Update the IPv6 example to something that works...

...although this create a race condition pointed by sthen@ where the
other side might try to negotiave IPv6 before it is enable.

This is *another* fallback of the no IPv6 by default policy.  Since
setting an address implicitly brings the underlying interface UP.

And pppoe(4) (which is special) starts singing as soon as it is UP
even if no proto or parent device has been specified.  Obviously this
cannot work.

Better have a working and racy example than a non-working one.
