Standard Protocol for ethernet to PC data transfer

well, there is a stand alone LWIP stack implementation, but i have 0 experience with that, since i just use the micro/OS which comes with the nios Dev kit

all things considered though, the LWIP stack could do with some good looking over, ive just been looking at the checksum routines in inet.c and ive taken out some rather stupid pieces of code basicly doing nothing or being totally inefficient

didnt give me much more speed though, but clean logical code is a good thing anyway
