We currently cannot offload to the card if we add extension headers (which incl. fragmentation). Fix two SCTP offload support copy&paste bugs: calculate checksums if fragmenting and no need to flag IPv4 header checksums in the IPv6 forwarding path. Correctly get the payload length in host byte order. While we already plan to support >64k payload here, the IPv6 header payload length obviously is only 16 bit and the calculations need to be right.
