Suport different network ifaces #567

Description

During H11 at EHW (legendary Water-Wickj/lavadora villa) unluckily had the same range of IP as the boards 192.168.1.0 which lead to a lot of trouble during testing.

To solve the issues with just a single board we executed (changing board IP & iface)

sudo ip route add 192.168.1.7/32 dev enp0s31f6 

that creates a ip network with only that board.

However, while working with more than one board using RPI set up. Router's IP is identical to RPI's so backend cannot fetch ADJ.

Posible solution,
Select network iface menu, modify backend to handle this.
