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

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2024-04-16 (ice)

This series contains updates to ice driver only.

Michal fixes a couple of issues with TC filter parsing; always add match
for src_vsi and remove flag check that could prevent addition of valid
filters.

Marcin adds additional checks for unsupported flower filters.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  ice: Fix checking for unsupported keys on non-tunnel device
  ice: tc: allow zero flags in parsing tc flower
  ice: tc: check src_vsi in case of traffic from VF
