/* Retrieve information about PCI subsystem through libpci library from
 pciutils package. This should be possible on Linux, BSD and AIX.
 
 This code is based on example.c, lspci.c and pci.ids from pciutils.
 
 Device classes, subclasses and programming interfaces are hardcoded
 here, since there are only few of them, and they are important and
 should their names be translated.
