From 541a45a142df281c974d74eac2066138fc107b23 Mon Sep 17 00:00:00 2001 From: Bruno Randolf Date: Thu, 2 Dec 2010 19:12:43 +0900 Subject: nl80211/mac80211: Report signal average Extend nl80211 to report an exponential weighted moving average (EWMA) of the signal value. Since the signal value usually fluctuates between different packets, an average can be more useful than the value of the last packet. This uses the recently added generic EWMA library function. -- v2: fix ABI breakage and change factor to be a power of 2. Signed-off-by: Bruno Randolf Signed-off-by: John W.
