Hi Arlin,

In userspace/dapl/dapl/openib/dapl_ib_cm.c::dapls_ib_connect:

        status = ib_at_route_by_ip(
                ((struct sockaddr_in *)&conn->r_addr)->sin_addr.s_addr,
                ((struct sockaddr_in *)&conn->hca->hca_address)->sin_addr.s_addr, 
                0, 0, &conn->dapl_rt, &conn->dapl_comp, &conn->dapl_comp.req_id);

        dapl_dbg_log(DAPL_DBG_TYPE_CM, " connect: at_route ret=%d,%s req_id %d GID %016llx %016llx\n",
                     status, strerror(errno), conn->dapl_comp.req_id,
                     (unsigned long long)cpu_to_be64(conn->dapl_rt.dgid.global.subnet_prefix),
                     (unsigned long long)cpu_to_be64(conn->dapl_rt.dgid.global.interface_id) );

The GID is part of the route structure which is an output and not filled
in at completion of this call. I think that the destination and source
IP addresses would be more useful here.
