Incorrect metada in ConfigDrive when using barematal ports under neutron

If baremetal instance is booted with neutron network and config drive enabled, it receives incorrect network data in network_data.json, which cause trace in cloud-init: ValueError: Unknown network_data link type: unbound

All software is at Newton: ironic (1:6.2.1-0ubuntu1), nova (2:14.0.1-0ubuntu1), neutron (2:9.0.0-0ubuntu1).

ironic is configured for multitenancy (to use neutron): default_network_interface=neutron.
neutron is configured for ML2, ML2 is configured for networking_generic_switch. Former works fine and toggle port on real switch in vlan (access) and out.

Network is configured to work with vlans.
