Patch #1 is actually the last of the initial iWARP submission. It has been delayed until now as I wanted to make sure that qedr supports iWARP prior to enabling iWARP device detection. iWARP changes in RDMA tree have been accepted and targeted at kernel 4.15, therefore, all iWARP fixes for this cycle are submitted to net-next.
