I have modified the decode_packet function incorporating multiple codeword
segment. Here, I have attached the patch for the required changes. I have
taken the help from jasper code while writing this code, because only the
document is not sufficient to incorporate these changes. I have not tested
this code yet. Once, I test it, I also let you know. If you have any
suggestion on this patch, please let me know.
