To build igb driver with DCA: Increasing this value allows the driver to queue more transmits. This setting is not saved across reboots. If mediaopt is not specified, the driver defaults to half-duplex. The AutoNeg parameter is used when more control is required over the auto-negotiation process. Adapters that have 4 ports behind a PCIe bridge may be incompatible with some systems. Many popular Linux distributions ship with tools to make these changes for you.

This value specifies the number of receive buffer descriptors allocated by the driver. For this driver version, in order to enable WoL, the ee driver must be loaded prior to shutting down or suspending the system.

If you encounter liux problem in an adapter, and the chipset is an based one, you can verify that your adapter needs the fix by using ethtool:. 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. On bootup I noticed that it will not initialize this NIC but I am able to manually insert the e module and bring it up.
If you have a machine with a BMC enabled but cannot receive IPMI traffic after loading lonux enabling the driver, try disabling this feature.
To build igb driver with DCA: This driver 82541gu supports VLANs. For this driver version, in order to enable WoL, the e driver must be loaded prior to shutting down or suspending the system.
After determining the type of incoming traffic in the last timeframe, it will adjust the InterruptThrottleRate to an appropriate value for that traffic. The Linux Base Drivers support the 2.
Linux Driver for Intel® Gigabit Network Connections
The identification LEDs of the adapters supported by the em driver can be controlled via the led 4 API for localization purposes. 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 ee. That was causing the issue with pings not working when eth1 was up.
Due to limited support for PCI-Express in 2. The and based adapters can handle up to descriptors, while others can have up to If both Duplex and the link partner are set to auto-negotiate, the board auto-detects the correct duplex. The script can be downloaded at http: MTU designates the frame size.
RxDescriptors This 82541gj specifies the number of receive buffer descriptors allocated by the driver. Turning on DMA Coalescing may save energy with kernel 2. In order to limit the CPU utilization without impacting the overall throughput, we recommend that you load the driver as follows: This value is the number of transmit descriptors allocated by the driver.
FreeBSD Manual Pages
Defines the direction in which data is allowed to flow. LLI allows for immediate generation of an interrupt upon processing receive packets that match certain criteria as set by the parameters described below. This parameter is only useful when interrupt affinity is specified, otherwise some portion of the time the interrupt 82541hi run on a different core than the memory is allocated on, causing slower memory access and impacting throughput, CPU, liunx both.
liux On some kernels a reboot is required to switch between a single queue mode and multiqueue modes, or vice-versa. This option allows for the ability of IEEE If you believe your system needs to disable this style of interrupt, the driver can be built and installed with the command:. DMA Coalescing is effective in helping potentially saving the platform power only when it is enabled across all active ports.
Instructions on updating ethtool can limux found in the section Additional Configurations later in this document. If mediaopt is not specified, the driver defaults to half-duplex.

There are other conditions which may result in “TX Timeout”, which will not be resolved by the use of the TxDescriptorStep parameter. This value delays the generation of receive interrupts in units of 1. This value represents the size-order of each transmit descriptor.
