From 9b8648704358e42f9865cd6de7cedb5ac0db67e7 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 26 Jul 2012 14:38:32 +0200 Subject: [PATCH] mac80211: check operating channel in scan The optimisation of scanning only on the current channel should check the operating channel. Also modify it to compare channel pointer rather than the frequency.
