From babc305e21ea3811d98b67437299360904ac1b6a Mon Sep 17 00:00:00 2001 From: Sara Sharon Date: Mon, 21 Sep 2015 15:47:40 +0300 Subject: mac80211: reset CQM history upon reconfiguration The current behavior of notifying CQM events is inconsistent: Upon first configuration there is a cqm event with the current status according to threshold configured, regardless of signal stability. When there is reconfiguration no event is sent unless there is a significant change to the signal level according to the new configuration. Since the current reconfiguration behavior might cause missing CQM events in case the current signal did not change but is on the other side of the new threshold, fix that by resetting the stored signal level upon reconfiguration.
