Hi Andrea, My suggestion would be for you to overload the Flow struct with your own. In that new struct, you can override how pull_tcp works and have an additional field that stores the seq number.
Try not to muck with the main distribution, though it is the convenient thing to do (at least in the short term). You will find that you will diverge from the main distribution and need to fix bugs on your own later.
