====================
Intel Wired LAN Driver Updates 2023-12-05 (ice, i40e, iavf)

This series contains updates to ice, i40e and iavf drivers.

Michal fixes incorrect usage of VF MSIX value and index calculation for
ice.

Marcin restores disabling of Rx VLAN filtering which was inadvertently
removed for ice.

Ivan Vecera corrects improper messaging of MFS port for i40e.

Jake fixes incorrect checking of coalesce values on iavf.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  iavf: validate tx_coalesce_usecs even if rx_coalesce_usecs is zero
  i40e: Fix unexpected MFS warning message
  ice: Restore fix disabling RX VLAN filtering
  ice: change vfs.num_msix_per to vf->num_msix
