Commit Message

David Marchand Jan. 3, 2022, 2:15 p.m. UTC 
The MFEX code and tests do not depend on DPDK anymore.
We can move the unit tests to dpif-netdev.

This test and others in here need a dummy-numa configured.
2 reasons for that:

1. We're asking for 4 CPU cores here (0xC), so the test will not work
   as expected on a smaller system (e.g. GHA).

2. Without dummy-numa real CPU affinity will be applied.  In that
   case during the parallel test execution threads from different tests
   will be scheduled on same cores.  Dummy-numa fakes the CPU affinity
   allowing the kernel to re-schedule pmd threads to different cores
   better utilising system resources.

Best regards, Ilya Maximets.
