided as
an example.

Subject: net: sfp: Unique GPIO interrupt names

Dynamically generate a unique GPIO interrupt name, based on the
device name and the GPIO name.  For example:

103:          0   sx1503q  12 Edge      sff2-los
104:          0   sx1503q  13 Edge      sff2-tx-fault

The sffX indicates the SFP the los and tx-fault are associated with.

v3:
- reverse Christmas tree new variable
- fix spaces vs tabs
v2:
- added net-next to PATCH part of subject line
- switched to devm_kasprintf()

Subject: net: phy: at803x: Avoid comparison is always false warning

By placing the GENMASK value into an unsigned int and then passing it
to PREF_FIELD, the type is reduces down from ULL. Given the reduced
size of the type, the range checks in PREP_FAIL() are always true, and
-Wtype-limits then gives a warning.

By skipping the intermediate variable, the warning can be avoided.

Subject: net: phy: cavium: Improve __iomem mess

The MIPS low level register access functions seem to be missing
__iomem annotation. This causes lots of sparse warnings, when code
casts off the __iomem. Make the Cavium MDIO drivers cleaner by pushing
the casts lower down into the helpers, allow the drivers to work as
normal, with __iomem.

bus->register_base is now an void *, rather than a u64. So forming the
mii_bus->id string cannot use %llx any more. Use %px, so this kernel
address is still exposed to user space, as it was before.

Subject: net: phy: mdio-octeon: Cleanup module loading dependencies

To ensure that the octeon MDIO driver has been loaded, the Cavium
ethernet drivers reference a dummy symbol in the MDIO driver. This
forces it to be loaded first. And this symbol has not been cleanly
implemented, resulting in warnings when build W=1 C=1.

Since device tree is being used, and a phandle points to the PHY on
the MDIO bus, we can make use of deferred probing. If the PHY fails to
connect, it should be because the MDIO bus driver has not loaded
yet. Return -EPROBE_DEFER so it will be tried again later.

Additionally, add a MODULE_SOFTDEP() to give user space a hint as to
what order it should load the modules.

s/octoen/octeon/
Add MODULE_SOFTDEP()

Subject: mptcp: use mptcp worker for path management

We can re-use the existing work queue to handle path management
instead of a dedicated work queue.  Just move pm_worker to protocol.c,
call it from the mptcp worker and get rid of the msk lock (already held).

Subject: mvpp2: fix pointer check

priv->page_pool is an array, so comparing against it will always return true.
Do a meaningful check by checking priv->page_pool[0] instead.
While at it, clear the page_pool pointers on deallocation, or when an
allocation error happens during init.

Subject: epic100: use generic power management

Drivers should not use legacy power management as they have to manage power
states and related operations, for the device, themselves.

With generic PM, all essentials will be handled by the PCI core. Driver
needs to do only device-specific operations.

Compile-tested only.

Subject: net: phy: add a Kconfig option for mdio_devres

If phylib is built as a module and CONFIG_MDIO_DEVICE is 'y', the
mdio_device and mdio_bus code will be in the phylib module, not in the
kernel image. Meanwhile we build mdio_devres depending on the
CONFIG_MDIO_DEVICE symbol, so if it's 'y', it will go into the kernel
and we'll hit the following linker error:

   ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_alloc_size':
>> drivers/net/phy/mdio_devres.c:38: undefined reference to `mdiobus_alloc_size'
   ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_free':
>> drivers/net/phy/mdio_devres.c:16: undefined reference to `mdiobus_free'
   ld: drivers/net/phy/mdio_devres.o: in function `__devm_mdiobus_register':
>> drivers/net/phy/mdio_devres.c:87: undefined reference to `__mdiobus_register'
   ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_unregister':

>> drivers/net/phy/mdio_devres.c:120: undefined reference to `of_mdiobus_register'

Add a hidden Kconfig option for MDIO_DEVRES which will be currently
selected by CONFIG_PHYLIB as there are no non-phylib users of these
helpers.

In order to decouple ethtool from its PHY library dependency, define an
ethtool_phy_ops singleton which can be overriden by the PHY library when
it loads with an appropriate set of function pointers.

Subject: bpf: Add BPF_CGROUP_INET_SOCK_RELEASE hook

Sometimes it's handy to know when the socket gets freed. In
particular, we'd like to try to use a smarter allocation of
ports for bpf_bind and explore the possibility of limiting
the number of SOCK_DGRAM sockets the process can have.

Implement BPF_CGROUP_INET_SOCK_RELEASE hook that triggers on
inet socket release. It triggers only for userspace sockets
(not in-kernel ones) and therefore has the same semantics as
the existing BPF_CGROUP_INET_SOCK_CREATE.

Subject: samples: bpf: Fix bpf programs with kprobe/sys_connect event

Currently, BPF programs with kprobe/sys_connect does not work properly.

Commit 34745aed515c ("samples/bpf: fix kprobe attachment issue on x64")
This commit modifies the bpf_load behavior of kprobe events in the x64
architecture. If the current kprobe event target starts with "sys_*",
add the prefix "__x64_" to the front of the event.

Appending "__x64_" prefix with kprobe/sys_* event was appropriate as a
solution to most of the problems caused by the commit below.

    commit d5a00528b58c ("syscalls/core, syscalls/x86: Rename struct
    pt_regs-based sys_*() to __x64_sys_*()")

However, there is a problem with the sys_connect kprobe event that does
not work properly. For __sys_connect event, parameters can be fetched
normally, but for __x64_sys_connect, parameters cannot be fetched.

    ffffffff818d3520 <__x64_sys_connect>:
    ffffffff818d3520: e8 fb df 32 00        callq   0xffffffff81c01520
    <__fentry__>
    ffffffff818d3525: 48 8b 57 60           movq    96(%rdi), %rdx
    ffffffff818d3529: 48 8b 77 68           movq    104(%rdi), %rsi
    ffffffff818d352d: 48 8b 7f 70           movq    112(%rdi), %rdi
    ffffffff818d3531: e8 1a ff ff ff        callq   0xffffffff818d3450
    <__sys_connect>
    ffffffff818d3536: 48 98                 cltq
    ffffffff818d3538: c3                    retq
    ffffffff818d3539: 0f 1f 80 00 00 00 00  nopl    (%rax)

As the assembly code for __x64_sys_connect shows, parameters should be
fetched and set into rdi, rsi, rdx registers prior to calling
__sys_connect.

Because of this problem, this commit fixes the sys_connect event by
first getting the value of the rdi register and then the value of the
rdi, rsi, and rdx register through an offset based on that value.

Subject: samples: bpf: Refactor BPF map in map test with libbpf

From commit 646f02ffdd49 ("libbpf: Add BTF-defined map-in-map
support"), a way to define internal map in BTF-defined map has been
added.

Instead of using previous 'inner_map_idx' definition, the structure to
be used for the inner map can be directly defined using array directive.

    __array(values, struct inner_map)

This commit refactors map in map test program with libbpf by explicitly
defining inner map with BTF-defined format.

Subject: samples: bpf: Refactor BPF map performance test with libbpf

Previously, in order to set the numa_node attribute at the time of map
creation using "libbpf", it was necessary to call bpf_create_map_node()
directly (bpf_load approach), instead of calling bpf_object_load()
that handles everything on its own, including map creation. And because
of this problem, this sample had problems with refactoring from bpf_load
to libbbpf.

However, by commit 1bdb6c9a1c43 ("libbpf: Add a bunch of attribute
getters/setters for map definitions") added the numa_node attribute and
allowed it to be set in the map.

By using libbpf instead of bpf_load, the inner map definition has
been explicitly declared with BTF-defined format. Also, the element of
ARRAY_OF_MAPS was also statically specified using the BTF format. And
for this reason some logic in fixup_map() was not needed and changed
or removed.

Subject: selftests: bpf: Remove unused bpf_map_def_legacy struct

samples/bpf no longer use bpf_map_def_legacy and instead use the
libbpf's bpf_map_def or new BTF-defined MAP format. This commit removes
unused bpf_map_def_legacy struct from selftests/bpf/bpf_legacy.h.

Subject: Bluetooth: Use whitelist for scan policy when suspending

Even with one advertisement monitor in place, the scan policy should use
the whitelist while the system is going to suspend to prevent waking by
random advertisement.

The following test was performed.
- With a paired device, register one advertisement monitor, suspend
the system and verify that the host was not awaken by random
advertisements.

Subject: net: dsa: loop: Print when registration is successful

We have a number of error conditions that can lead to the driver not
probing successfully, move the print when we are sure
dsa_register_switch() has suceeded. This avoids repeated prints in case
of probe deferral for instance.

Subject: Replace HTTP links with HTTPS ones: ATMEL MACB ETHERNET DRIVER

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:

Subject: net: phy: Define PHY statistics ethtool_phy_ops

Extend ethtool_phy_ops to include the 3 function pointers necessary for
implementing PHY statistics. In a subsequent change we will uninline
those functions.

Subject: net: phy: Uninline PHY ethtool statistics operations

Now that we have moved the PHY ethtool statistics to be dynamically
registered, we no longer need to inline those for ethtool. This used to
be done to avoid cross symbol referencing and allow ethtool to be
decoupled from PHYLIB entirely.

Subject: bnxt_en: Set up the chip specific RSS table size.

Currently, we allocate one page for the hardware DMA RSS indirection
table.  While the size is currently big enough for all chips, future
chip variations may support bigger sizes, so it is better to calculate
and store the chip specific size and allocate accordingly.

Subject: bnxt_en: Add logical RSS indirection table structure.

The driver currently does not keep track of the logical RSS indirection
table.  The hardware RSS table is set up with standard default ring
distribution when initializing the chip.  This makes it difficult to
support user sepcified indirection table entries.  As a first step, add
the logical table in the main bnxt structure and allocate it according
to chip specific table size.  Add a function that sets up default
RSS distribution based on the number of RX rings.

v4: Use bnxt_get_rxfh_indir_size() for the current RSS table size.

v2: Use kmalloc_array() since we init. all entries afterwards.
    Use ALIGN() to roundup the RSS table size.
    Use ethtool_rxfh_indir_default() to init. the default entries.

Subject: bnxt_en: Add helper function to return the number of RSS contexts.

On some chips, this varies based on the number of RX rings.  Add this
helper function and refactor the existing code to use it.

Subject: bnxt_en: Fill HW RSS table from the RSS logical indirection table.

Now that we have the logical table, we can fill the HW RSS table
using the logical table's entries and converting them to the HW
specific format.  Re-initialize the logical table to standard
distribution if the number of RX rings changes during ring reservation.

v4: Use bnxt_get_rxfh_indir_size() to get the RSS table size.

v2: Use ALIGN() to roundup the RSS table size.

Subject: bnxt_en: Implement ethtool -X to set indirection table.

With the new infrastructure in place, we can now support the setting of
the indirection table from ethtool.

When changing channels, in a rare case that firmware cannot reserve the
rings that were promised, we will still try to keep the RSS map and only
revert to default when absolutely necessary.

v4: Revert RSS map to default during ring change only when absolutely
    necessary.

v3: Add warning messages when firmware cannot reserve the requested RX
    rings, and when the RSS table entries have to change to default.

v2: When changing channels, if the RSS table size changes and RSS map
    is non-default, return error.

Subject: bnxt_en: clean up VLAN feature bit handling

The hardware VLAN offload feature on our NIC does not have separate
knobs for handling customer and service tags on RX. Either offloading
of both must be enabled or both must be disabled. Introduce definitions
for the combined feature set in order to clean up the code and make
this constraint more clear. Technically these features can be separately
enabled on TX, however, since the default is to turn both on, the
combined TX feature set is also introduced for code consistency.

Subject: bnxt_en: allow firmware to disable VLAN offloads

Bare-metal use cases require giving firmware and the embedded
application processor control over VLAN offloads. The driver should
not attempt to override or utilize this feature in such scenarios
since it will not work as expected.

Subject: ethtool: Add support for 100Gbps per lane link modes

Define 100G, 200G and 400G link modes using 100Gbps per lane

LR, ER and FR are defined as a single link mode because they are
using same technology and by design are fully interoperable.
EEPROM content indicates if the module is LR, ER, or FR, and the
user space ethtool decoder is planned to support decoding these
modes in the EEPROM.

emit_obj_refs_json needs to added the same as with emit_obj_refs_plain
to prevent segfaults, similar to Commit "8ae4121bd89e bpf: Fix bpftool
without skeleton code enabled"). See the error below:

    # ./bpftool -p prog

Subject: selftests/bpf: test_progs use another shell exit on non-actions

This is a follow up adjustment to commit 6c92bd5cd465 ("selftests/bpf:
Test_progs indicate to shell on non-actions"), that returns shell exit
indication EXIT_FAILURE (value 1) when user selects a non-existing test.

The problem with using EXIT_FAILURE is that a shell script cannot tell
the difference between a non-existing test and the test failing.

This patch uses value 2 as shell exit indication.
(Aside note unrecognized option parameters use value 64).

Subject: selftests/bpf: test_progs avoid minus shell exit codes

There are a number of places in test_progs that use minus-1 as the argument
to exit(). This is confusing as a process exit status is masked to be a
number between 0 and 255 as defined in man exit(3). Thus, users will see
status 255 instead of minus-1.

This patch use positive exit code 3 instead of minus-1. These cases are put
in the same group of infrastructure setup errors.

Subject: net: dsa: tag_rtl4_a: Implement Realtek 4 byte A tag

This implements the known parts of the Realtek 4 byte
tag protocol version 0xA, as found in the RTL8366RB
DSA switch.

It is designated as protocol version 0xA as a
different Realtek 4 byte tag format with protocol
version 0x9 is known to exist in the Realtek RTL8306
chips.

The tag and switch chip lacks public documentation, so
the tag format has been reverse-engineered from
packet dumps. As only ingress traffic has been available
for analysis an egress tag has not been possible to
develop (even using educated guesses about bit fields)
so this is as far as it gets. It is not known if the
switch even supports egress tagging.

Excessive attempts to figure out the egress tag format
was made. When nothing else worked, I just tried all bit
combinations with 0xannp where a is protocol and p is
port. I looped through all values several times trying
to get a response from ping, without any positive
result.

Using just these ingress tags however, the switch
functionality is vastly improved and the packets find
their way into the destination port without any
tricky VLAN configuration. On the D-Link DIR-685 the
LAN ports now come up and respond to ping without
any command line configuration so this is a real
improvement for users.

Egress packets need to be restricted to the proper
target ports using VLAN, which the RTL8366RB DSA
switch driver already sets up.

Subject: net: dsa: rtl8366rb: Support the CPU DSA tag

This activates the support to use the CPU tag to properly
direct ingress traffic to the right port.

Bit 15 in register RTL8368RB_CPU_CTRL_REG can be set to
1 to disable the insertion of the CPU tag which is what
the code currently does. The bit 15 define calls this
setting RTL8368RB_CPU_INSTAG which is confusing since the
inverse meaning is implied: programmers may think that
setting this bit to 1 will *enable* inserting the tag
rather than disabling it, so rename this setting in
bit 15 to RTL8368RB_CPU_NO_TAG which is more to the
point.

After this e.g. ping works out-of-the-box with the
RTL8366RB.

Subject: bonding: deal with xfrm state in all modes and add more
 error-checking

It's possible that device removal happens when the bond is in non-AB mode,
and addition happens in AB mode, so bond_ipsec_del_sa() never gets called,
which leaves security associations in an odd state if bond_ipsec_add_sa()
then gets called after switching the bond into AB. Just call add and
delete universally for all modes to keep things consistent.

However, it's also possible that this code gets called when the system is
shutting down, and the xfrm subsystem has already been disconnected from
the bond device, so we need to do some error-checking and bail, lest we
hit a null ptr deref.

makes CO-RE relocation more reliable, as they are not going to be just
silently skipped, if BTF finalization failed.

Subject: libbpf: Add btf__set_fd() for more control over loaded BTF FD

Add setter for BTF FD to allow application more fine-grained control in more
advanced scenarios. Storing BTF FD inside `struct btf` provides little benefit
and probably would be better done differently (e.g., btf__load() could just
return FD on success), but we are stuck with this due to backwards
compatibility. The main problem is that it's impossible to load BTF and than
free user-space memory, but keep FD intact, because `struct btf` assumes
ownership of that FD upon successful load and will attempt to close it during
btf__free(). To allow callers (e.g., libbpf itself for BTF sanitization) to
have more control over this, add btf__set_fd() to allow to reset FD
arbitrarily, if necessary.

Subject: libbpf: Improve BTF sanitization handling

Change sanitization process to preserve original BTF, which might be used by
libbpf itself for Kconfig externs, CO-RE relocs, etc, even if kernel is old
and doesn't support BTF. To achieve that, if libbpf detects the need for BTF
sanitization, it would clone original BTF, sanitize it in-place, attempt to
load it into kernel, and if successful, will preserve loaded BTF FD in
original `struct btf`, while freeing sanitized local copy.

If kernel doesn't support any BTF, original btf and btf_ext will still be
preserved to be used later for CO-RE relocation and other BTF-dependent libbpf
features, which don't dependon kernel BTF support.

Patch takes care to not specify BTF and BTF.ext features when loading BPF
programs and/or maps, if it was detected that kernel doesn't support BTF
features.

Subject: selftests/bpf: Add test relying only on CO-RE and no recent kernel
 features

Add a test that relies on CO-RE, but doesn't expect any of the recent
features, not available on old kernels. This is useful for Travis CI tests
running against very old kernels (e.g., libbpf has 4.9 kernel testing now), to
verify that CO-RE still works, even if kernel itself doesn't support BTF yet,
as long as there is .BTF embedded into vmlinux image by pahole. Given most of
CO-RE doesn't require any kernel awareness of BTF, it is a useful test to
validate that libbpf's BTF sanitization is working well even with ancient
kernels.

Subject: libbpf: Handle missing BPF_OBJ_GET_INFO_BY_FD gracefully in
 perf_buffer

perf_buffer__new() is relying on BPF_OBJ_GET_INFO_BY_FD availability for few
sanity checks. OBJ_GET_INFO for maps is actually much more recent feature than
perf_buffer support itself, so this causes unnecessary problems on old kernels
before BPF_OBJ_GET_INFO_BY_FD was added.

This patch makes those sanity checks optional and just assumes best if command
is not supported. If user specified something incorrectly (e.g., wrong map
type), kernel will reject it later anyway, except user won't get a nice
explanation as to why it failed. This seems like a good trade off for
supporting perf_buffer on old kernels.

Subject: selftests/bpf: Switch perf_buffer test to tracepoint and skeleton

Switch perf_buffer test to use skeleton to avoid use of bpf_prog_load() and
make test a bit more succinct. Also switch BPF program to use tracepoint
instead of kprobe, as that allows to support older kernels, which had
tracepoint support before kprobe support in the form that libbpf expects
(i.e., libbpf expects /sys/bus/event_source/devices/kprobe/type, which doesn't
always exist on old kernels).

Subject: bonding: don't need RTNL for ipsec helpers

The bond_ipsec_* helpers don't need RTNL, and can potentially get called
without it being held, so switch from rtnl_dereference() to
rcu_dereference() to access bond struct data.

Lightly tested with xfrm bonding, no problems found, should address the
syzkaller bug referenced below.

Subject: xfrm: add is_ipip to struct xfrm_input_afinfo

This patch is to add a new member is_ipip to struct xfrm_input_afinfo,
to allow another group family of callback functions to be registered
with is_ipip set.

This will be used for doing a callback for struct xfrm(6)_tunnel of
ipip/ipv6 tunnels in xfrm_input() by calling xfrm_rcv_cb(), which is
needed by ipip/ipv6 tunnels' support in ip(6)_vti and xfrm interface
in the next patches.

Subject: tunnel4: add cb_handler to struct xfrm_tunnel

This patch is to register a callback function tunnel4_rcv_cb with
is_ipip set in a xfrm_input_afinfo object for tunnel4 and tunnel64.

It will be called by xfrm_rcv_cb() from xfrm_input() when family
is AF_INET and proto is IPPROTO_IPIP or IPPROTO_IPV6.

v1->v2:
  - Fix a sparse warning caused by the missing "__rcu", as Jakub
    noticed.
  - Handle the err returned by xfrm_input_register_afinfo() in
    tunnel4_init/fini(), as Sabrina noticed.
v2->v3:
  - Add "#if IS_ENABLED(CONFIG_INET_XFRM_TUNNEL)" to fix the build error
    when xfrm is disabled, reported by kbuild test robot.

Subject: ip_vti: support IPIP tunnel processing with .cb_handler

With tunnel4_input_afinfo added, IPIP tunnel processing in
ip_vti can be easily done with .cb_handler. So replace the
processing by calling ip_tunnel_rcv() with it.

v1->v2:
  - no change.
v2-v3:
  - enable it only when CONFIG_INET_XFRM_TUNNEL is defined, to fix
    the build error, reported by kbuild test robot.

Subject: ip6_vti: support IP6IP6 tunnel processing with .cb_handler

Similar to IPIP tunnel's processing, this patch is to support
IP6IP6 tunnel processing with .cb_handler.

v1->v2:
  - no change.
v2-v3:
  - enable it only when CONFIG_INET6_XFRM_TUNNEL is defined, to fix
    the build error, reported by kbuild test robot.

For IP6IP tunnel processing, the functions called will be the
same as that for IP6IP6 tunnel's. So reuse it and register it
with family == AF_INET.

Subject: inet_diag: support for wider protocol numbers

After commit bf9765145b85 ("sock: Make sk_protocol a 16-bit value")
the current size of 'sdiag_protocol' is not sufficient to represent
the possible protocol values.

This change introduces a new inet diag request attribute to let
user space specify the relevant protocol number using u32 values.

The attribute is parsed by inet diag core on get/dump command
and the extended protocol value, if available, is preferred to
'sdiag_protocol' to lookup the diag handler.

The parse attributed are exposed to all the diag handlers via
the cb->data.

Note that inet_diag_dump_one_icsk() is left unmodified, as it
will not be used by protocol using the extended attribute.

Subject: mptcp: add msk interations helper

mptcp_token_iter_next() allow traversing all the MPTCP
sockets inside the token container belonging to the given
network namespace with a quite standard iterator semantic.

That will be used by the next patch, but keep the API generic,
as we plan to use this later for PM's sake.

Additionally export mptcp_token_get_sock(), as it also
will be used by the diag module.

Subject: net: systemport: fix double shift of a vlan_tci by VLAN_PRIO_SHIFT

Currently the u16 skb->vlan_tci is being right  shifted twice by
VLAN_PRIO_SHIFT, once in the macro skb_vlan_tag_get_pri and explicitly
by VLAN_PRIO_SHIFT afterwards. The combined shift amount is larger than
the u16 so the end result is always zero.  Remove the second explicit
shift as this is extraneous.

Fixes: 6e9fdb60d362 ("net: systemport: Add support for VLAN transmit acceleration")
Addresses-Coverity: ("Operands don't affect result")

The struct devlink_port_attrs holds the attributes of devlink_port.

The 'set' field is not devlink_port's attribute as opposed to most of the
others.

Move 'set' to be devlink_port's field called 'attrs_set'.

The struct devlink_port_attrs holds the attributes of devlink_port.

Similarly to the previous patch, 'switch_port' attribute is another
exception.

Move 'switch_port' to be devlink_port's field.

Currently, devlink_port_attrs_set accepts a long list of parameters,
that most of them are devlink port's attributes.

Use the devlink_port_attrs struct to replace the relevant parameters.

From 622d3e9201072aaa94d6291b8dee05e3dd50c3af Mon Sep 17 00:00:00 2001
From: Danielle Ratson <danieller@mellanox.com>
Date: Thu, 9 Jul 2020 16:18:17 +0300
Subject: mlxsw: Set number of port lanes attribute in driver

Currently, port attributes like flavour, port number and whether the
port was split are set when initializing a port.

Set the number of lanes of the port as well so that it could be easily
passed to devlink in the next patch.

Subject: devlink: Add a new devlink port lanes attribute and pass to netlink

Add a new devlink port attribute that indicates the port's number of lanes.

Drivers are expected to set it via devlink_port_attrs_set(), before
registering the port.

The attribute is not passed to user space in case the number of lanes is
invalid (0).

Subject: mlxsw: Set port split ability attribute in driver

Currently, port attributes like flavour, port number and whether the port
was split are set when initializing a port.

Set the split ability of the port as well, based on port_mapping->width
field and split attribute of devlink port in spectrum, so that it could be
easily passed to devlink in the next patch.

Subject: selftests: net: Add port split test

Test port split configuration using previously added number of port lanes
attribute.

Check that all the splittable ports are successfully split to their maximum
number of lanes and below, and that those which are not splittable fail to
be split.

Test output example:

TEST: swp4 is unsplittable                                         [ OK ]
TEST: split port swp53 into 4                                      [ OK ]
TEST: Unsplit port pci/0000:03:00.0/25                             [ OK ]
TEST: split port swp53 into 2                                      [ OK ]
TEST: Unsplit port pci/0000:03:00.0/25                             [ OK ]

Subject: net/mlx5: E-switch, When eswitch is unsupported, return -EOPNOTSUPP

When eswitch is unsupported, currently -EPERM error code is returned
instead of -EOPNOTSUPP.

Due to this VF device's devlink virtual port is not enumerated because
port_function_get() callback returned -EPERM instead of -EOPNOTSUPP.

Hence, return the error code -EOPNOTSUPP when eswitch is unsupported.

Subject: net/mlx5e: CT: Allow header rewrite of 5-tuple and ct clear action

With ct clear we don't jump to the ct tables, so header rewrite
of 5-tuple can be done in place (and not moved to after the CT action).

Check for ct clear action, and if so, allow 5-tuple header
rewrite.

The next patch will pass the mlx5e_priv struct to the
modify_header_match_supported method. Use this opportunity to refactor
the existing pr_info call to a netdev_info call.

Subject: net/mlx5e: CT: Don't offload tuple rewrites for established tuples

Next patches will remove the tupleid registers that is used
to restore the ct state on miss, and instead use the tuple on
the missed packet to lookup which state to restore.
Disable tuple rewrites after connection tracking.

For tuple rewrites, inject a ct_state=-trk match so it won't
change the tuple for established flows (+trk) that passed connection
tracking, and instead miss to software.

Subject: net/mlx5e: CT: Restore ct state from lookup in zone instead of
 tupleid

Remove tupleid, and replace it with zone_restore, which is the zone an
established tuple sets after match. On miss, Use this zone + tuple
taken from the skb, to lookup the ct entry and restore it.

This improves flow insertion rate by avoiding the allocation of a header
rewrite context.

Subject: net/mlx5e: Export sharing of mod headers to a new file

Refactor sharing of mod headers to new file and while there,
remove spin lock and flows list, as this is only used for warn on.

Use the generic API in the next patch to re-use tuple modify headers
for identical modify actions,

Subject: net/mlx5e: CT: Re-use tuple modify headers for identical modify
 actions

After removing the tupleid register which changed per tuple,
tuple modify headers set the ct_state, zone, mark, and label registers.
For non-natted tuples going through the same tc rules path, their values
will be the same, and all their modify headers will be the same.

Re-use tuple modify header when possible, by adding each new modify
header to an hahstable, and looking up identical ones before creating
a new one.

Subject: net/mlx5e: CT: Use mapping for zone restore register

Use a single byte mapping for zone restore register (zone matching
remains 16 bit).

This makes room for using the freed 8 bits on register C1 for
mapping more tunnels and tunnel options.

Subject: net/mlx5e: CT: Expand tunnel register mappings

Reg_c1 is 32 bits wide. Originally, 24 bit were allocated for the tuple_id,
6 bits for tunnel mapping and 2 bits for tunnel options mappings.

Restoring the ct state from zone lookup instead of tuple id requires
reg_c1 to store 8 bits mapping the ct zone, leaving 24 bits for tunnel
mappings.

Expand tunnel and tunnel options register mappings to 12 bit each.

Subject: net/mlx5e: CT: Return err_ptr from internal functions

Instead of having to deal with converting between int and ERR_PTR for
return values in mlx5_tc_ct_flow_offload(), make the internal helper
functions return a ptr to mlx5_flow_handle instead of passing it as
output param, this will also avoid gcc confusion and false alarms,
thus we remove the redundant ERR_PTR rule initialization.

Subject: libbpf: Fix memory leak and optimize BTF sanitization

Coverity's static analysis helpfully reported a memory leak introduced by
0f0e55d8247c ("libbpf: Improve BTF sanitization handling"). While fixing it,
I realized that btf__new() already creates a memory copy, so there is no need
to do this. So this patch also fixes misleading btf__new() signature to make
data into a `const void *` input parameter. And it avoids unnecessary memory
allocation and copy in BTF sanitization code altogether.

Subject: Bluetooth: Fix slab-out-of-bounds read in
 hci_extended_inquiry_result_evt()

Check upon `num_rsp` is insufficient. A malformed event packet with a
large `num_rsp` number makes hci_extended_inquiry_result_evt() go out
of bounds. Fix it.

This patch fixes the following syzbot bug:

Subject: Replace HTTP links with HTTPS ones: BLUETOOTH SUBSYSTEM

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Subject: debugfs: make sure we can remove u32_array files cleanly

debugfs_create_u32_array() allocates a small structure to wrap
the data and size information about the array. If users ever
try to remove the file this leads to a leak since nothing ever
frees this wrapper.

That said there are no upstream users of debugfs_create_u32_array()
that'd remove a u32 array file (we only have one u32 array user in
CMA), so there is no real bug here.

Make callers pass a wrapper they allocated. This way the lifetime
management of the wrapper is on the caller, and we can avoid the
potential leak in debugfs.

There doesn't appear to be any user using the type as an

Subject: udp_tunnel: add central NIC RX port offload infrastructure

Cater to devices which:
 (a) may want to sleep in the callbacks;
 (b) only have IPv4 support;
 (c) need all the programming to happen while the netdev is up.

Drivers attach UDP tunnel offload info struct to their netdevs,
where they declare how many UDP ports of various tunnel types
they support. Core takes care of tracking which ports to offload.

Use a fixed-size array since this matches what almost all drivers
do, and avoids a complexity and uncertainty around memory allocations
in an atomic context.

Make sure that tunnel drivers don't try to replay the ports when
new NIC netdev is registered. Automatic replays would mess up
reference counting, and will be removed completely once all drivers
are converted.

v4:
 - use a #define NULL to avoid build issues with CONFIG_INET=n.

From c7d759eb7b12f91a25f4d3cd03ff5209046ddfc2 Mon Sep 17 00:00:00 2001
From: Jakub Kicinski <kuba@kernel.org>
Date: Thu, 9 Jul 2020 17:42:47 -0700
Subject: ethtool: add tunnel info interface

Add an interface to report offloaded UDP ports via ethtool netlink.

Now that core takes care of tracking which UDP tunnel ports the NICs
are aware of we can quite easily export this information out to
user space.

The responsibility of writing the netlink dumps is split between
ethtool code and udp_tunnel_nic.c - since udp_tunnel module may
not always be loaded, yet we should always report the capabilities
of the NIC.

$ ethtool --show-tunnels eth0
Tunnel information for eth0:
  UDP port table 0:
    Size: 4
    Types: vxlan
    No entries
  UDP port table 1:
    Size: 4
    Types: geneve, vxlan-gpe
    Entries (1):
        port 1230, vxlan-gpe

v4:
 - back to v2, build fix is now directly in udp_tunnel.h
v3:
 - don't compile ETHTOOL_MSG_TUNNEL_INFO_GET in if CONFIG_INET
   not set.
v2:
 - fix string set count,
 - reorder enums in the uAPI,
 - fix type of ETHTOOL_A_TUNNEL_UDP_TABLE_TYPES to bitset
   in docs and comments.

Subject: ixgbe: don't clear UDP tunnel ports when RXCSUM is disabled

It appears the clearing of UDP tunnel ports when RXCSUM
is disabled is unnecessary. Driver will not pay attention
to checksum bits if RXCSUM is not set, so we can let
the hardware parse the packets.

Note that the UDP tunnel port NDO handlers don't pay attention
to the state of RXCSUM, so the ports could had been re-programmed,
anyway.

This cleanup simplifies later conversion patch.

v2:
 - break this out of the following patch.

Subject: ixgbe: convert to new udp_tunnel_nic infra

Make use of new common udp_tunnel_nic infra. ixgbe supports
IPv4 only, and only single VxLAN and Geneve ports (one each).

v2:
 - split out the RXCSUM feature handling to separate change;
 - declare structs separately;
 - use ti.type instead of assuming table 0 is VxLAN;
 - move setting netdev->udp_tunnel_nic_info to its own switch.

Subject: devlink: Rework devlink health reporter destructor

Devlink keeps its own reference to every reporter in a list and inits
refcount to 1 upon reporter's creation. Existing destructor waits to
free the memory indefinitely using msleep() until all references except
devlink's own are put.

Rework this mechanism by moving memory free routine to a separate
function, which is called when the last reporter reference is put.

Besides, it allows to call __devlink_health_reporter_destroy() while
locked on a reporters list mutex in symmetry to
__devlink_health_reporter_create(), which is required in follow-up
patch.

Subject: devlink: Implement devlink health reporters on per-port basis

Add devlink-health reporter support on per-port basis.
The main difference existing devlink-health is that port reporters are
stored in per-devlink_port lists. Upon creation of such health reporter the
reference to a port it belongs to is stored in reporter struct.

Fill the port index attribute in devlink-health response to
allow devlink userspace utility to distinguish between device and port
reporters.

Subject: net/mlx5e: Move devlink port register and unregister calls

Register devlink ports upon NIC init. TX and RX health reporters handle
errors which may occur early on at driver initialization. And because
these reporters are to be moved to port context, they require devlink
ports to be already registered.

Subject: inet: Remove an unnecessary argument of syn_ack_recalc().

Commit 0c3d79bce48034018e840468ac5a642894a521a3 ("tcp: reduce SYN-ACK
retrans for TCP_DEFER_ACCEPT") introduces syn_ack_recalc() which decides
if a minisock is held and a SYN+ACK is retransmitted or not.

If rskq_defer_accept is not zero in syn_ack_recalc(), max_retries always
has the same value because max_retries is overwritten by rskq_defer_accept
in reqsk_timer_handler().

This commit adds three changes:
- remove redundant non-zero check for rskq_defer_accept in
   reqsk_timer_handler().
- remove max_retries from the arguments of syn_ack_recalc() and use
   rskq_defer_accept instead.
- rename thresh to max_syn_ack_retries for readability.

Subject: net: bridge: notify on vlan tunnel changes done via the old api

If someone uses the old vlan API to configure tunnel mappings we'll only
generate the old-style full port notification. That would be a problem
if we are monitoring the new vlan notifications for changes. The patch
resolves the issue by adding vlan notifications to the old tunnel netlink
code. As usual we try to compress the notifications for as many vlans
in a range as possible, thus a vlan tunnel change is considered able
to enter the "current" vlan notification range if:
 1. vlan exists
 2. it has actually changed (curr_change == true)
 3. it passes all standard vlan notification range checks done by
    br_vlan_can_enter_range() such as option equality, id continuity etc

Note that vlan tunnel changes (add/del) are considered a part of vlan
options so only RTM_NEWVLAN notification is generated with the relevant
information inside.

Subject: net: fec: Set max MTU size to allow the MTU to be changed

The FEC allocates 2K buffers, but looses some of it due to
alignment. It can however support an MTU bigger than the default. This
is particularly interesting when used in combination with Ethernet
switches supporting DSA, which have extra headers. The DSA core will
try to increase the MTU to support these extra headers. If the max
size defaults to that of standard Ethernet we get a warning. By
setting the max to what the driver actually supports, we avoid this
warning.

Subject: net: skge: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GPF_ with a correct flag.
It has been compile tested.

When memory is allocated in 'skge_up()', GFP_KERNEL can be used because
some other memory allocations done a few lines below in 'skge_ring_alloc()'
already use this flag.

xfrmi_lookup() is called on every packet. Using a single list for
looking up if_id becomes a bottleneck when having many xfrm interfaces.

Subject: Bluetooth: hci_qca: Bug fixes for SSR

1.During SSR for command time out if BT SoC goes to inresponsive
state, power cycling of BT SoC was not happening. Given the fix by
sending hw error event to reset the BT SoC.

2.If SSR is triggered then ignore the transmit data requests to
BT SoC until SSR is completed.

From fbbb68de80a45ad66b66600bee275485c5073aa7 Mon Sep 17 00:00:00 2001

Subject: bpf: Add resolve_btfids tool to resolve BTF IDs in ELF object

The resolve_btfids tool scans elf object for .BTF_ids section
and resolves its symbols with BTF ID values.

It will be used to during linking time to resolve arrays of BTF
ID values used in verifier, so these IDs do not need to be
resolved in runtime.

The expected layout of .BTF_ids section is described in main.c
header. Related kernel changes are coming in following changes.

Build issue reported by 0-DAY CI Kernel Test Service.

Subject: bpf: Add BTF_ID_LIST/BTF_ID/BTF_ID_UNUSED macros

Adding support to generate .BTF_ids section that will hold BTF
ID lists for verifier.

Adding macros that will help to define lists of BTF ID values
placed in .BTF_ids section. They are initially filled with zeros
(during compilation) and resolved later during the linking phase
by resolve_btfids tool.

Following defines list of one BTF ID value:

  BTF_ID_LIST(bpf_skb_output_btf_ids)
  BTF_ID(struct, sk_buff)

It also defines following variable to access the list:

  extern u32 bpf_skb_output_btf_ids[];

The BTF_ID_UNUSED macro defines 4 zero bytes. It's used when we
want to define 'unused' entry in BTF_ID_LIST, like:

  BTF_ID_LIST(bpf_skb_output_btf_ids)
  BTF_ID(struct, sk_buff)
  BTF_ID_UNUSED
  BTF_ID(struct, task_struct)

Using BTF_ID_LIST macro to define lists for several helpers
using BTF arguments.

And running resolve_btfids on vmlinux elf object during linking,
so the .BTF_ids section gets the IDs resolved.

Subject: bpf: Remove btf_id helpers resolving

Now when we moved the helpers btf_id arrays into .BTF_ids section,
we can remove the code that resolve those IDs in runtime.

+4.2 .BTF_ids section
+====================
+
+The .BTF_ids section encodes BTF ID values that are used within the kernel.
+
+This section is created during the kernel compilation with the help of
+macros defined in ``include/linux/btf_ids.h`` header file. Kernel code can
+use them to create lists and sets (sorted lists) of BTF ID values.
+
+The ``BTF_ID_LIST`` and ``BTF_ID`` macros define unsorted list of BTF ID values,
+with following syntax::
+
+  BTF_ID_LIST(list)
+  BTF_ID(type1, name1)
+  BTF_ID(type2, name2)
+
+resulting in following layout in .BTF_ids section::
+
+  __BTF_ID__type1__name1__1:
+  .zero 4
+  __BTF_ID__type2__name2__2:
+  .zero 4
+
+The ``u32 list[];`` variable is defined to access the list.
+
+The ``BTF_ID_UNUSED`` macro defines 4 zero bytes. It's used when we
+want to define unused entry in BTF_ID_LIST, like::
+
+      BTF_ID_LIST(bpf_skb_output_btf_ids)
+      BTF_ID(struct, sk_buff)
+      BTF_ID_UNUSED
+      BTF_ID(struct, task_struct)
+
+All the BTF ID lists and sets are compiled in the .BTF_ids section and
+resolved during the linking phase of kernel build by ``resolve_btfids`` tool.

Subject: tools headers: Adopt verbatim copy of btf_ids.h from kernel sources

It will be needed by bpf selftest for resolve_btfids tool.

Also adding __PASTE macro as btf_ids.h dependency, which is
defined in:

  include/linux/compiler_types.h

but because tools/include do not have this header, I'm putting
the macro into linux/compiler.h header.

Subject: selftests/bpf: Add test for resolve_btfids

Adding resolve_btfids test under test_progs suite.

It's possible to use btf_ids.h header and its logic in
user space application, so we can add easy test for it.

The test defines BTF_ID_LIST and checks it gets properly
resolved.

For this reason the test_progs binary (and other binaries
that use TRUNNER* macros) is processed with resolve_btfids
tool, which resolves BTF IDs in .BTF_ids section. The BTF
data are taken from btf_data.o object rceated from
progs/btf_data.c.

Subject: net: bridge: fix undefined br_vlan_can_enter_range in tunnel code

If bridge vlan filtering is not defined we won't have
br_vlan_can_enter_range and thus will get a compile error as was
reported by Stephen and the build bot. So let's define a stub for when
vlan filtering is not used.

Fixes: 94339443686b ("net: bridge: notify on vlan tunnel changes done via the old api")

Subject: net: fddi: skfp: Remove addr_to_string().

kbuild test robot found that addr_to_string() is available only when
DEBUG is defined. And I found that what that function is doing is
what %pM will do. Thus, replace %s with %pM and remove thread-unsafe
addr_to_string() function.

Subject: xsk: Add new statistics

It can be useful for the user to know the reason behind a dropped packet.
Introduce new counters which track drops on the receive path caused by:
1. rx ring being full
2. fill ring being empty

Also, on the tx path introduce a counter which tracks the number of times
we attempt pull from the tx ring when it is empty.

Subject: samples: bpf: Add an option for printing extra statistics in xdpsock

Introduce the --extra-stats (or simply -x) flag to the xdpsock application
which prints additional statistics alongside the regular rx and tx
counters. The new statistics printed report error conditions eg. rx ring
full, invalid descriptors, etc.

Subject: bpf: Use dedicated bpf_trace_printk event instead of trace_printk()

The bpf helper bpf_trace_printk() uses trace_printk() under the hood.
This leads to an alarming warning message originating from trace
buffer allocation which occurs the first time a program using
bpf_trace_printk() is loaded.

We can instead create a trace event for bpf_trace_printk() and enable
it in-kernel when/if we encounter a program using the
bpf_trace_printk() helper.  With this approach, trace_printk()
is not used directly and no warning message appears.

This work was started by Steven (see Link) and finished by Alan; added
Steven's Signed-off-by with his permission.

Subject: libbpf: Support stripping modifiers for btf_dump

One important use case when emitting const/volatile/restrict is undesirable is
BPF skeleton generation of DATASEC layout. These are further memory-mapped and
can be written/read from user-space directly.

For important case of .rodata variables, bpftool strips away first-level
modifiers, to make their use on user-space side simple and not requiring extra
type casts to override compiler complaining about writing to const variables.

This logic works mostly fine, but breaks in some more complicated cases. E.g.:

    const volatile int params[10];

Because in BTF it's a chain of ARRAY -> CONST -> VOLATILE -> INT, bpftool
stops at ARRAY and doesn't strip CONST and VOLATILE. In skeleton this variable
will be emitted as is. So when used from user-space, compiler will complain
about writing to const array. This is problematic, as also mentioned in [0].

