(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}  cSs2| st|t r|S||kr(|j|S|gSdS)zT Helper to convert strings to list of strings, handle single string N)
