When the rdisc6 utility is available probe for router advertisement. configure eni and rhel-netscripts interfaces to do IPv6 address configuration according to the flags in the RA recived from the router. The systemd service file timeout is DIB_DHCP_TIMEOUT * 2, so that DHCPv4 can timout, and dhcpv6 run before the service times out. Retries are commented in dhclient.conf, without it we end up trying DIB_DHCP_TIMEOUT * 60 before the client move on to IPv6. WHEN: Stateful address conf. : No Stateful other conf. : No THEN: Do not run dhclient at all, autoconfiguration via SLAAC only. WHEN: Stateful address conf. : No Stateful other conf. : Yes THEN: Run "dhclient -6 -S", The ``-S`` option makes the dhcp client not request an address, only other options such as DNS servers and NTP servers from DHCPv6 server. WHEN: Stateful address conf. : Yes Stateful other conf. : Yes THEN: The dhcp client should request an address _and_ other options such as DNS servers and NTP servers from DHCPv6 server. NOTE: No IPv6 support added for suse-netscripts Closes-Bug: 1754219 Change-Id: Icdc79875c33f894ab7eaec8afdfb33a731efff99
