>TFD for "Information Refresh Time Option for DHCPv6" Feature.
>
>BASIC INFORMATION
>=================
>This TFD covers DevTrack ID 201223
>
>Release: RHEL6
>Contact: Sridhar Samudrala <sri@us.ibm.com>
>         Mitsuru Chinen <chinen@jp.ibm.com>
>
>PHASE 1
>=======
>Risk Assessment
>---------------
>  This is a "low" risk feature that only affects users that enable IPv6 in
>their network environment.
>
>Planned Test Methodology
>------------------------
>  Manual tests
>
>PHASE 2
>=======
>Description of Feature
>----------------------
>Update DHCPv6 implementation(Client and Server) to support RFC4242,
>"Information Refresh Time Option for DHCPv6". This feature establishes
>the lifetime for the configuration data without IPv6 address information.
>It is an update of RFC3736 that we already supported. It is necessary to
>keep the appropriate configuration data (e.g. DNS server)
>
>Test Plan
>---------
>Manual Tests:
>1. Prepare 2 Linux boxes. One is a server, the other is client.
>
>2. Prepare dhcp6s.conf on the server.
>    | # cat /root/dhcp6s.conf << EOF
>    | option dns_servers 2001:db8::2;
>    | allow information-refresh-time 600;
>    | interface eth0 {
>    | link AAA {
>    | };
>    | };
>    | EOF
>
>3. Prepare dhcp6c.conf on the client
>    | # cat /root/dhcp6c.conf << EOF
>    | interface eth0 {
>    | information-only;
>    | request domain-name-servers;
>    | };
>    | EOF
>
>4. Start dhcp6s at the server
>    | # dhcp6s -vf -c /root/dhcp6s.conf lan0
>
>5. Start dhcp6c at the client
>    | # dhcp6c -vf -c /root/dhcp6c.conf eth0
>
>*) Step 6 and 9 must be done within 600 seconds.
>6. At the client, check /etc/resolv.conf includes the address of DNS
>   server written in dhcp6s.conf  <== Check 1
>    | # cat /etc/resolv.conf
>    | nameserver 2001:db8::1
>
>7. At the server, stop the dhcp6s.
>
>8. At the server, modify the address of DNS server written in dhcp6s.conf
>   from 2001:db8::1 to 2001:db8::2.
>    | # dhcp6s -vf -c /root/dhcp6s.conf lan0
>
>9. At the server, restart dhcp6s
>
>10. After 600sec is passed from dhcp6c starts, check /etc/resolv.conf includes
>    the new address of DNS server at the client <== Check 2
>    | # cat /etc/resolv.conf
>    | nameserver 2001:db8::2
