I'm already fixing this, see https://lore.kernel.org/r/5674c40151267fea1333f0eda1701b141bbaa170.camel@sip...
, and a per-AC lock inside ieee80211_handle_wake_tx_queue().
I'm not *entirely* sure per AC is sufficient given that you could technically map two ACs to the same HW queue with vif->hw_queue[]?
But again, not really sure all that complexity is still worth it.
