Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

In This Release
|
|
===============
|
|
|
|
This file describes the Linux* Base Driver for the Intel(R) PRO/100 Family of
|
|
Adapters, version 3.3.x. This driver supports 2.4.x and 2.6.x kernels.
|
|
|
|
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 3.0.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 3.0.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 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:
|
|
|
|
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 at:
|
|
http://sf.net/projects/gkernel.
|
|
|
|
NOTE: This driver uses mii support from the kernel. As a result, when
|
|
there is no link, ethtool will report speed/duplex to be 10/half.
|
|
|
|
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.
