[ovs-dev] [v4 07/12] test/sytem-dpdk: Add unit test for mfex autovalidator

Kumar Amber kumar.amber at intel.com
Thu Jun 17 16:27:49 UTC 2021


Tests:
  6: OVS-DPDK - MFEX Autovalidator
  7: OVS-DPDK - MFEX Autovalidator Fuzzy

Added a new directory to store the PCAP file used
in the tests and a script to generate the fuzzy traffic
type pcap to be used in fuzzy unit test.
