Public bug reported:
On Azure, the RDMA device is exposed as a iWARP device. There is only
one such device in each VM, they are set at port 1.
A recent patch 5ecce4c9b17b("Check port number supplied by user verbs
cmds") starts checking on port_num in qp attributes passed from user
mode libraries. This requires that this value is correctly populated
when calling verb ib_modify_qp. Otherwise this call will fail.
The following patch fixed it. Please pick it up for linux-azure.
