Seems this target does not get as much attention as for example ar71xx.
Until now there is this nasty mac address bug that every wdr4900 has the
same mac address [1] (if you don't manually set it in /etc/config/network).

Maybe you have one of these new Loco M5 XW? Support for that device has
been added with r42549 (9 days ago) [1] and is only available in current
trunk (unfortunately not in barrier breaker rc3).
