Re: [PATCH] tcp: Implement a two-level initial RTO as per draft RFC 2988bis-02.

Prior to this patch, Linux would always use 3 seconds (compile-time
constant) as the initial RTO.  Draft RFC 2988bis-02 proposes to tune
this down to 1 second and, in case of a timeout during the TCP 3WHS,
revert the RTO back up to 3 seconds when data transmission begins.

We just had a discussion where it was determined that changes to
these settings are "network specific" and therefore that if it
is appropriate at all (I'm still not convinced) it is only suitable
as a routing metric.
