Our requirement is to add a list of self tests that can summarize if the adapter is functioning properly in a single command during system init. The above tests are the most common ones run by our on-field diagnostics team. Besides, these tests seem to be the most common among other drivers as well. Hence we have added 1. Adapter status test: Tests whether the adapter is alive or crashed 2. Link test: Adapter PHY is up or not. 3. Link speed test: Adapter has negotiated link speed correctly or not. -Vishal
