  net/mlx5e: Update NIC HW stats on demand only (2018-06-28 14:44:38 -0700)

----------------------------------------------------------------
mlx5e-updates-2018-06-28

mlx5e netdevice driver updates:

- Boris Pismenny added the support for UDP GSO in the first two patches.
  Impressive performance numbers are included in the commit message,
  @Line rate with ~half of the cpu utilization compared to non offload
  or no GSO at all.

- From Tariq Toukan:
  - Convert large order kzalloc allocations to kvzalloc.
  - Added performance diagnostic statistics to several places in data path.

>From Saeed and Eran,
  - Update NIC HW stats on demand only, this is to eliminate the background
    thread needed to update some HW statistics in the driver cache in
    order to report error and drop counters from HW in ndo_get_stats.
