From 6c55aa97359af4b503a8baf914de48f2406a895f Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Tue, 28 Aug 2007 17:01:55 -0400 Subject: [PATCH] [MAC80211]: Remove overly sticky averaging filters for rssi, signal, noise The current version of wireless statistics contains a bug in the averaging that makes the numbers be too sticky and not react to small changes. This patch removes all averaging. Signed-off-by: Larry Finger Signed-off-by: Jiri Benc Signed-off-by: John W. Linville Signed-off-by: Johannes Berg Acked-by: Michael Wu Signed-off-by: John W.
