https://github.com/openstack/neutron/blob/master/neutron/agent/dhcp/agent.py#L332
in neutron.conf:
dhcp_agents_per_network = 1
the bug can be reproduce as below steps:
1. create network1
2. create subnet1(10.0.0.0/24), enable dhcp, then would create a dhcp port such
as 10.0.0.2,
3. delete the dhcp port 10.0.0.2
4. delete the dhcp agent such as DhcpAgent1
5. re-added network1 to the dhcp agent1, then would be a new port 10.0.0.3
6. update the new port from 10.0.0.3 to 10.0.0.2
then there would be an error..
