    hyperv/hn: Workaround erroneous hash type observed on WS2016.

    Background:
    - UDP 4-tuple hash type is unconditionally enabled in Hyper-V on WS2016,
      which is _not_ affected by NDIS_OBJTYPE_RSS_PARAMS.
    - Non-fragment UDP/IPv4 datagrams' hash type is delivered to VM as
      TCP_IPV4.

    Currently this erroneous behavior only applies to WS2016/Windows10.

    Force l3/l4 protocol check, if the RXed packet's hash type is TCP_IPV4,
    and the Hyper-V is running on WS2016/Windows10.  If the RXed packet is
    UDP datagram, adjust mbuf hash type to UDP_IPV4.
