I don't think this is a good idea, since if it is a device workaround
it should be
implemented in the driver. That's what I tried before but according to Andreas
the patch causes a crash. But in general it should be possible to bring a
BA session down by calling ieee80211_stop_tx_ba_session from the driver.
Not sure why that'll crash :(
