There is need to assign DLT_LAPB value for capturing of the X.25 LAPB traffic and decoding it in the WireShark Protocol Analyzer.
So would the packet data in a DLT_LAPB capture start with the address field of the LAPB header, followed by the Control field, followed by the Information field if any? Or would it also contain an extra flag to indicate whether the packet is a DTE->DCE or DCE->DTE packet?
Would the packets include the CRC at the end?(I'm assuming they would *not* contain the flag octets at the beginning and the end, and that all bit-stuffing would have been removed.)
