MiscPortInternalConnectorDesignatorFunction.c
Abstract:
Create the device path for the Port internal connector designator.
Port internal connector designator information is Misc. subclass type 6
and SMBIOS type 8.

/**
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.
