+Description:
+               When the appropriate driver is loaded, it will create a
+               directory per claimed physical PCI slot in
+               /sys/bus/pci/slots/.  The names of these directories are
+               specific to the driver, which in turn, are specific to the
+               platform, but in general, should match the label on the
+               machine's physical chassis.
+
+               The drivers that can create slot directories include the
+               PCI hotplug drivers, and as of 2.6.27, the pci_slot driver.
+
+               The slot directories contain, at a minimum, a file named
+               'address' which contains the PCI bus:device:function tuple.
+               Other files may appear as well, but are specific to the
+               driver.

+Description:
+               If PCI slot directories (as described above) are created,
+               and the physical slot is actually populated with a device,
+               symbolic links in the slot directory pointing to the
+               device's PCI functions are created as well.
