* Add initial support for MIMO statistics to net80211.Adrian Chadd2011-04-081-3/+9
| | | | | | | | | | | | | | | | | | | | | This introduces struct ieee80211_rx_stats - which stores the various kinds of RX statistics which a MIMO and non-MIMO 802.11 device can export. It also fleshes out the mimo export to userland (node_getmimoinfo()). It assumes that MIMO radios (for now) export both ctl and ext channels. Non-11n MIMO radios are possible (and I believe Atheros made at least one), so if that chipset support is added, extra flags to the struct ieee80211_rx_stats can be added to extend this support. Two new input functions have been added - ieee80211_input_mimo() and ieee80211_input_mimo_all() - which MIMO-aware devices can call with MIMO specific statistics. 802.11 devices calling the non-MIMO input functions will still function.

* Implementation of the upcoming Wireless Mesh standard, 802.11s, on theRui Paulo2009-07-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
