From 6962d602056c88ce470f991a265a33132fb95232 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 23 Jul 2012 14:29:21 +0200 Subject: mac80211: use oper_channel in mesh Using hw.conf.channel is wrong as it could be the temporary channel if any function like the beacon get function is called while scanning or during other temporary out-of-channel activities. Use oper_channel instead.
