-To verify that your adapter is supported, find the board ID number on the

+========================
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 PRO/100 network driver for Linux, see:

+networking link on the left to search for your adapter:
http://downloadfinder.intel.com/scripts-df/support_intel.asp
+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.

InterruptThrottleRate
Valid Range: 100-100000 (0=off, 1=dynamic)
-Default Value: 1
+Default Value: 8000
This value represents the maximum number of interrupts per second the
controller generates. InterruptThrottleRate is another setting used in
interrupt moderation. Dynamic mode uses a heuristic algorithm to adjust
InterruptThrottleRate based on the current traffic load.
+Un-supported Adapters: InterruptThrottleRate is NOT supported by 82542, 82543
+ or 82544-based adapters.
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.
+ CAUTION: If you are using the Intel PRO/1000 CT Network Connection
+ (controller 82547), setting InterruptThrottleRate to a value
+ greater than 75,000, may hang (stop transmitting) adapters 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 InterruptThrottleRate is set no greater than 75,000 and is
+ not set to 0.
+ NOTE: When e1000 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:
+
+ insmod e1000.o 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

- This option enables NIC (Network Interface Card) hardware throttling
- during periods of extreme congestion. At the moment only a couple
- of device drivers support it (really only one -- tulip, a modified
- 8390 driver can be found at
- <ftp://ftp.tux.org/pub/net/ip-routing/fastroute/fastroute-8390.tar.gz>).
-
- Really, this option is applicable to any machine attached to a fast
- enough network, and even a 10 Mb NIC is able to kill a not very slow
- box, such as a 120MHz Pentium.
-
- However, do not say Y here if you did not experience any serious
- problems.
