I could help you take care of the scheduler part if someone
else takes care of the drivers and mac80211.
Roughly what they need to do is:
- use alloc_netdev_mq instead of alloc_netdev
- use netif_{start,stop,wake}_subqueue instead of the wireless
equivalents
- when all subqueues are stopped the global queue should be stopped
in the usual way (netif_stop_queue), when at least one is active
the global queue should be woken
- use skb->queue_mapping instead of skb->priority to get the HW
queue
The scheduler part mainly consists of offering a clean way to install
a different default qdisc than pfifo_fast and adding a default
classifier. I'm presuming the wme classifier would also be useful
for other (non-mac80211) wireless drivers that offer multiple queues,
so it should probably be completely seperated from mac80211 and moved
to net/sched.
