Hello Martine You did great ! Yes I think that You should send back the beginning of the original fragment at least up to the HL in an icon error and then an abort...
This is the generic problem with errors in 6LoWPAN HC networks . Should the ICMO contain the compressed or uncompressed? To sort out the error which maybe with the compression I believe we must send back the compressed form in ICMP errors .
