ClockIdentity
Represents an IEEE 802 MAC address represented in the `canonical' order defined by IEEE 802.1a, EUI-64. EUI-48 converts to EUI-64 as specified by IEEE. The conversion assigns values 255 and 254 to octets 3 and 4 respectively, where octet 0 is the most significant and octet 7 the least. For example, EUI-48 of AC:DE:48:23:45:67 would extend to AC:DE:48:FF:FE:23:45:67.
