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

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2024-04-03 (ice, idpf)

This series contains updates to ice and idpf drivers.

Dan Carpenter initializes some pointer declarations to NULL as needed for
resource cleanup on ice driver.

Petr Oros corrects assignment of VLAN operators to fix Rx VLAN filtering
in legacy mode for ice.

Joshua calls eth_type_trans() on unknown packets to prevent possible
kernel panic on idpf.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  idpf: fix kernel panic on unknown packet types
  ice: fix enabling RX VLAN filtering
  ice: Fix freeing uninitialized pointers
