+ In Ubuntu Core, in all supported devices ethernet devices have higher metric than wlan or wwan devices, so packets get routed to the latter always. The metric is 1024, while for instance network-manager assigns these numbers:
  
  ethernet -> 100
  wlan -> 600

  ethernet in all cases when installed.
  
- SRU TEST CASE:
-  * Set up an ethernet and wifi connection using netplan, and check metrics in "ip route". With the current version they have "1024", with the proposed update the ethernet one will have 100, the wifi one 600.

- REGRESSION POTENTIAL: It could in principle happen that someone relies
