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 e 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 space. The install location listed above is the default location. MSI-X is required for multiple queue support, and some kernels and combinations of kernel. Changed in linux Ubuntu Utopic: Proper tuning, along with RxIntDelay, may improve traffic throughput in specific network conditions.

If you encounter the problem in an adapter, and the chipset is an based one, you can verify that your iggb needs the fix by using ethtool:. Multiqueue In this mode, a separate MSI-X vector is allocated for each queue and one for “other” interrupts such as link status change and errors.
This results in unbalanced receive traffic.
The value at offset 0xe de has bit 0 unset. Changed in linux Ubuntu: This may differ for various Linux distributions. A descriptor describes a data buffer and attributes related to the data buffer.
If you currently have the e driver installed and need to install ee, perform the following: For more information about the InterruptThrottleRate parameter, see the application note at: This value delays the generation of transmit interrupts in units of 1. In order to limit the CPU utilization without impacting the overall throughput, we recommend that you load the driver as follows: Then select the name of the specified base driver: Tested both kernels http: Please send me a link where I can download 3.
When setting RxIntDelay to a value other than 0, adapters may hang stop transmitting under certain network conditions. The boot issue seems to be fixed but the driver has a lot more issues as described in post 21 please “download the full text” because the posted version looks a little bit confusing. We’ve installed windows r2 on the same server to be sure not having a potential hardware problem -!!
EEE support requires autonegotiation. If your version of e is 7. 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 e This will impart the greatest chance for your system to consume less power.
This is a 3rd party limitation.
How to install new ethernet adaptor driver in old kernel. – Porteus
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. For this driver version, in order to enable WoL, instal, e driver must be loaded prior to shutting down or suspending the system. This value is the number of transmit descriptors allocated by the driver.
You need to log in to change this bug’s status. Ports 1 and 2 don’t show any errors and will pass traffic. The Linux base drivers support the 2.
The driver utilizes the ethtool interface for driver configuration and diagnostics, as well as displaying statistical information.
On certain non-Intel architectures, it has been observed that intense TX traffic bursts of short packets may result in an improper descriptor writeback. There is a known issue using Jumbo frames when connected to a Foundry BigIron switch. Turning on DMA Coalescing may save energy with kernel 2. As this isntall decreases one may want to consider increasing the TxDescriptors value to maintain the same amount of frame memory.
Linux* Base Drivers for Intel® Ethernet Network Connection
This has a possible negative performance impact, which may be compensated for isntall allocating more descriptors using the TxDescriptors module parameter.
If traffic falls in the “Low latency” or “Lowest latency” class, the InterruptThrottleRate is increased stepwise to After installing the driver, if your Intel Ethernet Network Connection is not working, verify that you have installed the correct driver.
