Earlier quoted context omitted.

Note: the ethernet chip _is_ present. In this article (anandtech) they look at Gigabit Ethernet performance and benchmark it at 925-928 Mbps - using the _Thunderbolt_ adapter. Over at the iFixit teardown (step #13), you can see that the ethernet chip is present on the I/O board: "Broadcom BCM57100 series Gigabit Ethernet + Memory Card reader controller" http://www.ifixit.com/Teardown/MacBook-Pro-with-Retina-Displ...

I'd like to see a teardown of the adapter. My understanding of thunderbolt is it's not going to carry ethernet signals. There's another ethernet chip in the adapter (I think). The one on the motherboard is there primarily for the smart card reader and because it allows Apple to use the same chip on the laptops that do have ethernet jacks.
