Re: [PATCH] make _minimum_ TCP retransmission timeout configurable take 2

Enable configuration of the minimum TCP Retransmission Timeout via
a new sysctl "tcp_rto_min" to help those who's networks (eg cellular)
have quite variable RTTs avoid spurrious RTOs.

Thanks for doing this work Rick.

But as John Heffner and I both mentioned, it's pretty clear we should
do this as a routing metric.  Both for handling realistic scenerios
where the sysctl doesn't work, and to help prevent misuse (example:
someone decides that it would be _totally_ _awesome_ for "Carrier
Grade Linux" to set this to 3 seconds by default in /etc/sysctl.conf
and crap like that).
