Followup to my followup:

If a RFC1323 box talks to another, on connection setup they will
negotiate to use the enhanced code, and fail, when later the Linux in
between damages the packets in transit. If a RFC1323 box talks to Linux,
they won't negotiate rfc1323 and thus at least use the old pre-1323 tcp
correctly.
