Intel 825xx Gigabit Platform Lan Network Device Linux Driver

Verify that the interface works. This value specifies the number of receive buffer descriptors allocated by the driver. Increasing this value allows the driver to buffer more incoming packets, at the expense of increased system memory utilization. The default operation is auto-negotiate. Once the class is determined, the InterruptThrottleRate value is adjusted to suit that traffic type the best.

In passing they mentioned that maybe there was an issue with the network adapter itself or with its plug that connect it to the mainboard. 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. To learn the proper way to configure a network device for your system, refer to your distribution documentation. Many popular Linux distributions ship with tools to make these changes for you.

In simplified mode the interrupt rate is based on the ratio of tx and rx traffic. If you do not want to install the other ones that is fine. Refer to the Speed and Duplex section of this readme for more information on the AutoNeg parameter. The e driver is no longer maintained as a standalone component.

Forcing master or forcing slave mode will improve time-to-link. Can be either one or two-directional. To override the default, use the following compile-time flags.

Interrupt moderation must be used to avoid interrupt storms while the driver is processing one interrupt. If both Duplex and the link partner are set to auto-negotiate, the board auto-detects the correct duplex. It is most effective in an environment with many small transactions. Multiqueue is off by default. This parameter is supported only on adapters using copper connections.

The hardware can handle many more small packets per second however, and for this reason an adaptive interrupt moderation algorithm was implemented. RxDescriptors This value specifies the number of receive buffer descriptors allocated by the driver. If you require a response, contact support. Home Questions Tags Users Unanswered. These keywords are Speed, Duplex, and AutoNeg.

This may differ for various Linux distributions. All hardware requirements listed apply to use with Linux. Normally the driver will generate an interrupt every two seconds.

Increasing this value allows the driver to queue more transmits. Depending on the available system resources, the request for a higher number of receive descriptors may be denied. In this case, use a lower number.

There is a known issue using Jumbo frames when connected to a Foundry BigIron switch. Allows Phy to turn off in lower power states. If the link partner is forced to a specific speed and duplex, then this parameter should not be used. To reduce the impact, the packet buffer sizes and relevant flow control settings are modified accordingly.

This setting is not saved across reboots. TxDescriptors This value is the number of transmit descriptors allocated by the driver. This information is accessed by the hardware.

Intel is not supplying patches against the kernel source to allow for static linking of the driver. For questions related to hardware requirements, refer to the documentation supplied with your Intel Gigabit adapter. After installing the driver, if your Intel Network Connection is not working, verify that you have installed the correct driver. If during this process you are asked for the driver or module name, amd radeon 6500m drivers the name for the Linux Base Driver for the Gigabit family of adapters is ee.

For this driver version, in order to enable WoL, the e driver must be loaded prior to shutting down or suspending the system. All interrupts are throttled via interrupt moderation. For this driver version, in order to enable WoL, the ee driver must be loaded prior to shutting down or suspending the system. This driver is only supported as a loadable module at this time. Other distributions may store this setting in a different location.

Linux Base Drivers for Intel Ethernet Network Connection

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. The user can turn off this parameter in supported chipsets. Otherwise the driver can be loaded once and will be safe, but unloading it will lead to the issue. This value is the number of transmit descriptors allocated by the driver.

Restarting the system appears to be the only remedy. This value represents the size-order of each transmit descriptor. This default mode is suitable for most applications.

Configuring a network driver to load properly when the system is started is distribution dependent. Proper tuning, along with TxIntDelay, may improve traffic throughput in specific network conditions.

Linux Base Drivers for Intel Ethernet Network Connection

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. The range of to interrupts per second works on a majority of systems and is a good starting point, but the optimal value will be platform-specific. As the issue addressed by this parameter has never been observed on Intel Architecture platforms, it should not be used on Intel platforms.

In addition, the controller is automatically reset, restoring the network connection. If such problems are encountered, you may disable the irqbalance daemon or upgrade to a newer kernel. This parameter is not supported on the based adapter.

If the system is reporting dropped transmits, this value may be set too high causing the driver to run out of available transmit descriptors. However, the frequency and random intervals at which packets arrive do not allow the system to enter a lower power state. This has a possible negative performance impact, which may be compensated for by allocating more descriptors using the TxDescriptors module parameter. The AutoNeg parameter is used when more control is required over the auto-negotiation process.
