Unittest fix was not included in the patch that was sent. I will send the
patch again later.
RFC2402 says:
>
> All IPv6 extension headers, as per RFC 1883, encode the "Hdr Ext Len"
> field by first
> subtracting 1 (64-bit word) from the header length (measured in 64-bit
> words).
> AH is an IPv6 extension header. However, since its length is measured
> in 32-bit words,
> the "Payload Length" is calculated by subtracting 2 (32 bit words).
>
> This patch fixes as follows:
>
> return (int(size) - 1) * 8 ->
> return (int(size) + 2) * 4
