Great, I'm glad to hear you're planning on implementing this for more than 
just TCP.

I understand your desire to have the basic idea accepted with only TCP 
implemented - and that is fine with me - but I would like to see support for 
all of the protocols merged at the same time.  In other words, seeking the 
basic ACKs for TCP from the davem, et al is okay but I'd like to defer merging 
TCP support until you have everything implemented and ready to be merged.
