[lwip-devel] [bug #61230] Improve Dual-Stack support for getaddrinfo, return both IPv4 and IPv6 results

[Simon Kueppers]

Follow-up Comment #1, bug #61230 (project lwip):

I have been busy and I think I have a good solution. 
I have created a python script to generate reference output of some test cases
for getaddrinfo. I then wrote a C function, that I compiled with lwIP using
the same getaddrinfo calls and then I compared the output to the reference
output of the python script.

See attached the patch to lwIP and the test outputs (can be compared using
diff).
