[submitter in bcc]

This is an old bug reported on Ubuntu as "[r8169] Kernel loop PCIe Bus
Error on RTL810xE"
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2015670).

Seems like we're seeing about 10 AER Correctable Error log messages
like this per second:

  pcieport 0000:00:1d.0: AER: Multiple Correctable error message received from 0000:01:00.0
  r8169 0000:01:00.0: PCIe Bus Error: severity=Correctable, type=Physical Layer, (Receiver ID)
  r8169 0000:01:00.0:   device [10ec:8136] error status/mask=00000001/00006000
  r8169 0000:01:00.0:    [ 0] RxErr                  (First)

This is on a Dell Inc. Inspiron 3793/0C1PF2, BIOS 1.30.0 03/07/2024
with Realtek RTL810xE NIC.

Submitter tested a patch
(https://bugzilla.kernel.org/attachment.cgi?id=306243&action=diff)
that just masked PCI_ERR_COR_RCVR errors, which masked the problem,
but that patch isn't upstream and seems like a hack.

v6.16 will include ratelimiting for correctable errors, which will
help but it's still not a real solution.

I'm not sure what if anything to do here, I'm just forwarding to the
mailing list so it's not completely forgotten and to make it visible
to search engines.
