result of not disabling LRO when combined with ip forwarding or bridging can be
low throughput or even a kernel panic.
The ixgbe driver supports the Large Receive Offload (LRO) feature.
This option offers the lowest CPU utilization for receives but is completely
incompatible with *routing/ip forwarding* and *bridging*. If enabling ip
forwarding or bridging is a requirement, it is necessary to disable LRO using
compile time options as noted in the LRO section later in this document. The
result of not disabling LRO when combined with ip forwarding or bridging can be
low throughput or even a kernel panic.
In a virtualized environment, on Intel(R) Ethernet Server Adapters that support
SR-IOV, the virtual function (VF) may be subject to malicious behavior.
Software-generated layer two frames, like IEEE 802.3x (link flow control), IEEE
802.1Qbb (priority based flow-control), and others of this type, are not
expected and can throttle traffic between the host and the virtual switch,
reducing performance. To resolve this issue, configure all SR-IOV enabled ports
for VLAN tagging. This configuration allows unexpected, and potentially
malicious, frames to be dropped.

Pull Requests are the heart of collaboration on GitHub. When you open a pull request, you’re proposing your changes and
requesting that someone review and pull in your contribution and merge them into their branch.
Pull requests show diffs, or differences, of the content from both branches. The changes, additions, and subtractions are
shown in green and red.
By using GitHub’s @mention system in your pull request message, you can ask for feedback from specific people or teams,
whether they’re down the hall or 10 time zones away.
You can even open pull requests in your own repository and merge them yourself. It’s a great way to learn the GitHub flow before
working on larger projects.

Configuring SR-IOV for improved network security
------------------------------------------------
In a virtualized environment, on Intel(R) Ethernet Server Adapters that support
SR-IOV, the virtual function (VF) may be subject to malicious behavior.
Software-generated layer two frames, like IEEE 802.3x (link flow control), IEEE
802.1Qbb (priority based flow-control), and others of this type, are not
expected and can throttle traffic between the host and the virtual switch,
reducing performance. To resolve this issue, configure all SR-IOV enabled ports
for VLAN tagging. This configuration allows unexpected, and potentially
malicious, frames to be dropped.
Overview
--------
This driver supports kernel versions 2.6.x and newer.
Driver information can be obtained using ethtool, lspci, and ifconfig.
Instructions on updating ethtool can be found in the section Additional
Configurations later in this document.
This driver is only supported as a loadable module at this time. Intel is not
supplying patches against the kernel source to allow for static linking of the
drivers.
For questions related to hardware requirements, refer to the documentation
supplied with your Intel adapter. All hardware requirements listed apply to use
with Linux.

Building and Installation
-------------------------
To build a binary RPM* package of this driver, run 'rpmbuild -tb
ixgbe-<x.x.x>.tar.gz', where <x.x.x> is the version number for the driver tar
file.
Note: For the build to work properly, the currently running kernel MUST match
the version and configuration of the installed kernel sources. If you have just
recompiled the kernel reboot the system before building.
Note: RPM functionality has only been tested in Red Hat distributions.
_lbank_line_
1. Move the base driver tar file to the directory of your choice. For
example, use '/home/username/ixgbe' or '/usr/local/src/ixgbe'.
2. Untar/unzip the archive, where <x.x.x> is the version number for the
driver tar file:
tar zxf ixgbe-<x.x.x>.tar.gz
3. Change to the driver src directory, where <x.x.x> is the version number
for the driver tar:
cd ixgbe-<x.x.x>/src/
4. Compile the driver module:
# make install
The binary will be installed as:
/lib/modules/<KERNEL
VERSION>/updates/drivers/net/ethernet/intel/ixgbe/ixgbe.ko

