I think I have an idea about what's the problem. It would be interesting to
test it on Udp sockets, if they could do a connect ... :)

Anyway, it's about the fact that a TCP socket shouldn't "bind" to both IPv4
*and* IPv6, but if they do bind on IPv6 they can still receive "pseudo-IPv4"
connections. That's disturbing. I'll try to scavenge more the thing.

Dual stack nodes should be forbidden (in general, not only in ns-3).
