Ok, the more I ponder this, the more I like it. It has a very nice side
benefit for virtio_net: we can xmit a whole bunch of packets before notifying
the host. Real NICs might gain similarly.
The bit I can't see is what to do about qdisc if the driver manages its own
queue(s). Leave the qdisc as currently in place and have the driver call
dev_dequeue_skb() (or some wrapper) directly? Modulo locking issues, that
should be a fairly simple change.
Thanks,
Rusty.
