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: + + 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. + + 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. + +Support +======= + +For general information, go to the Intel support website at: + + http://support.intel.com + +If an issue is identified with the released source code on the supported +kernel with a supported adapter, email the specific information related to +the issue to linux.nics@intel.com. + + +License +======= + +This software program is released under the terms of a license agreement +between you ('Licensee') and Intel.
