Comment:

 Ashish,

 We are testing the new commands to store non-volatile configuration.  All
 seems to work as expected except setting the Mesh Information Element.

 To reproduce:

 0. Get an active antenna and build a kernel from here
 [http://git.infradead.org/users/dwmw2/olpc-stable-mcast.git]

 1. Confirm firmware and boot2 versions:

 {{{
 # lsusb -v | grep 31
   bcdDevice           31.1b
 # ethtool -i msh0
 firmware-version: 5.126.0.p5
 }}}

 2. Change mesh_id

 {{{
 # echo foobar > /sys/class/net/msh0/mesh_ie/mesh_id
 <removed dongle, reinsert>
 # cat /sys/class/net/msh0/mesh_ie/mesh_id
 foobar
 }}}

 3. Boot into standalone mode (e.g. apply 5V via USB) and sniff.  The new
 mesh ID should appear in the beacon and it does not:

 I'm attaching to this ticket the debug logs obtained with
 libertas_debug=0x206000 which show the commands being sent to the wireless
 module.  It all looks correct to me.
