2017-02-18i40evf: free rings in remove functionMitch Williams
When the i40evf_remove() calls netdev close, the device doesn't actually close - it schedules the work for the watchdog to perform. Since we're stopping the watchdog, this work doesn't get done. However, we're resetting the part, so we can free resources after the reset request has gone through. This plugs a memory leak.

2016-12-02i40evf: check for msix_entries null dereferenceAlan Brady
It is possible for msix_entries to be freed by a previous suspend/remove before a VF is closed. This patch fixes the issue by checking for NULL before dereferencing msix_entries and returning early in the case where it is NULL within the i40evf_close code path. Without this patch it is possible to trigger a kernel panic through NULL dereference.

2016-12-02i40evf: Be much more verbose about what we can and cannot offloadAlexander Duyck
This change makes it so that we are much more robust about defining what we can and cannot offload. Previously we were performing no checks. This should bring us up to parity with the i40e PF driver. In addition the device only supports GSO as long as the MSS is 64 or greater. We were not checking this so an MSS less than that was resulting in Tx hangs.

2016-10-28i40e/i40evf: fix interrupt affinity bugAlan Brady
There exists a bug in which a 'perfect storm' can occur and cause interrupts to fail to be correctly affinitized. This causes unexpected behavior and has a substantial impact on performance when it happens. The bug occurs if there is heavy traffic, any number of CPUs that have an i40e interrupt are pegged at 100%, and the interrupt afffinity for those CPUs is changed. Instead of moving to the new CPU, the interrupt continues to be polled while there is heavy traffic. The bug is most readily realized as the driver is first brought up and all interrupts start on CPU0. If there is heavy traffic and the interrupt starts polling before the interrupt is affinitized, the interrupt will be stuck on CPU0 until traffic stops. The bug, however, can also be wrought out more simply by affinitizing all the interrupts to a single CPU and then attempting to move any of those interrupts off while there is heavy traffic. This patch fixes the bug by registering for update notifications from the kernel when the interrupt affinity changes. When that fires, we cache the intended affinity mask. Then, while polling, if the cpu is pegged at 100% and we failed to clean the rings, we check to make sure we have the correct affinity and stop polling if we're firing on the wrong CPU. When the kernel successfully moves the interrupt, it will start polling on the correct CPU. The performance impact is minimal since the only time this section gets executed is when performance is already compromised by the CPU.

2016-09-24i40evf: support queue-specific settings for interrupt moderationJacob Keller
In commit a75e8005d506f3 ("i40e: queue-specific settings for interrupt moderation") the i40e driver gained support for setting interrupt moderation values per queue. This patch adds support for this feature to the i40evf driver as well. In addition, a few changes are made to the i40e implementation to add function header documentation comments, as well. This behaves in a similar fashion to the implementation in i40e. Thus, requesting the moderation value when no queue is provided will report queue 0 value, while setting the value without a queue will set all queues at once.

As a result we can now send data over these types of tunnels at over 20Gb/s versus the 12Gb/s that was previously possible on my system. The advantage with the i40e parts is that this offload is mostly transparent as the hardware still deals with the inner and/or outer IPv4 headers so the IP ID is still incrementing for both when this offload is performed.

2016-04-26i40e/i40evf: Clean up feature flagsAlexander Duyck
The feature flags list for i40e and i40evf is beginning to become pretty massive. I plan to add another 4 or so features to these drivers and duplicating the flags for each and every flags list is becoming a bit repetitive. The primary change here is that we now build our features list around hw_encap_features. After that we assign that to vlan_features, hw_features, and finally map that onto features. In addition we end up throwing features onto hw_encap_features that end up having no effect such as the Rx offloads and SCTP_CRC. However that should have no impact and makes things a bit easier for us as hw_encap_features is one of the less updated features maps available. For i40evf I went through and sanity checked a few features as well. Specifically RXCSUM was being set as a read-only feature which didn't make much sense. I have updated things so we can clear the NETIF_F_RXCSUM flag since that is really a software feature and not a hardware one anyway so disabling it is just a matter of ignoring the result from the hardware.

2016-04-06i40evf: properly handle VLAN featuresMitch Williams
Correctly set the VLAN feature flags after setting the rest of the netdev flags. And don't set them in hw_features, because these can't be controlled by the VF driver.

We were passing in the seed where we should just be passing false because we want the VSI table not the pf table.

2016-04-05i40evf: Add longer wait after remove moduleMitch Williams
Upon module remove, wait a little longer after requesting a reset before checking to see if the firmware responded. This change prevents double resets when the firmware is busy.

2016-04-05i40evf: Fix VLAN featuresMitch Williams
Users of ethtool were being given the mistaken impression that this driver was able to change its VLAN tagging features, and were disappointed that this was not actually the case. Implement ndo_fix_features method so that we can adjust these flags as needed to avoid false impressions.

2016-04-05i40evf: Add additional check for resetMitch Williams
If the driver happens to read a register during the time in which the device is undergoing reset, it will receive a value of 0xdeadbeef instead of a valid value. Unfortunately, the driver may misinterpret this as a valid value, especially if it's just looking for individual bits. Add an explicit check for this value when we are looking for admin queue errors, and trigger reset recovery if we find it.
