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.
