+Identifying Your Adapter
+========================
 
 For more information on how to identify your adapter, go to the Adapter & 
 Driver ID Guide at:

+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.
