Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2022-12-05 (i40e)

Michal clears XPS init flag on reset to allow for updated values to be
written.

Sylwester adds sleep to VF reset to resolve issue of VFs not getting
resources.

Przemyslaw rejects filters for raw IPv4 or IPv6 l4_4_bytes filters as they
 are not supported.

* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  i40e: Disallow ip4 and ip6 l4_4_bytes
  i40e: Fix for VF MAC address 0
  i40e: Fix not setting default xps_cpus after reset
====================
