You are talking about ar9003_phy.c -> ar9003_hw_set_chain_masks? No, the
device is 3x3 and ah->caps.tx_chainmask & ah->caps.rx_chainmask are 7 and not
5. The AR_PHY_ANALOG_SWAP := AR_PHY_SWAP_ALT_CHAIN is only done when one of
them would be 5. But I am not really sure what this register setting is really
doing. Maybe you can explain it when you think it could be related. Thanks
"0x5" chainmask is an invalid mask for AR9300 - for all revisions, including AR9580.
If a 2-stream card is required based on AR9300 for custom designs, the only
way is to use Chain 0 and Chain 2, since there are HW limitations with Chain 1.
In this case, a chainmask of 0x7 has to be used and the middle chain disabled in the
driver. This is done by a few vendors who use the 5Ghz AR9580 radio but want 2x2
instead of the usual 3x3.

Hi Sujith
I'm in the position where i want to use a 9390 as 2x2 instead of 3x3.
I use backports-3.12-1.
I've set the rx and tx mask in eeprom to 0x5.
Every 30 seconds there is a short disconnect.
Enabling some logging in
echo "0x0000050C" > /sys/kernel/debug/ieee80211/phy0/ath9k/debug
shows that something seems to go wrong during noise calibration. (See
attached log).
What seems odd to me, that for IQ cal it tries to calibrate chain 1
instead of chain 2.
Best regards
Matthias May
