Description

Apparently the DLT is ethernet, but the first header is DOCSIS... Wireshark requires you to manually specify docsis mode by go to Edit, Preferences, Protocols, select Frame, then Treat all frames as Docsis frames.

Docsis has a variable length header due to 0 or more extensions. Need to be able to parse this header to be able to get to the L2+ headers in the frame for decoding/editing.

Recommend a --docsis flag rather then autodetection.
