TCP Chimney Offload is a networking technology that allows the work associated with moving data across a network to be offloaded from the host computer’s CPU to the network adapter. This helps improve the processing of network data on your computer or server without the need for additional programs or any loss to manageability or security. Programs that are currently bound by network processing overhead will generally scale better when used with TCP Chimney Offload.

Portions of the TCP offload technology in Microsoft products are used under license from Alacritech and may be covered by one or more of the following U.S. Patents: 6,226,680; 6,247,060; 6,334,153; 6,389,479; 6,393,487; 6,427,171; 6,427,173; 6,434,620; 6,591,302; 6,658,480; 6,697,868; 6,751,665; or 6,757,746. Microsoft does not have a license under the Alacritech patents to implement the claimed offloading functionality in hardware. It is expressly agreed and acknowledged that no license is granted under Alacritech patents expressly, by implication, by exhaustion, or otherwise, to use or sell the TCP offload technology in combination with any non-licensed hardware that is specially designed to practice the Alacritech patents.

Translation it’s more of that evil tcp checksum offloading/Broadcom nic stuff that we hate and don’t need.
Do this and then reboot.
