Version-Release number of selected component (if applicable): openstack-neutron-11.0.0-0.20170503012423.617fc60.el7ost.noarch


How reproducible: 100%


Steps to Reproduce:
1. Clone neutron and checkout OSP 12 branch
2. Prepare host for functional tests (tools/configure_for_func_testing.sh)
3. Run functional tests

Actual results: pecan_wsgi.test_controllers tests are failing


Expected results: All tests passed successfully
