Nicely done! I just spent my last 16h of work time on implementing the reverse: parsing ethernet2 (with vlans!), ipv4+6 & UDP up to an automotive IP protocol. Use case is to understand a proprietary bus capturing stream that forwards ethernet frames (among other things) nested in ethernet frames that I receive on a raw socket. Fun stuff! Wireshark & Chatgpt are invaluable for this kind of task
