I may be able to do it if it is not too much. It really depends what you need. Many years ago, I ported UDP/IP to Coherent (a UNIX like OS) at user level to support TFTP file transfers. It took me about 2 months. I already had a working Ethernet driver, and I didn't worry about porting all of the features of the IP stack. If you want an estimate for a more fully blown TCP/IP stack, why not post a question on the Linux Kernel mailing list? It would definitely be in the man years to do everything that they've done from scratch, but I recall at one time, someone ported the BSD stack to Linux, so if that person is still monitoring the LKML, they might give you a good idea. If you get a good response, please cross post it back here. Good luck - Jim.
