This patch roughly implements xmit aggregation for ar9170-like device.
Not all AP are compatible with the driver(and firmware) yet, so YMMV.
A more refined code will definitely need the final HT specification
to be available for the public, lots of firmware modification and
possibly a redesigned driver just for good measure.
Sadly, these conditions won't come true anytime soon...