To solve this for arrays and other non-trivial cases (e.g., inner
const/volatile fields inside the struct), teach btf_dump to strip away any
modifier, when requested. This is done as an extra option on
btf_dump__emit_type_decl() API.

Subject: tools/bpftool: Strip away modifiers from global variables

Reliably remove all the type modifiers from read-only (.rodata) global
variable definitions, including cases of inner field const modifiers and
arrays of const values.

Also modify one of selftests to ensure that const volatile struct doesn't
prevent user-space from modifying .rodata variable.

Fixes: 985ead416df3 ("bpftool: Add skeleton codegen command")

Subject: net: ipa: fix kerneldoc comments

This commit affects comments (and in one case, whitespace) only.

Throughout the IPA code, return statements are documented using
"@Return:", whereas they should use "Return:" instead.  Fix these
mistakes.

In function definitions, some parameters are missing their comment
to describe them.  And in structure definitions, some fields are
missing their comment to describe them.  Add these missing
descriptions.

Some arguments changed name and type along the way, but their
descriptions were not updated (an endpoint pointer is now used in
many places that previously used an endpoint ID).  Fix these
incorrect parameter descriptions.

In the description for the ipa_clock structure, one field had a
semicolon instead of a colon in its description.  Fix this.

Add a missing function description for ipa_gsi_endpoint_data_empty().

All of these issues were identified when building with "W=1".

Subject: net: sched: Pass qdisc reference in struct flow_block_offload

Previously, shared blocks were only relevant for the pseudo-qdiscs ingress
and clsact. Recently, a qevent facility was introduced, which allows to
bind blocks to well-defined slots of a qdisc instance. RED in particular
got two qevents: early_drop and mark. Drivers that wish to offload these
blocks will be sent the usual notification, and need to know which qdisc it
is related to.

To that end, extend flow_block_offload with a "sch" pointer, and initialize
as appropriate. This prompts changes in the indirect block facility, which
now tracks the scheduler in addition to the netdevice. Update signatures of
several functions similarly.

Subject: mlxsw: spectrum_span: Move SPAN operations out of global file

The per-ASIC SPAN operations are relevant to the SPAN module and
therefore should be implemented there and not in the main driver file.
Move them.

These operations will be extended later on.

Subject: mlxsw: spectrum_span: Prepare for global mirroring triggers

Currently, a SPAN agent can only be bound to a per-port trigger where
the trigger is either an incoming packet (INGRESS) or an outgoing packet
(EGRESS) to / from the port.

The subsequent patch will introduce the concept of global mirroring
triggers. The binding / unbinding of global triggers is different than
that of per-port triggers. Such triggers also need to be enabled /
disabled on a per-{port, TC} basis and are only supported from
Spectrum-2 onwards.

Add trigger operations that allow us to abstract these differences. Only
implement the operations for per-port triggers. Next patch will
implement the operations for global triggers.

Subject: mlxsw: spectrum_span: Add support for global mirroring triggers

Global mirroring triggers are triggers that are only keyed by their
trigger, as opposed to per-port triggers, which are keyed by their
trigger and port.

Such triggers allow mirroring packets that were tail/early dropped or
ECN marked to a SPAN agent.

Implement the previously added trigger operations for these global
triggers. Since such triggers are only supported from Spectrum-2
onwards, have the Spectrum-1 operations return an error.

Subject: mlxsw: spectrum_span: Add APIs to enable / disable global mirroring
 triggers

While the binding of global mirroring triggers to a SPAN agent is
global, packets are only mirrored if they belong to a port and TC on
which the trigger was enabled. This allows, for example, to mirror
packets that were tail-dropped on a specific netdev.

Implement the operations that allow to enable / disable a global
mirroring trigger on a specific port and TC.

Subject: mlxsw: spectrum_matchall: Publish matchall data structures

A following patch introduces offloading of filters attached to blocks bound
to the RED tail_drop qevent. The only classifier that mlxsw will permit in
this role is matchall. mlxsw currently offloads matchall filters used with
clsact qdisc. The data structures used for that offload will come handy for
the qevent offload as well. Publish them in spectrum.h.

Subject: mlxsw: spectrum_flow: Promote binder-type dispatch to spectrum.c

Two RED qevents have been introduced recently. From the point of view of a
driver, qevents are simply blocks with unusual binder types. However they
need to be handled by different logic than ACL-like flows.

Thus rename mlxsw_sp_setup_tc_block() to mlxsw_sp_setup_tc_block_clsact()
and move the binder-type dispatch from there to spectrum.c into a new
function of the original name. The new dispatcher is easier to extend with
new binder types.

Subject: mlxsw: spectrum_qdisc: Offload mirroring on RED qevent early_drop

The RED qevents early_drop and mark can be offloaded under the following
fairly strict conditions:

- At most one filter is configured at the qevent block
- The protocol is "any"
- The classifier is matchall
- The action is trap, sample, or mirror with the same conditions as
  with other SPAN offloads
- The hw_counters type is none

In this patchset, implement offload of mirror for early_drop qevent.
The ECN trigger is currently not implemented in the FW and therefore
the mark qevent is not supported.

The qevent notifications look exactly like regular block binding
notifications with a binder type that identifies them as qevents.
Therefore the details of processing this binding are fairly similar
to the matchall offload.

struct flow_block_offload.sch points at the qdisc in question. Use it to
figure out if the qdisc is offloaded at all and what TC it configures.
Bounce bindings on not-offloaded qdiscs.

Individual bindings are kept in a list so that several qevents can share
the same block and all binding points get configured as the configured
filters change.

Subject: net: make symbol 'flush_works' static

The sparse tool complains as follows:

net/core/dev.c:5594:1: warning:
 symbol '__pcpu_scope_flush_works' was not declared. Should it be static?

'flush_works' is not used outside of dev.c, so marks
it static.

Subject: isdn/capi: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Subject: devlink: Fix use-after-free when destroying health reporters

Dereferencing the reporter after it was destroyed in order to unlock the
reporters lock results in a use-after-free [1].

Fix this by storing a pointer to the lock in a local variable before
destroying the reporter.

Subject: net: mscc: ocelot: convert port registers to regmap

At the moment, there are some minimal register differences between
VSC7514 Ocelot and VSC9959 Felix. To be precise, the PCS1G registers are
missing from Felix because it was integrated with an NXP PCS.

But with VSC9953 Seville (not yet introduced), the register differences
are more pronounced.  The MAC registers are located at different offsets
within the DEV_GMII target. So we need to refactor the driver to keep a
regmap even for per-port registers. The callers of the ocelot_port_readl
and ocelot_port_writel were kept unchanged, only the implementation is
now more generic.

Subject: soc: mscc: ocelot: add MII registers description

Add the register definitions for the MSCC MIIM MDIO controller in
preparation for seville_vsc9959.c to create its accessors for the
internal MDIO bus.

Since we've introduced elements to ocelot_regfields that are not
instantiated by felix and ocelot, we need to define the size of the
regfields arrays explicitly, otherwise ocelot_regfields_init, which
iterates up to REGFIELD_MAX, will fault on the undefined regfield
entries (if we're lucky).

Subject: net: mscc: ocelot: convert QSYS_SWITCH_PORT_MODE and SYS_PORT_MODE to
 regfields

Currently Felix and Ocelot share the same bit layout in these per-port
registers, but Seville does not. So we need reg_fields for that.

Actually since these are per-port registers, we need to also specify the
number of ports, and register size per port, and use the regmap API for
multiple ports.

There's a more subtle point to be made about the other 2 register
fields:
- QSYS_SWITCH_PORT_MODE_SCH_NEXT_CFG
- QSYS_SWITCH_PORT_MODE_INGRESS_DROP_MODE
which we are not writing any longer, for 2 reasons:
- Using the previous API (ocelot_write_rix), we were only writing 1 for
  Felix and Ocelot, which was their hardware-default value, and which
  there wasn't any intention in changing.
- In the case of SCH_NEXT_CFG, in fact Seville does not have this
  register field at all, and therefore, if we want to have common code
  we would be required to not write to it.

From 67c2404922c2c3f9cc0898aafaa4e3bea2bde084 Mon Sep 17 00:00:00 2001
From: Vladimir Oltean <vladimir.oltean@nxp.com>

Subject: net: dsa: felix: create a template for the DSA tags on xmit

With this patch we try to kill 2 birds with 1 stone.

First of all, some switches that use tag_ocelot.c don't have the exact
same bitfield layout for the DSA tags. The destination ports field is
different for Seville VSC9953 for example. So the choices are to either
duplicate tag_ocelot.c into a new tag_seville.c (sub-optimal) or somehow
take into account a supposed ocelot->dest_ports_offset when packing this
field into the DSA injection header (again not ideal).

Secondly, tag_ocelot.c already needs to memset a 128-bit area to zero
and call some packing() functions of dubious performance in the
fastpath. And most of the values it needs to pack are pretty much
constant (BYPASS=1, SRC_PORT=CPU, DEST=port index). So it would be good
if we could improve that.

The proposed solution is to allocate a memory area per port at probe
time, initialize that with the statically defined bits as per chip
hardware revision, and just perform a simpler memcpy in the fastpath.

Other alternatives have been analyzed, such as:
- Create a separate tag_seville.c: too much code duplication for just 1
  bit field difference.
- Create a separate DSA_TAG_PROTO_SEVILLE under tag_ocelot.c, just like
  tag_brcm.c, which would have a separate .xmit function. Again, too
  much code duplication for just 1 bit field difference.
- Allocate the template from the init function of the tag_ocelot.c
  module, instead of from the driver: couldn't figure out a method of
  accessing the correct port template corresponding to the correct
  tagger in the .xmit function.

Subject: net: mscc: ocelot: split writes to pause frame enable bit and to
 thresholds

We don't want ocelot_port_set_maxlen to enable pause frame TX, just to
adjust the pause thresholds.

Move the unconditional enabling of pause TX to ocelot_init_port. There
is no good place to put such setting because it shouldn't be
unconditional. But at the moment it is, we're not changing that.

Subject: net: mscc: ocelot: disable flow control on NPI interface

The Ocelot switches do not support flow control on Ethernet interfaces
where a DSA tag must be added. If pause frames are enabled, they will be
encapsulated in the DSA tag just like regular frames, and the DSA master
will not recognize them.

Subject: net: mscc: ocelot: extend watermark encoding function

The ocelot_wm_encode function deals with setting thresholds for pause
frame start and stop. In Ocelot and Felix the register layout is the
same, but for Seville, it isn't. The easiest way to accommodate Seville
hardware configuration is to introduce a function pointer for setting
this up.

Subject: net: dsa: felix: move probing to felix_vsc9959.c

Felix is not actually meant to be a DSA driver only for the switch
inside NXP LS1028A, but an umbrella for all Vitesse / Microsemi /
Microchip switches that are register-compatible with Ocelot and that are
using in DSA mode (with an NPI Ethernet port).

For the dsa_switch_ops exported by the felix driver to be generic enough
to be used by other non-PCI switches, we need to move the PCI-specific
probing to the low-level translation module felix_vsc9959.c. This way,
other switches can have their own probing functions, as platform devices
or otherwise.

This patch also removes the "Felix instance table", which did not stand
the test of time and is unnecessary at this point.

From 84705fc165526e8e55d208b2b10a48cc720a106a Mon Sep 17 00:00:00 2001
From: Maxim Kochetkov <fido_max@inbox.ru>
Date: Mon, 13 Jul 2020 19:57:10 +0300
Subject: net: dsa: felix: introduce support for Seville VSC9953 switch

This is another switch from Vitesse / Microsemi / Microchip, that has
10 ports (8 external, 2 internal) and is integrated into the Freescale /
NXP T1040 PowerPC SoC. It is very similar to Felix from NXP LS1028A,
except that this is a platform device and Felix is a PCI device, and it
doesn't support IEEE 1588 and TSN.

Like Felix, this driver configures its own PCS on the internal MDIO bus
using a phy_device abstraction for it (yes, it will be refactored to use
a raw mdio_device, like other phylink drivers do, but let's keep it like
that for now). But unlike Felix, the MDIO bus and the PCS are not from
the same vendor. The PCS is the same QorIQ/Layerscape PCS as found in
Felix/ENETC/DPAA*, but the internal MDIO bus that is used to access it
is actually an instantiation of drivers/net/phy/mdio-mscc-miim.c. But it
would be difficult to reuse that driver (it doesn't even use regmap, and
it's less than 200 lines of code), so we hand-roll here some internal
MDIO bus accessors within seville_vsc9953.c, which serves the purpose of
driving the PCS absolutely fine.

Also, same as Felix, the PCS doesn't support dynamic reconfiguration of
SerDes protocol, so we need to do pre-validation of PHY mode from device
tree and not let phylink change it.

Subject: docs: devicetree: add bindings for Seville DSA switch inside Felix
 driver

There are no non-standard bindings being used. However Felix is a PCI
device and Seville is a platform device. So give an example of device
tree for this switch and document its compatible string.

Subject: net: wan: cosa: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Subject: amd8111e: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GPF_ with a correct flag.
It has been compile tested.

When memory is allocated in 'amd8111e_init_ring()', GFP_ATOMIC must be used
because a spin_lock is hold.
One of the call chains is:
   amd8111e_open
   ** spin_lock_irq(&lp->lock);
   --> amd8111e_restart
      --> amd8111e_init_ring
   ** spin_unlock_irq(&lp->lock);

The rest of the patch is produced by coccinelle with a few adjustments to
please checkpatch.pl.

Subject: pcnet32: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GPF_ with a correct flag.
It has been compile tested.

When memory is allocated in 'pcnet32_realloc_tx_ring()' and
'pcnet32_realloc_rx_ring()', GFP_ATOMIC must be used because a spin_lock is
hold.
The call chain is:
   pcnet32_set_ringparam
   ** spin_lock_irqsave(&lp->lock, flags);
   --> pcnet32_realloc_tx_ring
   --> pcnet32_realloc_rx_ring
   ** spin_unlock_irqrestore(&lp->lock, flags);

When memory is in 'pcnet32_probe1()' and 'pcnet32_alloc_ring()', GFP_KERNEL
can be used.

While at it, update a few comments and pr_err messages to be more in line
with the new function names.

Subject: wan: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Subject: brcmfmac: To fix kernel crash on out of boundary access

To truncate the additional bytes, if extra bytes have been received.
Current code only have a warning and proceed without handling it.
But in one of the crash reported by DVT, these causes the
crash intermittently. So the processing is limit to the skb->len.

from drvr->mac to perm_addr. But at the moment, drvr->mac is all zero
array which causes permanent MAC address in wiphy is all zero as well.
To fix this, we set drvr->mac before setting perm_addr.

Subject: brcmfmac: keep SDIO watchdog running when console_interval is
 non-zero

brcmfmac host driver makes SDIO bus sleep and stops SDIO watchdog if no
pending event or data. As a result, host driver does not poll firmware
console buffer before buffer overflow, which leads to missing firmware
logs. We should not stop SDIO watchdog if console_interval is non-zero
in debug build.

Subject: brcmfmac: reduce maximum station interface from 2 to 1 in RSDB mode

The firmware state machines are not fully suitable for concurrent
station interface support, it may hit unexpected error if we have 2
different SSIDs and the roaming scenarios concurrently.
To avoid the bad user-experience if this is not fully validated, we
dis-allow user to create two concurrent station interfaces.

In wifi firmware, max length of IOCTL/IOVAR buffer size is 8192.
Increase the message buffer max size same as wifi firmware for control
packets so return buffers can come back.

Subject: brcmfmac: reserve 2 credits for host tx control path

It is observed that sometimes when sdiod is low in tx credits in low
rssi scenarios, the data path consumes all sdiod rx all credits and
there is no sdiod rx credit available for control path causing host
and card to go out of sync resulting in link loss between host and
card. So in order to prevent it some credits are reserved for control
path.

Note that TXCTL_CREDITS can't be larger than the firmware default
credit update threshold 2; otherwise there will be a deadlock for both
side waiting for each other.

Subject: brcmfmac: set state of hanger slot to FREE when flushing PSQ

When USB or SDIO device got abnormal bus disconnection, host driver
tried to clean up the skbs in PSQ and TXQ (The skb's pointer in hanger
slot linked to PSQ and TSQ), so we should set the state of skb hanger slot
to BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb.
In brcmf_fws_bus_txq_cleanup it already sets
BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb, therefore we add the
same thing in brcmf_fws_psq_flush to avoid following warning message.

Subject: brcmfmac: set pacing shift before transmitting skb to bus

Linux 3.6 introduces TSQ which has a per socket threshold for TCP Tx
packet to reduce latency. In flow control mode, host driver enqueues skb
in hanger and TCP doesn't push new skb frees until host frees the skb when
receiving fwstatus event. So set pacing shift 8 to send them as a single
large aggregate frame to the bus layer.

Subject: brcmfmac: Transform compatible string for FW loading

The driver relies on the compatible string from DT to determine which
FW configuration file it should load. The DTS spec allows for '/' as
part of the compatible string. We change this to '-' so that we will
still be able to load the config file, even when the compatible has a
'/'. This fixes explicitly the firmware loading for
"solidrun,cubox-i/q".

Subject: brcm80211: brcmsmac: Move LEDs to GPIO descriptors

The code in the BRCM80211 BRCMSMAC driver is using the legacy
GPIO API to to a complex check of the validity of the base of
the GPIO chip and whether it is present at all and then adding
an offset to the base of the chip.

Use the existing function to obtain a GPIO line internally
from a GPIO chip so we can use the offset directly and
modernize the code to use GPIO descriptors instead of integers
from the global GPIO numberspace.

Subject: bpf: Fix build for disabled CONFIG_DEBUG_INFO_BTF option

Stephen reported following linker warnings on powerpc build:

  ld: warning: orphan section `.BTF_ids' from `kernel/trace/bpf_trace.o' being placed in section `.BTF_ids'
  ld: warning: orphan section `.BTF_ids' from `kernel/bpf/btf.o' being placed in section `.BTF_ids'
  ld: warning: orphan section `.BTF_ids' from `kernel/bpf/stackmap.o' being placed in section `.BTF_ids'
  ld: warning: orphan section `.BTF_ids' from `net/core/filter.o' being placed in section `.BTF_ids'
  ld: warning: orphan section `.BTF_ids' from `kernel/trace/bpf_trace.o' being placed in section `.BTF_ids'

It's because we generated .BTF_ids section even when
CONFIG_DEBUG_INFO_BTF is not enabled. Fixing this by
generating empty btf_id arrays for this case.

Subject: bpf: Fix cross build for CONFIG_DEBUG_INFO_BTF option

Stephen and 0-DAY CI Kernel Test Service reported broken cross build
for arm (arm-linux-gnueabi-gcc (GCC) 9.3.0), with following output:

   /tmp/ccMS5uth.s: Assembler messages:
   /tmp/ccMS5uth.s:69: Error: unrecognized symbol type ""
   /tmp/ccMS5uth.s:82: Error: unrecognized symbol type ""

Having '@object' for .type  diretive is  wrong because '@' is comment
character for some architectures. Using STT_OBJECT instead that should
work everywhere.

Also using HOST* variables to build resolve_btfids so it's properly
build in crossbuilds (stolen from objtool's Makefile).

Subject: wilc1000: let wilc_mac_xmit() return NETDEV_TX_OK

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type defining 'NETDEV_TX_OK' but this
driver returns '0' instead of 'NETDEV_TX_OK'.

Fix this by returning 'NETDEV_TX_OK' instead of '0'.

Subject: bpfilter: Allow to build bpfilter_umh as a module without static
 library

Originally, bpfilter_umh was linked with -static only when
CONFIG_BPFILTER_UMH=y.

Commit 8a2cc0505cc4 ("bpfilter: use 'userprogs' syntax to build
bpfilter_umh") silently, accidentally dropped the CONFIG_BPFILTER_UMH=y
test in the Makefile. Revive it in order to link it dynamically when
CONFIG_BPFILTER_UMH=m.

Since commit b1183b6dca3e ("bpfilter: check if $(CC) can link static
libc in Kconfig"), the compiler must be capable of static linking to
enable CONFIG_BPFILTER_UMH, but it requires more than needed.

To loosen the compiler requirement, I changed the dependency as follows:

    depends on CC_CAN_LINK
    depends on m || CC_CAN_LINK_STATIC

If CONFIG_CC_CAN_LINK_STATIC in unset, CONFIG_BPFILTER_UMH is restricted
to 'm' or 'n'.

In theory, CONFIG_CC_CAN_LINK is not required for CONFIG_BPFILTER_UMH=y,
but I did not come up with a good way to describe it.

Extend switchdev API to add support for MRP interconnect. The HW is
notified in the following cases:

SWITCHDEV_OBJ_ID_IN_ROLE_MRP: This is used when the interconnect role
  of the node changes. The supported roles are MIM and MIC.

SWITCHDEV_OBJ_ID_IN_STATE_MRP: This is used when the interconnect ring
  changes it states to open or closed.

SWITCHDEV_OBJ_ID_IN_TEST_MRP: This is used to start/stop sending
  MRP_InTest frames on all MRP ports. This is called only on nodes that
  have the interconnect role MIM.

  or MIC) and the port ifindex that represents the interconnect port.

IFLA_BRIDGE_MRP_IN_STATE - the parameter type is br_mrp_in_state which
  contains the interconnect id and the interconnect state.

IFLA_BRIDGE_MRP_IN_TEST - the parameter type is br_mrp_start_in_test
  which contains the interconnect id, the interval at which to send
  MRP_InTest frames, how many test frames can be missed before declaring
  the interconnect ring open and the period which represents for how long
  to send MRP_InTest frames.

This patch extends the 'struct br_mrp' to contain information regarding
the MRP interconnect. It contains the following:
- the interconnect port 'i_port', which is NULL if the node doesn't have
  a interconnect role
- the interconnect id, which is similar with the ring id, but this field
  is also part of the MRP_InTest frames.
- the interconnect role, which can be MIM or MIC.
- the interconnect state, which can be open or closed.
- the interconnect delayed_work for sending MRP_InTest frames and check
  for lost of continuity.

Subject: bridge: mrp: Rename br_mrp_port_open to br_mrp_ring_port_open

This patch renames the function br_mrp_port_open to
br_mrp_ring_port_open. In this way is more clear that a ring port lost
the continuity because there will be also a br_mrp_in_port_open.

Subject: bridge: mrp: Implement the MRP Interconnect API

Thie patch adds support for MRP Interconnect. Similar with the MRP ring,
if the HW can't generate MRP_InTest frames, then the SW will try to
generate them. And if also the SW fails to generate the frames then an
error is return to userspace.

The forwarding/termination of MRP_In frames is happening in the kernel
and is done by MRP instances.

Subject: bridge: mrp: Extend MRP netlink interface for configuring MRP
 interconnect

This patch extends the existing MRP netlink interface with the following
attributes: IFLA_BRIDGE_MRP_IN_ROLE, IFLA_BRIDGE_MRP_IN_STATE and
IFLA_BRIDGE_MRP_START_IN_TEST. These attributes are similar with their
ring attributes but they apply to the interconnect port.

Subject: bridge: uapi: mrp: Extend MRP_INFO attributes for interconnect status

Extend the existing MRP_INFO to return status of MRP interconnect. In
case there is no MRP interconnect on the node then the role will be
disabled so the other attributes can be ignored.

Subject: lan743x: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GPF_ with a correct flag.
It has been compile tested.

When memory is allocated in 'lan743x_tx_ring_cleanup()' and
'lan743x_rx_ring_init()', GFP_KERNEL can be used because this flag is
already used to allocate some memory in these functions.

While at it, remove a useless (void *) casting in the first hunk in so that
the code is more consistent.

When memory is allocated in 'init_shared_mem()' GFP_KERNEL can be used

While at it, update some debug message to match the new function names.

Subject: net: neterion: vxge: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below. No GFP_
flag needs to be corrected.
It has been compile tested.

Subject: mlxsw: spectrum_span: Add per-ASIC SPAN agent operations

The various SPAN agent types differ in their mirror targets (i.e.,
physical port netdev vs. VLAN netdev) and the encapsulation headers that
they need to encapsulate the mirrored packets with.

The Spectrum-2 and Spectrum-3 ASICs support a SPAN agent type that is
able to mirror towards the CPU, whereas the Spectrum-1 ASIC does not.

Prepare for the addition of this new SPAN agent type by splitting the
SPAN agent operations to be per-ASIC.

Subject: mlxsw: spectrum_span: Add driver private info to parms_set() callback

The parms_set() callback is supposed to fill in the parameters for the
SPAN agent, such as the destination port and encapsulation info, if any.

When mirroring to the CPU port we cannot resolve the destination port
(the CPU port) without access to the driver private info.

Pass the driver private info to parms_set() callback so that it could be
used later on to resolve the CPU port.

Subject: mlxsw: spectrum_span: Do not dereference destination netdev

Currently, the destination netdev to which we mirror must be a valid
netdev. However, this is going to change with the introduction of
mirroring towards the CPU port, as the CPU port does not have a backing
netdev.

Avoid dereferencing the destination netdev when it is not clear if it is
valid or not.

Subject: mlxsw: spectrum_span: Add support for mirroring towards CPU port

The Spectrum-2 and Spectrum-3 ASICs are able to mirror packets towards
the CPU. These packets are then trapped like any other packet, but with
a special packet trap and additional metadata such as why the packet was
mirrored.

The ability to mirror packets towards the CPU will be utilized by a
subsequent patch set that will mirror packets that were dropped by the
ASIC for various buffer-related reasons, such as tail-drop and
early-drop.

Add mirroring towards the CPU as a new SPAN agent type and re-use the
functions that mirror to a physical port where possible.

Subject: mlxsw: spectrum_span: Allow passing parameters to SPAN agents

Currently, the only parameter of a SPAN agent is the netdev which
the SPAN agent should mirror to.

The next patch will add the ability to request a SPAN agent that mirrors
to a specific netdev and has a specific policer ID bound to it. This is
required when mirroring packets to the CPU port.

Therefore, encapsulate the sole parameter to mlxsw_sp_span_agent_get()
in a structure, so that it could later be extended with policer
information.

Subject: mlxsw: spectrum_span: Allow setting policer on a SPAN agent

When mirroring packets to the CPU port the mirrored packets are trapped
to the CPU. However, unlike other traps, it is not possible to set a
policer on the associated trap group. Instead, the policer needs to be
set on the SPAN agent.

Moreover, the policer ID must be within a specified range: From a
configurable (even) base ID to this base plus the maximum number of SPAN
agents.

While the immediate use case is to set the policer on a SPAN agent that
mirrors to the CPU port, a policer can be set on any SPAN agent.
Therefore, the operation is implemented for all SPAN agent types.

Extend the SPAN agent request API to allow passing the desired policer
ID that should be bound to the SPAN agent. Return an error for
Spectrum-1, as it does not support policer setting on a SPAN agent.

Subject: mlxsw: reg: Increase trap identifier to 10 bits

The trap identifier was increased to 10 bits in new versions of the
Programmer's Reference Manual (PRM).

Increase it accordingly in the Host PacKet Trap (HPKT) register and in
the Completion Queue Element (CQE).

This is significant for subsequent patches that will introduce trap
identifiers which utilize the extended range.

Subject: mlxsw: core: Use mirror reason during Rx listener lookup

The Rx listener abstraction allows the switch driver (e.g.,
mlxsw_spectrum) to register a function that is called when a packet is
received (trapped) for a specific reason.

Up until now, the Rx listener lookup was solely based on the trap
identifier. However, when a packet is mirrored to the CPU the trap
identifier merely indicates that the packet was mirrored, but not why it
was mirrored. This makes it impossible for the switch driver to register
different Rx listeners for different mirror reasons.

Solve this by allowing the switch driver to register a Rx listener with
a mirror reason and by extending the Rx listener lookup to take the
mirror reason into account.

Subject: s390/qeth: don't clear the configured isolation mode

When qeth_set_access_ctrl_online() is called during the device's
initialization and discovers that isolation mode isn't supported, don't
clear the user's currently configured mode.
They intentionally choose to operate the device in this specific mode,
and degrading the isolation is not an option.

Only adjust the configuration when called via sysfs (ie. fallback = 1),
and here follow the common pattern and restore it from prev_isolation.

Subject: s390/qeth: clean up error handling for isolation mode cmds

As the cmd IO path has learned to propagate errnos back to its callers,
let them deal with errors instead of trying to restore their previous
configuration from within the IO error path.

Also translate the HW error to a meaningful errno, instead of returning
-EIO for all cases (and don't map this to -EOPNOTSUPP later on...).

While at it, add a READ_ONCE() / WRITE_ONCE() pair to ensure that the
data path always sees a valid isolation mode during reconfiguration.

Subject: s390/qeth: unify RX-mode hashtables

To keep track of the addresses programmed from an RX modeset, we have
two separate hashtables (L2: mac_htable, L3: ip_mc_htable).

These are never used at the same time, so unify them into a single
rx_mode_addrs hashtable.

Subject: r8169: add support for RTL8125B

Add support for RTL8125B rev.b. In my tests 2.5Gbps worked well
w/o firmware, however for a stable link at 1Gbps firmware revision
0.0.2 is needed.

Subject: ksz884x: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'ksz_alloc_desc()', GFP_KERNEL can be used
because a few lines below, GFP_KERNEL is also used in the
'ksz_alloc_soft_desc()' calls.

Subject: nfp: convert to new udp_tunnel_nic infra

NFP conversion is pretty straightforward. We want to be able
to sleep, and only get callbacks when the device is open.

NFP did not ask for port replay when ports were removed, now
new infra will provide this feature for free.

Subject: be2net: convert to new udp_tunnel_nic infra

Convert be2net to new udp_tunnel_nic infra. NIC only takes one VxLAN
port. Remove the port tracking using a list. The warning in
be_work_del_vxlan_port() looked suspicious - like the driver expected
ports to be removed in order of addition.

be2net unregisters ports when going down and re-registers them (for
skyhawk) when coming up, but it never checks if the device is up
in the add_port / del_port callbacks. Make it use
UDP_TUNNEL_NIC_INFO_OPEN_ONLY. Sadly this driver calls its own
open/close functions directly so the udp_tunnel_nic_reset_ntf()
workaround is needed.

Subject: xgbe: switch to more generic VxLAN detection

Instead of looping though the list of ports just check
if the geometry of the packet is correct for VxLAN.
HW most likely doesn't care about the exact port, anyway,
since only first port is actually offloaded, and this way
we won't have to maintain the port list at all.

Subject: xgbe: convert to new udp_tunnel_nic infra

Make use of the new udp_tunnel_nic infra. Don't clear the features
when VxLAN port is not present to make all drivers behave the same.
Driver will now (until we address the problem in the core) leave
the RX UDP tunnel feature always on, since this is what most drivers
do.

Remove the list of VxLAN ports, just program the one core told us to.

The driver seem to want to clear the VxLAN ports on close but it
doesn't seem to flush the port list properly so it'd get wrong
use counts after close/open. Again since it calls its own open
handler we need the reset notification hack.

v2:
 - fix kbuild warning

Subject: bnx2x: convert to new udp_tunnel_nic infra

Fairly straightforward conversion - no need to keep track
of the use count, and replay when ports get removed, also
callbacks can just sleep.

Subject: cxgb4: convert to new udp_tunnel_nic infra

Convert to new infra, this driver is very simple. The check of
adapter->rawf_cnt in cxgb_udp_tunnel_unset_port() is kept from
the old port deletion function but it's dodgy since nothing ever
updates that member once its set during init. Also .set_port
callback always adds the raw mac filter..

Subject: enic: convert to new udp_tunnel_nic infra

Convert to new infra, now the refcounting will be correct,
and driver gets port replay of other ports when offloaded
port gets removed.

Subject: fm10k: convert to new udp_tunnel_nic infra

Straightforward conversion to new infra. Driver restores info
after close/open cycle by calling its internal restore function
so just use that, no need for udp_tunnel_nic_reset_ntf() here.

Subject: rtw88: 8821c: add set tx power index

To configure the transmit power of 8821c implement trasmit
power index setting callback function for 8821c. This is very
similar to the callback function of 8822b.

Subject: rtw88: 8821c: add query rx desc support

Some RX packets contain also information about environment status.

Implement rtw_chip_ops::query_rx_desc() for 8821c. Parse the RX
descriptor which describes the current condition of the received
packet.

Subject: rtw88: 8821c: add false alarm statistics

False alarm statistics can be used to adjust the RX gain. This
helps the driver to adapt to different circumstances.

Implement rtw_chip_ops::false_alarm_statistics() for 8821c.

Subject: rtw88: 8821c: add phy calibration

In order to get a better TX EVM, do calibration after association.

The calibration needed for 8821c is the IQK, which is done in the
firmware. Implement the rtw_chip_ops::phy_calibration() to trigger
firmware to calibrate.

Subject: rtw88: 8821c: add cck pd settings

CCK PD can reduce the number of false alarm of the CCK rates.
It dynamically adjusts the power threshold and CS ratio.
The values are compared to the values of the previous level, if
the level is changed, set new values of power threshold and CS
ratio.

Implement rtw_chip_ops::cck_pd_set() for 8821c.

Subject: rtw88: 8821c: add power tracking

The TX power requires to be adjusted based on the thermal value.
The actual power will decrease if the thermal value raised, and
will increase if the thermal value lowered. Driver comapres the
thermal value, as moving averages. If it changes over a limit,
driver will modify the TX power index to compensate.

Implement rtw_chip_ops::pwr_track() for 8821c.

Subject: rtw88: 8821c: add beamformee support

Beamforming is used for directional signal transmission/reception.
Beamformee plays the role for signal reception, and makes the RX
performance better in middle distance range.

Implement beamformee related callbacks for 8821c.

Since 8821c only support 1ss rate, nc_index in beamformee setting
needs to be adjusted based on the capability.

Subject: rtw88: pci: disable aspm for platform inter-op with module parameter

Some platforms cannot read the DBI register successfully for the
ASPM settings. After the read failed, the bus could be unstable,
and the device just became unavailable [1]. For those platforms,
the ASPM should be disabled. But as the ASPM can help the driver
to save the power consumption in power save mode, the ASPM is still
needed. So, add a module parameter for them to disable it, then
the device can still work, while others can benefit from the less
power consumption that brings by ASPM enabled.

[2] Note that my lenovo T430 is the same.

Subject: wlcore: Simplify runtime resume ELP path

We can simplify the runtime resume ELP path by always setting and
clearing the completion in runtime resume. This way we can test for
WL1271_FLAG_IRQ_RUNNING after the resume write to see if we need
completion at all.

And in wlcore_irq(), we need to take spinlock for running the
completion and for the pm_wakeup_event(). Spinlock is not needed
around the bitops flags check for WL1271_FLAG_SUSPENDED so the
spinlocked sections get shorter.

Subject: mwifiex: Fix reporting 'operation not supported' error code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ENOTSUPP (double PP) is internal linux kernel code 524 available only in
kernel include file linux/errno.h and not exported to userspace.

EOPNOTSUPP (OP; double PP) is standard code 95 for reporting 'operation not
supported' available via kernel include file uapi/asm-generic/errno.h.

ENOTSUP (single P) is alias for EOPNOTSUPP defined only in userspace
include file bits/errno.h and not available in kernel.

Because Linux kernel does not support ENOTSUP (single P) and because
userspace does not support ENOTSUPP (double PP), report error code for
'operation not supported' via EOPNOTSUPP macro.

This patch fixes problem that mwifiex kernel driver sends to userspace
unsupported error codes like: "failed: -524 (No error information)".
After applying this patch userspace see: "failed: -95 (Not supported)".

Subject: mwifiex: Prevent memory corruption handling keys

The length of the key comes from the network and it's a 16 bit number.  It
needs to be capped to prevent a buffer overflow.

From: Zong-Zhe Yang <kevin_yang@realtek.com>

Subject: rtw88: coex: Fix ACL Tx pause during BT inquiry/page.

Add a set of logic with corresponding coexistence parameters to
handle the situation under BT inquiry/page.

We will set PSTDMA while WL-Busy + BT inquiry/page to separate
WL/BT slots. PSTDMA can protect WL data rate and BT performance.

If WL-Busy + BT inquiry/page and there was BT device paired,
We will set the mechanism to 4Slot PSTDMA.
In 4Slot PSTDMA, the paired devices can perform more smoothly
and prevent some issues trigger from insufficient data.

And to avoid A2DP glitch or disconnection, we will adjust ACL
data priority higher than inquiry/page.

In addition, we found sometimes BT inquiry/page still working
last for seconds after BT had notified inquiry/page finished.
It will lead to A2DP glitch cause of ACL data, inquiry/page
priority toggled. To fix the corner, we add a timer to remain
the inquiry/page status.

And we found WL busy/idle threshold is too sensitive,
it will keep switching in some weak network environment and
coexistence mechanism will switch between TDMA and PSTDMA.

The very frequently switching may destroyed not only the
handshake with AP, but BT performance. And it will trigger
some unexpected error.

To prevent the frequently switching, we add a timer to delay
the status change while WL busy switch to idle.

Subject: b43: Remove uninitialized_var() usage

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings (e.g.
"unused variable"). If the compiler thinks it is uninitialized, either
simply initialize the variable or make compiler changes. As a precursor
to removing[2] this[3] macro[4], just initialize this variable to NULL.
No later NULL deref is possible due to the early returns outside of the
(phy->rev >= 7 && phy->rev < 19) case, which explicitly tests for NULL.

Subject: rtlwifi: rtl8192cu: Remove uninitialized_var() usage

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings (e.g.
"unused variable"). If the compiler thinks it is uninitialized, either
simply initialize the variable or make compiler changes. As a precursor
to removing[2] this[3] macro[4], just initialize this variable to NULL,
and avoid sending garbage by returning.

Subject: rtl818x_pci: use generic power management

Earlier, drivers had to manage the device's power states, and related
operations, themselves. With the generic approach, these are done by PCI
core.

The only driver-specific jobs, .suspend() and .resume() doing were invoking
PCI helper functions pci_save/restore_state() and
pci_set_power_state(). This is not recommeneded as PCI core takes care of
that. Hence they became empty-body functions, thus define them NULL.

Compile-tested only.

Subject: orinoco: use generic power management

With the support of generic PM callbacks, drivers no longer need to use
legacy .suspend() and .resume() in which they had to maintain PCI states
changes and device's power state themselves. The required operations are
done by PCI core.

PCI drivers are not expected to invoke PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(),
pci_set_power_state(), etc. Their tasks are completed by PCI core itself.

Compile-tested only.

Subject: adm8211: use generic power management

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

In the case of adm8211, after removing PCI helper functions, .suspend()
and .resume() became empty-body functions. Hence, define them NULL and
use dev_pm_ops.

Compile-tested only.

device's power states and takes care of register states.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

The driver was invoking PCI helper functions like pci_save/restore_state(),
pci_enable/disable_device() and pci_set_power_state(), which is not
recommended.

Compile-tested only.

Subject: Bluetooth: Add per-instance adv disable/remove

Add functionality to disable and remove advertising instances,
and use that functionality in MGMT add/remove advertising calls.

Currently, advertising is globally-disabled, i.e. all instances are
disabled together, even if hardware offloading is available. This
patch adds functionality to disable and remove individual adv
instances, solving two issues:

1. On new advertisement registration, a global disable was done, and
then only the new instance was enabled. This meant only the newest
instance was actually enabled.

2. On advertisement removal, the structure was removed, but the instance
was never disabled or removed, which is incorrect with hardware offload
support.

Subject: ssb: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Subject: iwlegacy: Check the return value of pcie_capability_read_*()

On failure pcie_capability_read_dword() sets it's last parameter, val
to 0. However, with Patch 14/14, it is possible that val is set to ~0 on
failure. This would introduce a bug because (x & x) == (~0 & x).

This bug can be avoided without changing the function's behaviour if the
return value of pcie_capability_read_dword is checked to confirm success.

Check the return value of pcie_capability_read_dword() to ensure success.

Subject: docs: networking: timestamping: add section for stacked PHC devices

The concept of timestamping DSA switches / Ethernet PHYs is becoming
more and more popular, however the Linux kernel timestamping code has
evolved quite organically and there's layers upon layers of new and old
code that need to work together for things to behave as expected.

Add this chapter to explain what the overall goals are.

