Public bug reported:

Update of segmentation ID for vlan networks was introduced by RFE:
https://bugs.launchpad.net/neutron/+bug/1806052

When I'm trying to update segmentation_id of network now, I got internal
server error return.

Steps to reproduce:

1. Create vlan network like:

[00:35:45] vagrant@devstack-centos-ovs:/opt/stack/tempest$ neutron net-show test-vlan
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

2. Try to update segmentation_id like:

[00:38:50] vagrant@devstack-centos-ovs:/opt/stack/tempest$ neutron net-update test-vlan --provider:segmentation_id 2000
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
Request Failed: internal server error while processing your request.
Neutron server returns request_ids: ['req-2b8ebe5e-791a-497b-a5ec-24a3d6071f7d']


3. In neutron server logs I see error like:

  2. Try to update segmentation_id like:

  [00:38:50] vagrant@devstack-centos-ovs:/opt/stack/tempest$ neutron net-update test-vlan --provider:segmentation_id 2000
  neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
  Request Failed: internal server error while processing your request.
  Neutron server returns request_ids: ['req-2b8ebe5e-791a-497b-a5ec-24a3d6071f7d']

  
  3. In neutron server logs I see error like:
