Without answering your specific question, but addressing $subject, what
problem is caused by the PCI device order you see?
You can use ETHTOOL_GDRVINFO to get the PCI bus info for an ethernet
interface, so you know at all times what device is associated with what
PCI device. And among other ways you are notified of device
addition/removal by the execution of /sbin/hotplug for each ethernet
interface.
