Great. I guess if you could take a look that'd be nice, and perhaps also
see if you could actually implement it? Your driver patch seemed to
imply the firmware only has global control, rather than per RA/TID.

Also, do you think A-MPDU length control would be something useful?
Perhaps that should be instead of enable/disable (since setting length
to 0 or 1 could easily mean "no A-MPDU")
