Oh, this driver doesn't enable SR-IOV and has no PF/VF awareness. Shame
on us, I'll add it to my list unless someone beats me to it.
Still, I think we'd like to be able to reset a VF if only because it
gets the queues back to a pristine state. A VF reset should not affect
any of the other functions.
