You mean currently driver does not clear fatal errors now, and it is
a problem? Any error reported?
Hi Sathyanarayanan,
No error reports yet, I just changes the behavior back to what it was
before commit e7b0b847de6d ("PCI/AER: Clear only ERR_NONFATAL bits
during non-fatal recovery"), because this commit change the original
function in commit bf2a952d31d2 ("NTB: Add IDT 89HPESxNTx PCIe-switches
support").
Also, I am wondering why is it required to clear errors during init
code. Is it a norm?
I think there is no need to clear errors during init code.
