2012-10-30mac80211_hwsim: allow using channel contextsJohannes Berg
To use mac80211_hwsim for testing channel contexts it has to support them, and for that it has to support hw scan and hw-remain-on-channel. Since it's pure software, the off-channel activities are really not off-channel but listening and sending on a second channel. Also, the multi-channel isn't really doing TDM, it's just on both channels at the same time. For testing purposes, you can specify the number of concurrent channels with a module parameter, it is set to one by default. When set to two or more, the userspace API for wmediumd is disabled as it has no provisions for multi-channel yet. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2012-10-29ath9k_hw: Fix concurrent tx on lower tx powerRajkumar Manoharan
Whenever WLAN receives scheduling msg from BT, it reduces tx power based on RSSI level. And then BT starts simultaneous transmission along with WLAN. Sometimes HW MAC compares tx power that is used prior to power reduction which is causing BT transmission to defer.

2012-10-29ar5523: Add new driverPontus Fuchs
This driver is for the AR5523 chipset from Atheros. It was created in 2007 by Christoph Hellwig but it was never finished. I found it a couple of months ago and after some polishing it's working pretty fine. The driver was written with the FreeBSD driver (uath) as reference, which was written with the reverse-engineered windows driver as reference, hence the feature set is very limited. Station mode only, no HW crypto offload. Signed-off-by: Pontus Fuchs <pontus.fuchs@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
