Automatic network card configuration?

If you want a generic netplan config then you can try something like the following. It will match all physical wired network cards and use DHCP to configure them.

network:
    version: 2
    ethernets:
        zz-all-en:
            match:
                name: "en*"
            dhcp4: true
        zz-all-eth:
            match:
                name: "eth*"
            dhcp4: true

I am copying this configuration directly from the current server installer configuration.
