Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Tony Nguyen says:

====================
100GbE Intel Wired LAN Driver Updates 2021-10-29

This series contains updates to ice and iavf drivers and virtchnl header
file.

Brett removes vlan_promisc argument from a function call for ice driver.
In the virtchnl header file he removes an unused, reserved define and
converts raw value defines to instead use the BIT macro.

Marcin adds syncing of MAC addresses when creating switchdev VFs to
remove error messages on link up and stops showing buffer information
for port representors to remove duplicated entries being displayed for
ice driver.

Karen introduces a helper to go from pci_dev to iavf_adapter in the
iavf driver.

Przemyslaw fixes an issue where iavf was attempting to free IRQs before
calling disable.
