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}
