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