ifconfig -a should show you all the interfaces present regardless of
state

I've come across more than one instance of udev deciding to rename
network interfaces on upgrades and the like. 

On Debian variants it does so
in /etc/udev/rules.d/70-persistent-net.rules

Its safe to delete/rename this file as it should get recreated on boot
if needed.
