Using kernel versions earlier than 3. Depending on the available system resources, the request for a higher number of receive descriptors may be denied. Command Line Parameters If the driver is built as a module, the following optional parameters are used by entering them on the command line with the modprobe command using this syntax:. If you are required to use a 2. LRO combines multiple Ethernet frames into a single receive in the stack, thereby potentially decreasing CPU utilization for receives.

Increasing this value allows the driver to buffer more incoming packets, at the expense of increased system memory utilization. Receive interrupt reduction can improve CPU efficiency if properly tuned for specific network traffic. This may differ for various Linux distributions.

Package Find… Status Importance Invalid. If the traffic is mostly transmit or mostly receive, the interrupt rate could be as high as The moderation value should be at least as large as the expected time for the driver to process an interrupt. Launchpad Janitor janitor wrote on Install the ee driver using the instructions in the ee section.

If the link partner is forced to a specific speed and duplex, then this parameter should not be used. Move the base driver tar file to the directory of your choice.


This driver supports receive multiqueue on all kernels that support MSI-X. EEE 1 enabled 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.

Can be either one or two-directional. The following adapters limit Jumbo Frames sized packets to a maximum of bytes: This parameter is different than other parameters, in that it is a single not 1,1,1 etc. Auto-negotiation is disabled, and the AutoNeg parameter is ignored.

From a terminal window please run: If you currently have the e driver installed and need to install ee, perform the following: Instead, use the Speed and Duplex parameters previously mentioned to force the adapter to the same speed ibb duplex.

TxDescriptors This value is the number of transmit descriptors allocated by the driver. Marking invalid since the issue does not appear to be related to the driver. Each descriptor is 16 bytes.

Defines the direction ig which data is allowed to flow. This driver supports multiqueue in kernel versions 2. Additional Configurations Configuring the Driver on Different Distributions Configuring a network driver to load properly when the system is started is distribution dependent.

In simplified mode the interrupt rate is based on the ratio of tx and rx traffic.

For this driver version, in order to enable WoL, the e driver must be loaded prior to shutting down or suspending the system. If both Duplex and the link partner are set to auto-negotiate, the board auto-detects the correct duplex.

Then follow the appropriate steps for building, installing, and configuring the driver. The maximum MTU size is This script will verify that the adapter is applicable to the fix and if the fix is needed or not. 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. Than we changed the switch.

Linux Driver for Intel® Gigabit Network Connections

Kernel panics and instability may be observed on any MSI-X hardware if you use irqbalance with kernels between 2. Several adapters with the chipset display “TX unit hang” messages during normal operation with the e driver.

Tested both kernels http: In this mode, which operates the same as mode 3, the InterruptThrottleRate will be increased stepwise to for traffic in class “Lowest latency”.
