Yes, correct. > And the packet content is just a raw LAPD packet, with no extra stuff > added or removed? It depends on what you mean with "no extra stuff". The payload is raw-LAPD but the capture includes the sockaddr_ll header because the dissector needs to know the interface's role in order to correctly interpret the C/R flag. Specifically, both the frame direction (inbound/outbound/sniffed outbound) and the interface's role are included in the sockaddr_ll header. It is somewhat like the approach adopted with IrLAP (IrDA) frames. Of course, I'm open to suggestions, critics, insults :) > OK, I've assigned 177 to DLT_LAPD. Thank you :) Bye, -- Daniele Orlandi
