Was it removed for any reason ? I went through netdev archives and found some threads relating to this, but no comments were there on why this feature is absent or removed. Could it be to avoid a flood arp attack ? If so, any reason why it cannot be implemented under a configuration param ? I would appreciate if someone can throw any light on this. Thanks, - KK
