From: Johannes Berg Date: Mon, 23 Jul 2012 12:29:21 +0000 (+0200) Subject: mac80211: use oper_channel in mesh X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=6962d602056c88ce470f991a265a33132fb95232;p=~shefty%2Frdma-dev.git 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.
