Log:
  MFC r347279:
  Fix netstat counters mapping in mlx5en(4).
  
  The current mapping of driver counters to netstat counters is wrong.
  For example, a single jabber packet, will cause the Ierrs counter to
  count three times.
  
  The work for mapping the hardware and software counters to their right
  place in netstat counters were already done in Linux, take that as is
  to the FreeBSD driver.
