ath_tx_complete_aggr completes an A-MPDU frame, which typically triggers
the release of the next A-MPDU to the hw queue.
To keep track of the Block ACK window, it needs to look up the TID, for
which it needs a STA pointer. At that level, the driver typically
doesn't have access to the vif.
It might be possible to fix this by adding another sta lookup helper
function in mac80211 that takes another address argument for the BSSID,
so that it can get the sta entry for the correct vif. I don't know if
Johannes wants something like that though.
Could we just poke a pointer to the STA into the ath_buf structure?
Thanks,
Ben
