>
> Defer transitioning QPs to the ERR state so that the other work
> queues can be flushed. Complete software-flush setup even if the deferred
> ERR request fails, since the error CQE already guarantees whole QP
> shutdown.

> Clear pending CQEs for a kernel QP after a hardware RESET by setting
> their QIDs to zero. Discard CQEs with a zero QID.
>
> Mark deferred errors as pending when scheduling work to prevent stale
> work from moving a reset and reused QP to ERR.
