From: Sujith Manoharan Date: Fri, 17 Oct 2014 07:40:26 +0530 Subject: [PATCH] ath9k: Fix RoC expiration mac80211 has to be notified when a RoC period expires in the driver. In MCC mode, since the offchannel/RoC timer is set with the requested duration, ieee80211_remain_on_channel_expired() needs to be called when the timer expires. But, currently it is done after we move back to the operating channel. This is incorrect - fix this by calling ieee80211_remain_on_channel_expired() when the RoC timer expires and in ath_roc_complete() when the RoC request is aborted.
