Hi

I am trying to get network manager working on a embedded Linux platform. 
The setup has a custom SOC with network controller on board. 
Vendor has provided us BSP that contains Linux kernel with network driver built into it.

Kernel version is 2.6.22.19 and its running busy box.

When I try to run NetworkManager it gives out following output:
 
$ ./NetworkManager --no-daemon --config=/etc/NetworkManager/nm-system-settings.conf 
NetworkManager[909]: <info> NetworkManager (version 0.8.1) is starting...

As we can see in log it has started but ignored both the network interfaces saying :

NetworkManager[909]: <warn> /sys/devices/virtual/net/eth1: couldn't determine device driver; ignoring...


I found a thread with the same issue(http://mail.gnome.org/archives/networkmanager-list/2010-July/msg00015.html), but it doesn't have any pointers to solution.

Here is my output of ls -la /sys/class/net
