Comment 22 for bug 176125

So here's the dilemma:
Either we enable it by default (like Windows 7 does, btw!) and take a few risks (networks are harder to debug, difficulties with applications, etc.) or we disable it and lessen privacy for end-users.

I'd prefer the second option, but only if we had a way of disabling it *easily*, e.g. checkbox like
"[x] Enable Privacy Extension for Autoconf IPv6" somewhere in network-manager (RFC says there MUST be a switch for end users anyway in 3.6).
