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.
