Currently, however, we track the information for each side in independent fields in the structure, meaning we can't easily exploit that symmetry. This makes a number of reorganizations of the tcp splice code so that we can explot that symmetry to reduce code size. This will have some additional advantages when we come to integrate with the in-progress unified flow table. Based on top of the interface identifiers and automatic forwarding cleanup series.
