I don't think this matters. The issue at hand is that the driver still relies on mac80211 buffering. This *can* be solved, even in this piece of code I inserted here, but it'd have to keep state about the queues and then insert some hooks elsewhere. I'm pretty sure I can solve that, but don't have the time (or even hardware) to test this (easily, I have ath10k in a few routers, but ...). johannes
