* mac80211: set HT channel before associationJohannes Berg2012-04-101-7/+3
| | | | | | | | | | | | | | | | | | | | | Changing the channel type during operation is confusing to some drivers and will be hard to handle in multi-channel scenarios. Instead of changing the channel, set it to the right HT channel before authenticating/associating and don't change it -- just update the 20/40 MHz restrictions in rate control as needed when changed by the AP. This also fixes a problem that Paul missed in his fix for the "regulatory makes us deaf" issue -- when we couldn't use 40 MHz we still associated saying we were using 40 MHz, which could in similarly broken APs make us never even connect successfully.

* mac80211: add auth/assoc/deauth flow diagramJohannes Berg2012-03-121-0/+99
I've been working on some documentation, so let's add this diagram to the kernel tree where at least it has a chance of being maintained :-) Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
