+Generic filter/flow api
+=======================
+
+Prerequisites
+=============
+
+1. Hardware:
+   Fortville and Niantic
+  
+2. software: 
+   dpdk: http://dpdk.org/git/dpdk
+   scapy: http://www.secdev.org/projects/scapy/
+
+3. bind the pf to dpdk driver:
+   ./usertools/dpdk-devbind.py -b igb_uio 05:00.0
