Hello,

When I'm using tshark -x I sometimes get the following output:

Is there a way to tell to Wireshark to just display the Frame and not decompress anything?

 There is currently no 6LoWPAN option to disable such decompression and I'm not aware of an option to disable it on a global basis.  So, no, I don't think there's a way to turn that off.
