Just curious: what takes care of draining SRQs when we unregister them
after all queues are gone?
Conversely, I would think that a consumer that uses SRQ
would want a similar drain mechanism to guarantee there
are no more posted Receives for the associated QP, and
thus it is safe to destroy it.
I don't think there is anything now that handles draining an SRQ, nor
ensuring a QP's RQEs are completed/consumed from its SRQ when draining
the QP. Sounds like work is needed here.
But are there any kernel SRQ consumers at this point?
