Introduction
============
This file describes how to build and install the Ethernet driver
for network adapters mentioned in the PRODUCTS AFFECTED section.
Additional information for the Ethernet drivers can be found in
the driver man page which gets installed on installing the tools
rpm. The tools rpm gets built along with the KMP binary rpm.

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
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 source package. See "Build Environment Setup"
section below for more details.


Build Environment Setup
========================
This package requires the presence of certain other packages that provide
the right build environment to enable building a KMP binary rpm from the
source rpm. These packages provide kernel headers, makefiles and symbol
files. Please ensure that the following are installed:

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
	   in addition to the above two mentioned


Installing the RPM Package
=============================
1. This package requires a specific build environment. Please refer the
"Build Environment Setup" section above before proceeding.

2. Install the source RPM package.

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

3. Build the binary RPM for the qlcnic package.

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

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

	SLES:
	# rpmbuild -bb /usr/src/packages/SPECS/hp-qlcnic.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-qlcnic.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-qlcnic.spec

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

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

	If an old version of the RPM package exists, it should be
	removed as follows. Remove the corresponding tools package 
	before removing the driver package itself.

	RHEL
	# rpm -e kmod-hp-qlcnic-<flavor>

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

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

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

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

5. If an older version of qlcnic.ko is loaded into the kernel, remove
it as follows.

Note: If you are installing the package over network you may want to be
careful. It is not absolutely necessary to remove the modules. This step
is necessary if you are doing the upgrade on the physical console and
you intend to see the new drivers taking over immediately

	# lsmod | grep qlcnic

Bring down the interfaces controlled by qlcnic

	# ifconfig eth<n> down

Uninstall the existing active driver

	# modprobe -r qlcnic

6. Install the new binary RPM package. This installs the qlcnic driver

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

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

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

	Note:  The "--nodeps" switch is required when installing on 
	RHEL 5.6, 5.7 and 5.8. See "Caveats" section below for more
	details.

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

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

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

7.  Run "modinfo qlcnic | grep version" and verify that the driver 
version is latest

8.  Run "modprobe qlcnic" to install latest "qlcnic" driver module

9. 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.


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

	Red Hat
	# rpm -e kmod-hp-qlcnic-<kernel flavor>

	SLES
	# rpm -e hp-qlcnic-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 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 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 qlcnic packaged drivers uses the following symbols on RedHat EL5 
Update 6 and Update 7 that are not on the whitelist:

ksym(pci_reset_function)
ksym(kobject_uevent_env)
ksym(pci_ioremap_bar)
