Tony Nguyen says:

====================
100GbE Intel Wired LAN Driver Updates 2022-06-30

This series contains updates to ice driver only.

Martyna adds support for VLAN related TC switchdev filters and reworks
dummy packet implementation of VLANs to enable dynamic header insertion to
allow for more rule types.

Lu Wei utilizes eth_broadcast_addr() helper over an open coded version.

Ziyang Xuan removes unneeded NULL checks.
