The latest code in CVS uses "net.address" for the UDI.  I'm not sure
that really changes anything though.

Yeah, this is an issue.  It should be getting the interface name from
class_device->name in net_class_pre_process().  Can you use gdb to break
in that function and post the output of "print *class_device" ?

Yeah.  The interface should be set there; I'm not sure why libsysfs
wouldn't set it.

Thanks for your help,