Loosely based upon this email discussion plus some more info:

   this would occur at a later time in the processing pipeline than other
   software time stamping and therefore could lead to unexpected deltas
   between time stamps.
+
+3.2 Special considerations for stacked PTP Hardware Clocks
+----------------------------------------------------------
+
+There are situations when there may be more than one PHC (PTP Hardware Clock)
+in the data path of a packet. The kernel has no explicit mechanism to allow the
+user to select which PHC to use for timestamping Ethernet frames. Instead, the
+assumption is that the outermost PHC is always the most preferable, and that
+kernel drivers collaborate towards achieving that goal. Currently there are 3
+cases of stacked PHCs, detailed below:
+
+3.2.1 DSA (Distributed Switch Architecture) switches
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+These are Ethernet switches which have one of their ports connected to an
+(otherwise completely unaware) host Ethernet interface, and perform the role of
+a port multiplier with optional forwarding acceleration features.  Each DSA
+switch port is visible to the user as a standalone (virtual) network interface,
+and its network I/O is performed, under the hood, indirectly through the host
+interface (redirecting to the host port on TX, and intercepting frames on RX).
+
+When a DSA switch is attached to a host port, PTP synchronization has to
+suffer, since the switch's variable queuing delay introduces a path delay
+jitter between the host port and its PTP partner. For this reason, some DSA
+switches include a timestamping clock of their own, and have the ability to
+perform network timestamping on their own MAC, such that path delays only
+measure wire and PHY propagation latencies. Timestamping DSA switches are
+supported in Linux and expose the same ABI as any other network interface (save
+for the fact that the DSA interfaces are in fact virtual in terms of network
+I/O, they do have their own PHC).  It is typical, but not mandatory, for all
+interfaces of a DSA switch to share the same PHC.
+
+By design, PTP timestamping with a DSA switch does not need any special
+handling in the driver for the host port it is attached to.  However, when the
+host port also supports PTP timestamping, DSA will take care of intercepting
+the ``.ndo_do_ioctl`` calls towards the host port, and block attempts to enable
+hardware timestamping on it. This is because the SO_TIMESTAMPING API does not
+allow the delivery of multiple hardware timestamps for the same packet, so
+anybody else except for the DSA switch port must be prevented from doing so.
+
+In code, DSA provides for most of the infrastructure for timestamping already,
+in generic code: a BPF classifier (``ptp_classify_raw``) is used to identify
+PTP event messages (any other packets, including PTP general messages, are not
+timestamped), and provides two hooks to drivers:
+
+- ``.port_txtstamp()``: The driver is passed a clone of the timestampable skb
+  to be transmitted, before actually transmitting it. Typically, a switch will
+  have a PTP TX timestamp register (or sometimes a FIFO) where the timestamp
+  becomes available. There may be an IRQ that is raised upon this timestamp's
+  availability, or the driver might have to poll after invoking
+  ``dev_queue_xmit()`` towards the host interface. Either way, in the
+  ``.port_txtstamp()`` method, the driver only needs to save the clone for
+  later use (when the timestamp becomes available). Each skb is annotated with
+  a pointer to its clone, in ``DSA_SKB_CB(skb)->clone``, to ease the driver's
+  job of keeping track of which clone belongs to which skb.
+
+- ``.port_rxtstamp()``: The original (and only) timestampable skb is provided
+  to the driver, for it to annotate it with a timestamp, if that is immediately
+  available, or defer to later. On reception, timestamps might either be
+  available in-band (through metadata in the DSA header, or attached in other
+  ways to the packet), or out-of-band (through another RX timestamping FIFO).
+  Deferral on RX is typically necessary when retrieving the timestamp needs a
+  sleepable context. In that case, it is the responsibility of the DSA driver
+  to call ``netif_rx_ni()`` on the freshly timestamped skb.
+
+3.2.2 Ethernet PHYs
+^^^^^^^^^^^^^^^^^^^
+
+These are devices that typically fulfill a Layer 1 role in the network stack,
+hence they do not have a representation in terms of a network interface as DSA
+switches do. However, PHYs may be able to detect and timestamp PTP packets, for
+performance reasons: timestamps taken as close as possible to the wire have the
+potential to yield a more stable and precise synchronization.
+
+A PHY driver that supports PTP timestamping must create a ``struct
+mii_timestamper`` and add a pointer to it in ``phydev->mii_ts``. The presence
+of this pointer will be checked by the networking stack.
+
+Since PHYs do not have network interface representations, the timestamping and
+ethtool ioctl operations for them need to be mediated by their respective MAC
+driver.  Therefore, as opposed to DSA switches, modifications need to be done
+to each individual MAC driver for PHY timestamping support. This entails:
+
+- Checking, in ``.ndo_do_ioctl``, whether ``phy_has_hwtstamp(netdev->phydev)``
+  is true or not. If it is, then the MAC driver should not process this request
+  but instead pass it on to the PHY using ``phy_mii_ioctl()``.
+
+- On RX, special intervention may or may not be needed, depending on the
+  function used to deliver skb's up the network stack. In the case of plain
+  ``netif_rx()`` and similar, MAC drivers must check whether
+  ``skb_defer_rx_timestamp(skb)`` is necessary or not - and if it is, don't
+  call ``netif_rx()`` at all.  If ``CONFIG_NETWORK_PHY_TIMESTAMPING`` is
+  enabled, and ``skb->dev->phydev->mii_ts`` exists, its ``.rxtstamp()`` hook
+  will be called now, to determine, using logic very similar to DSA, whether
+  deferral for RX timestamping is necessary.  Again like DSA, it becomes the
+  responsibility of the PHY driver to send the packet up the stack when the
+  timestamp is available.
+
+  For other skb receive functions, such as ``napi_gro_receive`` and
+  ``netif_receive_skb``, the stack automatically checks whether
+  ``skb_defer_rx_timestamp()`` is necessary, so this check is not needed inside
+  the driver.
+
+- On TX, again, special intervention might or might not be needed.  The
+  function that calls the ``mii_ts->txtstamp()`` hook is named
+  ``skb_clone_tx_timestamp()``. This function can either be called directly
+  (case in which explicit MAC driver support is indeed needed), but the
+  function also piggybacks from the ``skb_tx_timestamp()`` call, which many MAC
+  drivers already perform for software timestamping purposes. Therefore, if a
+  MAC supports software timestamping, it does not need to do anything further
+  at this stage.
+
+3.2.3 MII bus snooping devices
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+These perform the same role as timestamping Ethernet PHYs, save for the fact
+that they are discrete devices and can therefore be used in conjunction with
+any PHY even if it doesn't support timestamping. In Linux, they are
+discoverable and attachable to a ``struct phy_device`` through Device Tree, and
+for the rest, they use the same mii_ts infrastructure as those. See
+Documentation/devicetree/bindings/ptp/timestamper.txt for more details.
+
+3.2.4 Other caveats for MAC drivers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Stacked PHCs, especially DSA (but not only) - since that doesn't require any
+modification to MAC drivers, so it is more difficult to ensure correctness of
+all possible code paths - is that they uncover bugs which were impossible to
+trigger before the existence of stacked PTP clocks.  One example has to do with
+this line of code, already presented earlier::
+
+      skb_shinfo(skb)->tx_flags |= SKBTX_IN_PROGRESS;
+
+Any TX timestamping logic, be it a plain MAC driver, a DSA switch driver, a PHY
+driver or a MII bus snooping device driver, should set this flag.
+But a MAC driver that is unaware of PHC stacking might get tripped up by
+somebody other than itself setting this flag, and deliver a duplicate
+timestamp.
+For example, a typical driver design for TX timestamping might be to split the
+transmission part into 2 portions:
+
+1. "TX": checks whether PTP timestamping has been previously enabled through
+   the ``.ndo_do_ioctl`` ("``priv->hwtstamp_tx_enabled == true``") and the
+   current skb requires a TX timestamp ("``skb_shinfo(skb)->tx_flags &
+   SKBTX_HW_TSTAMP``"). If this is true, it sets the
+   "``skb_shinfo(skb)->tx_flags |= SKBTX_IN_PROGRESS``" flag. Note: as
+   described above, in the case of a stacked PHC system, this condition should
+   never trigger, as this MAC is certainly not the outermost PHC. But this is
+   not where the typical issue is.  Transmission proceeds with this packet.
+
+2. "TX confirmation": Transmission has finished. The driver checks whether it
+   is necessary to collect any TX timestamp for it. Here is where the typical
+   issues are: the MAC driver takes a shortcut and only checks whether
+   "``skb_shinfo(skb)->tx_flags & SKBTX_IN_PROGRESS``" was set. With a stacked
+   PHC system, this is incorrect because this MAC driver is not the only entity
+   in the TX data path who could have enabled SKBTX_IN_PROGRESS in the first
+   place.
+
+The correct solution for this problem is for MAC drivers to have a compound
+check in their "TX confirmation" portion, not only for
+"``skb_shinfo(skb)->tx_flags & SKBTX_IN_PROGRESS``", but also for
+"``priv->hwtstamp_tx_enabled == true``". Because the rest of the system ensures
+that PTP timestamping is not enabled for anything other than the outermost PHC,
+this enhanced check will avoid delivering a duplicated TX timestamp to user
+space.

Subject: mlxsw: spectrum_policer: Add policer core

Add common code to handle all policer-related functionality in mlxsw.
Currently, only policer for policy engines are supported, but it in the
future more policer families will be added such as CPU (trap) policers
and storm control policers.

The API allows different modules to add / delete policers and read their
drop counter.

Subject: mlxsw: core_acl_flex_actions: Work around hardware limitation

In the policy engine, each ACL rule points to an action block where the
ACL actions are stored. Each action block consists of one or more action
sets. Each action set holds one or more individual actions, up to a
maximum queried from the device. For example:

                        Action set #1               Action set #2

+----------+          +--------------+            +--------------+
| ACL rule +---------->  Action #1   |      +----->  Action #4   |
+----------+          +--------------+      |     +--------------+
                      |  Action #2   |      |     |  Action #5   |
                      +--------------+      |     +--------------+
                      |  Action #3   +------+     |              |
                      +--------------+            +--------------+

                      <---------+ Action block +----------------->

The hardware has a limitation that prevents a policing action
(MLXSW_AFA_POLCNT_CODE when used with a policer, not a counter) from
being configured in the same action set with a trap action (i.e.,
MLXSW_AFA_TRAP_CODE or MLXSW_AFA_TRAPWU_CODE). Note that the latter used
to implement multiple actions: 'trap', 'mirred', 'drop'.

Work around this limitation by teaching mlxsw_afa_block_append_action()
to create a new action set not only when there is no more room left in
the current set, but also when there is a conflict between previously
mentioned actions.

Subject: mlxsw: core_acl_flex_actions: Add police action

Add core functionality required to support police action in the policy
engine.

The utilized hardware policers are stored in a hash table keyed by the
flow action index. This allows to support policer sharing between
multiple ACL rules.

Subject: selftests: forwarding: Add tc-police tests

Test tc-police action in various scenarios such as Rx policing, Tx
policing, shared policer and police piped to mirred. The test passes
with both veth pairs and loopbacked ports.

# ./tc_police.sh
TEST: police on rx                                                  [ OK ]
TEST: police on tx                                                  [ OK ]
TEST: police with shared policer - rx                               [ OK ]
TEST: police with shared policer - tx                               [ OK ]
TEST: police rx and mirror                                          [ OK ]
TEST: police tx and mirror                                          [ OK ]

Subject: Bluetooth: Fix update of connection state in `hci_encrypt_cfm`

Starting with the upgrade to v5.8-rc3, I've noticed I wasn't able to
connect to my Bluetooth headset properly anymore. While connecting to
the device would eventually succeed, bluetoothd seemed to be confused
about the current connection state where the state was flapping hence
and forth. Bisecting this issue led to commit 3ca44c16b0dc (Bluetooth:
Consolidate encryption handling in hci_encrypt_cfm, 2020-05-19), which
refactored `hci_encrypt_cfm` to also handle updating the connection
state.

The commit in question changed the code to call `hci_connect_cfm` inside
`hci_encrypt_cfm` and to change the connection state. But with the
conversion, we now only update the connection state if a status was set
already. In fact, the reverse should be true: the status should be
updated if no status is yet set. So let's fix the isuse by reversing the
condition.

Commit 77361825bb01 ("bpf: cpumap use ptr_ring_consume_batched") changed
away from using single frame ptr_ring dequeue (__ptr_ring_consume) to
consume a batched, but it uses a locked version, which as the comment
explain isn't needed.

Change to use the non-locked version __ptr_ring_consume_batched.

Subject: cpumap: Formalize map value as a named struct

As it has been already done for devmap, introduce 'struct bpf_cpumap_val'
to formalize the expected values that can be passed in for a CPUMAP.
Update cpumap code to use the struct.

Subject: bpf: cpumap: Add the possibility to attach an eBPF program to cpumap

Introduce the capability to attach an eBPF program to cpumap entries.
The idea behind this feature is to add the possibility to define on
which CPU run the eBPF program if the underlying hw does not support
RSS. Current supported verdicts are XDP_DROP and XDP_PASS.

This patch has been tested on Marvell ESPRESSObin using xdp_redirect_cpu
sample available in the kernel tree to identify possible performance
regressions. Results show there are no observable differences in
packet-per-second:

$./xdp_redirect_cpu --progname xdp_cpu_map0 --dev eth0 --cpu 1
rx: 354.8 Kpps
rx: 356.0 Kpps
rx: 356.8 Kpps
rx: 356.3 Kpps
rx: 356.6 Kpps
rx: 356.6 Kpps
rx: 356.7 Kpps
rx: 355.8 Kpps
rx: 356.8 Kpps
rx: 356.8 Kpps

Subject: bpf: cpumap: Implement XDP_REDIRECT for eBPF programs attached to map
 entries

Introduce XDP_REDIRECT support for eBPF programs attached to cpumap
entries.
This patch has been tested on Marvell ESPRESSObin using a modified
version of xdp_redirect_cpu sample in order to attach a XDP program
to CPUMAP entries to perform a redirect on the mvneta interface.
In particular the following scenario has been tested:

rq (cpu0) --> mvneta - XDP_REDIRECT (cpu0) --> CPUMAP - XDP_REDIRECT (cpu1) --> mvneta

$./xdp_redirect_cpu -p xdp_cpu_map0 -d eth0 -c 1 -e xdp_redirect \
	-f xdp_redirect_kern.o -m tx_port -r eth0

tx: 285.2 Kpps rx: 285.2 Kpps

Attaching a simple XDP program on eth0 to perform XDP_TX gives
comparable results:

tx: 288.4 Kpps rx: 288.4 Kpps

Subject: samples/bpf: xdp_redirect_cpu: Load a eBPF program on cpumap

Extend xdp_redirect_cpu_{usr,kern}.c adding the possibility to load
a XDP program on cpumap entries. The following options have been added:
- mprog-name: cpumap entry program name
- mprog-filename: cpumap entry program filename
- redirect-device: output interface if the cpumap program performs a
  XDP_REDIRECT to an egress interface
- redirect-map: bpf map used to perform XDP_REDIRECT to an egress
  interface
- mprog-disable: disable loading XDP program on cpumap entries

Add xdp_pass, xdp_drop, xdp_redirect stats accounting

Subject: selftest: Add tests for XDP programs in CPUMAP entries

Similar to what have been done for DEVMAP, introduce tests to verify
ability to add a XDP program to an entry in a CPUMAP.
Verify CPUMAP programs can not be attached to devices as a normal
XDP program, and only programs with BPF_XDP_CPUMAP attach type can
be loaded in a CPUMAP.

Subject: net: fec: initialize clock with 0 rather than current kernel time

Initializing with 0 makes it much easier to identify time stamps from
otherwise uninitialized clock.

Initialization of PTP clock with current kernel time makes little sense as
PTP time scale differs from UTC time scale that kernel time represents.
It only leads to confusion when no actual PTP initialization happens, as
these time scales differ in a small integer number of seconds (37 at the
time of writing.)

Subject: af_packet: TPACKET_V3: replace busy-wait loop

A busy-wait loop is used to implement waiting for bits to be copied
from the skb to the kernel buffer before retiring a block. This is
a problem on PREEMPT_RT because the copying task could be preempted
by the busy-waiting task and thus live lock in the busy-wait loop.

Replace the busy-wait logic with an rwlock_t. This provides lockdep
coverage and makes the code RT ready.

Subject: bpf: revert "test_bpf: Flag tests that cannot be jited on s390"

This reverts commit 3203c9010060 ("test_bpf: flag tests that cannot
be jited on s390").

The s390 bpf JIT previously had a restriction on the maximum program
size, which required some tests in test_bpf to be flagged as expected
failures. The program size limitation has been removed, and the tests
now pass, so these tests should no longer be flagged.

Subject: selftests/bpf: Fix possible hang in sockopt_inherit

Andrii reported that sockopt_inherit occasionally hangs up on 5.5 kernel [0].
This can happen if server_thread runs faster than the main thread.
In that case, pthread_cond_wait will wait forever because
pthread_cond_signal was executed before the main thread was blocking.
Let's move pthread_mutex_lock up a bit to make sure server_thread
runs strictly after the main thread goes to sleep.

(Not sure why this is 5.5 specific, maybe scheduling is less
deterministic? But I was able to confirm that it does indeed
happen in a VM.)

Subject: net: mscc: ocelot: rethink Kconfig dependencies again

Having the users of MSCC_OCELOT_SWITCH_LIB depend on REGMAP_MMIO was a
bad idea, since that symbol is not user-selectable. So we should have
kept a 'select REGMAP_MMIO'.

When we do that, we run into 2 more problems:

- By depending on GENERIC_PHY, we are causing a recursive dependency.
  But it looks like GENERIC_PHY has no other dependencies, and other
  drivers select it, so we can select it too:

drivers/of/Kconfig:69:error: recursive dependency detected!
drivers/of/Kconfig:69:  symbol OF_IRQ depends on IRQ_DOMAIN
kernel/irq/Kconfig:68:  symbol IRQ_DOMAIN is selected by REGMAP
drivers/base/regmap/Kconfig:7:  symbol REGMAP default is visible depending on REGMAP_MMIO
drivers/base/regmap/Kconfig:39: symbol REGMAP_MMIO is selected by MSCC_OCELOT_SWITCH_LIB
drivers/net/ethernet/mscc/Kconfig:15:   symbol MSCC_OCELOT_SWITCH_LIB is selected by MSCC_OCELOT_SWITCH
drivers/net/ethernet/mscc/Kconfig:22:   symbol MSCC_OCELOT_SWITCH depends on GENERIC_PHY
drivers/phy/Kconfig:8:  symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3
drivers/phy/broadcom/Kconfig:41:        symbol PHY_BCM_NS_USB3 depends on MDIO_BUS
drivers/net/phy/Kconfig:13:     symbol MDIO_BUS depends on MDIO_DEVICE
drivers/net/phy/Kconfig:6:      symbol MDIO_DEVICE is selected by PHYLIB
drivers/net/phy/Kconfig:254:    symbol PHYLIB is selected by ARC_EMAC_CORE
drivers/net/ethernet/arc/Kconfig:19:    symbol ARC_EMAC_CORE is selected by ARC_EMAC
drivers/net/ethernet/arc/Kconfig:25:    symbol ARC_EMAC depends on OF_IRQ

- By depending on PHYLIB, we are causing a recursive dependency. PHYLIB
  only has a single dependency, "depends on NETDEVICES", which we are
  already depending on, so we can again hack our way into conformance by
  turning the PHYLIB dependency into a select.

drivers/of/Kconfig:69:error: recursive dependency detected!

Subject: net/mlx5e: Fix missing switch_id for representors

Cited commit in fixes tag missed to set the switch id of the PF and VF
ports. Due to this flow cannot be offloaded, a simple command like below
fails to offload with below error.

tc filter add dev ens2f0np0 parent ffff: prio 1 flower \
 dst_mac 00:00:00:00:00:00/00:00:00:00:00:00 skip_sw \
 action mirred egress redirect dev ens2f0np0pf0vf0

Error: mlx5_core: devices are not on same switch HW, can't offload forwarding.

Hence, fix it by setting switch id for each PF and VF representors port
as before the cited commit.

Subject: net/mlx5: Make MLX5_EN_TLS non-prompt

TLS runs only over Eth, and the Eth driver is the only user of
the core TLS functionality.
There is no meaning of having the core functionality without the usage
in Eth driver.
Hence, let both TLS core implementations depend on MLX5_CORE_EN,
and select MLX5_EN_TLS.

Subject: net/mlx5: E-switch, Avoid function change handler for non ECPF

for non ECPF eswitch manager function, vports are already
enabled/disabled when eswitch is enabled/disabled respectively.
Simplify function change handler for such eswitch manager function.

Therefore, ECPF is the only one which remains PF/VF function change
handler.

Currently only ECPF allows enabling eswitch when SR-IOV is disabled.

Enable PF also to enable eswitch when SR-IOV is disabled.
Load VF vports when eswitch is already enabled.

Subject: net/mlx5: Accel, Add core IPsec support for the Connect-X family

This to set the base for downstream patches to support
the new IPsec implementation of the Connect-X family.

Following modifications made:
- Remove accel layer dependency from MLX5_FPGA_IPSEC.
- Introduce accel_ipsec_ops, each IPsec device will
  have to support these ops.

From 2d64663cd55972d3915a9efb8d7087e1aeeda17e Mon Sep 17 00:00:00 2001
From: Raed Salem <raeds@mellanox.com>

Subject: net/mlx5: IPsec: Add HW crypto offload support

This patch adds support for Connect-X IPsec crypto offload
by implementing the IPsec acceleration layer needed routines,
which delegates IPsec offloads to Connect-X routines.

In Connect-X IPsec, a Security Association (SA) is added or deleted
via allocating a HW context of an encryption/decryption key and
a HW context of a matching SA (IPsec object).
The Security Policy (SP) is added or deleted by creating matching Tx/Rx
steering rules whith an action of encryption/decryption respectively,
executed using the previously allocated SA HW context.

When new xfrm state (SA) is added:
- Use a separate crypto key HW context.
- Create a separate IPsec context in HW to inlcude the SA properties:
 - aes-gcm salt.
 - ICV properties (ICV length, implicit IV).
 - on supported devices also update ESN.
 - associate the allocated crypto key with this IPsec context.

Introduce a new compilation flag MLX5_IPSEC for it.

Downstream patches will implement the Rx,Tx steering
and will add the update esn.

Subject: net/mlx5e: IPsec: Add IPsec steering in local NIC RX

Introduce decrypt FT, the RX error FT and the default rules.

The IPsec RX decrypt flow table is pointed by the TTC
(Traffic Type Classifier) ESP steering rules.
The decrypt flow table has two flow groups. The first flow group
keeps the decrypt steering rule programmed via the "ip xfrm s" interface.
The second flow group has a default rule to forward all non-offloaded
ESP packet to the TTC ESP default RSS TIR.

The RX error flow table is the destination of the decrypt steering rules
in the IPsec RX decrypt flow table. It has a fixed rule with single
copy action that copies ipsec_syndrome to metadata_regB[0:6]. The IPsec
syndrome is used to filter out non-ipsec packet and to return the IPsec
crypto offload status in Rx flow. The destination of RX error flow table
is the TTC ESP default RSS TIR.

All the FTs (decrypt FT and error FT) are created only when IPsec SAs

Subject: net/mlx5e: IPsec: Add Connect-X IPsec Rx data path offload

On receive flow inspect received packets for IPsec offload indication
using the cqe, for IPsec offloaded packets propagate offload status
and stack handle to stack for further processing.

Supported statuses:
- Offload ok.
- Authentication failure.
- Bad trailer indication.

Connect-X IPsec does not use mlx5e_ipsec_handle_rx_cqe.

For RX only offload, we see the BW gain. Below is the iperf3
performance report on two server of 24 cores Intel(R) Xeon(R)
CPU E5-2620 v3 @ 2.40GHz with ConnectX6-DX.
We use one thread per IPsec tunnel.

---------------------------------------------------------------------
Mode          |  Num tunnel | BW     | Send CPU util | Recv CPU util
              |             | (Gbps) | (Average %)   | (Average %)
---------------------------------------------------------------------
Cryto offload | 1           | 4.6    | 4.2           | 14.5
---------------------------------------------------------------------
Cryto offload | 24          | 38     | 73            | 63
---------------------------------------------------------------------
Non-offload   | 1           | 4      | 4             | 13
---------------------------------------------------------------------
Non-offload   | 24          | 23     | 52            | 67

Subject: net/mlx5e: CT: Map 128 bits labels to 32 bit map ID

The 128 bits ct_label field is matched using a 32 bit hardware register.
As such, only the lower 32 bits of ct_label field are offloaded. Change
this logic to support setting and matching higher bits too.
Map the 128 bits data to a unique 32 bits ID. Matching is done as exact
match of the mapping ID of key & mask.

Subject: net: sched: Do not drop root lock in tcf_qevent_handle()

Mirred currently does not mix well with blocks executed after the qdisc
root lock is taken. This includes classification blocks (such as in PRIO,
ETS, DRR qdiscs) and qevents. The locking caused by the packet mirrored by
mirred can cause deadlocks: either when the thread of execution attempts to
take the lock a second time, or when two threads end up waiting on each
other's locks.

The qevent patchset attempted to not introduce further badness of this
sort, and dropped the lock before executing the qevent block. However this
lead to too little locking and races between qdisc configuration and packet
enqueue in the RED qdisc.

Before the deadlock issues are solved in a way that can be applied across
many qdiscs reasonably easily, do for qevents what is done for the
classification blocks and just keep holding the root lock.

Subject: xfrm: interface: use IS_REACHABLE to avoid some compile errors

kernel test robot reported some compile errors:

  ia64-linux-ld: net/xfrm/xfrm_interface.o: in function `xfrmi4_fini':
  net/xfrm/xfrm_interface.c:900: undefined reference to `xfrm4_tunnel_deregister'
  ia64-linux-ld: net/xfrm/xfrm_interface.c:901: undefined reference to `xfrm4_tunnel_deregister'
  ia64-linux-ld: net/xfrm/xfrm_interface.o: in function `xfrmi4_init':

  ia64-linux-ld: net/xfrm/xfrm_interface.c:876: undefined reference to `xfrm4_tunnel_register'
  ia64-linux-ld: net/xfrm/xfrm_interface.c:885: undefined reference to `xfrm4_tunnel_deregister'

This happened when set CONFIG_XFRM_INTERFACE=y and CONFIG_INET_TUNNEL=m.
We don't really want xfrm_interface to depend inet_tunnel completely,
but only to disable the tunnel code when inet_tunnel is not seen.

So instead of adding "select INET_TUNNEL" for XFRM_INTERFACE, this patch
is only to change to IS_REACHABLE to avoid these compile error.

Subject: net: phy: continue searching for C45 MMDs even if first returned
 ffff:ffff

At the time of introduction, in commit bdeced75b13f ("net: dsa: felix:
Add PCS operations for PHYLINK"), support for the Lynx PCS inside Felix
was relying, for USXGMII support, on the fact that get_phy_device() is
able to parse the Lynx PCS "device-in-package" registers for this C45
MDIO device and identify it correctly.

However, this was actually working somewhat by mistake (in the sense
that, even though it was detected, it was detected for the wrong
reasons).

The get_phy_c45_ids() function works by iterating through all MMDs
starting from 1 (MDIO_MMD_PMAPMD) and stops at the first one which
returns a non-zero value in the "device-in-package" register pair,
proceeding to see what that non-zero value is.

For the Felix PCS, the first MMD (1, for the PMA/PMD) returns a non-zero
value of 0xffffffff in the "device-in-package" registers. There is a
code branch which is supposed to treat this case and flag it as wrong,
and normally, this would have caught my attention when adding initial
support for this PCS:

	if ((devs_in_pkg & 0x1fffffff) == 0x1fffffff) {
		/* If mostly Fs, there is no device there, then let's probe
		 * MMD 0, as some 10G PHYs have zero Devices In package,
		 * e.g. Cortina CS4315/CS4340 PHY.
		 */

However, this code never actually kicked in, it seems, because this
snippet from get_phy_c45_devs_in_pkg() was basically sabotaging itself,
by returning 0xfffffffe instead of 0xffffffff:

	/* Bit 0 doesn't represent a device, it indicates c22 regs presence */
	*devices_in_package &= ~BIT(0);

Then the rest of the code just carried on thinking "ok, MMD 1 (PMA/PMD)
says that there are 31 devices in that package, each having a device id
of ffff:ffff, that's perfectly fine, let's go ahead and probe this PHY
device".

But after cleanup commit 320ed3bf9000 ("net: phy: split
devices_in_package"), this got "fixed", and now devs_in_pkg is no longer
0xfffffffe, but 0xffffffff. So now, get_phy_device is returning -ENODEV
for the Lynx PCS, because the semantics have remained mostly unchanged:
the loop stops at the first MMD that returns a non-zero value, and that
is MMD 1.

But the Lynx PCS is simply a clause 37 PCS which implements the required
MAC-side functionality for USXGMII (when operated in C45 mode, which is
where C45 devices-in-package detection is relevant to). Of course it
will fail the PMD/PMA test (MMD 1), since it is not a PHY. But it does
implement detection for MDIO_MMD_PCS (3):

- MDIO_DEVS1=0x008a, MDIO_DEVS2=0x0000,
- MDIO_DEVID1=0x0083, MDIO_DEVID2=0xe400

Let get_phy_c45_ids() continue searching for valid MMDs, and don't
assume that every phy_device has a PMA/PMD MMD implemented.

Subject: net: phy: sfp: Cotsworks SFF module EEPROM fixup

Some Cotsworks SFF have invalid data in the first few bytes of the
module EEPROM.  This results in these modules not being detected as
valid modules.

Address this by poking the correct EEPROM values into the module
EEPROM when the model/PN match and the existing module EEPROM contents
are not correct.

Subject: net: openvswitch: reorder masks array based on usage

This patch reorders the masks array every 4 seconds based on their
usage count. This greatly reduces the masks per packet hit, and
hence the overall performance. Especially in the OVS/OVN case for
OpenShift.

Here are some results from the OVS/OVN OpenShift test, which use
8 pods, each pod having 512 uperf connections, each connection
sends a 64-byte request and gets a 1024-byte response (TCP).
All uperf clients are on 1 worker node while all uperf servers are
on the other worker node.

Kernel without this patch     :  7.71 Gbps
Kernel with this patch applied: 14.52 Gbps

We also run some tests to verify the rebalance activity does not
lower the flow insertion rate, which does not.

usbnet_cdc_update_filter was getting the interface number from the
usb_interface struct in cdc_state->control. However, cdc_ncm does
not initialize that structure in its bind function, but uses
cdc_ncm_ctx instead. Getting intf directly from struct usbnet solves
the problem.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cdc_ncm driver overrides the net_device_ops structure used by usbnet
to be able to hook into .ndo_change_mtu. However, the structure was
missing the .ndo_set_rx_mode field, preventing the driver from
hooking into usbnet's set_rx_mode. This patch adds the missing callback to
usbnet_set_rx_mode in net_device_ops.

Subject: mptcp: silence warning in subflow_data_ready()

since commit d47a72152097 ("mptcp: fix race in subflow_data_ready()"), it
is possible to observe a regression in MP_JOIN kselftests. For sockets in
TCP_CLOSE state, it's not sufficient to just wake up the main socket: we
also need to ensure that received data are made available to the reader.
Silence the WARN_ON_ONCE() in these cases: it preserves the syzkaller fix
and restores kselftests	when they are ran as follows:

  # while true; do
  > make KBUILD_OUTPUT=/tmp/kselftest TARGETS=net/mptcp kselftest
  > done

Reported-by: Florian Westphal <fw@strlen.de>
Fixes: d47a72152097 ("mptcp: fix race in subflow_data_ready()")

Subject: net: sun: cassini: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'cas_tx_tiny_alloc()', GFP_KERNEL can be used
because a few lines below in its only caller, 'cas_alloc_rxds()', is also
called. This function makes an explicit use of GFP_KERNEL.

When memory is allocated in 'cas_init_one()', GFP_KERNEL can be used
because it is a probe function and no lock is acquired.

Subject: tcp: fix segment accounting when DSACK range covers multiple segments

Currently, while processing DSACK, we assume DSACK covers only one
segment. This leads to significant underestimation of DSACKs with
LRO/GRO. This patch fixes segment accounting with DSACK by estimating
segment count from DSACK sequence range / MSS.

Subject: tcp: add SNMP counter for no. of duplicate segments reported by DSACK

There are two existing SNMP counters, TCPDSACKRecv and TCPDSACKOfoRecv,
which are incremented depending on whether the DSACKed range is below
the cumulative ACK sequence number or not. Unfortunately, these both
implicitly assume each DSACK covers only one segment. This makes these
counters unusable for estimating spurious retransmit rates,
or real/non-spurious loss rate.

This patch introduces a new SNMP counter, TCPDSACKRecvSegs, which tracks
the estimated number of duplicate segments based on:
(DSACKed sequence range) / MSS. This counter is usable for estimating
spurious retransmit rates, or real/non-spurious loss rate.

Subject: net: sungem: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'gem_init_one()', GFP_KERNEL can be used
because it is a probe function and no lock is acquired.

From f4079e5d72ff973a8c2937e7aa9fc463dc6bcaa2 Mon Sep 17 00:00:00 2001

Subject: net: alteon: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'ace_allocate_descriptors()' and
'ace_init()' GFP_KERNEL can be used because both functions are called from
the probe function and no lock is acquired.

Subject: net: alteon: Avoid some useless memset

Avoid a memset after a call to 'dma_alloc_coherent()'.
This is useless since
commit 518a2f1925c3 ("dma-mapping: zero memory returned from dma_alloc_*")

Replace a kmalloc+memset with a corresponding kzalloc.

Subject: net: bnxt: don't complain if TC flower can't be supported

The fact that NETIF_F_HW_TC is not set should be a sufficient
indication to the user that TC offloads are not supported.
No need to bother users of older firmware versions with
pointless warnings on every boot.

Also, since the support is optional, bnxt_init_tc() should not
return an error in case FW is old, similarly to how error
is not returned when CONFIG_BNXT_FLOWER_OFFLOAD is not set.

With that we can add an error message to the caller, to warn
about actual unexpected failures.

 name

This patch aligns the return value of hw_atl_utils_ver_match function with
its name.
Change the return type to bool, because it's better aligned with the actual
usage. Return true when the version matches, false otherwise.

Subject: net: atlantic: add support for FW 4.x

This patch adds support for FW 4.x, which is about to get into the
production for some products.
4.x is mostly compatible with 3.x, save for soft reset, which requires
the acquisition of 2 additional semaphores.
Other differences (e.g. absence of PTP support) are handled via
capabilities.

Note: 4.x targets specific products only. 3.x is still the main firmware
branch, which should be used by most users (at least for now).

Subject: bpf, netns: Handle multiple link attachments

Extend the BPF netns link callbacks to rebuild (grow/shrink) or update the
prog_array at given position when link gets attached/updated/released.

This let's us lift the limit of having just one link attached for the new
attach type introduced by subsequent patch.

No functional changes intended.

From e9ddbb7707ff5891616240026062b8c1e29864ca Mon Sep 17 00:00:00 2001
From: Jakub Sitnicki <jakub@cloudflare.com>
Date: Fri, 17 Jul 2020 12:35:23 +0200
Subject: bpf: Introduce SK_LOOKUP program type with a dedicated attach point

Add a new program type BPF_PROG_TYPE_SK_LOOKUP with a dedicated attach type
BPF_SK_LOOKUP. The new program kind is to be invoked by the transport layer
when looking up a listening socket for a new connection request for
connection oriented protocols, or when looking up an unconnected socket for
a packet for connection-less protocols.

When called, SK_LOOKUP BPF program can select a socket that will receive
the packet. This serves as a mechanism to overcome the limits of what
bind() API allows to express. Two use-cases driving this work are:

 (1) steer packets destined to an IP range, on fixed port to a socket

     192.0.2.0/24, port 80 -> NGINX socket

 (2) steer packets destined to an IP address, on any port to a socket

     198.51.100.1, any port -> L7 proxy socket

In its run-time context program receives information about the packet that
triggered the socket lookup. Namely IP version, L4 protocol identifier, and
address 4-tuple. Context can be further extended to include ingress
interface identifier.

To select a socket BPF program fetches it from a map holding socket
references, like SOCKMAP or SOCKHASH, and calls bpf_sk_assign(ctx, sk, ...)
helper to record the selection. Transport layer then uses the selected
socket as a result of socket lookup.

In its basic form, SK_LOOKUP acts as a filter and hence must return either
SK_PASS or SK_DROP. If the program returns with SK_PASS, transport should
look for a socket to receive the packet, or use the one selected by the
program if available, while SK_DROP informs the transport layer that the
lookup should fail.

This patch only enables the user to attach an SK_LOOKUP program to a
network namespace. Subsequent patches hook it up to run on local delivery
path in ipv4 and ipv6 stacks.

Subject: inet: Run SK_LOOKUP BPF program on socket lookup

Run a BPF program before looking up a listening socket on the receive path.
Program selects a listening socket to yield as result of socket lookup by
calling bpf_sk_assign() helper and returning SK_PASS code. Program can
revert its decision by assigning a NULL socket with bpf_sk_assign().

Alternatively, BPF program can also fail the lookup by returning with
SK_DROP, or let the lookup continue as usual with SK_PASS on return, when
no socket has been selected with bpf_sk_assign().

This lets the user match packets with listening sockets freely at the last
possible point on the receive path, where we know that packets are destined
for local delivery after undergoing policing, filtering, and routing.

With BPF code selecting the socket, directing packets destined to an IP
range or to a port range to a single socket becomes possible.

In case multiple programs are attached, they are run in series in the order
in which they were attached. The end result is determined from return codes
of all the programs according to following rules:

 1. If any program returned SK_PASS and selected a valid socket, the socket
    is used as result of socket lookup.
 2. If more than one program returned SK_PASS and selected a socket,
    last selection takes effect.
 3. If any program returned SK_DROP, and no program returned SK_PASS and
    selected a socket, socket lookup fails with -ECONNREFUSED.
 4. If all programs returned SK_PASS and none of them selected a socket,
    socket lookup continues to htable-based lookup.

Subject: udp: Run SK_LOOKUP BPF program on socket lookup

Following INET/TCP socket lookup changes, modify UDP socket lookup to let
BPF program select a receiving socket before searching for a socket by
destination address and port as usual.

Lookup of connected sockets that match packet 4-tuple is unaffected by this
change. BPF program runs, and potentially overrides the lookup result, only
if a 4-tuple match was not found.

Subject: tools/bpftool: Add name mappings for SK_LOOKUP prog and attach type

Make bpftool show human-friendly identifiers for newly introduced program
and attach type, BPF_PROG_TYPE_SK_LOOKUP and BPF_SK_LOOKUP, respectively.

Also, add the new prog type bash-completion, man page and help message.

Subject: selftests/bpf: Tests for BPF_SK_LOOKUP attach point

Add tests to test_progs that exercise:

 - attaching/detaching/querying programs to BPF_SK_LOOKUP hook,
 - redirecting socket lookup to a socket selected by BPF program,
 - failing a socket lookup on BPF program's request,
 - error scenarios for selecting a socket from BPF program,
 - accessing BPF program context,
 - attaching and running multiple BPF programs.

Run log:

Subject: net: phy: add USXGMII link partner ability constants

The constants are taken from the USXGMII Singleport Copper Interface

Subject: net: enetc: Initialize SerDes for SGMII and USXGMII protocols

ENETC has ethernet MACs capable of SGMII, 2500BaseX and USXGMII. But in
order to use these protocols some SerDes configurations need to be
performed. The SerDes is configurable via an internal PCS PHY which is
connected to an internal MDIO bus at address 0.

This patch basically removes the dependency on bootloader regarding
SerDes initialization.

Subject: net: enetc: Use DT protocol information to set up the ports

Use DT information rather than in-band information from bootloader to
set up MAC for XGMII. For RGMII use the DT indication in addition to
RGMII defaults in hardware.
However, this implies that PHY connection information needs to be
extracted before netdevice creation, when the ENETC Port MAC is
being configured.

Subject: net: phy: at803x: add mdix configuration support for AR9331 and
 AR8035

This patch add MDIX configuration ability for AR9331 and AR8035. Theoretically
it should work on other Atheros PHYs, but I was able to test only this
two.

Since I have no certified reference HW able to detect or configure MDIX, this
functionality was confirmed by oscilloscope.

Subject: net: remove compat_sock_common_{get,set}sockopt

Add the compat handling to sock_common_{get,set}sockopt instead,
keyed of in_compat_syscall().  This allow to remove the now unused
->compat_{get,set}sockopt methods from struct proto_ops.

From 55db9c0e853421fa71cac5e6855898601f78a1f5 Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@lst.de>
Date: Fri, 17 Jul 2020 08:23:15 +0200
Subject: net: remove compat_sys_{get,set}sockopt

Now that the ->compat_{get,set}sockopt proto_ops methods are gone
there is no good reason left to keep the compat syscalls separate.

This fixes the odd use of unsigned int for the compat_setsockopt
optlen and the missing sock_use_custom_sol_socket.

It would also easily allow running the eBPF hooks for the compat
syscalls, but such a large change in behavior does not belong into
a consolidation patch like this one.

Subject: netfilter: remove the compat_{get,set} methods

All instances handle compat sockopts via in_compat_syscall() now, so
remove the compat_{get,set} methods as well as the
compat_nf_{get,set}sockopt wrappers.

From a44d9e72100f7044ac46e4e6dc475f5b4097830f Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@lst.de>
Date: Fri, 17 Jul 2020 08:23:31 +0200
Subject: net: make ->{get,set}sockopt in proto_ops optional

Just check for a NULL method instead of wiring up
sock_no_{get,set}sockopt.

Subject: sctp: copy the optval from user space in sctp_setsockopt

Prepare for for moving the copy_from_user from the individual sockopts
to the main setsockopt helper.  As of this commit the kopt variable
is not used yet, but the following commits will start using it.

Subject: sctp: pass a kernel pointer to sctp_setsockopt_bindx

Rename sctp_setsockopt_bindx_kernel back to sctp_setsockopt_bindx,
and use the kernel pointer that sctp_setsockopt has available instead of
directly handling the user pointer in the old sctp_setsockopt_bindx.

From: Willem de Bruijn <willemb@google.com>

Subject: icmp: support rfc 4884

Add setsockopt SOL_IP/IP_RECVERR_4884 to return the offset to an
extension struct if present.

ICMP messages may include an extension structure after the original
datagram. RFC 4884 standardized this behavior. It stores the offset
in words to the extension header in u8 icmphdr.un.reserved[1].

The field is valid only for ICMP types destination unreachable, time
exceeded and parameter problem, if length is at least 128 bytes and
entire packet does not exceed 576 bytes.

Return the offset to the start of the extension struct when reading an
ICMP error from the error queue, if it matches the above constraints.

Do not return the raw u8 field. Return the offset from the start of
the user buffer, in bytes. The kernel does not return the network and
transport headers, so subtract those.

Also validate the headers. Return the offset regardless of validation,
as an invalid extension must still not be misinterpreted as part of
the original datagram. Note that !invalid does not imply valid. If
the extension version does not match, no validation can take place,
for instance.

For backward compatibility, make this optional, set by setsockopt
SOL_IP/IP_RECVERR_RFC4884. For API example and feature test, see
github.com/wdebruij/kerneltools/blob/master/tests/recv_icmp_v2.c

For forward compatibility, reserve only setsockopt value 1, leaving
other bits for additional icmp extensions.

Changes
  v1->v2:
  - convert word offset to byte offset from start of user buffer
    - return in ee_data as u8 may be insufficient
  - define extension struct and object header structs
  - return len only if constraints met
  - if returning len, also validate

Subject: ptp: add ability to configure duty cycle for periodic output

There are external event timestampers (PHCs with support for
PTP_EXTTS_REQUEST) that timestamp both event edges.

When those edges are very close (such as in the case of a short pulse),
there is a chance that the collected timestamp might be of the rising,
or of the falling edge, we never know.

There are also PHCs capable of generating periodic output with a
configurable duty cycle. This is good news, because we can space the
rising and falling edge out enough in time, that the risks to overrun
the 1-entry timestamp FIFO of the extts PHC are lower (example: the
perout PHC can be configured for a period of 1 second, and an "on" time
of 0.5 seconds, resulting in a duty cycle of 50%).

A flag is introduced for signaling that an on time is present in the
perout request structure, for preserving compatibility. Logically
speaking, the duty cycle cannot exceed 100% and the PTP core checks for
this.

PHC drivers that don't support this flag emit a periodic output of an
unspecified duty cycle, same as before.

The duty cycle is encoded as an "on" time, similar to the "start" and
"period" times, and reuses the reserved space while preserving overall
binary layout.

