v2 > that extends in_pktinfo. Just a thought. The struct would contain both the original and last interface index, and the length as well? And similarly with in6_pktinfo? If there is an agreement that the information would useful also for other things than timestamping, I can try that. If not, I think it would be better to keep it tied to HW timestamping. -- Miroslav Lichvar
