Dear all,

there seems to be a limitation in current tshark fields output (-e switch). Currently there are not preserved protocol layers/hierarchy and the output fields are generated as flat structure. For simple protocols this behavior is ok, however for complex protocols it could result into ambiguous interpretation. (Additionally the current -e switch is not working together with -x switch (hex dump))

Here is proposed filtering method for -T ek|json output to preserve protocol layers and the related discussion with examples: https://code.wireshark.org/review/#/c/36774/
It sounds reasonable to extend -e switch with --preserve-layers option. Your opinion on this would be very useful.

Thank you and best regards
