====================
Intel Wired LAN Driver Updates 2024-02-12 (i40e)

This series contains updates to i40e driver only.

Ivan Vecera corrects the looping value used while waiting for queues to
be disabled as well as an incorrect mask being used for DCB
configuration.

Maciej resolves an issue related to XDP traffic; removing a double call to
i40e_pf_rxq_wait() and accounting for XDP rings when stopping rings.
