- Just like Darwin, FreeBSD returns IP_RECVTL, not IP_TTL in the control message when IP_RECVTTL is requested. - Ditto for IP_RECVTOS - FreeBSD does not have IP_PKTINFO - FreeBSD does have IPV6_PKTINFO, but just case don't assume. - The loopback interface on FreeBSD is called lo0, and is not necessarily at index 1. Just make sure that ifNameToIndex and ifIndexToName round-trip without assuming index 1.
