I was using TCP before on 3.3.0-rc5+...
I upgraded to 3.3.0-rc6+, and saw around 10Mbps performance.
I tried 3.0.23 and saw around 19Mbps.

And, I tried UDP on the 3.3.0-rc6+ and it runs a full
20Mbps with a few drops.  I still see lots of RX-CRC and
some RX-Frame errors reported by the NIC
(as seen in /debug/ieee80211/wiphy0/ath9k/recv),
but maybe things aren't as bad as they first appeared.

The stations are still bouncing around in their rate
control algorithm..typically under 200Mbps (NIC should
support up to 450Mbps), however.

The signal stays at around -12, and noise seems a constant -88.

Thanks,
Ben
