Subject: iwmc3200wifi: invalidate keys when changing the BSSID

While associated, we have to invalidate our key cache if we clear our BSSID
through siwap.

Subject: iwmc3200wifi: cfg80211 key hooks implemetation

This patch implements the new cfg80211 privacy related hooks: add/get/set_key
and the set_default_key one.
With this implementation we can now call the wext-compat *encode* routines and
reduce our own wext code.

From 257862f3faef397f1a677ae6a5a1828fa00a97b1 Mon Sep 17 00:00:00 2001
From: Zhu Yi <yi.zhu@intel.com>
Date: Mon, 15 Jun 2009 21:59:56 +0200
Subject: iwmc3200wifi: rfkill cleanup

The patch cleans up the unused rfkill related structures and flags.
It also adds wext and cfg80211 handlers for txpower auto and off so
that software rfkill could be issued by user space.

From bc92afd92088ab41223383cc6863ab4792533c54 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes@sipsolutions.net>
Date: Wed, 1 Jul 2009 21:26:57 +0200
Subject: cfg80211: implement iwpower

Just on/off and timeout, and with a hacky cfg80211 method
until we figure out what we want, though this is probably
sufficient as we want to use pm_qos for wifi everywhere.

From 0e82ffe3b90bcad72cfe80e4379946b8fb0691ca Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes@sipsolutions.net>

Subject: cfg80211: combine iwfreq implementations

Until now we implemented iwfreq for managed mode, we
needed to keep the implementations separate, but now
that we have all versions implemented we can combine
them and export just one handler.

From a9a11622c5c742c115fad371c0397ae86dd3bb67 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes@sipsolutions.net>
Date: Mon, 27 Jul 2009 12:01:53 +0200
Subject: cfg80211: self-contained wext handling where possible

Finally! This is what you've all been waiting for!

This patch makes cfg80211 take care of wext emulation
_completely_ by itself, drivers that don't need things
cfg80211 doesn't do yet don't even need to be aware of
wireless extensions.
This means we can also clean up mac80211's and iwm's
Kconfig and make it possible to build them w/o wext
now!

		RIP wext.
