Hi Radu,

You are right: sequence number is not a natively supported primitive
and, since it's part of the header and not of the flow record, it is
not possible to leverage the aggregate_primitives framework either.

This said, writing native support for the sequence number is not a
super big deal; to help my prioritization, can you say how urgent/
important this is for you? Is anybody reading also interested into
this?

Cheers,
Paolo
