In the beginning I thought this was a driver issue. Enabling LLIPush may allow a denial of service attack. In this mode, which operates the same as mode 3, the InterruptThrottleRate will be increased stepwise to for traffic in class “Lowest latency”. To override the default, use the following compile-time flags. Increasing this value adds extra latency to frame reception and can end up decreasing the throughput of TCP traffic. Load the module using either the insmod or modprobe command:

In order to see network driver link messages on your console, set dmesg to eight by entering the following:. Node 0-n 0 – n: This I have to repeat at every kernel update, since kernel updates still 3. As an example, if you install the igb 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. This issue is fixed in kernel version inyel.
The script can be downloaded at http: All hardware requirements listed apply to use with Linux. Daniel Eckert 31 1 1 4.
Linux Driver for Intel® Gigabit Network Connections
Other distributions may store this setting in a different location. The Linux base drivers support the 2. For this driver version, in order to enable WoL, the e driver must be loaded prior to shutting down or suspending the system. This example applies to the Red Hat distributions; other distributions may store this setting in a different location. This driver supports multiqueue in kernel versions 2.
LRO combines multiple Ethernet frames into a single receive in the stack, thereby potentially decreasing CPU utilization for receives. On certain non-Intel e00e, it has been observed that intense Inteo traffic bursts of short packets may result in an improper descriptor writeback.
Setting InterruptThrottleRate to 0 turns off any interrupt moderation and may improve small packet latency, but is generally not suitable for bulk throughput traffic NOTE: Increasing this value adds extra latency to frame reception and can end up decreasing the throughput of TCP traffic. Build error with Asianux 3. As an example, if you install the e driver for two Gigabit adapters eth0 and eth1 and set the speed and duplex to 10full and half, add the following to modules.
I wanted to install the newest version of the ee driver. Forcing master or forcing slave mode will improve time-to-link.
Alternatively, you can use ethtool version 1. Please do not enter contact information. A descriptor describes a data buffer and attributes related to the data buffer. Leave a Reply Cancel reply Your email address will not be published.
Allows changing the interrupt mode at module load time, without requiring a recompile. The virtual machine will see a 10 Gbit virtual NIC attached to a virtual switch inside the host, but the VM will never see the physical interfaces which could be of any speed. Interrupt moderation must be used to avoid interrupt storms while the driver is processing one interrupt.
Channel Bonding documentation can be found in the Linux kernel source: If you require a response, contact support. This issue may be seen with PCI-X adapters or with packet split disabled. In addition the number of queues available for RSS is limited if this is set to 1 or greater. The e driver is no longer maintained as a standalone component. The igbvf driver requires the igb driver, version 2. The parameter may be specified as either a decimal or hexadecimal value as determined by the bitmap below.
As this value decreases one may want to consider increasing the TxDescriptors value to maintain the same amount of frame memory. How paravirtualized network work when there is no Physical Adapter.
