Yeah, thought as much. Is there a document on how Lua dissection works in
general?

In C you cannot rely on the "right" order of dissecting packets, as
dissectors are called multiple times and not necessarily in-order.

Or does Lua work more closely to the tap-interface, where you can rely that
the order is always "right"
