But this is still needed? I mean, in nft_fib_netdev_eval there are only
2 functions being called for IPv6 protocol : nft_fib6_eval and
nft_fib6_eval_type. Both are already protected by this current patch.

Is your 1st suggestion about this patch, or you think it's better to
move this change to nft_fib_netdev_eval ?

Best regards,
