To a certain extent they are supposed to be able to
co-exist.

We weren't careful in the past in some cases, to the point
where the conflicts often very difficult to resolve.  That's
the kind of situation we have here.

I guess I'll put in the following hack for now:

diff --git a/include/linux/if_tunnel.h b/include/linux/if_tunnel.h
index aeab2cb..82c4362 100644
--- a/include/linux/if_tunnel.h
+++ b/include/linux/if_tunnel.h
