Disable IPV6 Autoconf option
Add the option in the GUI to disable ipv6 auto configuration. This is NOT disabling ipv6, this is preventing the network stack from attempting to self-configure (beyond the link-local address).
This is done by adding to /etc/sysconfig/network
IPV6_AUTOCONF=no
but whenever this file gets rewritten by CCE, the manually inserted line is removed.
