$ devlink health dump show pci/0000:82:00.1 reporter fw_fatal
NOTE: This command can run only on PF.
+
+vnic reporter
+-------------
+The vnic reporter implements only the `diagnose` callback.
+It is responsible for querying the vnic diagnostic counters from fw and displaying
+them in realtime.
+
+Description of the vnic counters:
+total_q_under_processor_handle: number of queues in an error state due to
+an async error or errored command.
+send_queue_priority_update_flow: number of QP/SQ priority/SL update
+events.
+cq_overrun: number of times CQ entered an error state due to an
+overflow.
+async_eq_overrun: number of times an EQ mapped to async events was
+overrun.
+comp_eq_overrun: number of times an EQ mapped to completion events was
+overrun.
+quota_exceeded_command: number of commands issued and failed due to quota
+exceeded.
+invalid_command: number of commands issued and failed dues to any reason
+other than quota exceeded.
+nic_receive_steering_discard: number of packets that completed RX flow
+steering but were discarded due to a mismatch in flow table.
+
+User commands examples:
