summary: Ensure network interface works.
details: |
The network interface allows a snap to access the network as a client.
A snap which defines the network plug must be shown in the interfaces list.
The plug must be auto-connected on install and, as usual, must be able to be
reconnected.
A snap declaring a plug on this interface must be able to access network
services.
