interface: callback to manage extra MAC addresses

Type: feature

New callback vnet_hw_interface_add_del_mac_address().

Add or delete secondary MAC addresses on a hardware interface.
This will allow packets to be processed which have a destination
MAC address other than the primary programmed MAC address without
needing to put the device into promiscuous mode.
