About the check flagged by Sashiko: "ip route add help" is fine. iproute2 catches the "help" word and prints the usage before it parses it as a prefix, so the grep works. As a small nit, the other srv6 selftests use "ip route help" without "add". This is not blocking, and I don't think it is worth spinning a v4 just to remove the "add".
