Zero copy receive is a much harder issue, and for that you need more infrastructure; I think the IOAT patches that got merged last night in the post-2.6.17 tree will help for that, but I do not know if what got merged is sufficient already for full support. I hope this answers your question; if not I would like to ask you to explain in more detail what you mean by "enable zero copy"...
