SIOCSIFFLAGS: Name not unique on network

[Chanthearith HUON <chanthearith.huon@telecom-sudparis.eu>]

Hello everyone,

I would like to build a small mesh network based on 802.11s using 
open80211s for performance testing.
After reading linuxwireless.org <http://linuxwireless.org>, I came up 
with "iw" command to create new virtual interface and MP.

Here is my wireless card
"Intel PRO/Wireless 3845ABG"

Its installed driver
"iwl3945"

This wireless card is not listed 
in http://linuxwireless.org/en/users/Devices 
<http://linuxwireless.org/en/users/Devices>
but the driver is in the 
list http://linuxwireless.org/en/developers/Documentation/mac80211#mac80211drivers 
<http://linuxwireless.org/en/developers/Documentation/mac80211#mac80211drivers>

The OS is ubuntu Intrepid Ibex 8.10 with kernel 2.6.27-9-generic

After creating new interface for mesh "iw dev wlan0 interface add mesh 
type mp mesh_id 100". I turned the mesh interface up by "ifconfig mesh up".
I got following error message
" SIOCSIFFLAGS: Name not unique on network "

I got the same error message for " ifconfig mesh 192.168.1.1 "

I search on the net but not much help.

Thank very much,
Thierry
