I have been carrying this patch out of tree for a while, this
refreshes it for linux 3.7.1.
I have subsequent patches that add this facility to *fq_codel,
pfifo_fast, and elsewhere.
It seemed to help somewhat when flooding the box, however I see all
sorts of interesting packet fragmentation/defragmentation/splitting
stuff happening throughout the 3.6 and 3.7 series of network stack and
I have no idea if it's as useful as all that, so I'm willing to drop
it and see what happens...
What I'd like better though is a multi-exit form of fq_codel that only
used one queue allocation for the 4 (or 5 if you count multicast)
queues in wifi... but next up is to port forward the prototype to
