IGBVF LINUX DRIVER

In order to disable receive flow control using ethtool, you must turn off auto-negotiation on the same command line. WoL will be enabled on the system during the next shut down or reboot. Enabling LLIPush may allow a denial of service attack. On some kernels a reboot is required to switch between a single queue mode and multiqueue modes, or vice-versa. Adapters that have 4 ports behind a PCIe bridge may be incompatible with some systems.

Interrupt moderation must be used to avoid interrupt storms while the driver is processing one interrupt.

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. Due to the default ARP behavior on Jgbvf, it is not possible to have one system on two IP networks in the same Ethernet broadcast domain non-partitioned switch behave as expected.

In addition, the controller is automatically reset, restoring the network connection. The algorithm classifies llinux incoming traffic every interval into classes. This option allows for the ability of IEEE This value, in units of 1. This information is accessed by the hardware.

The moderation value should be at least as large as the expected time for the driver to process an interrupt.

If the bytes per second rate is approximately equal, the interrupt rate will drop as low as interrupts per second. All hardware requirements listed apply to use with Linux.

The user should run the Linux firmware kit from http: RxDescriptors This value specifies the number of receive buffer descriptors allocated by the driver. The Linux base drivers support the 2. 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. When a malicious driver attempts to send a spoofed packet, it is dropped by the hardware and not transmitted.

This parameter is supported only onand later adapters. For situations where low latency is vital such as cluster or grid computing, the algorithm can reduce latency even more when InterruptThrottleRate is set to mode 1.

In this case, use a lower number. Kernel panics and instability may be observed on any MSI-X hardware if you use irqbalance with kernels between 2.

This workaround skips resetting the Phy at shutdown for the initial silicon releases of ICH8 systems. Auto-negotiation is disabled, and the AutoNeg parameter is ignored. This is caused by the way the Linux kernel reports this stressed condition. Strip the CRC from received packets before sending up the network stack.

To resolve this issue build the driver step 4 above using the command:. To solve this issue, create the version. WoL will be enabled on the system during the next shut down or reboot.

This parameter is not supported on the based adapter. The driver utilizes the ethtool interface for driver configuration and diagnostics, as well as displaying igbvr information.

When ee is loaded with default settings and multiple adapters are in use simultaneously, the CPU utilization may increase non-linearly.

If the system is reporting dropped transmits, this value may be set too high causing the driver to run out of available transmit descriptors.

This results in unbalanced receive traffic. Several adapters with the chipset display “TX unit hang” messages during normal operation with the ee driver. Intel is not supplying patches against the kernel source to allow for static linking of the driver. Using Jumbo frames at 10 or Mbps is not supported and may result in poor performance or loss of link.
