Hi ..

 I'm working on a project which involves a design that has NiOS II
processor, DDRSDRAM, SSRAM, a custom Ethernet MAC and other components and
I've to run an application on it.. I use NiOS II embedded Evaluation
board(Cyclone III), quartus 8.1 web edition. 

Since I'm new to Altera, I would like to start with a simple design with
an ethernet MAC , then  send and recieve packets through it. I'm not strong
in Ethernet concepts too. I feel that the design with TSE MAC and socket
server example are too high at this level of me to understand.

 So can anyone send me a design  which has a MAC and also tell me how to
send and recieve packets over it? If possible, can you send me supporting
documents for mastering the concepts of ethernet. 

Thanks and Regards
Renu
