Feels like some of those #ifdef should have a #else with an ERR or FIXME or something. Or at least a comment saying it's not necessary.
We have similar checks without the FIXMEs in the same source file. If we really want a FIXME here that should probably for the case when IPV6_PKTINFO is not found for whatever reason, but we also don't have any FIXMEs on failures resulting in ICMP over dgram not working at all (e. g., not allowed, that also can be not permitted). So if we want to start with that I think it would make sense to start from earlier failing fallback.
