      i40evf: support queue-specific settings for interrupt moderation · 65e87c03
      由 Jacob Keller 提交于 
      In commit a75e8005 ("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.

      i40e: cleanup ATR auto_disable_flags use · 234dc4e6
      由 Jacob Keller 提交于 
      Some locations that disable ATR accidentally used the "full" disable by
disabling the flag in the standard flags field. This incorrectly forces
ATR off permanently instead of temporarily disabling it. In addition,
some code locations accidentally set the ATR flag enabled when they only
meant to clear the auto_disable_flags. This results in ignoring the
user's ethtool private flag settings.

Additionally, when disabling ATR via ethtool, we did not perform a flush
of the FD table. This results in the previously assigned ATR rules still
functioning which was not expected.

Cleanup all these areas so that automatic disable uses only the
auto_disable_flag. Fix the flush code so that we can trigger a flush
even when we've disabled ATR and SB support, as otherwise the flush
doesn't work. Fix ethtool setting to actually request a flush. Fix
NETIF_F_NTUPLE flag to only clear the auto_disable setting and not
enable the full feature.

      i40e: fix setting user defined RSS hash key · f1582351
      由 Alan Brady 提交于 
      Previously, when using ethtool to change the RSS hash key, ethtool would
report back saying the old key was still being used and no error was
reported.  It was unclear whether it was being reported incorrectly or
being set incorrectly.  Debugging revealed 'i40e_set_rxfh()' returned
zero immediately instead of setting the key because a user defined
indirection table is not supplied when changing the hash key.

This fix instead changes it such that if an indirection table is not
supplied, then a default one is created and the hash key is now
correctly set.

      i40e: use priv flags to control packet split · 827de392
      由 Jesse Brandeburg 提交于 
      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.
