If you encounter the problem in an adapter, and the chipset is an based one, you can verify that your adapter needs the fix by using ethtool: If you encounter the problem in an adapter, and the chipset is an based one, you can verify that your adapter needs the fix by using ethtool:. Install the ee driver using the instructions in the ee section. This driver supports multiqueue in kernel versions 2. A receive buffer is also allocated for each descriptor and can be either , , , or bytes, depending on the MTU setting. Using Jumbo frames at 10 or Mbps is not supported and may result in poor performance or loss of link.

Linjx is a known issue using Jumbo frames when connected to a Foundry BigIron switch. Transmit interrupt reduction can improve CPU efficiency if properly tuned for specific network traffic. This will impart the greatest chance for your system to consume less power. IntMode controls allow load time control over the type of interrupt registered for by the driver. DMA Coalescing is effective in helping potentially saving the platform power only when it is 8256gb across all active ports.
The moderation value should be at least as large as the expected time for the driver to process an interrupt. The default behaviour of the driver previously assumed a static InterruptThrottleRate value ofproviding a good fallback value for all traffic types, but lacking in small packet performance and latency. If the driver is built as a module, the following optional parameters are used by entering them on the command line with the modprobe command using this syntax:.
RPM functionality has only been tested in Red Hat distributions. Depending on the available system resources, the request for a higher number of receive descriptors may be denied. The default value for each parameter is generally the recommended setting, unless otherwise noted. The default value is for adapters newer thanand for older ones.
After installing the driver, if your Intel Ethernet Network Connection is not working, verify that you have installed the correct driver.

Command Line Parameters If the driver is built as a module, the following optional parameters are used by entering them on the command line with the modprobe command using this syntax:. Your comments have been sent. On some kernels a reboot is required to switch between a single queue mode and multiqueue modes, or vice-versa.
This has a possible negative performance impact, which may be compensated for by allocating more descriptors using the TxDescriptors module parameter.
This parameter is different than other parameters, in that it is a single not 1,1,1 etc. 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 8254gb respectively, add the following to modules.
Load the module using either kinux insmod or modprobe command: MSI-X is required for multiple queue support, and some kernels and combinations of kernel. For this driver version, in order to enable WoL, the ee driver must be loaded prior to shutting down or suspending the system. To build igb driver with DCA: If a system based on the, or controller is connected to a hub, the Activity LED will blink for all network traffic present on the hub. If the link partner is forced either full or halfDuplex defaults to half-duplex.
After installing the driver, if your Intel Network Connection is not working, verify that you have installed the correct driver. The driver can limit the amount of interrupts per second that the adapter will generate for incoming packets.

The default operation is auto-negotiate. There are no workarounds for this problem in this network configuration. The default value is In addition the number of queues available for RSS is limited if this is set to 1 inrel greater. In simplified mode the interrupt rate is based on the ratio of tx and rx traffic. In order to see network driver link messages on your console, set dmesg to eight by entering the following:.
Defines the direction in which data is allowed to flow. If you have multiple interfaces in a server, either turn on ARP filtering by entering:.
