Siddharth Vadapalli May 18, 2024, 12:42 p.m. UTC 
Add functions "register_mac()" and "deregister_mac()" to register and
deregister MAC Address of the network interface corresponding to the
Virtual Port with EthFw. Registering the MAC Address with EthFw is
necessary to receive unicast traffic directed to the MAC Address.
