Documentation       This suite tests IPMI POH Counter Support in OpenBMC.
...                 Feature: IPMI POH Counter Support
...
...                 POH (Power-On Hours) counter is the incremental count of power ON
...                 hours in the system.
...
...                 Request and Response data defined under data/ipmi_raw_cmd_table.py
...
...                 Testcases added -
...                 Get POH Counter Command Via IPMI
...                 Verify Get POH Counter With Invalid Data Request Via IPMI
...                 Verify POH Counter Reading With Wait Time
...                 Verify POH Counter Reading With Host Power Off
...                 Verify POH Counter Reading With Host Power On
...
...                 Script compares Minutes per count and Counter reading for the above scenarios.
...
...                 Minutes per count usually 60 minutes.
...
...                 Wait Time given - 1 hour, 1 hour 30minutes when Host power OFF, 1 hour
...                 after Host Power ON
...
...                 Comparison between Initial POH Counter reading and reading after wait
...                 time / Power operation.
