====================
mlx5-updates-2019-09-05

1) Allover mlx5 cleanups

2) Added port congestion counters to ethtool stats:

Add 3 counters per priority to ethtool using PPCNT:
  2.1) rx_prio[p]_buf_discard - the number of packets discarded by device
       due to lack of per host receive buffers
  2.2) rx_prio[p]_cong_discard - the number of packets discarded by device
       due to per host congestion
  2.3) rx_prio[p]_marked - the number of packets ECN marked by device due
       to per host congestion
