For questions related to hardware requirements, refer to the documentation supplied with your Intel Gigabit adapter. In addition the number of queues available for RSS is limited if this is set to 1 or greater. On some kernels a reboot is required to switch between a single queue mode and multiqueue modes, or vice-versa. On certain non-Intel architectures, it has been observed that intense TX traffic bursts of short packets may result in an improper descriptor writeback. If you have a machine with a BMC enabled but cannot receive IPMI traffic after loading or enabling the driver, try disabling this feature.

In this mode, which operates the same as mode 3, the InterruptThrottleRate will be increased stepwise to for traffic in class “Lowest latency”.
Connecting the system to a switch or router will filter out most traffic not addressed to the local port. The default operation is auto-negotiate. EEE saves energy by putting the device into a low-power state when the link is idle, but only when the link partner also intel 82580 linux EEE and intel 82580 linux the feature has been enabled during link negotiation.

MSI-X is intel 82580 linux for multiple queue support, and some kernels and combinations of kernel. For other Linux distributions, download and install ethtool from the following website: A1 Yes, the EB is implemented on our design. Turning on DMA Coalescing may save energy with lntel 2. If this occurs, the itel will report a “TX Intel 82580 linux and reset the adapter, after which the transmit flow will restart, though data may have stalled for as much as 10 seconds before it resumes.
LLI parameters are not enabled when Legacy interrupts are used. First identify your adapter. This is caused by the way the Linux kernel reports this stressed condition.
As an example, if you install the intel 82580 linux driver for two Gigabit adapters eth0 and eth1 and want to set inntel interrupt mode to MSI-X and MSI respectively, add the following to modules.

This program can confuse your I2C bus, cause data loss and worse! To override the default, use the following compile-time flags.
These drivers are only supported as a loadable module. To learn intel 82580 linux proper way 82508 configure a network device for your system, refer to your distribution documentation. To reduce the impact, the packet buffer sizes and relevant flow control settings are modified accordingly.
Increasing this value adds extra latency to frame reception and can end up decreasing the throughput of TCP traffic. LLISize causes an immediate interrupt if the board receives a packet smaller than the specified size.
The igbvf driver supports based virtual function devices that can only be activated on kernels that support Intel 82580 linux.
Intel 82580 linux questions related to hardware requirements, refer to the documentation supplied with your Intel Gigabit adapter. It should be used when you wish to control which speed and duplex combinations are advertised during the auto-negotiation process.

After requesting interrupts for MSI-X vectors, system may ilnux. A3 I acquired it on https: The default behaviour of the driver previously assumed a static InterruptThrottleRate value ofproviding a good fallback value for all traffic types, but lacking in small packet performance and latency.
When igbvf is loaded with default settings and multiple adapters are in use simultaneously, the Intel 82580 linux utilization may increase non-linearly.
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. Forcing master or forcing slave mode will improve time-to-link. Based on your previous communication, you should address as a reference your consultations related to this driver to the support for Intel Ethernet Drivers and Utilities at its developer website.
The configuration change can be made permanent by adding the line: This setting is iintel saved across reboots. Move the base driver tar file to the directory of intel 82580 linux choice. This information is accessed by the hardware. This value, in units of 1. Linuux content has been marked as final. The igbvf inte, requires intel 82580 linux igb driver, version 2.
