I have VM in NAT mode mostly these days, but sometimes I need bridged
network to recognize some hardware on the network, Mikrotik WiFi routers
or printers so I need ability to go to bridge.

If this with NetworkManager-config-server package works, I can at most
times (if I want) plug a LAN to my laptop and be happy. I do not use
LUKS so suspend until I get home 10 minutes later is ok.
