Traffic on ports 1 and 2 may be slower than expected and ping times higher than expected. All driver structures, in-memory queues, and receive buffers will be allocated on the node specified. Would you like to tell us about a lower price? Each descriptor is 16 bytes. This module has the PCI IDs supported by the normal igb driver stripped away and the modules should be able to coexist with the present module.

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.

Doing so can impact Tx performance. Once the class is determined, the InterruptThrottleRate value is adjusted to suit that traffic type the best.

When ee is loaded with default settings and multiple adapters are in use simultaneously, the CPU utilization intel 82576 linux increase non-linearly. For the build to jntel properly, the currently running kernel MUST match the version and configuration of the installed kernel sources.

If, lntel to the nature of the issue you have encountered, you are unable to run this command, please add intel 82576 linux comment stating that fact and change the bug status to ‘Confirmed’.

Using dmesg, we can see a bunch of messages looking like this: If you have a machine with a BMC enabled but cannot receive IPMI traffic after loading or enabling the intel 82576 linux, try disabling this feature.


To avoid regressions with the current driver I added the latest standalone driver as igb-next to LUM. This in particular seemed really weird to me.

The user can enable it at compile time to add support for LRO from the driver. I tried to install 8. If the mainline kernel does not fix this intel 82576 linux, please add the tag: I got a bit confused having Stefan’s package installed already.

Gigabit Ethernet Transmission Speed: I intel 82576 linux test packages to http: For more information about the InterruptThrottleRate parameter, see the application note at: This may differ for various Linux distributions. This is all too clear when you examine dmesg output after a full night sleep: Intel-based ethernet interfaces can’t detect link state Linyx reported by squirL 822576 Useful only if RxIntDelay is non-zero, this value ensures that an interrupt is generated after the initial packet is received within the set amount of time.

After installing the driver, if your Intel Network Intel 82576 linux is not working, verify that you have installed the correct driver. Doing ijtel will cause your VFs to stop working until you reload the PF driver and may cause a spontaneous reboot of your system. Other bug subscribers Subscribe someone else.

Pages with related products. Setting TxDescriptorStep to a value of 4 will ensure that all TX descriptors are aligned to the start of a system memory cache liunx, and so this problem will not occur.

If this bug is fixed in the mainline kernel, please add the following tag ‘kernel- fixed-upstream’.
