Decode HPE OEM record 236: ProLiant HDD Backplane.
Generally when HPE updates an OEM record, it adds new fields to the end
of the record and updates the record length to reflect the fields added.
This makes explicit checking of record version unnecessary as the length
field implicitly encodes it.
However, sometimes records are changed in a non-backward compatible way
as a field gets redefined from one version to the next. OEM 236 is such
an example.
Going forward, we believe the likelihood of non-backwards compatible
changes will increase.
The approach taken in this series is to use the Type 1 "Product Name"
in addition to the "Manufacturer" to determine the Generation and
hence revision of OEM record to use in decoding records that have
non-backwards compatible changes.
Note: This patch series does not address the ordering issue of OEM
records. So OEM records that appear before Type 1 records
will not be decoded.
