INSTALL IGB DRIVER
In this case, use a lower number. For questions related to hardware requirements, refer to the documentation supplied with your Intel Gigabit adapter. This enables the problematic power saving feature. This workaround skips resetting the Phy at shutdown for the initial silicon releases of ICH8 systems. Proper tuning, along with TxIntDelay, may improve traffic throughput in specific network conditions. It only needs to be set for Jumbo Frames. Install the ee driver using the instructions in the ee section.

Linux* Base Drivers for Intel® Ethernet Network Connection
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:. Increasing this value adds extra latency to frame reception and can end up decreasing the throughput of TCP traffic. 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:.
Alternatively, you can use ethtool version 1. This bug affects 1 person.
For questions related to hardware requirements, refer to the documentation supplied with your Intel Gigabit adapter. Using the latest intel driver the problem seems insatll be solved!!
All interrupts are throttled via interrupt moderation. TxDescriptors This value is the number of transmit descriptors allocated by the driver.

Channel Bonding documentation can be found in the Linux kernel source: If your version of e is 7. After installing the driver, if your Intel Network Connection is not working, verify that you have installed the correct driver. Home directory not accessible: Does this problem exist with vanilla upstream kernels? This script will verify that the adapter is applicable to the fix and if the fix is needed or not.
This may increase network latency but also increases the chances that the system will enter a lower power state. This value coincides with the maximum Jumbo Frames size of bytes.

Interrupt moderation must be used to avoid interrupt storms while the driver is processing one interrupt. Doing ijstall will cause your VFs to stop working until you reload the PF driver and may cause a spontaneous reboot of your system. The driver has two adaptive modes setting 1 or 3 in which it dynamically adjusts the InterruptThrottleRate value based on the traffic that it receives.
If you encounter the instxll in an adapter, and the chipset is an based one, you can verify that your adapter needs the fix by using ethtool: This change has been made by an automated script, maintained by the Ubuntu Kernel Team.
These drivers are only supported as a loadable module. Do not use MSI-X with the 2. Refer to the Speed and Duplex section of this readme for more information on the AutoNeg parameter. Instructions on updating ethtool can be found in the section Additional Configurations later in this document.
LLI allows for immediate generation of an interrupt upon processing receive packets that match certain criteria as set by the parameters described below. Brad Figg brad-figg wrote on Onstall tuning, along with TxIntDelay, may improve traffic throughput in specific network conditions.

If the link partner is forced to a specific speed and duplex, then this parameter should not be used. For situations where low latency is vital such as cluster or grid computing, the algorithm can reduce latency even more when InterruptThrottleRate is set to mode 1. The user can turn off this parameter in supported chipsets. This parameter is different than other parameters, in that it is a single not 1,1,1 etc.
Tested both kernels http: As this value decreases one may want to consider increasing the TxDescriptors value to maintain the same amount of frame memory. So there seems to be two working configurations now: Setting InterruptThrottleRate to a value greater or equal to will program the adapter to send out a maximum of that many interrupts per second, even if more packets have come in.
