Hi everybody,

I have isntalled openwrt backfire buildroot from trunk version in TP-link
TL-WR1043ND.
First I followed the steps from http://o11s.org/trac/wiki/OpenWrtBuilding,
but I had building problems with compat-wireless from
http://o11s.org/files/compat-wireless-2.6-o11s-0.4.2.tar.bz2. So I gave up
those steps and made my on 802.11s enabled image following these other
steps:

1- installation:
svn co svn://svn.openwrt.org/openwrt/trunk openwrt
./scripts/feeds update -a
./scripts/feeds install -a
make menuconfig

 - Target System --> Atheros AR71xx/AR7240/AR913x/AR934x
 - Target Profile --> TP-LINK TL-WR1043ND v1
 - Kernel Module --> Wireless Drivers --> <*> kmod-ath9k
 - Network --> Captative Portal --> <*> wifidog
            --> File Transfer --> <*> wget
            --> <*> iperf
            --> <*> tcpdump
            --> <*> traceroute

2- make V=99
3- make kernel_menuconfig

Networking suport --> wireless --> <M> cfg80211 - wireless configuration API
                                             --> <M> Generic IEEE 802.11
Networking Stack (mac80211)
                                                     --> <*> Enable
mac80211 mesh networking (pre-802.11s) support

4- make V=99 (Then the image was generated in bin/ar71xx)

5- I followed the recomended configuration to set up the mesh network:

router 1
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 192.168.2.1/24
iw dev mesh0 mesh join mymesh

router 2
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 192.168.2.2/24
iw dev mesh0 mesh join mymesh

When I run:
iw dev mesh0 station dump

I can see this result:
Station d8:5d:4c:d4:fd:7c (on mesh0)
    inactive time:    920 ms
    rx bytes:    25320
    rx packets:    634
    tx bytes:    223
    tx packets:    3
    tx retries:    0
    tx failed:    0
    signal:      -52 dBm
    signal avg:    -51 [-66, -53, -60] dBm
    tx bitrate:    1.0 MBit/s
    rx bitrate:    1.0 MBit/s
    mesh llid:    65475
    mesh plid:    36832
    mesh plink:    ESTAB

It seems that routers are establishing connection on layer 2, but when I
try to ping they do not respond
I'm using ath9k driver and compat-wireless-2011-11-04.tar.bz2.
Have anyone had similar problem with ath9k + 802.11s in backfire from trunk
version?

Thanks for your attention.

Regards.
