   5  * This application provides the user the ability to test the
   6  * insertion rate for specific rte_flow rule under stress state ~4M rule/
   7  *
   8  * Then it will also provide packet per second measurement after installing
   9  * all rules, the user may send traffic to test the PPS that match the rules
  10  * after all rules are installed, to check performance or functionality after
  11  * the stress.
  12  *
  13  * The flows insertion will go for all ports first, then it will print the
  14  * results, after that the application will go into forwarding packets mode
  15  * it will start receiving traffic if any and then forwarding it back and
  16  * gives packet per second measurement.
