Ethernet addresses are supposed to be assigned to MACs. It's not a good idea to have a MAC appear at different addresses. This is why it always assigns the same address. > .....

Manufacturers are supposed to supply Ethernet addresses for every MAC they support. The "right" way is to have multiple, known unique addresses assigned to boards that have multiple MACs. Other boards may (should) require different assignment methods. -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
