Flow Control
Enables or disables the receipt or transmission of PAUSE frames.
PAUSE frames allow the network adapter and a switch to control the transmit rate.
The side that is receiving the PAUSE frame momentarily stops transmitting.
Auto
(default). Receive and transmit PAUSE frame functions are optimized.
This option indicates that the adapter automatically adjusts the flow control
settings for optimal performance, and its purpose is not enabling auto
negotiation of the flow control parameters.
Disable
. Receive and transmit PAUSE frame functions are disabled.
Rx Enabled
. Receive PAUSE frame is enabled.
Rx & Tx Enabled
. Receive and transmit PAUSE frame are enabled.
Tx Enabled
. Transmit PAUSE frame is enabled.
IPv4 Checksum Offload
Normally, the checksum function is computed by the
protocol stack. When you select one of the Checksum Offload property values
(other than None), the checksum can be computed by the network adapter.
Rx Enabled
.
Enables receive TCP/IP/UDP checksum offload.
Tx Enabled
.
Enables transmit TCP/IP/UDP checksum offload.
Tx/Rx Enabled
(default). Enables transmit and receive TCP/IP/UDP
checksum offload.
None
.
Disables checksum offload.
IPv4 Large Send Offload
Normally, the TCP segmentation is done by the
protocol stack. When you enable the Large Send Offload property, the TCP
segmentation can be done by the network adapter. The default setting for this
property is Enabled. This property is only available for QLogic 8400/3400 Series
adapters.
IPv6 Checksum Offload
Normally, the checksum function is computed by the
protocol stack. When you select one of the Checksum Offload property values
(other than None), the checksum can be computed by the network adapter.
Rx Enabled
.
Enables receive TCP/IP/UDP checksum offload.
Tx Enabled
.
Enables transmit TCP/IP/UDP checksum offload.
Tx/Rx Enabled
(default). Enables transmit and receive TCP/IP/UDP
checksum offload.
None
.
Disables checksum offload.
IPv6 Large Send Offload
Normally, the TCP segmentation is done by the
protocol stack. When you enable the Large Send Offload property, the TCP
segmentation can be done by the network adapter. The default setting for this
property is Enabled. This property is only available for QLogic 8400/3400 Series
adapters.
