Use dev_printk like format.
Sample (real machine + dummy error injected by aer-inject):
- Before:
+------ PCI-Express Device Error ------+
Error Severity : Corrected
PCIE Bus Error type : Data Link Layer
Bad TLP :
Receiver ID : 2800
VendorID=8086h, DeviceID=1096h, Bus=28h, Device=00h, Function=00h
+------ PCI-Express Device Error ------+
Error Severity : Corrected
PCIE Bus Error type : Data Link Layer
Bad TLP :
Bad DLLP :
Receiver ID : 2801
VendorID=8086h, DeviceID=1096h, Bus=28h, Device=00h, Function=01h
Error of this Agent(2801) is reported first
- After:
pcieport-driver 0000:00:02.0: AER: Multiple Corrected error received: id=2801
e1000e 0000:28:00.0: PCIE Bus Error: severity=Corrected, type=Data Link Layer, id=2800(Receiver ID)
e1000e 0000:28:00.0: device [8086:1096] error status/mask=00000040/00000000
e1000e 0000:28:00.0: [ 6] Bad TLP
e1000e 0000:28:00.1: PCIE Bus Error: severity=Corrected, type=Data Link Layer, id=2801(Receiver ID)
e1000e 0000:28:00.1: device [8086:1096] error status/mask=000000c0/00000000
e1000e 0000:28:00.1: [ 6] Bad TLP
e1000e 0000:28:00.1: [ 7] Bad DLLP
