system memory used by the driver. If too few receive descriptors are used, performance suffers. If too
many receive descriptors are used, the driver unnecessarily consumes memory resources.
o Default = 200
o Range = 100 -— 512
• IPv4 Checksum Offload. Describes whether the device enabled or disabled the calculation of IPv4
checksums.
o Default = Rx/Tx Enabled
o Range = Cannot be disabled
• TCP Checksum Offload (IPv4). Describes whether the device enabled or disabled the calculation of
TCP Checksum over IPv4 packets.
o Default = Rx/Tx Enable
o Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• UDP Checksum Offload (IPv4). Describes whether the device enabled or disabled the calculation of
UDP checksum over IPv4 packets.
o Default = Rx/Tx Enable
o Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• TCP/UDP/IP Checksum Offload (IPv4). Describes whether the device enabled or disabled the
calculation of TCP, UDP, or IP checksum over IPv4 packets. If this TCP/UDP/IP Checksum Offload
(IPv4) property is present, it overrides and disables the TCP Checksum Offload (IPv4), UDP
Checksum Offload (IPv4), and IPv4 Checksum Offload properties.
o Default = Rx/Tx Enable
o Range = Disable; Tx Enable; Rx Enable; Rx/Tx Enable
• Large Send Offload Version 1 (IPv4). Describes whether the device enabled or disabled the
segmentation of large TCP packets over IPv4 for large send offload version 1 (LSOv1).
o Default = Enabled
o Range = Disabled; Enabled
• Large Send Offload Version 2 (IPv4). Describes whether the device enabled or disabled the
segmentation of large TCP packets over IPv4 for large send offload version 2 (LSOv2).
o Default = Enabled
o Range = Disabled; Enabled
• Speed & Duplex. Allows the user to set the connection speed to the network and mode. The Duplex
Mode allows the adapter to transmit and receive network data simultaneously. The adapter is set to
Auto (optimum connection) by default. Set the speed and mode as described below:
o 1 Gb Full Auto. Sets the speed to 1 Gbps and mode to Full-Duplex
o 10 Mb Full. Sets the speed to 10 Mbps and mode to Full-Duplex
o 10 Mb Half. Sets the speed to 10 Mbps and mode to Half-Duplex
o 100 Mb Full. Sets the speed to 100 Mbps and mode to Full-Duplex
o 100 Mb Half. Sets the speed to 100 Mbps and mode to Half-Duplex
o 1000 Mb Full. Sets the speed to 1000 Mbps and mode to Full-Duplex
o 1000 Mb Half. Sets the speed to 1000 Mbps and mode to Half-Duplex
