This project implements an IP TTL filter in hardware. If an IPV4 
packet is identified, the DUT checks its TTL field. Based on previous values of TTL in former packets, 
the machine decides if the packet is spoofed or not. The main page 
of this

This page shows a simple test with multiple frames. Some are UDP and some are ARP. The wave shows that the ARP packets 
are ignored (drop count increment). For each packet, identified as IPV4, learning and the check for spoof is 
exercised.
