Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2022-11-09 (ice, iavf)

This series contains updates to ice and iavf drivers.

Norbert stops disabling VF queues that are not enabled for ice driver.

Michal stops accounting of VLAN 0 filter to match expectations of PF
driver for iavf.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  iavf: Fix VF driver counting VLAN 0 filters
  ice: Fix spurious interrupt during removal of trusted VF
