I want to fix 2 points by the patch.
1. For EP devices (such as multi-function EP device) under the same bus,
when one of the EP devices met non-fatal error, should report non-fatal
error only to the error endpoint device, no need to broadcast all of them.
That is the patch (PCI/AER: Report non-fatal errors only to the affected endpoint #4.15)
have done, but current code PATCH [1] broken this.
How do you know a non-fatal affects only the reporting end point? These can
certainly be bus errors, and it's not the first to detect may be affected.
In any case, what harm does the broadcast cause?
What is the PCIe spec rule about AER errors for multi-function devices?
Does it say it needs to be propagated to all functions or each function has
its own unique AER error handler?
