Following are some of the examples of the usage of error handled status
in the vendor specific code of the rasdaemon,
1. rasdaemon need not to print the vendor error data reported by the firmware if the
kernel driver already print those information. In this case rasdaemon will only need to store
the decoded vendor error data to the SQL database.
2. If the vendor kernel driver want to report extra error information through
the vendor specific data (though presently we do not have any such use case) for the rasdamon to log.
I think the error handled status useful to indicate that the kernel driver has filled the extra information and
rasdaemon to decode and log them after extra data specific validity check.
