I am writing a driver for a curious 802.11 chip which has high-, medium-,
and low-priority transmit queues. I think that ath has additional Tx
queues, also.

Also, atw has a Tx queue for traffic that needs "contention-free"
service. There are rare and expensive APs which provide this service.
They reserve a period of time between each beacon where stations have to
shut up until the AP polls them. Packets needing a time-bounded service,
like VoIP, are usually sent in that period.

Any ideas how NetBSD can exploit these features?
