    Limit exposure of network device types to the guest.

    Previously, the 'type' of the hypervisor network device, was exposed to
    the guest directly. That does not make sense, as
    a.) this leaks needless information into the guest
    b.) the guest cannot be reasonably expected to make decisions
        based on a type of link that is present underneath the
        virtual device that is presented to the guest.
    c.) guests then are forced to either continuously track these types
        or to assume that unknown type is "phy".

    This limits the exposure of types to a specific list. Any other
    type will be shown to the guest as 'phy'.
