All in one: Your workaround was a good idea, but unfortunately it
doesn't "solve" / workaround the problem introduced with the patch
"mac80211: retry sending failed BAR frames later instead of tearing
down aggr" [1]. I don't know off any other solution at this time as to revert it.

Ok, so we've got at least one hw issue here: rt2800 is not able to report
correct ACK state of BARs :(

Whould it help, if rt2800 driver will not filter out BAR frames?
