I send traffic from source vm in source VN to destination vm in destination VM.
I have mirror configuration to mirror all packets from source to destination. Tried with both analyser vm and a ubuntu vm i spawned seperately and tried tshark.

The tshark output from the analyser vm is this:

The header is just displayed as data instead of full header.
The wireshark output from the UI decoded the entire header correctly though.
