I would prefer that you didn't submit this.
I recently tried to select a single antenna on AR9300 and it works for 30 seconds only. The subsequent calibration makes the RX signal level to drop from the usual -30/-40 dBm to -70/-80 dBm, and the transmission practically stops. With the attached patch it works, though selecting the antenna doesn't seem to have any visible effect, at least with "iw wlanX station dump" (perhaps it works for TX). I'm using ad-hoc mode: rmmod ath9k modprobe ath9k iw dev wlan0 set type ibss iw phy phyX set antenna 2
2 is a bad mask. We use bitmap, the valid masks are 1, 3, 7. -- Miaoqing