Pahole reported before:

struct ptp_perout_request {
        struct ptp_clock_time start;                     /*     0    16 */
        struct ptp_clock_time period;                    /*    16    16 */
        unsigned int               index;                /*    32     4 */
        unsigned int               flags;                /*    36     4 */
        unsigned int               rsv[4];               /*    40    16 */

        /* size: 56, cachelines: 1, members: 5 */
        /* last cacheline: 56 bytes */
};

And now:

struct ptp_perout_request {
        struct ptp_clock_time start;                     /*     0    16 */
        struct ptp_clock_time period;                    /*    16    16 */
        unsigned int               index;                /*    32     4 */
        unsigned int               flags;                /*    36     4 */
        union {
                struct ptp_clock_time on;                /*    40    16 */
                unsigned int       rsv[4];               /*    40    16 */
        };                                               /*    40    16 */

        /* size: 56, cachelines: 1, members: 5 */
        /* last cacheline: 56 bytes */
};

Subject: ptp: introduce a phase offset in the periodic output request

Some PHCs like the ocelot/felix switch cannot emit generic periodic
output, but just PPS (pulse per second) signals, which:
- don't start from arbitrary absolute times, but are rather
  phase-aligned to the beginning of [the closest next] second.
- have an optional phase offset relative to that beginning of the
  second.

For those, it was initially established that they should reject any
other absolute time for the PTP_PEROUT_REQUEST than 0.000000000 [1].

But when it actually came to writing an application [2] that makes use
of this functionality, we realized that we can't really deal generically
with PHCs that support absolute start time, and with PHCs that don't,
without an explicit interface. Namely, in an ideal world, PHC drivers
would ensure that the "perout.start" value written to hardware will
result in a functional output. This means that if the PTP time has
become in the past of this PHC's current time, it should be
automatically fast-forwarded by the driver into a close enough future
time that is known to work (note: this is necessary only if the hardware
doesn't do this fast-forward by itself). But we don't really know what
is the status for PHC drivers in use today, so in the general sense,
user space would be risking to have a non-functional periodic output if
it simply asked for a start time of 0.000000000.

So let's introduce a flag for this type of reduced-functionality
hardware, named PTP_PEROUT_PHASE. The start time is just "soon", the
only thing we know for sure about this signal is that its rising edge
events, Rn, occur at:

Rn = perout.phase + n * perout.period

The "phase" in the periodic output structure is simply an alias to the
"start" time, since both cannot logically be specified at the same time.
Therefore, the binary layout of the structure is not affected.

Subject: net: mscc: ocelot: add support for PTP waveform configuration

For PPS output (perout period is 1.000000000), accept the new "phase"
parameter from the periodic output request structure.

For both PPS and freeform output, accept the new "on" argument for
specifying the duty cycle of the generated signal. Preserve the old
defaults for this "on" time: 1 us for PPS, and half the period for
freeform output.

Also preserve the old behavior that accepted the "phase" via the "start"
argument.

Subject: net: dsa: Setup dsa_netdev_ops

Now that we have all the infrastructure in place for calling into the
dsa_ptr->netdev_ops function pointers, install them when we configure
the DSA CPU/management interface and tear them down. The flow is
unchanged from before, but now we preserve equality of tests when
network device drivers do tests like dev->netdev_ops == &foo_ops which
was not the case before since we were allocating an entirely new
structure.

Subject: net: macb: WoL support for GEM type of Ethernet controller

Adapt the Wake-on-Lan feature to the Cadence GEM Ethernet controller.
This controller has different register layout and cannot be handled by
previous code.
We disable completely interrupts on all the queues but the queue 0.
Handling of WoL interrupt is done in another interrupt handler
positioned depending on the controller version used, just between
suspend() and resume() calls.
It allows to lower pressure on the generic interrupt hot path by
removing the need to handle 2 tests for each IRQ: the first figuring out
the controller revision, the second for actually knowing if the WoL bit
is set.

Queue management in suspend()/resume() functions inspired from RFC patch
by Harini Katakam <harinik@xilinx.com>, thanks!

Subject: arch, net: remove the last csum_partial_copy() leftovers

Most of the tree only uses and implements csum_partial_copy_nocheck,
but the c6x and lib/checksum.c implement a csum_partial_copy that
isn't used anywere except to define csum_partial_copy.  Get rid of
this pointless alias.

Subject: net: packetengines: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'hamachi_init_one()' (hamachi.c), GFP_KERNEL
can be used because it is a probe function and no lock is acquired.

When memory is allocated in 'yellowfin_init_one()' (yellowfin.c),
GFP_KERNEL can be used because it is a probe function and no lock is
acquired.

Subject: qed, qede, qedf: convert link mode from u32 to ETHTOOL_LINK_MODE

Currently qed driver already ran out of 32 bits to store link modes,
and this doesn't allow to add and support more speeds.
Convert custom link mode to generic Ethtool bitmap and definitions
(convenient Phylink shorthands are used for elegance and readability).
This allowed us to drop all conversions/mappings between the driver
and Ethtool.

This involves changes in qede and qedf as well, as they used definitions
from shared "qed_if.h".

Subject: qede: populate supported link modes maps on module init

Simplify and lighten qede_set_link_ksettings() by declaring static link
modes maps and populating them on module init. This way we save plenty
of text size at the low expense of __ro_after_init and __initconst data
(the latter will be purged after module init is done).

Subject: qed: use transceiver data to fill link partner's advertising speeds

Currently qed driver does not take into consideration transceiver's
capabilities when generating link partner's speed advertisement. This
leads to e.g. incorrect ethtool link info on 10GbaseT modules.
Use transceiver info not only for advertisement and support arrays, but
also for link partner's abilities to fix it.

Misc: fix a couple of comments nearby.

Subject: qed: remove unused qed_hw_info::port_mode and QED_PORT_MODE

Struct field qed_hw_info::port_mode isn't used anywhere in the code, so
can be safely removed to prevent possible dead code addition.
Also remove the enumeration QED_PORT_MODE orphaned after this deletion.

Subject: qed: populate supported link modes maps on module init

Simplify and lighten qed_set_link() by declaring static link modes maps
and populating them on module init. This way we save plenty of text size
at the low expense of __ro_after_init and __initconst data (the latter
will be purged after module init is done).

Misc: sanitize exit callback.

From 99785a87fc7d27207c7dca0f0fe04386f1981690 Mon Sep 17 00:00:00 2001
From: Alexander Lobakin <alobakin@marvell.com>
Date: Mon, 20 Jul 2020 21:08:15 +0300
Subject: qed: add support for the extended speed and FEC modes

Add all necessary code (NVM parsing, MFW and Ethtool reports etc.) to
support extended speed and FEC modes.
These new modes are supported by the new boards revisions and newer
MFW versions.

Misc: correct port type for MEDIA_KR.

Subject: ethernet: myri10ge: use generic power management

Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.

With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.

This driver makes use of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(),
pci_set_power_state() and pci_set_master() to do required operations. In
generic mode, they are no longer needed.

Change function parameter in both .suspend() and .resume() to
"struct device*" type. Use to_pci_dev() and dev_get_drvdata() to get
"struct pci_dev*" variable and drv data.

Compile-tested only.

Subject: testptp: promote 'perout' variable to int64_t

Since 'perout' holds the nanosecond value of the signal's period, it
should be a 64-bit value. Current assumption is that it cannot be larger
than 1 second.

Subject: testptp: add new options for perout phase and pulse width

Extend the example program for PTP ancillary functionality with the
ability to configure not only the periodic output's period (frequency),
but also the phase and duty cycle (pulse width) which were newly
introduced.

The ioctl level also needs to be updated to the new PTP_PEROUT_REQUEST2,
since the original PTP_PEROUT_REQUEST doesn't support this
functionality. For an in-tree testing program, not having explicit
backwards compatibility is fine, as it should always be tested with the
current kernel headers and sources.

Tested with an oscilloscope on the felix switch PHC:

echo '2 0' > /sys/class/ptp/ptp1/pins/switch_1588_dat0
./testptp -d /dev/ptp1 -p 1000000000 -w 100000000 -H 1000 -i 0

This patch replaces addition assignment operator with a simple assignment

sufficient in both cases and this change simplifies the introduction of
u64_stats_update_* in these functions.

Subject: net: atlantic: use u64_stats_update_* to protect access to 64-bit
 stats

This patch adds u64_stats_update_* usage to protect access to 64-bit stats,
where necessary.

This is necessary for per-ring stats, because they are updated by the
driver directly, so there is a possibility for a partial read.

Other stats require no additional protection, e.g.:
 * all MACSec stats are fetched directly from HW (under semaphore);
 * nic/ndev stats (aq_stats_s) are fetched directly from FW (under mutex).

Subject: net: atlantic: enable ipv6 support for TCP LSO and UDP GSO

This patch enables ipv6 support for TCP LSO and UDP GSO.
The code itself (aq_nic_map_skb) was ready for this after udp gso feature,
but corresponding NETIF_F_TSO6 wasn't enabled.

We now have tested both tcp and udp v6 GSO, and enabling them safely.

Subject: net: atlantic: add hwmon getter for MAC temperature

This patch adds the possibility to obtain MAC temperature via hwmon.
On A1 there are two separate temperature sensors.
On A2 there's only one temperature sensor, which is used for reporting
both MAC and PHY temperature.

Subject: tc-testing: Add tdc to kselftests

Add tdc to existing kselftest infrastructure so that it can be run with
existing kselftests. TDC now generates objects in objdir/kselftest
without cluttering main objdir, leaves source directory clean, and
installs correctly in kselftest_install, properly adding itself to
run_kselftest.sh script.

Add tc-testing as a target of selftests/Makefile. Create tdc.sh to run
tdc.py targets with correct arguments. To support single target from
selftest/Makefile, combine tc-testing/bpf/Makefile and
tc-testing/Makefile. Move action.c up a directory to tc-testing/.

Tested with:
 make O=/tmp/{objdir} TARGETS="tc-testing" kselftest
 cd /tmp/{objdir}
 cd kselftest
 cd tc-testing
 ./tdc.sh

 make -C tools/testing/selftests/ TARGETS=tc-testing run_tests

 make TARGETS="tc-testing" kselftest
 cd tools/testing/selftests
 ./kselftest_install.sh /tmp/exampledir
 My VM doesn't run all the kselftests so I commented out all except my
 target and net/pmtu.sh then:
 cd /tmp/exampledir && ./run_kselftest.sh

Subject: mISDN: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'setup_hw()' (hfcpci.c) GFP_KERNEL can be used
because it is called from the probe function and no lock is taken.
The call chain is:
   hfc_probe()
   --> setup_card()
   --> setup_hw()

When memory is allocated in 'inittiger()' (netjet.c) GFP_ATOMIC must be
used because a spin_lock is taken by the caller (i.e. 'nj_init_card()')
This is also consistent with the other allocations done in the function.

Subject: net: dsa: use the ETH_MIN_MTU and ETH_DATA_LEN default values

Now that DSA supports MTU configuration, undo the effects of commit
8b1efc0f83f1 ("net: remove MTU limits on a few ether_setup callers") and
let DSA interfaces use the default min_mtu and max_mtu specified by
ether_setup(). This is more important for min_mtu: since DSA is
Ethernet, the minimum MTU is the same as of any other Ethernet
interface, and definitely not zero. For the max_mtu, we have a callback
through which drivers can override that, if they want to.

Subject: bpf, netns: Fix build without CONFIG_INET

When CONFIG_NET is set but CONFIG_INET isn't, build fails with:

  ld: kernel/bpf/net_namespace.o: in function `netns_bpf_attach_type_unneed':
  kernel/bpf/net_namespace.c:32: undefined reference to `bpf_sk_lookup_enabled'
  ld: kernel/bpf/net_namespace.o: in function `netns_bpf_attach_type_need':
  kernel/bpf/net_namespace.c:43: undefined reference to `bpf_sk_lookup_enabled'

This is because without CONFIG_INET bpf_sk_lookup_enabled symbol is not
available. Wrap references to bpf_sk_lookup_enabled with preprocessor
conditionals.

Fixes: 1559b4aa1db4 ("inet: Run SK_LOOKUP BPF program on socket lookup")

Subject: mt76: allow more channels, allowed in ETSI domain

While looking at the ETSI regulatory domain definitions
and a patch, which allows more channels for ath10k, I also
checked the channels allowed for mt76.

ETSI regulations would possibly allow to add channels 32, 68,
96, 144, 169 and 173. IEEE 802.11-2016 defines no operating class
for channels 32, 68 and 96. This leaves us channels 144, 169 and 173,
which are included in this patch.

I tested 169 and 173 with a mt76 based USB dongle (AVM AC 860) and they
worked fine. If I saw that right, these channels are also covered by
register definitions inside the driver.

Channel 144 should also work, but gets disabled by the kernel as of now.

Subject: mt76: fix include in pci.h

kernel test robot <lkp@intel.com> found the following issue
and Kalle Valo forwarded it to Linux wireless.

drivers/net/wireless/mediatek/mt76/pci.c:8:6:
warning: no previous prototype for 'mt76_pci_disable_aspm'

Fix this by adding the missing include of mt76.h as Kalle
suggested.

Subject: mt76: mt7915: add a fixed AC queue mapping

In MT7915, hardware queue map is flexible. However, certain firmware modules
like MU and U-APSD presume a fixed queue order to adapt some devices that have
DMA scheduler with a strict order, so this patch can help in the long run.

Subject: mt76: mt7915: add MU-MIMO support

Enable MU-MIMO DL/UL and add relative counters in debugfs.

Currently MU modules read WTBL first to notify BA changes to
other cross modules, so adjust mt7915_mcu_sta_ba() accordingly.

Subject: mt76: mt7615: schedule tx tasklet and sta poll on mac tx free

Unlike on earlier chips, DMA completion on MT7615 does not imply actually
having sent out any packets.
Since AQL will prevent filling the hardware queues and will only allow more
packets to be passed to the driver after tx completion, it makes much more
sense to schedule the tx tasklet there.
This is also needed for scheduling tx in testmode support

Subject: mt76: mt7615: use full on-chip memory address for WF_PHY registers

Now that the bus access functions can use mapping for accessing full
register addresses, use it for WF_PHY registers to keep them constant.
Needed for follow-up work on testmode support

All drivers use this in pretty much the same way. Moving it to core helps with
some checks for the upcoming testmode support

Subject: mt76: add API for testmode support

This can be used for calibration in the manufacturing process.
It supports sending a configurable number of packets with a specific rate
and configurable tx power levels / antenna settings.
It also supports receiving packets and showing some statistics, including
packet counters and detailed RSSI information.
It will only be compiled in if CONFIG_NL80211_TESTMODE is enabled

Subject: mt76: mt7615: avoid polling in fw_own for mt7663

According to the vendor sdk, mt7663 does not need to poll register after
firmware own. Since just mt7622 polls status register, set proper
timeout value according to the vendor sdk

Subject: mt76: mt7615: add mt7615_pm_wake utility routine

Introduce mt7615_pm_wake utility routine to wake the device from
runtime low-power state (lower-power state is currently supported by
offload firmware for pcie devices).

Introduce mt7615_update_survey utility routine in order to compute
survey stats without waking up the device since it runs holding mt76 lock.
Run mt7615_pm_wake directly in mt7615_update_channel since it can run
with mt76.mutex held if called by mac80211

Subject: mt76: mt7615: improve mt7615_driver_own reliability

mt7615_driver_own can fail if it runs too close to mt7615_fw_own. In
order to improve mt7615_driver_own reliability, retry to get runtime-pm
ownership if mt7615_driver_own fails

Subject: mt76: mt7663u: sync probe sampling with rate configuration

On usb device rate configuration for sampling is performed relying on a
workqueue since it is not possible to access the device in the interrupt
context. Move the configuration of the probe_rate flag in the workqueue
in order to keep probe sampling in sync with actual rate configuration

Subject: mt76: mt7915: potential array overflow in mt7915_mcu_tx_rate_report()

Smatch complains that "wcidx" value comes from the network and thus
cannot be trusted.  In this case, it actually seems to come from the
firmware.  If your wireless firmware is malicious then probably no
amount of carefulness can protect you.

On the other hand, these days we still try to check the firmware as much
as possible.  Verifying that the index is within bounds will silence a
static checker warning.  And it's harmless and a good exercise in kernel
hardening.  So I suggest that we do add a bounds check.

Subject: mt76: mt76u: add mt76_skb_adjust_pad utility routine

Introduce mt76_skb_adjust_pad to reuse the code adding sdio support to
mt7615 driver and remove code duplication. Move 4B header configuration
for usb devices out of mt76_skb_adjust_pad

Subject: mt76: mt7615: sdio code must access rate/key regs in preocess context

As usb, sdio relies on mt76 workqueue to configure tx rate or upload
keys to the hw. This is a preliminary patch to add SDIO support to
mt76 driver

Subject: mt76: mt76s: move queue accounting in mt76s_tx_queue_skb

In order to avoid possible overflows, move tx queue accounting from
mt7663s_tx_run_queue() to mt76s_tx_queue_skb_raw()/mt76s_tx_queue_skb()

Subject: s390/bpf: Fix sign extension in branch_ku

Both signed and unsigned variants of BPF_JMP | BPF_K require
sign-extending the immediate. JIT emits cgfi for the signed case,
which is correct, and clgfi for the unsigned case, which is not
correct: clgfi zero-extends the immediate.

s390 does not provide an instruction that does sign-extension and
unsigned comparison at the same time. Therefore, fix by first loading
the sign-extended immediate into work register REG_1 and proceeding
as if it's BPF_X.

Subject: s390/bpf: Tolerate not converging code shrinking

"BPF_MAXINSNS: Maximum possible literals" unnecessarily falls back to
the interpreter because of failing sanity check in bpf_set_addr. The
problem is that there are a lot of branches that can be shrunk, and
doing so opens up the possibility to shrink even more. This process
does not converge after 3 passes, causing code offsets to change during
the codegen pass, which must never happen.

Fix by inserting nops during codegen pass in order to preserve code
offets.

Subject: bpf, riscv: Modify JIT ctx to support compressed instructions

This patch makes the necessary changes to struct rv_jit_context and to
bpf_int_jit_compile to support compressed riscv (RVC) instructions in
the BPF JIT.

It changes the JIT image to be u16 instead of u32, since RVC instructions
are 2 bytes as opposed to 4.

It also changes ctx->offset and ctx->ninsns to refer to 2-byte
instructions rather than 4-byte ones. The riscv PC is required to be
16-bit aligned with or without RVC, so this is sufficient to refer to
any valid riscv offset.

The code for computing jump offsets in bytes is updated accordingly,
and factored into a new "ninsns_rvoff" function to simplify the code.

Subject: s390/bpf: Use bpf_skip() in bpf_jit_prologue()

Now that we have bpf_skip() for emitting nops, use it in
bpf_jit_prologue() in order to reduce code duplication.

Subject: bpf, riscv: Add encodings for compressed instructions

This patch adds functions for encoding and emitting compressed riscv
(RVC) instructions to the BPF JIT.

Some regular riscv instructions can be compressed into an RVC instruction
if the instruction fields meet some requirements. For example, "add rd,
rs1, rs2" can be compressed into "c.add rd, rs2" when rd == rs1.

To make using RVC encodings simpler, this patch also adds helper
functions that selectively emit either a regular instruction or a
compressed instruction if possible.

For example, emit_add will produce a "c.add" if possible and regular
"add" otherwise.

Subject: libbpf bpf_helpers: Use __builtin_offsetof for offsetof

The non-builtin route for offsetof has a dependency on size_t from
stdlib.h/stdint.h that is undeclared and may break targets.
The offsetof macro in bpf_helpers may disable the same macro in other
headers that have a #ifdef offsetof guard. Rather than add additional
dependencies improve the offsetof macro declared here to use the
builtin that is available since llvm 3.7 (the first with a BPF backend).

Subject: bpf, riscv: Use compressed instructions in the rv64 JIT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch uses the RVC support and encodings from bpf_jit.h to optimize
the rv64 jit.

The optimizations work by replacing emit(rv_X(...)) with a call to a
helper function emit_X, which will emit a compressed version of the
instruction when possible, and when RVC is enabled.

The JIT continues to pass all tests in lib/test_bpf.c, and introduces
no new failures to test_verifier; both with and without RVC being enabled.

Most changes are straightforward replacements of emit(rv_X(...), ctx)
with emit_X(..., ctx), with the following exceptions bearing mention;

* Change emit_imm to sign-extend the value in "lower", since the
checks for RVC (and the instructions themselves) treat the value as
signed. Otherwise, small negative immediates will not be recognized as
encodable using an RVC instruction. For example, without this change,
emit_imm(rd, -1, ctx) would cause lower to become 4095, which is not a
6b int even though a "c.li rd, -1" instruction suffices.

* For {BPF_MOV,BPF_ADD} BPF_X, drop using addiw,addw in the 32-bit
cases since the values are zero-extended into the upper 32 bits in
the following instructions anyways, and the addition commutes with
zero-extension. (BPF_SUB BPF_X must still use subw since subtraction
does not commute with zero-extension.)

This patch avoids optimizing branches and jumps to use RVC instructions
since surrounding code often makes assumptions about the sizes of
emitted instructions. Optimizing these will require changing these
functions (e.g., emit_branch) to dynamically compute jump offsets.

The following are examples of the JITed code for the verifier selftest
"direct packet read test#3 for CGROUP_SKB OK", without and with RVC
enabled, respectively. The former uses 178 bytes, and the latter uses 112,
for a ~37% reduction in code size for this example.

Subject: bpf: Compute bpf_skc_to_*() helper socket btf ids at build time

Currently, socket types (struct tcp_sock, udp_sock, etc.)
used by bpf_skc_to_*() helpers are computed when vmlinux_btf
is first built in the kernel.

Commit 5a2798ab32ba
("bpf: Add BTF_ID_LIST/BTF_ID/BTF_ID_UNUSED macros")
implemented a mechanism to compute btf_ids at kernel build
time which can simplify kernel implementation and reduce
runtime overhead by removing in-kernel btf_id calculation.
This patch did exactly this, removing in-kernel btf_id
computation and utilizing build-time btf_id computation.

If CONFIG_DEBUG_INFO_BTF is not defined, BTF_ID_LIST will
define an array with size of 5, which is not enough for
btf_sock_ids. So define its own static array if
CONFIG_DEBUG_INFO_BTF is not defined.

Sync kernel header btf_ids.h to tools directory.
Also define macro CONFIG_DEBUG_INFO_BTF before
including btf_ids.h in prog_tests/resolve_btfids.c
since non-stub definitions for BTF_ID_LIST etc. macros
are defined under CONFIG_DEBUG_INFO_BTF. This
prevented test_progs from failing.

Subject: bpf: Add BTF_ID_LIST_GLOBAL in btf_ids.h

Existing BTF_ID_LIST used a local static variable
to store btf_ids. This patch provided a new macro
BTF_ID_LIST_GLOBAL to store btf_ids in a global
variable which can be shared among multiple files.

The existing BTF_ID_LIST is still retained.
Two reasons. First, BTF_ID_LIST is also used to build
btf_ids for helper arguments which typically
is an array of 5. Since typically different
helpers have different signature, it makes
little sense to share them. Second, some
current computed btf_ids are indeed local.
If later those btf_ids are shared between
different files, they can use BTF_ID_LIST_GLOBAL then.

Subject: bpf: Make btf_sock_ids global

tcp and udp bpf_iter can reuse some socket ids in
btf_sock_ids, so make it global.

I put the extern definition in btf_ids.h as a central
place so it can be easily discovered by developers.

Subject: selftests/bpf: Fix test_lwt_seg6local.sh hangs

OpenBSD netcat (Debian patchlevel 1.195-2) does not seem to react to
SIGINT for whatever reason, causing prefix.pl to hang after
test_lwt_seg6local.sh exits due to netcat inheriting
test_lwt_seg6local.sh's file descriptors.

Fix by using SIGTERM instead.

Subject: bpf: net: Use precomputed btf_id for bpf iterators

One additional field btf_id is added to struct
bpf_ctx_arg_aux to store the precomputed btf_ids.
The btf_id is computed at build time with
BTF_ID_LIST or BTF_ID_LIST_GLOBAL macro definitions.
All existing bpf iterators are changed to used
pre-compute btf_ids.

From e4d9c2320716ea0e9ef59f503ddd8f253a642ddd Mon Sep 17 00:00:00 2001
From: Ilya Leoshkevich <iii@linux.ibm.com>
Date: Mon, 20 Jul 2020 13:48:06 +0200
Subject: samples/bpf, selftests/bpf: Use bpf_probe_read_kernel

A handful of samples and selftests fail to build on s390, because
after commit 0ebeea8ca8a4 ("bpf: Restrict bpf_probe_read{, str}()
only to archs where they work") bpf_probe_read is not available
anymore.

Fix by using bpf_probe_read_kernel.

From 9165e1d70fb34ce438e78aad90408cfa86e4c2d0 Mon Sep 17 00:00:00 2001
From: Tony Ambardar <tony.ambardar@gmail.com>

Subject: bpftool: Use only nftw for file tree parsing

The bpftool sources include code to walk file trees, but use multiple
frameworks to do so: nftw and fts. While nftw conforms to POSIX/SUSv3 and
is widely available, fts is not conformant and less common, especially on
non-glibc systems. The inconsistent framework usage hampers maintenance
and portability of bpftool, in particular for embedded systems.

Standardize code usage by rewriting one fts-based function to use nftw and
clean up some related function warnings by extending use of "const char *"
arguments. This change helps in building bpftool against musl for OpenWrt.

Also fix an unsafe call to dirname() by duplicating the string to pass,
since some implementations may directly alter it. The same approach is
used in libbpf.c.

Subject: enetc: Refine buffer descriptor ring sizes

It's time to differentiate between Rx and Tx ring sizes.
Not only Tx rings are processed differently than Rx rings,
but their default number also differs - i.e. up to 8 Tx rings
per device (8 traffic classes) vs. 2 Rx rings (one per CPU).
So let's set Tx rings sizes to half the size of the Rx rings
for now, to be conservative.
The default ring sizes were decreased as well (to the next
lower power of 2), to reduce the memory footprint, buffering
etc., since the measurements I've made so far show that the
rings are very unlikely to get full.
This change also anticipates the introduction of the
dynamic interrupt moderation (dim) algorithm which operates
on maximum packet thresholds of 256 packets for Rx and 128
packets for Tx.

Subject: enetc: Factor out the traffic start/stop procedures

A reliable traffic pause (and reconfiguration) procedure
is needed to be able to safely make h/w configuration
changes during run-time, like changing the mode in which the
interrupts are operating (i.e. with or without coalescing),
as opposed to making on-the-fly register updates that
may be subject to h/w or s/w concurrency issues.
To this end, the code responsible of the run-time device
configurations that basically starts resp. stops the traffic
flow through the device has been extracted from the
the enetc_open/_close procedures, to the separate standalone
enetc_start/_stop procedures. Traffic stop should be as
graceful as possible, it lets the executing napi threads to
to finish while the interrupts stay disabled.  But since
the napi thread will try to re-enable interrupts by clearing
the device's unmask register, the enable_irq/ disable_irq
API has been used to avoid this potential concurrency issue
and make the traffic pause procedure more reliable.

Subject: enetc: Add interrupt coalescing support

Enable programming of the interrupt coalescing registers
and allow manual configuration of the coalescing time
thresholds via ethtool.  Packet thresholds have been fixed
to predetermined values as there's no point in making them
run-time configurable, also anticipating the dynamic interrupt
moderation (DIM) algorithm which uses fixed packet thresholds
as well.  If the interface is up when the operation mode of
traffic interrupt events is changed by the user (i.e. switching
from default per-packet interrupts to coalesced interrupts),
the traffic needs to be paused in the process.
This patch also prepares the ground for introducing DIM on Rx.

Subject: enetc: Add adaptive interrupt coalescing

Use the generic dynamic interrupt moderation (dim)
framework to implement adaptive interrupt coalescing
on Rx.  With the per-packet interrupt scheme, a high
interrupt rate has been noted for moderate traffic flows
leading to high CPU utilization.  The 'dim' scheme
implemented by the current patch addresses this issue
improving CPU utilization while using minimal coalescing
time thresholds in order to preserve a good latency.
On the Tx side use an optimal time threshold value by
default.  This value has been optimized for Tx TCP
streams at a rate of around 85kpps on a 1G link,
at which rate half of the Tx ring size (128) gets filled
in 1500 usecs.  Scaling this down to 2.5G links yields
the current value of 600 usecs, which is conservative
and gives good enough results for 1G links too (see
next).

Below are some measurement results for before and after
this patch (and related dependencies) basically, for a
2 ARM Cortex-A72 @1.3Ghz CPUs system (32 KB L1 data cache),
using 60secs log netperf TCP stream tests @ 1Gbit link
(maximum throughput):

1) 1 Rx TCP flow, both Rx and Tx processed by the same NAPI
thread on the same CPU:
	CPU utilization		int rate (ints/sec)
Before:	50%-60% (over 50%)		92k
After:  13%-22%				3.5k-12k
Comment:  Major CPU utilization improvement for a single flow
	  Rx TCP flow (i.e. netperf -t TCP_MAERTS) on a single
	  CPU. Usually settles under 16% for longer tests.

2) 4 Rx TCP flows + 4 Tx TCP flows (+ pings to check the latency):
	Total CPU utilization	Total int rate (ints/sec)
Before:	~80% (spikes to 90%)		~100k
After:   60% (more steady)		  ~4k
Comment:  Important improvement for this load test, while the
	  ping test outcome does not show any notable
	  difference compared to before.

Subject: net: phylink: update ethtool reporting for fixed-link modes

Comparing the ethtool output from phylink and non-phylink fixed-link
setups shows that we have some differences:

- The "auto-negotiation" fields are different; phylink reports these
  as "No", non-phylink reports these as "Yes" for the supported and
  advertising masks.
- The link partner advertisement is set to the link speed with non-
  phylink, but phylink leaves this unset, causing all link partner
  fields to be omitted.

The phylink ethtool output also disagrees with the software emulated
PHY dump via the MII registers.

Update the phylink fixed-link parsing code so that we better reflect
the behaviour of the non-phylink code that this facility replaces, and
bring the ethtool interface more into line with the report from via the
MII interface.

Subject: net: phylink: rearrange resolve mac_config() call

Use a boolean to indicate whether mac_config() should be called during
a resolution. This allows resolution to have a single location where
mac_config() will be called, which will allow us to make decisions
about how and what we do.

Subject: net: phylink: ensure link is down when changing interface

The only PHYs that are used with phylink which change their interface
are the BCM84881 and MV88X3310 family, both of which only change their
interface modes on link-up events.  However, rather than relying upon
this behaviour by the PHY, we should give a stronger guarantee when
resolving that the link will be down whenever we change the interface
mode.  This patch implements that stronger guarantee for resolve.

Subject: net: phylink: simplify phy case for ksettings_set method

When we have a PHY attached, an ethtool ksettings_set() call only
really needs to call through to the phylib equivalent; phylib will
call back to us when the link changes so we can update our state.
Therefore, we can bypass most of our ksettings_set() call for this
case.

Subject: net: phylink: simplify fixed-link case for ksettings_set method

For fixed links, we only allow the current settings, so this should be
a matter of merely rejecting an attempt to change the settings.  If the
settings agree, then there is nothing more we need to do.

Subject: net: phylink: in-band pause mode advertisement update for PCS

Re-code the pause in-band advertisement update in light of the addition
of PCS support, so that we perform the minimum required; only the PCS
configuration function needs to be called in this case, followed by the
request to trigger a restart of negotiation if the programmed
advertisement changed.

We need to change the pcs_config() signature to pass whether resolved
pause should be passed to the MAC for setups such as mvneta and mvpp2
where doing so overrides the MAC manual flow controls.

Subject: net: phylink: re-implement interface configuration with PCS

With PCS support, how we implement interface reconfiguration (or other
major reconfiguration) is not up to the job; we end up reconfiguring
the PCS for an interface change while the link could potentially be up.
In order to solve this, add two additional MAC methods for major
configuration, one to prepare for the change, and one to finish the
change.

This allows mvneta and mvpp2 to shutdown what they require prior to the
MAC and PCS configuration calls, and then restart as appropriate.

This impacts ksettings_set(), which now needs to identify whether the
change is a minor tweak to the advertisement masks or whether the
interface mode has changed, and call the appropriate function for that
update.

Subject: net: phylink: add struct phylink_pcs

Add a way for MAC PCS to have private data while keeping independence
from struct phylink_config, which is used for the MAC itself. We need
this independence as we will have stand-alone code for PCS that is
independent of the MAC.  Introduce struct phylink_pcs, which is
designed to be embedded in a driver private data structure.

This structure does not include a mdio_device as there are PCS
implementations such as the Marvell DSA and network drivers where this
is not necessary.

Subject: net: ena: avoid unnecessary rearming of interrupt vector when
 busy-polling

For an overview of the race created by this patch goto synchronization
label.

In napi busy-poll mode, the kernel invokes the napi handler of the
device repeatedly to poll the NIC's receive queues. This process
repeats until a timeout, specific for each connection, is up.
By polling packets in busy-poll mode the user may gain lower latency
and higher throughput (since the kernel no longer waits for interrupts
to poll the queues) in expense of CPU usage.

Upon completing a napi routine, the driver checks whether
the routine was called by an interrupt handler. If so, the driver
re-enables interrupts for the device. This is needed since an
interrupt routine invocation disables future invocations until
explicitly re-enabled.

The driver avoids re-enabling the interrupts if they were not disabled
in the first place (e.g. if driver in busy mode).
Originally, the driver checked whether interrupt re-enabling is needed
by reading the 'ena_napi->unmask_interrupt' variable. This atomic
variable was set upon interrupt and cleared after re-enabling it.

In the 4.10 Linux version, the 'napi_complete_done' call was changed
so that it returns 'false' when device should not re-enable
interrupts, and 'true' otherwise. The change includes reading the
"NAPIF_STATE_IN_BUSY_POLL" flag to check if the napi call is in
busy-poll mode, and if so, return 'false'.
The driver was changed to re-enable interrupts according to this
routine's return value.
The Linux community rejected the use of the
'ena_napi->unmaunmask_interrupt' variable to determine whether
unmasking is needed, and urged to use napi_napi_complete_done()
return value solely.
See https://lore.kernel.org/patchwork/patch/741149/ for more details

As explained, a busy-poll session exists for a specified timeout
value, after which it exits the busy-poll mode and re-enters it later.
This leads to many invocations of the napi handler where
napi_complete_done() false indicates that interrupts should be
re-enabled.
This creates a bug in which the interrupts are re-enabled
unnecessarily.
To reproduce this bug:
    1) echo 50 | sudo tee /proc/sys/net/core/busy_poll
    2) echo 50 | sudo tee /proc/sys/net/core/busy_read
    3) Add counters that check whether
    'ena_unmask_interrupt(tx_ring, rx_ring);'
    is called without disabling the interrupts in the first
    place (i.e. with calling the interrupt routine
    ena_intr_msix_io())

Steps 1+2 enable busy-poll as the default mode for new connections.

The busy poll routine rearms the interrupts after every session by
design, and so we need to add an extra check that the interrupts were
masked in the first place.

synchronization:
This patch introduces a race between the interrupt handler
ena_intr_msix_io() and the napi routine ena_io_poll().
Some macros and instruction were added to prevent this race from leaving
the interrupts masked. The following specifies the different race
scenarios in this patch:

1) interrupt handler and napi routine run sequentially
    i) interrupt handler is called, sets 'interrupts_masked' flag and
	successfully schedules the napi handler via softirq.

    In this scenario the napi routine might not see the flag change
    for several reasons:
	a) The flag is stored in a register by the compiler. For this
	case the WRITE_ONCE macro which prevents this.
	b) The compiler might reorder the instruction. For this the
	smp_wmb() instruction was used which implies a compiler memory
	barrier.
	c) On archs with weak consistency model (like ARM64) the napi
	routine might be scheduled and start running before the flag
	STORE instruction is committed to cache/memory. To ensure this
	doesn't happen, the smp_wmb() instruction was added. It ensures
	that the flag set instruction is committed before scheduling
	napi.

    ii) compiler reorders the flag's value check in the 'if' with
    the flag set in the napi routine.

    This scenario is prevented by smp_rmb() call after the flag check.

2) interrupt handler and napi routine run in parallel (can happen when
busy poll routine invokes the napi handler)

    i) interrupt handler sets the flag in one core, while the napi
    routine reads it in another core.

    This scenario also is divided into two cases:
	a) napi_complete_done() doesn't finish running, in which case
	napi_sched() would just set NAPIF_STATE_MISSED and the napi
	routine would reschedule itself without changing the flag's value.

	b) napi_complete_done() finishes running. In this case the
	napi routine might override the flag's value.
	This doesn't present any rise since it later unmasks the
	interrupt vector.

Subject: net: ena: cosmetic: change ena_com_stats_admin stats to u64

The size of the admin statistics in ena_com_stats_admin is changed
from 32bit to 64bit so to align with the sizes of the other statistics
in the driver (i.e. rx_stats, tx_stats and ena_stats_dev).

This is done as part of an effort to create a unified API to read
statistics.

Subject: net: ena: add support for traffic mirroring

Add support for traffic mirroring, where the hardware reads the
buffer from the instance memory directly.

Traffic Mirroring needs access to the rx buffers in the instance.
To have this access, this patch:
1. Changes the code to map and unmap the rx buffers bidirectionally.
2. Enables the relevant bit in driver_supported_features to indicate
   to the FW that this driver supports traffic mirroring.

Rx completion is not generated until mirroring is done to avoid
the situation where the driver changes the buffer before it is
mirrored.

Subject: net: ena: enable support of rss hash key and function changes

Add the rss_configurable_function_key bit to driver_supported_feature.

This bit tells the device that the driver in question supports the
retrieving and updating of RSS function and hash key, and therefore
the device should allow RSS function and key manipulation.

This commit turns on  device support for hash key and RSS function
management. Without this commit this feature is turned off at the
device and appears to the user as unsupported.

This commit concludes the following series of already merged commits:
commit 0af3c4e2eab8 ("net: ena: changes to RSS hash key allocation")
commit c1bd17e51c71 ("net: ena: change default RSS hash function to Toeplitz")
commit f66c2ea3b18a ("net: ena: allow setting the hash function without changing the key")
commit e9a1de378dd4 ("net: ena: fix error returning in ena_com_get_hash_function()")
commit 80f8443fcdaa ("net: ena: avoid unnecessary admin command when RSS function set fails")
commit 6a4f7dc82d1e ("net: ena: rss: do not allocate key when not supported")
commit 0d1c3de7b8c7 ("net: ena: fix incorrect default RSS key")

The above commits represent the last part of the implementation of
this feature, and with them merged the feature can be enabled
in the device.

Subject: net: ena: move llq configuration from ena_probe to ena_device_init()

When the ENA device resets to recover from some error state, all LLQ
configuration values are reset to their defaults, because LLQ is
initialized only once during ena_probe().

Changes in this commit:
1. Move the LLQ configuration process into ena_init_device()
which is called from both ena_probe() and ena_restore_device(). This
way, LLQ setup configurations that are different from the default
values will survive resets.

2. Extract the LLQ bar mapping to ena_map_llq_bar(),
and call once in the lifetime of the driver from ena_probe(),
since there is no need to unmap and map the LLQ bar again every reset.

3. Map the LLQ bar if it exists, regardless if initialization of LLQ
placement policy (ENA_ADMIN_PLACEMENT_POLICY_DEV) succeeded
or not. Initialization might fail the first time, falling back to the
ENA_ADMIN_PLACEMENT_POLICY_HOST placement policy, but later succeed
after device reset, in which case the LLQ bar needs to be mapped
already.

Subject: net: ena: support new LLQ acceleration mode

New devices add a new hardware acceleration engine, which adds some
restrictions to the driver.
Metadata descriptor must be present for each packet and the maximum
burst size between two doorbells is now limited to a number
advertised by the device.

This patch adds:
1. A handshake protocol between the driver and the device, so the
device will enable the accelerated queues only when both sides
support it.

2. The driver support for the new acceleration engine:
2.1. Send metadata descriptor for each Tx packet.
2.2. Limit the number of packets sent between doorbells.(*)

(*) A previous driver implementation of this feature was comitted in
commit 05d62ca218f8 ("net: ena: add handling of llq max tx burst size")
however the design of the interface between the driver and device
changed since then. This change is reflected in this commit.

Subject: ipvs: queue delayed work to expire no destination connections if
 expire_nodest_conn=1

When expire_nodest_conn=1 and a destination is deleted, IPVS does not
expire the existing connections until the next matching incoming packet.
If there are many connection entries from a single client to a single
destination, many packets may get dropped before all the connections are
expired (more likely with lots of UDP traffic). An optimization can be
made where upon deletion of a destination, IPVS queues up delayed work
to immediately expire any connections with a deleted destination. This
ensures any reused source ports from a client (within the IPVS timeouts)
are scheduled to new real servers instead of silently dropped.

Subject: netfilter: Use fallthrough pseudo-keyword

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Move the setup done for MQPRIO into a separate function so that
with the addition of another offload we do not crowd
dpaa2_eth_setup_tc(). After this restructuring it's easier to see what
is supported in terms of Qdisc offloading.

Subject: dpaa2-eth: add support for TBF offload

React to TC_SETUP_QDISC_TBF and configure the egress shaper as
appropriate with the maximum rate and burst size requested by the user.
TBF can only be offloaded on DPAA2 when it's the root qdisc, ie it's a
per port shaper.

Subject: bareudp: Reverted support to enable & disable rx metadata collection

The commit fe80536acf83 ("bareudp: Added attribute to enable & disable
rx metadata collection") breaks the the original(5.7) default behavior of
bareudp module to collect RX metadadata at the receive. It was added to
avoid the crash at the kernel neighbour subsytem when packet with metadata
from bareudp is processed. But it is no more needed as the
commit 394de110a733 ("net: Added pointer check for
dst->ops->neigh_lookup in dst_neigh_lookup_skb") solves this crash.

Fixes: fe80536acf83 ("bareudp: Added attribute to enable & disable rx metadata collection")

Subject: ionic: get MTU from lif identity

Change from using hardcoded MTU limits and instead use the
firmware defined limits. The value from the LIF attributes is
the frame size, so we take off the header size to convert to
MTU size.

Subject: ionic: set netdev default name

If the host system's udev fails to set a new name for the
network port, there is no NETDEV_CHANGENAME event to trigger
the driver to send the name down to the firmware.  It is safe
to set the lif name multiple times, so we add a call early on
to set the default netdev name to be sure the FW has something
to use in its internal debug logging.  Then when udev gets
around to changing it we can update it to the actual name the
system will be using.

