when vpp recevie a data packet,and hadn't learn arp of the dest ip, vpp will send a arp request. If vpp recevie 1000 packets to the same dest ip, vpp will send 1000 arp request. It may cause arp broadcast storm or waste network bandwidth My question is: is there a state machine of arp in vpp? when the arp state is in request. the protocol stack should not send arp packets. I think it's a normal behavior of protocal stack.
