====================
Intel Wired LAN Doc Updates 2018-10-18

This series contains documentation fixes and updates for Intel wired
LAN drivers.

The following was done:
 - Updated incorrect URLs
 - removed document references which did not apply to the current
   in-kernel drivers
 - added documentation for fm10k driver
 - added missing documentation on existing or new features
 - added SPDX headers to all the documentation files

Lastly, the documentation was converted over to the RST (reStructured
Text) format, so that 'make htmldocs' produces pretty html driver
documentation for our drivers.

Identifying Your Adapter
========================
The driver in this release is compatible with devices based on the Intel(R)
Ethernet Multi-host Controller.
For information on how to identify your adapter, and for the latest Intel
network drivers, refer to the Intel Support website:
http://www.intel.com/support
Flow Control
------------
The Intel(R) Ethernet Switch Host Interface Driver does not support Flow
Control. It will not send pause frames. This may result in dropped frames.
Virtual Functions (VFs)
-----------------------
Use sysfs to enable VFs.
Valid Range: 0-64
For example::
echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs //enable VFs
echo 0 > /sys/class/net/$dev/device/sriov_numvfs //disable VFs
NOTE: Neither the device nor the driver control how VFs are mapped into config
space. Bus layout will vary by operating system. On operating systems that
support it, you can check sysfs to find the mapping.
NOTE: When SR-IOV mode is enabled, hardware VLAN filtering and VLAN tag
stripping/insertion will remain enabled. Please remove the old VLAN filter
before the new VLAN filter is added. For example::
ip link set eth0 vf 0 vlan 100 // set vlan 100 for VF 0
ip link set eth0 vf 0 vlan 0 // Delete vlan 100
ip link set eth0 vf 0 vlan 200 // set a new vlan 200 for VF 0
Additional Features and Configurations
======================================
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 the
following where <x> is the interface number::
ifconfig eth<x> mtu 9000 up
Alternatively, you can use the ip command as follows::
ip link set mtu 9000 dev eth<x>
ip link set up dev eth<x>
This setting is not saved across reboots. The setting change can be made
permanent 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 15342. This value coincides
with the maximum Jumbo Frames size of 15364 bytes.
NOTE: This driver will attempt to use multiple page sized buffers to receive
each jumbo packet. This should help to avoid buffer starvation issues when
allocating receive packets.
Generic Receive Offload, aka GRO
--------------------------------
The driver supports the in-kernel software implementation of GRO. GRO has
shown that by coalescing Rx traffic into larger chunks of data, CPU
utilization can be significantly reduced when under large Rx load. GRO is an
evolution of the previously-used LRO interface. GRO is able to coalesce
other protocols besides TCP. It's also safe to use with configurations that
are problematic for LRO, namely bridging and iSCSI.
Supported ethtool Commands and Options for Filtering
----------------------------------------------------
-n --show-nfc
Retrieves the receive network flow classification configurations.
rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6
Retrieves the hash options for the specified network traffic type.
-N --config-nfc
Configures the receive network flow classification.
rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 m|v|t|s|d|f|n|r
Configures the hash options for the specified network traffic type.
- udp4: UDP over IPv4
- udp6: UDP over IPv6
- f Hash on bytes 0 and 1 of the Layer 4 header of the rx packet.
- n Hash on bytes 2 and 3 of the Layer 4 header of the rx packet.

