Bug Description

It happens from time to time that some functional test is failing due to timeout during creation of the interface in a bridge.
Example of such failure: https://storage.bhs.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_c2e/767922/9/gate/neutron-functional-with-uwsgi/c2e764b/testr_results.html
