Further verified code in ipam_pluggable_backend.py file and observed
following code at
https://github.com/openstack/neutron/blob/stable/pike/neutron/db/ipam_pluggable_backend.py#L453
# TODO(kevinbenton): remove after bug/1666493 is resolved
if subnet['id'] != ipam_subnet.subnet_manager.neutron_id:
raise RuntimeError(
"Subnet manager doesn't match subnet. %s != %s"
% (subnet['id'], ipam_subnet.subnet_manager.neutron_id))
As ipam_subnet.subnet_manager is defined specific to the neutron
default ipam driver at
https://github.com/openstack/neutron/blob/stable/pike/neutron/ipam/drivers/neutrondb_ipam/driver.py#L129
, it should not be used in generic file such as
ipam_pluggable_backend.py which is used by other ipam_drivers.
