Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.

Authentication and encryption are not implemented.

There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).

A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.

Drivers that support mesh networks right now are: ath, ral and mwl.

More information at: http://wiki.freebsd.org/WifiMesh

Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.

Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.
Also, I would like to thank Gateworks Corporation for sending me a
Cambria board which was used during the development of this project.

Replace clone_setcallback() with a new function clone_setdefcallback()
that selects a callback from an interface prefix name. This allows us to
report a meaningful error when the user types 'ifconfig wlan0 create',
for example, and also kills some redundant code.

Regulatory fixups:
o add missing channel flags for ECM, indoor, and outdoor constraints
o use HT capabilities to short-circuit HT20/HT40 channel construction
o rewrite 1/2 and 1/4 width channel handling yet again; previously
we assumed there was a full-width version of the channel in the
calibration table but that's not always true (e.g. for the Public
Safety Band), now we first check the calibration table for the
exact channel we want then fall back to the heuristics we used before
o fix HT channel construction; wasn't adjusting band edges for HT40
channel bandwidth requirements

Fix 1/2 and 1/4 width channel handling:
o only include 1/2 and 1/4 width channels when they are specified in the
regulatory database description; previously we treated them as if they
were part of the band and blindly added them for 11a/g
o check the channel list returned in the devcaps to identify whether a
device supports 1/2 or 1/4 width channels on a band; this might be
better brought out as a capability bit to avoid filling the channel
list w/ 1/2 and 1/4 width channels but then cards that only support
these channels in a range of frequencies could not be described (though
right now we don't check frequency range only band)

o change ifconfig so all channel list data structures are now allocated

TDMA support for long distance point-to-point links using ath devices:
o add net80211 support for a tdma vap that is built on top of the
existing adhoc-demo support
o add tdma scheduling of frame transmission to the ath driver; it's
conceivable other devices might be capable of this too in which case
they can make use of the 802.11 protocol additions etc.
o add minor bits to user tools that need to know: ifconfig to setup and
configure, new statistics in athstats, and new debug mask bits

While the architecture can support >2 slots in a TDMA BSS the current
design is intended (and tested) for only 2 slots.
