1 This is the readme for the Das U-Boot standalone program smc91111

10 1. Ensuring U-Boot's MAC address can be set in hardware
17 1. Ensuring U-Boot's MAC address can be set in hardware
18 --------------------------------------------------------------------------
20 On the Internet - MAC addresses are very important. Short for Media
22 each node of a network. When things are not unique - bad things
23 can happen.  This is why U-Boot makes it difficult to change MAC
