libpfring: add new package

PF_RING is a high speed packet capture library that turns a commodity PC into an efficient and cheap
network measurement box suitable for both packet and active traffic analysis and manipulation.
Moreover, PF_RING opens totally new markets as it enables the creation of efficient application such as
traffic balancers or packet filters in a matter of lines of codes.
