Yes. netlink and the gid table reports the netdev for all rdma devices, that is what the tests should be using. Call ibv_query_gid_table(), put every ndev_ifindex in a set, then that set is the list of every netdev index affiliated with the rdma device. if_indextoname() will convert to a string name Jason
