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 2021-10-28

This series contains updates to ice driver only.

Michal adds support for eswitch drop and redirect filters from and to
tunnel devices. From meaning from uplink to VF and to means from VF to
uplink. This is accomplished by adding support for indirect TC tunnel
notifications and adding appropriate training packets and match fields
for UDP tunnel headers. He also adds returning virtchannel responses for
blocked operations as returning a response is still needed.

Marcin sets netdev min and max MTU values on port representors to allow
for MTU changes over default values.

Brett adds detecting and reporting of PHY firmware load issues for devices
which support this.

Nathan Chancellor fixes a clang warning for implicit fallthrough.

Wang Hai fixes a return value for failed allocation.
====================
