This is caused by the way the Linux kernel reports this stressed condition. Allocating Rx buffers when using Jumbo Frames on 2. We recommend the newer 2. If you experience loss of packets, lower the MTU size. However, the frequency and random intervals at which packets arrive do not allow the system to enter a lower power state. This issue is fixed in kernel version 2.

Load the module using either the insmod or modprobe command: Using kernel versions earlier than 3. NAPI Rx polling mode is supported in the e driver. WoL will be enabled on the system during the next shut down or reboot. Some Intel gigabit adapters that support Jumbo Frames have a frame size limit of bytes, with a corresponding MTU size limit of bytes.
IntMode controls allow load time control over the type of interrupt registered for by the driver. The driver utilizes the ethtool interface for driver configuration and diagnostics, as well as displaying statistical information. As the issue addressed by this parameter has never been observed on Intel Architecture platforms, it should not be used on Intel platforms. Alternatively, you can use ethtool version 1.
For this driver version, in order to enable WoL, the ee driver must be loaded prior to shutting down or suspending the system.
Each descriptor is 16 bytes.

There are other conditions which may result in “TX Timeout”, which will not be resolved by the use of the TxDescriptorStep parameter. For questions related to hardware requirements, refer to the documentation supplied with your Intel Gigabit adapter.
Configuring a network driver to load properly when the system is started is linnux dependent. LLI allows for immediate generation of an interrupt upon processing receive packets that match certain ifb as set by the parameters described below. 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:. This can be an issue on Linux distributions that timeout when checking for link prior to acquiring a DHCP address; however there is usually a way to work around this e.
This default limux is suitable for most applications. For more information about the InterruptThrottleRate parameter, see the application note at: Example output of the script: Then select the name of the specified base driver: Receive interrupt reduction can improve CPU efficiency if properly tuned for specific network traffic.
When setting RxIntDelay to a value other than 0, adapters may hang stop transmitting under certain network conditions.

A receive buffer is also allocated for each descriptor and can be either,or bytes, depending on the MTU setting. First identify your adapter. Additional Ljnux Configuring the Driver on Different Distributions Lknux a network driver to load properly when the system is started is distribution dependent.
EEE support requires autonegotiation. The user should run the Linux firmware kit from http: Do not use MSI-X with the 2.
TxDescriptors This value is the number of transmit descriptors allocated by the driver. This is caused by the way the Linux kernel reports this stressed condition.

There is a known hardware compatibility issue on some systems with RHEL3 kernels. Build error with Asianux 3. However, the frequency and random intervals at which packets arrive do not allow the system to enter a lower power kgb.
Enabling LLIPush may allow a denial of service attack. This value, in units of 1. Once the class is determined, the InterruptThrottleRate value is adjusted to suit that traffic type the best.
