Comment 72 for bug 432205

@Emmanuel Touzery, @Nicolai_J.

You are completely wrong on your point. But, as users, you might not
know, and it's OK. You might also be surprised to know that one
network card can have several IP addresses, and it is pretty well
reasonable and sane setup for some networks.

What I am afraid of is that developers of NetworkManager think like
you (https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/290639/comments/6)
It would be very disturbing if they think we ask for some rare and
unusual thing just out of curiosity. It must be understood that this
is a *real* bug, it makes a lot of trouble for many people here, just
not everyone is writing about this. If you only knew how mad we become
working this bug around on hybrid modems with our dumb monopolist
providers requiring bridge-mode and ceasing technical support
otherwise!

I'd like to thank Yigit Güneli for such clear explanation.

@dobee: Yes, there must be option to turn off or turn on ethN
connections, independently. And there must be an option to turn on or
turn off PPP connections, also independently on any other connections,
whether PPP or Ethernet ones. That would be right.