Subject: net: mscc: ocelot: fix non-initialized CPU port on VSC7514

The VSC7514 is marketed as a 10-port switch, however it has 11 physical
ports (0->10) in the block diagram:
https://www.microsemi.com/product-directory/ethernet-switches/3992-vsc7514
(also in the device tree at arch/mips/boot/dts/mscc/ocelot.dtsi)

Additionally, by architecture it has one more entry in the analyzer
block, situated right after the physical ports, for the CPU port module.
This is not a physical port, it only represents a channel for frame
injection and extraction. That entry for the CPU port is at index 11 in
the analyzer.

When the register groups for QSYS_SWITCH_PORT_MODE, SYS_PORT_MODE and
SYS_PAUSE_CFG are declared to be replicated 11 times, the 11th entry in
the array of regfields is not initialized, so the CPU port module is not
initialized either.

The documentation of QSYS_SWITCH_PORT_MODE for VSC7514 also says that
this register group is replicated 12 times, so this patch is simply
reflecting that and not introducing any further inconsistency.

Fixes: 886e1387c73d ("net: mscc: ocelot: convert QSYS_SWITCH_PORT_MODE and SYS_PORT_MODE to regfields")
Fixes: 541132f0961a ("net: mscc: ocelot: convert SYS_PAUSE_CFG register access to regfield")

Subject: dt-bindings: net: dsa: Let dsa.txt refer to dsa.yaml

The DSA bindings have been converted to YAML. Therefore, the old text style
documentation should refer to that one.

The text file can be removed completely once all the existing DSA switch
bindings have been converted as well.

 Distributed Switch Architecture Device Tree Bindings
 ----------------------------------------------------
 
-Switches are true Linux devices and can be probed by any means. Once
-probed, they register to the DSA framework, passing a node
-pointer. This node is expected to fulfil the following binding, and
-may contain additional properties as required by the device it is
-embedded within.
-
-Required properties:
-
-- ports		: A container for child nodes representing switch ports.
-
-Optional properties:
-
-- dsa,member	: A two element list indicates which DSA cluster, and position
-		  within the cluster a switch takes. <0 0> is cluster 0,
-		  switch 0. <0 1> is cluster 0, switch 1. <1 0> is cluster 1,
-		  switch 0. A switch not part of any cluster (single device
-		  hanging off a CPU port) must not specify this property
-
-The ports container has the following properties
-
-Required properties:
-
-- #address-cells	: Must be 1
-- #size-cells		: Must be 0
-
-Each port children node must have the following mandatory properties:
-- reg			: Describes the port address in the switch
-
-An uplink/downlink port between switches in the cluster has the following
-mandatory property:
-
-- link			: Should be a list of phandles to other switch's DSA
-			  port. This port is used as the outgoing port
-			  towards the phandle ports. The full routing
-			  information must be given, not just the one hop
-			  routes to neighbouring switches.
-
-A CPU port has the following mandatory property:
-
-- ethernet		: Should be a phandle to a valid Ethernet device node.
-                          This host device is what the switch port is
-			  connected to.
-
-A user port has the following optional property:
-
-- label			: Describes the label associated with this port, which
-                          will become the netdev name.
-
-Port child nodes may also contain the following optional standardised
-properties, described in binding documents:
-
-- phy-handle		: Phandle to a PHY on an MDIO bus. See
-			  Documentation/devicetree/bindings/net/ethernet.txt
-			  for details.
-
-- phy-mode		: See
-			  Documentation/devicetree/bindings/net/ethernet.txt
-			  for details.
-
-- fixed-link		: Fixed-link subnode describing a link to a non-MDIO
-			  managed entity. See
-			  Documentation/devicetree/bindings/net/fixed-link.txt
-			  for details.
-
-The MAC address will be determined using the optional properties
-defined in ethernet.txt.
-
-Example
-
-The following example shows three switches on three MDIO busses,
-linked into one DSA cluster.
-
-&mdio1 {
-	#address-cells = <1>;
-	#size-cells = <0>;

Subject: net: dccp: Add SIOCOUTQ IOCTL support (send buffer fill)

This adds support for the SIOCOUTQ IOCTL to get the send buffer fill
of a DCCP socket, like UDP and TCP sockets already have.

Regarding the used data field: DCCP uses per packet sequence numbers,
not per byte, so sequence numbers can't be used like in TCP. sk_wmem_queued
is not used by DCCP and always 0, even in test on highly congested paths.
Therefore this uses sk_wmem_alloc like in UDP.

Subject: net: phy: fix check in get_phy_c45_ids

After the patch below, the iteration through the available MMDs is
completely short-circuited, and devs_in_pkg remains set to the initial
value of zero.

Due to devs_in_pkg being zero, the rest of get_phy_c45_ids() is
short-circuited too: the following loop never reaches below this point
either (it executes "continue" for every device in package, failing to
retrieve PHY ID for any of them):

	/* Now probe Device Identifiers for each device present. */
	for (i = 1; i < num_ids; i++) {
		if (!(devs_in_pkg & (1 << i)))
			continue;

So c45_ids->device_ids remains populated with zeroes. This causes an
Aquantia AQR412 PHY (same as any C45 PHY would, in fact) to be probed by
the Generic PHY driver.

The issue seems to be a case of submitting partially committed work (and
therefore testing something other than was submitted).

The intention of the patch was to delay exiting the loop until one more
condition is reached (the devs_in_pkg read from hardware is either 0, OR
mostly f's). So fix the patch to reflect that.

Tested with traffic on a LS1028A-QDS, the PHY is now probed correctly
using the Aquantia driver. The devs_in_pkg bit field is set to
0xe000009a, and the MMDs that are present have the following IDs:

enetc_imdio_remove() is missing from the enetc_pf_probe()
bailout path. Not surprisingly because enetc_setup_serdes()
is registering the imdio bus for internal purposes, and it's
not obvious that enetc_imdio_remove() currently performs the
teardown of enetc_setup_serdes().
To fix this, define enetc_teardown_serdes() to wrap
enetc_imdio_remove() (improve code maintenance) and call it
on bailout and remove paths.

Subject: hv_netvsc: add support for vlans in AF_PACKET mode

Vlan tagged packets are getting dropped when used with DPDK that uses
the AF_PACKET interface on a hyperV guest.

The packet layer uses the tpacket interface to communicate the vlans
information to the upper layers. On Rx path, these drivers can read the
vlan info from the tpacket header but on the Tx path, this information
is still within the packet frame and requires the paravirtual drivers to
push this back into the NDIS header which is then used by the host OS to
form the packet.

This transition from the packet frame to NDIS header is currently missing
hence causing the host OS to drop the all vlan tagged packets sent by
the drivers that use AF_PACKET (ETH_P_ALL) such as DPDK.

Here is an overview of the changes in the vlan header in the packet path:

The RX path (userspace handles everything):
  1. RX VLAN packet is stripped by HOST OS and placed in NDIS header
  2. Guest Kernel RX hv_netvsc packets and moves VLAN info from NDIS
     header into kernel SKB
  3. Kernel shares packets with user space application with PACKET_MMAP.
     The SKB VLAN info is copied to tpacket layer and indication set
     TP_STATUS_VLAN_VALID.
  4. The user space application will re-insert the VLAN info into the frame

The TX path:
  1. The user space application has the VLAN info in the frame.
  2. Guest kernel gets packets from the application with PACKET_MMAP.
  3. The kernel later sends the frame to the hv_netvsc driver. The only way
     to send VLANs is when the SKB is setup & the VLAN is stripped from the
     frame.
  4. TX VLAN is re-inserted by HOST OS based on the NDIS header. If it sees
     a VLAN in the frame the packet is dropped.

Subject: devlink: Always use user_ptr[0] for devlink and simplify post_doit

Currently devlink instance is searched on all doit() operations.
But it is optionally stored into user_ptr[0]. This requires
rediscovering devlink again doing post_doit().

Few devlink commands related to port shared buffers needs 3 pointers
(devlink, devlink_port, and devlink_sb) while executing doit commands.
Though devlink pointer can be derived from the devlink_port during
post_doit() operation when doit() callback has acquired devlink
instance lock, relying on such scheme to access devlik pointer makes
code very fragile.

Hence, to avoid ambiguity in post_doit() and to avoid searching
devlink instance again, simplify code by always storing devlink
instance in user_ptr[0] and derive devlink_sb pointer in their
respective callback routines.

From b71a61ccfebb4ff733d2d9fc66cd5c75b7ae46a2 Mon Sep 17 00:00:00 2001
From: Tom Parkin <tparkin@katalix.com>
Date: Wed, 22 Jul 2020 17:32:05 +0100
Subject: l2tp: cleanup whitespace use

Fix up various whitespace issues as reported by checkpatch.pl:

 * remove spaces around operators where appropriate,
 * add missing blank lines following declarations,
 * remove multiple blank lines, or trailing blank lines at the end of
   functions.

Subject: l2tp: cleanup comments

Modify some l2tp comments to better adhere to kernel coding style, as
reported by checkpatch.pl.

Add descriptive comments for the l2tp per-net spinlocks to document
their use.

Fix an incorrect comment in l2tp_recv_common:

RFC2661 section 5.4 states that:

"The LNS controls enabling and disabling of sequence numbers by sending a
data message with or without sequence numbers present at any time during
the life of a session."

l2tp handles this correctly in l2tp_recv_common, but the comment around
the code was incorrect and confusing.  Fix up the comment accordingly.

Subject: l2tp: cleanup difficult-to-read line breaks

Some l2tp code had line breaks which made the code more difficult to
read.  These were originally motivated by the 80-character line width
coding guidelines, but were actually a negative from the perspective of
trying to follow the code.

Remove these linebreaks for clearer code, even if we do exceed 80
characters in width in some places.

Subject: l2tp: cleanup suspect code indent

l2tp_core has conditionally compiled code in l2tp_xmit_skb for IPv6
support.  The structure of this code triggered a checkpatch warning
due to incorrect indentation.

Fix up the indentation to address the checkpatch warning.

Subject: l2tp: line-break long function prototypes

In l2tp_core.c both l2tp_tunnel_create and l2tp_session_create take
quite a number of arguments and have a correspondingly long prototype.

This is both quite difficult to scan visually, and triggers checkpatch
warnings.

Add a line break to make these function prototypes more readable.

One-element arrays are being deprecated[1]. Replace the one-element
array with a simple value type 'u8 rsvd'[2], once it seems this is
just a placeholder for alignment.

Zero-initialize chain on qed_chain_free(), so it couldn't be freed
twice and provoke undefined behaviour.

Subject: qed: sanitize PBL chains allocation

PBL chain elements are actually DMA addresses stored in __le64, but
currently their size is hardcoded to 8, and DMA addresses are assigned
via cast to variable-sized dma_addr_t without any bitwise conversions.
Change the type of pbl_virt array to match the actual one, add a new
field to store the size of allocated DMA memory and sanitize elements
assignment.

Misc: give more logic names to the members of qed_chain::pbl_sp embedded
struct.

Subject: qed: move chain initialization inlines next to allocation functions

qed_chain_init*() are used in one file/place on "cold" path only, so they
can be uninlined and moved next to the call sites.

Subject: qed: simplify initialization of the chains with an external PBL

Fill PBL table parameters for chains with an external PBL data earlier on
qed_chain_init_params() rather than on allocation itself. This simplifies
allocation code and allows to extend struct ext_pbl for other chain types.

Subject: qed: simplify chain allocation with init params struct

To simplify qed_chain_alloc() prototype and call sites, introduce struct
qed_chain_init_params to specify chain params, and pass a pointer to
filled struct to the actual qed_chain_alloc() instead of a long list
of separate arguments.

Subject: qed: add support for different page sizes for chains

Extend current infrastructure to store chain page size in a struct
and use it in all functions instead of fixed QED_CHAIN_PAGE_SIZE.
Its value remains the default one, but can be overridden in
qed_chain_init_params before chain allocation.

Subject: qed: introduce qed_chain_get_elem_used{,u32}()

Add reverse-variants of qed_chain_get_elem_left{,u32}() to be able to
know current chain occupation. They will be used in the upcoming qede
XDP_REDIRECT code.
They share most of the logics with the mentioned ones, so were reused
to collapse the latters.

Subject: qede: reformat several structures in "qede.h"

Make the file more readable and easier for adding new fields.

Misc: use IFNAMSIZ and netdev_name() instead of sizeof_field()
and direct net_device::name dereferencing.

From 4c2bacbea1a3d49b836d2554383925bcf453d22c Mon Sep 17 00:00:00 2001
From: Alexander Lobakin <alobakin@marvell.com>
Date: Thu, 23 Jul 2020 01:10:44 +0300
Subject: qede: refactor XDP Tx processing

Current XDP Tx logic is suboptimal and can't be reused for XDP_REDIRECT
path.
Make qede_xdp_{tx_int,xmit}() more universal and effective in general to
allow future expanding.

Misc: use unlikely() hints where appropriate and replace "fallthrough"
comments with pseudo-keywords.

Subject: qede: add .ndo_xdp_xmit() and XDP_REDIRECT support

Add XDP_REDIRECT case handling and the corresponding NDO to support
redirecting XDP frames. This also includes registering driver memory
model (currently order-0 page mode) in BPF subsystem.
The total number of XDP queues is usually 1:1 with Rx ones.

From 205a55f4e65353dd4846547d376a6f85cdda3d04 Mon Sep 17 00:00:00 2001

Subject: sfc: convert to new udp_tunnel infrastructure

Check MC_CMD_DRV_ATTACH_EXT_OUT_FLAG_TRUSTED, before setting
the info, which will hopefully protect us from -EPERM errors
the previous code was gracefully ignoring. Ed reports this
is not the 100% correct bit, but it's the best approximation
we have. Shared code reports the port information back to user
space, so we really want to know what was added and what failed.
Ignoring -EPERM is not an option.

The driver does not call udp_tunnel_get_rx_info(), so its own
management of table state is not really all that problematic,
we can leave it be. This allows the driver to continue with its
copious table syncing, and matching the ports to TX frames,
which it will reportedly do one day.

Leave the feature checking in the callbacks, as the device may
remove the capabilities on reset.

Inline the loop from __efx_ef10_udp_tnl_lookup_port() into
efx_ef10_udp_tnl_has_port(), since it's the only caller now.

With new infra this driver gains port replace - when space frees
up in a full table a new port will be selected for offload.
Plus efx will no longer sleep in an atomic context.

v2:
 - amend the commit message about TRUSTED not being 100%
 - add TUNNEL_ENCAP_UDP_PORT_ENTRY_INVALID to mark unsed
   entries

Currently we do not init the subflow write sequence for
MP_JOIN subflows. This will cause bad mapping being
generated as soon as we will use non backup subflow.

When updating a partially acked data fragment, we
actually corrupt it. This is irrelevant till we send
data on a single subflow, as retransmitted data, if
any are discarded by the peer as duplicate, but it
will cause data corruption as soon as we will start
creating non backup subflows.

Subject: mptcp: mark as fallback even early ones

In the unlikely event of a failure at connect time,
we currently clear the request_mptcp flag - so that
the MPC handshake is not started at all, but the msk
is not explicitly marked as fallback.

This would lead to later insertion of wrong DSS options
in the xmitted packets, in violation of RFC specs and
possibly fooling the peer.

Subject: mptcp: explicitly track the fully established status

Currently accepted msk sockets become established only after
accept() returns the new sk to user-space.

As MP_JOIN request are refused as per RFC spec on non fully
established socket, the above causes mp_join self-tests
instabilities.

This change lets the msk entering the established status
as soon as it receives the 3rd ack and propagates the first
subflow fully established status on the msk socket.

Finally we can change the subflow acceptance condition to
take in account both the sock state and the msk fully
established flag.

Subject: subflow: explicitly check for plain tcp rsk

When syncookie are in use, the TCP stack may feed into
subflow_syn_recv_sock() plain TCP request sockets. We can't
access mptcp_subflow_request_sock-specific fields on such
sockets. Explicitly check the rsk ops to do safe accesses.

tcp_send_active_reset() is more prone to transient errors
(memory allocation or xmit queue full): in stress conditions
the kernel may drop the egress packet, and the client will be
stuck.

Subject: l2tp: cleanup comparisons to NULL

checkpatch warns about comparisons to NULL, e.g.

        CHECK: Comparison to NULL could be written "!rt"
        #474: FILE: net/l2tp/l2tp_ip.c:474:
        +       if (rt == NULL) {

These sort of comparisons are generally clearer and more readable
the way checkpatch suggests, so update l2tp accordingly.

Subject: l2tp: cleanup unnecessary braces in if statements

These checks are all simple and don't benefit from extra braces to
clarify intent.  Remove them for easier-reading code.

Subject: l2tp: check socket address type in l2tp_dfs_seq_tunnel_show

checkpatch warns about indentation and brace balancing around the
conditionally compiled code for AF_INET6 support in
l2tp_dfs_seq_tunnel_show.

By adding another check on the socket address type we can make the code
more readable while removing the checkpatch warning.

Subject: l2tp: cleanup netlink send of tunnel address information

l2tp_nl_tunnel_send has conditionally compiled code to support AF_INET6,
which makes the code difficult to follow and triggers checkpatch
warnings.

Split the code out into functions to handle the AF_INET v.s. AF_INET6
cases, which both improves readability and resolves the checkpatch
warnings.

Subject: l2tp: cleanup netlink tunnel create address handling

When creating an L2TP tunnel using the netlink API, userspace must
either pass a socket FD for the tunnel to use (for managed tunnels),
or specify the tunnel source/destination address (for unmanaged
tunnels).

Since source/destination addresses may be AF_INET or AF_INET6, the l2tp
netlink code has conditionally compiled blocks to support IPv6.

Rather than embedding these directly into l2tp_nl_cmd_tunnel_create
(where it makes the code difficult to read and confuses checkpatch to
boot) split the handling of address-related attributes into a separate
function.

Passing "sizeof(struct blah)" in kzalloc calls is less readable,
potentially prone to future bugs if the type of the pointer is changed,
and triggers checkpatch warnings.

Tweak the kzalloc calls in l2tp which use this form to avoid the
warning.

Subject: cxgb4: add loopback ethtool self-test

In this test, loopback pkt is created and sent on default queue.
The packet goes until the Multi Port Switch (MPS) just before
the MAC and based on the specified channel number, it either
goes outside the wire on one of the physical ports or looped
back to Rx path by MPS. In this case, we're specifying loopback
channel, instead of physical ports, so the packet gets looped
back to Rx path, instead of getting transmitted on the wire.

v3:
- Modify commit message to include test details.
v2:
- Add only loopback self-test.

Subject: ice: refactor ice_discover_caps to avoid need to retry

The ice_discover_caps function is used to read the device and function
capabilities, updating the hardware capabilities structures with
relevant data.

The exact number of capabilities returned by the hardware is unknown
ahead of time. The AdminQ command will report the total number of
capabilities in the return buffer.

The current implementation involves requesting capabilities once,
reading this returned size, and then re-requested with that size.

This isn't really necessary. The firmware interface has a maximum size
of ICE_AQ_MAX_BUF_LEN. Firmware can never return more than
ICE_AQ_MAX_BUF_LEN / sizeof(struct ice_aqc_list_caps_elem) capabilities.

Avoid the retry loop by simply allocating a buffer of size
ICE_AQ_MAX_BUF_LEN. This is significantly simpler than retrying. The
extra allocation isn't a big deal, as it will be released after we
finish parsing the capabilities.

Subject: ice: split ice_parse_caps into separate functions

The ice_parse_caps function is used to convert the capability block data
coming from firmware into a structured format used by other parts of the
code.

The current implementation directly updates the hw->func_caps and
hw->dev_caps structures. It is directly called from within
ice_aq_discover_caps. This causes the discover_caps function to have the
side effect of modifying the HW capability structures, which is not
intuitive.

Split this function into ice_parse_dev_caps and ice_parse_func_caps.
These functions will take a pointer to the dev_caps and func_caps
respectively. Also create an ice_parse_common_caps for sharing the
capability logic that is common to device and function.

Doing so enables a future refactor to allow reading and parsing
capabilities into a local caps structure instead of modifying the
members of the HW structure directly.

Subject: ice: split ice_discover_caps into two functions

Using the new ice_aq_list_caps and ice_parse_(dev|func)_caps functions,
replace ice_discover_caps with two functions that each take a pointer to
the dev_caps and func_caps structures respectively.

This makes the side effect of updating the hw->dev_caps and
hw->func_caps obvious from reading the implementation of the function.
Additionally, it opens the way for enabling reading of device
capabilities outside of the initialization flow. By passing in
a pointer, another caller will be able to read the capabilities without
modifying the HW capabilities structures.

As there are no other callers, it is safe to now remove
ice_aq_discover_caps and ice_parse_caps.

Subject: ice: refactor FC functions

Create a helper function for configuring requested flow control so that it
can be utilized by other functions looking to configure flow control
settings. Utilize the existing helper ice_copy_phy_caps_to_cfg() to copy a
PHY capability to configuration instead duplicating the code for it.

Subject: ice: move auto FEC checks into ice_cfg_phy_fec()

The call to ice_cfg_phy_fec() requires the caller to perform certain
actions before calling it. Instead of imposing these preconditions move
the operations into the function and perform them ourselves.

Also, fix some style issues in nearby touched code.

Subject: net: dsa: stop overriding master's ndo_get_phys_port_name

The purpose of this override is to give the user an indication of what
the number of the CPU port is (in DSA, the CPU port is a hardware
implementation detail and not a network interface capable of traffic).

However, it has always failed (by design) at providing this information
to the user in a reliable fashion.

Prior to commit 3369afba1e46 ("net: Call into DSA netdevice_ops
wrappers"), the behavior was to only override this callback if it was
not provided by the DSA master.

That was its first failure: if the DSA master itself was a DSA port or a
switchdev, then the user would not see the number of the CPU port in
/sys/class/net/eth0/phys_port_name, but the number of the DSA master
port within its respective physical switch.

But that was actually ok in a way. The commit mentioned above changed
that behavior, and now overrides the master's ndo_get_phys_port_name
unconditionally. That comes with problems of its own, which are worse in
a way.

The idea is that it's typical for switchdev users to have udev rules for
consistent interface naming. These are based, among other things, on
the phys_port_name attribute. If we let the DSA switch at the bottom
to start randomly overriding ndo_get_phys_port_name with its own CPU
port, we basically lose any predictability in interface naming, or even
uniqueness, for that matter.

So, there are reasons to let DSA override the master's callback (to
provide a consistent interface, a number which has a clear meaning and
must not be interpreted according to context), and there are reasons to
not let DSA override it (it breaks udev matching for the DSA master).

But, there is an alternative method for users to retrieve the number of
the CPU port of each DSA switch in the system:

  $ devlink port
  pci/0000:00:00.5/0: type eth netdev swp0 flavour physical port 0
  pci/0000:00:00.5/2: type eth netdev swp2 flavour physical port 2
  pci/0000:00:00.5/4: type notset flavour cpu port 4
  spi/spi2.0/0: type eth netdev sw0p0 flavour physical port 0
  spi/spi2.0/1: type eth netdev sw0p1 flavour physical port 1
  spi/spi2.0/2: type eth netdev sw0p2 flavour physical port 2
  spi/spi2.0/4: type notset flavour cpu port 4
  spi/spi2.1/0: type eth netdev sw1p0 flavour physical port 0
  spi/spi2.1/1: type eth netdev sw1p1 flavour physical port 1
  spi/spi2.1/2: type eth netdev sw1p2 flavour physical port 2
  spi/spi2.1/3: type eth netdev sw1p3 flavour physical port 3
  spi/spi2.1/4: type notset flavour cpu port 4

So remove this duplicated, unreliable and troublesome method. From this
patch on, the phys_port_name attribute of the DSA master will only
contain information about itself (if at all). If the users need reliable
information about the CPU port they're probably using devlink anyway.

Subject: ice: restore PHY settings on media insertion

After the transition from no media to media FW will clear the
set-phy-cfg data set by the user. Save initial PHY settings and any
settings later requested by the user and use that data to restore PHY
settings on media insertion. Since PHY configuration is now being stored,
replace calls that were calling FW to get the configuration with the saved
copy.

From: Paul Greenwalt <paul.greenwalt@intel.com>

Subject: ice: add link lenient and default override support

Adds functions to check for link override firmware support and get
the override settings for a port. The previously supported/default link
mode was strict mode.

In strict mode link is configured based on get PHY capabilities PHY types
with media.

Lenient mode is now the default link mode. In lenient mode the link is
configured based on get PHY capabilities PHY types without media. This
allows the user to configure link that the media does not report. Limit the
minimum supported link mode to 25G for devices that support 100G, and 1G
for devices that support less than 100G.

Default override is only supported in lenient mode. If default override
is supported and enabled, then default override values are used for
configuring speed and FEC. Default override provide persistent link
settings in the NVM.

Subject: ice: support Total Port Shutdown on devices that support it

When the Port Disable bit is set in the Link Default Override Mask TLV PFA
module in the NVM, Total Port Shutdown mode is supported and enabled.  In
this mode, the driver should act as if the link-down-on-close ethtool
private flag is always enabled and dis-allow any change to that flag.

Subject: ice: add AQC get link topology handle support

Add AQC get link topology handle support. This is needed to determine
Direct Attach (DA) or backplane media type for PHY types that support
either. Get link topology handle cage node type request can be used to
determine if a cage is present or not. If a cage is present for PHY
types that supports both DA and backplane media type, then the media
type is DA, else the media type is backplane.

Subject: ice: add 1G SGMII PHY type

There isn't a case for 1G SGMII in ice_get_media_type() so add
the handling for it.

Also handle the special case where some direct attach
cables may report that they support 1G SGMII, but
that is erroneous since SGMII is supposed to be a
backplane media type (between a MAC and a PHY). If
the driver doesn't handle this special case then a
user could see the 'Port' in ethtool change from
'Direct attach Copper' to 'Backplane' when they have
forced the speed to 1G, but the cable hasn't changed.

Lastly, change ice_aq_get_phy_caps() to save the
module_type info if the function was called with
ICE_AQC_REPORT_TOPO_CAP. This call uses the media
information to populate the module_type. If no
media is present then the values in module_type
will be 0.

Subject: vrf: Handle CONFIG_SYSCTL not set

Randy reported compile failure when CONFIG_SYSCTL is not set/enabled:

ERROR: modpost: "sysctl_vals" [drivers/net/vrf.ko] undefined!

Fix by splitting out the sysctl init and cleanup into helpers that
can be set to do nothing when CONFIG_SYSCTL is disabled. In addition,
move vrf_strict_mode and vrf_strict_mode_change to above
vrf_shared_table_handler (code move only) and wrap all of it
in the ifdef CONFIG_SYSCTL.

Update the strict mode tests to check for the existence of the
/proc/sys entry.

Fixes: 33306f1aaf82 ("vrf: add sysctl parameter for strict mode")

Subject: net: hyperv: dump TX indirection table to ethtool regs

An imbalanced TX indirection table causes netvsc to have low
performance. This table is created and managed during runtime. To help
better diagnose performance issues caused by imbalanced tables, it needs
make TX indirection tables visible.

Because TX indirection table is driver specified information, so
display it via ethtool register dump.

Subject: net/ipv6: switch ipv6_flowlabel_opt to sockptr_t

Pass a sockptr_t to prepare for set_fs-less handling of the kernel
pointer from bpf-cgroup.

Note that the get case is pretty weird in that it actually copies data
back to userspace from setsockopt.

Subject: net: pass a sockptr_t into ->setsockopt

Rework the remaining setsockopt code to pass a sockptr_t instead of a
plain user pointer.  This removes the last remaining set_fs(KERNEL_DS)
outside of architecture specific code.

Subject: net: optimize the sockptr_t for unified kernel/user address spaces

For architectures like x86 and arm64 we don't need the separate bit to
indicate that a pointer is a kernel pointer as the address spaces are
unified.  That way the sockptr_t can be reduced to a union of two
pointers, which leads to nicer calling conventions.

The only caveat is that we need to check that users don't pass in kernel
address and thus gain access to kernel memory.  Thus the USER_SOCKPTR
helper is replaced with a init_user_sockptr function that does this check
and returns an error if it fails.

Subject: sctp: fix slab-out-of-bounds in SCTP_DELAYED_SACK processing

This sockopt accepts two kinds of parameters, using struct
sctp_sack_info and struct sctp_assoc_value. The mentioned commit didn't
notice an implicit cast from the smaller (latter) struct to the bigger
one (former) when copying the data from the user space, which now leads
to an attempt to write beyond the buffer (because it assumes the storing
buffer is bigger than the parameter itself).

Fix it by allocating a sctp_sack_info on stack and filling it out based
on the small struct for the compat case.

Changelog stole from an earlier patch from Marcelo Ricardo Leitner.

Fixes: ebb25defdc17 ("sctp: pass a kernel pointer to sctp_setsockopt_delayed_ack")

Subject: net: openvswitch: fixes potential deadlock in dp cleanup code

The previous patch introduced a deadlock, this patch fixes it by making
sure the work is canceled without holding the global ovs lock. This is
done by moving the reorder processing one layer up to the netns level.

Fixes: eac87c413bf9 ("net: openvswitch: reorder masks array based on usage")

Subject: icmp: revise rfc4884 tests

1) Only accept packets with original datagram len field >= header len.

The extension header must start after the original datagram headers.
The embedded datagram len field is compared against the 128B minimum
stipulated by RFC 4884. It is unlikely that headers extend beyond
this. But as we know the exact header length, check explicitly.

2) Remove the check that datagram length must be <= 576B.

This is a send constraint. There is no value in testing this on rx.
Within private networks it may be known safe to send larger packets.
Process these packets.

This test was also too lax. It compared original datagram length
rather than entire icmp packet length. The stand-alone fix would be:

  -       if (hlen + skb->len > 576)
  +       if (-skb_network_offset(skb) + skb->len > 576)

Subject: icmp: prepare rfc 4884 for ipv6

The RFC 4884 spec is largely the same between IPv4 and IPv6.
Factor out the IPv4 specific parts in preparation for IPv6 support:

- icmp types supported

- icmp header size, and thus offset to original datagram start

- datagram length field offset in icmp(6)hdr.

- datagram length field word size: 4B for IPv4, 8B for IPv6.

Subject: l2tp: WARN_ON rather than BUG_ON in l2tp_dfs_seq_start

l2tp_dfs_seq_start had a BUG_ON to catch a possible programming error in
l2tp_dfs_seq_open.

Since we can easily bail out of l2tp_dfs_seq_start, prefer to do that
and flag the error with a WARN_ON rather than crashing the kernel.

Subject: l2tp: don't BUG_ON session magic checks in l2tp_ppp

checkpatch advises that WARN_ON and recovery code are preferred over
BUG_ON which crashes the kernel.

l2tp_ppp.c's BUG_ON checks of the l2tp session structure's "magic" field
occur in code paths where it's reasonably easy to recover:

 * In the case of pppol2tp_sock_to_session, we can return NULL and the
   caller will bail out appropriately.  There is no change required to
   any of the callsites of this function since they already handle
   pppol2tp_sock_to_session returning NULL.

 * In the case of pppol2tp_session_destruct we can just avoid
   decrementing the reference count on the suspect session structure.
   In the worst case scenario this results in a memory leak, which is
   preferable to a crash.

Convert these uses of BUG_ON to WARN_ON accordingly.

Subject: l2tp: don't BUG_ON seqfile checks in l2tp_ppp

checkpatch advises that WARN_ON and recovery code are preferred over
BUG_ON which crashes the kernel.

l2tp_ppp has a BUG_ON check of struct seq_file's private pointer in
pppol2tp_seq_start prior to accessing data through that pointer.

Rather than crashing, we can simply bail out early and return NULL in
order to terminate the seq file processing in much the same way as we do
when reaching the end of tunnel/session instances to render.

Retain a WARN_ON to help trace possible bugs in this area.

Subject: l2tp: WARN_ON rather than BUG_ON in l2tp_session_queue_purge

l2tp_session_queue_purge is used during session shutdown to drop any
skbs queued for reordering purposes according to L2TP dataplane rules.

The BUG_ON in this function checks the session magic feather in an
attempt to catch lifetime bugs.

Rather than crashing the kernel with a BUG_ON, we can simply WARN_ON and
refuse to do anything more -- in the worst case this could result in a
leak.  However this is highly unlikely given that the session purge only
occurs from codepaths which have obtained the session by means of a lookup
via. the parent tunnel and which check the session "dead" flag to
protect against shutdown races.

While we're here, have l2tp_session_queue_purge return void rather than
an integer, since neither of the callsites checked the return value.

Subject: l2tp: WARN_ON rather than BUG_ON in l2tp_session_free

l2tp_session_free called BUG_ON if the tunnel magic feather value wasn't
correct.  The intent of this was to catch lifetime bugs; for example
early tunnel free due to incorrect use of reference counts.

Since the tunnel magic feather being wrong indicates either early free
or structure corruption, we can avoid doing more damage by simply
leaving the tunnel structure alone.  If the tunnel refcount isn't
dropped when it should be, the tunnel instance will remain in the
kernel, resulting in the tunnel structure and socket leaking.

Subject: net: dsa: mv88e6xxx: Support jumbo configuration on 6190/6190X

The MV88E6190 and MV88E6190X both support per port jumbo configuration
just like the other GE switches. Install the appropriate ops.

Subject: net: dsa: mv88e6xxx: Use chip-wide max frame size for MTU

Some of the chips in the mv88e6xxx family don't support jumbo
configuration per port. But they do have a chip-wide max frame size that
can be used. Use this to approximate the behaviour of configuring a port
based MTU.

Subject: udp: Don't discard reuseport selection when group has connections

When BPF socket lookup prog selects a socket that belongs to a reuseport
group, and the reuseport group has connected sockets in it, the socket
selected by reuseport will be discarded, and socket returned by BPF socket
lookup will be used instead.

Modify this behavior so that the socket selected by reuseport running after
BPF socket lookup always gets used. Ignore the fact that the reuseport
group might have connections because it is only relevant when scoring
sockets during regular hashtable-based lookup.

Fixes: 72f7e9440e9b ("udp: Run SK_LOOKUP BPF program on socket lookup")
Fixes: 6d4201b1386b ("udp6: Run SK_LOOKUP BPF program on socket lookup")

Subject: bpf: Refactor bpf_iter_reg to have separate seq_info member

There is no functionality change for this patch.
Struct bpf_iter_reg is used to register a bpf_iter target,
which includes information for both prog_load, link_create
and seq_file creation.

This patch puts fields related seq_file creation into
a different structure. This will be useful for map
elements iterator where one iterator covers different
map types and different map types may have different
seq_ops, init/fini private_data function and
private_data size.

Subject: bpf: Refactor to provide aux info to bpf_iter_init_seq_priv_t

This patch refactored target bpf_iter_init_seq_priv_t callback
function to accept additional information. This will be needed
in later patches for map element targets since a particular
map should be passed to traverse elements for that particular
map. In the future, other information may be passed to target
as well, e.g., pid, cgroup id, etc. to customize the iterator.

Subject: selftests/bpf: Test BPF socket lookup and reuseport with connections

Cover the case when BPF socket lookup returns a socket that belongs to a
reuseport group, and the reuseport group contains connected UDP sockets.

Ensure that the presence of connected UDP sockets in reuseport group does
not affect the socket lookup result. Socket selected by reuseport should
always be used as result in such case.

Subject: bpf: Support readonly/readwrite buffers in verifier

Readonly and readwrite buffer register states
are introduced. Totally four states,
PTR_TO_RDONLY_BUF[_OR_NULL] and PTR_TO_RDWR_BUF[_OR_NULL]
are supported. As suggested by their respective
names, PTR_TO_RDONLY_BUF[_OR_NULL] are for
readonly buffers and PTR_TO_RDWR_BUF[_OR_NULL]
for read/write buffers.

These new register states will be used
by later bpf map element iterator.

New register states share some similarity to
PTR_TO_TP_BUFFER as it will calculate accessed buffer
size during verification time. The accessed buffer
size will be later compared to other metrics during
later attach/link_create time.

Similar to reg_state PTR_TO_BTF_ID_OR_NULL in bpf
iterator programs, PTR_TO_RDONLY_BUF_OR_NULL or
PTR_TO_RDWR_BUF_OR_NULL reg_types can be set at
prog->aux->bpf_ctx_arg_aux, and bpf verifier will
retrieve the values during btf_ctx_access().
Later bpf map element iterator implementation
will show how such information will be assigned
during target registeration time.

The verifier is also enhanced such that PTR_TO_RDONLY_BUF
can be passed to ARG_PTR_TO_MEM[_OR_NULL] helper argument, and
PTR_TO_RDWR_BUF can be passed to ARG_PTR_TO_MEM[_OR_NULL] or
ARG_PTR_TO_UNINIT_MEM.

Subject: bpf: Fix pos computation for bpf_iter seq_ops->start()

Currently, the pos pointer in bpf iterator map/task/task_file
seq_ops->start() is always incremented.
This is incorrect. It should be increased only if
*pos is 0 (for SEQ_START_TOKEN) since these start()
function actually returns the first real object.
If *pos is not 0, it merely found the object
based on the state in seq->private, and not really
advancing the *pos. This patch fixed this issue
by only incrementing *pos if it is 0.

Note that the old *pos calculation, although not
correct, does not affect correctness of bpf_iter
as bpf_iter seq_file->read() does not support llseek.

This patch also renamed "mid" in bpf_map iterator
seq_file private data to "map_id" for better clarity.

Fixes: 6086d29def80 ("bpf: Add bpf_map iterator")
Fixes: eaaacd23910f ("bpf: Add task and task/file iterator targets")

Subject: bpf: Implement bpf iterator for map elements

The bpf iterator for map elements are implemented.
The bpf program will receive four parameters:
  bpf_iter_meta *meta: the meta data
  bpf_map *map:        the bpf_map whose elements are traversed
  void *key:           the key of one element
  void *value:         the value of the same element

Here, meta and map pointers are always valid, and
key has register type PTR_TO_RDONLY_BUF_OR_NULL and
value has register type PTR_TO_RDWR_BUF_OR_NULL.
The kernel will track the access range of key and value
during verification time. Later, these values will be compared
against the values in the actual map to ensure all accesses
are within range.

A new field iter_seq_info is added to bpf_map_ops which
is used to add map type specific information, i.e., seq_ops,
init/fini seq_file func and seq_file private data size.
Subsequent patches will have actual implementation
for bpf_map_ops->iter_seq_info.

In user space, BPF_ITER_LINK_MAP_FD needs to be
specified in prog attr->link_create.flags, which indicates
that attr->link_create.target_fd is a map_fd.
The reason for such an explicit flag is for possible
future cases where one bpf iterator may allow more than
one possible customization, e.g., pid and cgroup id for
task_file.

Current kernel internal implementation only allows
the target to register at most one required bpf_iter_link_info.
To support the above case, optional bpf_iter_link_info's
are needed, the target can be extended to register such link
infos, and user provided link_info needs to match one of
target supported ones.

Subject: bpf: Implement bpf iterator for hash maps

The bpf iterators for hash, percpu hash, lru hash
and lru percpu hash are implemented. During link time,
bpf_iter_reg->check_target() will check map type
and ensure the program access key/value region is
within the map defined key/value size limit.

For percpu hash and lru hash maps, the bpf program
will receive values for all cpus. The map element
bpf iterator infrastructure will prepare value
properly before passing the value pointer to the
bpf program.

This patch set supports readonly map keys and
read/write map values. It does not support deleting
map elements, e.g., from hash tables. If there is
a user case for this, the following mechanism can
be used to support map deletion for hashtab, etc.
  - permit a new bpf program return value, e.g., 2,
    to let bpf iterator know the map element should
    be removed.
  - since bucket lock is taken, the map element will be
    queued.
  - once bucket lock is released after all elements under
    this bucket are traversed, all to-be-deleted map
    elements can be deleted.

Subject: bpf: Implement bpf iterator for array maps

The bpf iterators for array and percpu array
are implemented. Similar to hash maps, for percpu
array map, bpf program will receive values
from all cpus.

Subject: bpf: Implement bpf iterator for sock local storage map

The bpf iterator for bpf sock local storage map
is implemented. User space interacts with sock
local storage map with fd as a key and storage value.
In kernel, passing fd to the bpf program does not
really make sense. In this case, the sock itself is
passed to bpf program.

Add map_fd to bpf_iter_attach_opts and flags to
bpf_link_create_opts. Later on, bpftool or selftest
will be able to create a bpf map element iterator
by passing map_fd to the kernel during link
creation time.

Subject: tools/bpftool: Add bpftool support for bpf map element iterator

The optional parameter "map MAP" can be added to "bpftool iter"
command to create a bpf iterator for map elements. For example,
  bpftool iter pin ./prog.o /sys/fs/bpf/p1 map id 333

For map element bpf iterator "map MAP" parameter is required.
Otherwise, bpf link creation will return an error.

Quentin Monnet kindly provided bash-completion implementation
for new "map MAP" option.

+		  Map element bpf iterator requires an additional parameter

 		  User can then *cat PATH* to see the bpf iterator output.

Subject: selftests/bpf: Add test for bpf array map iterators

Two subtests are added.
  $ ./test_progs -n 4
  ...
  #4/20 bpf_array_map:OK
  #4/21 bpf_percpu_array_map:OK
  ...

The bpf_array_map subtest also tested bpf program
changing array element values and send key/value
to user space through bpf_seq_write() interface.

From 7b04d6d60fcfb5b2200ffebb9cfb90927bdfeec7 Mon Sep 17 00:00:00 2001

Subject: bpf: Separate bpf_get_[stack|stackid] for perf events BPF

Calling get_perf_callchain() on perf_events from PEBS entries may cause
unwinder errors. To fix this issue, the callchain is fetched early. Such
perf_events are marked with __PERF_SAMPLE_CALLCHAIN_EARLY.

Similarly, calling bpf_get_[stack|stackid] on perf_events from PEBS may
also cause unwinder errors. To fix this, add separate version of these
two helpers, bpf_get_[stack|stackid]_pe. These two hepers use callchain in
bpf_perf_event_data_kern->data->callchain.

Subject: selftests/bpf: Add a test for out of bound rdonly buf access

If the bpf program contains out of bound access w.r.t. a
particular map key/value size, the verification will be
still okay, e.g., it will be accepted by verifier. But
it will be rejected during link_create time. A test
is added here to ensure link_create failure did happen
if out of bound access happened.

Subject: bpf: Fail PERF_EVENT_IOC_SET_BPF when bpf_get_[stack|stackid] cannot
 work

bpf_get_[stack|stackid] on perf_events with precise_ip uses callchain
attached to perf_sample_data. If this callchain is not presented, do not
allow attaching BPF program that calls bpf_get_[stack|stackid] to this
event.

In the error case, -EPROTO is returned so that libbpf can identify this
error and print proper hint message.

