Subject: [PATCH net-next 7/7] net/mlx4_en: Moderate ethtool callback to show more statistics
From: Eran Ben Elisha <eranbe@...lanox.com>
More packet statistics are now calculated and visible to the user via
ethtool:
- RX packet errors statistics.
- TX/RX drops are now calculated.
- TX multicast and broadcast statistics.
- RX/TX per priority bytes statistics.
- RX/TX no vlan packets and bytes statistics.
