The first what IPv6 does is [0]. See my previous mail. Also that we should handle on 6LoWPAN packet handler function for receiving "lowpan_rcv" we should do the same, otherwise we parsing PACKET_OTHERHOST sk_buff's and drop these directly in IPv6 layer, which makes no sense. But what I see is that the current behaviour should also work. Instrument the IPv6 delivery function and be sure that the information about PACKET_OTHERHOST was not dropped. - Alex [0] http://lxr.free-electrons.com/source/net/ipv6/ip6_input.c#L72
