Sounds fun! Were you already familiar with networking/Ethernet when you started? If not, which resources - if any - did you use to get a broad overview of everything involved? My knowledge of networking ends at a very basic understanding of the OSI model, and I am very interested in taking a deep dive into the networking world.

I'll tell you how I learned, I got thrown head-first into a network switch design. I knew almost nothing about networking.

The most useful resource while I was learning was RFC1812 "Requirements for IPv4 Routers" [1]

Its an ancient document written the same year I was born detailing how future routers should be built on this relatively new thing called the internet. The language is highly approachable and detailed, often explaining WHY things are done. It is an awesome read.

To be honest you don't need to finish it. I only read the first few chapters, but I googled EVERYTHING I did not understand. The first few paragraphs took several hours. Talk to LLM's if you need a concept explained. Take notes. In a few days you'll have a very solid grasp.

Wireshark, plus a book about using Wireshark. I have "Wireshark Network Analysis", which looks to be shockingly expensive right now - to be fair, it's worth whatever price, but maybe not while you're speculativey getting your toes wet - and there are others out there. I am nowhere near an expert (I've only worked through about 1/3 of that book - just enough to solve the problem I had at the time!), but that's what's taught me what I know, and I know can take me further.

I wasn't at all, to be honest. I joined a multidisciplinary team and they were short an Ethernet SME. I said I'd be happy to just in feet first and learn, as I was desperate to get into anything and everything FPGAs at the time, having become bored by the CPU world I resided before. Mostly I learnt everything through building stuff using our User Guides. Everything else was just reading; the Ethernet spec, random Cisco stuff online, Wikipedia, etc. I just searched for any word or acronym I didn't understand, and read up on it (meaning of 64/66b encoding, PCS vs PHY vs MAC, PTP, OTN, FlexE, FEC, ANLT, and so on). Once you get passed the TLAs, it's actually pretty simple (except for PTP - that's the bane or my working life at the moment).
