I think you do, and I think the types are AF_INET and AF_INET6. Right
now, although the interfaces are sockaddr's they become sockaddr_in by
the time you get to rdma_translate_ip. If we want to support IPv6 going
forward then I think you'll want to separate support at the top and
potentially have rdma_cm_id ops filled in the cm_id based on the address
family specified when the rdma_cm_id was created.
