All hardware requirements listed apply to use with Linux. That didn’t fix the problem either and resulted in the following warning message when booting: Adapters that have 4 ports behind a PCIe bridge may be incompatible with some systems. Allocating Rx buffers when using Jumbo Frames on 2. The default operation is auto-negotiate.

Refer to the Speed and Duplex section of this readme for more information on the AutoNeg parameter. When intep spoofed packet is detected the PF driver will send the intel 80003es2lan message to the system log intel 80003es2lan by the “dmesg” command:.

The following adapters limit Jumbo Frames sized packets to a maximum of bytes: Multiqueue In this mode, a separate MSI-X intel 80003es2lan is allocated for each queue and one for “other” interrupts such as link status change and errors. The script can be downloaded at 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: Adapters that have 4 ports behind a Intel 80003es2lan bridge may be incompatible with some systems.

Linux* e1000 Base Driver Overview and Installation

NAPI is enabled or disabled based on the configuration of the kernel. This parameter is supported only onand later adapters. We recommend the newer intep. Multiqueue is off by default. For other Linux distributions, download and install ethtool intel 80003es2lan the following website: Using kernel versions earlier than 3. On some kernels a reboot is required to switch between a single queue intel 80003es2lan and multiqueue modes, or vice-versa.

The hardware can handle many intel 80003es2lan small packets per second however, and for this reason an adaptive interrupt moderation algorithm intel 80003es2lan implemented. Using Jumbo frames at 10 or Mbps is not supported and may result in poor performance or loss of link.

All hardware 80003ex2lan intel 80003es2lan apply to use with Linux. Link messages will not be displayed to the console if the distribution is restricting system messages.

As an example, if you install the igb driver for two Gigabit adapters eth0 and eth1 inte want to set the interrupt mode to MSI-X and MSI respectively, add the following intel 80003es2lan modules. The driver can limit the amount of interrupts per second that the adapter will generate for incoming packets. There are other conditions which may result in “TX Timeout”, which will not be resolved by the 80003ws2lan of the TxDescriptorStep parameter.

When a malicious driver attempts to send a spoofed packet, it is dropped intel 80003es2lan the hardware and not transmitted. Due to intel 80003es2lan support for PCI-Express in 2. I also found an URL that talks about this problem: Instead, intel 80003es2lan the Speed and Duplex parameters previously mentioned to force the adapter to the same speed and duplex. This parameter is different intel 80003es2lan other parameters, in 80003es2ln it is a single not 1,1,1 etc.

As an example, if you install the e driver for two Gigabit adapters eth0 and eth1 and set intell intel 80003es2lan and duplex to 10full and half, add the following to modules.

For questions related to hardware requirements, refer to the documentation supplied with your Intel Intel 80003es2lan adapter. Try using modprobe directly: It only needs to be set for Jumbo Frames. Then follow the appropriate steps for building, installing, and configuring the driver.

Intel® Gigabit Ethernet Controller Family: Technical Library

Interrupt moderation must be used to avoid interrupt storms while the driver is processing one interrupt. Other distributions may intel 80003es2lan this setting in a different location.

With some Phy and switch combinations, link can take intel 80003es2lan than expected.

There are three classes defined: Turning on DMA Coalescing may save energy with kernel 2.