Identifying Your Adapter
========================
The driver in this release is compatible with the Intel Ethernet
Controller XL710 Family.
For more information on how to identify your adapter, go to the Adapter &
Driver ID Guide at:
http://support.intel.com/support/network/sb/CS-012904.htm
Enabling the driver
===================
The driver is enabled via the standard kernel configuration system,
using the make command:
make config/oldconfig/menuconfig/etc.
The driver is located in the menu structure at:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Ethernet driver support
-> Intel devices
-> Intel(R) Ethernet Controller XL710 Family
Additional Configurations
=========================
Generic Receive Offload (GRO)
-----------------------------
The driver supports the in-kernel software implementation of GRO. GRO has
shown that by coalescing Rx traffic into larger chunks of data, CPU
utilization can be significantly reduced when under large Rx load. GRO is
an evolution of the previously-used LRO interface. GRO is able to coalesce
other protocols besides TCP. It's also safe to use with configurations that
are problematic for LRO, namely bridging and iSCSI.
Ethtool
-------
The driver utilizes the ethtool interface for driver configuration and
diagnostics, as well as displaying statistical information. The latest
ethtool version is required for this functionality.
The latest release of ethtool can be found from
https://www.kernel.org/pub/software/network/ethtool
Flow Director n-ntuple traffic filters (FDir)
---------------------------------------------
The driver utilizes the ethtool interface for configuring ntuple filters,
via "ethtool -N <device> <filter>".
The sctp4, ip4, udp4, and tcp4 flow types are supported with the standard
fields including src-ip, dst-ip, src-port and dst-port. The driver only
supports fully enabling or fully masking the fields, so use of the mask
fields for partial matches is not supported.
Additionally, the driver supports using the action to specify filters for a
Virtual Function. You can specify the action as a 64bit value, where the
lower 32 bits represents the queue number, while the next 8 bits represent
which VF. Note that 0 is the PF, so the VF identifier is offset by 1. For
example:
... action 0x800000002 ...
Would indicate to direct traffic for Virtual Function 7 (8 minus 1) on queue
2 of that VF.
The driver also supports using the user-defined field to specify 2 bytes of
arbitrary data to match within the packet payload in addition to the regular
fields. The data is specified in the lower 32bits of the user-def field in
the following way:
+----------------------------+---------------------------+
| 31 28 24 20 16 | 15 12 8 4 0|
+----------------------------+---------------------------+
| offset into packet payload | 2 bytes of flexible data |
+----------------------------+---------------------------+
As an example,
... user-def 0x4FFFF ....
means to match the value 0xFFFF 4 bytes into the packet payload. Note that
the offset is based on the beginning of the payload, and not the beginning
of the packet. Thus
flow-type tcp4 ... user-def 0x8BEAF ....
would match TCP/IPv4 packets which have the value 0xBEAF 8bytes into the
TCP/IPv4 payload.
For ICMP, the hardware parses the ICMP header as 4 bytes of header and 4
bytes of payload, so if you want to match an ICMP frames payload you may need
to add 4 to the offset in order to match the data.
Furthermore, the offset can only be up to a value of 64, as the hardware
will only read up to 64 bytes of data from the payload. It must also be even
as the flexible data is 2 bytes long and must be aligned to byte 0 of the
packet payload.
When programming filters, the hardware is limited to using a single input
set for each flow type. This means that it is an error to program two
different filters with the same type that don't match on the same fields.
Thus the second of the following two commands will fail:
ethtool -N <device> flow-type tcp4 src-ip 192.168.0.7 action 5
ethtool -N <device> flow-type tcp4 dst-ip 192.168.15.18 action 1
This is because the first filter will be accepted and reprogram the input
set for TCPv4 filters, but the second filter will be unable to reprogram the
input set until all the conflicting TCPv4 filters are first removed.
Note that the user-defined flexible offset is also considered part of the
input set and cannot be programmed separately for multiple filters of the
same type. However, the flexible data is not part of the input set and
multiple filters may use the same offset but match against different data.
Data Center Bridging (DCB)
--------------------------
DCB configuration is not currently supported.
FCoE
----
The driver supports Fiber Channel over Ethernet (FCoE) and Data Center
Bridging (DCB) functionality. Configuring DCB and FCoE is outside the scope
of this driver doc. Refer to http://www.open-fcoe.org/ for FCoE project
information and http://www.open-lldp.org/ or email list
e1000-eedc@lists.sourceforge.net for DCB information.
MAC and VLAN anti-spoofing feature
----------------------------------
When a malicious driver attempts to send a spoofed packet, it is dropped by
the hardware and not transmitted. An interrupt is sent to the PF driver
notifying it of the spoof attempt.
When a spoofed packet is detected the PF driver will send the following
message to the system log (displayed by the "dmesg" command):
Spoof event(s) detected on VF (n)
Where n=the VF that attempted to do the spoofing.

Identifying Your Adapter
========================
For information on how to identify your adapter, and for the latest Intel
network drivers, refer to the Intel Support website:
http://www.intel.com/support
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 igb [<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 igb max_vfs=2,4
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 data
buffer. 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 to
max_vfs worth of virtual functions. If the value is greater than 0 it will
also force the VMDq parameter to be 1 or more.
The parameters for the driver are referenced by position. Thus, if you have a
dual port adapter, or more than one adapter in your system, and want N virtual
functions per port, you must specify a number for each port with each parameter
separated by a comma. For example::
modprobe igb max_vfs=4
This will spawn 4 VFs on the first port.
::
modprobe igb max_vfs=2,4
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 impossible
to 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 config
space. Bus layout will vary by operating system. On operating systems that
support it, you can check sysfs to find the mapping.
NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
and VLAN tag stripping/insertion will remain enabled. Please remove the old
VLAN filter before the new VLAN filter is added. For example::
ip link set eth0 vf 0 vlan 100 // set vlan 100 for VF 0
ip link set eth0 vf 0 vlan 0 // Delete vlan 100
ip link set eth0 vf 0 vlan 200 // set a new vlan 200 for VF 0
Debug
-----
:Valid Range: 0-16 (0=none,...,16=all)
:Default Value: 0
This parameter adjusts the level debug messages displayed in the system logs.
Additional Features and Configurations
======================================
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 the
following where <x> is the interface number::
ifconfig eth<x> mtu 9000 up
Alternatively, you can use the ip command as follows::
ip link set mtu 9000 dev eth<x>
ip link set up dev eth<x>
This setting is not saved across reboots. The setting change can be made
permanent 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 coincides
with the maximum Jumbo Frames size of 9234 bytes.
NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
poor performance or loss of link.
ethtool
-------
The driver utilizes the ethtool interface for driver configuration and
diagnostics, as well as displaying statistical information. The latest ethtool
version is required for this functionality. Download it at:
https://www.kernel.org/pub/software/network/ethtool/
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. For
this driver version, in order to enable WoL, the igb driver must be loaded
prior to shutting down or suspending the system.
NOTE: Wake on LAN is only supported on port A of multi-port devices. Also
Wake 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 are
throttled via interrupt moderation. Interrupt moderation must be used to avoid
interrupt storms while the driver is processing one interrupt. The moderation
value should be at least as large as the expected time for the driver to
process an interrupt. Multiqueue is off by default.
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 supports
receive multiqueue on all kernels that support MSI-X.
NOTE: On some kernels a reboot is required to switch between single queue mode
and 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 the
hardware and not transmitted.
An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
spoofed packet is detected, the PF driver will send the following message to
the system log (displayed by the "dmesg" command):
Spoof event(s) detected on VF(n), where n = the VF that attempted to do the
spoofing
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 the
rate limit using the IProute2 tool. Download the latest version of the
IProute2 tool from Sourceforge if your version does not have all the features
you require.
