mac80211: Let userspace enable and configure vendor specific path selection.

2010-12-20T19:46:57+00:00

Userspace will now be allowed to toggle between the default path
selection algorithm (HWMP, implemented in the kernel), and a vendor
specific alternative.  Also in the same patch, allow userspace to add
information elements to mesh beacons.  This is accordance with the
Extensible Path Selection Framework specified in version 7.0 of the
802.11s draft.

cfg80211/mac80211: add mesh join/leave commands

2010-12-06T21:01:29+00:00

Instead of tying mesh activity to interface up,
add join and leave commands for mesh. Since we
must be backward compatible, let cfg80211 handle
joining a mesh if a mesh ID was pre-configured
when the device goes up.

Note that this therefore must modify mac80211 as
well since mac80211 needs to lose the logic to
start the mesh on interface up.

We now allow querying mesh parameters before the
mesh is connected, which simply returns defaults.
Setting them (internally renamed to "update") is
only allowed while connected. Specify them with
the new mesh join command instead where needed.

In mac80211, beaconing must now also follow the
mesh enabled/not enabled state, which is done
by testing the mesh ID.

net/wireless: Use pr_ and netdev_

2010-11-24T21:19:33+00:00

No change in output for pr_ prefixes.
netdev_ output is different, arguably improved.

Revert "wireless: Use first phyX name available when registering phy devices."

2010-10-11T18:46:52+00:00

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.

wireless: Use first phyX name available when registering phy devices.

2010-10-05T17:35:21+00:00

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.

cfg80211/nl80211: introduce p2p device types

2010-09-16T19:46:06+00:00

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

cfg80211/mac80211: extensible frame processing

2010-08-24T20:27:56+00:00

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.
