net/mlx5e: Add HW_GRO statistics
This patch adds HW_GRO counters to RX packets statistics:
- gro_match_packets: counter of received packets with set match flag.
- gro_packets: counter of received packets over the HW_GRO feature,
this counter is increased by one for every received
HW_GRO cqe.
- gro_bytes: counter of received bytes over the HW_GRO feature,
this counter is increased by the received bytes for every
received HW_GRO cqe.
- gro_skbs: counter of built HW_GRO skbs,
increased by one when we flush HW_GRO skb
(when we call a napi_gro_receive with hw_gro skb).
- gro_large_hds: counter of received packets with large headers size,
in case the packet needs new SKB, the driver will allocate
new one and will not use the headers entry to build it.
