  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
