In the net-next-2.6 tree, since we mark incoming packets with
skb_record_rx_queue() properly, we'll make a more favorable choice of
TX queue.

You may want to figure out what that isn't behaving well in your
case.

I don't think we should do any kind of software spreading for such
capable hardware, it defeats the whole point of supporting the
multiqueue features.
