--- Comment #11 from Richard Scheffenegger <[email protected]> ---
To add more confusion: 

The advisory UTO option could be used by ipfw to piggy-back on some ACKs, to
indicate to the end hosts, within which interval it expects the end hosts to
send out another keepalive or data/control packet.

(Obviously, FBSD would need to implement processing of this options too.
Also, it doesn't help the puristic case, where no modification of the on-wire
packet stream is allowable).

Pragmatically, the most easy way out would be for ipfw to keep additional state
with the TSopt val and ecr of the most recent packet, and include the TSopt in
ipfw-originated keepalives.
