Well, there are still a lot of things to fix there. Right now if
frames are filtered due to the node going into power save, the driver
will treat them as a failed software retransmit. Too many of those
will equate to a dropped frame, and the TX is paused whilst the BAR is
sent out.

I bet I can fix that a bit. :-)

So I may end up being able to improve performance

I still have to track down that and make sure those frames are
properly treated as a management queue frame in the ath(4) driver.
