take a look at www.maco-engineering.de there is an opencore 10/100 sopc builder component available. you only need an external phy.

the pdf about this core says

"nios processor 33mhz, 100 mbit/s, full-duplex, cross-over cable, pseudo-udp frames, 1.5kb frame length" .... "ethernet performance of about 8

mbyte/s was archived without using any software optimisations"

"nios processor 75mhz, 100 mbit/s, full-duplex, cross-over cable, tcp/ip protocol" ... "ethernet performance of about 5 mbyte/s was archived with some software optimisations (e.g. checksum calculation in hardware)."

i use the 5-in-1 package.

regards.
