A single flow_cookie field in the flow_mod would not ordinarily be able
to usefully serve both the purpose of matching and updating flow cookies
at the same time. I think that the ability to match on flow cookies was
considered more useful. The possibility of having separate flow_mod
fields for matching and updating flow_cookie wasn't considered, if I
recall correctly.
