+What: /sys/bus/pci/devices/.../vpd
+Date: February 2008
+Contact: Ben Hutchings <bhutchings@solarflare.com>
+Description:
+ A file named vpd in a device directory will be a
+ binary file containing the Vital Product Data for the
+ device. It should follow the VPD format defined in
+ PCI Specification 2.1 or 2.2, but users should consider
+ that some devices may have malformatted data. If the
+ underlying VPD has a writable section then the
+ corresponding section of this file will be writable.
