Subject: Re: [RFC/RFT 4/4] mac80211: use multi-queue master netdevice
Turns out there was something missing (last hunk of this updated
version) from the rt2x00 part of the patch that I accidentally didn't
quilt edit, here's an updated version if anybody wants to test on rt2x00
hw.

Subject: mac80211: use multi-queue master netdevice
This patch updates mac80211 and drivers to be multi-queue aware and
use that instead of the internal queue mapping.
Signed-off-by: Johannes Berg <johannes@...solutions.net>

This is just ground-work. We'll be able to play with Qos much more now.
