New Revision: 347805
URL: https://svnweb.freebsd.org/changeset/base/347805

Log:
  MFC r347255:
  Fix tx_jumbo_packets counter in mlx5en(4).
  
  Instead of reading Ethernet RFC 2819 pXtoYoctets counters from
  hardware which counts RX octets, count tx_stat_pXtoYoctets from
  Ethernet extended counters which counts TX octets.
  
  TX jumbo counters should be accumulated only after the PPCNT
  counters were fetched from hardware with their latest value.
