RHEL: How can I stop TCP from increasing the retransmission delay after each retransmission timeout

Solution In Progress - Updated -

Issue

We have reduced the TCP retransmission time out to 8 ms with the ip command

ip route add 172.16.1.11 via 172.16.1.200 dev eth1 rto_min 8

but have discovered that the second retransmission time out is double that and the third is double that. We need to keep the retransmission time out as short as possible.
