From b4bb5c3fd9333024044362df67e23e96158489ed Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 19 Apr 2010 10:48:38 +0200 Subject: mac80211: remove bogus TX agg state assignment When the addba timer expires but has no work to do, it should not affect the state machine. If it does, TX will not see the successfully established and we can also crash trying to re-establish the session.

This caused more dependence on current state to ensure driver will be notified when configuration changes occur. One such problem arises if off-channel is in progress when HT information changes. Since HT is only enabled on the "oper_channel" the driver will never be notified of this change. Usually the driver is notified soon after of a BSS information change (BSS_CHANGED_HT) ... but since the driver did not get a notification that this is a HT channel the new BSS information does not make sense. Fix this by also changing the off-channel information when HT is enabled and thus cause driver to be notified correctly. This fixes a problem in 4965 when associated with 5GHz 40MHz channel. Without this patch the system can associate but is unable to transfer any data, not even ping.
