Extend psample to report the following attributes when available: * Output traffic class as a 16-bit value * Output traffic class occupancy in bytes as a 64-bit value * End-to-end latency of the packet in nanoseconds resolution * Software timestamp in nanoseconds resolution (always available) * Packet's protocol. Needed for packet dissection in user space (always available) Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S.
