Ethernet on Spartan 3A to send Data to PC

Hello, I have a Problem. 
I need a crashcours in using ethernet on a FPGA. I have the Xilinx
Spartan-3A DSP Starter Kit and have to create a connection to a PC via
Ethernet. My Problem is, I have ISE and EDK, but I have no idea, how to
realize this connection. I couldn't find any Tutorial this way...
I only want to send data to the PC. With 100MBit/s.

Can you give me advises or links to a tutorial where I can learn how to
implement Ethernet?

I try to use MicroBlaze, but if there is any Softprocessor which is better
in this case, please tell me. 

Thanks for your help!
