  28 MISC_SUBCLASS_TABLE_FUNCTION (
  29   MiscPortInternalConnectorDesignator
  30   )
  31 /*++
  32 Description:
  33
  34   This function makes boot time changes to the contents of the
  35   MiscPortConnectorInformation (Type 8).
  36
  37 Parameters:
  38
  39   RecordType
  40     Type of record to be processed from the Data Table.
  41     mMiscSubclassDataTable[].RecordType
  42
  43   RecordLen
  44     Size of static RecordData from the Data Table.
  45     mMiscSubclassDataTable[].RecordLen
  46
  47   RecordData
  48     Pointer to copy of RecordData from the Data Table.  Changes made
  49     to this copy will be written to the Data Hub but will not alter
  50     the contents of the static Data Table.
  51
  52   LogRecordData
  53     Set *LogRecordData to TRUE to log RecordData to Data Hub.
  54     Set *LogRecordData to FALSE when there is no more data to log.
  55
  56 Returns:
  57
  58   EFI_SUCCESS
  59     All parameters were valid and *RecordData and *LogRecordData have
  60     been set.
  61
  62   EFI_UNSUPPORTED
  63     Unexpected RecordType value.
  64
  65   EFI_INVALID_PARAMETER
  66     One of the following parameter conditions was true:
  67       RecordLen was zero.
  68       RecordData was NULL.
  69       LogRecordData was NULL.
