Large Send Offload (IPv4 and IPv6)
Sets the adapter to offload the task of segmenting TCP messages into valid Ethernet frames. The maximum frame size
limit for large send offload is set to 64,000 bytes.
Since the adapter hardware is able to complete data segmentation much faster than operating system software, this fea-
ture may improve transmission performance. In addition, the adapter uses fewer CPU resources.

TCP Checksum Offload (IPv4 and IPv6)
Allows the adapter to verify the TCP checksum of incoming packets and compute the TCP checksum of outgoing pack-
ets. This feature enhances receive and transmit performance and reduces CPU utilization.
With Offloading off, the operating system verifies the TCP checksum.
With Offloading on, the adapter completes the verification for the operating system.

UDP Checksum Offload (IPv4 and IPv6)
Allows the adapter to verify the UDP checksum of incoming packets and compute the UDP checksum of outgoing pack-
ets. This feature enhances receive and transmit performance and reduces CPU utilization.
With Offloading off, the operating system verifies the UDP checksum.

Thermal Monitoring
Adapters and network controllers based on the Intel® Ethernet Controller I350 (and later controllers) can display tem-
perature data and automatically reduce the link speed if the controller temperature gets too hot.
