test/sytem-dpdk: Add unit test for mfex autovalidator Tests: 6: OVS-DPDK - MFEX Autovalidator 7: OVS-DPDK - MFEX Autovalidator Fuzzy 8: OVS-DPDK - MFEX Configuration 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.

system-dpdk.at: Fix module not found error for pyhton < 3.6. This fixes the flake8 error on pyhton version older than 3.6 as ModuleNotFoundError in not available before 3.6. ../../tests/mfex_fuzzy.py:5:8: F821 undefined name 'ModuleNotFoundError' Makefile:5826: recipe for target 'flake8-check' failed Since it doesn't really make any sense to catch this exception, try-except block is just removed. Additionally the check for scapy replaced with the more reliable one. Imports re-ordered, because standard imports should go first. Fixes: 50be6715c0 ("test/sytem-dpdk: Add unit test for mfex autovalidator") Signed-off-by: kumar Amber <kumar.amber@intel.com> Signed-off-by: Ilya Maximets <i.maximets@ovn.org>
