config Routine

The config routine performs all of the processing needed to configure, unconfigure, and read Vital Product Data (VPD) for the adapter.

When this routine is called to configure an adapter, it performs the required checks and building of data structures needed to prepare the adapter for the processing of requests.

When asked to unconfigure or terminate an adapter, this routine deallocates any structures defined for the adapter and marks the adapter as unconfigured. This routine can also be called to return the Vital Product Data for the adapter, which contains information that is used to identify the serial number, change level, or part number of the adapter.
