debugging 802.11s

[Andrey Yurovsky]

Hi Keir.  With NetworkManager not running, can you try things again
from the top?

1) reload the driver
# modprobe -r ath5k
# modprobe ath5k

2) bring up your mesh interfaces, ex:
# iw dev wlan0 interface add mesh0 type mp mesh_id mymesh
# ifconfig mesh0 up
# ifconfig mesh0 10.0.0.1
(etc)

...and then ping again?
# ping -c 2 -I mesh0 10.0.0.2

Also, what's the git tag for your kernel (see Luis' instructions on
how to obtain this via git-describe).  Thanks,

  -Andrey
