This parameter is different than other parameters, in that 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. Allows changing the interrupt mode at module load time, without requiring a recompile. Configuring a network driver to load properly when the system is started is distribution dependent. Do not use MSI-X with the 2. Example output of the script:

To solve this issue, create the version. 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 ee. First identify your adapter. Use the ifconfig command to increase the MTU size.

Depending on the available system resources, the request for a higher number of receive descriptors may be denied. The script can be downloaded at http: Clear queue Compare 0. A receive buffer is also allocated for each descriptor and can be either,or bytes, depending on the MTU setting.
Internal stress testing with jumbo frames shows the reliability on some and devices is improved in certain corner cases by disabling the Early Receive feature.
This may increase network latency but also increases the chances that the system will enter a lower power state. This workaround skips resetting the Phy at shutdown for the initial silicon releases of ICH8 systems.
The igbvf driver supports based virtual function devices that can only be activated on kernels that support SR-IOV. Alternatively, you can use ethtool version 1. A link between two EEE-compliant devices will result in periodic bursts of data followed by periods where the linix is in an idle state.
Please contact system intle for more information on specific products or systems.
This is caused by the way the Linux kernel reports this stressed condition. Use the mediaopt option to select full-duplex mode. Your personal information will be used to respond to this inquiry only. RPM functionality has only been tested in Red Hat distributions.
NAPI Rx polling mode is supported in the e driver. It only needs to be set for Jumbo Frames.
Intel® GB Gigabit Ethernet Controller Product Specifications
infel Forcing master or forcing slave mode will improve time-to-link. Used for end of life products. If you currently have the e driver installed and need to install ee, perform the following: TxDescriptors This value is the number of transmit descriptors allocated by the driver.
We refer to these processors as boxed processors. Receive interrupt reduction can improve CPU efficiency if properly tuned for specific network traffic.
The configuration change can be made permanent by adding the line:. Your name and email address will not be added to any mailing list, and you will not receive email from Intel Corporation unless requested.

The user can turn off this parameter in supported chipsets. This parameter is different than other parameters, in that it is a single not 1,1,1 etc. The igbvf driver requires the igb driver, version 2.
If the bytes per second rate is approximately equal, the interrupt rate will drop as low as interrupts per lknux.
Linux* Base Drivers for Intel® Ethernet Network Connection
The install location listed above is the default location. The default operation is auto-negotiate. For situations where low latency is vital such as cluster or grid computing, the algorithm can reduce latency even more when InterruptThrottleRate is set to mode 1.
