Can we just increase IEEE80211_MAX_QUEUES to 64?
I think not, that would likely cause a lot of data structures to grow
too much. We'd have to do more dynamic things in that case, I suppose.
Does the original premise even make sense though? A single queue for
each vdev seems a bit strange.
Comments in ath10k claim that the approach makes per-vif tx locking
much easier and that is why that code was added....
Thanks,
