Furthermore it supports TCP segmentation offload TSO on all adapters but those based on the , and controller chips. The configuration change can be made permanent by adding the line: A whitepaper containing information on how to best configure your platform is available on the Intel website. Ports 1 and 2 don’t show any errors and will pass traffic. The em driver supports the following media options: Let me know if you need more info from my system. Turning on DMA Coalescing may save energy with kernel 2.

If you believe your system needs to disable this style of interrupt, the driver can be built and installed with the command:. If traffic falls in the “Low latency” or “Lowest latency” class, the InterruptThrottleRate is increased stepwise to An interrupt is sent to the PF driver notifying it of the spoof attempt.

To build igb driver with DCA: The driver can limit the amount of interrupts per second that the adapter will generate for incoming packets. This parameter is not supported on the based adapter.

I’ve even downloaded and installed the latest Linux drivers from Intel but still no resolution. The default operation is auto-negotiate.

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: The and based adapters can handle up to descriptors, while others can have up to MSI-X support is required for Multiqueue.


If the link partner is forced to a specific speed and duplex, then this parameter should not be used. This is caused by the way the Linux kernel reports this stressed condition.

Furthermore it supports TCP segmentation offload TSO on all adapters but those based on theand controller chips. Depending on the available system resources, the request for a higher number of receive descriptors may be denied.

Defines the direction in which data is allowed to flow. For this driver version, in order to enable Lniux, the e driver must be loaded prior to shutting down or suspending the system. The Linux base drivers support the 2.

All hardware requirements listed apply to use with Linux.

Each descriptor is 16 bytes. The install location listed above is the default location. Degradation in throughput performance may be observed in some Jumbo frames environments. TxDescriptorStep 1 use every Tx Descriptor 4 use every 4th Tx Descriptor 1 use every Tx Descriptor On certain non-Intel architectures, it has been observed that intense TX traffic bursts of short packets may result in an improper descriptor writeback.

A 82541gl buffer is also allocated for each descriptor and can be either,or bytes, depending on the MTU setting. Selecting an MTU larger than bytes with the ifconfig 8 utility con- figures the adapter to receive and transmit Jumbo Frames. To override the default, use the following compile-time flags. Other distributions may store this setting in a different location. The igbvf driver requires the igb driver, version 2.


If you currently have the e driver installed and need to install ee, perform the following:. In simplified mode the interrupt rate is based on intwl ratio of tx and rx traffic. This will impart the greatest chance for your system to consume less power. In this mode, which operates the same as mode 3, the InterruptThrottleRate will be increased stepwise to for traffic in class “Lowest latency”.

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. When this parameter is used, the Speed and Duplex parameters must not be specified. This driver version supports VLANs.
