Just drop it in 802.15.4 6LoWPAN for testing case. Maybe, you hit the problem at [0]. This occurs when "Type 131 - Multicast Listener Report" arrived. [1] Don't know much about Multicast Listener Report at the moment and if this is really necessary for your use case. Just give it a try. It's something with multicast and I know there is some issue right now. - Alex [0] http://lxr.free-electrons.com/source/net/ipv6/mcast.c#L1426 [1] http://www.iana.org/assignments/icmpv6-parameters/icmpv6-parameters.xhtml#icmpv6-parameters-codes-9 -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
