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. Select one of the following:

Auto (default). PAUSE frame receipt and transmission are optimized.

Disable . PAUSE frame receipt and transmission are disabled.

Rx PAUSE . PAUSE frame receipt is enabled.

Rx/Tx PAUSE . PAUSE frame receipt and transmission are enabled.

Tx PAUSE . PAUSE frame transmission 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. Select
one of the following:

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 Broadcom NetXtreme II
adapters.
Jumbo MTU
Enables the network adapter to transmit and receive oversized Ethernet
frames that are greater than 1514 bytes, but less than or equal to 9000
bytes in length. This property requires the presence of a switch that is able
to process jumbo frames. This property is only available for Broadcom
NetXtreme II adapters.
Frame size is set at 1500 bytes by default. To increase the size of the
received frames, raise the byte quantity in 500-byte increments.
