No Link partner advertised auto-negotiation: Join our community today! The script can be downloaded at http: I would mention that the original poster on UbuntuForums — who has the same card as I do — reportedly tested this both on Hardy and Intrepid and states that the problem persists. I have a Gbit card in my Dell. This value represents the size-order of each transmit descriptor.

All hardware requirements listed apply to use with Linux. This default mode is suitable for most applications. MTU designates the frame size. I don’t know enough about it to understand what this means – I was untel flipping all switches until things started to work. Receive interrupt reduction can improve CPU efficiency if properly tuned for specific network traffic.

I have 2 of them Any help with this would be much appreciated Thanks. I have narrowed down the source of the problem.

High latency on Intel PI based Pro/ network card.

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. The driver utilizes the ethtool interface for driver configuration and diagnostics, as well as displaying statistical information.


To build igb driver with DCA: MSI-X is required for multiple queue support, and some kernels and combinations of kernel.

There are other conditions which may result in “TX Timeout”, which will not be resolved by the use of the TxDescriptorStep parameter. Replace the switch first lnux at least the cables.

Linux* Base Drivers for IntelĀ® Ethernet Network Connection

Then select the name of the specified base driver: When you boot with 2. This is caused by the way the Linux kernel reports this stressed condition. I have found a linux driver on Intel’s website, but before I go through all that, I want to make sure that it is necessary. Some Intel gigabit adapters that support Jumbo Frames have a frame size limit of bytes, with a corresponding MTU size limit of bytes.

I have ordered two more NICS to try in case this one just doesn’t work. Is there a way around this problem?

Linux Driver for IntelĀ® Gigabit Network Connections

Are you saying there is a known issue with the Intel cards as of a few months ago? For more information about the InterruptThrottleRate parameter, see the application note at: The maximum MTU size is If your version of e is 7. This issue won’t be seen on 32bit version of EL5, as in that case, the kernel sees that RAM is located around the MB window and avoids using the mmconfig lijux.


This value coincides with the maximum Jumbo Frames size of bytes.

CONFIG_E1000: Intel(R) PRO/1000 Gigabit Ethernet support

I wanted to add that I found some more information at: They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. Allocating Rx buffers when using Jumbo Frames on 2.

NAPI Rx polling mode is supported in the e driver. If it is not in the man pages or the how-to’s this is the place! In simplified mode the interrupt rate is based on limux ratio of tx and rx traffic. Add tags Tag help.

If you have a machine with a BMC enabled but cannot receive IPMI traffic after loading or enabling the driver, try disabling this feature. I also don’t have an easy way to stick this card in another machine all my other computers are Macs.
