Wouldn’t that be RoCE? Or iWarp?

iWARP maybe, but I don't think you want to offload all of TCP to hardware. You want to leave congestion control and all that to software. I don't entirely know if that's why iWARP isn't very popular, but I suspect that's the reason. You want a software TCP stack that can land the data where you want it directly.
