My initial idea here was that we could still allow End.BPF when !CONFIG_IPV6_SEG6_BPF, even if the helpers aren't accessible. But indeed, having a homogeneous behavior is probably a better solution, that would make things more clearer for users. > Mathieu, before this gets lost in archives, plan to follow-up on this one? Sure, I have been totally overbooked the last two weeks and will still be for one week or two. I'm planning to send some patches ASAP, there are a few things to improve and debug. iproute2 support has still not been sent upstream as well.
