TCP/UDP Checksum Offload (IPv4)
The TCP/UDP Checksum Offload (IPv4) property enables the network
interface card port to compute the checksum of transmitting IPv4 packets

CPU.
To modify the TCP/UDP Checksum Offload (IPv4) setting, do the
following:
1. Access the Device Manager on your operating system.
See “Accessing Advanced Properties” on page 54.
2. Select TCP/UDP Checksum Offload (IPv4) in the Property box.
The TCP/UDP Checksum Offload (IPv4) window is displayed as
shown in Figure 58.

(IPv4) function for both receiving and transmitting IPv4 packets.
This is the default setting.

function for both receiving and transmitting.
