I have found and extended Packages/LWIP Wiki page to include
my analysis and pointers to the related sources and examples

https://devel.rtems.org/wiki/Packages/LWIP

I have added pointer to our LwIP port because it is much
more up to date than Joel referenced 2008 port and I think
that separation of target OS and ETHERNET controller drivers
is done better in our port than in actual BB port.
But I have added pointers to BB port as well.

If you have some more suggestions and pointers to information,
please, fill them to the wiki or move my description
onto some other Wiki page if it fits better for holding LwIP
development information.

May it be that you should be a mentor because you know original
RTEMS networking and IO library as one of main authors much
better then me.

Best wishes,
