OK, so you let them do all or nothing, but this three-way test is
pretty unclear.
In fact, the whole total_queue_pairs/num_queue_pairs thing is weird (and
uncommented). I think for "total" you mean "max"; the maximum possible
queue pair number.
Let me go back and review the previous patch again...
Cheers,
