voidnfq_tcp_compute_checksum_ipv4(structtcphdr*tcph,structiphdr*iph)
       nfq_tcp_compute_checksum_ipv4 - computes IPv4/TCP packet checksum

       Parameterstcph pointer to the TCP header
           iph pointer to the IPv4 header

       Notenfq_tcp_mangle_ipv4() invokes this function. As long as developers always use nfq_tcp_mangle_ipv4
           when changing the content of a TCP message, there is no need to call nfq_tcp_compute_checksum_ipv4.

   voidnfq_tcp_compute_checksum_ipv6(structtcphdr*tcph,structip6_hdr*ip6h)
       nfq_tcp_compute_checksum_ipv6 - computes IPv6/TCP packet checksum

       Parameterstcph pointer to the TCP header
           ip6h pointer to the IPv6 header

       Notenfq_tcp_mangle_ipv6() invokes this function. As long as developers always use nfq_tcp_mangle_ipv6
           when changing the content of a TCP message, there is no need to call nfq_tcp_compute_checksum_ipv6.
