893c4d6ef1 Make sure to only accept and handle action frames which are for us. In
promiscuous mode we might receive stuff which otherwise gets filtered
by hardware.

96283082bb Add a new mgmt subtype "ACTION NO ACK" defined in 802.11n-2009, while here
clean up parts of the *_recv_mgmt() functions.
- make sure appropriate counters are bumped and debug messages are printed
- order the unhandled subtypes by value and add a few missing ones
- fix some whitespace nits
- remove duplicate code in adhoc_recv_mgmt()
- remove a useless comment, probably left in while c&p

d3befdecdf Jump to the next element and not to an arbitrary point. frm[1] contains
the element's data length, frm[2] is the first byte of the element's data.

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.
