Actually, MAC address has nothing to do with device naming/ordering at
all. Often systems will have onboard NICs in ascending MAC address
order, but that's not a requirement, and I've seen systems not do
that. And once you get to add-in vs onboard, BIOS wouldn't be able to
enforce such an ordering anyhow (in general).
But yes, you raise the point that, without using MAC-assigned names or
another naming mechanism designed to cope with this, adding or
removing a card can cause a difference in device enumeration, and thus
name.
