Thanks, I've fixed this.

You need to create it. It contains compile-time configuration options for 
lwIP which you want to override from the defaults. The defaults can be 
found in include/lwip/opt.h

I have done a port to SAM7X, but it's only within my employer's OS 
(eCosPro), and more importantly being a different OS is presumably not 
what you want. But at least you can rest assured it can work nicely.
