https://bugs.launchpad.net/neutron/+bug/1468236 has some discussion about
this.  Please note, though, that that discussion is 8 months old, and many
of the details discussed there may now have changed; in particular I think
the scalability of the reference Neutron DHCP agent may have improved since
then.
