ENHANCEMENTS/FIXES: 1) KMP is now built for each SLES kernel flavor 2) RHEL 5 update 6 support has been added Table of Contents ================= Introduction Packaging Build Environment Setup Installing the RPM Package Uninstalling the RPM Limitations Caveats Introduction ============ This file describes the Linux Ethernet driver for HP NC-Series Intel Adapters mentioned in the PRODUCTS AFFECTED section of this document. User guides and additional HP Network Adapter information can be found at: http://h18004.www1.hp.com/products/servers/networking/index-nic.html Packaging ========= The driver is released in Kernel Module Package (KMP) source RPM format. KMP packages use macros that determine kernel flavors for which binary packages need to be built based on spec file rules. It is important to have the right build environment set up in order to compile a binary RPM from the source package. See "Build Environment Setup" section below. Build Environment Setup ======================== The igb package requires the presence of some packages that provide the right build environment. These packages provide kernel headers, makefiles and symbol files, though the last one is suggested only on SLES distributions. RHEL installation: 1. redhat-rpm-config package 2. kernel-devel- package 3. kernel--devel- package Eg: kernel-2.6.18.92.el5 requires kernel-devel-2.6.18-92.el5 kernel-PAE-2.6.18.92.el5 requires kernel-PAE-devel-2.6.18-92.el5 See the "Caveats" section below for more details. SLES Installation: 1. kernel-source- package 2. kernel-syms- package 3. SLES11 requires kernel--devel- package as well Installing the RPM Package ============================= 1. This package requires a build environment. Please refer to the "Build Environment Setup" Section before proceding to the next step. 2. Install the source RPM package. # rpm -ivh hp-igb-.src.rpm 3. Build the binary RPM for the igb driver. RHEL 5: # rpmbuild -bb /usr/src/redhat/SPECS/hp-igb.spec RHEL 6: # rpmbuild -bb ~/rpmbuild/SPECS/hp-igb.spec SLES: # rpmbuild -bb /usr/src/packages/SPECS/hp-igb.spec If you get an error during the build process, refer to the "Build Environment Setup" section. NOTE: One can build binary RPM for a specfic kernel flavor as follows: # rpmbuild -bb SPECS/hp-igb.spec --define "KVER " NOTE: RHEL 5 x86 installations require the "--target" switch when building on Intel compatible machines. Please see the "Caveats" section below for more details. # rpmbuild --target=i686 -bb /usr/src/redhat/SPECS/hp-igb.spec 4. Check for the existence of a current version of the igb package as follows: RHEL # rpm -q kmod-hp-igb- SLES # rpm -q hp-igb-kmp- If an old version of the package exists, the RPM package should be removed. Remove the corresponding tools package before removing driver package. RHEL # rpm -e kmod-hp-igb- SLES # rpm -e hp-igb-kmp- Verify if the old hp-igb package has been removed as follows: RHEL # rpm -q kmod-hp-igb- SLES # rpm -q hp-igb-kmp- 5. Install the new binary RPM package. RHEL 5 # rpm -ivh \ /usr/src/redhat/RPMS//kmod-hp-igb--..rpm RHEL 6 # rpm -ivh \ ~/rpmbuild/RPMS//kmod-hp-igb--..rpm The modules are installed in the following directory: /lib/modules//extra/hp-igb Note: The "--nodeps" switch is required when installing on RHEL 5.5. See "Caveats" section below for more details. # rpm -ivh \ /usr/src/redhat/RPMS//kmod-hp-igb--..rpm --nodeps SLES # rpm -ivh RPMS//hp-igb-kmp--..rpm The modules are installed in the following directory: /lib/modules//updates/hp-igb 6. Configure your network setting and address. You may need to refer to Linux vendor documentation. Helpful network configuration tools such as "yast2" in SLES or linuxconf/redhat-config-network/netconfig in Red Hat exist for easy configuration. For SLES, user may have to specify the module as igb while configuring the network. The module can be specified in Hardware Details of Advanced configuration 7. 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. Refer to the modules.conf man page for more information. alias eth0 igb alias eth1 igb For SLES, the configuration file is /etc/modprobe.conf or /etc/modprobe.conf.local 8. You can now reboot your server or restart the network services. Upon reboot the network should start with the igb driver loaded To verify that the igb driver is loaded use the following command. # lsmod If igb is listed then the igb driver is loaded. You can also verify that the correct igb driver is loaded through any of the following methods. Note that version of the driver loaded should be same as that of the package version. A. Look for driver load messages in the system log. #dmesg | grep Intel You should see messages of the following type, Intel(R) PRO/1000 Network Driver - version x.x.x B. Check the /var/log/messages file for a similar message as indicated in method A. Note: To load the driver from command line use 'modprobe' instead of 'insmod'. Refer to the man pages for lsmod, ifconfig, rmmod, insmod, modprobe, modules.conf and modprobe.conf for more detailed information. Uninstalling the RPM ==================== The following command will uninstall the RPM. Red Hat # rpm -e kmod-hp-igb- SLES # rpm -e hp-igb-kmp- Limitations =========== 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. Caveats ======== 1. The rpmbuild will fail the dependency check when building the non-base (xen,pae,etc) kernel when the kernel-devel package is not installed. Example: If the OS installed only the PAE kernel, then the user would need to install the kernel-pae-devel and kernel-devel packages. 2. The use of a "--target" switch is required so that rpmbuild does not try to find an i386 kernel on the system. If the "--target" switch is not used then the build will fail with bizarre messages stating that specific kernel packages are not installed on the machine yet those packages do not exist. 3. The rpmbuild will fail if the redhat-rpm-config package is not installed because it cannot resolve the %kernel_module_package_buildreqs macro. The error will be similar to the following: error: line xx: Dependency tokens must begin with alpha-numeric,'_'or'/': Build Requires: %kernel_module_package_buildreqs 4. RPM uses KMP packaging dependency data to ensure the dependencies are met before installing the binary RPM. Red Hat maintains a whitelist of kernel symbols which RPM uses to validate against the KMP binaries. Some symbols may be in the kernel but not on the whitelist which results in a failed binary RPM install. The user will need to use the "--nodeps" switch when installing the binary. The igb driver uses the following symbols on RedHat EL5 Update 4 and Update 5 that is not on the whitelist: ksym(dca_register_notify) ksym(dca3_get_tag) ksym(dca_unregister_notify) ksym(dca_remove_requester) ksym(dca_add_requester) ksym(vlan_gro_receive) ksym(napi_gro_receive) ksym(napi_gro_flush) ksym(pci_disable_sriov) ksym(pci_enable_sriov) ksym(pci_enable_msi) ksym(pci_enable_msix) ksym(pci_disable_msi) ksym(pci_disable_msix) (C) Copyright 2002, 2003 - 2011 Hewlett-Packard Development Company, L.P.
