Maybe I am missing something but I see that a devlink hot reload is
required to enforce the update?  There isn't really a de-init
required of PCI driver entities in this case for this rdma param.
But only an unplug, plug of the auxdev with new value. Intuitively
it feels more runtime-ish.

There is also a device powerof2 requirement on the maxqp which I
don't see enforceable as it stands.

This is not super-critical for the initial submission but a nice to
have. But I do want to brainstorm options..

devlink upai often seems to be an adventure, can you submit this
driver without devlink (or any other uapis) then debate how to add
them in as followup patches?
