The biggest problem I foresee is that you're trying to do something in hardware which is normally done in software. With Nataraju's list I would say the only point you can realistically accomplish in hardware would be point 1. He also forgot to mention you'll need to handle potentially the Ethernet MAC layer (must be hardware), IP/ARP, and UDP transport which all could be done in hardware. With everything else you're probably going to need to implement a soft core or use an external cpu. Without one, you'd be attempting a monolithic problem that most likely couldn't be built in under a year. So if you end up using a cpu you may as well do all the protocol layers in software along with the parsing to make your task easy.
