IPoIB: Make send and receive queue sizes tunable
Make IPoIB's send and receive queue sizes tunable via module
parameters ("send_queue_size" and "recv_queue_size"). This allows the
queue sizes to be enlarged to fix disastrously bad performance on some
platforms and workloads, without bloating memory usage when large
queues aren't needed.
