Improve catch-all network interface deviceSelector.

What? (description)

Change example for catch-all network interface deviceSelector.

Why? (reasoning)

The existing example does not work on Raspberry Pi, I assume since the network interface is not a PCIe device but connected to the USB controller.

I am using Raspberry Pis (Hardware PHY) and Proxmox VMs (VirtIO PHY). The common attributes of the ethernet interfaces seem to be type: ether and kind: ''.

Acceptance

Please use the following checklist:

• you linked an issue (if applicable)
• you included tests (if applicable)
• you ran conformance (make conformance)
• you formatted your code (make fmt)
• you linted your code (make lint)
• you generated documentation (make docs)
• you ran unit-tests (make unit-tests)

See make help for a description of the available targets.

Nevermind, it seems these fields are not supported in the deviceSelector config.

What is the recommended way to match the network interface on Raspberry Pis? It seems the only options are to match the driver (bcmgenet) or by a specific hardwareAddr, but then this won't match on the Proxmox VMs.

Are you looking for a deviceSelector that would match across different hardware types? I guess this might be tricky, but still might be a nice feature request. We could add a match for physical interfaces (that's what you described with type: ether and kind: )

For my simple setup with only a single hardware interface per device, ideally I would not have to specify any selector and Talos should just use the only available interface.

you can also use net.ifnames=0 and have eth0 if you have a single interface, but the request for a simple device selector makes sense

#8173 implements physical: true device selector.
