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 endpoint is causing problems, the AER

counters may increment at its link partner (e.g. root port) because the

errors may be "seen" / reported by the link partner and not the

problematic endpoint itself (which may report all counters as 0 as it never

saw any problems).

============================

PCIe Rootport AER statistics

============================

These attributes show up under only the rootports (or root complex event

collectors) 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 include them and are thus cumulative of all the error

messages on the PCI hierarchy originating at that root port.
