I was wondering with the need to support IPv6, http and tls and the
various components whether we wouldn't just be better off using LwIP
[1][2]>, it gives us basically everything we need for IPv6, HTTP boot
and other things we need, and is used on microcontrollers (I came
across it recently when playing with micropython) so it's small. I
feel it would save a lot of time maintaining an independent IP stack
and being used a cross a bunch of different projects is quite widely
used/developed. Thoughts?
