(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} � c S s* | rt | t�s | S || v r| �|�S | gS )zT Helper to convert strings to list of strings, handle single string )� isinstance�str�split)�obj�tokenr r r �_listifyU s �z$_extract_addresses.<locals>._listifyN�subnets�type�dhcp�4T�dhcp6)�static�static6z%s�address�prefixz/%d�gateway�default)�via�toF)�strictzAGateway %s is not contained within subnet %s, adding on-link flagzon-linkzDFailed to check whether gateway %s is contained within subnet %s: %s�dns_nameservers� dns_search�mtuzipv6-mtu�routesz%s/%s�network�metric�d zZNetwork config: ignoring %s device-level mtu:%s because ipv4 subnet-level mtu:%s provided.r � addresses� nameservers�searchz accept-ra)r )�getr �updater � ipaddress� ip_address� ip_network�LOG�debug� ValueError�warning�appendr �lenr �is_true)r r �ifnamer r% r; r7 r< � searchdomainsr& �subnet�sn_type�addr� new_route�subnet_gateway�subnet_network�e�mtukey�route�to_net� entry_mtu�nsr r r �_extract_addresses0 s� % ������ � � � �rX c s< t � fdd�| �� D ��}t|�dkr |�d|i� d S d S )Nc s$ g | ]\}}|� d d�� kr|�qS )z bond-masterN)r> )r �name�cfg�� bond_masterr r � <listcomp>� s �z0_extract_bond_slaves_by_name.<locals>.<listcomp>r � interfaces)�sortedr rH r?
