  OvsPmdCoreList:
    description: >
      A list or range of CPU cores for PMD threads to be pinned to.  Note, NIC
      location to cores on socket, number of hyper-threaded logical cores, and
      desired number of PMD threads can all play a role in configuring this
      setting.  These cores should be on the same socket where
      OvsDpdkSocketMemory is assigned.  If using hyperthreading then specify
      both logical cores that would equal the physical core. Also, specifying
      more than one core will trigger multiple PMD threads to be spawned which
      may improve dataplane performance.
