    hyperv/hn: Fix UDP checksum offload issue in Azure.

    UDP checksum offload does not work in Azure if following conditions are
    met:
    - sizeof(IP hdr + UDP hdr + payload) > 1420.
    - IP_DF is not set in IP hdr

    Use software checksum for UDP datagrams falling into this category.

    Add two tunables to disable UDP/IPv4 and UDP/IPv6 checksum offload, in
    case something unexpected happened.
