What's open80211s?
open80211s is a reference implementation of the recently ratified 802.11s standard on Linux. open80211s is based on the mac80211 wireless stack and should run on any of the wireless cards that mac80211 supports.
Mainline integration
We are happy to announce that open80211s has been accepted in mainline Linux kernel and is included in release 2.6.26. From now on the latest development code will be available in wireless-testing. It is also possible to use open80211s without having to recompile the whole kernel using compat-wireless.
We recommend the linux-wireless mailing list for patches or questions regarding the latest code, but we will keep an eye on the open80211 mailing list as well.

Driver Status
The following drivers are known to work in open80211s mesh point mode. This list tracks drivers in wireless-testing. For drivers where mesh point support is merged in mainline, the earliest kernel version is listed.
| Driver | Supported in | Notes |
| ath5k | 2.6.29 | working |
| ath9k | wireless-testing | working (known issue: bug 14187 -- need to scan before device will beacon) |
| known issue: older cards don't configure rx filtering correctly. (for instance, AR5418 MAC/BB Rev:2 AR2122). workaround: bring up a monitor interface on the same phy to fix mesh. How to fix. | ||
| ath9k_htc | 3.0.0 | working |
| libertas_tf | 2.6.27 | working |
| p54 | 2.6.29 | working |
| rt2x00 | 2.6.30 | working (known issue: bug 13752 -- need to scan before device will beacon) |
| zd1211rw | 2.6.26 | (broken in wireless-testing?) On some systems, mesh beaconing triggers what appears to be a firmware bug. |
Support for other mac80211 drivers is also possible. Please help test or fix them with patches against wireless-testing unless noted otherwise. Please refer to the mesh section of the mac80211 driver API notes for features that need to be implemented in order for a driver to support Mesh Point mode.
