An experienced developer could port IP, UDP, and TCP to an existing
embedded system that already has an ethernet (or whatever lower layer
you need) driver in a few weeks. 

You'll need to grab appropriate files from /usr/src/sys/netinet as
well as the socket and mbuf related files from /usr/src/sys/kern
and then connect it to the network driver for your physical interface.
