ath9k: implement channel utilization stats for survey
Results for the active channel are updated whenever a new survey dump is requested, the old data is kept to allow multiple processes to make their own channel utilization averages. All other channels only contain the data for the last time that the hardware was on the channel, i.e. the last scan result or other off-channel activity. Running a background scan does not clear the data for the active channel. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
