This has a possible negative performance impact, which may be compensated for by allocating more descriptors using the TxDescriptors module parameter. 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. This example applies to the Red Hat distributions; other distributions may store this setting in a different location. Other bug subscribers Subscribe someone else. Martin Pitt pitti on

firmware-linux-free: Packet loss after Upgrade (Intel )

intel 82576 linux Adapters that have 4 ports behind a PCIe bridge may be incompatible with some systems. It does this by writing a value to the adapter that is based on the maximum amount of interrupts that the adapter will generate per second.

When setting RxIntDelay to a value other than 0, adapters may hang stop transmitting under certain network conditions. Please include this in 8.

This driver is only supported as a loadable module at this time. DMA Coalescing is effective in helping potentially saving the platform power only when it is enabled across all active ports. However, enable the propose, using the. If such problems are encountered, you may disable the irqbalance daemon or upgrade to a newer kernel. When this intel 82576 linux is used, the Speed and Duplex parameters must not be specified.

Stefan Bader smb wrote on Michael Shadle mshadle intel 82576 linux on This value delays the generation of receive interrupts in units of 1. If this occurs, the driver will report a “TX Timeout” and reset the adapter, after which the transmit flow will restart, though intel 82576 linux may have stalled for as much as 10 seconds before it resumes.

intl Email me intel 82576 linux changes to this bug report. Proper tuning, along with RxIntDelay, may improve traffic throughput in oinux network conditions. On certain non-Intel architectures, intel 82576 linux has been observed that intense TX traffic bursts of short packets may result in an improper descriptor writeback. I manually packed the module dca from linux-image- 2.

Accepted linux-ubuntu- modules- 2. Instructions on updating ethtool can be found in the section Additional Configurations later in this document.

Check out Ubuntu’s documentation on building the installation medias. The default value for each parameter is generally the recommended setting, unless otherwise intel 82576 linux.

This is caused by the way the Linux kernel reports this stressed condition. Please intel 82576 linux and give feedback here. Kernel panics and instability may be observed on any MSI-X hardware if you use irqbalance with kernels between 2. Use the ifconfig command to increase the MTU size.

As an example, if you install the ee 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.

If the system is reporting dropped transmits, this value may be set too high causing the driver to run out of available transmit descriptors. If the system is reporting dropped receives, this value may be set too high, causing the linix to run out of available receive descriptors. Multiqueue In this mode, intel 82576 linux separate MSI-X vector is allocated for each queue and one for “other” interrupts such as link status change and errors.
