WebThere is no longer a need for the call to etharp_ip_input() from the ingress traffic handling code (the network driver in our case). It also makes the stack more BSD compliant (AFAIK), as most stacks *do not update their ARP cache from IP packets*. So I suggest to remove the call to etharp_ip_input() altogether.
