Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Tony Nguyen says:

====================
40GbE Intel Wired LAN Driver Updates 2022-01-07

This series contains updates to i40e and iavf drivers.

Karen limits per VF MAC filters so that one VF does not consume all
filters for i40e.

Jedrzej reduces busy wait time for admin queue calls for i40e.

Mateusz updates firmware versions to reflect new supported NVM images
and renames an error to remove non-inclusive language for i40e.

Yang Li fixes a set but not used warning for i40e.

Jason Wang removes an unneeded variable for iavf.

* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  iavf: remove an unneeded variable
  i40e: remove variables set but not used
  i40e: Remove non-inclusive language
  i40e: Update FW API version
  i40e: Minimize amount of busy-waiting during AQ send
  i40e: Add ensurance of MacVlan resources for every trusted VF
