[PATCH net-next 2/5] net/mlx5e: Report hw_gro_packets and hw_gro_bytes netdev stats

[Tariq Toukan <tariqt@nvidia.com>]

From: Gal Pressman <gal@nvidia.com>

Report RX hardware GRO statistics via the netdev queue stats API by
mapping the existing gro_packets and gro_bytes counters to the
hw_gro_packets and hw_gro_bytes fields.
