I belive this is due to the old NIC being included
into /etc/udev/rules.d/70-persistent-net.rules. AFAIK, each time the
system sees a NIC, it inserts a entry there, thus recording a 'static'
name ethN for the card, thus allowing per-card configuration. I _think_
you can safely remove the entries referring to the older cards and
rename the one you have now (the last one) as eth0, but check the
udev(7) man page to be sure.
