[Soekris] Ethernet L2 Address (arp) problem

[Chris]

If it`s true, that the interfaces have separate eeproms,
i must going to retry the story in order to see, if always
occurs. 
The net4501 was connected trough only one ethernet cable to 
the switch, server and sniffing computer.
Ethernet port two and tree was definitly down. (not connected).
On the serial console, 3 pci devices are reported and 
the mac address are displayed to perform the
PXE dhcp request.

No cable or other hardware changes was made.
The board are reset trough the reset jumper (J4 or so, i dont 
remember the right switch).
