In This Release
===============
This file describes the Linux* Base Driver for the Intel(R) PRO/1000 Family
of Adapters. This driver includes support for Itanium(R)2-based systems.
For questions related to hardware requirements, refer to the documentation
supplied with your Intel PRO/1000 adapter. All hardware requirements listed
apply to use with Linux.
The following features are now available in supported kernels:
- Native VLANs
- Channel Bonding (teaming)
- SNMP
Channel Bonding documentation can be found in the Linux kernel source:
/Documentation/networking/bonding.txt
The driver information previously displayed in the /proc filesystem is not
supported in this release. Alternatively, you can use ethtool (version 1.6
or later), lspci, and ifconfig to obtain the same information.
Instructions on updating ethtool can be found in the section "Additional
Configurations" later in this document.
NOTE: The Intel(R) 82562v 10/100 Network Connection only provides 10/100
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 e1000 [<option>=<VAL1>,<VAL2>,...]
For example, with two PRO/1000 PCI adapters, entering:
modprobe e1000 TxDescriptors=80,128
loads the e1000 driver with 80 TX descriptors for the first adapter and
128 TX descriptors for the second adapter.
The default value for each parameter is generally the recommended setting,
unless otherwise noted.

The hardware can handle many more small packets per second however, and

The algorithm classifies the incoming traffic every interval into
classes. Once the class is determined, the InterruptThrottleRate value is

classes. Once the class is determined, the InterruptThrottleRate value is
adjusted to suit that traffic type the best. There are three classes defined:

for small amounts of traffic and/or a significant percentage of small
packets; and "Lowest latency", for almost completely small packets or
packets; and "Lowest latency", for almost completely small packets or
minimal traffic.

In dynamic conservative mode, the InterruptThrottleRate value is set to 4000
for traffic that falls in class "Bulk traffic". If traffic falls in the "Low
latency" or "Lowest latency" class, the InterruptThrottleRate is increased
stepwise to 20000. This default mode is suitable for most applications.
For situations where low latency is vital such as cluster or
grid computing, the algorithm can reduce latency even more when
InterruptThrottleRate is set to mode 1. In this mode, which operates
the same as mode 3, the InterruptThrottleRate will be increased stepwise to
the same as mode 3, the InterruptThrottleRate will be increased stepwise to
70000 for traffic in class "Lowest latency".
In simplified mode the interrupt rate is based on the ratio of Tx and
Rx traffic. If the bytes per second rate is approximately equal, the
interrupt rate will drop as low as 2000 interrupts per second. If the
traffic is mostly transmit or mostly receive, the interrupt rate could
be as high as 8000.
Setting InterruptThrottleRate to 0 turns off any interrupt moderation
and may improve small packet latency, but is generally not suitable

Valid Range: 1 (use every Tx Descriptor)

Default Value: 1 (use every Tx Descriptor)
On certain non-Intel architectures, it has been observed that intense TX
traffic bursts of short packets may result in an improper descriptor
writeback. If this occurs, the driver will report a "TX Timeout" and reset
the adapter, after which the transmit flow will restart, though data may
have stalled for as much as 10 seconds before it resumes.
The improper writeback does not occur on the first descriptor in a system
memory cache-line, which is typically 32 bytes, or 4 descriptors long.
Setting TxDescriptorStep to a value of 4 will ensure that all TX descriptors
are aligned to the start of a system memory cache line, and so this problem
will not occur.
NOTES: Setting TxDescriptorStep to 4 effectively reduces the number of
TxDescriptors available for transmits to 1/4 of the normal allocation.
This has a possible negative performance impact, which may be
compensated for by allocating more descriptors using the TxDescriptors
module parameter.
There are other conditions which may result in "TX Timeout", which will
not be resolved by the use of the TxDescriptorStep parameter. As the
issue addressed by this parameter has never been observed on Intel

Additional Configurations
=========================
Configuring the Driver on Different Distributions
-------------------------------------------------
Configuring a network driver to load properly when the system is started
is distribution dependent. Typically, the configuration process involves
adding an alias line to /etc/modules.conf or /etc/modprobe.conf as well
as editing other system startup scripts and/or configuration files. Many
popular Linux distributions ship with tools to make these changes for you.
To learn the proper way to configure a network device for your system,
refer to your distribution documentation. If during this process you are
asked for the driver or module name, the name for the Linux Base Driver
for the Intel(R) PRO/1000 Family of Adapters is e1000.
As an example, if you install the e1000 driver for two PRO/1000 adapters
(eth0 and eth1) and set the speed and duplex to 10full and 100half, add
the following to modules.conf or or modprobe.conf:
alias eth0 e1000
alias eth1 e1000
options e1000 Speed=10,100 Duplex=2,1
Viewing Link Messages
---------------------
Link messages will not be displayed to the console if the distribution is
restricting system messages. In order to see network driver link messages
on your console, set dmesg to eight by entering the following:

