net/mlx4_en: Use HW counters for rx/tx bytes/packets in PF device
Under SRIOV, the port rx/tx bytes/packets statistics should by read from the HW instead of using the PF netdevice SW accounting. This is needed in order to get the full port statistics and not just the PF own ones Signed-off-by: Eran Ben Elisha <eranbe@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S.
