-Identifying Your Adapter
-========================
+Supported Adapters
+==================
+
+To verify that your adapter is supported, find the board ID number on the
+adapter. Look for a label that has a barcode and a number in the format
+A12345-001. Match this to the list of numbers above.
For more information on how to identify your adapter, go to the Adapter &
Driver ID Guide at:

-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.
-
- After ethtool is installed, ethtool-copy.h must be copied and renamed to
- ethtool.h in your kernel source tree at <linux_kernel_src>/include/linux.
- Backup the original ethtool.h as needed before copying. The driver then
- must be recompiled in order to take advantage of the latest ethtool
- features.
-
- 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. NAPI is enabled
- or disabled based on the configuration of the kernel.
-
- See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.
