The MAC Address of the Network Interface Controller associated with the Remote Insight/ Integrated Lights-Out. This is a 6 octet address in the `canonical` order defined by IEEE 802.1a, i.e., as if it were transmitted least significant bit first, even though 802.5 (in contrast to other 802.x protocols) requires MAC addresses to be transmitted most significant bit first. 16-bit addresses, if needed, are represented by setting their upper 4 octets to all 0`s, i.e., AAFF would be represented as 00000000AAFF.
