They are specific to netns because lwtstate->data is interpreted as an u32 *. But I agree that a test is missing against lwtstate->type to ensure that data will be a nsid.
and seems like they should be declared for both CONFIG_LWTUNNEL 'y' and 'n'.
It is outside the "#ifdef CONFIG_LWTUNNEL". I can successfully compile with and without CONFIG_LWTUNNEL.
