Hi Peter,
What is the reason the MAC address on the AT91 is written in the 2nd address
register, leaving the first one out? Is there something particular about this?
See cpu/arm920t/at91rm9200/ether.c, eth_init()
...
p_mac->EMAC_SA2L = ...
...
The reason I ask is this may confuse OS driver if no MAC address is found in
the first register (which is the case for FreeBSD/ARM, for example).

Sorry Rafal - I don't have access to AT91 boards and/or documentation
Perhaps one of the maintainers can help....
