features:
- |
The new ``net-mtu-writable`` extension API definition has been added. The
new extension indicates that the network ``mtu`` attribute is writeable.
Plugins supporting the new extension are expected to also support
``net-mtu``. The first plugin that gets support for the new extension is
``ml2``.
other:

Changing MTU configuration options (``global_physnet_mtu``,
``physical_network_mtus``, and ``path_mtu``) and restarting
``neutron-server`` no longer affects existing networks' MTUs. Nevertheless,
new networks will use new option values for MTU calculation. To reflect
configuration changes for existing networks, one may use the new
``net-mtu-writable`` API extension to update ``mtu`` attribute for those
networks.
