Wish list the esp-open-lwip based on LWIP v.2

Can you support esp-open-lwip another version that is based on LWIP v.2 ?

Thank you.

Currently, I don't think, I'll find the time for that. Is there any special feature that you would expect from V2 in contrast to the current one?

In the latest Arduino-ESP8266 core version 2.4.1 seem try to move to lwip v.2 . If esp-open-lwip is supported on lwip2, I think it's conviniant for Arduino-ESP8266 or ESP32 based on lwip V.2 too.

You are right. I will look into this,when porting it to the ESP32.

I did some experiements with the v2 stack, but mainly to test IPv6, This doesn't work with the currenty ESP8266 NONOS SDK and so with Arduino. Too many assumptions about IP addresses being 4 bytes in the rest of the code.

The Arduino environment is also not my main focus and I think the IPv4-stuff that I need for routing work quite well in the current version. To my understanding the main differences are in the TCP/UDP area.

Wow! Waiting your excellent job about lwip v2 for ESP32. Thank you.
