Logic for generating MAC address:
Mac = B1:B2:B3:B4:B5:B6 (Bx is a byte).

such that the MAC is local and unicast.

Controlled by the global config MACIdentifier

Controlled by the 'mac.identifier' zone-level config

associated with the IP address for which MAC is generated (refer to mac_address
field in user_ip_address table).