Known Issues
============
Dropped Receive Packets on Half-duplex 10/100 Networks
------------------------------------------------------
If you have an Intel PCI Express adapter running at 10mbps or 100mbps, half-
duplex, you may observe occasional dropped receive packets. There are no
workarounds for this problem in this network configuration. The network must
be updated to operate in full-duplex, and/or 1000mbps only.
Jumbo Frames System Requirement
-------------------------------
Memory allocation failures have been observed on Linux systems with 64 MB
of RAM or less that are running Jumbo Frames. If you are using Jumbo
Frames, your system may require more than the advertised minimum
requirement of 64 MB of system memory.
Performance Degradation with Jumbo Frames
-----------------------------------------
Degradation in throughput performance may be observed in some Jumbo frames
environments. If this is observed, increasing the application's socket
buffer size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values
may help. See the specific application manual and
/usr/src/linux*/Documentation/
networking/ip-sysctl.txt for more details.
Jumbo Frames on Foundry BigIron 8000 switch
-------------------------------------------
There is a known issue using Jumbo frames when connected to a Foundry
BigIron 8000 switch. This is a 3rd party limitation. If you experience
loss of packets, lower the MTU size.
Allocating Rx Buffers when Using Jumbo Frames
---------------------------------------------
Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
the available memory is heavily fragmented. This issue may be seen with PCI-X
adapters or with packet split disabled. This can be reduced or eliminated
by changing the amount of available memory for receive buffer allocation, by
increasing /proc/sys/vm/min_free_kbytes.
Multiple Interfaces on Same Ethernet Broadcast Network
------------------------------------------------------
Due to the default ARP behavior on Linux, it is not possible to have
one system on two IP networks in the same Ethernet broadcast domain
(non-partitioned switch) behave as expected. All Ethernet interfaces
will respond to IP traffic for any IP address assigned to the system.
This results in unbalanced receive traffic.
If you have multiple interfaces in a server, either turn on ARP
filtering by entering:
echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
(this only works if your kernel's version is higher than 2.4.5),
NOTE: This setting is not saved across reboots. The configuration
change can be made permanent by adding the line:
net.ipv4.conf.all.arp_filter = 1
to the file /etc/sysctl.conf
or,
install the interfaces in separate broadcast domains (either in
different switches or in a switch partitioned to VLANs).
82541/82547 can't link or are slow to link with some link partners
-----------------------------------------------------------------
There is a known compatibility issue with 82541/82547 and some
low-end switches where the link will not be established, or will
be slow to establish. In particular, these switches are known to
be incompatible with 82541/82547:
Planex FXG-08TE
I-O Data ETG-SH8
To workaround this issue, the driver can be compiled with an override
of the PHY's master/slave setting. Forcing master or forcing slave
mode will improve time-to-link.
# make CFLAGS_EXTRA=-DE1000_MASTER_SLAVE=<n>
Where <n> is:
0 = Hardware default
1 = Master mode
2 = Slave mode
3 = Auto master/slave
Disable rx flow control with ethtool
------------------------------------
In order to disable receive flow control using ethtool, you must turn
off auto-negotiation on the same command line.
For example:
ethtool -A eth? autoneg off rx off
Unplugging network cable while ethtool -p is running
----------------------------------------------------
In kernel versions 2.5.50 and later (including 2.6 kernel), unplugging
the network cable while ethtool -p is running will cause the system to
become unresponsive to keyboard commands, except for control-alt-delete.
Restarting the system appears to be the only remedy.

