[Bug 1486150] [NEW] Neutron port-update fails to roll back the binding:profile data in ports table in neutron DB if a MechanismDriverError thrown by a mechanism driver
Public bug reported:
Steps to reproduce:
1. Inherit the update_port_precommit(self, context) in the vendor mechanism driver
2. Throw MechanismDriverError in this method based on validation
Expected output:
None of the updated port parameters should be added in DB for the ports table as well as ml2_port_bindings table.
Actual output:
Eventhough the MechanismDriverError thrown by the vendor mechanism driver , ml2 plugin updates the value in the DB.
Attached the logs in paste site:

Neutron port-update REST API output:
Earlier neutron port was created with local_link_information: “port_id”
as Ten-GigabitEthernet1/0/36 using port-create command
