How are the MAC addresses assigned? So if I order ten Ethernet chips from Digikey will they come with something from the manufacturer indicating which MAC addresses to use? Or do I need to register as a vendor and get my own block of addresses?
If you are designing your own board in relatively low quantities, you might want to look at Maxim chip DS2502-E48. It holds a guaranteed unique Ethernet MAC address, and would save you the hassle and cost of registering to get your own address block. The chip uses the Dallas/Maxim 1-wire interface which I don't think u-boot supports (at least, not at the time), so I wrote a u-boot standalone bit-bang program to print the MAC address, and I manually set ethaddr in the u-boot environment.
