Intel i210 driver parameters
Will also result in the driver disabling HW RSC. On 82599, X540, and X550-based adapters, disabling InterruptThrottleRate Suitable for bulk throughput traffic due to the increased CPU utilization Increased CPU utilization, though it may help throughput in some circumstances.Ġ = Setting InterruptThrottleRate to 0 turns off any interrupt moderationĪnd may improve small packet latency. Increasing ITR lowers latency at the cost of Interrupt Throttle Rate controls the number of interrupts each interrupt This information is accessed by the hardware. A descriptor describes a data buffer and attributes related to the dataīuffer. For more information about the command line parameters, see the application The default value for each parameter is generally the recommended setting, In this case, there are two network ports supported by igb in the system. Modprobe igb InterruptThrottleRate=16000,16000
The values will be applied to each instance, in function order. There needs to be a for each network port in the system supported by If the driver is built as a module, the following optional parameters are usedīy entering them on the command line with the modprobe command using this Linux 7 and Ubuntu, once the driver is installed the initrd/initramfsįile may need to be updated to prevent the OS loading old versions If your kernel supports DCA, the driver will build by default with DCA enabled.įor certain distributions like (but not limited to) RedHat Enterprise Is the IP address for another machine on the same subnet as the interface Where ethX is the interface name that was shown in dmesg after modprobe:ħ. Assign an IP address to the interface by entering the following, Make sure that any older igb drivers are removed from the kernel beforeĦ. Load the module using the modprobe command:
#Intel i210 driver parameters install
The install location listed above is the default location. lib/modules//kernel/drivers/net/igb/igb.o Change to the driver src directory, where is the version number Untar/unzip the archive, where is the version number for theģ. ForĮxample, use '/home/username/igb' or '/usr/local/src/igb'.Ģ. Move the base driver tar file to the directory of your choice. RPM functionality has only been tested in Red Hat distributions.ġ. Just recompiled the kernel reboot the system before building. The version and configuration of the installed kernel sources. For the build to work properly, the currently running kernel MUST match ', where is the version number for the driver tar file. To build a binary RPM* package of this driver, run 'rpmbuild -tb

Instructions on updating ethtool can be found in the section Additionalįor information on how to identify your adapter, go to the Adapter &įor the latest Intel network drivers, refer to theįollowing website and select your adapter. The driver information previously displayed in the /proc file system is notĭriver information can be obtained using ethtool, lspci, and ifconfig. The igb driver supports IEEE 1588 time stamping for kernels 2.6.30 and newer. This is included in supported Linux kernels.Ĭhannel Bonding documentation can be found in the Linux kernel source: The following features are now available in supported kernels:Īdapter teaming is implemented using the native Linux Channel bonding All hardware requirements listed apply to Not supplying patches against the kernel source to allow for static linking ofįor questions related to hardware requirements, refer to the documentation This driver is only supported as a loadable module at this time. The igb driver supports 2.5 Gbps operating speed on 2500BASE-KX only for It includes support for Itanium(R)2 based systems. The Linux* base driver supports the following kernel versions: This document describes the igb Linux base driver. This configuration allows unexpected, and potentially malicious, frames to be dropped. To resolve this issue, configure all SR-IOV enabled ports for VLAN tagging. Software-generated frames are not expected and can throttle traffic between the host and the virtual switch, reducing performance. In a virtualized environment, on Intel(R) Server Adapters that support SR-IOV, the virtual function (VF) may be subject to malicious behavior.
