RDS has a similar requirement - it creates one listener to which all
clients connect.
I'm also trying to figure out whether to use CM or CMA for Rds.

I would think that rdma_accept() would create a seperate cma_id (and
it's associated qp) which will then become the actual passive side of
the connection.
