The QLogic 8100 Series Adapter offloads the processing of several common 
protocols onto its hardware; this saves host CPU cycles, increases performance, 
and reduces CPU use. The QLogic 8100 Series Adapter supports the following 
offload types:



Checksum offload—The QLogic adapter supports checksum offloads for IP, 
TCP (IPv4, IPv6), UDP (IPv4, IPv6) packets, and the IPv4 header. The 
ChecksumOffloadSupport parameter is enabled by default and can be 
disabled on the Windows Advanced property pages for the QLogic 10Gb 
PCI Ethernet adapter using Windows Device Manager. For information 

UDPChecksumO
ffloadIPv4

Computes (Tx) or verifies 
(Rx) the UDP checksum of 
packets for IPv4. This 
parameter can improve per-
formance and reduce CPU 
use. With Offloading 
enabled, the adapter com-
putes or verifies the check-
sum for the operating 
system.
