ath9k: Fix bug in retrieving average beacon rssi
Currently the beacon rssi that LPF gives is divided and rounded up by ATH_RSSI_EP_MULTIPLIER twice. This will leave the incorrect rssi in ANI. Having correct rssi in ANI fixes the connection stability at < 30dB rssi range. This patch removes the unncessary computation of average rssi over already valid average rssi. Also removes the redundant macros to find average rssi. Signed-off-by: Vasanthakumar Thiagarajan <vasanth@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
