Create a lagg failover interface to switch between ethernet and wifi


Configure the wireless device as a secondary which is only used when the Ethernet connection is not available.

With lagg(4), it is possible to configure a failover which prefers the Ethernet connection, while maintaining the ability to transfer data over the wireless connection.

This is achieved by overriding the Ethernet interface’s MAC address with that of the wireless interface.
