- have ethernet connection as unmanaged.
- create (or have) a suitable profile for the connection.- make the device as managed. No default wired connection gets created.
- delete the profile.
Note that NMManager does in manager_device_state_changed():
»···if (NM_IN_SET (new_state, »··· NM_DEVICE_STATE_UNAVAILABLE, »··· NM_DEVICE_STATE_DISCONNECTED)) »···»···nm_settings_device_added (priv->settings, device);
that means, when the device the next time goes through UNAVAILABLE/DISCONNECTED states, we will suddenly create the default "Wired connection 1" profile.
That doesn't seem right. When a device is suitable to have a default-wired connection, we should only check once whether to create it. We should not retry that later. The !no-auto-default mechanism exists so we can start NetworkManager without a profile for the device. It doesn't mean that we later one (after previously deciding not to create a profile), we still create it.
