Hi, OK, so the problem seems to be that the capture claims to be a NG Sniffer capture, but wiretap cannot figure out what type it is, so it labels them as WTAP_DLT_LAPB frames, it seems.
The solution would be to declare a Wellfleet DLT type and detect it there, and then have a WellFleet dissector that chews the first two bytes, builds a TVB containing the rest and calls the Etherenet dissector, because the rest seems to be pseudo-Frame-type Ethernet frames.
