define Package/libpfring/description
  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.
