This application is purposefully built to benchmark the performance
of the Intel DPDK Packet Framework toolbox.

It uses 3 CPU cores connected in a chain through SW rings
(NICs --> Core A --> Core B --> Core C --> NICs)
1. Core A: reads packets from NIC ports and writes them to SW queues;
2. Core B: instantiates a Packet Framework pipeline that uses ring reader
   input ports, a table whose type is selected trhough command line arguments
   (--none, --stub, --lpm, --acl, --hash[-spec]-KEYSZ-TYPE, with KEYSZ as
   8, 16 or 32 bytes and TYPE as ext (Extendible bucket) or lru (LRU))
   and ring writers output ports;
3. Core C: reads packets from SW rings and writes them to NIC ports.
