Viacheslav Ovsiienko 3b025c0ca4 net/mlx5: provide send scheduling error statistics
The mlx5 PMD exposes the following new introduced
extended statistics counter to report the errors
of packet send scheduling on timestamps:

  - txpp_err_miss_int - rearm queue interrupt was not handled
    was not handled in time and service routine might miss
    the completions

  - txpp_err_rearm_queue - reports errors in rearm queue
  - txpp_err_clock_queue - reports errors in clock queue

  - txpp_err_ts_past - timestamps in the packet being sent
    were found in the past, timestamps were ignored

  - txpp_err_ts_future - timestamps in the packet being sent
    were found in the too distant future (beyond HW/clock queue
    capabilities to schedule, typically it is about 16M of
    tx_pp devarg periods)

  - txpp_jitter - estimated jitter in device clocks between
    8K completions of Clock Queue.

  - txpp_wander - estimated wander in device clocks between
    16M completions of Clock Queue.

  - txpp_sync_lost - error flag, the Clock Queue completions
    synchronization is lost, accurate packet scheduling can
    not be handled, timestamps are being ignored, the restart
    of all ports using scheduling must be performed.