The install location listed above is the default location. This may differ
for various Linux distributions.
5. Load the module using the modprobe command:
modprobe <ixgbe> [parameter=port1_value,port2_value]
Make sure that any older ixgbe drivers are removed from the kernel before
loading the new module:
rmmod ixgbe; modprobe ixgbe
6. Assign an IP address to the interface by entering the following,
where ethX is the interface name that was shown in dmesg after modprobe:
ip address add <IP_address>/<netmask bits> dev ethX
7. Verify that the interface works. Enter the following, where IP_address
is the IP address for another machine on the same subnet as the interface
that is being tested:
ping <IP_address>
Note: For certain distributions like (but not limited to) RedHat Enterprise
Linux 7 and Ubuntu, once the driver is installed the initrd/initramfs file may
need to be updated to prevent the OS loading old versions of the ixgbe driver.
The dracut utility may be used on RedHat distributions:
# dracut --force
For Ubuntu:
# update-initramfs -u
================================================================================
Command Line Parameters
-----------------------
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:
modprobe ixgbe [<option>=<VAL1>,<VAL2>,...]
There needs to be a <VAL#> for each network port in the system supported by
this driver. The values will be applied to each instance, in function order.
For example:
modprobe ixgbe InterruptThrottleRate=16000,16000
In this case, there are two network ports supported by ixgbe in the system.
The default value for each parameter is generally the recommended setting,
unless otherwise noted.

RSS
---
Valid Range: 0-16
0 = Assign up to the lesser value of the number of CPUs or the number of queues
X = Assign X queues, where X is less than or equal to the maximum number of
queues (16 queues).
RSS also effects the number of transmit queues allocated on 2.6.23 and
newer kernels with CONFIG_NETDEVICES_MULTIQUEUE set in the kernel .config file.
CONFIG_NETDEVICES_MULTIQUEUE only exists from 2.6.23 to 2.6.26. Other options
enable multiqueue in 2.6.27 and newer kernels.
Multiqueue
----------
Valid Range:
0, 1
0 = Disables Multiple Queue support
1 = Enabled Multiple Queue support (a prerequisite for RSS)
Direct Cache Access (DCA)
-------------------------
Valid Range: 0, 1
0 = Disables DCA support in the driver
1 = Enables DCA support in the driver
If the driver is enabled for DCA, this parameter allows load-time control of
the feature.
Note: DCA is not supported on X550-based adapters.

IntMode
-------
Valid Range: 0-2 (0 = Legacy Int, 1 = MSI and 2 = MSI-X)
IntMode controls allow load time control over the type of interrupt
registered for by the driver. MSI-X is required for multiple queue
support, and some kernels and combinations of kernel .config options
will force a lower level of interrupt support.
'cat /proc/interrupts' will show different values for each type of interrupt.
InterruptThrottleRate
---------------------
Valid Range:
0=off
1=dynamic
<min_ITR>-<max_ITR>
Interrupt Throttle Rate controls the number of interrupts each interrupt
vector can generate per second. Increasing ITR lowers latency at the cost of
increased CPU utilization, though it may help throughput in some circumstances.
0 = Setting InterruptThrottleRate to 0 turns off any interrupt moderation
and may improve small packet latency. However, this is generally not
suitable for bulk throughput traffic due to the increased CPU utilization
of the higher interrupt rate.
NOTES:
- On 82599, and X540, and X550-based adapters, disabling InterruptThrottleRate
will also result in the driver disabling HW RSC.
- On 82598-based adapters, disabling InterruptThrottleRate will also
result in disabling LRO (Large Receive Offloads).
1 = Setting InterruptThrottleRate to Dynamic mode attempts to moderate
interrupts per vector while maintaining very low latency. This can
sometimes cause extra CPU utilization. If planning on deploying ixgbe
in a latency sensitive environment, this parameter should be considered.
<min_ITR>-<max_ITR> = 956-488281
Setting InterruptThrottleRate to a value greater or equal to <min_ITR>
will program the adapter to send at most that many interrupts
per second, even if more packets have come in. This reduces interrupt load
on the system and can lower CPU utilization under heavy load, but will
increase latency as packets are not processed as quickly.
LLI (Low Latency Interrupts)
----------------------------
LLI allows for immediate generation of an interrupt upon processing receive
packets that match certain criteria as set by the parameters described below.
LLI parameters are not enabled when Legacy interrupts are used. You must be
using MSI or MSI-X (see cat /proc/interrupts) to successfully use LLI.
Note: LLI is not supported on X550-based adapters.
LLIPort
-------
Valid Range: 0-65535
LLI is configured with the LLIPort command-line parameter, which specifies
which TCP port should generate Low Latency Interrupts.
For example, using LLIPort=80 would cause the board to generate an immediate
interrupt upon receipt of any packet sent to TCP port 80 on the local machine.
WARNING: Enabling LLI can result in an excessive number of interrupts/second
that may cause problems with the system and in some cases may cause a kernel
panic.
Note: LLI is not supported on X550-based adapters.
