From: Johannes Berg Date: Wed, 21 Jan 2015 20:09:02 +0000 (+0100) Subject: mac80211: support beacon statistics X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=225b818982403120ce1f5e7d4b3e5245e0399775;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
