ath9k_hw: fix a noise floor calibration related race condition
On AR5008-AR9002, other forms of calibration must not be started while the noise floor calibration is running, as this can create invalid readings which were sometimes not even recoverable by any further calibration attempts. This patch also ensures that the result of noise floor measurements are processed faster and also allows the result of the initial calibration on reset to make it into the NF history buffer Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
