    vtnet: disable hardware TCP LRO by default

    Hardware TCP LRO results in problems in settings with IP forwarding
    being enabled. In case of nodes without IP forwarding, using
    software LRO is also beneficial in general, since it can provide better
    information about what was received on the wire.
    Therefore, disable hardware TCP LRO by default.
    By tuning the loader tunable, this can be changed.
