In order to limit the CPU utilization without impacting the overall throughput, we recommend that you load the driver as follows: This reduces interrupt load on the system and can lower CPU utilization under heavy load, but will increase latency as packets are not processed as quickly. Reverse speed test with iperf from that server to this one yields the same performance. Instructions on updating ethtool can be found in the section Additional Configurations later in this document.

Linux* Base Drivers for Intel® Ethernet Network Connection

Driver information can be obtained using ethtool, lspci, and ifconfig. If CPU utilization is not a concern, use default driver settings. This parameter is different than other parameters, in corporatin it is a single not 1,1,1 etc.

A link between two EEE-compliant devices will result in periodic bursts of data followed by periods where the link is in an idle state.

CONFIG_IGB: Intel(R) 82575/82576 PCI-Express Gigabit Ethernet support

Jumbo Frames support is enabled by changing the MTU to a value larger than the default of After installing the driver, if your Intel Ethernet Network Connection is not working, verify that you have lntel the correct driver.

MTU designates the frame size.

ingel Increasing this value adds extra latency to frame reception and can end up decreasing the throughput of TCP traffic. This information is accessed by the hardware.

This parameter is supported only onand later adapters. If you are required to use a 2. The default value for each parameter is generally the recommended setting, unless otherwise noted.

This has a possible negative performance impact, which may be compensated for by allocating more descriptors using the TxDescriptors module parameter.

Linux Driver for Intel® Gigabit Network Connections

Interrupt moderation must be used to avoid interrupt storms while the driver is processing one interrupt. Reverse speed test with iperf from that server to this one yields the same performance. IntMode controls allow load time control over the type of interrupt registered for by the driver.

EEE 1 enabled A link between two EEE-compliant devices will result in periodic bursts of data followed by periods where the link is in an idle state. If during this process you are asked for the driver or module name, the name for the Linux Base Driver for the Gigabit Family of Adapters is igbvf. LLI allows for immediate generation of an interrupt upon processing receive packets that match certain criteria as set by the parameters described below.

All driver structures, in-memory queues, and receive buffers will be allocated on the node specified. To solve this issue, create the inte. To reduce the impact, the packet buffer sizes and relevant flow control settings are modified accordingly. An interrupt is sent to the PF driver notifying it of the spoof attempt.

Can be either one or two-directional. Defines the direction in which data is allowed to flow. Useful only if TxIntDelay is non-zero, this value ensures that an interrupt is generated linuc the initial packet is sent on the wire within the set amount of time.

In addition the number of queues available for RSS is limited if this is set to 1 or greater.

Allows Phy to turn off in lower power states. If a system based on the, or controller is connected to a hub, the Activity LED will blink for all network traffic present on the hub. Load the module using either the insmod or modprobe command: The user should run the Linux firmware kit from http: Other distributions may store this setting in a different location.

The user can enable it at compile time to add support for LRO from the driver. This will impart the greatest chance for your system to consume less power.
