I'm seeing this as well. Furthermore, it seems to get in the way of
other interfaces such as wifi, meaning that if you're regularly using a
wifi, every time a new "eth0" interface kicks in you lose connectivity.

To give in idea, currently my laptop has 9 bogus "eth0" interfaces, in
addition to the "right" one (i.e., "ifupdown (eth0)" and another static
one I've configured).

I haven't yet understood when exactly network-manager adds a new one,
but at each resume for suspend I lose connectivity, but not only. For
instance, since the last resume (~1 hour ago) I had to manually disable
a bogus eth0 interface at least 3 times.  As you can imagine, this is
really getting in the way of using my computer productively --- hence my
severity tweaking.

If you've ideas on how I can help you debug the problem, let me know.
Cheers.
