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.
