As the hardware that were affected by this are in use in production, testing this is not something I can just do - I'm afraid.

I want to add that we discovered that this problem is triggered by a combination of running Linux 3.10.0-693.2.2.el7.x86_64 (CentOS 7) and Cisco B200 M2 blades.

I am not sure if it's fair to call this a bug in Neutron, but the workaround in the initial bug report is still valid. We also discovered that similar workaround can be applied in the dhcp-namespaces to fix DNS (which is also broken in the abovementioned setup)
