It is true most vendors of Ethernet cards have burned in MAC Addresses 
and most Ethernet drivers allow for a Locally Administered Address 
(LAA)(over ride).

The CS8900a has no facility to remember a MAC address, it has to be 
programmed by something each time it is powered on. In the modules 16 
bit mode an external serial prom is supported to hold a MAC address but 
that is not an option for us 8-bit folks.

Oliver set the MAC address in Contiki as that was the first app to use 
the Uthernet card. When Ewen and I worked on the Marinetti Link Layer 
for the Uthernet card, we opt'd to keep it the same.

As long as it is unique on your LAN it should not pose a problem ... in 
your case knowing what you should put in the MAC inclusion list on your 
router is important. Others have provided ways of determining the MAC 
address of any LAN device, if you don't have access to that info from 
the vendor. Turning off your MAC filter momentarily and issuing a DHCP 
request would have been my suggestion.

Hope this helps....
