addresses that map to RDMA devices?
When looking at a case that the user defines a local interface ip addr
which it wants to work with. The application does not know if the ip
addr maps to an rdma-cm capable device (IB or iWapr) or
Assuming this is an rdma-cm capable device in a 'bad' state, the user

Will this work? Even once the port goes active, what the
