The reason stat_display is not working is because DBG_OFF (maybe more) @lwipopts.h is not defined anywhere in lwip's files. Which is not a problem until I added #define LWIP_DEBUG to debug.h

Unfortunately, AVR32 Studio's compiler didn't realize I changed debug.h so it didn't bother to recompile it until I cleaned and rebuild all files.

How should I debfine DBG_OFF, DBG_ON, etc?

That isn't quite what I meant.  To send data do you call tcp_write() or
netconn_write() or send() for example?  If you use tcp_write() directly then
MEMP_NUM_NETBUF will have no effect and is not your problem.

If you call the function to display that stats and it shows nothing then
something is wrong: it should print statistics about the resources used.
You'll have to debug what's gone wrong.
