From ff36041652fcb9f5c17bdbeb081414f69521f1af Mon Sep 17 00:00:00 2001 From: Vasanthakumar Thiagarajan <vasanth@atheros.com> Date: Thu, 20 Aug 2009 13:41:14 +0530 Subject: 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.
