2015-10-16i40e: Recognize 1000Base_T_Optical phy type when link is upCatherine Sullivan
1000Base_T_Optical got added to the function that figures out what is supported when link is down but not when link is up. Add it in there too so that we display the correct information.

2015-10-16i40e: reset the invalid msg counter in vf when a valid msg is receivedJingjing Wu
When the number of invalid messages from a VF is exceeded, the VF will be disabled, due to the invalid messages. This happens if other VF drivers (like DPDK) send a message through the driver's mailbox (aka virtchannel) interface, but the message is not supported by the i40e pf driver, such as CONFIG_PROMISCUOUS_MODE. This patch changes the num_invalid_msgs in struct i40e_vf to record the continuous invalid msgs, and it will be reset when a valid msg is received.

2015-10-16i40e/i40evf: moderate interrupts differentlyJesse Brandeburg
The XL710 hardware has a different interrupt moderation design that can support a limit of total interrupts per second per vector, in addition to the "number of interrupts per second" controls already established in the driver. This combination of hardware features allows us to set very low default latency settings but minimize the total CPU utilization by not making too many interrupts, should the user desire. The current driver implementation is still enabling the dynamic moderation in the driver, and only using the rx/tx-usecs limit in ethtool to limit the interrupt rate per second, by default. The new code implemented in this patch 2) adds init/use of the new "Interrupt Limit" register 3) adds ethtool knob to control/report the limits above Usage is ethtool -C ethx rx-usecs-high <value> Where <value> is number of microseconds to create a rate of 1/N interrupts per second, regardless of rx-usecs or tx-usecs values. Since there is a credit based scheme in the hardware, the rx-usecs and tx-usecs can be configured for very low latency for short bursts, but once the credit runs out the refill rate on the credits is limited by rx-usecs-high.

2015-10-16i40e: remove read/write failed messages from nvmupdateShannon Nelson
Allow the nvmupdate application to decide when a read or write error should be exposed to the user. Since the application needs to use write probes to find the ReadOnly sections on a potentially unknown NVM version in the HW and read probes to check the status of the last write, some error messages are expected, but need not be shown to the users. The driver doesn't know which are ignorable from real errors, so needs to let the application make the decision.

2015-10-16i40e/i40evf: Drop useless "IN_NETPOLL" flagAlexander Duyck
The code in i40e and i40evf is using an "IN_NETPOLL" flag that has never added any value due to the fact that the Rx clean-up is handled in NAPI. As such the flag was set, the queue was scheduled via NAPI, and then polled from the netpoll controller and if any Rx packets were processed the were processed in the wrong context. In addition the flag itself just added an unneeded conditional to the hot-path so it can safely be dropped and save us a few instructions.

Use the phy_types variable to determine what phy types are possible when link is down instead of device id as it will be more accurate. When on a backplane device, we do not support changing any settings, however we should display all the phy_types we are capable of so if we see a backplane dev ID set supported and advertised purely based on the phy_types variable.

This function should be called in place of get_link_info so that the module_types variable stays up-to-date with the rest of the link information. The EAS table does not reflect the values that are actually returned, so instead, basing these values on the Ethernet compliance codes specified in table 33 of SFF-8436 as these have been accurate.

2015-10-08i40e: refactor code to remove indentJesse Brandeburg
I found a code indent that was avoidable because a whole function is inside an if block, reverse the if and move the code back a tab.

2015-10-08i40e/i40evf: clean up some codeJesse Brandeburg
Add missings spaces after declarations, remove another __func__ use, remove uncessary braces, remove unneeded breaks, and useless returns, and generally fix up some code.

2015-10-08i40e: Support FW CEE DCB UP to TC map nibble swapGreg Bowers
Changes parsing of AQ command Get CEE DCBX OPER CFG (0x0A07). Change is required because FW creates the oper_prio_tc nibbles reversed from those in the CEE Priority Group sub-TLV.

2015-10-08i40e/i40evf: Explicitly assign enum index for VSI typeSerey Kong
Ran into an issue where PF's VSI type list was different from VF's, which was resulted in different enum index. The VSI type list can be different depending on what build flag is used for PF and VF. The change is to explicitly assign enum index for each VSI type so that PF and VF always reference to the same VSI type event if the enum lists are different.

2015-10-08i40e: add switch for link pollingShannon Nelson
There's been some need for controlling the periodic link polling for debugging link issues. This patch enables switching it off and on through an ethtool private flag. The link poll remains on by default, but can be turned off with ethtool --set-priv-flags p261p1 LinkPolling off and later turned back on with ethtool --set-priv-flags p261p1 LinkPolling on To check the current status, use ethtool --show-priv-flags p261p1 Change-ID: I32e4ab654ff3eec90a06cf144899971b82d71c40 Signed-off-by: Shannon Nelson <shannon.nelson@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2015-10-08i40e: Fix multiple link up messagesMatt Jared
This patch addresses an issue where multiple link up messages can be logged resulting from aq link status timing when link properties are changed (fc, speed, etc.); solved by using a single function to handle status printing and adding a mechanism to track whether link state (up or down) has actually changed.

2015-10-08i40e: Fix for extra Flow Director filter in table after errorCarolyn Wyborny
This patch fixes a problem where the PF's fdir filter table would have an entry that the hw was unable to add. This notification happens in the hot path, so instead of trying to fix it then, we note the location in the failure case and delete it during regular fdir subtask callback. Without this patch, a case can occur where an invalid entry gets replayed and a valid one is not.

2015-10-08i40e/i40evf: Store CEE DCBX DesiredCfg and RemoteCfgNeerav Parikh
This patch adds capability to query and store the CEE DCBX DesiredCfg and RemoteCfg data from the LLDP MIB. Added new member "desired_dcbx_config" in the i40e_hw data structure to hold CEE only DesiredCfg data.

2015-10-08i40e: Add parsing for CEE DCBX TLVsNeerav Parikh
This patch adds parsing for CEE DCBX TLVs from the LLDP MIB. While the driver gets the DCB CEE operational configuration from Firmware using the "Get CEE DCBX Oper Config" AQ command there is a need to get the CEE DesiredCfg Tx by firmware and DCB configuration Rx from peer; for debug and other application purposes.
