Field Documentation
   unsigned char hwloc_obj_attr_u::hwloc_pcidev_attr_s::bus
       Bus number (yy in the PCI BDF notation xxxx:yy:zz.t).

   unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::class_id
       The class number (first two bytes, without the prog_if).

   unsigned char hwloc_obj_attr_u::hwloc_pcidev_attr_s::dev
       Device number (zz in the PCI BDF notation xxxx:yy:zz.t).

   unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::device_id
       Device ID (yyyy in [xxxx:yyyy]).

   unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::domain
       Domain number (xxxx in the PCI BDF notation xxxx:yy:zz.t). Only 16bits
       PCI domains are supported by default.

   unsigned char hwloc_obj_attr_u::hwloc_pcidev_attr_s::func
       Function number (t in the PCI BDF notation xxxx:yy:zz.t).

   float hwloc_obj_attr_u::hwloc_pcidev_attr_s::linkspeed
       Link speed in GB/s. This datarate is the currently configured speed of
       the entire PCI link (sum of the bandwidth of all PCI lanes in that
       link). It may change during execution since some devices are able to
       slow their PCI links down when idle.

   unsigned char hwloc_obj_attr_u::hwloc_pcidev_attr_s::revision
       Revision number.

   unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::subdevice_id
       Sub-Device ID.

   unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::subvendor_id
       Sub-Vendor ID.

   unsigned short hwloc_obj_attr_u::hwloc_pcidev_attr_s::vendor_id
       Vendor ID (xxxx in [xxxx:yyyy]).
