Add the following line to /etc/sysctl.conf
net.ipv4.tcp_ecn = 1
sorry, it should be net.ipv4.tcp_en=0 to disable.
RHL/Fedora reads this file on every startup and adjusts settings
accordingly. If you make changes to /etc/sysctl.conf, you can run
`sysctl -p` to force the system to re-read the file without a reboot.
As root you can run `sysctl -a | less` to read all about the other
settings available through this cool facility (such as for firewalls,
etc.). I prefer this as opposed to echoing to proc, but it may not be
portable to other flavors of Linux. sysctl.conf settings take effect
earlier than they would if placed in rc.local.
