/**
  This is a macro defined function, in fact, the function is
  MiscPortInternalConnectorDesignatorFunction (RecordType, RecordLen, RecordData, LogRecordData)
  This function makes boot time changes to the contents of the
  MiscPortConnectorInformation.

  @param  MiscPortInternalConnectorDesignator  The string which is used to create
                                               the function
  The Arguments in fact:
  @param  RecordType                           Type of record to be processed from
                                               the Data Table.
                                               mMiscSubclassDataTable[].RecordType
  @param  RecordLen                            Size of static RecordData from the
                                               Data Table.
                                               mMiscSubclassDataTable[].RecordLen
  @param  RecordData                           Pointer to RecordData, which will be
                                               written to the Data Hub
  @param  LogRecordData                        TRUE to log RecordData to Data Hub.
                                               FALSE when there is no more data to
                                               log.

  @retval EFI_SUCCESS                          *RecordData and *LogRecordData have
                                               been set.
  @retval EFI_UNSUPPORTED                      Unexpected RecordType value.
  @retval EFI_INVALID_PARAMETER                One of the following parameter
                                               conditions was true: RecordLen was
                                               zero. RecordData was NULL.
                                               LogRecordData was NULL.
