"not enough MMIO BARs for SR-IOV"
or
I think we'll need to go a few rounds on sorting this one out. I don't
have time right now, but I think having this document is important.

Randy, can you wordsmith this one?
I think I'm starting to understand the difference between physfn and
dep_link, but an example would definitely help. It may or may not be
appropriate to put it in.

My understanding is that having 'select' of a config symbol that the

SR-IOV hardware handles config space accesses to virtual functions. No
kernel changes needed for that aspect of it.
