> 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.
