Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue 

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2022-07-26

This series contains updates to ice driver only.

Przemyslaw corrects accounting for VF VLANs to allow for correct number
of VLANs for untrusted VF. He also correct issue with checksum offload
on VXLAN tunnels.

Ani allows for two VSIs to share the same MAC address.

Maciej corrects checked bits for descriptor completion of loopback

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  ice: do not setup vlan for loopback VSI
  ice: check (DD | EOF) bits on Rx descriptor rather than (EOP | RS)
  ice: Fix VSIs unable to share unicast MAC
  ice: Fix tunnel checksum offload with fragmented traffic
  ice: Fix max VLANs available for VF
