    Always fill UDP checksums in DHCPv6 replies

    Bug #1244589 re-appeared for IPv6.

    This change adds an ip6tables rule to fix the checksum of DHCPv6
    response packets. Those checksums were left unfilled by virtio (as a
    hypervisor internal optimization), but some picky dhcp clients (AFAIU
    particularly ISC dhclient) try verifying the checksums, so they fail
    to acquire an address if the checksums are left incorrect.
