Is FLR something that is per-device or a standard PCI mechanism? If
it's the former, than we've basically implemented FLR using this bit
in the config space.
I believe it is a standard mechanism, albeit new, so perhaps many
devices don't implement it.
I don't have a copy of the PCI specification handy. Can you dig up how
it's implemented? I don't see any references in my local documentation
and I couldn't find anything in Linux that referenced it at the PCI level.
