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. Change-Id: I6beecbcb8932fc1fe45b567f76fa3706feefae2c Signed-off-by: Matthew Smith <mgsmith@netgate.com>
