Public bug reported: When DHCP agent tries to set fixed_ips parameter for DHCP port (see https://bugs.launchpad.net/networking-calico/+bug/1541490) Neutron checks ipv6_address_mode and ipv6_ra_mode options of subnet that corresponds to the given fixed IP even for IPv4 subnet. And this fails as IPv4 subnet does not have such options (see traceback http://paste.openstack.org/show/580996/). And, of course, you cannot set such flags for IPv4 subnet. I'd expect that such check is performed for IPv6 subnets only.
Probably, this situation is possible not only while using non-native DHCP agent. Neutron version: Newton (7f6b5b5d8953159740f74b0a4a5280527f6baa69).
