Re: [RFC 1/3] tcp: randomize tcp timestamp offsets for each connection

Here at Google we have been using usec resolution in TCP timestamps for
a while for all our DC traffic, and we have to upstream this at some
point.

It would be nice if the randomization was optional, because having usec
timestamps with a common base (ie no per flow random base) helps a lot
to understand the host delays at transmit time, and receive time.

Would it help to make it per-host instead of per-flow?

I will review your patch more in depth today, thanks.

Great, thanks a lot!
