When I connect to my Linksys WT610N AP supporting 11n I see a lot of
aggreation timeout errors:
[ 408.885053] ath6kl: aggr timeout (st 3109 end 3140)
[ 463.872108] ath6kl: aggr timeout (st 3671 end 3702)
[ 495.010060] ath6kl: aggr timeout (st 3983 end 4014)
[ 503.604047] ath6kl: aggr timeout (st 4065 end 0)
[ 518.963047] ath6kl: aggr timeout (st 141 end 172)
[ 525.014066] ath6kl: aggr timeout (st 205 end 236)
[ 573.957051] ath6kl: aggr timeout (st 701 end 732)
[ 585.019067] ath6kl: aggr timeout (st 816 end 847)
But still the connection seems to work. To not clutter the logs change
the error message to a debug message. But add a fixme comment so that
this will be investigated.
