This option can be overridden to 1 if there are not sufficient interrupts available. Taxes and shipping, etc. You can enable it on an em interface using ifconfig 8. The default value is for adapters newer than , and for older ones. If both Duplex and the link partner are set to auto-negotiate, the board auto-detects the correct duplex. This value delays the generation of receive interrupts in units of 1. Then select the name of the specified base driver:

Using Jumbo frames at 10 or Mbps is not supported and may result ljnux poor performance or loss of link. Listing of these RCP does not constitute a formal pricing offer from Intel.

Ubuntu Manpage: em — Intel(R) PRO/ Gigabit Ethernet adapter driver

It works by aggregating multiple incoming packets from a single stream into a larger buffer intdl they are passed higher up the networking stack, thus reducing the number of packets that have to be processed. This value coincides with the maximum Jumbo Frames size of Search examples You can search our catalog of processors, chipsets, kits, SSDs, server products and more in several ways.

To resolve this issue build the driver step 4 above using the command:. Strip the CRC from received packets before sending up the network stack. The identification LEDs of the adapters supported by the em driver can be controlled via the led 4 API for localization purposes.


CONFIG_E1000: Intel(R) PRO/1000 Gigabit Ethernet support

This issue is fixed in kernel version 2. The driver utilizes the ethtool interface for driver configuration and diagnostics, as well as displaying statistical information. A descriptor describes a data buffer and attributes related to the 882546gb buffer.

The default value for each parameter is generally the recommended setting, unless otherwise noted.

Please work with your appropriate Intel representative to obtain a formal price quotation. Furthermore it supports TCP segmentation offload TSO on all adapters but those based on theand controller chips.

Expected Discontinuance is an estimate of when a product will begin the Product Discontinuance process.

If you encounter the problem in an adapter, and the chipset is an based one, you can verify that your adapter needs the fix by using ethtool: Refer to the Speed and 8254gb section of this readme for more information on the AutoNeg parameter.

The Linux Base Inttel support the 2. Defines the direction in which data is allowed to flow. To learn the proper way to configure a network device for your system, refer to your distribution documentation.

Doing so can impact Tx performance. Then follow the appropriate steps for building, installing, and configuring the driver.

Degradation in throughput performance may be observed in some Jumbo frames environments. These correspond to the following product names: If you experience loss of packets, lower the MTU size.


Instructions on updating ethtool can be found in the section Additional Configurations later in this document. Node 0-n 0 – n: The information herein is provided “as-is” and Intel does not make any representations or warranties whatsoever regarding accuracy of the information, nor on the product features, availability, functionality, or compatibility of the products listed.

We recommend the newer 2. This parameter is supported only on adapters using copper connections.

If both Duplex and the link partner are set to auto-negotiate, the board auto-detects the correct duplex. Alternatively, you can use ethtool version 1. EEE support requires autonegotiation. Our goal is to make the ARK family of tools a valuable resource for you. It is most effective in an environment with many small transactions.

When ee is loaded inyel default settings and multiple adapters are in use simultaneously, the CPU utilization may increase non-linearly.
