81b95c2cc7 Correct the 802.11s mesh configuration structure and related tidbits.
* Change the mesh IE size to be IEEE80211_MESH_CONF_SZ rather than the
  size of the structure;
* conf_cap is now a uint8_t rather than a uint16_t (uint16_t in D3.0,
  uint8_t in the amendment spec);
* Update mesh config capability bits - earlier bits were from draft X,
  current is amendment spec;
* Update the following to be an enum rather than #define and added
  a VENDOR entry too from the amendment spec;
  IEEE80211_MESHCONF_PATH_*
  IEEE80211_MESHCONF_METRIC_*
  IEEE80211_MESHCONF_CC_*
  IEEE80211_MESHCONF_SYNC_*
  IEEE80211_MESHCONF_AUTH_*
* Kept IEEE80211_MESHCONF_FORM_* and IEEE80211_MESHCONF_CAP_* as
  defines because they are defined in a way that we need to mask in/out
  information;
* In IEEE80211_MESHCONF_CAP_* IEEE80211_MESHCONF_CAP_TBTTA is removed
  and 0x80 is made reserved as defined in the amendment spec.

6b8c18292c Another 3.03 draft bit that I missed in the previous 802.11s stack
update. The Mesh Configuration IE has changed quite a bit. Refactor the
code to handle this change.

c77735e28f Update 802.11s mesh support to draft 3.03. This includes a revised frame
format for peering and changes to the PERR frames.
Note that this is incompatible with the previous code.

59aa14a91d 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.
