Yeah, that's a bad bug in the rule matching. The sysfs_device is NULL,
and we try to find the name here. I will fix it.
But I don't know why the sysfs_device is NULL in this case, I can't
reproduce it with the same hardware. Thomas, it would be nice if you can
send the output of:
udevinfo -a -p /sys/class/net/eth<N>
Thanks,
Kay
