The ring buffer is only used to pass meta data for outbound packets. The actual payload is accessed by DMA from the host. So the stop/wake queue mechanism based on counting and comparing number of pages sent v.s. number of pages in the ring buffer is wrong. Also, there is a race condition in the stop/wake queue calls, which can stop xmit queue forever. The new stop/wake queue mechanism is based on the actual bytes used by outbound packets in the ring buffer. The check for number of outstanding sends after stop queue prevents the race condition that can cause wake queue happening earlier than stop queue.