Subject: selftests/bpf: Add test for CGROUP_STORAGE map on multiple attaches

This test creates a parent cgroup, and a child of that cgroup.
It attaches a cgroup_skb/egress program that simply counts packets,
to a global variable (ARRAY map), and to a CGROUP_STORAGE map.
The program is first attached to the parent cgroup only, then to
parent and child.

The test cases sends a message within the child cgroup, and because
the program is inherited across parent / child cgroups, it will
trigger the egress program for both the parent and child, if they
exist. The program, when looking up a CGROUP_STORAGE map, uses the
cgroup and attach type of the attachment parameters; therefore,
both attaches uses different cgroup storages.

We assert that all packet counts returns what we expects.

From 9e5bd1f7633bc1c3c8b25496eedfeced6d2675ff Mon Sep 17 00:00:00 2001
From: YiFei Zhu <zhuyifei@google.com>
Date: Thu, 23 Jul 2020 23:47:42 -0500
Subject: selftests/bpf: Test CGROUP_STORAGE map can't be used by multiple
 progs

The current assumption is that the lifetime of a cgroup storage
is tied to the program's attachment. The storage is created in
cgroup_bpf_attach, and released upon cgroup_bpf_detach and
cgroup_bpf_release.

Because the current semantics is that each attachment gets a
completely independent cgroup storage, and you can have multiple
programs attached to the same (cgroup, attach type) pair, the key
of the CGROUP_STORAGE map, looking up the map with this pair could
yield multiple storages, and that is not permitted. Therefore,
the kernel verifier checks that two programs cannot share the same
CGROUP_STORAGE map, even if they have different expected attach
types, considering that the actual attach type does not always
have to be equal to the expected attach type.

The test creates a CGROUP_STORAGE map and make it shared across
two different programs, one cgroup_skb/egress and one /ingress.
It asserts that the two programs cannot be both loaded, due to
verifier failure from the above reason.

Subject: selftests/bpf: Add get_stackid_cannot_attach

This test confirms that BPF program that calls bpf_get_stackid() cannot
attach to perf_event with precise_ip > 0 but not PERF_SAMPLE_CALLCHAIN;
and cannot attach if the perf_event has exclude_callchain_kernel.

Subject: bpf: Make cgroup storages shared between programs on the same cgroup

This change comes in several parts:

One, the restriction that the CGROUP_STORAGE map can only be used
by one program is removed. This results in the removal of the field
'aux' in struct bpf_cgroup_storage_map, and removal of relevant
code associated with the field, and removal of now-noop functions
bpf_free_cgroup_storage and bpf_cgroup_storage_release.

Second, we permit a key of type u64 as the key to the map.
Providing such a key type indicates that the map should ignore
attach type when comparing map keys. However, for simplicity newly
linked storage will still have the attach type at link time in
its key struct. cgroup_storage_check_btf is adapted to accept
u64 as the type of the key.

Third, because the storages are now shared, the storages cannot
be unconditionally freed on program detach. There could be two
ways to solve this issue:
* A. Reference count the usage of the storages, and free when the
     last program is detached.
* B. Free only when the storage is impossible to be referred to
     again, i.e. when either the cgroup_bpf it is attached to, or
     the map itself, is freed.
Option A has the side effect that, when the user detach and
reattach a program, whether the program gets a fresh storage
depends on whether there is another program attached using that
storage. This could trigger races if the user is multi-threaded,
and since nondeterminism in data races is evil, go with option B.

The both the map and the cgroup_bpf now tracks their associated
storages, and the storage unlink and free are removed from
cgroup_bpf_detach and added to cgroup_bpf_release and
cgroup_storage_map_free. The latter also new holds the cgroup_mutex
to prevent any races with the former.

Fourth, on attach, we reuse the old storage if the key already
exists in the map, via cgroup_storage_lookup. If the storage
does not exist yet, we create a new one, and publish it at the
last step in the attach process. This does not create a race
condition because for the whole attach the cgroup_mutex is held.
We keep track of an array of new storages that was allocated
and if the process fails only the new storages would get freed.

Subject: selftests/bpf: Test CGROUP_STORAGE behavior on shared egress +
 ingress

This mirrors the original egress-only test. The cgroup_storage is
now extended to have two packet counters, one for egress and one
for ingress. We also extend to have two egress programs to test
that egress will always share with other egress origrams in the
same cgroup. The behavior of the counters are exactly the same as
the original egress-only test.

The test is split into two, one "isolated" test that when the key
type is struct bpf_cgroup_storage_key, which contains the attach
type, programs of different attach types will see different
storages. The other, "shared" test that when the key type is u64,
programs of different attach types will see the same storage if
they are attached to the same cgroup.

Subject: Documentation/bpf: Document CGROUP_STORAGE map type

The machanics and usage are not very straightforward. Given the
changes it's better to document how it works and how to use it,
rather than having to rely on the examples and implementation to
infer what is going on.

+
+===========================
+BPF_MAP_TYPE_CGROUP_STORAGE
+===========================
+
+The ``BPF_MAP_TYPE_CGROUP_STORAGE`` map type represents a local fix-sized
+storage. It is only available with ``CONFIG_CGROUP_BPF``, and to programs that
+attach to cgroups; the programs are made available by the same Kconfig. The
+storage is identified by the cgroup the program is attached to.
+
+The map provide a local storage at the cgroup that the BPF program is attached
+to. It provides a faster and simpler access than the general purpose hash
+table, which performs a hash table lookups, and requires user to track live
+cgroups on their own.
+
+This document describes the usage and semantics of the
+``BPF_MAP_TYPE_CGROUP_STORAGE`` map type. Some of its behaviors was changed in
+Linux 5.9 and this document will describe the differences.
+
+Usage
+=====
+
+The map uses key of type of either ``__u64 cgroup_inode_id`` or
+``struct bpf_cgroup_storage_key``, declared in ``linux/bpf.h``::
+
+    struct bpf_cgroup_storage_key {
+            __u64 cgroup_inode_id;
+            __u32 attach_type;
+    };
+
+``cgroup_inode_id`` is the inode id of the cgroup directory.
+``attach_type`` is the the program's attach type.
+
+Linux 5.9 added support for type ``__u64 cgroup_inode_id`` as the key type.
+When this key type is used, then all attach types of the particular cgroup and
+map will share the same storage. Otherwise, if the type is
+``struct bpf_cgroup_storage_key``, then programs of different attach types
+be isolated and see different storages.
+
+To access the storage in a program, use ``bpf_get_local_storage``::
+
+    void *bpf_get_local_storage(void *map, u64 flags)
+
+``flags`` is reserved for future use and must be 0.
+
+There is no implicit synchronization. Storages of ``BPF_MAP_TYPE_CGROUP_STORAGE``
+can be accessed by multiple programs across different CPUs, and user should
+take care of synchronization by themselves. The bpf infrastructure provides
+``struct bpf_spin_lock`` to synchronize the storage. See
+``tools/testing/selftests/bpf/progs/test_spin_lock.c``.
+
+Examples
+========
+
+Usage with key type as ``struct bpf_cgroup_storage_key``::
+
+    #include <bpf/bpf.h>
+
+    struct {
+            __uint(type, BPF_MAP_TYPE_CGROUP_STORAGE);
+            __type(key, struct bpf_cgroup_storage_key);
+            __type(value, __u32);
+    } cgroup_storage SEC(".maps");
+
+    int program(struct __sk_buff *skb)
+    {
+            __u32 *ptr = bpf_get_local_storage(&cgroup_storage, 0);
+            __sync_fetch_and_add(ptr, 1);
+
+            return 0;
+    }
+
+Userspace accessing map declared above::
+
+    #include <linux/bpf.h>
+    #include <linux/libbpf.h>
+
+    __u32 map_lookup(struct bpf_map *map, __u64 cgrp, enum bpf_attach_type type)
+    {
+            struct bpf_cgroup_storage_key = {
+                    .cgroup_inode_id = cgrp,
+                    .attach_type = type,
+            };
+            __u32 value;
+            bpf_map_lookup_elem(bpf_map__fd(map), &key, &value);
+            // error checking omitted
+            return value;
+    }
+
+Alternatively, using just ``__u64 cgroup_inode_id`` as key type::
+
+    #include <bpf/bpf.h>
+
+    struct {
+            __uint(type, BPF_MAP_TYPE_CGROUP_STORAGE);
+            __type(key, __u64);
+            __type(value, __u32);
+    } cgroup_storage SEC(".maps");
+
+    int program(struct __sk_buff *skb)
+    {
+            __u32 *ptr = bpf_get_local_storage(&cgroup_storage, 0);
+            __sync_fetch_and_add(ptr, 1);
+
+            return 0;
+    }
+
+And userspace::
+
+    #include <linux/bpf.h>
+    #include <linux/libbpf.h>
+
+    __u32 map_lookup(struct bpf_map *map, __u64 cgrp, enum bpf_attach_type type)
+    {
+            __u32 value;
+            bpf_map_lookup_elem(bpf_map__fd(map), &cgrp, &value);
+            // error checking omitted
+            return value;
+    }
+
+Semantics
+=========
+
+``BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE`` is a variant of this map type. This
+per-CPU variant will have different memory regions for each CPU for each
+storage. The non-per-CPU will have the same memory region for each storage.
+
+Prior to Linux 5.9, the lifetime of a storage is precisely per-attachment, and
+for a single ``CGROUP_STORAGE`` map, there can be at most one program loaded
+that uses the map. A program may be attached to multiple cgroups or have
+multiple attach types, and each attach creates a fresh zeroed storage. The
+storage is freed upon detach.
+
+There is a one-to-one association between the map of each type (per-CPU and
+non-per-CPU) and the BPF program during load verification time. As a result,
+each map can only be used by one BPF program and each BPF program can only use
+one storage map of each type. Because of map can only be used by one BPF
+program, sharing of this cgroup's storage with other BPF programs were
+impossible.
+
+Since Linux 5.9, storage can be shared by multiple programs. When a program is
+attached to a cgroup, the kernel would create a new storage only if the map
+does not already contain an entry for the cgroup and attach type pair, or else
+the old storage is reused for the new attachment. If the map is attach type
+shared, then attach type is simply ignored during comparison. Storage is freed
+only when either the map or the cgroup attached to is being freed. Detaching
+will not directly free the storage, but it may cause the reference to the map
+to reach zero and indirectly freeing all storage in the map.
+
+The map is not associated with any BPF program, thus making sharing possible.
+However, the BPF program can still only associate with one map of each type
+(per-CPU and non-per-CPU). A BPF program cannot use more than one
+``BPF_MAP_TYPE_CGROUP_STORAGE`` or more than one
+``BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE``.
+
+In all versions, userspace may use the the attach parameters of cgroup and
+attach type pair in ``struct bpf_cgroup_storage_key`` as the key to the BPF map
+APIs to read or update the storage for a given attachment. For Linux 5.9
+attach type shared storages, only the first value in the struct, cgroup inode
+id, is used during comparison, so userspace may just specify a ``__u64``
+directly.
+
+The storage is bound at attach time. Even if the program is attached to parent
+and triggers in child, the storage still belongs to the parent.
+
+Userspace cannot create a new entry in the map or delete an existing entry.
+Program test runs always use a temporary storage.

Subject: bpf: Fix build on architectures with special bpf_user_pt_regs_t

Architectures like s390, powerpc, arm64, riscv have speical definition of
bpf_user_pt_regs_t. So we need to cast the pointer before passing it to
bpf_get_stack(). This is similar to bpf_get_stack_tp().

Subject: bpf, xdp: Maintain info on attached XDP BPF programs in net_device

Instead of delegating to drivers, maintain information about which BPF
programs are attached in which XDP modes (generic/skb, driver, or hardware)
locally in net_device. This effectively obsoletes XDP_QUERY_PROG command.

Such re-organization simplifies existing code already. But it also allows to
further add bpf_link-based XDP attachments without drivers having to know
about any of this at all, which seems like a good setup.
XDP_SETUP_PROG/XDP_SETUP_PROG_HW are just low-level commands to driver to
install/uninstall active BPF program. All the higher-level concerns about
prog/link interaction will be contained within generic driver-agnostic logic.

All the XDP_QUERY_PROG calls to driver in dev_xdp_uninstall() were removed.
It's not clear for me why dev_xdp_uninstall() were passing previous prog_flags
when resetting installed programs. That seems unnecessary, plus most drivers
don't populate prog_flags anyways. Having XDP_SETUP_PROG vs XDP_SETUP_PROG_HW
should be enough of an indicator of what is required of driver to correctly
reset active BPF program. dev_xdp_uninstall() is also generalized as an
iteration over all three supported mode.

Subject: bpf, xdp: Extract common XDP program attachment logic

Further refactor XDP attachment code. dev_change_xdp_fd() is split into two
parts: getting bpf_progs from FDs and attachment logic, working with
bpf_progs. This makes attachment  logic a bit more straightforward and
prepares code for bpf_xdp_link inclusion, which will share the common logic.

Subject: bpf, xdp: Add bpf_link-based XDP attachment API

Add bpf_link-based API (bpf_xdp_link) to attach BPF XDP program through
BPF_LINK_CREATE command.

bpf_xdp_link is mutually exclusive with direct BPF program attachment,
previous BPF program should be detached prior to attempting to create a new
bpf_xdp_link attachment (for a given XDP mode). Once BPF link is attached, it
can't be replaced by other BPF program attachment or link attachment. It will
be detached only when the last BPF link FD is closed.

bpf_xdp_link will be auto-detached when net_device is shutdown, similarly to
how other BPF links behave (cgroup, flow_dissector). At that point bpf_link
will become defunct, but won't be destroyed until last FD is closed.

Subject: libbpf: Add support for BPF XDP link

Sync UAPI header and add support for using bpf_link-based XDP attachment.
Make xdp/ prog type set expected attach type. Kernel didn't enforce
attach_type for XDP programs before, so there is no backwards compatiblity
issues there.

Also fix section_names selftest to recognize that xdp prog types now have
expected attach type.

From e8407fdeb9a6866784e249881f6c786a0835faba Mon Sep 17 00:00:00 2001
From: Andrii Nakryiko <andriin@fb.com>
Date: Tue, 21 Jul 2020 23:46:02 -0700
Subject: bpf, xdp: Remove XDP_QUERY_PROG and XDP_QUERY_PROG_HW XDP commands

Now that BPF program/link management is centralized in generic net_device
code, kernel code never queries program id from drivers, so
XDP_QUERY_PROG/XDP_QUERY_PROG_HW commands are unnecessary.

This patch removes all the implementations of those commands in kernel, along
the xdp_attachment_query().

This patch was compile-tested on allyesconfig.

Though we are populating and tracking ictxqec, the value is not being used
for anything so remove it altogether and save the register read.

Subject: igc: Add Receive Descriptor Minimum Threshold Count to clear HW
 counters

The statistics of this register are being tracked, however, the register
was inadvertently missed when implementing igc_clear_hw_cntrs_base().
The register is clear on read, so add it to the function so that the
register is cleared when requested so the tracked count is accurate.

list_for_each_safe is able to handle an empty list.

Subject: s390/ism: indicate correct error reason in ism_alloc_dmb()

When the ism driver allocates a new dmb in ism_alloc_dmb() it must
first check for and reserve a slot in the sba bitmap. When
find_next_zero_bit() finds no free slot then the return code is -ENOMEM.
This code conflicts with the error when the alloc() fails later in the
code. As a result of that the caller can not differentiate
between out-of-memory conditions and sba-bitmap-full conditions.
Fix that by using the return code -ENOSPC when the sba slot
reservation failed.

Subject: net/smc: unique reason code for exceeded max dmb count

When the maximum dmb buffer limit for an ism device is reached no more
dmb buffers can be registered. When this happens the reason code is set
to SMC_CLC_DECL_MEM indicating out-of-memory. This is the same reason
code that is used when no memory could be allocated for the new dmb
buffer.
This is confusing for users when they see this error but there is more
memory available. To solve this set a separate new reason code when the
maximum dmb limit exceeded.

Cited commit mistakenly copied provided option to 'val' instead of to
'mfc':

```
-               if (copy_from_user(&mfc, optval, sizeof(mfc))) {

```

Fix this by copying the option to 'mfc'.

Subject: net: Removed the device type check to add mpls support for devices

MPLS has no dependency with the device type of underlying devices.
Hence the device type check to add mpls support for devices can be
avoided.

Subject: bnxt_en: Remove PCIe non-counters from ethtool statistics

Remove PCIe non-counters display from ethtool statistics, as
they are not simple counters but register dump.  The next few
patches will add logic to detect counter roll-over and it won't
work with these PCIe non-counters.

There will be a follow up patch to get PCIe information via
ethtool register dump.

Subject: bnxt_en: Update firmware interface to 1.10.1.54.

Main changes are 200G support and fixing the definitions of discard and
error counters to match the hardware definitions.

Because the HWRM_PORT_PHY_QCFG message size has now exceeded the max.
encapsulated response message size of 96 bytes from the PF to the VF,
we now need to cap this message to 96 bytes for forwarding.  The forwarded
response only needs to contain the basic link status and speed information
and can be capped without adding the new information.

v2: Fix bnxt_re compile error.

Subject: bnxt_en: Refactor statistics code and structures.

The driver manages multiple statistics structures of different sizes.
They are all allocated, freed, and handled practically the same.  Define
a new bnxt_stats_mem structure and common allocation and free functions
for all staistics memory blocks.

Subject: bnxt_en: Allocate additional memory for all statistics blocks.

Some of these DMAed hardware counters are not full 64-bit counters and
so we need to accumulate them as they overflow.  Allocate copies of these
DMA statistics memory blocks with the same size for accumulation.  The
hardware counter widths are also counter specific so we allocate
memory for masks that correspond to each counter.

Subject: bnxt_en: Retrieve hardware counter masks from firmware if available.

Newer firmware has a new call HWRM_FUNC_QSTATS_EXT to retrieve the
masks of all ring counters.  Make this call when supported to
initialize the hardware masks of all ring counters.  If the call
is not available, assume 48-bit ring counter masks on P5 chips.

Subject: bnxt_en: Accumulate all counters.

Now that we have the infrastructure in place, add the new function
bnxt_accumulate_all_stats() to periodically accumulate and check for
counter rollover of all ring stats and port stats.

A chip bug was also discovered that could cause some ring counters to
become 0 during DMA.  Workaround by ignoring zeros on the affected
chips.

Some older frimware will reset port counters during ifdown.  We need
to check for that and free the accumulated port counters during ifdown
to prevent bogus counter overflow detection during ifup.

Subject: bnxt_en: Switch over to use the 64-bit software accumulated counters.

Now we can report all the full 64-bit CPU endian software accumulated
counters instead of the hw counters, some of which may be less than
64-bit wide.  Define the necessary macros to access the software
counters.

Subject: qed: fix the allocation of the chains with an external PBL

Dan reports static checker warning:

"The patch 9b6ee3cf95d3: "qed: sanitize PBL chains allocation" from Jul
23, 2020, leads to the following static checker warning:

	drivers/net/ethernet/qlogic/qed/qed_chain.c:299 qed_chain_alloc_pbl()
	error: uninitialized symbol 'pbl_virt'.

drivers/net/ethernet/qlogic/qed/qed_chain.c

   252          struct addr_tbl_entry *addr_tbl;
   253          dma_addr_t phys, pbl_phys;
   254          __le64 *pbl_virt;

                        ^^^^^^^^^^^
[...]
"

This issue was introduced with commit c3a321b06a80 ("qed: simplify
initialization of the chains with an external PBL"), when
chain->pbl_sp.table_virt initialization was moved up to
qed_chain_init_params().
Fix it by initializing pbl_virt with an already filled chain struct field.

Fixes: c3a321b06a80 ("qed: simplify initialization of the chains with an external PBL")

Subject: hsr: enhance netlink socket interface to support PRP

Parallel Redundancy Protocol (PRP) is another redundancy protocol
introduced by IEC 63439 standard. It is similar to HSR in many
aspects:-

 - Use a pair of Ethernet interfaces to created the PRP device
 - Use a 6 byte redundancy protocol part (RCT, Redundancy Check
   Trailer) similar to HSR Tag.
 - Has Link Redundancy Entity (LRE) that works with RCT to implement
   redundancy.

Key difference is that the protocol unit is a trailer instead of a
prefix as in HSR. That makes it inter-operable with tradition network
components such as bridges/switches which treat it as pad bytes,
whereas HSR nodes requires some kind of translators (Called redbox) to
talk to regular network devices. This features allows regular linux box
to be converted to a DAN-P box. DAN-P stands for Dual Attached Node - PRP
similar to DAN-H (Dual Attached Node - HSR).

Add a comment at the header/source code to explicitly state that the
driver files also handles PRP protocol as well.

protocol ops ptr in the private hsr structure to hold function
pointers as some of the functions at protocol level packet
handling is different for HSR vs PRP. It is expected that PRP will
add its of set of functions for protocol handling. Modify existing
hsr_announce() function to call proto_ops->send_sv_frame() to send
supervision frame for HSR. This is expected to be different for PRP.
So introduce a ops function ptr, send_sv_frame() for the same and
initialize it to send_hsr_supervsion_frame(). Modify hsr_announce()
to call proto_ops->send_sv_frame().

Subject: net: prp: add supervision frame generation utility function

Add support for generation of PRP supervision frames. For PRP,
supervision frame format is similar to HSR version 0, but have
a PRP Redundancy Control Trailer (RCT) added and uses a different
message type, PRP_TLV_LIFE_CHECK_DD. Also update
is_supervision_frame() to include the new message type used for
PRP supervision frame.

Subject: net: prp: add packet handling support

DAN-P (Dual Attached Nodes PRP) nodes are expected to receive
traditional IP packets as well as PRP (Parallel Redundancy
Protocol) tagged (trailer) packets. PRP trailer is 6 bytes
of PRP protocol unit called RCT, Redundancy Control Trailer
(RCT) similar to HSR tag. PRP network can have traditional
devices such as bridges/switches or PC attached to it and
should be able to communicate. Regular Ethernet devices treat
the RCT as pads.  This patch adds logic to format L2 frames
from network stack to add a trailer (RCT) and send it as
duplicates over the slave interfaces when the protocol is
PRP as per IEC 62439-3. At the ingress, it strips the trailer,
do duplicate detection and rejection and forward a stripped
frame up the network stack. PRP device should accept frames
from Singly Attached Nodes (SAN) and thus the driver mark
the link where the frame came from in the node table.

Print PRP specific information from node table as part of debugfs
node table display. Also display the node as DAN-H or DAN-P depending
on the info from node table.

Subject: sfc: remove efx_ethtool_nway_reset()

An MDIO-based n-way restart does not make sense for any of the NICs
 supported by this driver, nor for the coming EF100.
Unlike on Falcon (which was already split off into a separate driver),
 the PHY on all of Siena, EF10 and EF100 is managed by MC firmware.
While Siena can talk to the PHY over MDIO, doing so for anything other
 than debugging purposes (mdio_mii_ioctl) is likely to confuse the
 firmware.
(According to the SFC firmware team, this support was originally added
 to the Siena driver early in the development of that product, before
 it was decided to have firmware manage the PHY.)

Subject: sfc_ef100: register accesses on EF100

EF100 adds a few new valid addresses for efx_writed_page(), as well as
 a Function Control Window in the BAR whose location is variable.

From 51b35a454efdcd86f578e61ec8bf7596299c5f80 Mon Sep 17 00:00:00 2001
From: Edward Cree <ecree@solarflare.com>

Subject: sfc: skeleton EF100 PF driver

No TX or RX path, no MCDI, not even an ifup/down handler.
Besides stubs, the bulk of the patch deals with reading the Xilinx
 extended PCIe capability, which tells us where to find our BAR.

Though in the same module, EF100 has its own struct pci_driver,
 which is named sfc_ef100.

A small number of additional nic_type methods are added; those in the
 TX (tx_enqueue) and RX (rx_packet) paths are called through indirect
 call wrappers to minimise the performance impact.

We can't actually do the MCDI to probe it fully until we have working
 MCDI, which comes later, but we need efx->phy_data to be allocated so
 that when we get MCDI events the link-state change handler doesn't
 NULL-dereference.

Subject: sfc_ef100: implement ndo_open/close and EVQ probing

Channels are probed, but actual event handling is still stubbed out.

Stub implementation of check_caps is needed because ptp.c will call into
 it from efx_ptp_use_mac_tx_timestamps() to decide if it wants TXQs.

Subject: sfc_ef100: actually perform resets

In ef100_reset(), make the MCDI call to do the reset.
Also, do a reset at start-of-day during probe, to put the function in
 a clean state.

Subject: tools, bpftool: Skip type probe if name is not found

For probing program and map types, bpftool loops on type values and uses
the relevant type name in prog_type_name[] or map_type_name[]. To ensure
the name exists, we exit from the loop if we go over the size of the
array.

However, this is not enough in the case where the arrays have "holes" in
them, program or map types for which they have no name, but not at the
end of the list. This is currently the case for BPF_PROG_TYPE_LSM, not
known to bpftool and which name is a null string. When probing for
features, bpftool attempts to strlen() that name and segfaults.

Let's fix it by skipping probes for "unknown" program and map types,
with an informational message giving the numeral value in that case.

Subject: Bluetooth: btusb: Fix and detect most of the Chinese Bluetooth
 controllers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For some reason they tend to squat on the very first CSR/
Cambridge Silicon Radio VID/PID instead of paying fees.

This is an extremely common problem; the issue goes as back as 2013
and these devices are only getting more popular, even rebranded by
reputable vendors and sold by retailers everywhere.

So, at this point in time there are hundreds of modern dongles reusing
the ID of what originally was an early Bluetooth 1.1 controller.

Linux is the only place where they don't work due to spotty checks
in our detection code. It only covered a minimum subset.

So what's the big idea? Take advantage of the fact that all CSR
chips report the same internal version as both the LMP sub-version and
HCI revision number. It always matches, couple that with the manufacturer
code, that rarely lies, and we now have a good idea of who is who.

Additionally, by compiling a list of user-reported HCI/lsusb dumps, and
searching around for legit CSR dongles in similar product ranges we can
find what CSR BlueCore firmware supported which Bluetooth versions.

That way we can narrow down ranges of fakes for each of them.

e.g. Real CSR dongles with LMP subversion 0x73 are old enough that
     support BT 1.1 only; so it's a dead giveaway when some
     third-party BT 4.0 dongle reuses it.

So, to sum things up; there are multiple classes of fake controllers
reusing the same 0A12:0001 VID/PID. This has been broken for a while.

Known 'fake' bcdDevices: 0x0100, 0x0134, 0x1915, 0x2520, 0x7558, 0x8891
  IC markings on 0x7558: FR3191AHAL 749H15143 (???)

Subject: net/mlx5: Hold pages RB tree per VF

Per page request event, FW request to allocated or release pages for a
single function. Driver maintains FW pages object per function, so there
is no need to hold one global page data-base. Instead, have a page
data-base per function, which will improve performance release flow in all
cases, especially for "release all pages".

As the range of function IDs is large and not sequential, use xarray to
store a per function ID page data-base, where the function ID is the key.

Upon first allocation of a page to a function ID, create the page
data-base per function. This data-base will be released only at pagealloc
mechanism cleanup.

NIC: ConnectX-4 Lx
CPU: Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz
Test case: 32 VFs, measure release pages on one VF as part of FLR
Before: 0.021 Sec
After:  0.014 Sec

The improvement depends on amount of VFs and memory utilization
by them. Time measurements above were taken from idle system.

When eswitch is enabled, VFs might not be enabled. Hence, consider
maximum number of VFs.
This further closes the gap between handling VF vports between ECPF and
PF.

Subject: net/mlx5: E-switch, Use eswitch total_vports

Currently steering table and rx group initialization helper
routines works on the total_vports passed as input parameter.

Both eswitch helpers work on the mlx5_eswitch and thereby have access
to esw->total_vports. Hence use it directly instead of passing it
via function input arguments.

Subject: net/mlx5e: Link non uplink representors to PCI device

Currently PF and VF representors are exposed as virtual device.
They are not linked to its parent PCI device like how uplink
representor is linked.
Due to this, PF and VF representors cannot benefit of the
systemd defined naming scheme. This requires special handling
by the users.

Hence, link the PF and VF representors to their parent PCI device
similar to existing uplink representor netdevice.

Example:
udevadm output before linking to PCI device:
$ udevadm test-builtin net_id  /sys/class/net/eth6
Load module index
Network interface NamePolicy= disabled on kernel command line, ignoring.
Parsed configuration file /usr/lib/systemd/network/99-default.link
Created link configuration context.
Using default interface naming scheme 'v243'.
ID_NET_NAMING_SCHEME=v243
Unload module index
Unloaded link configuration context.

udevadm output after linking to PCI device:
$ udevadm test-builtin net_id /sys/class/net/eth6
Load module index
Network interface NamePolicy= disabled on kernel command line, ignoring.
Parsed configuration file /usr/lib/systemd/network/99-default.link
Created link configuration context.
Using default interface naming scheme 'v243'.
ID_NET_NAMING_SCHEME=v243
ID_NET_NAME_PATH=enp0s8f0npf0vf0
Unload module index
Unloaded link configuration context.

In past there was little concern over seeing 10,000 lines output
showing up at thread [1] is not applicable as ndo ops for VF
handling is not exposed for all the 100 repesentors for mlx5 devices.

Additionally alternative device naming [2] to overcome shorter device
naming is also part of the latest systemd release v245.

Subject: net/mlx5e: RX, Re-work initializaiton of RX function pointers

Instead of exposing the RQ datapath handlers (from en_rx.c) so that
they are set in the control path (in en_main.c), wrap this logic
in a single function in en_rx.c and expose it alone.

Every profile will now have a pointer to the new mlx5e_rx_handlers
structure, instead of directly pointing to the previously-exposed
RQ handlers.

This significantly improves locality and modularity of the driver,
and allows many functions in en_rx.c to become static.

Subject: net/mlx5e: Add support for PCI relaxed ordering

The concept of Relaxed Ordering in the PCI Express environment allows
switches in the path between the Requester and Completer to reorder some
transactions just received before others that were previously enqueued.

In ETH driver, there is no question of write integrity since each memory
segment is written only once per cycle. In addition, the driver doesn't
access the memory shared with the hardware until the corresponding CQE
arrives indicating all PCI transactions are done.

Running TCP single stream over ConnectX-4 LX, ARM CPU on remote-numa has
300% improvement in the bandwidth.

With relaxed ordering turned off: BW:10 [GB/s]
With relaxed ordering turned on: BW:40 [GB/s]

The driver turns relaxed ordering with respect to the firmware
capabilities and the return value from pcie_relaxed_ordering_enabled().

Subject: net/mlx5: DR, Reduce print level for matcher print

There is no need to print on each unsuccessful matcher
ip_version combination since it probably will happen when
trying to create all the possible combinations.
On a real failure we have a print in the calling function.

Subject: net/mlx5: Use fallthrough pseudo-keyword

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Subject: net/mlx5: drop unnecessary list_empty

list_for_each_entry is able to handle an empty list.
The only effect of avoiding the loop is not initializing the
index variable.
Drop list_empty tests in cases where these variables are not
used.

Note that list_for_each_entry is defined in terms of list_first_entry,
which indicates that it should not be used on an empty list.  But in
list_for_each_entry, the element obtained by list_first_entry is not
really accessed, only the address of its list_head field is compared
to the address of the list head, so the list_first_entry is safe.

The semantic patch that makes this change is as follows (with another
variant for the no brace case): (http://coccinelle.lip6.fr/)

<smpl>
@@
expression x,e;
iterator name list_for_each_entry;
statement S;
identifier i;

-if (!(list_empty(x))) {
   list_for_each_entry(i,x,...) S

Subject: xdp: Prevent kernel-infoleak in xsk_getsockopt()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

xsk_getsockopt() is copying uninitialized stack memory to userspace when
'extra_stats' is 'false'. Fix it. Doing '= {};' is sufficient since currently
'struct xdp_statistics' is defined as follows:

  struct xdp_statistics {
    __u64 rx_dropped;
    __u64 rx_invalid_descs;
    __u64 tx_invalid_descs;
    __u64 rx_ring_full;
    __u64 rx_fill_ring_empty_descs;
    __u64 tx_ring_empty_descs;
  };

When being copied to the userspace, 'stats' will not contain any uninitialized
'holes' between struct fields.

Subject: Bluetooth: Fix suspend notifier race

Unregister from suspend notifications and cancel suspend preparations
before running hci_dev_do_close. Otherwise, the suspend notifier may
race with unregister and cause cmd_timeout even after hdev has been
freed.

Below is the trace from when this panic was seen:

Subject: farsync: use generic power management

The .suspend() and .resume() callbacks are not defined for this driver.
Still, their power management structure follows the legacy framework. To
bring it under the generic framework, simply remove the binding of
callbacks from "struct pci_driver".

Change code indentation from space to tab in "struct pci_driver".

Subject: mlxsw: core: Add ethtool support for QSFP-DD transceivers

The Quad Small Form Factor Pluggable Double Density (QSFP-DD) hardware
specification defines a form factor that supports up to 400 Gbps in
aggregate over an 8x50-Gbps electrical interface. The QSFP-DD supports
both optical and copper interfaces.

Implementation is based on Common Management Interface Specification;
Rev 4.0 May 8, 2019. Table 8-2 "Identifier and Status Summary (Lower
Page)" from this spec defines "Id and Status" fields located at offsets
00h - 02h. Bit 2 at offset 02h ("Flat_mem") specifies QSFP EEPROM memory
mode, which could be "upper memory flat" or "paged". Flat memory mode is
coded "1", and indicates that only page 00h is implemented in EEPROM.
Paged memory is coded "0" and indicates that pages 00h, 01h, 02h, 10h
and 11h are implemented. Pages 10h and 11h are currently not supported
by the driver.

"Flat" memory mode is used for the passive copper transceivers. For this
type only page 00h (256 bytes) is available. "Paged" memory is used for
the optical transceivers. For this type pages 00h (256 bytes), 01h (128
bytes) and 02h (128 bytes) are available. Upper page 01h contains static
advertising field, while upper page 02h contains the module-defined
thresholds and lane-specific monitors.

Extend enumerator 'mlxsw_reg_mcia_eeprom_module_info_id' with additional
field 'MLXSW_REG_MCIA_EEPROM_MODULE_INFO_TYPE_ID'. This field is used to
indicate for QSFP-DD transceiver type which memory mode is to be used.

Expose 256 bytes buffer for QSFP-DD passive copper transceiver and
512 bytes buffer for optical.

Subject: net: make sockptr_is_null strict aliasing safe

While the kernel in general is not strict aliasing safe we can trivially
do that in sockptr_is_null without affecting code generation, so always
check the actually assigned union member.

Subject: net: improve the user pointer check in init_user_sockptr

Make sure not just the pointer itself but the whole range lies in
the user address space.  For that pass the length and then use
the access_ok helper to do the check.

Subject: bpf, selftests: use :: 1 for localhost in tcp_server.py

Using localhost requires the host to have a /etc/hosts file with that
specific line in it. By default my dev box did not, they used
ip6-localhost, so the test was failing. To fix remove the need for any
/etc/hosts and use ::1.

I could just add the line, but this seems easier.

Subject: bpf: Fix build without CONFIG_NET when using BPF XDP link

Entire net/core subsystem is not built without CONFIG_NET. linux/netdevice.h
just assumes that it's always there, so the easiest way to fix this is to
conditionally compile out bpf_xdp_link_attach() use in bpf/syscall.c.

Fixes: aa8d3a716b59 ("bpf, xdp: Add bpf_link-based XDP attachment API")

Subject: mptcp: Allow DATA_FIN in headers without TCP FIN

RFC 8684-compliant DATA_FIN needs to be sent and ack'd before subflows
are closed with TCP FIN, so write DATA_FIN DSS headers whenever their
transmission has been enabled by the MPTCP connection-level socket.

Subject: mptcp: Track received DATA_FIN sequence number and add related
 helpers

Incoming DATA_FIN headers need to propagate the presence of the DATA_FIN
bit and the associated sequence number to the MPTCP layer, even when
arriving on a bare ACK that does not get added to the receive queue. Add
structure members to store the DATA_FIN information and helpers to set
and check those values.

Subject: mptcp: Use full MPTCP-level disconnect state machine

RFC 8684 appendix D describes the connection state machine for
MPTCP. This patch implements the DATA_FIN / DATA_ACK exchanges and
MPTCP-level socket state changes described in that appendix, rather than
simply sending DATA_FIN along with TCP FIN when disconnecting subflows.

DATA_FIN is now sent and acknowledged before shutting down the
subflows. Received DATA_FIN information (if not part of a data packet)
is written to the MPTCP socket when the incoming DSS option is parsed by
the subflow, and the MPTCP worker is scheduled to process the
flag. DATA_FIN received as part of a full DSS mapping will be handled
when the mapping is processed.

The DATA_FIN is acknowledged by the worker if the reader is caught
up. If there is still data to be moved to the MPTCP-level queue, ack_seq
will be incremented to account for the DATA_FIN when it reaches the end
of the stream and a DATA_ACK will be sent to the peer.

Subject: mptcp: Safely store sequence number when sending data

The MPTCP socket's write_seq member can be read without the msk lock
held, so use WRITE_ONCE() to store it.

Subject: Add pldmfw library for PLDM firmware update

The pldmfw library is used to implement common logic needed to flash
devices based on firmware files using the format described by the PLDM
for Firmware Update standard.

This library consists of logic to parse the PLDM file format from
a firmware file object, as well as common logic for sending the relevant
PLDM header data to the device firmware.

A simple ops table is provided so that device drivers can implement
device specific hardware interactions while keeping the common logic to
the pldmfw library.

This library will be used by the Intel ice networking driver as part of
implementing device flash update via devlink. The library aims to be
vendor and device agnostic. For this reason, it has been placed in
lib/pldmfw, in the hopes that other devices which use the PLDM firmware
file format may benefit from it in the future. However, do note that not
all features defined in the PLDM standard have been implemented.

+=========================
+Driver-specific callbacks
+=========================
+
+The ``pldmfw`` module relies on the device driver for implementing device
+specific behavior using the following operations.
+
+``.match_record``
+-----------------
+
+The ``.match_record`` operation is used to determine whether a given PLDM
+record matches the device being updated. This requires comparing the record
+descriptors in the record with information from the device. Many record
+descriptors are defined by the PLDM standard, but it is also allowed for
+devices to implement their own descriptors.
+
+The ``.match_record`` operation should return true if a given record matches
+the device.
+
+``.send_package_data``
+----------------------
+
+The ``.send_package_data`` operation is used to send the device-specific
+package data in a record to the device firmware. If the matching record
+provides package data, ``pldmfw`` will call the ``.send_package_data``
+function with a pointer to the package data and with the package data
+length. The device driver should send this data to firmware.
+
+``.send_component_table``
+-------------------------
+
+The ``.send_component_table`` operation is used to forward component
+information to the device. It is called once for each applicable component,
+that is, for each component indicated by the matching record. The
+device driver should send the component information to the device firmware,
+and wait for a response. The provided transfer flag indicates whether this
+is the first, last, or a middle component, and is expected to be forwarded
+to firmware as part of the component table information. The driver should an
+error in the case when the firmware indicates that the component cannot be
+updated, or return zero if the component can be updated.
+
+``.flash_component``
+--------------------
+
+The ``.flash_component`` operation is used to inform the device driver to
+flash a given component. The driver must perform any steps necessary to send
+the component data to the device.
+
+``.finalize_update``
+--------------------
+
+The ``.finalize_update`` operation is used by the ``pldmfw`` library in
+order to allow the device driver to perform any remaining device specific
+logic needed to finish the update.

+PLDM Firmware file format overview
+==================================
+
+A PLDM firmware package is a binary file which contains a header that
+describes the contents of the firmware package. This includes an initial
+package header, one or more firmware records, and one or more components
+describing the actual flash contents to program.
+
+This diagram provides an overview of the file format::
+
+        overall file layout

+      +----------------------+
+
+Package Header
+==============
+
+The package header begins with the UUID of the PLDM file format, and
+contains information about the version of the format that the file uses. It
+also includes the total header size, a release date, the size of the
+component bitmap, and an overall package version.
+
+The following diagram provides an overview of the package header::
+
+             header layout
+      +-------------------------+

+      | Component Bitmap Length |
+      +-------------------------+
+      | Package Version Info    |
+      +-------------------------+
+
+Device Records
+==============
+
+The device firmware records area starts with a count indicating the total
+number of records in the file, followed by each record. A single device
+record describes what device matches this record. All valid PLDM firmware
+files must contain at least one record, but optionally may contain more than
+one record if they support multiple devices.
+
+Each record will identify the device it supports via TLVs that describe the
+device, such as the PCI device and vendor information. It will also indicate
+which set of components that are used by this device. It is possible that
+only subset of provided components will be used by a given record. A record
+may also optionally contain device-specific package data that will be used
+by the device firmware during the update process.
+
+The following diagram provides an overview of the device record area::

+Component Info
+==============
+
+The component information area begins with a count of the number of
+components. Following this count is a description for each component. The
+component information points to the location in the file where the component
+data is stored, and includes version data used to identify the version of
+the component.

+PLDM Firmware Flash Update Library
+==================================

+the PLDM for Firmware Update standard
+<https://www.dmtf.org/documents/pmci/pldm-firmware-update-specification-100>.

+==================================
+Overview of the ``pldmfw`` library
+==================================
+
+The ``pldmfw`` library is intended to be used by device drivers for
+implementing device flash update based on firmware files following the PLDM
+firwmare file format.
+
+It is implemented using an ops table that allows device drivers to provide
+the underlying device specific functionality.
+
+``pldmfw`` implements logic to parse the packed binary format of the PLDM
+firmware file into data structures, and then uses the provided function
+operations to determine if the firmware file is a match for the device. If
+so, it sends the record and component data to the firmware using the device
+specific implementations provided by device drivers. Once the device
+firmware indicates that the update may be performed, the firmware data is
+sent to the device for programming.
+
+Parsing the PLDM file
+=====================
+
+The PLDM file format uses packed binary data, with most multi-byte fields
+stored in the Little Endian format. Several pieces of data are variable
+length, including version strings and the number of records and components.
+Due to this, it is not straight forward to index the record, record
+descriptors, or components.
+
+To avoid proliferating access to the packed binary data, the ``pldmfw``
+library parses and extracts this data into simpler structures for ease of
+access.
+
+In order to safely process the firmware file, care is taken to avoid
+unaligned access of multi-byte fields, and to properly convert from Little
+Endian to CPU host format. Additionally the records, descriptors, and
+components are stored in linked lists.
+
+Performing a flash update
+=========================
+
+To perform a flash update, the ``pldmfw`` module performs the following
+steps
+
+1. Parse the firmware file for record and component information
+2. Scan through the records and determine if the device matches any record
+   in the file. The first matched record will be used.
+3. If the matching record provides package data, send this package data to
+   the device.
+4. For each component that the record indicates, send the component data to
+   the device. For each component, the firmware may respond with an
+   indication of whether the update is suitable or not. If any component is
+   not suitable, the update is canceled.
+5. For each component, send the binary data to the device firmware for
+   updating.
+6. After all components are programmed, perform any final device-specific
+   actions to finalize the update.

