Introduction
============
This file describes the Linux Ethernet driver for HP NC-Series ServerEngines 
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 be2net 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-<kernel_version> package
	3. kernel-<flavor>-devel-<kernel_version> 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-<kernel_version> package
	2. kernel-syms-<kernel_version> package
	3. SLES11 requires kernel-<flavor>-devel-<kernel_version> package as well


Installing the RPM Package
=============================
1. This package requires a build environment.  Please refer to the 
"Build Environment Setup" Section before proceeding to the next step.

2. Install the source RPM package.

	# rpm -ivh hp-be2net-<version>.src.rpm

3. Build the binary RPM for be2net driver.

	RHEL 5:
	# rpmbuild -bb /usr/src/redhat/SPECS/hp-benet.kmp.spec

	RHEL 6:
	# rpmbuild -bb ~/rpmbuild/SPECS/hp-benet.kmp.spec

	SLES:
	# rpmbuild -bb /usr/src/packages/SPECS/hp-benet.kmp.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-be2net.kmp.spec --define "KVER <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-benet.kmp.spec

4. Check for the existence of a current version of the be2net package as follows:
	
	RHEL
	# rpm -q kmod-hp-be2net-<flavor> 

	SLES
	# rpm -q hp-be2net-kmp-<flavor>

	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-be2net-<flavor>

	SLES
	# rpm -e hp-be2net-kmp-<flavor>

	Verify if the old hp-be2net package has been removed as follows:

	RHEL
	# rpm -q kmod-hp-be2net-<kernel flavor>

	SLES
	# rpm -q hp-be2net-kmp-<kernel flavor>  

5. Install the new binary RPM package.

	RHEL 5
	# rpm -ivh \
	/usr/src/redhat/RPMS/<arch>/kmod-hp-be2net-<flavor>-<version>.<arch>.rpm 

	RHEL 6
	# rpm -ivh \
	~/rpmbuild/RPMS/<arch>/kmod-hp-be2net-<flavor>-<version>.<arch>.rpm 

	The modules are installed in the following directory:
	/lib/modules/<kernel_version>/extra/hp-be2net

	Note:  The "--nodeps" switch is required when installing to RHEL 5.4 and 
	RHEL 5.5. See the "Caveats" section below for more details.

	# rpm -ivh \
	/usr/src/redhat/RPMS/<arch>/kmod-hp-be2net-<flavor>-<version>.<arch>.rpm --nodeps 

	SLES
	# rpm -ivh RPMS/<arch>/hp-be2net-kmp-<version>-<flavor>.<arch>.rpm 

	The modules are installed in the following directory:
	/lib/modules/<kernel_version>/updates/hp-be2net

6. Configure your network setting and address. You may need to refer to your 
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.

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 be2net
	alias eth1 be2net

For SLES, the configuration file is /etc/modprobe.conf or 
/etc/modprobe.conf.local

Note: If the above entry does not exist, add it in the configuration file.

8. Reboot the server or restart the network services. Upon reboot 
the network should start with be2net driver loaded  

To verify that the driver is loaded, use the following command.

	# lsmod

You should find be2net listed.


Driver Messages
===============
The following are the most common sample messages that may be logged in the file
/var/log/messages. Some Linux distributions may not display messages to 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.


Uninstalling the RPM Package
=============================
The following command will uninstall the RPM.

	RHEL
	# rpm -e kmod-hp-be2net-<kernel flavor>

	SLES
	# rpm -e hp-be2net-kmp-<kernel flavor>


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 these pacakges 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'/': 
BuildRequires: %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 be2net packaged drivers uses the following symbols on Red Hat EL 5 
Update 4 and Update 5 that are not on the whitelist:

ksym(pci_enable_msi) 
ksym(pci_disable_msi)
