Jike Song asked what if you attach a PCIe endpoint that has an extended
tags quirk to think about the reverse direction. That's why, I was walking
the entire bus. 

We can maybe hold onto putting such a generic code until such a device
with quirk actually shows up.

I'll pull your suggestion into a patch, give it a try and then post the
next version.
