Yes, Wireshark confirmed it, by saying "Dissector bug".  That's what the "bug" in "Dissector bug" means.

The right place to report Wireshark bugs is

        https://gitlab.com/wireshark/wireshark/-/issues

See https://gitlab.com/wireshark/wireshark/-/merge_requests/227

I still have a doubt regarding the C-VID / S-VID encoding. See the MR comment for more details.

it would be great if you could share a pcap containing a packet with a C-TAG or S-TAG IE so as to verify the fix.

Thanks,

Pascal.
