The VPD-R is a readonly area of the PCI Vital Product Data region.
There are some standard keywords for serial number, manufacturer,
and vendor-specific values. Dell Servers use a vendor-specific
tag to store number of ports and port mapping of partitioned NICs.
info = VPD-Info string
PN = Part Number
SN = Serial Number
MN = Manufacturer ID
Vx = Vendor-specific (x=0..9 A..Z)
This creates a sysfs subdirectory in the pci device: vpdattr with
'info', 'EC', 'SN', 'V0', etc. files containing the tag values.
Added pci.h patch
