 		The symbolic link points to the PCI device sysfs entry of the
 		Physical Function this device associates with.

-What:		/sys/bus/pci/slots/...
-Date:		April 2005 (possibly older)
-KernelVersion:	2.6.12 (possibly older)
-Contact:	linux-pci@vger.kernel.org
-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.
