Because that can change on the fly and should not effect on
the number of logical completion vectors rxe exposes.

BTW, what will be the affect of this if rxe driver doesn't use the
comp_vector parameter in create_cq()?
Some ULPs won't create more queue-pairs than what the rdma device
supports (per multi-queue session). One example for that exists in a
patch set I submitted for exposing to ULPs IRQ affinity mappings
through the RDMA core so they in turn can make smart assignment
decisions for queue<->cpu mappings in a multi-queue environment.
I think its safe to assume that any modern HCA drivers supports a fair
share of completion vectors.
