====================
Intel Wired LAN Driver Updates 2024-09-09 (ice, igb)

This series contains updates to ice and igb drivers.

Martyna moves LLDP rule removal to the proper uninitialization function
for ice.

Jake corrects accounting logic for FWD_TO_VSI_LIST switch filters on
ice.

Przemek removes incorrect, explicit calls to pci_disable_device() for
ice.

Michal Schmidt stops incorrect use of VSI list for VLAN use on ice.

Sriram Yagnaraman adjusts igb_xdp_ring_update_tail() to be called under
Tx lock on igb.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  igb: Always call igb_xdp_ring_update_tail() under Tx lock
  ice: fix VSI lists confusion when adding VLANs
  ice: stop calling pci_disable_device() as we use pcim
  ice: fix accounting for filters shared by multiple VSIs
  ice: Fix lldp packets dropping after changing the number of channels
