RoCE counters

[ConnectX-4 and above] Added support for exposing error counters on a VPort manager function for all other VPorts. These counters can be used to detect malicious users who are exploiting flows that can slow the device. The counters are exposed through debugfs under: /sys/kernel/debug/mlx5/esw//vnic_diag/

GRO Offload and Zero Copy TCP

Added support for SHAMPO (Split Header And Merge Payload Offload). This is a new functionality that enables stitching of packets data to unified skb representation in the network stack to reduce per-skb overhead.
