 348   VendorCode enables vendor to implement vendor-specific firmware image update policy. Null if
 349   the caller did not specify the policy or use the default policy. As an example, vendor can implement
 350   a policy to allow an option to force a firmware image update when the abort reason is due to the new
 351   firmware image version is older than the current firmware image version or bad image checksum.
 352   Sensitive operations such as those wiping the entire firmware image and render the device to be
 353   non-functional should be encoded in the image itself rather than passed with the VendorCode.
 354   AbortReason enables vendor to have the option to provide a more detailed description of the abort
 355   reason to the caller.
