>Description:
After the recent net80211 TX aggregation state handling changes (changing from
per-AC to per-TID), I've begun seeing these messages pop up in the log:
ath0: ath_tx_aggr_comp_aggr: tid 0 != hw tid 9
ath0: ath_tx_aggr_comp_aggr: tid 0 != hw tid 9
ath0: ath_tx_aggr_comp_aggr: tid 0 != hw tid 9

ath0: ath_tx_aggr_comp_aggr: tid 0 != hw tid 8
ath0: ath_tx_aggr_comp_aggr: tid 0 != hw tid 8
The code came over from Linux/atheros with this comment:
/* Occasionally, the MAC sends a tx status for the wrong TID. */
However, I don't recall seeing this problem whilst the TX aggregation state was
being kept per-AC, rather than per-TID.
>How-To-Repeat:
Enable ath(4) 802.11n, use as hostap, do a whole lot of aggregate traffic.
>Fix:
None yet.
