Chelsio T5/T4 Unified Wire For Linux Page 48
1. Introduction
Chelsio’s T5 and T4 series of Unified Wire Adapters provide extensive support for NIC
operation, including all stateless offload mechanisms for both IPv4 and IPv6 (IP, TCP and UDP
checksum offload, LSO - Large Send Offload aka TSO - TCP Segmentation Offload, and assist
mechanisms for accelerating LRO - Large Receive Offload).
A high performance fully offloaded and fully featured TCP/IP stack meets or exceeds software
implementations in RFC compliance. Chelsio’s T5/T4 engine provides unparalleled performance
through a specialized data flow processor implementation and a host of features designed for
high throughput and low latency in demanding conditions and networking environments, using
standard size Ethernet frames.
TCP offload is fully implemented in the hardware, thus freeing the CPU from TCP/IP overhead.
The freed CPU can be used for any computing needs. The TCP offload in turn removes network
bottlenecks and enables applications to take full advantage of the networking capabilities.
