   4 Description:
   5                 A file named vpd in a device directory will be a
   6                 binary file containing the Vital Product Data for the
   7                 device.  It should follow the VPD format defined in
   8                 PCI Specification 2.1 or 2.2, but users should consider
   9                 that some devices may have malformatted data.  If the
  10                 underlying VPD has a writable section then the
  11                 corresponding section of this file will be writable.
