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.
