When ee is loaded with default settings and multiple adapters are in use simultaneously, the CPU utilization may increase non-linearly. To override the default, use the following compile-time flags. If traffic falls in the “Low latency” or “Lowest latency” class, the InterruptThrottleRate is increased stepwise to Many popular Linux distributions ship with tools to make these changes for you. LLI allows for immediate generation of an interrupt upon processing receive packets that match certain criteria as set by the parameters described below.

Instructions on updating ethtool can be found in the section Additional Configurations later in this document. As an example, if you install the igbvf driver for two Gigabit adapters eth0 and eth1 and want to set the interrupt mode to MSI-X and MSI respectively, add the following to modules.

Sign up using Email and Password. If you require a response, contact support. Intdl option can be overridden to 1 if there are not sufficient interrupts available. Overview The Linux base drivers support the 2. For questions related to hardware requirements, see the documentation supplied with your Intel Gigabit adapter.

Alternatively, you can use ethtool version 1. Firstly, what confuses me is that four entrances are shown, and the system shows eth0 – eth3 four portseven though the NIC only has two ports in the specs. Load the module using either the insmod or modprobe command: 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.

Linux* Base Virtual Function Driver for Intel(R) 1G Ethernet — The Linux Kernel documentation

It does this by writing a value to corporayion adapter that is based on the maximum amount of interrupts that the adapter will generate per second.

EEE saves energy by putting the device into a low-power state when the link is idle, but linhx when the link partner also supports EEE and after the feature has been enabled during link negotiation. There is a known issue using Jumbo frames when connected to a Foundry BigIron switch.

LLI parameters are not enabled when Legacy interrupts are used.

Linux* Base Driver for Intel® Gigabit Ethernet Network Connections

Restarting the system appears to be the only remedy. When ee is loaded with default settings and multiple adapters are in use simultaneously, the CPU utilization may increase non-linearly. Server Fault works best with JavaScript enabled.

In addition, the controller is automatically reset, restoring the network connection. Proper tuning, along with TxIntDelay, may improve traffic throughput in specific network conditions.

Linux Kernel Driver DataBase: CONFIG_IGB: Intel(R) / PCI-Express Gigabit Ethernet support

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. In order to limit the CPU utilization without impacting the overall throughput, we recommend that you load the driver as follows: Channel Bonding documentation can be found in the Linux kernel source: To build igb driver with DCA: If a system based on the, or controller is connected to a hub, the Activity LED will blink for all network traffic present on the hub.

The moderation value should be at least as large as the expected time for the driver to process an interrupt. This value coincides with the maximum Jumbo Frames size of Setting TxDescriptorStep to a value of 4 will ensure that all TX descriptors are aligned to the start of a system memory cache line, and so this problem will not occur.

The user should run the Linux firmware kit from http: Spooler 5, 9 The improper writeback does not occur on the first descriptor in a system memory cache-line, which is typically 32 bytes, or 4 descriptors long.

To eliminate the 82567 for the hang, ensure that InterruptThrottleRate is set no greater than 75, and is not set to 0. Degradation in throughput performance may be observed in some Jumbo frames environments.

Otherwise the driver can be loaded once and will be safe, but unloading it will lead to the issue.
