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 doc
rpm. The doc 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 before proceding.

2. Install the source RPM package.

	# rpm -ivh hp-tg3-<version>.src.rpm

3. Build the binary RPM for the tg3 driver.

	RHEL 5:
	# rpmbuild -bb /usr/src/redhat/SPECS/hp-tg3.spec

	RHEL 6:
	# rpmbuild -bb ~/rpmbuild/SPECS/hp-tg3.spec

	SLES:
	# rpmbuild -bb /usr/src/packages/SPECS/hp-tg3.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-tg3.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-tg3.spec

4. Check for existence of a current version of the hp-tg3 package 
as follows:
	
	RHEL
	# rpm -q kmod-hp-tg3-<flavor> 

	SLES
	# rpm -q hp-tg3-kmp-<flavor>

	If an old version of the RPM package exists, it should be
	removed as follows.

	RHEL
	# rpm -e kmod-hp-tg3-<flavor>

	SLES
	# rpm -e hp-tg3-kmp-<flavor>

	Verify if the old hp-tg3 package has been removed as follows:

	RHEL
	# rpm -q kmod-hp-tg3-<kernel flavor>

	SLES
	# rpm -q hp-tg3-kmp-<kernel flavor>  

5. If an older version of tg3.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 tg3

Bring down the interfaces controlled by tg3

	# ifconfig eth<n> down

Uninstall the existing active driver

	# modprobe -r tg3

6. Install the new binary RPM package.

	RHEL 5
	# rpm -ivh \
	/usr/src/redhat/RPMS/<arch>/kmod-hp-tg3-<flavor>-<version>.<arch>.rpm 

	RHEL 6
	# rpm -ivh \
	~/rpmbuild/RPMS/<arch>/kmod-hp-tg3-<flavor>-<version>.<arch>.rpm 

	The modules are installed in the following directory:
	/lib/modules/<kernel_version>/extra/hp-tg3

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

	# rpm -ivh \
	/usr/src/redhat/RPMS/<arch>/kmod-hp-tg3-<flavor>-<version>.<arch>.rpm --nodeps 

	SLES
	# rpm -ivh RPMS/<arch>/hp-tg3-kmp-<version>-<flavor>.<arch>.rpm 

	The modules are installed in the following directory:
	/lib/modules/<kernel_version>/updates/hp-tg3

7.  Run "modinfo tg3 | grep version" and verify that the driver
version is latest

8.  Run "modprobe tg3" to install latest "tg3" 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.

10. 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 tg3
	alias eth1 tg3
	alias eth# tg3

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

11. Reboot the server or restart the network services. Upon reboot
the network should start with tg3 driver loaded

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

	# lsmod

You should find tg3 listed. Use ifconfig to bring up the network 
with the new driver:

	# ifconfig eth# up


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

	RHEL
	# rpm -e kmod-hp-tg3-<kernel flavor>

	SLES
	# rpm -e hp-tg3-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 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 tg3 packaged drivers uses the following symbols
on RedHat EL5 Update 3, Update 4 and Update 5 that are not on the whitelist:

Update 4
ksym(pci_enable_msi)
ksym(pci_disable_msi)

Update 3
ksym(pcie_set_readrq)
