Well that was kind of the point in my question below the ---

Is that something we want to be generic? Would we want to have quirks
for the devices where we might *not* want it? 

Anything that *has* a driver for the PF, should have .sriov_configure
already. Anything that doesn't have a driver can (now) use UIO to
enable SR-IOV. So we don't *have* to make it unconditionally
available...
