Ethernet backhaul

With firmware 1.2.6 installed, there is not much more to do than to connect the second AX55 to the Mesh Master.
But, when the Mesh Master is configuring the mesh with ethernet backhaul, it creates a loop for about 1 to 2 seconds. This is a problem if there are switches in the network that have loop protection (some devices have STP) enabled. Therefore, it is important to disable loop protection.

Once the secondary mesh node is connected and recognized, it will switch to wired mode and reboot. The Mesh Master node will reboot too.
