--- deprecations: - The 'segment_mtu' option of the ML2 configuration has been deprecated and replaced with the 'global_physnet_mtu' option in the main Neutron configuration. This option is meant to be used by all plugins for an operator to reference their physical network's MTU, regardless of the backend plugin. Plugins should access this config option via the 'get_deployment_physnet_mtu' method added to neutron.plugins.common.utils to avoid being broken on any potential renames in the future.
