No. TCP offload support is something on the to-do list. It's just a question of resources and priorities. As much of a mess as that will create, there is potentially a huge upside. The question is, how many people will benefit from it whether there are more pressing issues.

Is this what is preventing Apple from implementing other stateless offloads, such as TCP Segmentation Offload (also known as Large Send Offload)? AFAIK, Darwin/MacOSX is the only major OS kernel to not support TSO these days, and it really hurts your performance.
