        <td>(BoolOpt) Enable suppression of ARP responses that don't match an IP address that belongs to the port from which they originate. Note: This prevents the VMs attached to this agent from spoofing, it doesn't protect them from other devices which have the capability to spoof (e.g. bare metal or VMs attached to agents without this flag set to True). Spoofing rules will not be added to any ports that have port security disabled. For LinuxBridge, this requires ebtables. For OVS, it requires a version that supports matching ARP headers.</td>
