First you should request an OUI (see
http://standards.ieee.org/regauth/oui/index.shtml). It is used as the
left part (3 bytes) of an ethernet MAC address.
Then you have to assign the other 3 bytes and ensure that one MAC
address never is used twice.
To accomplish this you can use the serial number of your device or
special chips that contain such unique numbers.
