Actually W5100 chip can do IP raw and even MAC raw (but in socket 0 only):

So I guess it should be possible to write a standard packet driver or something like that...

Prototyping is good, and it's also good that it can send raw packets. I'd be surprised if it could not.

I've not written a packet driver yet but I'm not too worried about that; there are plenty of old examples laying around. Having a packet driver will enable it to work with all of the existing TCP/IP software.
