The TCP solution (change InitializeChecksum) is interresting and easy to do.

The UDP header is always 8 bytes (i.e. there are no UDP options in header), am
I right ? So no need to change it.

But the best would be to have a unique way for UDP/TCP. With that if others
want to do a new L4 Protocol (such a SCTP), they have a model to follow.

Could you explain a little bit your way to proceed with
Buffer::iterator::GetSize ? I mean in the different classes (*L4Protocol,
*Header).
