They're populated in the order they're specified or scanned.
If they're two different drivers (devnp-x, devnp-y), just
start them on the command line or mount them in the desired
order.  If they're chipsets handled by the same driver there
may be a driver specific arg to bind it to a particular
instance.  For example,

io-pkt -d devnp-x pci=0 -d devnp-x pci=1
io-pkt -d devnp-x did=x -d devnp-x did=y

You can also try the 'lan=x' option

io-pkt -d devnp-x did=x,lan=a -d devnp-x did=y,lan=b

Check the docs for the driver in question.
