Bug Description

I have issued the following command:

neutron net-create public --shared --provider:physical_network public --provider:network_type flat

which produced the following network dictionary passed to Contrail: {'provider:physical_network': u'public', 'updated_at': '2017-08-21T14:22:56Z', 'revision_number': 3, 'port_security_enabled': True, 'provider:network_type': u'flat', 'id': '8897cdac-7f56-4b87-a75b-219119d0d100', 'router:external': False, 'availability_zone_hints': [], 'availability_zones': [], 'ipv4_address_scope': None, 'shared': True, 'project_id': u'3b598c589eb34bceb14ef13c2a263e6c', 'status': 'ACTIVE', 'subnets': [], 'description': '', 'tags': [], 'ipv6_address_scope': None, 'provider:segmentation_id': None, 'name': u'public', 'admin_state_up': True, 'tenant_id': u'3b598c589eb34bceb14ef13c2a263e6c', 'created_at': '2017-08-21T14:22:56Z', 'mtu': 1500, 'vlan_transparent': None}.

Contrail responded with error. Log says:

Field provider:segmentation_id is not required by Neutron and also isn't assigned when network is created. After performing said steps network is available and operable in OpenStack, but Contrail refused to create it on its side. Attempt to provide segmentation-id leads to error:
Invalid input for operation: segmentation_id prohibited for flat provider network.

Need to understand why provider network configuration is used here. Contrail is currently supporting this only for SRIOV and has to change to make it neutron compatible.

Not considering this for R4.1.
