To me, the obvious answer would be "just don't do that". Each fragment is a distinct packet, so it should not reuse a header that was created for another packet in the first place. > Each call of lowpan_fragment_xmit will have the same DSN value.

Crypto will have to set it's own frame counter there anyway, since reordering in the wpan queue would otherwise cause unexpected packet drops. I don't see that need for the DSN though. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
