You have already posted this very same message to
linux-net@vger.kernel.org
and:
netdev@oss.sgi.com
lists. If you don't get reply from those (netdev mainly), the
linux-kernel is not going to yield cheers either.

People that know the networking code intimately are presently
"somewhat" busy, Be patient, repeat this topic at netdev
list after about a week.

TCP Timestamps ?
(Which Linux does use if the other end supports them too.)

Of course, what is "rate" ? Units of something per units
of time ? Packets ? Payload bytes ? How does the size
of payload data in the packets affect the "rate" ?
