Intel Corporation 82576 Linux Driver

Give Feedback

For this driver version, in order to enable WoL, the e driver must be loaded prior to shutting down or suspending the system. RxDescriptors This value specifies the number of receive buffer descriptors allocated by the driver. The driver can limit the amount of interrupts per second that the adapter will generate for incoming packets. Defines the direction in which data is allowed to flow. Forcing master or forcing slave mode will improve time-to-link.

Restarting the system appears to be the only remedy. Connecting the system to a switch or router will filter out most traffic not addressed to the local port.

Other distributions may store this setting in a different location. Interrupt moderation must be used to avoid interrupt storms while the driver is processing one interrupt. WoL will be enabled on the system during the next shut down or reboot.

Linux Base Drivers for Intel Ethernet Network Connection

All interrupts are throttled via interrupt moderation. It does this by writing a value to the adapter that is based on the maximum amount of interrupts that the adapter will generate per second. If the link partner is forced to a specific speed and duplex, then this parameter should not be used. If the system is reporting dropped transmits, this value may be set too high causing the driver to run out of available transmit descriptors.

As the issue addressed by this parameter has never been observed on Intel Architecture platforms, it should not be used on Intel platforms. After installing the driver, if your Intel Ethernet Network Connection is not working, verify that you have installed the correct driver. Intel is not supplying patches against the kernel source to allow for static linking of the driver. For questions related to hardware requirements, see the documentation supplied with your Intel Gigabit adapter. For questions related to hardware requirements, sony dpp-fp30 drivers refer to the documentation supplied with your Intel Gigabit adapter.

To eliminate the potential for the hang ensure that RxIntDelay is set to zero. Drivers Update Tool Information. This has a possible negative performance impact, which may be compensated for by allocating more descriptors using the TxDescriptors module parameter.

This may differ for various Linux distributions. This is caused by the way the Linux kernel reports this stressed condition. 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.

Drivers found in our drivers database. These drivers are only supported as a loadable module. The parameter may be specified as either a decimal or hexadecimal value as determined by the bitmap below. Note The e driver is no longer maintained as a standalone component.

If the system is reporting dropped receives, this value may be set too high, causing the driver to run out of available receive descriptors. If the driver load fails to enable a specific interrupt mode, the driver will try other interrupt modes, from least to most compatible. The AutoNeg parameter is used when more control is required over the auto-negotiation process. This utility was recognized by many users all over the world as a modern, convenient alternative to manual updating of the drivers and also received a high rating from known computer publications.

Many popular Linux distributions ship with tools to make these changes for you. 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.

If you require a response, contact support. Multiqueue is off by default. This will impart the greatest chance for your system to consume less power. Three keywords are used to control the speed and duplex configuration.

Move the base driver tar file to the directory of your choice. This value specifies the number of receive buffer descriptors allocated by the driver.

Support Navigation Support. Refer to the Speed and Duplex section of this readme for more information on the AutoNeg parameter.

The default operation is auto-negotiate. To reduce the impact, the packet buffer sizes and relevant flow control settings are modified accordingly.

This value represents the size-order of each transmit descriptor. For this driver version, in order to enable WoL, the ee driver must be loaded prior to shutting down or suspending the system.

How many users the utility has helped to install the latest drivers? In this case, use a lower number. This information is accessed by the hardware.

It is most effective in an environment with many small transactions. TxDescriptors This value is the number of transmit descriptors allocated by the driver. This method allows you to save your time and correctly install all necessary drivers, not being afraid to make a mistake during a manual installation. Degradation in throughput performance may be observed in some Jumbo frames environments.

If both Duplex and the link partner are set to auto-negotiate, the board auto-detects the correct duplex. The user can turn off this parameter in supported chipsets. This value coincides with the maximum Jumbo Frames size of bytes. This may increase network latency but also increases the chances that the system will enter a lower power state.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team. What percent of users has not helped this article? Useful only if TxIntDelay is non-zero, this value ensures that an interrupt is generated after the initial packet is sent on the wire within the set amount of time. If such problems are encountered, you may disable the irqbalance daemon or upgrade to a newer kernel.
