## To save the api message table decode tables, configure a filename. Results in /tmp/<filename>

  ## Automatic pinning of thread(s) to CPU core(s)

  ## Sets number of CPU core(s) to be skipped (1 ... N-1)
  ## Skipped CPU core(s) are not used for pinning main thread and working thread(s).
  ## The main thread is automatically pinned to the first available CPU core and worker(s)
  ## are pinned to next free CPU core(s) after core assigned to main thread

  ## Workers are pinned to N consecutive CPU cores while skipping "skip-cores" CPU core(s)

  ## Set scheduling policy and priority of main and worker threads

  ## Scheduling policy options are: other (SCHED_OTHER), batch (SCHED_BATCH)
  ## idle (SCHED_IDLE), fifo (SCHED_FIFO), rr (SCHED_RR)
  # scheduler-policy fifo

  ## Scheduling priority is used only for "real-time policies (fifo and rr),

  ## Disable multi-segment buffers, improves performance but
  ## disables Jumbo MTU support
  # no-multi-seg

  ## Change hugepages allocation per-socket, needed only if there is need for
  ## larger number of mbufs. Default is 256M on each detected CPU socket
