From: Thomas Pedersen Date: Sun, 21 Oct 2012 02:03:10 +0000 (-0700) Subject: mac80211: mesh STAs only process mesh beacons X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9a90bc81914ee77edcd6eb7e881639b7f7bf1667;p=linux-beck.git mac80211: mesh STAs only process mesh beacons Before, a mesh STA would execute some code on behalf of AP or IBSS beacons. Since the mesh stack currently does not consider anything but other mesh STAs interesting, limit processing to just these and save a little overhead.
