From 4797c7ba93e4049cdda18045c01bbe563aafff69 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 26 Jul 2012 14:31:19 +0200 Subject: [PATCH] mac80211: use RX status band instead of current band Even for single-channel devices it is possible that we switch the channel temporarily (e.g. for scanning) but while doing so process a received frame that was still received on the old channel, so checking the current band is racy. Use the band from status instead.
