Currently, neutron tunnel endpoints must be IPv4 addresses, i.e. $HOST_IP, although IPv6 endpoints are supported by most drivers. Create a TUNNEL_IP_VERSION variable to choose which host IP to use, either HOST_IP or HOST_IPV6, and configure it in the OVS and Linuxbridge agent driver files. The default is still IPv4, but it can be over-ridden by specifying TUNNEL_ENDPOINT_IP accordingly. This behaves similar to the SERVICE_IP_VERSION option, which can either be set to 4 or 6, but not 4+6 - the tunnel overhead should be consistent on all systems in order not to have MTU issues. Must set the ML2 overlay_ip_version config option to match else agent tunnel sync RPC will not work. Must set the OVN external_ids:ovn-encap-ip config option to the correct address. Updated 'devstack-ipv6-only' job definition and verification role that will set all services and tunnels to use IPv6 addresses.

Neutron plugin specific files
Neutron plugins require plugin specific behavior.
The files under the directory, lib/neutron_plugins/, will be used
when their service is enabled.
Each plugin has lib/neutron_plugins/$Q_PLUGIN and define the following
functions.
Plugin specific configuration variables should be in this file.
- filename:
$Q_PLUGIN- The corresponding file name MUST be the same to plugin name
$Q_PLUGIN. Plugin specific configuration variables should be in this file.
- The corresponding file name MUST be the same to plugin name
functions
lib/neutron-legacy calls the following functions when the $Q_PLUGIN is enabled
neutron_plugin_create_nova_conf: optionally set options in nova_confneutron_plugin_install_agent_packages: install packages that is specific to plugin agent e.g. install_package bridge-utilsneutron_plugin_configure_common: set plugin-specific variables,Q_PLUGIN_CONF_PATH,Q_PLUGIN_CONF_FILENAME,Q_PLUGIN_CLASSneutron_plugin_configure_dhcp_agentneutron_plugin_configure_l3_agentneutron_plugin_configure_plugin_agentneutron_plugin_configure_serviceneutron_plugin_setup_interface_driverhas_neutron_plugin_security_group: return 0 if the plugin support neutron security group otherwise return 1neutron_plugin_check_adv_test_requirements: return 0 if requirements are satisfied otherwise return 1
