OpenWrtBuilding
OpenWrt can be built for your favorite router hardware with o11s support. You will need to build trunk with the following instructions.
You can "build it yourself" or download it from "here".
svn co svn://svn.openwrt.org/openwrt/trunk openwrt
cd openwrt
./scripts/feeds update -a
./scripts/feeds install -a
make menuconfig
e.g. for RouterBoard:
- Target System => (Atheros AR71xx/AR7240/AR913x/AR934x)
- Target Profile (Ubiquiti RouterStation)
- Kernel Modules => Wireless Drivers => kmod-ath9k
Save and exit.
Create the directory openwrt/dl and copy the compat-wireless-2.6.tar.bz2 into it
$ mkdir openwrt/dl
$ cp compat-wireless-2.6.tar.bz2 openwrt/dl/
Apply patches to sync the mac80211 package with changes in the compat-wireless package. These apply clean to SVN revision 28079.
$ cd openwrt/
openwrt$ svn update -r 28079
openwrt$ wget http://o11s.org/files/o11s-openwrt-r28087.diff
openwrt$ patch -p0 < o11s-openwrt-r28087.diff
make V=99
Target binaries are in e.g. bin/ar71xx/
You want the squashfs version.
Refer to OpenWrt wiki for specific install instructions via tftp or bootloader when loading a bare system. If the system already has OpenWrt on it, then you can SCP/wget the sysupgrade image into /tmp then:
sysupgrade openwrt-ar71xx-generic-ubnt-rs-squashfs-sysupgrade.bin
A package for this has been submitted to OpenWrt, but is not included in OpenWrt SVN at time of writing.
See https://lists.openwrt.org/pipermail/openwrt-devel/2011-August/012021.html

OpenWrt needs further work to integrate o11s in its user interface and to correctly configure the interface. In particular, the ath9k needs hardware encryption turned off, and the system may configure the radio in a way where it does not work at all. Therefore, the following command sequence is suggested (put in your own values):
rmmod ath9k
insmod /lib/modules/2.6.39.4/ath9k.ko nohwcrypt=1
iw dev wlan0 interface add mesh0 type mp
iw dev mesh0 set channel 6
ifconfig mesh0 192.168.33.99
iw dev mesh0 mesh join openwrt-mesh
