       maps netstate keys/values into a dictionary (entry) to represent
       netplan yaml. (config v1 -> netplan)

    An example config dictionary might look like:

    {'mac_address': '52:54:00:12:34:00',
     'name': 'interface0',
     'subnets': [
        {'address': '192.168.1.2/24',
         'mtu': 1501,
         'type': 'static'},
        {'address': '2001:4800:78ff:1b:be76:4eff:fe06:1000",
         'mtu': 1480,
         'netmask': 64,
         'type': 'static'}],
      'type: physical',
      'accept-ra': 'true'
    }

    An entry dictionary looks like:

    {'set-name': 'interface0',
     'match': {'macaddress': '52:54:00:12:34:00'},
     'mtu': 1501}

    After modification returns

    {'set-name': 'interface0',
     'match': {'macaddress': '52:54:00:12:34:00'},
     'mtu': 1501,
     'address': ['192.168.1.2/24', '2001:4800:78ff:1b:be76:4eff:fe06:1000"],
     'ipv6-mtu': 1480}

�dS)adUse netplan.State._write_yaml_file to write netplan config

    Where netplan python API exists, prefer to use of the private
    _write_yaml_file to ensure proper permissions and file locations
    are chosen by the netplan python bindings in the environment.

    By calling the netplan API, allow netplan versions to change behavior
    related to file permissions and treatment of sensitive configuration
    under the API call to _write_yaml_file.

    In future netplan releases, security-sensitive config may be written to
    separate file or directory paths than world-readable configuration parts.

tjdd|tjd�}|S)aStrip invalid MTU from the netplan config.

    This is a fix for https://github.com/canonical/cloud-init/issues/6239
    A 0 MTU value is NOT valid, but cloud-init accepted it prior to 24.2,
    so rejecting it after c465de8 is a breaking change for existing releases.
