Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2023-04-17 (i40e)

This series contains updates to i40e only.

Alex moves setting of active filters to occur under lock and checks/takes
error path in rebuild if re-initializing the misc interrupt vector
failed.

* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  i40e: fix i40e_setup_misc_vector() error handling
  i40e: fix accessing vsi->active_filters without holding lock
