Debugging PCIE AER code can be very difficult because it is hard to

based error injection tool, which can fake various PCIE errors with a

The patch fakes AER error by faking some PCIE AER related registers
and an AER interrupt for specified the PCIE device.

Yes. I forget to change this. But the directory to put aer-inject tar
ball is subject to be changed. I am contacting with kernel.org ftp
maintainer for appropriate place.
I see.
By the way, thank you for this very nice feature!
Thanks,
