From 225b818982403120ce1f5e7d4b3e5245e0399775 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 21 Jan 2015 21:09:02 +0100 Subject: [PATCH] mac80211: support beacon statistics For drivers without beacon filtering, support beacon statistics entirely, i.e. report the number of beacons and average signal. For drivers with beacon filtering, give them the number of beacons received by mac80211 -- in case the device reports only the number of filtered beacons then driver doesn't have to count all beacons again as mac80211 already does.
