No, it always has been since the 2.4 kernel days when a deterministic
scan order would always give the same name to the same NIC position.
2.6 has always been a matter of chance if you have more than one card
and don't pin with the MAC address (pairs on cards or the motherboard
stay together and keep the order within the set, but the pairs will
swap).
