Hi, all -

The current version of LWiP doesn't support IP_PKTINFO. I've conversed with the folks who maintain this system, and they've indicated that it's working for IPv4 in this version:

https://git.savannah.nongnu.org/git/lwip.git

It's not a really big deal, but it would be nice to have IP_PKTINFO available. Are there any plans to update the LWiP component in the esp-idf?

Hi, WiFive -

Thanks for the answer. According to the developers, 2.0.3 doesn't have the IP_PKTINFO feature I was hoping for:

As I said, it's not a huge deal, but it'd be nice to have at some point.

Well it will probably be easier to merge the extra changes yourself once it is officially at 2.0.3
