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-igb-<version>.src.rpm

3. Build the binary RPM for the igb driver.

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

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

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

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

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

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

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

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

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

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

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

5. If an older version of igb.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 igb

Bring down the interfaces controlled by igb

	# ifconfig eth<n> down

Uninstall the existing active driver

	# modprobe -r igb

6. Install the new binary RPM package.

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

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

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

	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/<arch>/kmod-hp-igb-<flavor>-<version>.<arch>.rpm --nodeps 

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

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

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

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

For SLES, you must specify the module as igb while configuring the
network. The module can be specified in Hardware Details of Advanced
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 igb
	alias eth1 igb

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

	# lsmod

You should find igb 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.

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

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


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 <module name>
	insmod <module name> <optional parameter changes>
	ifconfig eth(x) up

Another step to reassign the IP address back to the device may be
required:

	ifconfig eth(x) <ip address>

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 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 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 igb driver uses the following symbols on 
RedHat EL5 Update 4 and Update 5 that is not on the whitelist:

ksym(dca_register_notify) 
ksym(dca3_get_tag)        
ksym(dca_unregister_notify) 
ksym(dca_remove_requester)
ksym(dca_add_requester) 
ksym(vlan_gro_receive) 
ksym(napi_gro_receive) 
ksym(napi_gro_flush) 
ksym(pci_disable_sriov) 
ksym(pci_enable_sriov)
ksym(pci_enable_msi) 
ksym(pci_enable_msix)
ksym(pci_disable_msi) 
ksym(pci_disable_msix)
