The user should run the Linux firmware kit from http: 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: 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. Due to the default ARP behavior on Linux, it is not possible to have one system on two IP networks in the same Ethernet broadcast domain non-partitioned switch behave as expected. Multiqueue is off by default.

Enabling LLIPush may allow a denial of service attack. The value at offset 0xe 80003ed2lan has bit 0 unset. The default value for each parameter is generally the recommended setting, unless otherwise noted.
Copyright c – Intel Corporation. Useful only if TxIntDelay is non-zero, this value ensures that an interrupt is generated after the initial packet is sent on the wire within the set amount of time.

Other bug subscribers Subscribe someone else. I do not have access to my laptop right now, when I get it back I will look into it on a live linx. The default behavior of the driver previously assumed a static InterruptThrottleRate value of 80003es2ln, providing a good fallback value for all traffic types, but lacking in small packet performance and latency.
Find More Posts by Ser Olmy. Normally the driver generates an interrupt every two seconds.
This parameter is a bit mask that specifies which speed and duplex settings the board advertises. Transmit interrupt reduction can improve CPU efficiency if properly tuned for specific network traffic. LLIPush can be set to be enabled or disabled default. 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 infel this problem will not occur.
First identify your adapter. This will impart the greatest chance for your system to consume less power. A descriptor describes a data buffer and attributes related to the data buffer.
Increasing this 80003s2lan adds extra latency to frame reception and can end up decreasing the throughput of TCP traffic.
Using kernel versions earlier than 3. If you currently have the e driver installed and need to install ee, perform the following:.
This value coincides with the maximum Jumbo Frames size of 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 80003es2la to modules. The default operation is auto-negotiate. Setting InterruptThrottleRate inrel 0 turns off any interrupt moderation and may improve small packet latency, but is generally not suitable for bulk throughput traffic.
This may increase network latency but also increases the chances that the system will enter a lower power state. Intel is not supplying patches against the kernel source to allow for static linking of the driver.
To solve this issue, create the version. When this parameter is used, the Speed and Duplex parameters must not be specified. It is most effective in an environment with many small transactions. The version is too old, 2. intle

This is a 3rd party limitation. You are currently viewing LQ as a imtel. Install the ee driver using the instructions in the ee section. Last version is 3.
Many popular Linux distributions ship with tools to make these changes for you.
