And then we come full circle back to the queue mappings of course --
when the channel context is assigned, the driver is able to change the
queue details in the vif to map to whatever it needs, if anything
different. Like I said in the other email, some devices may use queues
for each interface regardless of channel (e.g. wl12xx, from discussions
with them) while others (ath9k at least, I suspect) would use queues per
channel context. For iwlwifi, I'm not sure yet.
