In This Release
|
|
===============
|
|
|
|
This file describes the Linux* Base Driver for the Intel(R) PRO/100 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/100 adapter.
|
|
|
|
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
|
|
|
|
|
|
Identifying Your Adapter
|
|
========================
|
|
|
|
For more information on how to identify your adapter, go to the Adapter &
|
|
Driver ID Guide at:
|
|
|
|
http://support.intel.com/support/network/adapter/pro100/21397.htm
|
|
|
|
For the latest Intel network drivers for Linux, refer to the following
|
|
website. In the search field, enter your adapter name or type, or use the
|
|
networking link on the left to search for your adapter:
|
|

|
|
|
|
Driver Configuration Parameters
|
|
===============================
|
|
|
|
The default value for each parameter is generally the recommended setting,
|
|
unless otherwise noted.
|
|
|
|
Rx Descriptors: Number of receive descriptors. A receive descriptor is a data
|
|
structure that describes a receive buffer and its attributes to the network
|
|
controller. The data in the descriptor is used by the controller to write
|
|
data from the controller to host memory. In the 3.x.x driver the valid range
|
|
for this parameter is 64-256. The default value is 64. This parameter can be
|
|
changed using the command:
|
|
|
|
ethtool -G eth? rx n, where n is the number of desired rx descriptors.
|
|
|
|
Tx Descriptors: Number of transmit descriptors. A transmit descriptor is a data
|
|
structure that describes a transmit buffer and its attributes to the network
|
|
controller. The data in the descriptor is used by the controller to read
|
|
data from the host memory to the controller. In the 3.x.x driver the valid
|
|
range for this parameter is 64-256. The default value is 64. This parameter
|
|
can be changed using the command:
|
|
|
|
ethtool -G eth? tx n, where n is the number of desired tx descriptors.
|
|
|
|
Speed/Duplex: The driver auto-negotiates the link speed and duplex settings by
|
|
default. Ethtool can be used as follows to force speed/duplex.
|
|
|
|
ethtool -s eth? autoneg off speed {10|100} duplex {full|half}
|
|
|
|
NOTE: setting the speed/duplex to incorrect values will cause the link to
|
|
fail.
|
|
|
|
Event Log Message Level: The driver uses the message level flag to log events
|
|
to syslog. The message level can be set at driver load time. It can also be
|
|
set using the command:
|
|
|
|
ethtool -s eth? msglvl n
|
|
|
|
|
|
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
|
|
PRO/100 Family of Adapters is e100.
|
|
|
|
As an example, if you install the e100 driver for two PRO/100 adapters
|
|
(eth0 and eth1), add the following to modules.conf or modprobe.conf:
|
|
|
|
alias eth0 e100
|
|
alias eth1 e100
|
|
|
|
Viewing Link Messages
|
|
---------------------
|
|
In order to see link messages and other Intel driver information on your
|
|
console, you must set the dmesg level up to six. This can be done by
|
|
entering the following on the command line before loading the e100 driver:
|
|
|
|
dmesg -n 8
|
|
|
|
If you wish to see all messages issued by the driver, including debug
|
|
messages, set the dmesg level to eight.
|
|
|
|
NOTE: This setting is not saved across reboots.
|
|
|
|
|
|
Ethtool
|
|
-------
|
|
|
|
The driver utilizes the ethtool interface for driver configuration and
|
|
diagnostics, as well as displaying statistical information. Ethtool
|
|
version 1.6 or later is required for this functionality.
|
|
|
|
The latest release of ethtool can be found from
|
|
http://sourceforge.net/projects/gkernel.
|
|
|
|
NOTE: Ethtool 1.6 only supports a limited set of ethtool options. Support
|
|
for a more complete ethtool feature set can be enabled by upgrading
|
|
ethtool to ethtool-1.8.1.
|
|
|
|
|
|
Enabling Wake on LAN* (WoL)
|
|
---------------------------
|
|
WoL is provided through the Ethtool* utility. Ethtool is included with Red
|
|
Hat* 8.0. For other Linux distributions, download and install Ethtool from
|
|
the following website: http://sourceforge.net/projects/gkernel.
|
|
|
|
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 e100 driver must be
|
|
loaded when shutting down or rebooting the system.
|
|
|
|
|
|
NAPI
|
|
----
|
|
|
|
NAPI (Rx polling mode) is supported in the e100 driver.
|
|
|
|
See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.
|
|
|
|
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
|
|
|
|
(1) 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), or
|
|
|
|
(2) installing the interfaces in separate broadcast domains (either
|
|
in different switches or in a switch partitioned to VLANs).
|
|
