I said Linux doesn't follow the spec, so quoting the spec doesn't help :) In Linux we do not use IB_QP_PORT information, for any QP type. I mean this very literally, go in the code and look, there is no useful access to qp->port. I did check. For connected we require the port numbers to be present in each of the AVs during modify_qp. For unconnected we require the port numbers to be provided when creating the AH, and we do not limit the acceptable port numbers to the IB_QP_PORT value. So the IB_QP_PORT has no purpose in the Linux API, from what I can see, and should never be used by any code.
