I think I pointed those out previously. Testing should show anywhere that we miss fairly quickly, since port would still be 0. For the checks that can be updated to be per port, I would rather go ahead and convert them. Got it, will be changed in next version :-) To be confirmed: PORT ASSIGNED rdma_init_qp_attr Y rdma_destroy_id unknown cma_listen_on_dev N cma_bind_loopback N rdma_listen N rdma_connect Y rdma_accept Y rdma_reject Y rdma_disconnect Y ib_ucm_add_one N Is this list correct?
