ah->caps.tx_chainmask is read from eeprom, e.g ath9k_hw_fill_cap_info(): pCap->tx_chainmask = ah->eep_ops->get_eeprom(ah, EEP_TX_MASK); Sujith, the issue was found on ap143(QCA9531, 11n, 2x2), reported by Korea team. They want to make ap143 to work on 1x2 or 2x2 mode. You can also find the changes on 10.2(ar9300_thermometer_apply).

Yes, that's true. Miaoqing, can you clarify ? Should the thermometer for chain 1 be enabled even though the HW caps contain 0x1 as TX chainmask, for example ? Are there such boards ?
