It has been one of the top commercial RTOS network stacks for, I think, 20 years. It moved hands a couple of times and now is supported by the Eclipse Foundation and is MIT-licensed. I'd use it over LwIP.
I remember running into some obscure bugs with the NetX BSD socket layer that we ended up fixing in-house. It’s been way too long to dig up the specifics, but it’s great that fixes can now be upstreamed more easily.
Unfortunately, it doesn't seem they have a process for that yet. But I'm sure that will improve. Or the community could take over. It would be nice to get a silicon vendor to pick this up to build a larger community around it.

Yeah, I always had the impression their translation layers were afterthoughts. Never used the BSD one though.