=======================
The default value for each parameter is generally the recommended setting,
unless otherwise noted.
NOTES: For more information about the InterruptThrottleRate,
RxIntDelay, TxIntDelay, RxAbsIntDelay, and TxAbsIntDelay
parameters, see the application note at:
http://www.intel.com/design/network/applnots/ap450.htm
InterruptThrottleRate
---------------------
Valid Range: 0,1,3,4,100-100000 (0=off, 1=dynamic, 3=dynamic conservative,
4=simplified balancing)
Default Value: 3
The driver can limit the amount of interrupts per second that the adapter
will generate for incoming packets. 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.
Setting InterruptThrottleRate to a value greater or equal to 100
will program the adapter to send out a maximum of 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.
The driver has two adaptive modes (setting 1 or 3) in which
it dynamically adjusts the InterruptThrottleRate value based on the traffic
that it receives. After determining the type of incoming traffic in the last
timeframe, it will adjust the InterruptThrottleRate to an appropriate value
for that traffic.
The algorithm classifies the incoming traffic every interval into
classes. Once the class is determined, the InterruptThrottleRate value is
adjusted to suit that traffic type the best. There are three classes defined:
"Bulk traffic", for large amounts of packets of normal size; "Low latency",
for small amounts of traffic and/or a significant percentage of small
packets; and "Lowest latency", for almost completely small packets or
minimal traffic.
In dynamic conservative mode, the InterruptThrottleRate value is set to 4000
for traffic that falls in class "Bulk traffic". If traffic falls in the "Low
latency" or "Lowest latency" class, the InterruptThrottleRate is increased
stepwise to 20000. This default mode is suitable for most applications.
For situations where low latency is vital such as cluster or
grid computing, the algorithm can reduce latency even more when
InterruptThrottleRate is set to mode 1. In this mode, which operates
the same as mode 3, the InterruptThrottleRate will be increased stepwise to
70000 for traffic in class "Lowest latency".
In simplified mode the interrupt rate is based on the ratio of Tx and
Rx traffic. If the bytes per second rate is approximately equal the
interrupt rate will drop as low as 2000 interrupts per second. If the
traffic is mostly transmit or mostly receive, the interrupt rate could
be as high as 8000.
Setting InterruptThrottleRate to 0 turns off any interrupt moderation
and may improve small packet latency, but is generally not suitable
for bulk throughput traffic.
NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
RxAbsIntDelay parameters. In other words, minimizing the receive
and/or transmit absolute delays does not force the controller to
generate more interrupts than what the Interrupt Throttle Rate
allows.
NOTE: When e1000e is loaded with default settings and multiple adapters
are in use simultaneously, the CPU utilization may increase non-
linearly. In order to limit the CPU utilization without impacting
the overall throughput, we recommend that you load the driver as
follows:
modprobe e1000e InterruptThrottleRate=3000,3000,3000
This sets the InterruptThrottleRate to 3000 interrupts/sec for
the first, second, and third instances of the driver. The range
of 2000 to 3000 interrupts per second works on a majority of
systems and is a good starting point, but the optimal value will
be platform-specific. If CPU utilization is not a concern, use
RX_POLLING (NAPI) and default driver settings.
RxIntDelay
----------
Valid Range: 0-65535 (0=off)
Default Value: 0
This value delays the generation of receive interrupts in units of 1.024
microseconds. Receive interrupt reduction can improve CPU efficiency if
properly tuned for specific network traffic. Increasing this value adds
extra latency to frame reception and can end up decreasing the throughput
of TCP traffic. If the system is reporting dropped receives, this value
may be set too high, causing the driver to run out of available receive
descriptors.
CAUTION: When setting RxIntDelay to a value other than 0, adapters may
hang (stop transmitting) under certain network conditions. If
this occurs a NETDEV WATCHDOG message is logged in the system
event log. In addition, the controller is automatically reset,
restoring the network connection. To eliminate the potential
for the hang ensure that RxIntDelay is set to 0.
RxAbsIntDelay
-------------
Valid Range: 0-65535 (0=off)
Default Value: 8
This value, in units of 1.024 microseconds, limits the delay in which a
receive interrupt is generated. Useful only if RxIntDelay is non-zero,
this value ensures that an interrupt is generated after the initial
packet is received within the set amount of time. Proper tuning,
along with RxIntDelay, may improve traffic throughput in specific network
