We need to think a bit more about this.
We are essentially now saying that one can only configure
tunnels 3 levels deep, and no more.
I can guarentee you someone out there uses at least 4,
perhaps more.
And those people will be broken by the new limit.
So putting this into net-2.6 with such a low limit will
be quite dangerous.
