The RDMA devices are operated in RoCE and iWARP modes have net device
underneath. Present their names in regular output and their net index
in detailed mode.

According to the IBTA spec [1], the physical connected port is provided
for the QP in RTR-to-INIT stage performed by modify_qp(). It causes
to do not have port number for newly created QPs.
The following patch adds "-" sign to present absence of port, because
QPs are going to be associated with rdmatool link object, which needs
port number as an index.
