Table of Contents ================= Introduction Packaging Kernel Source Code Setup Installing Source RPM Package Statistics Limitations Introduction ============ This file describes the Linux driver for the HP Server Adapters mentioned in the PRODUCTS AFFECTED section. After installation additional information can be found in the MAN page for e100, and in the RELEASE.TXT file located at: For Red Hat: /usr/share/doc/e100-/README For SuSE: /usr/share/doc/packages/e100/README User guides and additional HP Network Adapter information can be found at: http://www.compaq.com/support/networking/nics/index.html Packaging ========= The driver is released in a source RPM format. The file name for the package is e100-.src.rpm and is dependent on the kernel source code. If you have not installed the kernel source code and/or setup the source tree on your Linux system please see the "Kernel Source Code Setup" section below. The steps in the following section (kernel Source Code setup) and "Installing the Source RPM Package" have to be executed first time a new kernel is booted. Kernel Source Code Setup ======================== The e100 driver requires the presence of the kernel source code and configuring the kernel source before building the e100 driver. The following steps need to be done once for each kernel that is booted. For example, if the current kernel is UP (uni-processor) and an SMP (symmetrical-multi-processor) kernel is booted, these steps must be performed again to configure the kernel source for SMP before building the e100 driver for the SMP kernel. Red Hat installation: If the /usr/src/linux- directory does not exist install the kernel source code per Red Hat instructions. Once installed, follow the commands listed below to configure the kernel source to match the running kernel. For Red Hat Linux 8.0 Professional: # cd /usr/src/linux- # make mrproper # make -e KERNELRELEASE=`uname -r` oldconfig # make -e KERNELRELEASE=`uname -r` dep For all other Red Hat Linux distributions: # cd /usr/src/linux- # make mrproper # make oldconfig # make dep SuSE installation: If the /usr/src/linux- directory does not exist please install the kernel source code per SuSE instructions. Once installed, please follow the commands listed below to setup the kernel source tree. # cd /usr/src/linux-.SuSE # cp /boot/vmlinuz.config .config # cp /boot/vmlinuz.version.h include/linux/version.h # cp /boot/vmlinuz.autoconf.h include/linux/autoconf.h # make oldconfig # make dep Installing Source RPM Package ============================= 1. This package requires the kernel source code as well as setting up the source tree. Verify the source code /usr/src/linux- directory exist. # cd /usr/src/linux- If the kernel source code is not present then please refer to the "Kernel Source Code Setup" section. 2. Install the source RPM package. # rpm -ivh e100-.src.rpm 3. Build the binary RPM for the e100 driver. Red Hat Installation: # cd /usr/src/redhat # rpmbuild -bb SPECS/e100.spec SuSE Installation: # cd /usr/src/packages # rpm -bb SPECS/e100.spec If you get an error during the build process, please refer to the "Kernel Source Code Setup" section to correctly setup the source tree. 4. Install the new RPM package. This installs the e100 driver and man page. Note to Red Hat users: The e100 driver installed by this RPM supersedes the default eepro100 driver. The existing eepro100 driver will have to be removed prior to installing the e100 driver. This e100 driver has been tested and approved by HP. To rename the existing eepro100 driver, use the following command. # mv /lib/modules//kernel/drivers/net/eepro100.o /lib/modules//kernel/drivers/net/eepro100.o.old # rpm -ivh RPMS/i386/e100-.i386.rpm If an older version of e100 already exists or a conflict occurs, please use the "force" command as shown below. # rpm -ivh RPMS/i386/e100-.i386.rpm --force The e100.o driver will be installed in the following path: Red Hat 8.0 /lib/modules//kernel/drivers/net/e100/e100.o Red Hat AS 2.1 /lib/modules//kernel/drivers/net/e100.o SuSE /lib/modules//kernel/drivers/net/e100.o 5. Configure your network setting and address. You may need to refer to your Linux vendor documentation. Other helpful network configuration tools such a "yast" in SLES 7 or "linuxconf" in Red Hat exist for easy configuration. 6. Ensure that the /etc/modules.conf file is configured similar to the example listed below. The example below is presented as if more than one adapter is present. If so, one eth# instance should exist for each ethernet port. View the modules.conf man page for more information. alias eth0 e100 alias eth1 e100 7. You can now reboot your server. Upon reboot the network should start with the e100 driver loaded and the correct network configuration. To verify that the e100 driver is loaded use the following command. # lsmod If e100 is listed then the e100 driver is loaded. You can also verify that the correct e100 driver is loaded through any of the following methods. Please note that version of the driver loaded should be same as that of the package version. 1. Look for driver load messages in the system log. #dmesg | grep Intel You should see messages of the following type, Intel(R) PRO/100 Network Driver - version x.x.x 2. Check the ethernet adapter driver information through the /proc interface. #grep Driver_Version /proc/net/PRO_LAN_Adapters/*.info Statistics ========== Detailed statistics, configuration information and driver information can be viewed by: # more /proc/net/PRO_LAN_adapters/eth#.info. Limitations =========== In order to work around a panic occuring during high network traffic, the tasklet support has been disabled in this driver. This could lead to packets getting dropped at very high network traffic Some Linux distributions may not add the default route back to a specified network device when a network stop/start command is used. Use the route command to add the default router back to the network device. Some Linux distributions may not add the default assigned IP address back to a specified network device when using the following: ifconfig eth(x) down rmmod insmod ifconfig eth(x) up Another step to reassign the IP address back to the device may be required: ifconfig eth(x) Some Linux distributions may add multiple IP addresses with the same system name in the /etc/hosts file when configuring multiple network devices.
