-/* Changes for Correlated traffic VNF
-1.      Receive UDP packet
-2.      Modify received packet
-           a.exchange src mac and destination mac
-           b.exchange src ip and destination IP for both IPv4 and IPv6 cases
-           c.exchange UDP src port and UDP destination port
-           d.change the len of the response according to the IMIX definition (
-               option to make traffic more realistic to emulate some IoT payloads)
-3.      send modified packet to the port where it was received.
-
-Such VNF does not need LPM and routing table implementations.
-As the packet modification is very minimal  and there is no memory access as the packet is stored in L3 cache the
-performance of the solution should be sufficient for testing the UDP NAT performance.
