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.
The previous email represents my own personal opinion.

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.
