net/mlx4_en: Moderate ethtool callback to show more statistics

Browse Source 
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.
