Test dpdk-testpmd performance in IO forward mode

Test dpdk-testpmd performance in IO forward mode

1. Configure flow control

2. Adjust testpmd parameters

3. Create testpmd job to run rxonly on IUT

4. Create testpmd job to run traffic generator on TST

5. Start the jobs

6. If dbells_supp :

   • Attach doorbells filters

7. Start peer and reporting testpmd jobs

8. Retrieve link speed from reporting testpmd

9. Initialize IUT Rx and TST Tx statistics

10. Retrieve Rx stats from running testpmd

11. Retrieve Tx stats from running testpmd

12. Check and log measurement results
