That's the core of the problem is that select_queue has the side effect
of setting skb->priority in mac80211, no? Maybe that side effect needs
to be removed?

Actually that makes it seem like something else should be doing packet
classification, not mac80211 in select_queue()?

Where is skb->priority actually really used in mac80211? I don't see
much?
