EtherNut is a full, open source TCP/IP stack.

Another option is lwIP:

and uIP:

If your device requires/supports UDP packets, you may only need a 
subset (ARP, ICMP and UDP) that you could fairly easily implement 
resulting in a smaller footprint.  You could even implement DHCP 
(client side) if it was necessary but if you can live with a fixed IP 
address you won't even need that.

If your device requires TCP, you're probably better off using 
something like EtherNut that's already working and tested.

As far as the Ethernet hardware, you could look at the PacketWhacker 
or NICki for prototyping:
