Splitting on a comma won't work as desired here, as the function
portion of multi-function devices may include comas.
Leaving the key as pci_dev_str, is probably ok. Otherwise I suggest
constructing the key from template['domain'], template['bus'],
template['slot'], pci_dev_infom['func'] and conditionally
pci_dev_infom['vdevfn'].
IIRC, it doesn't really matter what the key is, as long as it
is unique for a device. Which is why I think that leaving it
as pci_dev_str should be ok.
