* changing regulatory not advisable
*second number is hw specific value for the channel, we use this index
to do some HAL configuration like ANI, calibration or any other
operation in the driver code using this index for
struct ath9k_channel
*you should have hit
BUILD_BUG_ON(ARRAY_SIZE(ath9k_2ghz_chantable) +
ARRAY_SIZE(ath9k_5ghz_chantable) !=
ATH9K_NUM_CHANNELS);