conditions.
TxIntDelay
----------
Valid Range: 0-65535 (0=off)
Default Value: 8
This value delays the generation of transmit interrupts in units of
1.024 microseconds. Transmit interrupt reduction can improve CPU
efficiency if properly tuned for specific network traffic. If the
system is reporting dropped transmits, this value may be set too high
causing the driver to run out of available transmit descriptors.
TxAbsIntDelay
-------------
Valid Range: 0-65535 (0=off)
Default Value: 32
This value, in units of 1.024 microseconds, limits the delay in which a
transmit interrupt is generated. Useful only if TxIntDelay is non-zero,
this value ensures that an interrupt is generated after the initial
packet is sent on the wire within the set amount of time. Proper tuning,
along with TxIntDelay, may improve traffic throughput in specific
network conditions.
Copybreak
---------
Valid Range: 0-xxxxxxx (0=off)
Default Value: 256
Driver copies all packets below or equaling this size to a fresh Rx
buffer before handing it up the stack.
This parameter is different than other parameters, in that it is a
single (not 1,1,1 etc.) parameter applied to all driver instances and
it is also available during runtime at
/sys/module/e1000e/parameters/copybreak
SmartPowerDownEnable
--------------------
Valid Range: 0-1
Default Value: 0 (disabled)
Allows PHY to turn off in lower power states. The user can set this parameter
in supported chipsets.
KumeranLockLoss
---------------
Valid Range: 0-1
Default Value: 1 (enabled)
This workaround skips resetting the PHY at shutdown for the initial
silicon releases of ICH8 systems.
IntMode
-------
Valid Range: 0-2 (0=legacy, 1=MSI, 2=MSI-X)
Default Value: 2
Allows changing the interrupt mode at module load time, without requiring a
recompile. If the driver load fails to enable a specific interrupt mode, the
driver will try other interrupt modes, from least to most compatible. The
interrupt order is MSI-X, MSI, Legacy. If specifying MSI (IntMode=1)
interrupts, only MSI and Legacy will be attempted.
CrcStripping
------------
Valid Range: 0-1
Default Value: 1 (enabled)
Strip the CRC from received packets before sending up the network stack. If
you have a machine with a BMC enabled but cannot receive IPMI traffic after
loading or enabling the driver, try disabling this feature.
WriteProtectNVM
---------------
Valid Range: 0-1
Default Value: 1 (enabled)
Set the hardware to ignore all write/erase cycles to the GbE region in the
ICHx NVM (non-volatile memory). This feature can be disabled by the
WriteProtectNVM module parameter (enabled by default) only after a hardware
reset, but the machine must be power cycled before trying to enable writes.
Note: the kernel boot option iomem=relaxed may need to be set if the kernel
config option CONFIG_STRICT_DEVMEM=y, if the root user wants to write the
NVM from user space via ethtool.
Additional Configurations
=========================
Jumbo Frames
------------
Jumbo Frames support is enabled by changing the MTU to a value larger than
the default of 1500. Use the ifconfig command to increase the MTU size.
For example:
ifconfig eth<x> mtu 9000 up
This setting is not saved across reboots.
Notes:
- The maximum MTU setting for Jumbo Frames is 9216. This value coincides
with the maximum Jumbo Frames size of 9234 bytes.
- Using Jumbo Frames at 10 or 100 Mbps is not supported and may result in
poor performance or loss of link.
- Some adapters limit Jumbo Frames sized packets to a maximum of
4096 bytes and some adapters do not support Jumbo Frames.
Ethtool
-------
The driver utilizes the ethtool interface for driver configuration and
diagnostics, as well as displaying statistical information. We
strongly recommend downloading the latest version of Ethtool at:
http://sourceforge.net/projects/gkernel.
Speed and Duplex
----------------
Speed and Duplex are configured through the Ethtool* utility. For
instructions, refer to the Ethtool man page.
Enabling Wake on LAN* (WoL)
---------------------------
WoL is configured through the Ethtool* utility. For instructions on
enabling WoL with Ethtool, refer to the Ethtool man page.
WoL will be enabled on the system during the next shut down or reboot.
For this driver version, in order to enable WoL, the e1000e driver must be
loaded when shutting down or rebooting the system.
In most cases Wake On LAN is only supported on port A for multiple port
adapters. To verify if a port supports Wake on LAN run ethtool eth<X>.

This option enables the workaround for the 743622 Cortex-A9
(r2p0..r2p2) erratum. Under very rare conditions, a faulty
optimisation in the Cortex-A9 Store Buffer may lead to data
corruption. This workaround sets a specific bit in the diagnostic
register of the Cortex-A9 which disables the Store Buffer
optimisation, preventing the defect from occurring. This has no
visible impact on the overall performance or power consumption of the
processor.
