Hoi Johannes,

I ma currently looking into a long standing issue with flush callback in 
brcmsmac. After some debugging I found out that mac80211 keeps pushing 
packets to brcmsmac during the flush. Is that correct? Should brcmsmac 
(or any other driver) stop the mac80211 queues during the flush? My 
assumption was that mac80211 would not do transmits during the flush, 
but it probably comes from another worker thread.
