Adding state to ipfw is fine, but will not be quick and easy I suspect.

Until that is fixed, can we either default to tolerate_missing_ts=1, or just
silently accept rather than drop zero data (!) packets that are missing TS
(yes, gently violating RFC7323)? Either option should restore the behaviour
before D27148.

Again, just for the time being until ipfw is fixed.
