Subject: cfg80211: support sysfs namespaces

Enable using network namespaces with
wireless devices even when sysfs is
enabled using the same infrastructure
that was built for netdevs.

Subject: cfg80211/mac80211: extensible frame processing

Allow userspace to register for more than just
action frames by giving the frame subtype, and
make it possible to use this in various modes
as well.

With some tweaks and some added functionality
this will, in the future, also be usable in AP
mode and be able to replace the cooked monitor
interface currently used in that case.

+/**
+ * DOC: Frame transmission/registration support
+ *
+ * Frame transmission and registration support exists to allow userspace
+ * management entities such as wpa_supplicant react to management frames
+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ *       these registrations are ignored until the interface type is
+ *       changed again. This means that changing the interface type can
+ *       lead to a situation that couldn't otherwise be produced, but
+ *       any such registrations will be dormant in the sense that they
+ *       will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.
+ *
+ * For more technical details, see the corresponding command descriptions
+ * below.

Subject: cfg80211/nl80211: introduce p2p device types

This adds P2P-STA and P2P-GO as device types so
we can distinguish between those and normal STA
or AP (respectively) type interfaces.

From 5a254ffe3ffdfa84fe076009bd8e88da412180d2 Mon Sep 17 00:00:00 2001
From: Ben Greear <greearb@candelatech.com>
Date: Mon, 27 Sep 2010 09:07:26 -0700
Subject: wireless: Use first phyX name available when registering phy devices.

Choose first available phyX name when creating phy devices.  This
means that reloading a wifi driver will not cause a change in the
name of it's phy device.

Also, allow users to rename a phy to any un-used name, including
phy%d.

From 7623225f905263424c7254dc6a07bff083a498dd Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes@sipsolutions.net>
Date: Mon, 11 Oct 2010 14:46:52 -0400
Subject: Revert "wireless: Use first phyX name available when registering phy
 devices."

This reverts commit 5a254ffe3ffdfa84fe076009bd8e88da412180d2.

The commit failed to take into account that allocated wireless devices
(wiphys) are not added into the device list upon allocation, but only
when they are registered. Therefore, it opened up a race between
allocating and registering a name, so that if two processes allocate and
register concurrently ("alloc, alloc, register, register" rather than
"alloc, register, alloc, register") the code will attempt to use the
same name twice.
