Yes, well, I tried to investigate this a bit after your last note.
I went through the PCI Express spec, couldn't find it.  Found something
suggestive in one of the chapters (chapter 6.2) but it seemed
unrelated.  A post to LKML was lost at sea, and the Intel contact
never answered back.   I got nervous about the Intel contact: the
goal was not to give other industry competitors a heads-up about
some neat hardware idea that we have and they don't.

A TBD for me is to track down some PCI Express experts and talk
to them & I haven't done that yet.  Any additonal pointers
