net/mlx5: Expose ICM consumption per function
ICM is a portion of the host's memory assigned to a function by the OS
through requests made by the NIC's firmware.
PF ICM consumption can be accessed directly, while VF/SF ICM consumption
can be accessed through their representors in switchdev mode.
The value is exposed to the user in granularity of 4KB through the vnic
health reporter as follows:
$ devlink health diagnose pci/0000:08:00.0 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 icm_consumption: 1032
