net/mlx5e: Add vnic devlink health reporter to representors
Create a new devlink health reporter for representor interface, which reports the values of representor vnic diagnostic counters when diagnosed. This patch will allow admins to monitor VF diagnostic counters through the representor-interface vnic reporter. Example of usage: $ devlink health diagnose pci/0000:08:00.0/65537 reporter vnic vNIC env counters: total_error_queues: 0 send_queue_priority_update_flow: 0 comp_eq_overrun: 0 async_eq_overrun: 0 cq_overrun: 0 invalid_command: 0 quota_exceeded_command: 0 nic_receive_steering_discard: 0 Signed-off-by: Maher Sanalla <msanalla@nvidia.com> Reviewed-by: Moshe Shemesh <moshe@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
