  mlx5: Add software tx_jumbo_packets counter
  
  This counter will represent transmitted packets which has more than
  1518 octets.
  The NIC has multiple hardware counters for counting transmitted
  packets larger than 1518 octets. Each counter counts the packets
  in specific range.
  We accumulate those counters to have a single counter.
