2016-02-03i40e/i40evf: Fix RSS rx-flow-hash configuration through ethtoolAnjali Singhai Jain
This patch fixes the Hash PCTYPE enable for X722 since it supports a broader selection of PCTYPES for TCP and UDP. This patch also fixes a bug in XL710, X710, X722 support for RSS, as of now we cannot reduce the (4)tuple for RSS for TCP/IPv4/IPV6 or UDP/IPv4/IPv6 packets since this requires a product feature change that comes in a later release. A VF should never be allowed to change the tuples for RSS for any PCTYPE since that's a global setting for the device in case of i40e devices.

2016-01-08i40e: Fix Rx hash reported to the stack by our driverAnjali Singhai Jain
If the driver calls skb_set_hash even with a zero hash, that indicates to the stack that the hash calculation is offloaded in hardware. So the Stack doesn't do a SW hash which is required for load balancing if the user decides to turn of rx-hashing on our device. This patch fixes the path so that we do not call skb_set_hash if the feature is disabled.

2016-01-08i40e: Look up MAC address in Open Firmware or IDPROMSowmini Varadhan
This is the i40e equivalent of commit c762dff24c06 ("ixgbe: Look up MAC address in Open Firmware or IDPROM"). As with that fix, attempt to look up the MAC address in Open Firmware on systems that support it, and use IDPROM on SPARC if no OF address is found. In the case of the i40e there is an assumption that the default mac address has already been set up as the primary mac filter on probe, so if this filter is obtained from the Open Firmware or IDPROM, an explicit write is needed via i40e_aq_mac_address_write() and i40e_aq_add_macvlan() invocation. The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure tracks whether a platform-specific mac address was found, in which case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan() will be triggered.

2015-12-15net: Rename NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASKTom Herbert
The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the set of features for offloading all checksums. This is a mask of the checksum offload related features bits. It is incorrect to set both NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for features of a device. This patch: - Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where NETIF_F_ALL_CSUM is being used as a mask). - Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to use NEITF_F_HW_CSUM in features list instead of NETIF_F_ALL_CSUM.

Mitch updates the i40evf driver by increasing the maximum number of queues, since future devices will allow for more queue pairs. Cleans up a duplicate printing of the driver info string done in init, since it is already done in probe. Cleaned up the several allocations which did not need to be at atomic level, where GFP_KERNEL would work just fine. Then makes i40e_sync_vsi_filters() a more mature function, make having a common exit point so it will properly release the busy lock on the VSI and propagate errors to the callers. Then does some whitespace housekeeping in i40evf. Kiran moves and updates the detection/recovery of transmit queue hang code to service_task from tx_timeout function. Also fixed memory leak when users program flow-director filter using ethtool (sideband filter programming), the cause being the check of 'tx_buffer->skb' was preventing 'raw_buf' from being freed as part of the cleanup. Jesse enabled the ability to turn off/on packet split using ethtool priv flags. Then does some housekeeping for both the i40e and i40evf drivers which includes: remove unused/useless code, correct whitespace, remove duplicate #include, fix incorrect comment, etc... Neerav cleans up functions to gather Flow Control Rx XOFF stats, since the recent change in the driver logic for checking transmit hang has been moved, so these functions do not do anything meaningful any longer. ==================== Signed-off-by: David S.

2015-12-03i40e: Remove separate functions gathering XOFF Rx statsNeerav Parikh
The separate functions to gather Flow control Rx XOFF stats was to determine if the Tx for a queue was paused due to Link Flow Control(LFC) or Priority Flow Control(PFC). But, with recent change in the i40e driver the logic for checking th Tx hang has been removed and these functions don't do anything meaningful. Hence, there is no need to keep these separate functions to gather Rx XOFF stats for LFC or PFC. This patch removes these functions and moves the stat collection for XOFF Rx to the i40e_update_pf_stats() that collects all the PF stats.

2015-12-03i40e: use priv flags to control packet splitJesse Brandeburg
Ethtool priv flags implementation to enable or disable packet split, which is a hardware feature that inspects headers and will put headers in a separate DMA buffer from the payload data. The driver was automatically choosing to enable packet split in some cases and this gives the user the ability to turn it off/on explicitly. to query state: ethtool --show-priv-flags ethx to enable: ethtool --set-priv-flags ethx packet-split on to disable: ethtool --set-priv-flags ethx packet-split off Why would anyone want this? Because some environments benefit from header/data split in the receive buffer, and the driver defaults to one or the other depending on environment/kernel parameters. Why didn't you implement a generic ethtool control for this feature? Because Intel hardware is the only hardware that supports header/data split.

2015-12-03i40e: propagate properlyMitch Williams
i40e_sync_vsi_filters() is the surly teenager of this driver. It says it's going to report errors, but it doesn't actually do that most of the time. And when it does, it leaves a mess. Change this function to have a common exit point so it will properly release the busy lock on the VSI. Propagate errors to the callers. Finally, adjust a few callers to check for and deal with errors from this function.

2015-12-03i40e: Fix memory leaks, sideband filter programmingKiran Patil
This patch fixes the memory leak which would be seen otherwise when user programs flow-director filter using ethtool (sideband filter programming). When ethtool is used to program flow directory filter, 'raw_buf' gets allocated and it is supposed to be freed as part of queue cleanup. But check of 'tx_buffer->skb' was preventing it from being freed.

2015-12-03i40e: Detection and recovery of TX queue hung logic moved to service_task ↵Kiran Patil
from tx_timeout This patch contains following changes: - detection and recovery logic (issue SW interrupt) has been moved to service_task from timeout function. - added some more debug info from tx_timeout. Logic to detect and recover TX queue hung is now two step process: - service_task detects TX queue hung and sets a bit(hung_detected) if it was not set. - if bit was set (means this is back-back hung condition detected), issue SW interrupt and clear the bit. - napi_poll clears the bit unconditionally since it cleans TX/RX queues.

With the final edition of the patches to remove sleeps from the driver's entry points, the grab_rtnl argument is no longer needed, so partially revert the commit that added it.

2015-12-01i40e: fix: do not sleep in netdev_opsJesse Brandeburg
The driver was being called by VLAN, bonding, teaming operations that expected to be able to hold locks like rcu_read_lock(). This causes the driver to be held to the requirement to not sleep, and was found by the kernel debug options for checking sleep inside critical section, and the locking validator.

If we get an invalid message from a VF, we should tell the user which VF is being naughty, rather than making them guess.

2015-12-01i40e: Update error messagingCarolyn Wyborny
This patch fixes an issue where adminq init failures always provided a message that NVM was newer than expected. This is not always the case for init_adminq failures. Without this patch, if adminq init fails for any reason, newer NVM message would be given. This problem is fixed by adding a check for that specific error condition and a different hopefully helpful message otherwise.
