> john1988 and Noam Rathaus reported that vti6_init_net() does not set the
> netns_immutable flag on the per-netns fallback tunnel device (ip6_vti0).
> 
> Other similar tunnel drivers (like ip6_tunnel, sit, ip6_gre, and ip_tunnel)
> correctly set this flag during their fallback device initialization to
> prevent them from being moved to another network namespace.
