There are a couple of ways that a tenant can setup their subnet to cause the DHCP agent to go into a failure loop when it tries to create a port. This creates extra load on the agent that makes its response to other changes slower.

There are two fixes that should be back-ported to all of the mos-neutron branches.

The first has merged so it's ready to be back-ported: https://review.openstack.org/#/c/177187/

The second is still under review, but should be ready in the next couple of days: https://review.openstack.org/#/c/157697/
