Restarting the system appears to be the only remedy. Use the mediaopt option to select full-duplex mode. This issue is fixed in kernel version 2. Connecting the system to a switch or router will filter out most traffic not addressed to the local port. The igbvf driver supports based virtual function devices that can only be activated on kernels that support SR-IOV.

Increasing this value adds extra latency to frame reception and can end up decreasing the throughput of TCP traffic. This value coincides with the maximum Jumbo Frames size of LLISize causes an immediate interrupt if the board receives a packet smaller than the specified size.

After determining the type of incoming traffic in the last timeframe, it will adjust the InterruptThrottleRate to an appropriate value for that traffic. The default value is 0, since adapters may hang with this feature being enabled. It is most effective in an environment with many small transactions.

CONFIG_E1000: Intel(R) PRO/1000 Gigabit Ethernet support

After requesting interrupts for MSI-X vectors, system may panic. Connecting the system to a switch or router will filter out most traffic not addressed to the local port.

Please submit your comments, questions, or suggestions here. RxDescriptors This value specifies the number of receive buffer 82546ggb allocated by the driver. WoL will be enabled on the system during the next shut down or reboot.


Jumbo Frames support is enabled by changing the MTU to a value larger than the default of After installing the driver, if your Intel Network Connection is not working, verify that you have installed the correct driver. 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:.

The em driver supports the following media options: This enables the 82546g power saving feature. As the issue addressed by this parameter has never been observed on Intel Architecture platforms, inrel should not be used on Intel platforms. The install location listed above is the default location. In simplified mode the interrupt rate is based ontel the ratio of tx and rx traffic.

Some Intel itel adapters that support Jumbo Frames have a frame size limit of bytes, with a corresponding MTU size limit of bytes. The default value is The default value is for adapters newer thanand for older ones. Lithography refers to the semiconductor technology used to manufacture an integrated circuit, and is reported in nanometer nmindicative of the size of features built on the semiconductor. A receive buffer is also 82564gb for each descriptor and can be either,or bytes, depending on the MTU setting.


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.

Allows for delivery and returns. In addition, the controller is automatically reset, restoring the network connection. For more information on configuring this device, see ifconfig 8.

Link messages will not be displayed to the intfl if the distribution is restricting system messages. There are other conditions which may result in inrel Timeout”, which will not be resolved by the use of the TxDescriptorStep parameter. This parameter is not supported on the based adapter.

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 may increase network latency but also increases the chances that lonux system will enter a lower power state. There is a known hardware compatibility issue on some systems with RHEL3 kernels.

Using kernel versions earlier than 3.
