Jacob Keller says:

====================
Intel Wired LAN Driver Updates 2023-10-19 (idpf)

This series contains two fixes for the recently merged idpf driver.

Michal adds missing logic for programming the scheduling mode of completion
queues.

Pavan fixes a call trace caused by the mailbox work item not being canceled
properly if an error occurred during initialization.
