The PS and sockaddr type are linked together, it makes no sense to use a PS_TCP and a sockaddr_ib together - sockaddr_ib doesn't have a port number, or IP address. So AF_GID/IB must also use PS_IB. The real complex question is if the scheme should have a transparent way for something like rdma_get_addr_info to return a description that uses PS_IB but sets things up to be compatible with a PS_TCP listener. It would be easy to do this.. I really don't know, bypassing the IP stack so completely is really not a great idea from an administration standpoint..
