Hi,

Please, be careful w/ the 'plain ports'.
Rusty has changed the internal structure of the IPv4 parts (acording the skb
linearization) - and these changes are missing from the IPv6 part. In IPv6
every packets are linearized - in IPv4 you have to linearize the required
parts avery time and in some higher-level protocols tha helper functions have
benn changed.
(We have no size parameter in the IPv6 header (like in IPv4) so we cannot seek
in the virtual skb. We have to parse the full header every time. I think that
a plain linearize_all is much more cheaper.)

Regards,
