+PCIe Device AER statistics
+==========================
+These attributes show up under all the devices that are AER capable. These
+statistical counters indicate the errors "as seen/reported by the device".
+Note that this may mean that if an end point is causing problems, the AER
+counters may increment at its link partner (e.g. root port) because the
+errors will be "seen" / reported by the link partner and not the the
+problematic end point itself (which may report all counters as 0 as it never
+saw any problems).

+============================
+PCIe Rootport AER statistics
+============================
+These attributes showup under only the rootports that are AER capable. These
+indicate the number of error messages as "reported to" the rootport. Please note
+that the rootports also transmit (internally) the ERR_* messages for errors seen
+by the internal rootport PCI device, so these counters includes them and are
+thus cumulative of all the error messages on the PCI hierarchy originating
+at that root port.