Subject: ice: add flags indicating pending update of firmware module

After a flash update, the pending status of the update can be determined
from the device capabilities.

Read the appropriate device capability and store whether there is
a pending update awaiting a reboot.

From d69ea414c9b498064d4cd3ebbe2fd4b8298568bc Mon Sep 17 00:00:00 2001
From: Jacob Keller <jacob.e.keller@intel.com>

Subject: ice: implement device flash update via devlink

Use the newly added pldmfw library to implement device flash update for
the Intel ice networking device driver. This support uses the devlink
flash update interface.

The main parts of the flash include the Option ROM, the netlist module,
and the main NVM data. The PLDM firmware file contains modules for each
of these components.

Using the pldmfw library, the provided firmware file will be scanned for
the three major components, "fw.undi" for the Option ROM, "fw.mgmt" for
the main NVM module containing the primary device firmware, and
"fw.netlist" containing the netlist module.

The flash is separated into two banks, the active bank containing the
running firmware, and the inactive bank which we use for update. Each
module is updated in a staged process. First, the inactive bank is
erased, preparing the device for update. Second, the contents of the
component are copied to the inactive portion of the flash. After all
components are updated, the driver signals the device to switch the
active bank during the next EMP reset (which would usually occur during
the next reboot).

Although the firmware AdminQ interface does report an immediate status
for each command, the NVM erase and NVM write commands receive status
asynchronously. The driver must not continue writing until previous
erase and write commands have finished. The real status of the NVM
commands is returned over the receive AdminQ. Implement a simple
interface that uses a wait queue so that the main update thread can
sleep until the completion status is reported by firmware. For erasing
the inactive banks, this can take quite a while in practice.

To help visualize the process to the devlink application and other
applications based on the devlink netlink interface, status is reported
via the devlink_flash_update_status_notify. While we do report status
after each 4k block when writing, there is no real status we can report
during erasing. We simply must wait for the complete module erasure to
finish.

With this implementation, basic flash update for the ice hardware is
supported.

Subject: net_sched: initialize timer earlier in red_init()

When red_init() fails, red_destroy() is called to clean up.
If the timer is not initialized yet, del_timer_sync() will
complain. So we have to move timer_setup() before any failure.

Subject: net: dsa: rtl8366: Fix VLAN semantics

The RTL8366 would not handle adding new members (ports) to
a VLAN: the code assumed that ->port_vlan_add() was only
called once for a single port. When intializing the
switch with .configure_vlan_while_not_filtering set to
true, the function is called numerous times for adding
all ports to VLAN1, which was something the code could
not handle.

Alter rtl8366_set_vlan() to just |= new members and
untagged flags to 4k and MC VLAN table entries alike.
This makes it possible to just add new ports to a
VLAN.

Put in some helpful debug code that can be used to find
any further bugs here.

Subject: net: dsa: rtl8366: Fix VLAN set-up

Alter the rtl8366_vlan_add() to call rtl8366_set_vlan()
inside the loop that goes over all VIDs since we now
properly support calling that function more than once.
Augment the loop to postincrement as this is more
intuitive.

The loop moved past the last VID but called
rtl8366_set_vlan() with the port number instead of
the VID, assuming a 1-to-1 correspondence between
ports and VIDs. This was also a bug.

Subject: net: stmmac: only call pmt() during suspend/resume if HW enables PMT

This is to prepare WOL support with phy. Compared with WOL
implementation which relies on the MAC's PMT features, in phy
supported WOL case, device_may_wakeup() may also be true, but we
should not call mac's pmt() function if HW doesn't enable PMT.

And during resume, we should call phylink_start() if PMT is disabled.

Subject: net: stmmac: Support WOL with phy

Currently, the stmmac driver WOL implementation relies on MAC's PMT
feature. We have a case: the MAC HW doesn't enable PMT, instead, we
rely on the phy to support WOL. Implement the support for this case.

Subject: ice: Implement LFC workaround

There is a bug where the LFC settings are not being preserved
through a link event.  The registers in question are the ones
that are touched (and restored) when a set_local_mib AQ command
is performed.

On a link-up event, make sure that a set_local_mib is being
performed.

Move the function ice_aq_set_lldp_mib() from the DCB specific
ice_dcb.c to ice_common.c so that the driver always has access
to this AQ command.

Subject: ice: Fix link broken after GLOBR reset

After a GLOBR, the link was broken so that a link
up situation was being seen as a link down.

The problem was that the rebuild process was updating
the port_info link status without doing any of the
other things that need to be done when link changes.

This was causing the port_info struct to have current
"UP" information so that any further UP interrupts
were skipped as redundant.

The rebuild flow should *not* be updating the port_info
struct link information, so eliminate this and leave
it to the link event handling code.

Subject: ice: fix link event handling timing

When the driver experiences a link event (especially link up)
there can be multiple events generated. Some of these are
link fault and still have a state of DOWN set.  The problem
happens when the link comes UP during the PF driver handling
one of the LINK DOWN events.  The status of the link is updated
and is now seen as UP, so when the actual LINK UP event comes,
the port information has already been updated to be seen as UP,
even though none of the UP activities have been completed.

After the link information has been updated in the link
handler and evaluated for MEDIA PRESENT, if the state
of the link has been changed to UP, treat the DOWN event

Subject: ice: restore VF MSI-X state during PCI reset

During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability
register will be cleared. This can lead to issues when a VF is
assigned to a VM because in these cases the VF driver receives no
indication of the PF PCI error/reset and additionally it is incapable
of restoring the cleared flag in the hypervisor configuration space
without fully reinitializing the driver interrupt functionality.

Since the VF driver is unable to easily resolve this condition on its own,
restore the VF MSI-X flag during the PF PCI reset handling.

Return ICE_ERR_DOES_NOT_EXIST return code if admin command error code is
ICE_AQ_RC_ENOENT (not exist). ice_aq_sw_rules is used when switch
rule is getting added/deleted/updated. In case of delete/update
switch rule, admin command can return ICE_AQ_RC_ENOENT error code
if such rule does not exist, hence return ICE_ERR_DOES_NOT_EXIST error
code from ice_aq_sw_rule, so that caller of this function can decide
how to handle ICE_ERR_DOES_NOT_EXIST.

Subject: ice: fix overwriting TX/RX descriptor values when rebuilding VSI

If a user sets the value of the TX or RX descriptors to some non-default
value using 'ethtool -G' then we need to not overwrite the values when
we rebuild the VSI. The VSI rebuild could happen as a result of a user
setting the number of queues via the 'ethtool -L' command. Fix this by
checking to see if the value we have stored is non-zero and if it is
then don't change the value.

By default the queues are configured in legacy mode. The default

incorrect. This caused the unbalanced BW sharing among siblings.
The recommended default value is applied.

Subject: ice: distribute Tx queues evenly

Distribute the Tx queues evenly across all queue groups. This will
help the queues to get more equal sharing among the queues when all
are in use.

In the previous algorithm, the next queue group node will be picked up
only after the previous one filled with max children.
For example: if VSI is configured with 9 queues, the first 8 queues
will be assigned to queue group 1 and the 9th queue will be assigned to
queue group 2.

The 2 queue groups split the bandwidth between them equally (50:50).
The first queue group node will share the 50% bandwidth with all of
its children (8 queues). And the second queue group node will share
the entire 50% bandwidth with its only children.

The new algorithm will fix this issue.

This is a port of i40e commit 705639572e8c ("i40e: need_wakeup flag might
not be set for Tx").

Quoting the original commit message:

"The need_wakeup flag for Tx might not be set for AF_XDP sockets that
are only used to send packets. This happens if there is at least one
outstanding packet that has not been completed by the hardware and we
get that corresponding completion (which will not generate an interrupt
since interrupts are disabled in the napi poll loop) between the time we
stopped processing the Tx completions and interrupts are enabled again.
In this case, the need_wakeup flag will have been cleared at the end of
the Tx completion processing as we believe we will get an interrupt from
the outstanding completion at a later point in time. But if this
completion interrupt occurs before interrupts are enable, we lose it and
should at that point really have set the need_wakeup flag since there
are no more outstanding completions that can generate an interrupt to
continue the processing. When this happens, user space will see a Tx
queue need_wakeup of 0 and skip issuing a syscall, which means will
never get into the Tx processing again and we have a deadlock."

As a result, packet processing stops. This patch introduces a fix for
this issue, by always setting the need_wakeup flag at the end of an
interrupt processing. This ensures that the deadlock will not happen.

Subject: ice: Allow all VLANs in safe mode

Currently the PF VSI's context parameters are left in a bad state when
going into safe mode. This is causing VLAN traffic to not pass. Fix this
by configuring the PF VSI to allow all VLAN tagged traffic.

Also, remove redundant comment explaining the safe mode flow in
ice_probe().

Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Subject: Bluetooth: Configure controller address resolution if available

When the LL Privacy support is available, then as part of enabling or
disabling passive background scanning, it is required to set up the
controller based address resolution as well.

Since only passive background scanning is utilizing the whitelist, the
address resolution is now bound to the whitelist and passive background
scanning. All other resolution can be easily done by the host stack.

Subject: Revert "Bluetooth: btusb: Disable runtime suspend on Realtek devices"

This reverts commit 7ecacafc240638148567742cca41aa7144b4fe1e.

Testing this change on a board with RTL8822CE, I found that enabling
autosuspend has no effect on the stability of the system. The board
continued working after autosuspend, suspend and reboot.

The original commit makes it impossible to enable autosuspend on working
systems so it should be reverted. Disabling autosuspend should be done
via module param or udev in userspace instead.

Subject: iavf: use generic power management

With the support of generic PM callbacks, drivers no longer need to use
legacy .suspend() and .resume() in which they had to maintain PCI states
changes and device's power state themselves. The required operations are
done by PCI core.

PCI drivers are not expected to invoke PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(),
pci_set_power_state(), etc. Their tasks are completed by PCI core itself.

Compile-tested only.

Subject: igbvf: use generic power management

Remove legacy PM callbacks and use generic operations. With legacy code,
drivers were responsible for handling PCI PM operations like
pci_save_state(). In generic code, all these are handled by PCI core.

The generic suspend() and resume() are called at the same point the legacy
ones were called. Thus, it does not affect the normal functioning of the
driver.

__maybe_unused attribute is used with .resume() but not with .suspend(), as
.suspend() is called by .shutdown().

Compile-tested only.

Subject: ixgbe: use generic power management

With legacy PM hooks, it was the responsibility of a driver to manage PCI
states and also the device's power state. The generic approach is to let
PCI core handle the work.

ixgbe_suspend() calls __ixgbe_shutdown() to perform intermediate tasks.
__ixgbe_shutdown() modifies the value of "wake" (device should be wakeup
enabled or not), responsible for controlling the flow of legacy PM.

Since, PCI core has no idea about the value of "wake", new code for generic
PM may produce unexpected results. Thus, use "device_set_wakeup_enable()"
to wakeup-enable the device accordingly.

Compile-tested only.

Subject: ixgbevf: use generic power management

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.

After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.

The driver was invoking PCI helper functions like pci_save/restore_state(),
and pci_enable/disable_device(), which is not recommended.

Subject: e100: use generic power management

With legacy PM hooks, it was the responsibility of a driver to manage PCI
states and also the device's power state. The generic approach is to let
PCI core handle the work.

e100_suspend() calls __e100_shutdown() to perform intermediate tasks.
__e100_shutdown() calls pci_save_state() which is not recommended.

e100_suspend() also calls __e100_power_off() which is calling PCI helper
functions, pci_prepare_to_sleep(), pci_set_power_state(), along with
pci_wake_from_d3(...,false). Hence, the functin call is removed and wol is
disabled as earlier using device_wakeup_disable().

Compile-tested only.

Subject: Documentation: intel: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Subject: bpf, arm64: Add BPF exception tables

When a tracing BPF program attempts to read memory without using the
bpf_probe_read() helper, the verifier marks the load instruction with
the BPF_PROBE_MEM flag. Since the arm64 JIT does not currently recognize
this flag it falls back to the interpreter.

Add support for BPF_PROBE_MEM, by appending an exception table to the
BPF program. If the load instruction causes a data abort, the fixup
infrastructure finds the exception table and fixes up the fault, by
clearing the destination register and jumping over the faulting
instruction.

To keep the compact exception table entry format, inspect the pc in
fixup_exception(). A more generic solution would add a "handler" field
to the table entry, like on x86 and s390.

Subject: bpf: Add missing newline characters in verifier error messages

Newline characters are added in two verifier error messages,
refactored in Commit afbf21dce668 ("bpf: Support readonly/readwrite
buffers in verifier"). This way, they do not mix with
messages afterwards.

Subject: selftests/bpf: Test bpf_iter buffer access with negative offset

Commit afbf21dce668 ("bpf: Support readonly/readwrite buffers
in verifier") added readonly/readwrite buffer support which
is currently used by bpf_iter tracing programs. It has
a bug with incorrect parameter ordering which later fixed
by Commit f6dfbe31e8fa ("bpf: Fix swapped arguments in calls
to check_buffer_access").

This patch added a test case with a negative offset access
which will trigger the error path.

Without Commit f6dfbe31e8fa, running the test case in the patch,
the error message looks like:
   R1_w=rdwr_buf(id=0,off=0,imm=0) R10=fp0
  ; value_sum += *(__u32 *)(value - 4);
  2: (61) r1 = *(u32 *)(r1 -4)
  R1 invalid (null) buffer access: off=-4, size=4

With the above commit, the error message looks like:
   R1_w=rdwr_buf(id=0,off=0,imm=0) R10=fp0
  ; value_sum += *(__u32 *)(value - 4);
  2: (61) r1 = *(u32 *)(r1 -4)
  R1 invalid rdwr buffer access: off=-4, size=4

Subject: bpf: Expose socket storage to BPF_PROG_TYPE_CGROUP_SOCK

This lets us use socket storage from the following hooks:

* BPF_CGROUP_INET_SOCK_CREATE
* BPF_CGROUP_INET_SOCK_RELEASE
* BPF_CGROUP_INET4_POST_BIND
* BPF_CGROUP_INET6_POST_BIND

Using existing 'bpf_sk_storage_get_proto' doesn't work because
second argument is ARG_PTR_TO_SOCKET. Even though
BPF_PROG_TYPE_CGROUP_SOCK hooks operate on 'struct bpf_sock',
the verifier still considers it as a PTR_TO_CTX.
That's why I'm adding another 'bpf_sk_storage_get_cg_sock_proto'
definition strictly for BPF_PROG_TYPE_CGROUP_SOCK which accepts
ARG_PTR_TO_CTX which is really 'struct sock' for this program type.

Subject: selftests/bpf: Verify socket storage in cgroup/sock_{create, release}

Augment udp_limit test to set and verify socket storage value.
That should be enough to exercise the changes from the previous
patch.

Check that link is NULL or proper pointer before invoking bpf_link__destroy().
Not doing this causes crash in test_progs, when cg_storage_multi selftest

Subject: selftests/bpf: Omit nodad flag when adding addresses to loopback

Setting IFA_F_NODAD flag for IPv6 addresses to add to loopback is
unnecessary. Duplicate Address Detection does not happen on loopback
device.

Also, passing 'nodad' flag to 'ip address' breaks libbpf CI, which runs in
an environment with BusyBox implementation of 'ip' command, that doesn't
understand this flag.

Subject: libbpf: Make destructors more robust by handling ERR_PTR(err) cases

Most of libbpf "constructors" on failure return ERR_PTR(err) result encoded as
a pointer. It's a common mistake to eventually pass such malformed pointers
into xxx__destroy()/xxx__free() "destructors". So instead of fixing up
clean up code in selftests and user programs, handle such error pointers in
destructors themselves. This works beautifully for NULL pointers passed to
destructors, so might as well just work for error pointers.

Subject: selftests: txtimestamp: add flag for timestamp validation tolerance.

The txtimestamp selftest sets a fixed 500us tolerance. This value was
arrived at experimentally. Some platforms have higher variances. Make
this adjustable by adding the following flag:

-t N: tolerance (usec) for timestamp validation.

Subject: l2tp: don't export __l2tp_session_unhash

When __l2tp_session_unhash was first added it was used outside of
l2tp_core.c, but that's no longer the case.

As such, there's no longer a need to export the function.  Make it
private inside l2tp_core.c, and relocate it to avoid having to declare
the function prototype in l2tp_core.h.

Since the function is no longer used outside l2tp_core.c, remove the
"__" prefix since we don't need to indicate anything special about its
expected use to callers.

Subject: l2tp: don't export tunnel and session free functions

Tunnel and session instances are reference counted, and shouldn't be
directly freed by pseudowire code.

Rather than exporting l2tp_tunnel_free and l2tp_session_free, make them
private to l2tp_core.c, and export the refcount functions instead.

In order to do this, the refcount functions cannot be declared as
inline.  Since the codepaths which take and drop tunnel and session
references are not directly in the datapath this shouldn't cause
performance issues.

Subject: l2tp: return void from l2tp_session_delete

l2tp_session_delete is used to schedule a session instance for deletion.
The function itself always returns zero, and none of its direct callers
check its return value, so have the function return void.

This change de-facto changes the l2tp netlink session_delete callback
prototype since all pseudowires currently use l2tp_session_delete for
their implementation of that operation.

Subject: l2tp: remove build_header callback in struct l2tp_session

The structure of an L2TP data packet header varies depending on the
version of the L2TP protocol being used.

struct l2tp_session used to have a build_header callback to abstract
this difference away.  It's clearer to simply choose the correct
function to use when building the data packet (and we save on the
function pointer in the session structure).

This approach does mean dereferencing the parent tunnel structure in
order to determine the tunnel version, but we're doing that in the
transmit path in any case.

Subject: l2tp: tweak exports for l2tp_recv_common and l2tp_ioctl

All of the l2tp subsystem's exported symbols are exported using
EXPORT_SYMBOL_GPL, except for l2tp_recv_common and l2tp_ioctl.

These functions alone are not useful without the rest of the l2tp
infrastructure, so there's no practical benefit to these symbols using a
different export policy.

Change these exports to use EXPORT_SYMBOL_GPL for consistency with the
rest of l2tp.

Subject: ptp: ptp_clockmatrix: update to support 4.8.7 firmware

With 4.8.7 firmware, adjtime can change delta instead of absolute time,
which greately increases snap accuracy. PPS alignment doesn't have to
be set for every single TOD change. Other minor changes includes:
adding more debug logs, increasing snap accuracy for pre 4.8.7 firmware
and supporting new tcs2bin format.

Subject: udp, bpf: Ignore connections in reuseport group after BPF sk lookup

When BPF sk lookup invokes reuseport handling for the selected socket, it
should ignore the fact that reuseport group can contain connected UDP
sockets. With BPF sk lookup this is not relevant as we are not scoring
sockets to find the best match, which might be a connected UDP socket.

Fix it by unconditionally accepting the socket selected by reuseport.

This fixes the following two failures reported by test_progs.

  # ./test_progs -t sk_lookup
  ...
  #73/14 UDP IPv4 redir and reuseport with conns:FAIL
  ...
  #73/20 UDP IPv6 redir and reuseport with conns:FAIL
  ...

Make use of the flex_array_size() helper to calculate the size of a
flexible array member within an enclosing structure.

This helper offers defense-in-depth against potential integer
overflows, while at the same time makes it explicitly clear that
we are dealing witha flexible array member.

Also, remove unnecessary pointer identifier sub_pool.

Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.

Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

Subject: net: ll_temac: Use devm_platform_ioremap_resource_byname()

platform_get_resource() may fail and return NULL, so we had better
check its return value to avoid a NULL pointer dereference a bit later
in the code. Fix it to use devm_platform_ioremap_resource_byname()
instead of calling platform_get_resource_byname() and devm_ioremap().

Fixes: 8425c41d1ef7 ("net: ll_temac: Extend support to non-device-tree platforms")

Subject: Bluetooth: use the proper scan params when conn is pending
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When an LE connection is requested and an RPA update is needed via
hci_connect_le_scan, the default scanning parameters are used rather
than the connect parameters.  This leads to significant delays in the
connection establishment process when using lower duty cycle scanning
parameters.

The patch simply looks at the pended connection list when trying to
determine which scanning parameters should be used.

Before:
< HCI Command: LE Set Extended Scan Parameters (0x08|0x0041) plen 8
                            #378 [hci0] 1659.247156
        Own address type: Public (0x00)
        Filter policy: Ignore not in white list (0x01)
        PHYs: 0x01
        Entry 0: LE 1M
          Type: Passive (0x00)
          Interval: 367.500 msec (0x024c)
          Window: 37.500 msec (0x003c)

After:
< HCI Command: LE Set Extended Scan Parameters (0x08|0x0041) plen 8
                               #39 [hci0] 7.422109

Subject: mac80211: remove the need for variable rates_idx

Currently rates_idx is being initialized with the value -1 and this
value is never read so the initialization is redundant and can be
removed. The next time the variable is used it is assigned a value
that is returned a few statements later. Just return i - 1 and
remove the need for rates_idx.

Subject: cfg80211: allow vendor dumpit to terminate by returning 0

nl80211 vendor netlink dumpit, like netlink_callback->dump, should
signal successful completion by returning 0.

Currently, that will just cause dumpit to be called again, possibly
many times until an error occurs.  Since skb->len is never going to be
0 by the time dumpit is called, the only way for dumpit to signal
completion is by returning an error.  If it returns a positive value,
the current message is cancelled, but that positive value is returned
and nl80211_vendor_cmd_dump gets called again.

Fix that by passing a return value of 0 through.

Since commit 5fe231e87372 ("cfg80211: vastly simplify locking"), the
'unlock' label at the end of 'nl80211_trigger_scan()' is useless and
misleading, because nothing is unlocked there.

Remove this label and simplify code accordingly.

Subject: mac80211: Use fallthrough pseudo-keyword

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Subject: cfg80211: allow the low level driver to flush the BSS table

The low level driver adds its own opaque information
in the BSS table in the cfg80211_bss structure.

The low level driver may need to signal that this information
is no longer relevant and needs to be recreated.
Add an API to allow the low level driver to do that.

iwlwifi needs this because it keeps there an information about
the firmware's internal clock. This is kept in mac80211's
struct ieee80211_bss::sync_device_ts.
This information is populated while we scan, we add the
internal firmware's clock to each beacon which allows us to
program the firmware correctly after association so that
it'll know when (in terms of its internal clock) the DTIM
and TBTT will happen.

When the firmware is reset this internal clock is reset as
well and ieee80211_bss::sync_device_ts is no longer accurate.

iwlwifi will call this new API any time the firmware is started.

Subject: cfg80211/mac80211: add mesh_param "mesh_nolearn" to skip path
 discovery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, before being able to forward a packet between two 802.11s
nodes, both a PLINK handshake is performed upon receiving a beacon and
then later a PREQ/PREP exchange for path discovery is performed on
demand upon receiving a data frame to forward.

When running a mesh protocol on top of an 802.11s interface, like
batman-adv, we do not need the multi-hop mesh routing capabilities of
802.11s and usually set mesh_fwding=0. However, even with mesh_fwding=0
the PREQ/PREP path discovery is still performed on demand. Even though
in this scenario the next hop PREQ/PREP will determine is always the
direct 11s neighbor node.

The new mesh_nolearn parameter allows to skip the PREQ/PREP exchange in
this scenario, leading to a reduced delay, reduced packet buffering and
simplifies HWMP in general.

mesh_nolearn is still rather conservative in that if the packet destination
is not a direct 11s neighbor, it will fall back to PREQ/PREP path
discovery.

For normal, multi-hop 802.11s mesh routing it is usually not advisable
to enable mesh_nolearn as a transmission to a direct but distant neighbor
might be worse than reaching that same node via a more robust /
higher throughput etc. multi-hop path.

Subject: cfg80211/mac80211: add connected to auth server to meshconf

Besides information about num of peerings and gate connectivity,
the mesh formation byte also contains a flag for authentication
server connectivity, that currently cannot be set in the mesh conf.
This patch adds this capability, which is necessary to implement
802.1X authentication in mesh mode.

Subject: mac80211: improve AQL tx airtime estimation

AQL does not take into account that most HT/VHT/HE traffic is A-MPDU aggregated.
Because of that, the per-packet airtime overhead is vastly overestimated.
Improve it by assuming an average aggregation length of 16 for non-legacy
traffic if not using the VO AC queue.
This should improve performance with high data rates, especially with multiple
stations

Subject: cfg80211/mac80211: avoid bss color setting in non-HE modes

Adding bss-color configuration is only valid in HE mode.
Earlier we have enabled it by default, irrespective of
capabilities/mode. Fix that.

Subject: mac80211: never drop injected frames even if normally not allowed

In ieee80211_tx_dequeue there is a check to see if the dequeued frame
is allowed in the current state. Injected frames that are normally
not allowed are being be dropped here. Fix this by checking if a
frame was injected and if so always allowing it.

Subject: mac80211: use same flag everywhere to avoid sequence number overwrite

Use the IEEE80211_TX_CTRL_NO_SEQNO flag in ieee80211_tx_info to mark
probe requests whose sequence number must not be overwritten. This
provides consistency with the radiotap flag that can be set to indicate
that the sequence number of an injected frame should not be overwritten.

Subject: mac80211: parse radiotap header when selecting Tx queue

Already parse the radiotap header in ieee80211_monitor_select_queue.
In a subsequent commit this will allow us to add a radiotap flag that
influences the queue on which injected packets will be sent.

This also fixes the incomplete validation of the injected frame in
ieee80211_monitor_select_queue: currently an out of bounds memory
access may occur in in the called function ieee80211_select_queue_80211
if the 802.11 header is too small.

Note that in ieee80211_monitor_start_xmit the radiotap header is parsed
again, which is necessairy because ieee80211_monitor_select_queue is not
always called beforehand.

Subject: mac80211: add a function for running rx without passing skbs to the
 stack

This can be used to run mac80211 rx processing on a batch of frames in NAPI
poll before passing them to the network stack in a large batch.
This can improve icache footprint, or it can be used to pass frames via
netif_receive_skb_list.

Subject: cfg80211: invert HE BSS color 'disabled' to 'enabled'

This is in fact 'disabled' in the spec, but there it's in a
place where that actually makes sense. In our internal data
structures, it doesn't really make sense, and in fact the
previous commit just fixed a bug in that area.

Make this safer by inverting the polarity from 'disabled' to
'enabled'.

Subject: nl80211: support 4-way handshake offloading for WPA/WPA2-PSK in AP
 mode

Let drivers advertise support for AP-mode WPA/WPA2-PSK 4-way handshake
offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_AP_PSK flag.

Extend use of NL80211_ATTR_PMK attribute indicating it might be passed
as part of NL80211_CMD_START_AP command, and contain the PSK (which is
the PMK, hence the name).

The driver is assumed to handle the 4-way handshake by itself in this
case, instead of relying on userspace.

Subject: mac80211: warn only once in check_sdata_in_driver() at each caller

Ben Greear has repeatedly reported in the past (for a few years
probably) that this triggers repeatedly in certain scenarios.

Make this a macro so that each callsite can trigger the warning
only once - that will still give us an idea of what's going on
and what paths can reach it, but avoids being too noisy.

Subject: Documentation/bpf: Use valid and new links in index.rst

There exists an error "404 Not Found" when I click the html link of
"Documentation/networking/filter.rst" in the BPF documentation [1],
fix it.

Additionally, use the new links about "BPF and XDP Reference Guide"
and "bpf(2)" to avoid redirects.

Subject: netfilter: nft_compat: make sure xtables destructors have run

Pablo Neira found that after recent update of xt_IDLETIMER the
iptables-nft tests sometimes show an error.

He tracked this down to the delayed cleanup used by nf_tables core:
del rule (transaction A)
add rule (transaction B)

Its possible that by time transaction B (both in same netns) runs,
the xt target destructor has not been invoked yet.

For native nft expressions this is no problem because all expressions
that have such side effects make sure these are handled from the commit
phase, rather than async cleanup.

For nft_compat however this isn't true.

Instead of forcing synchronous behaviour for nft_compat, keep track
of the number of outstanding destructor calls.

When we attempt to create a new expression, flush the cleanup worker
to make sure destructors have completed.

With lots of help from Pablo Neira.

Subject: s390/qeth: tolerate pre-filled RX buffer

When preparing a buffer for RX refill, tolerate that it already has a
pool_entry attached. Otherwise we could easily leak such a pool_entry
when re-driving the RX refill after an error (from eg. do_qdio()).

This needs some minor adjustment in the code that drains RX buffer(s)
prior to RX refill and during teardown, so that ->pool_entry is NULLed
accordingly.

Subject: s390/qeth: integrate RX refill worker with NAPI

Running a RX refill outside of NAPI context is inherently racy, even
though the worker is only started for an entirely idle RX ring.
>From the moment that the worker has replenished parts of the RX ring,
the HW can use those RX buffers, raise an IRQ and cause our NAPI code to
run concurrently to the RX refill worker.

Instead let the worker schedule our NAPI instance, and refill the RX
ring from there. Keeping accurate count of how many buffers still need
to be refilled also removes some quirky arithmetic from the low-level
code.

Subject: s390/qeth: don't process empty bridge port events

Discard events that don't contain any entries. This shouldn't happen,
but subsequent code relies on being able to use entry 0. So better
be safe than accessing garbage.

Subject: s390/qeth: use all configured RX buffers

The (misplaced) comment doesn't make any sense, enforcing an
uninitialized RX buffer won't help with IRQ reduction.

So make the best use of all available RX buffers.

Subject: tcp: rename request_sock cookie_ts bit to syncookie

Nowadays output function has a 'synack_type' argument that tells us when
the syn/ack is emitted via syncookies.

The request already tells us when timestamps are supported, so check
both to detect special timestamp for tcp option encoding is needed.

We could remove cookie_ts altogether, but a followup patch would
otherwise need to adjust function signatures to pass 'want_cookie' to
mptcp core.

This way, the 'existing' bit can be used.

Subject: mptcp: token: move retry to caller

Once syncookie support is added, no state will be stored anymore when the
syn/ack is generated in syncookie mode.

When the ACK comes back, the generated key will be taken from the TCP ACK,
the token is re-generated and inserted into the token tree.

This means we can't retry with a new key when the token is already taken
in the syncookie case.

Therefore, move the retry logic to the caller to prepare for syncookie
support in mptcp.

Subject: mptcp: subflow: split subflow_init_req

When syncookie support is added, we will need to add a variant of
subflow_init_req() helper.  It will do almost same thing except
that it will not compute/add a token to the mptcp token tree.

To avoid excess copy&paste, this commit splits away part of the
code into a new helper, __subflow_init_req, that can then be re-used
from the 'no insert' function added in a followup change.

Subject: mptcp: subflow: add mptcp_subflow_init_cookie_req helper

Will be used to initialize the mptcp request socket when a MP_CAPABLE
request was handled in syncookie mode, i.e. when a TCP ACK containing a
MP_CAPABLE option is a valid syncookie value.

Normally (non-cookie case), MPTCP will generate a unique 32 bit connection
ID and stores it in the MPTCP token storage to be able to retrieve the
mptcp socket for subflow joining.

In syncookie case, we do not want to store any state, so just generate the
unique ID and use it in the reply.

This means there is a small window where another connection could generate
the same token.

When Cookie ACK comes back, we check that the token has not been registered
in the mean time.  If it was, the connection needs to fall back to TCP.

Changes in v2:
 - use req->syncookie instead of passing 'want_cookie' arg to ->init_req()

Subject: tcp: syncookies: create mptcp request socket for ACK cookies with
 MPTCP option

If SYN packet contains MP_CAPABLE option, keep it enabled.
Syncokie validation and cookie-based socket creation is changed to
instantiate an mptcp request sockets if the ACK contains an MPTCP
connection request.

Rather than extend both cookie_v4/6_check, add a common helper to create
the (mp)tcp request socket.

Subject: mptcp: enable JOIN requests even if cookies are in use

JOIN requests do not work in syncookie mode -- for HMAC validation, the
peers nonce and the mptcp token (to obtain the desired connection socket
the join is for) are required, but this information is only present in the
initial syn.

So either we need to drop all JOIN requests once a listening socket enters
syncookie mode, or we need to store enough state to reconstruct the request
socket later.

This adds a state table (1024 entries) to store the data present in the
MP_JOIN syn request and the random nonce used for the cookie syn/ack.

When a MP_JOIN ACK passed cookie validation, the table is consulted
to rebuild the request socket from it.

An alternate approach would be to "cancel" syn-cookie mode and force
MP_JOIN to always use a syn queue entry.

However, doing so brings the backlog over the configured queue limit.

v2: use req->syncookie, not (removed) want_cookie arg

Also add test cases with MP_JOIN when tcp_syncookies sysctl is 2 (i.e.,
syncookies are always-on).

While at it, also print the test number and add the test number
to the pcap files that can be generated optionally.

This makes it easier to match the pcap to the test case.

Subject: tcp: add earliest departure time to SCM_TIMESTAMPING_OPT_STATS

This change adds TCP_NLA_EDT to SCM_TIMESTAMPING_OPT_STATS that reports
the earliest departure time(EDT) of the timestamped skb. By tracking EDT
values of the skb from different timestamps, we can observe when and how
much the value changed. This allows to measure the precise delay
injected on the sender host e.g. by a bpf-base throttler.

Subject: rtnetlink: add support for protodown reason

netdev protodown is a mechanism that allows protocols to
hold an interface down. It was initially introduced in
the kernel to hold links down by a multihoming protocol.
There was also an attempt to introduce protodown
reason at the time but was rejected. protodown and protodown reason
is supported by almost every switching and routing platform.
It was ok for a while to live without a protodown reason.
But, its become more critical now given more than
one protocol may need to keep a link down on a system
at the same time. eg: vrrp peer node, port security,
multihoming protocol. Its common for Network operators and
protocol developers to look for such a reason on a networking
box (Its also known as errDisable by most networking operators)

This patch adds support for link protodown reason
attribute. There are two ways to maintain protodown
reasons.
(a) enumerate every possible reason code in kernel
    - A protocol developer has to make a request and
      have that appear in a certain kernel version
(b) provide the bits in the kernel, and allow user-space
(sysadmin or NOS distributions) to manage the bit-to-reasonname
map.
	- This makes extending reason codes easier (kind of like
      the iproute2 table to vrf-name map /etc/iproute2/rt_tables.d/)

This patch takes approach (b).

a few things about the patch:
- It treats the protodown reason bits as counter to indicate
active protodown users
- Since protodown attribute is already an exposed UAPI,
the reason is not enforced on a protodown set. Its a no-op
if not used.
the patch follows the below algorithm:
  - presence of reason bits set indicates protodown
    is in use
  - user can set protodown and protodown reason in a
    single or multiple setlink operations
  - setlink operation to clear protodown, will return -EBUSY
    if there are active protodown reason bits
  - reason is not included in link dumps if not used

example with patched iproute2:
$cat /etc/iproute2/protodown_reasons.d/r.conf
0 mlag
1 evpn
2 vrrp
3 psecurity

$ip link set dev vxlan0 protodown on protodown_reason vrrp on
$ip link set dev vxlan0 protodown_reason mlag on
$ip link show
14: vxlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode
DEFAULT group default qlen 1000
    link/ether f6:06:be:17:91:e7 brd ff:ff:ff:ff:ff:ff protodown on <mlag,vrrp>

$ip link set dev vxlan0 protodown_reason mlag off
$ip link set dev vxlan0 protodown off protodown_reason vrrp off

Subject: ice: mark PM functions as __maybe_unused

In certain configurations without power management support, the
following warnings happen:

drivers/net/ethernet/intel/ice/ice_main.c:4214:12: warning:
 'ice_resume' defined but not used [-Wunused-function]
 4214 | static int ice_resume(struct device *dev)

 'ice_suspend' defined but not used [-Wunused-function]
 4150 | static int ice_suspend(struct device *dev)
      |            ^~~~~~~~~~~

Mark these functions as __maybe_unused to make it clear to the
compiler that this is going to happen based on the configuration,
which is the standard for these types of functions.

Subject: ice: rename misleading grst_delay variable

The grst_delay variable in ice_check_reset contains the maximum time
(in 100 msec units) that the driver will wait for a reset event to
transition to the Device Active state. The value is the sum of three
separate components:
1) The maximum time it may take for the firmware to process its
outstanding command before handling the reset request.
2) The value in RSTCTL.GRSTDEL (the delay firmware inserts between first
seeing the driver reset request and the actual hardware assertion).
3) The maximum expected reset processing time in hardware.

Referring to this total time as "grst_delay" is misleading and
potentially confusing to someone checking the code and cross-referencing
the hardware specification.

Fix this by renaming the variable to "grst_timeout", which is more
descriptive of its actual use.

set_rss_lut can fail due to incorrect vsi_id mask. vsi_id is 10 bit
but mask was 0x1FF whereas it should be 0x3FF.

For vsi_num >= 512, FW set_rss_lut can fail with return code
EACCESS (VSI ownership issue) because software was providing
incorrect vsi_num (dropping 10th bit due to incorrect mask) for

Replacing flow profile locks with RSS profile locks in the function to

for RSS rule addition to VSI and removal during VSI teardown to avoid
a race condition owing to several iterations of the above operations.
In function to get RSS rules for given VSI and protocol header replacing
the pointer reference of the RSS entry with a copy of hash value to

Subject: ice: add useful statistics

Display and count some useful hot-path statistics. The usefulness is as
follows:

- tx_restart: use to determine if the transmit ring size is too small or
  if the transmit interrupt rate is too low.
- rx_gro_dropped: use to count drops from GRO layer, which previously were
  completely uncounted when occurring.
- tx_busy: use to determine when the driver is miscounting number of
  descriptors needed for an skb.
- tx_timeout: as our other drivers, count the number of times we've reset
  due to timeout because the kernel only prints a warning once per netdev.

Several of these were already counted but not displayed.

Subject: ice: Clear and free XLT entries on reset

This fix has been added to address memory leak issues resulting from
triggering a sudden driver reset which does not allow us to follow our
normal removal flows for SW XLT entries for advanced features.

- Adding call to destroy flow profile locks when clearing SW XLT tables.

- Extraction sequence entries were not correctly cleared previously
which could cause ownership conflicts for repeated reset-replay calls.

Subject: ice: Allow 2 queue pairs per VF on SR-IOV initialization

Currently VFs are only allowed to get 16, 4, and 1 queue pair by
default, which require 17, 5, and 2 MSI-X vectors respectively. This
is because each VF needs a MSI-X per data queue and a MSI-X for its
other interrupt. The calculation is based on the number of VFs created,
MSI-X available, and queue pairs available at the time of VF creation.

Unfortunately the values above exclude 2 queue pairs when only 3 MSI-X
are available to each VF based on resource constraints. The current
calculation would default to 2 MSI-X and 1 queue pair. This is a waste
of resources, so fix this by allowing 2 queue pairs per VF when there
are between 2 and 5 MSI-X available per VF.

Subject: ice: port fix for chk_linearlize

This is a port of commit 248de22e638f ("i40e/i40evf: Account for frags
split over multiple descriptors in check linearize")

As part of testing workloads (read/write) using larger IO size (128K)
tx_timeout is observed and whenever it happens, it was due to
tx_linearize.

In the ice_init_hw_tbls, if the devm_kcalloc for es->written fails, catch
that error and bail out gracefully, instead of continuing with a NULL
pointer.

Disable VLAN pruning when entering promiscuous mode, and re-enable it
when exiting.

Without this VLAN-over-bridge topologies created on the device won't be
functional unless rx-vlan-filter is explicitly disabled with ethtool.

Subject: ice: adjust profile ID map locks

The profile ID map lock should be held till the caller completes
all references of that profile entries.

The current code releases the lock right after the match search.
This caused a driver issue when the profile map entries were
referenced after it was freed in other thread after the lock was
released earlier.

Subject: bpf, selftests: Use single cgroup helpers for both test_sockmap/progs

Nearly every user of cgroup helpers does the same sequence of API calls. So
push these into a single helper cgroup_setup_and_join. The cases that do
a bit of extra logic are test_progs which currently uses an env variable
to decide if it needs to setup the cgroup environment or can use an
existingi environment. And then tests that are doing cgroup tests
themselves. We skip these cases for now.

From 73b11c2ab072d5b0599d1e12cc126f55ee306daf Mon Sep 17 00:00:00 2001
From: Andrii Nakryiko <andriin@fb.com>
Date: Fri, 31 Jul 2020 11:28:26 -0700
Subject: bpf: Add support for forced LINK_DETACH command

Add LINK_DETACH command to force-detach bpf_link without destroying it. It has
the same behavior as auto-detaching of bpf_link due to cgroup dying for
bpf_cgroup_link or net_device being destroyed for bpf_xdp_link. In such case,
bpf_link is still a valid kernel object, but is defuncts and doesn't hold BPF
program attached to corresponding BPF hook. This functionality allows users
with enough access rights to manually force-detach attached bpf_link without
killing respective owner process.

This patch implements LINK_DETACH for cgroup, xdp, and netns links, mostly
re-using existing link release handling code.

Subject: selftests/bpf: Fix spurious test failures in core_retro selftest

core_retro selftest uses BPF program that's triggered on sys_enter
system-wide, but has no protection from some unrelated process doing syscall
while selftest is running. This leads to occasional test failures with
unexpected PIDs being returned. Fix that by filtering out all processes that
are not test_progs process.

Fixes: fcda189a5133 ("selftests/bpf: Add test relying only on CO-RE and no recent kernel features")

The variables ant_num and single_ant_path are being initialized with a
value that is never read and are being updated later with a new value.
The initializations are redundant and can be removed.

Subject: p54: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'p54p_probe()', GFP_KERNEL can be used because
it is the probe function and no spin_lock is taken in the between.

Subject: prism54: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Subject: prism54: islpci_hotplug: use generic power management

Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.

Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions as through
the generic framework, PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

Subject: prism54: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'islpci_alloc_memory()' (islpci_dev.c),
GFP_KERNEL can be used because it is only called from a probe function
and no spin_lock is taken in the between.

