  12  * PCIe AER Trace event
  13  *
  14  * These events are generated when hardware detects a corrected or
  15  * uncorrected event on a PCIe device. The event report has
  16  * the following structure:
  17  *
  18  * char * dev_name -    The name of the slot where the device resides
  19  *                      ([domain:]bus:device.function).
  20  * u32 status -         Either the correctable or uncorrectable register
  21  *                      indicating what error or errors have been seen
  22  * u8 severity -        error severity 0:NONFATAL 1:FATAL 2:CORRECTED
