13 - Additional Configurations
20 This file describes the Linux* Base Driver for the Intel(R) PRO/100 Family of
21 Adapters, version 3.3.x. This driver supports 2.4.x and 2.6.x kernels.
23 Identifying Your Adapter
24 ========================
26 For more information on how to identify your adapter, go to the Adapter &
29 http://support.intel.com/support/network/adapter/pro100/21397.htm
31 For the latest Intel network drivers for Linux, refer to the following
32 website. In the search field, enter your adapter name or type, or use the
33 networking link on the left to search for your adapter:

37 Driver Configuration Parameters
38 ===============================
40 The default value for each parameter is generally the recommended setting,
41 unless otherwise noted.
43 Rx Descriptors: Number of receive descriptors. A receive descriptor is a data
44 structure that describes a receive buffer and its attributes to the network
45 controller. The data in the descriptor is used by the controller to write
46 data from the controller to host memory. In the 3.0.x driver the valid
47 range for this parameter is 64-256. The default value is 64. This parameter
48 can be changed using the command
50 ethtool -G eth? rx n, where n is the number of desired rx descriptors.
52 Tx Descriptors: Number of transmit descriptors. A transmit descriptor is a
53 data structure that describes a transmit buffer and its attributes to the
54 network controller. The data in the descriptor is used by the controller to
55 read data from the host memory to the controller. In the 3.0.x driver the
56 valid range for this parameter is 64-256. The default value is 64. This
57 parameter can be changed using the command
59 ethtool -G eth? tx n, where n is the number of desired tx descriptors.
61 Speed/Duplex: The driver auto-negotiates the link speed and duplex settings by
62 default. Ethtool can be used as follows to force speed/duplex.
64 ethtool -s eth? autoneg off speed {10|100} duplex {full|half}
66 NOTE: setting the speed/duplex to incorrect values will cause the link to
69 Event Log Message Level: The driver uses the message level flag to log events
70 to syslog. The message level can be set at driver load time. It can also be
73 ethtool -s eth? msglvl n
75 Additional Configurations
76 =========================
78 Configuring the Driver on Different Distributions
79 -------------------------------------------------
81 Configuring a network driver to load properly when the system is started is
82 distribution dependent. Typically, the configuration process involves adding
83 an alias line to /etc/modules.conf as well as editing other system startup
84 scripts and/or configuration files. Many popular Linux distributions ship
85 with tools to make these changes for you. To learn the proper way to
86 configure a network device for your system, refer to your distribution
87 documentation. If during this process you are asked for the driver or module
88 name, the name for the Linux Base Driver for the Intel PRO/100 Family of
91 As an example, if you install the e100 driver for two PRO/100 adapters
92 (eth0 and eth1), add the following to modules.conf:
99 In order to see link messages and other Intel driver information on your
100 console, you must set the dmesg level up to six. This can be done by
101 entering the following on the command line before loading the e100 driver:
105 If you wish to see all messages issued by the driver, including debug
106 messages, set the dmesg level to eight.
108 NOTE: This setting is not saved across reboots.
113 The driver utilizes the ethtool interface for driver configuration and
114 diagnostics, as well as displaying statistical information. Ethtool
115 version 1.6 or later is required for this functionality.
117 The latest release of ethtool can be found at:
118 http://sf.net/projects/gkernel.
120 NOTE: This driver uses mii support from the kernel. As a result, when
121 there is no link, ethtool will report speed/duplex to be 10/half.
123 NOTE: Ethtool 1.6 only supports a limited set of ethtool options. Support
124 for a more complete ethtool feature set can be enabled by upgrading
125 ethtool to ethtool-1.8.1.
127 Enabling Wake on LAN* (WoL)
128 ---------------------------
129 WoL is provided through the Ethtool* utility. Ethtool is included with Red
130 Hat* 8.0. For other Linux distributions, download and install Ethtool from
131 the following website: http://sourceforge.net/projects/gkernel.
133 For instructions on enabling WoL with Ethtool, refer to the Ethtool man
136 WoL will be enabled on the system during the next shut down or reboot. For
137 this driver version, in order to enable WoL, the e100 driver must be
138 loaded when shutting down or rebooting the system.
143 NAPI (Rx polling mode) is supported in the e100 driver.
145 See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.
