Here is a little series that makes it possible to display and clear
testpmd fwd engines while they run without having to stop them.
This is mostly handy when running stress tests and you look for packets
drops without having to stop/start testpmd forwarding.

Example:

testpmd> show fwd stats all 

  ------- Forward Stats for RX Port= 0/Queue= 0 -> TX Port= 1/Queue= 0 -------
  RX-packets: 261977064      TX-packets: 261977064      TX-dropped: 0             

  ------- Forward Stats for RX Port= 1/Queue= 0 -> TX Port= 0/Queue= 0 -------
  RX-packets: 261985142      TX-packets: 261985142      TX-dropped: 0             

  ---------------------- Forward statistics for port 0  ----------------------
  RX-packets: 261977096      RX-dropped: 0             RX-total: 261977096
  TX-packets: 261985155      TX-dropped: 0             TX-total: 261985155
  ----------------------------------------------------------------------------

  ---------------------- Forward statistics for port 1  ----------------------
  RX-packets: 261985188      RX-dropped: 0             RX-total: 261985188
  TX-packets: 261977128      TX-dropped: 0             TX-total: 261977128
  ----------------------------------------------------------------------------
