[lwip-users] Sizes of lwip structures?

[Peter]

I have partly solved this question, by changing values and recompiling
after each one, and posted it here

https://www.eevblog.com/forum/microcontrollers/any-experts-on-lwip-and-the-netconn-api-(not-looking-for-free-can-pay)/msg4342318/#msg4342318

It's a pity this list is practically dead. It gets a lot of google
hits, but almost nobody replies.

I wonder if there is a document anywhere describing in a readable
manner LWIP design. Well nobody is going to reply to that question,
too :)
