Linux* Base Driver for the Attansic(R) L2 Fast Ethernet Adapter ========================================================================== Contents ======== - In This Release - Building and Installation - Command Line Parameters - Additional Configurations - Known Issues - Support In This Release =============== This file describes the Linux* Base Driver for the Attansic(R) L2 Fast Ethernet Adapter, version 1.0.x. This driver supports the 2.4.x and 2.6.x kernels. This driver is only supported as a loadable module at this time. Attansic is not supplying patches against the kernel source to allow for static linking of the driver. For questions related to hardware requirements, refer to the documentation supplied with your Attansic(R) adapter. All hardware requirements listed apply to use with Linux. Building and Installation ========================= To build a binary RPM* package of this driver, run 'rpmbuild -tb <filename.tar.gz>'. Replace <filename.tar.gz> with the specific filename of the driver. NOTE: For the build to work properly, the currently running kernel MUST match the version and configuration of the installed kernel sources. If you have just recompiled the kernel reboot the system now. RPM functionality has only been tested in Red Hat distributions. 1. Move the base driver tar file to the directory of your choice. For example, use /home/username/atl2 or /usr/local/src/atl2. 2. Untar/unzip archive: tar zxf atl2-x.x.x.tar.gz 3. Change to the driver src directory: cd atl2-x.x.x/src/ 4. Compile the driver module: make install The binary will be installed as: /lib/modules/<KERNEL VERSION>/kernel/drivers/net/atl2.[k]o The install locations listed above are the default locations. They might not be correct for certain Linux distributions. For more information, see the ldistrib.txt file included in the driver tar. 5. Install the module: insmod atl2 <parameter>=<value> 6. Assign an IP address to the interface by entering the following, where x is the interface number: ifconfig ethx <IP_address> 7. Verify that the interface works. Enter the following, where <IP_address> is the IP address for another machine on the same subnet as the interface that is being tested: ping <IP_address> Command Line Parameters ======================= If the driver is built as a module, the following optional parameters are used by entering them on the command line with the modprobe or insmod command using this syntax: modprobe atl2 [<option>=<VAL1>,<VAL2>,...] insmod atl2 [<option>=<VAL1>,<VAL2>,...] For example, with two L001 PCIE adapters, entering: insmod atl2 TxMemSize=80,128 loads the atl2 driver with 8KB TX memory for the first adapter and 10KB TX memory for the second adapter. The default value for each parameter is generally the recommended setting, unless otherwise noted. NOTES: A descriptor describes a data buffer and attributes related to the data buffer. This information is accessed by the hardware. MediaType Valid Range: 0-4 0 - auto-negotiate at all supported speeds 1 - only link at 100Mbps Full Duplex *** for Fast Ethernet Fiber PCI-Express Bus Adapter only use. *** 2 - only link at 100Mbps Half Duplex 3 - only link at 10Mbps Full Duplex 4 - only link at 10Mbps Half Duplex Default Value: 0 MediaType forces the line speed/duplex to the specified value in megabits per second(Mbps). If this parameter is not specified or is set to 0 and the link partner is set to auto-negotiate, the board will auto-detect the correct speed. IntModTimer Valid Range: 50-65000 Default Value: 100 This value represents the minmum interval between interrupts controller generated. RxMemBlock Valid Range: 16-512 Default Value: 64 This value is the number of receice memory block allocated by the driver. Increasing this value allows the driver to buffer more incoming packets. Each memory block is 1536 bytes. NOTE: Depending on the available system resources, the request for a higher number of receive descriptors may be denied. In this case, use a lower number. TxMemSize Valid Range: 4-64 Default Value: 8 This value is the number KB of transmit memory allocated by the driver. Increasing this value allows the driver to queue more transmits. NOTE: Depending on the available system resources, the request for a higher number of transmit descriptors may be denied. In this case, use a lower number. FlashVendor Valid Range: 0-2 Default Value: 0 This value standards on vendor of spi flash used by the adapter. 0 for Atmel, 1 for SST, 2 for ST 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 Attansic L2 is atl2 As an example, if you install the atl2 driver for two L2 adapters (eth0 and eth1) and set the speed and duplex to 10full and 100half, add the following to modules.conf: alias eth0 atl2 alias eth1 atl2 options atl2 Speed=10,100 Duplex=2,1 Viewing Link Messages --------------------- Link messages will not be displayed to the console if the distribution is restricting system messages. In order to see network driver link messages on your console, set dmesg to eight by entering the following: dmesg -n 8 NOTE: This setting is not saved across reboots. Known Issues ============ NOTE: For distribution-specific information, see the ldistrib.txt file included in the driver tar. Driver Compilation ------------------ When trying to compile the driver by running make install, the following error may occur: "Linux kernel source not configured - missing version.h" To solve this issue, create the version.h file by going to the Linux source tree and entering: make include/linux/version.h.

After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
