Comment 4 for bug 1561695

This bug might merrit a little bit more than "low" priority. The only reason I say that is I had to nuke my OVS database to clear out those interfaces and this was an issue that happened out of the blue for me. Slowly my node became less and less responsive due to the number of interfaces. Clearing them out one by one was going at a rate of about 1 every 3 seconds, database reset and rekick of neutron services was the faster option.
