From ad2d223aa900179031feb40273881e212941573d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 14 Dec 2012 14:34:25 +0100 Subject: mac80211: assign bss_conf.bssid only once Instead of checking every time bss_info_changed is called, assign the pointer once depending on the interface type and then leave it untouched until the interface type is changed. This makes the ieee80211_bss_info_change_notify() now a simple wrapper to call the driver only.
