Linux Driver for the Intel(R) PRO/100 Family of Server Adapters ================================================================ This file describes the Intel(R) PRO/100 driver for the Linux operating system. This package includes the source code for a Linux driver for the Intel PRO/100 Server and Desktop adapters. This driver is known to build properly on 2.2.x kernels through 2.2.18 and on the 2.4.0 kernel. Intel performed testing on PCs with Intel processors with kernels 2.2.16, 2.2.18 and 2.4.0. Intel(R) Itanium(TM) use is beta only. The Intel PRO/100 driver is only supported as a loadable module at this time. Intel is not supplying patches against the kernel source to allow for static linking of the driver. Please refer to the documentation supplied with your Intel PRO/100 adapter to answer any questions related to hardware requirements. All hardware requirements listed apply to use with Linux. Supported Adapters ================== This driver supports the following Intel network adapters. Name Board numbers Intel(R) PRO/100+ Server Adapter 729757-xxx Intel(R) PRO/100+ PCI Adapter 668081-xxx, 689661-xxx Intel(R) PRO/100+ Management Adapter 691334-xxx, 701738-xxx, 721383-xxx Intel(R) PRO/100 S Management Adapter 748566-xxx, 748564-xxx Intel(R) PRO/100 S Advanced Management Adapter 747842-xxx, 745171-xxx Intel(R) PRO/100+ Dual Port Server Adapter 714303-xxx, 711269-xxx, A28276-xxx Intel(R) PRO/100+ PCI Server Adapter 710550-xxx Intel(R) PRO/100 S Server Adapter 748568-xxx, 748565-xxx Intel(R) PRO/100 VE Desktop Adapter A10386-xxx, A10725-xxx, A23801-xxx Intel(R) PRO/100 VM Desktop Adapter A14323-xxx, A19725-xxx, A23801-xxx, A22220-xxx, A23796-xxx Intel(R) PRO/100 S Desktop Adapter 748592-xxx, A12167-xxx, A12318-xxx, A12317-xxx, A12165-xxx, 751767-xxx Intel(R) PRO/100 S Server Adapter A10563-xxx, A12171-xxx, A12321-xxx, A12320-xxx, A12170-xxx, 752438-xxx To verify 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 of 123456-001 (six digits hyphen 3 digits). 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: http://support.intel.com/support/network/adapter/pro100/21397.htm Building and Installation ========================= Note: For the build to work properly it is important that the currently running kernel MATCH the version and configuration of the installed kernel sources. Also if you have just recompiled your kernel, please reboot. 1. Move the base driver tarball to the directory of your choice. Example is using /home/username/e100 or /usr/local/src/e100 2. untar/unzip archive tar xfz e100-x.x.x.tar.gz 3. Change to the driver src directory cd e100-x.x.x/src/ 4. Compile the driver module make install The binary will be installed as: /lib/modules/[KERNEL_VERSION]/net/e100.o 5. Install the module insmod e100 6. ifconfig eth# where # is interface number 7. Verify interface works ping To build a binary RPM* package of this driver run 'rpm -tb '. Replace with the specific file name of driver. Basic Configuration =================== Once the driver has been installed it can be loaded by running 'modprobe e100'. This will create a new Ethernet device. For example, if no other Ethernet drivers are loaded the Intel PRO/100 will be called eth0. An interface can be activated and assigned an IP address by running: `ifconfig ethX yyy.yyy.yyy.yyy' where ethX is the Ethernet device and yyy.yyy.yyy.yyy is the IP address. Command Line Parameters ==================== The following parameters are used by entering them on the command line with the modprobe (or insmod) command. For example, with two Intel PRO/100 PCI cards, entering: modprobe e100 TxDescriptors=32,128 will load the e100 driver with 32 TX resources for the first card and 128 TX resources for the second card. This configuration will favor the second card. The driver supports up to 16 cards concurrently. TxDescriptors Valid Range: 17-1024 Default Value: 64 This value is the number of transmit descriptors allocated by the driver. Increasing this value will allow the protocol stack to queue more transmits at the driver level. Maximum for Intel Itanium is 64. RxDescriptors Valid Range: 8-1024 Default Value: 64 This value is the number of receive descriptors allocated by the driver. Increasing this value will allow the driver to buffer more incoming packets before the driver is required to service an interrupt. Maximum for Intel Itanium is 64. XsumRX (Nic dependent, Intel Itanium with 82550 based adapters only) Valid Range: 0-1 Default Value: 1 1 turns on receive TCP/UDP checksum offload 0 turns off receive TCP/UDP checksum offload Turning this parameter on will turn on receive checksum offloading for TCP/UDP packets if the hardware supports this feature. e100_speed_duplex Valid Range: 0-4 Default Value: 0 example usage: insmod e100.o e100_speed_duplex=4,4 (for two cards) 0 indicates autodetection for both speed and duplex mode 1 indicates a speed of 10Mbps and a duplex mode of half 2 indicates a speed of 10Mbps and a duplex mode of full 3 indicates a speed of 100Mbps and a duplex mode of half 4 indicates a speed of 100Mbps and a duplex mode of full Additional Configuration ======================== Configuring a network driver to load properly when the system is started is distribution dependent. Typically it involves adding an alias line to /etc/conf.modules 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. Refer to your distribution documentation to learn the proper way to configure a network device for your system. If during this process you are asked for the driver or module name, the driver name for the Intel PRO/100 is 'e100'. Support ======= For general information and peer to peer support go to the forum at: http://support.intel.com/newsgroups/netwadap.htm Read the forum charter, legal information, and posting guidelines before entering the forum. This forum will post new information regarding the driver as it becomes available.
