The RFC 826 is just the ARP protocol, i.e. the protocol that can give you a MAC address from an IP address. It is not the easiest to read, I'm sure other online resources that can give a more readable information.

There are many (
http://www.faqs.org/rfcs/np.html#eth) of ethernet related rfc. Maybe it's better explained in wikipedia:
http://en.wikipedia.org/wiki/ethernet#physical_layer What do you think is better?

You should have a more detailed look at the UDP offload example, it is well documented.

Yes, I will do that later.
If I try to use triple speed ethernet (without NIOS) then I think I don't need the SOPC Builder, or do I need it? I added triple speed ethernet megafunction. But at the moment I am not sure how to connect all the pins.
In my hardware reference manual I have 16 address lines, but the TSE IP-Core has only 8 address lines...
I guess the data lines are
bidirectional, so I have chosen the pins '
bidir' and assigned them according to the data sheet. But if I connect the
ff_tx_data and ff_rx_data (of the triple speed ethernet core) to the 32 Bit Data-Line, there come errors:
Found I/O cells that do not connect to top-level pins or have illegal connectivity
