Introduction
============
This file describes the Linux Ethernet driver for HP NC-Series Qlogic 
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 qlcnic 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 is a source rpm so it 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-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 qlcnic package as follows:
	
	RHEL
	# rpm -q kmod-hp-qlcnic-<flavor> 

	SLES
	# rpm -q hp-qlcnic-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-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. Install the new RPM package.  

	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.x 
	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

6.  After binary rpms are installed, run "modinfo qlcnic" and verify driver version 
is <drv_ver>

7.  Run "modprobe qlcnic" OR "insmod /lib/modules/<kernel_version>/extra/qlcnic/qlcnic.ko" 
to install "qlcnic" module


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

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

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


Limitations
===========
None


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 4 and Update 5 that are not on the whitelist:

ksym(pci_get_domain_bus_and_slot) 
ksym(pci_cleanup_aer_uncorrect_error_status)
ksym(pci_disable_pcie_error_reporting) 
ksym(pci_enable_pcie_error_reporting) 
ksym(napi_gro_flush)
