Fwd: RFC5798 - clarification on checksum calculation

Hello

I am thinking of submitting an errata for RFC 5798 Sec. 5.2.8 to make
it more precise in describing the checksum calculation for each address family.

But reading a few responses here, I gathered that there is no general
agreement as to the original intention of the text,
I believe that for IPv4, the checksum is calculated without
pseudo-header so that it is backward compatible with RFC 3768.

Any other opinions - particularly from original authors ?

Kind Regards

Re: Fwd: RFC5798 - clarification on checksum calculation

My interpretation of the specification is that for IPv4 checksum is calculated without pseudo-header.

It would be nice if RFC authors can clarify.
