It is highly recommended to always use the most recent driver version available.
Do not forget to check with our site as often as possible in order to stay updated on the latest drivers, software and games.
Try to set a system restore point before installing a device driver. This will help if you installed a wrong driver. Problems can arise when your hardware device is too old or not supported any longer.

Identifying Your Adapter
Command Line Parameters
Additional Configurations
Support

For information on how to identify your adapter, and for the latest Intelnetwork drivers, refer to the Intel Support website:http://www.intel.com/support

If the driver is built as a module, the following optional parameters are usedby entering them on the command line with the modprobe command using thissyntax:

There needs to be a <VAL#> for each network port in the system supported bythis driver. The values will be applied to each instance, in function order.For example:

In this case, there are two network ports supported by igb in the system.

NOTE: A descriptor describes a data buffer and attributes related to the databuffer. This information is accessed by the hardware.

max_vfs¶

Valid Range:	0-7

This parameter adds support for SR-IOV. It causes the driver to spawn up tomax_vfs worth of virtual functions. If the value is greater than 0 it willalso force the VMDq parameter to be 1 or more.

The parameters for the driver are referenced by position. Thus, if you have adual port adapter, or more than one adapter in your system, and want N virtualfunctions per port, you must specify a number for each port with each parameterseparated by a comma. For example:

This will spawn 4 VFs on the first port.

This will spawn 2 VFs on the first port and 4 VFs on the second port.

NOTE: Caution must be used in loading the driver with these parameters.Depending on your system configuration, number of slots, etc., it is impossibleto predict in all cases where the positions would be on the command line.

NOTE: Neither the device nor the driver control how VFs are mapped into configspace. Bus layout will vary by operating system. On operating systems thatsupport it, you can check sysfs to find the mapping.

NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filteringand VLAN tag stripping/insertion will remain enabled. Please remove the oldVLAN filter before the new VLAN filter is added. For example:

Debug¶

Valid Range:	0-16 (0=none,...,16=all)
Default Value:	0

This parameter adjusts the level debug messages displayed in the system logs.

Jumbo Frames¶

Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)to a value larger than the default value of 1500.

Use the ifconfig command to increase the MTU size. For example, enter thefollowing where <x> is the interface number:

Alternatively, you can use the ip command as follows:

This setting is not saved across reboots. The setting change can be madepermanent by adding ‘MTU=9000’ to the file:

For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
For SLES: /etc/sysconfig/network/<config_file>

NOTE: The maximum MTU setting for Jumbo Frames is 9216. This value coincideswith the maximum Jumbo Frames size of 9234 bytes.

NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result inpoor performance or loss of link.

ethtool¶

The driver utilizes the ethtool interface for driver configuration anddiagnostics, as well as displaying statistical information. The latest ethtoolversion is required for this functionality. Download it at:

Enabling Wake on LAN* (WoL)¶

WoL is configured through the ethtool* utility.

WoL will be enabled on the system during the next shut down or reboot. Forthis driver version, in order to enable WoL, the igb driver must be loadedprior to shutting down or suspending the system.

NOTE: Wake on LAN is only supported on port A of multi-port devices. AlsoWake On LAN is not supported for the following device:- Intel(R) Gigabit VT Quad Port Server Adapter

Multiqueue¶

In this mode, a separate MSI-X vector is allocated for each queue and one for“other” interrupts such as link status change and errors. All interrupts arethrottled via interrupt moderation. Interrupt moderation must be used to avoidinterrupt storms while the driver is processing one interrupt. The moderationvalue should be at least as large as the expected time for the driver toprocess an interrupt. Multiqueue is off by default.

Vfs 004 Driver For Mac Download

REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not found,the system will fallback to MSI or to Legacy interrupts. This driver supportsreceive multiqueue on all kernels that support MSI-X.

NOTE: On some kernels a reboot is required to switch between single queue modeand multiqueue mode or vice-versa.

MAC and VLAN anti-spoofing feature¶

When a malicious driver attempts to send a spoofed packet, it is dropped by thehardware and not transmitted.

An interrupt is sent to the PF driver notifying it of the spoof attempt. When aspoofed packet is detected, the PF driver will send the following message tothe system log (displayed by the “dmesg” command):Spoof event(s) detected on VF(n), where n = the VF that attempted to do thespoofing

Setting MAC Address, VLAN and Rate Limit Using IProute2 Tool¶

You can set a MAC address of a Virtual Function (VF), a default VLAN and therate limit using the IProute2 tool. Download the latest version of theIProute2 tool from Sourceforge if your version does not have all the featuresyou require.

Credit Based Shaper (Qav Mode)¶

When enabling the CBS qdisc in the hardware offload mode, traffic shaping usingthe CBS (described in the IEEE 802.1Q-2018 Section 8.6.8.2 and discussed in theAnnex L) algorithm will run in the i210 controller, so it’s more accurate anduses less CPU.

When using offloaded CBS, and the traffic rate obeys the configured rate(doesn’t go above it), CBS should have little to no effect in the
