|jd$��i�dS)'a�This method parse a cloudinit.net.network_state dictionary (config) and
       maps netstate keys/values into a dictionary (entry) to represent
       netplan yaml.

    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}
