     * a "org.freedesktop.NetworkManager.VPN.Connection" (with high priority), we create

     * one or the other type.

     *

     * Another exception is "org.freedesktop.NetworkManager.Device.Veth". It is a NMDeviceVeth

     * and the parent is NMDeviceEthernet. Therefore it contains "org.freedesktop.NetworkManager.Device.Wired"
