  20 MISC_SMBIOS_TABLE_FUNCTION (
  21   MiscPortInternalConnectorDesignator
  22   )
  23 /*++
  24 Description:
  25
  26   This function makes boot time changes to the contents of the
  27   MiscPortConnectorInformation (Type 8).
  28
  29 Parameters:
  30
  31   RecordType
  32     Type of record to be processed from the Data Table.
  33     mMiscSubclassDataTable[].RecordType
  34
  35   RecordLen
  36     Size of static RecordData from the Data Table.
  37     mMiscSubclassDataTable[].RecordLen
  38
  39   RecordData
  40     Pointer to copy of RecordData from the Data Table.  Changes made
  41     to this copy will be written to the Data Hub but will not alter
  42     the contents of the static Data Table.
  43
  44   LogRecordData
  45     Set *LogRecordData to TRUE to log RecordData to Data Hub.
  46     Set *LogRecordData to FALSE when there is no more data to log.
  47
  48 Returns:
  49
  50   EFI_SUCCESS
  51     All parameters were valid and *RecordData and *LogRecordData have
  52     been set.
  53
  54   EFI_UNSUPPORTED
  55     Unexpected RecordType value.
  56
  57   EFI_INVALID_PARAMETER
  58     One of the following parameter conditions was true:
  59       RecordLen was zero.
  60       RecordData was NULL.
  61       LogRecordData was NULL.
