I agree with Dave, this should be enabled by default in OpenWRT.
In Matthieu's branch, this was a compile-time option. In 1.6.0, it's
a runtime option, and should be enabled when you know that your kernel
is recent enough.
We should be testing for kernel support automatically. I had some code
that simply tested for 3.11 or higher, but Matthieu nacked it -- he's
working on something smarter.

Go for it, Gabriel.
We're discussing that right now by private mail. I believe that this
patch is incorrect, since it puts routes with ::/128 on the wire. Such
routes should never appear either on the wire or in the RIB, they are
a FIB-only creature.
(i) making sure that you've got a non-specific default route in your
(ii) automatically synthesising ::/128-sourced FIB entries when we have
a destination prefix with no associated non-specific routes;
(iii) automatically syntesising a ::/128-sourced default route under
(i) is obviously the "right" solution, but it puts some constraints on the
network. (ii) and (iii) work around the issue, but they're just hacks,
and I'm not quite sure what the semantics should be.
