Even 1.1.0 is too old. Please upgrade to 1.3.0 (or even 1.3.1 release candidate 
in some weeks) and try again. I'm afraid we cannot help you with such an old 
version as 0.7.1.

To upgrade the version yourself, just download 1.3.0 from 
http://savannah.nongnu.org/projects/lwip (-> go to download section) and 
replace the old 0.7.1 version with the new version. After recompiling your NIOS 
project, and fixing the warnings you get during compiling, it should just work.

Oh, and the stats you printed indicate there are *no* packets received at all. 
This is a bit strange but might be a problem of your old version or port.
