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 nx_nic 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 is a source rpm and requires a build environment setup for the build. Please refer to the "Build Environment Setup" section before proceding. 2. Install the source RPM package. #rpm -ivh hp-nx_nic-.src.rpm 3. Build the binary RPM for the hp-nx_nic and hp-nx_nic-tools package. RHEL 5: # rpmbuild -bb /usr/src/redhat/SPECS/hp-nx_nic.spec RHEL 6: # rpmbuild -bb ~/rpmbuild/SPECS/hp-nx_nic.spec SLES: # rpmbuild -bb /usr/src/packages/SPECS/hp-nx_nic.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-nx_nic.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-nx_nic.spec Note: This spec file will generate a KMOD/KMP driver pacakge and an additional hp-nx_nic-tools package. The tools package includes the firmware files necessary for the driver to work. The driver package depends on the tools package and one can't install the driver package with out it. 4. Check for the existence of a current version of the nx_nic package as follows: RHEL # rpm -q kmod-hp-nx_nic- SLES # rpm -q hp-nx_nic-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-nx_nic- SLES # rpm -e hp-nx_nic-kmp- Verify if the old hp-nx_nic package has been removed as follows: RHEL # rpm -q kmod-hp-nx_nic- SLES # rpm -q hp-nx_nic-kmp- After verifying removal of the driver package, remove corresponding tools package as follows # rpm -e hp-nx_nic-tools 5. Verify if an old version of nx_nic OR netxen_nic is loaded into the kernel and remove it as follows # lsmod | grep nx_nic OR # lsmod | grep netxen_nic Before removing the driver you will have to bring down the interfaces controlled by nx_nic or netxen_nic # ifconfig eth down Finally remove the driver # modprobe -r nx_nic OR # modprobe -r netxen_nic 6. Install an associated version of hp-nx_nic-tools before installing the driver package # rpm -ivh RPMS//hp-nx_tools--.rpm 7. Install the new binary driver RPM package. RHEL 5 # rpm -ivh \ /usr/src/redhat/RPMS//kmod-hp-nx_nic--..rpm RHEL 6 # rpm -ivh \ ~/rpmbuild/RPMS//kmod-hp-nx_nic--..rpm The modules are installed in the following directory: /lib/modules//extra/hp-nx_nic 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-nx_nic--..rpm --nodeps SLES # rpm -ivh RPMS//hp-nx_nic-kmp--..rpm The modules are installed in the following directory: /lib/modules//updates/hp-nx_nic 8. After binary rpms are installed, run "modinfo nx_nic" and verify the driver version 9. Run "modprobe nx_nic" to install latest "nx_nic" driver module Uninstalling the RPM Package =============================== The following command will uninstall the RPM. Red Hat # rpm -e kmod-hp-nx_nic- SLES # rpm -e hp-nx_nic-kmp- The following command uninstall the hp-nx_nic-tools package. Uninstall the driver package before executing the below step #rpm -e hp-nx_nic-tools Driver Settings ================= The following settings are the default and optional parameters for the NIC Speed: 10,0000 Mbps, full-duplex MTU: Default: 1500 Range : 0-8000 See the Examples section below on how to set the MTU TSO: Default: On See the Examples section below on how to change TSO The following optional parameters can be passed to the driver with the modprobe command. Note: See the Examples section below for an illustration on how to set the parameters. tx_desc Default: 1024 Range : 256-4096 (must be power of two) This sets the size of the command descriptor rings (tx) jumbo_desc Default: 1024 Range : 64-4096 (must be power of two) This sets the size of the receive ring for jumbo frames rdesc_10g Default: 32768 Range : 64-65536 (must be power of two) This sets the size of the receive ring for "normal" packets (10GbE ports) use_msi Default: Enable (1) Range: Disable (0) or Enable (1) This enables or disables MSI. Examples The following command illustrates how to set the optional parameters: # modprobe nx_nic tx_desc=2048 The following command illustrates how to set the MTU: # ifconfig eth mtu 8000 The following command illustrates how to change the TSO parameter: # ethtool -K eth tso off Driver Messages =============== The messages will be logged in the file /var/log/messages. Some Linux distributions may not display messages to the console. To set messages to display on the console, at the command line use the following to control the level at which messages will appear on the console. # dmesg -n 6 Most systems are set to level 6 by default. 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 only included 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 nx_nic packaged drivers uses the following symbols on RedHat EL5 Update 4 and Update 5 that are not on the whitelist: ksym(pci_enable_msi) ksym(pci_enable_msix) ksym(pci_disable_msi) ksym(pci_disable_msix) (C) Copyright 2011 Hewlett-Packard Development Company, L.P.
