MISC_SMBIOS_TABLE_FUNCTION (\r
  MiscPortInternalConnectorDesignator\r
  )\r
/*++\r
Description:\r
\r
  This function makes boot time changes to the contents of the\r
  MiscPortConnectorInformation (Type 8).\r
\r
Parameters:\r
\r
  RecordType\r
    Type of record to be processed from the Data Table.\r
    mMiscSubclassDataTable[].RecordType\r
\r
  RecordLen\r
    Size of static RecordData from the Data Table.\r
    mMiscSubclassDataTable[].RecordLen\r
\r
  RecordData\r
    Pointer to copy of RecordData from the Data Table.  Changes made\r
    to this copy will be written to the Data Hub but will not alter\r
    the contents of the static Data Table.\r
\r
  LogRecordData\r
    Set *LogRecordData to TRUE to log RecordData to Data Hub.\r
    Set *LogRecordData to FALSE when there is no more data to log.\r
\r
Returns:\r
\r
  EFI_SUCCESS\r
    All parameters were valid and *RecordData and *LogRecordData have\r
    been set.\r
\r
  EFI_UNSUPPORTED\r
    Unexpected RecordType value.\r
\r
  EFI_INVALID_PARAMETER\r
    One of the following parameter conditions was true:\r
      RecordLen was zero.\r
      RecordData was NULL.\r
      LogRecordData was NULL.\r
