Adding a rule dynamically to the ARP responder is only possible if we can forward the GARP packet to the openflow controller where the openflow controller can process the IN_PACKETS and then make a decision on creating a flow in the ARP responder table.
Is this possible in neutron openflow native drivers today. Any l2 openflow experts can comment on it.
This would be the simplest approach otherwise, we need to forward it to the user space where we process the packet and then send it to Neutron server to take necessary action.
