pci_reset_function() has been around for quite a while, but it has the
limitation that it will only do a bus reset if there are no other reset
mechanisms available and the bus only hosts a single device.  Otherwise,
no, there's no API I'm aware of that would be available on older
kernels, which is why I created the bus/slot reset interfaces we have
today on newer kernels.  Thanks,

Alex
