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-serer`` 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.
