    Net devices don't show up in /dev. But you can find their names in
/sys/class/net

    You fall in the case of a laptop with two Ethernet interfaces,
therefore you should not disable ethenet renaming but create some udev
rule file in /etc/udev/rules.d. I cannot help you on this point because
there isn't such a rule on my laptop. The default rules are in
/lib/udev/rules.d; you could look in which file the renaming happens,
then copy the file to /etc/udev/rules.d and modify it to set the name to
your convenience.
