This value is meaningful only when the local
BCP entity has negotiated the MAC-Address
configuration option, which means the value
of bcpConfigMacAddressControl is enabled(1).
If it is non-zero format, the local BCP get
its MAC address announced. It is represented
in IEEE 802.1 Canonical format.
If it is in zero format, i.e. 00-00-00-00-00-00
then the implementation of the system wishes to
have a MAC address assigned.
