DestinationAddress is defined according to the destination_mac_address in IEEE 802.1Qcc-2018 clause 46.2.3.4.1, which represents the destination MAC address in the Ethernet header of the streamed data packets. Entry[n] of DestinationAddress is mapped to octet[n] of destination_mac_address.

SourceAddress is defined according to the source_mac_address in IEEE 802.1Qcc-2018 clause 46.2.3.4.1, which represents the source MAC address in the Ethernet header of the streamed data packets. Entry[n] of SourceAddress is mapped to octet[n] of source_mac_address.
