From 7e9debe9789456426ec8574ead879e33da19ee57 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 15 Jun 2009 13:42:25 +0200 Subject: mac80211: disconnect when user changes channel If we do not disconnect when a channel switch is requested, we end up eventually detection beacon loss from the AP and then disconnecting, without ever really telling the AP, so we might just as well disconnect right away. Additionally, this fixes a problem with iwlwifi where the driver will clear some internal state on channel changes like this and then get confused when we actually go clear that state from mac80211. It may look like this patch drops the no-IBSS check, but that is already handled by cfg80211 in the wext handler it provides for IBSS (cfg80211_ibss_wext_siwfreq).
