DMA Coalescing is effective in helping potentially saving the platform power only when it is enabled across all active ports. The hardware can handle many more small packets per second however, and for this reason an adaptive interrupt moderation algorithm was implemented. LRO combines multiple Ethernet frames into a single receive in the stack, thereby potentially decreasing CPU utilization for receives. October 7th, 2. If during this process you are asked for the driver or module name, the name for the Linux Base Driver for the Gigabit Family of Adapters is igbvf.

I’m not sure how else to troubleshoot this myself — unless I find something more on the internet to guide me, I am be stuck! Several adapters with the chipset display “TX unit hang” messages during normal operation with the e driver. The time now is This is caused by the way the Linux kernel reports this stressed condition. This value delays the generation of transmit interrupts in units of 1. I removed it because it shouldn’t have been there.

On some kernels a reboot is required to switch between a single queue mode and multiqueue modes, or vice-versa. The errors on this NIC are: Many popular Linux distributions ship with tools to make these changes for you.


Linux Driver for IntelĀ® Gigabit Network Connections

For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration.

See full activity log. 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 following to modules. This setting is not saved across reboots. Jeff Van Epps lordbah wrote 822541pi Linux – Newbie This Linux forum is for members that are new to Linux. 82541oi

The user should run the Linux firmware kit from http: If both Duplex and the link partner are set to auto-negotiate, the board auto-detects the correct duplex. However, on the back of the card, the yellow 1Gbit light is lit.

Lunux rebooted several times now and it seems like everything is all working. Kernel panics and instability may be observed on any MSI-X hardware if you use irqbalance with kernels between 2. Once the class is determined, the InterruptThrottleRate value is adjusted to suit that traffic type the best.

This parameter is not supported on the based adapter. On certain non-Intel architectures, it has been observed that intense TX traffic bursts of short packets may result in an improper descriptor writeback. Take everything out of except the cable. Am I missing a step somewhere? 85241pi cards are some of the better choices.


A whitepaper containing information on how to best configure your platform is available on the Intel website.

It wouldn’t recognize a video card I installed either. The default operation is auto-negotiate.

I was assuming that the new card was eth1, but it was in fact eth2. Connecting the system to a switch or router will filter out most traffic not addressed to the local port.

Alternatively, you can use ethtool version 1. For this driver version, in order to enable WoL, the ee driver must be loaded prior to shutting down or suspending the system. For the build to work properly, the currently running kernel MUST match the version and configuration of the installed kernel sources.
