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

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2022-09-28 (ice)

Arkadiusz implements a single pin initialization function, checking feature
bits, instead of having separate device functions and updates sub-device
IDs for recognizing E810T devices.

Martyna adds support for switchdev filters on VLAN priority field.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ice: Add support for VLAN priority filters in switchdev
  ice: support features on new E810T variants
  ice: Merge pin initialization of E810 and E810T adapters
====================