The call chain is:
   prism54_probe                   (probe function, in 'islpci_hotplug.c')
      --> islpci_setup             (in 'islpci_dev.c')
         --> islpci_alloc_memory   (in 'islpci_dev.c')

Subject: rtw88: fix short GI capability based on current bandwidth

Fix the transmission is not sent with short GI under
some conditions even if the receiver supports short GI.
If VHT capability IE exists in the beacon, the original
code uses the short GI for 80M field as driver's short GI
setting for transmission, even the current bandwidth is
not 80MHz.

Short GI supported fields for 20M/40M are informed in HT
capability information element, and short GI supported
field for 80M is informed in VHT capability information
element.

These three fields may be set to different values.
Driver needs to record each short GI support field for
each bandwidth, and send correct info depends on current
bandwidth to the WiFi firmware.

Subject: rtw88: update tx descriptor of mgmt and reserved page packets

Previous settings for TX descriptors of and reserved page packets
are insufficient.

For the sequence number of packets downloaded to reserved page, it
should be filled by hardware.
And for ps-poll packets in reserved page, to prevent AID being
changed by hardware, NAVUSEHDR should be set.
Additionally, the rate should be adjusted based on the current band
for mgmt and reserved page packets.

Subject: rtw88: coex: only skip coex triggered by BT info

The coex mechanism used to skip upon the freeze flag is raised.
That will cause the coex mechanism being skipped unexpectedly.
Coex only wanted to keep the TDMA table from being changed by
BT side.

So, check the freeze and reason, if the coex reason is coming
from BT info, skip it, to make sure the coex triggered by Wifi
itself can work.

This is required for the AP mode, while the control flow is
different with STA mode. When starting an AP mode, the AP mode
needs to start working immedaitely after leaving IPS, and the
freeze flag could be raised. If the coex info is skipped, then
the AP mode will not set the antenna owner, leads to TX stuck.

Subject: rtw88: add ieee80211_ops::change_interface

Sometimes mac80211 will just ask driver to change the interface
instead of to remove and then add a new one. And for driver, to
change the interface is just simply to remove and add a new one
but change the type of it.

Subject: rtw88: 8821c: make symbol 'rtw8821c_rtw_pwr_track_tbl' static

The sparse tool complains as follows:

drivers/net/wireless/realtek/rtw88/rtw8821c.c:1374:32: warning:
 symbol 'rtw8821c_rtw_pwr_track_tbl' was not declared. Should it be static?

This variable is not used outside of rtw8821c.c, so this commit
marks it static.

Subject: rtw88: 8821c: coex: add functions and parameters

Without this patch, RTL8821CE will not have coex support,
and will crash the system because of the NULL pointers
for the coex functions.

While RTL8822C series are WiFi + BT combo chips, it needs
the co-existence mechanism for the device to work on both
WiFi and BT without interfering each other. And the coex
support has already been added before, most of the mechanisms
are implemented. The driver should just add corresponding
functions to operate on different types of chips and its
coex parameters.

Subject: iwlwifi: yoyo: don't print failure if debug firmware is missing

Missing this firmware is not fatal, my wifi card still works. Even more,
I couldn't find any documentation what it is or where to get it. So, I
don't think the users should be notified if it is missing. If you browse
the net, you see the message is present is in quite some logs. Better
remove it.

In the implementation of mt7601u_mcu_msg_send(), skb is supposed to be
consumed on all execution paths. Release skb before returning if
test_bit() fails.

Subject: rt2x00: pci: use generic power management

Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.

With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.

The callbacks make use of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device() and
pci_set_power_state() to do required operations. In generic mode, they are
no longer needed.

Change function parameter in both .suspend() and .resume() to
"struct device*" type. Use dev_get_drvdata() to get drv data.

The .suspend() callback is invoking rt2x00lib_suspend() which needs to be
modified as generic rt2x00pci_suspend() has no pm_message_t type argument,
passed to it, which is required by it according to its declaration.
Although this variable remained unused in the function body. Hence, remove
it from the function definition & declaration.

rt2x00lib_suspend() is also invoked by rt2x00usb_suspend() and
rt2x00soc_suspend(). Thus, modify the functional call accordingly in their
function body.

Earlier, .suspend() & .resume() were exported and were used by the
following drivers:
    - drivers/net/wireless/ralink/rt2x00/rt2400pci.c
    - drivers/net/wireless/ralink/rt2x00/rt2500pci.c
    - drivers/net/wireless/ralink/rt2x00/rt2800pci.c
    - drivers/net/wireless/ralink/rt2x00/rt61pci.c

Now, we only need to bind "struct dev_pm_ops" variable to
"struct pci_driver". Thus, make the callbacks static. Declare an
"extern const struct dev_pm_ops" variable and bind PM callbacks to it. Now,
export the variable instead and use it in respective drivers.

Compile-tested only.

Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:

    For each line:
      If doesn't contain `\bxmlns\b`:

            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:

Subject: b43legacy: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Subject: hostap: use generic power management

Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.

Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions as through
the generic framework, PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

Subject: ipw2100: Use GFP_KERNEL instead of GFP_ATOMIC in some memory
 allocation

The call chain is:
   ipw2100_pci_init_one            (the probe function)
     --> ipw2100_queues_allocate
       --> ipw2100_tx_allocate

No lock is taken in the between.
So it is safe to use GFP_KERNEL in 'ipw2100_tx_allocate()'.

BTW, 'ipw2100_queues_allocate()' also calls 'ipw2100_msg_allocate()' which
already allocates some memory using GFP_KERNEL.

Subject: ipw2x00: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'ipw2100_msg_allocate()' (ipw2100.c),
GFP_KERNEL can be used because it is called from the probe function.
The call chain is:
   ipw2100_pci_init_one            (the probe function)
     --> ipw2100_queues_allocate
       --> ipw2100_msg_allocate
Moreover, 'ipw2100_msg_allocate()' already uses GFP_KERNEL for some other
memory allocations.

When memory is allocated in 'status_queue_allocate()' (ipw2100.c),
GFP_KERNEL can be used because it is called from the probe function.
The call chain is:
   ipw2100_pci_init_one            (the probe function)
     --> ipw2100_queues_allocate
       --> ipw2100_rx_allocate
         --> status_queue_allocate
Moreover, 'ipw2100_rx_allocate()' already uses GFP_KERNEL for some other
memory allocations.

When memory is allocated in 'bd_queue_allocate()' (ipw2100.c),
GFP_KERNEL can be used because it is called from the probe function.
The call chain is:
   ipw2100_pci_init_one            (the probe function)
     --> ipw2100_queues_allocate
       --> ipw2100_rx_allocate
         --> bd_queue_allocate
Moreover, 'ipw2100_rx_allocate()' already uses GFP_KERNEL for some other
memory allocations.

When memory is allocated in 'ipw2100_tx_allocate()' (ipw2100.c),
GFP_KERNEL can be used because it is called from the probe function.
The call chain is:
   ipw2100_pci_init_one            (the probe function)
     --> ipw2100_queues_allocate
       --> ipw2100_tx_allocate
Moreover, 'ipw2100_tx_allocate()' already uses GFP_KERNEL for some other
memory allocations.

When memory is allocated in 'ipw_queue_tx_init()' (ipw2200.c),
GFP_KERNEL can be used because it is called from a call chain that already
uses GFP_KERNEL and no spin_lock is taken in the between.
The call chain is:
   ipw_up
     --> ipw_load
       --> ipw_queue_reset
         --> ipw_queue_tx_init
'ipw_up()' already uses GFP_KERNEL for some other memory allocations.

Subject: airo: use generic power management

Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.

Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

This makes the driver use the irqchip template to assign
properties to the gpio_irq_chip instead of using the
explicit call to gpiochip_irqchip_add().

The irqchip is instead added while adding the gpiochip.

- If the user adds a non-base chain that clashes with an existing basechain.

- If the user adds a { key : value } mapping element and the key exists

Subject: mac80211: Handle special status codes in SAE commit

SAE authentication has been extended with H2E (IEEE 802.11 REVmd) and PK
(WFA) options. Those extensions use special status code values in the
SAE commit messages (Authentication frame with transaction sequence
number 1) to identify which extension is in use. mac80211 was
interpreting those new values as the AP denying authentication and that
resulted in failure to complete SAE authentication in some cases.

Fix this by adding exceptions for the new status code values 126 and
127.

Subject: netfilter: flowtable: Set offload timeout when adding flow

On heavily loaded systems the GC can take time to go over all existing
conns and reset their timeout. At that time other calls like from
nf_conntrack_in() can call of nf_ct_is_expired() and see the conn as
expired. To fix this when we set the offload bit we should also reset
the timeout instead of counting on GC to finish first iteration over
all conns before the initial timeout.

Subject: mac80211: Do not report beacon loss if beacon filtering enabled

mac80211.h says: Beacon filter support is advertised with the
IEEE80211_VIF_BEACON_FILTER interface capability. The driver needs to
enable beacon filter support whenever power save is enabled, that is
IEEE80211_CONF_PS is set. When power save is enabled, the stack will
not check for beacon loss and the driver needs to notify about loss
of beacons with ieee80211_beacon_loss().

Some controllers may want to dynamically enable the beacon filter
capabilities on power save entry (CONF_PS) and disable it on exit.
This is the case for the wcn36xx driver which only supports beacon
filtering in PS mode (no CONNECTION_MONITOR support).

When the mac80211 beacon monitor timer expires, the beacon filter
flag must be checked again in case it as been changed in between
(e.g. vif moved to PS mode).

Subject: tools, build: Propagate build failures from
 tools/build/Makefile.build

The '&&' command seems to have a bad effect when $(cmd_$(1)) exits with
non-zero effect: the command failure is masked (despite `set -e`) and all but
the first command of $(dep-cmd) is executed (successfully, as they are mostly
printfs), thus overall returning 0 in the end.

This means in practice that despite compilation errors, tools's build Makefile
will return success. We see this very reliably with libbpf's Makefile, which
doesn't get compilation error propagated properly. This in turns causes issues
with selftests build, as well as bpftool and other projects that rely on
building libbpf.

The fix is simple: don't use &&. Given `set -e`, we don't need to chain
commands with &&. The shell will exit on first failure, giving desired
behavior and propagating error properly.

Subject: net/mlx5e: Enable users to change VF/PF representors carrier state

Currently PF and VF representor netdevice carrier is always controlled
by controlling the representor netdevice device state as up/down.

Representor netdevice state change undergoes one or more txq/rxq
destroy/create commands to firmware, skb and its rx buffer allocation,
health reporters creation and more.

Due to this limitation users do not have the ability to just change
the carrier of the non uplink representors without modifying the
device state.

In one use case when the eswitch physical port carrier is down/up,
user needs to update the VF link state to same as physical port
carrier.

Example of updating VF representor carrier state:
$ ip link set enp0s8f0npf0vf0 carrier off
$ ip link set enp0s8f0npf0vf0 carrier on

This enhancement results into VF link state change which is
represented by the VF representor netdevice carrier.

This enables users to modify the representor carrier without modifying
the representor netdevice state.

A simple test is run using [1] to calculate the time difference between
updating carrier vs updating device state (to update just the carrier)
with one VF to simulate 255 VFs.

Time taken to update the carrier using device up/down:
$ time ./calculate.sh dev enp0s8f0npf0vf0
real    0m30.913s
user    0m0.200s
sys     0m11.168s

Time taken to update just the carrier using carrier iproute2 command:
$ time ./calculate.sh carrier enp0s8f0npf0vf0
real    0m2.142s
user    0m0.160s
sys     0m2.021s

Test shows that its better to use carrier on/off user interface to notify
link up/down event to VF compare to device up/down interface, because
carrier user interface delivers the same event 15 times faster.

Subject: udp_tunnel: add the ability to hard-code IANA VXLAN

mlx5 has the IANA VXLAN port (4789) hard coded by the device,
instead of being added dynamically when tunnels are created.

To support this add a workaround flag to struct udp_tunnel_nic_info.
Skipping updates for the port is fairly trivial, dumping the hard
coded port via ethtool requires some code duplication. The port
is not a part of any real table, we dump it in a special table
which has no tunnel types supported and only one entry.

This is the last known workaround / hack needed to convert
all drivers to the new infra.

Subject: net/mlx5: convert to new udp_tunnel infrastructure

Allocate nic_info dynamically - n_entries is not constant.

Attach the tunnel offload info only to the uplink representor.
We expect the "main" netdev to be unregistered in switchdev
mode, and there to be only one uplink representor.

Drop the udp_tunnel_drop_rx_info() call, it was not there until
commit b3c2ed21c0bd ("net/mlx5e: Fix VXLAN configuration restore after function reload")
so the device doesn't need it, and core should handle reloads and
reset just fine.

v2:
 - don't drop the ndos on reprs, and register info on uplink repr.
v4:
 - Move netdev tunnel structure handling to en_main.c

Subject: net/mlx5: Delete extra dump stack that gives nothing

The WARN_*() macros are intended to catch impossible situations
from the SW point of view. They gave a little in case HW<->SW interface
is out-of-sync.

Such out-of-sync scenario can be due to SW errors that are not part
of this flow or because some HW errors, where dump stack won't help
either.

This specific WARN_ON() is useless because mlx5_core code is prepared
to handle such situations and will unfold everything correctly while
providing enough information to the users to understand why FS is not
working.

Subject: bpf: Setup socket family and addresses in bpf_prog_test_run_skb

Now it's impossible to test all branches of cgroup_skb bpf program which
accesses skb->family and skb->{local,remote}_ip{4,6} fields because they
are zeroed during socket allocation. This commit fills socket family and
addresses from related fields in constructed skb.

Subject: bpf: Allow to specify ifindex for skb in bpf_prog_test_run_skb

Now skb->dev is unconditionally set to the loopback device in current net
namespace. But if we want to test bpf program which contains code branch
based on ifindex condition (eg filters out localhost packets) it is useful
to allow specifying of ifindex from userspace. This patch adds such option
through ctx_in (__sk_buff) parameter.

Subject: dt-bindings: net: mdio: add reset-post-delay-us property

Add "reset-post-delay-us" parameter to MDIO bus properties,
so it's possible to add a delay after reset deassert.
This is optional in case external hardware slows down
release of the reset signal.

Subject: net: mdiobus: use flexible sleeping for reset-delay-us

MDIO bus reset pulse width is created by using udelay()
and that function might not be optimal depending on
device tree value. By switching to the new fsleep() helper
the correct delay function is called depending on
delay length, e.g. udelay(), usleep_range() or msleep().

Subject: net/sched: act_ct: fix miss set mru for ovs after defrag in act_ct

When openvswitch conntrack offload with act_ct action. Fragment packets
defrag in the ingress tc act_ct action and miss the next chain. Then the
packet pass to the openvswitch datapath without the mru. The over
mtu packet will be dropped in output action in openvswitch for over mtu.

"kernel: net2: dropped over-mtu packet: 1528 > 1500"

This patch add mru in the tc_skb_ext for adefrag and miss next chain
situation. And also add mru in the qdisc_skb_cb. The act_ct set the mru
to the qdisc_skb_cb when the packet defrag. And When the chain miss,
The mru is set to tc_skb_ext which can be got by ovs datapath.

Subject: openvswitch: Prevent kernel-infoleak in ovs_ct_put_key()

ovs_ct_put_key() is potentially copying uninitialized kernel stack memory
into socket buffers, since the compiler may leave a 3-byte hole at the end
of `struct ovs_key_ct_tuple_ipv4` and `struct ovs_key_ct_tuple_ipv6`. Fix
it by initializing `orig` with memset().

Subject: ipv6/addrconf: call addrconf_ifdown with consistent values

Second parameter of addrconf_ifdown "how" is used as a boolean
internally. It does not make sense to call it with something different
of 0 or 1.

This value is set to 2 in all git history.

Subject: net: bridge: clear bridge's private skb space on xmit

We need to clear all of the bridge private skb variables as they can be
stale due to the packet being recirculated through the stack and then
transmitted through the bridge device. Similar memset is already done on
bridge's input. We've seen cases where proxyarp_replied was 1 on routed
multicast packets transmitted through the bridge to ports with neigh
suppress which were getting dropped. Same thing can in theory happen with
the port isolation bit as well.

Subject: net: gre: recompute gre csum for sctp over gre tunnels

The GRE tunnel can be used to transport traffic that does not rely on a
Internet checksum (e.g. SCTP). The issue can be triggered creating a GRE
or GRETAP tunnel and transmitting SCTP traffic ontop of it where CRC
offload has been disabled. In order to fix the issue we need to
recompute the GRE csum in gre_gso_segment() not relying on the inner
checksum.
The issue is still present when we have the CRC offload enabled.
In this case we need to disable the CRC offload if we require GRE
checksum since otherwise skb_checksum() will report a wrong value.

Subject: ionic: tx separate servicing

We give the tx clean path its own budget and service routine in
order to give a little more leeway to be more aggressive, and
in preparation for coming changes.  We've found this gives us
a little better performance in some packet processing scenarios
without hurting other scenarios.

Subject: ionic: separate interrupt for Tx and Rx

Add the capability to split the Tx queues onto their own
interrupts with their own napi contexts.  This gives the
opportunity for more direct control of Tx interrupt
handling, such as CPU affinity and interrupt coalescing,
useful for some traffic loads.

v2: use ethtool -L, not a vendor specific priv-flag
v3: simplify logging, drop unnecessary "no-change" tests

Subject: cxgb4: fix check for running offline ethtool selftest

The flag indicating the selftest to run is a bitmask. So, fix the
check. Also, the selftests will fail if adapter initialization has
not been completed yet. So, add appropriate check and bail sooner.

Subject: cxgb4: fix extracting IP addresses in TC-FLOWER rules

commit c8729cac2a11 ("cxgb4: add ethtool n-tuple filter insertion")
has removed checking control key for determining IP address types
for TC-FLOWER rules, which causes all the rules being inserted to
hardware to become IPv6 rule type always. So, add back the check
to select the correct IP address type to extract and hence fix the
correct rule type being inserted to hardware.

Also, ethtool_rx_flow_key doesn't have any control key and instead
directly sets the IPv4/IPv6 address keys. So, explicitly set the
IP address type for ethtool n-tuple filters to reuse the same code.

Subject: net: Use __skb_pagelen() directly in skb_cow_data()

In fact, skb_pagelen() - skb_headlen() is equal to __skb_pagelen(), use it
directly to avoid unnecessary skb_headlen() call.

Also fix the CHECK note of checkpatch.pl:
    Comparison to NULL could be written "!__pskb_pull_tail"

Subject: net: dsa: qca8k: Add define for port VID

Rather than using a magic value of 1 when configuring the port VIDs add
a QCA8K_PORT_VID_DEF define and use that instead. Also fix up the
bitmask in the process; the top 4 bits are reserved so this wasn't a
problem, but only masking 12 bits is the correct approach.

Subject: net: dsa: qca8k: Add 802.1q VLAN support

This adds full 802.1q VLAN support to the qca8k, allowing the use of
vlan_filtering and more complicated bridging setups than allowed by
basic port VLAN support.

Tested with a number of untagged ports with separate VLANs and then a
trunk port with all the VLANs tagged on it.

v3:
- Pull QCA8K_PORT_VID_DEF changes into separate cleanup patch
- Reverse Christmas tree notation for variable definitions
- Use untagged instead of tagged for consistency
v2:
- Return sensible errnos on failure rather than -1 (rmk)
- Style cleanups based on Florian's feedback
- Silently allow VLAN 0 as device correctly treats this as no tag

Subject: atm: eni: avoid accessing the data mapped to streaming DMA

In do_tx(), skb->data is mapped to streaming DMA on line 1111:
  paddr = dma_map_single(...,skb->data,DMA_TO_DEVICE);

Then skb->data is accessed on line 1153:
  (skb->data[3] & 0xf)

This access may cause data inconsistency between CPU cache and hardware.

To fix this problem, skb->data[3] is assigned to a local variable before
DMA mapping, and then the driver accesses this local variable instead of
skb->data[3].

Subject: atm: idt77252: avoid accessing the data mapped to streaming DMA

In queue_skb(), skb->data is mapped to streaming DMA on line 850:
  dma_map_single(..., skb->data, ...);

Then skb->data is accessed on lines 862 and 863:
  tbd->word_4 = (skb->data[0] << 24) | (skb->data[1] << 16) |
           (skb->data[2] <<  8) | (skb->data[3] <<  0);
and on lines 893 and 894:
  tbd->word_4 = (skb->data[0] << 24) | (skb->data[1] << 16) |
           (skb->data[2] <<  8) | (skb->data[3] <<  0);

These accesses may cause data inconsistency between CPU cache and
hardware.

To fix this problem, the calculation result of skb->data is stored in a
local variable before DMA mapping, and then the driver accesses this
local variable instead of skb->data.

Potentially overflowing expression (ts_freq << 16 and intgr << 16)
declared as type u32 (32-bit unsigned) is evaluated using 32-bit
arithmetic and then used in a context that expects an expression of
type u64 (64-bit unsigned) which ultimately is used as 16-bit
unsigned by typecasting to u16. Fixed by using an unsigned 32-bit
integer since the value is truncated anyway in the end.

Subject: tcp: apply a floor of 1 for RTT samples from TCP timestamps

For retransmitted packets, TCP needs to resort to using TCP timestamps
for computing RTT samples. In the common case where the data and ACK
fall in the same 1-millisecond interval, TCP senders with millisecond-
granularity TCP timestamps compute a ca_rtt_us of 0. This ca_rtt_us
of 0 propagates to rs->rtt_us.

This value of 0 can cause performance problems for congestion control
modules. For example, in BBR, the zero min_rtt sample can bring the
min_rtt and BDP estimate down to 0, reduce snd_cwnd and result in a
low throughput. It would be hard to mitigate this with filtering in
the congestion control module, because the proper floor to apply would
depend on the method of RTT sampling (using timestamp options or
internally-saved transmission timestamps).

This fix applies a floor of 1 for the RTT sample delta from TCP
timestamps, so that seq_rtt_us, ca_rtt_us, and rs->rtt_us will be at
least 1 * (USEC_PER_SEC / TCP_TS_HZ).

Note that the receiver RTT computation in tcp_rcv_rtt_measure() and
min_rtt computation in tcp_update_rtt_min() both already apply a floor
of 1 timestamp tick, so this commit makes the code more consistent in
avoiding this edge case of a value of 0.

Subject: net: stmmac: fix failed to suspend if phy based WOL is enabled

With the latest net-next tree, if test suspend/resume after enabling
WOL, we get error as below:

[  487.086365] dpm_run_callback(): mdio_bus_suspend+0x0/0x30 returns -16
[  487.086375] PM: Device stmmac-0:00 failed to suspend: error -16

-16 means -EBUSY, this is because I didn't enable wakeup of the correct
device when implementing phy based WOL feature. To be honest, I caught
the issue when implementing phy based WOL and then fix it locally, but
forgot to amend the phy based wol patch. Today, I found the issue by
testing net-next tree.

Subject: devlink: Pass extack when setting trap's action and group's
 parameters

A later patch will refuse to set the action of certain traps in mlxsw
and also to change the policer binding of certain groups. Pass extack so
that failure could be communicated clearly to user space.

Use 'size_t' instead of 'u64' for array sizes, as this this is correct
type to use for expressions involving sizeof().

Subject: mlxsw: spectrum_span: On policer_id_base_ref_count, use dec_and_test

When unsetting policer base, the SPAN code currently uses refcount_dec().
However that function splats when the counter reaches zero, because
reaching zero without actually testing is in general indicative of a
missing cleanup. There is no cleanup to be done here, but nonetheless, use
refcount_dec_and_test() as required.

Subsequent patches will need to register different trap groups for
Spectrum-1 and Spectrum-2 onwards.

Enable that by invoking a per-ASIC operation during trap groups
initialization.

Subject: mlxsw: spectrum_trap: Allow for per-ASIC traps initialization

Subsequent patches will need to register different traps for Spectrum-1
and Spectrum-2 onwards.

Enable that by invoking a per-ASIC operation during traps
initialization.

Subject: mlxsw: spectrum_trap: Add early_drop trap

As previously explained, packets that are dropped due to buffer related
reasons (e.g., tail drop, early drop) can be mirrored to the CPU port.
These packets are then trapped with one of the "mirror session" traps
and their CQE includes the reason for which the packet was mirrored.

Register with devlink a new trap, early_drop, and initialize the
corresponding Rx listener with the appropriate mirror reason. Return an
error in case user tries to change the traps' action, as this is not
supported.

Since Spectrum-1 does not support these traps, the above is only done
for Spectrum-2 onwards.

Subject: mlxsw: spectrum_qdisc: Offload action trap for qevents

When offloading action trap on a qevent, pass to_dev of NULL to the SPAN
module to trigger the mirror to the CPU port. Query the buffer drops
policer and use it for policing of the trapped traffic.

Subject: mptcp: fix bogus sendmsg() return code under pressure

In case of memory pressure, mptcp_sendmsg() may call
sk_stream_wait_memory() after succesfully xmitting some

user-space the error code, ignoring the succeful xmit.

Address the issue always checking for the xmitted bytes
before mptcp_sendmsg() completes.

Subject: net: dsa: sja1105: poll for extts events from a timer

The current poll interval is enough to ensure that rising and falling
edge events are not lost for a 1 PPS signal with 50% duty cycle.

But when we deliver the events to user space, it will try to infer if
they were corresponding to a rising or to a falling edge (the kernel
driver doesn't know that either). User space will try to make that
inference based on the time at which the PPS master had emitted the
pulse (i.e. if it's a .0 time, it's rising edge, if it's .5 time, it's
falling edge).

But there is no in-kernel API for retrieving the precise timestamp
corresponding to a PPS master (aka perout) pulse. So user space has to
guess even that. It will read the PTP time on the PPS master right after
we've delivered the extts event, and declare that the PPS master time
was just the closest integer second, based on 2 thresholds (lower than
.25, or higher than .75, and ignore anything else).

Except that, if we poll for extts events (and our hardware doesn't
really help us, by not providing an interrupt), then there is a risk
that the poll period (and therefore the time at which the event is
delivered) might confuse user space.

Because we are always scheduling the next extts poll at
SJA1105_EXTTS_INTERVAL "from now" (that's the only thing that the
schedule_delayed_work() API gives us), it means that the start time of
the next delayed workqueue will always be shifted to the right a little
bit (shifted with the SPI access duration of this workqueue run).
In turn, because user space sees extts events that are non-periodic
compared to the PPS master's time, this means that it might start making
wrong guesses about rising/falling edge.

To understand the effect, here is the output of ts2phc currently. Notice
the 'src' timestamps of the 'SKIP extts' events, and how they have a
large wander. They keep increasing until the upper limit for the ignore
threshold (.75 seconds), after which the application starts ignoring the
_other_ edge.

Fix that by taking the following measures:
- Schedule the poll from a timer. Because we are really scheduling the
  timer periodically, the extts events delivered to user space are
  periodic too, and don't suffer from the "shift-to-the-right" effect.
- Increase the poll period to 6 times a second. This imposes a smaller
  upper bound to the shift that can occur to the delivery time of extts
  events, and makes user space (ts2phc) to always interpret correctly
  which events should be skipped and which shouldn't.
- Move the SPI readout itself to the main PTP kernel thread, instead of
  the generic workqueue. This is because the timer runs in atomic
  context, but is also better than before, because if needed, we can
  chrt & taskset this kernel thread, to ensure it gets enough priority
  under load.

After this patch, one can notice that the wander is greatly reduced, and
that the latencies of one extts poll are not propagated to the next. The
'src' timestamp that is skipped is never larger than .65 seconds (which
means .15 seconds larger than the time at which the real event occurred
at, and .10 seconds smaller than the .75 upper threshold for ignoring
the falling edge):

Subject: cxgb4: add TC-MATCHALL IPv6 support

Matching IPv6 traffic require allocating their own individual slots
in TCAM. So, fetch additional slots to insert IPv6 rules. Also, fetch
the cumulative stats of all the slots occupied by the Matchall rule.

Subject: dpaa2-eth: use napi_schedule to be compatible with PREEMPT_RT

The driver calls napi_schedule_irqoff() from a context where, in RT,
hardirqs are not disabled, since the IRQ handler is force-threaded.

In the call path of this function, __raise_softirq_irqoff() is modifying
its per-CPU mask of pending softirqs that must be processed, using
or_softirq_pending(). The or_softirq_pending() function is not atomic,
but since interrupts are supposed to be disabled, nobody should be
preempting it, and the operation should be safe.

Nonetheless, when running with hardirqs on, as in the PREEMPT_RT case,
it isn't safe, and the pending softirqs mask can get corrupted,
resulting in softirqs being lost and never processed.

To have common code that works with PREEMPT_RT and with mainline Linux,
we can use plain napi_schedule() instead. The difference is that
napi_schedule() (via __napi_schedule) also calls local_irq_save, which
disables hardirqs if they aren't already. But, since they already are
disabled in non-RT, this means that in practice we don't see any
measurable difference in throughput or latency with this patch.

Subject: sfc_ef100: fail the probe if NIC uses unsol_ev credits

In the future, EF100 is planned to have a credit-based scheme for
 handling unsolicited events, which drivers will need to use in order
 to function correctly.  However, current EF100 hardware does not yet
 generate unsolicited events and the credit scheme has not yet been
 implemented in firmware.  To prevent compatibility problems later if
 the current driver is used with future firmware which does implement
 it, we check for the corresponding capability flag (which that
 future firmware will set), and if found, we refuse to probe.

Subject: sfc_ef100: read Design Parameters at probe time

Several parts of the EF100 architecture are parameterised (to allow
 varying capabilities on FPGAs according to resource constraints), and
 these parameters are exposed to the driver through a TLV-encoded
 region of the BAR.
For the most part we either don't care about these values at all or
 just need to sanity-check them against the driver's assumptions, but
 there are a number of TSO limits which we record so that we will be
 able to check against them in the TX path when handling GSO skbs.

From 93f4ddd64b7dca8279ad052e0d58d92b67c33907 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Mon, 3 Aug 2020 20:23:13 -0700
Subject: via-velocity: Use more typical logging styles

Use netdev_<level> in place of VELOCITY_PRT.
Use pr_<level> in place of printk(KERN_<LEVEL>.

Miscellanea:

o Add pr_fmt to prefix pr_<level> output with "via-velocity: "
o Remove now unused functions and macros
o Realign some logging lines
o Remove devname where pr_<level> is also used

Subject: ipv4: route: Ignore output interface in FIB lookup for PMTU route

Currently, processes sending traffic to a local bridge with an
encapsulation device as a port don't get ICMP errors if they exceed
the PMTU of the encapsulated link.

David Ahern suggested this as a hack, but it actually looks like
the correct solution: when we update the PMTU for a given destination
by means of updating or creating a route exception, the encapsulation
might trigger this because of PMTU discovery happening either on the
encapsulation device itself, or its lower layer. This happens on
bridged encapsulations only.

The output interface shouldn't matter, because we already have a
valid destination. Drop the output interface restriction from the
associated route lookup.

For UDP tunnels, we will now have a route exception created for the
encapsulation itself, with a MTU value reflecting its headroom, which
allows a bridge forwarding IP packets originated locally to deliver
errors back to the sending socket.

The behaviour is now consistent with IPv6 and verified with selftests
pmtu_ipv{4,6}_br_{geneve,vxlan}{4,6}_exception introduced later in
this series.

v2:
- reset output interface only for bridge ports (David Ahern)
- add and use netif_is_any_bridge_port() helper (David Ahern)

Subject: tunnels: PMTU discovery support for directly bridged IP packets

It's currently possible to bridge Ethernet tunnels carrying IP
packets directly to external interfaces without assigning them
addresses and routes on the bridged network itself: this is the case
for UDP tunnels bridged with a standard bridge or by Open vSwitch.

PMTU discovery is currently broken with those configurations, because
the encapsulation effectively decreases the MTU of the link, and
while we are able to account for this using PMTU discovery on the
lower layer, we don't have a way to relay ICMP or ICMPv6 messages
needed by the sender, because we don't have valid routes to it.

On the other hand, as a tunnel endpoint, we can't fragment packets
as a general approach: this is for instance clearly forbidden for
VXLAN by RFC 7348, section 4.3:

   VTEPs MUST NOT fragment VXLAN packets.  Intermediate routers may
   fragment encapsulated VXLAN packets due to the larger frame size.
   The destination VTEP MAY silently discard such VXLAN fragments.

The same paragraph recommends that the MTU over the physical network
accomodates for encapsulations, but this isn't a practical option for
complex topologies, especially for typical Open vSwitch use cases.

Further, it states that:

   Other techniques like Path MTU discovery (see [RFC1191] and
   [RFC1981]) MAY be used to address this requirement as well.

Now, PMTU discovery already works for routed interfaces, we get
route exceptions created by the encapsulation device as they receive
ICMP Fragmentation Needed and ICMPv6 Packet Too Big messages, and
we already rebuild those messages with the appropriate MTU and route
them back to the sender.

Add the missing bits for bridged cases:

- checks in skb_tunnel_check_pmtu() to understand if it's appropriate
  to trigger a reply according to RFC 1122 section 3.2.2 for ICMP and
  RFC 4443 section 2.4 for ICMPv6. This function is already called by
  UDP tunnels

- a new function generating those ICMP or ICMPv6 replies. We can't
  reuse icmp_send() and icmp6_send() as we don't see the sender as a
  valid destination. This doesn't need to be generic, as we don't
  cover any other type of ICMP errors given that we only provide an
  encapsulation function to the sender

While at it, make the MTU check in skb_tunnel_check_pmtu() accurate:
we might receive GSO buffers here, and the passed headroom already
includes the inner MAC length, so we don't have to account for it
a second time (that would imply three MAC headers on the wire, but
there are just two).

This issue became visible while bridging IPv6 packets with 4500 bytes
of payload over GENEVE using IPv4 with a PMTU of 4000. Given the 50
bytes of encapsulation headroom, we would advertise MTU as 3950, and
we would reject fragmented IPv6 datagrams of 3958 bytes size on the
wire. We're exclusively dealing with network MTU here, though, so we
could get Ethernet frames up to 3964 octets in that case.

v2:
- moved skb_tunnel_check_pmtu() to ip_tunnel_core.c (David Ahern)
- split IPv4/IPv6 functions (David Ahern)

Subject: vxlan: Support for PMTU discovery on directly bridged links

If the interface is a bridge or Open vSwitch port, and we can't
forward a packet because it exceeds the local PMTU estimate,
trigger an ICMP or ICMPv6 reply to the sender, using the same
interface to forward it back.

If metadata collection is enabled, reverse destination and source
addresses, so that Open vSwitch is able to match this packet against
the existing, reverse flow.

Subject: selftests: pmtu.sh: Add tests for bridged UDP tunnels

The new tests check that IP and IPv6 packets exceeding the local PMTU
estimate, both locally generated and forwarded by a bridge from
another node, result in the correct route exceptions being created,
and that communication with end-to-end fragmentation over VXLAN and
GENEVE tunnels is now possible as a result of PMTU discovery.

Part of the existing setup functions aren't generic enough to simply
add a namespace and a bridge to the existing routing setup. This
rework is in progress and we can easily shrink this once more generic
topology functions are available.

Subject: selftests: pmtu.sh: Add tests for UDP tunnels handled by Open vSwitch

The new tests check that IP and IPv6 packets exceeding the local PMTU
estimate, forwarded by an Open vSwitch instance from another node,
result in the correct route exceptions being created, and that
communication with end-to-end fragmentation, over GENEVE and VXLAN
Open vSwitch ports, is now possible as a result of PMTU discovery.

Subject: net: thunderx: use spin_lock_bh in nicvf_set_rx_mode_task()

A dead lock was triggered on thunderx driver:

        CPU0                    CPU1
        ----                    ----
   [01] lock(&(&nic->rx_mode_wq_lock)->rlock);
                           [11] lock(&(&mc->mca_lock)->rlock);
                           [12] lock(&(&nic->rx_mode_wq_lock)->rlock);
   [02] <Interrupt> lock(&(&mc->mca_lock)->rlock);

The path for each is:

  [01] worker_thread() -> process_one_work() -> nicvf_set_rx_mode_task()
  [02] mld_ifc_timer_expire()
  [11] ipv6_add_dev() -> ipv6_dev_mc_inc() -> igmp6_group_added() ->
  [12] dev_mc_add() -> __dev_set_rx_mode() -> nicvf_set_rx_mode()

To fix it, it needs to disable bh on [1], so that the timer on [2]
wouldn't be triggered until rx_mode_wq_lock is released. So change
to use spin_lock_bh() instead of spin_lock().

Thanks to Paolo for helping with this.

v1->v2:
  - post to netdev.

Subject: net: macb: Properly handle phylink on at91sam9x

I just recently noticed that ethernet does not work anymore since v5.5
on the GARDENA smart Gateway, which is based on the AT91SAM9G25.
Debugging showed that the "GEM bits" in the NCFGR register are now
unconditionally accessed, which is incorrect for the !macb_is_gem()
case.

This patch adds the macb_is_gem() checks back to the code
(in macb_mac_config() & macb_mac_link_up()), so that the GEM register
bits are not accessed in this case any more.

Subject: hv_netvsc: do not use VF device if link is down

If the accelerated networking SRIOV VF device has lost carrier
use the synthetic network device which is available as backup
path. This is a rare case since if VF link goes down, normally
the VMBus device will also loose external connectivity as well.
But if the communication is between two VM's on the same host
the VMBus device will still work.

Subject: wan: wanxl: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'wanxl_pci_init_one()', GFP_KERNEL can be used
because it is a probe function and no lock is acquired.
Moreover, just a few lines above, GFP_KERNEL is already used.

Subject: farsync: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'fst_add_one()', GFP_KERNEL can be used
because it is a probe function and no lock is acquired.

Subject: ptp: only allow phase values lower than 1 period

The way we define the phase (the difference between the time of the
signal's rising edge, and the closest integer multiple of the period),
it doesn't make sense to have a phase value equal or larger than 1
period.

So deny these settings coming from the user.

Subject: Revert "vxlan: fix tos value before xmit"

This reverts commit 71130f29979c7c7956b040673e6b9d5643003176.

In commit 71130f29979c ("vxlan: fix tos value before xmit") we want to
make sure the tos value are filtered by RT_TOS() based on RFC1349.

       0     1     2     3     4     5     6     7
    +-----+-----+-----+-----+-----+-----+-----+-----+
    |   PRECEDENCE    |          TOS          | MBZ |
    +-----+-----+-----+-----+-----+-----+-----+-----+

But RFC1349 has been obsoleted by RFC2474. The new DSCP field defined like

       0     1     2     3     4     5     6     7
    +-----+-----+-----+-----+-----+-----+-----+-----+
    |          DS FIELD, DSCP           | ECN FIELD |
    +-----+-----+-----+-----+-----+-----+-----+-----+

So with

IPTOS_TOS_MASK          0x1E
RT_TOS(tos)		((tos)&IPTOS_TOS_MASK)

the first 3 bits DSCP info will get lost.

To take all the DSCP info in xmit, we should revert the patch and just push
all tos bits to ip_tunnel_ecn_encap(), which will handling ECN field later.

Subject: net: openvswitch: silence suspicious RCU usage warning

ovs_flow_tbl_destroy always is called from RCU callback
or error path. It is no need to check if rcu_read_lock
or lockdep_ovsl_is_held was held.

ovs_dp_cmd_fill_info always is called with ovs_mutex,
So use the rcu_dereference_ovsl instead of rcu_dereference
in ovs_flow_tbl_masks_cache_size.

Subject: tipc: set ub->ifindex for local ipv6 address

Without ub->ifindex set for ipv6 address in tipc_udp_enable(),
ipv6_sock_mc_join() may make the wrong dev join the multicast
address in enable_mcast(). This causes that tipc links would
never be created.

So fix it by getting the right netdev and setting ub->ifindex,
as it does for ipv4 address.

Subject: net: dsa: sja1105: use detected device id instead of DT one on
 mismatch

Although we can detect the chip revision 100% at runtime, it is useful
to specify it in the device tree compatible string too, because
otherwise there would be no way to assess the correctness of device tree
bindings statically, without booting a board (only some switch versions
have internal RGMII delays and/or an SGMII port).

But for testing the P/Q/R/S support, what I have is a reworked board
with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't
want to keep a separate device tree blob just for this one-off board.
Since just the chip has been replaced, its RGMII delay setup is
inherently the same (meaning: delays added by the PHY on the slave
ports, and by PCB traces on the fixed-link CPU port).

For this board, I'd rather have the driver shout at me, but go ahead and
use what it found even if it doesn't match what it's been told is there.

[    2.970826] sja1105 spi0.1: Device tree specifies chip SJA1105T but found SJA1105Q, please fix it!

Subject: selftests: rtnetlink: correct the final return value for the test

The return value "ret" will be reset to 0 from the beginning of each
sub-test in rtnetlink.sh, therefore this test will always pass if the
last sub-test has passed:

Make "ret" become a local variable for all sub-tests.
Also, check the sub-test results in kci_test_rtnl() and return the
final result for this test.

Subject: selftests: rtnetlink: make kci_test_encap() return sub-test result

kci_test_encap() is actually composed by two different sub-tests,
kci_test_encap_vxlan() and kci_test_encap_fou()

Therefore we should check the test result of these two in
kci_test_encap() to let the script be aware of the pass / fail status.
Otherwise it will generate false-negative result like below:
    $ sudo ./test.sh
    PASS: policy routing
    PASS: route get
    PASS: preferred_lft addresses have expired
    PASS: promote_secondaries complete

on some unconventional configuration.

The MPTCP protocol is trying to create a subflow for an
unaccepted server socket. That is allowed by the RFC, even
if subflow creation will likely fail.
Unaccepted sockets have still a NULL sk_socket field,
avoid the issue by failing earlier.

Subject: selftests/net: relax cpu affinity requirement in msg_zerocopy test

The msg_zerocopy test pins the sender and receiver threads to separate
cores to reduce variance between runs.

But it hardcodes the cores and skips core 0, so it fails on machines
with the selected cores offline, or simply fewer cores.

The test mainly gives code coverage in automated runs. The throughput
of zerocopy ('-z') and non-zerocopy runs is logged for manual
inspection.

Continue even when sched_setaffinity fails. Just log to warn anyone
interpreting the data.

Fixes: 07b65c5b31ce ("test: add msg_zerocopy test")

Subject: ip_tunnel_core: Fix build for archs without _HAVE_ARCH_IPV6_CSUM

On architectures defining _HAVE_ARCH_IPV6_CSUM, we get
csum_ipv6_magic() defined by means of arch checksum.h headers. On
other architectures, we actually need to include net/ip6_checksum.h
to be able to use it.

Without this include, building with defconfig breaks at least for
s390.

Subject: hso: fix bailout in error case of probe

The driver tries to reuse code for disconnect in case
of a failed probe.
If resources need to be freed after an error in probe, the
netdev must not be freed because it has never been registered.
Fix it by telling the helper which path we are in.
