Subject: Re: [RFC/RFT 4/4] mac80211: use multi-queue master netdevice

I've tested the following patch series:
mac80211: clean up get_tx_stats callback
mac80211: remove queue info from ieee80211_tx_status
mac80211: QoS related cleanups
mac80211: use rate index in TX control
GSO: generalize for mac80211
mac80211: use GSO for fragmentation
mac80211: use multi-queue master netdevice
My rt61 card (4 TX queues) seems to work correctly, it uses
queue 3 as default queue, and a few packets seem to go
over queue 1.
