The driver may not compile on kernelsolder than 2.4.24. Testing is concentrated on i386 and x86_64 architectures.Only limited testing has been done on some other architectures.Minor changes to some source files and Makefile may be needed on somekernels.Additionally, the Makefile will not compile the cnic driver on kernelsolder than 2.6.16. iSCSI offload is only supported on 2.6.16 and newerkernels. FCoE offload is only supported on 2.6.32 and newer kernels. Packaging=========The driver is released in two packaging formats: source RPM and compressed tarformats. The file name for the source RPM is:netxtreme2-<version>.src.rpmThe file name for the tar archive is:netxtreme2-<version>.tar.gz.Identical source files to build the drivers are included in both packages.Following is a list of files included -a) netxtreme2-<version>.src.rpm - NetXtreme II L2/cnic/bnx2fc/libfc/libfcoe  driver source RPMb) netxtreme2-<version>.tar.gz - tar zipped NetXtreme II  L2/cnic/bnx2fc/libfc/libfcoe driver sourcec) INSTALL.TXT - This filed) README.<driver>.TXT - driver specific readme instructions,   where driver is bnx2, bnx2x, bnx2i, bnx2fc.e) RELEASE.<driver>.TXT - release information text providing list of bug fixes  and enhancement for each driver.Installing Source RPM Package=============================The following are general guidelines for installing the driver.1. Install the source RPM package:   rpm -ivh netxtreme2-<version>.src.rpm2. CD to the RPM path and build the binary driver for your kernel:   cd /usr/src/{redhat,OpenLinux,turbo,packages,rpm ..} (For RHEL 6.0 and above, cd ~/rpmbuild )   rpm -bb SPECS/netxtreme2.specor   rpmbuild -bb SPECS/netxtreme2.spec (for RPM version 4.x.x)Note that the RPM path is different for different Linux distributions.The driver will be compiled for the running kernel by default. To buildthe driver for a kernel different than the running one, specify thekernel by defining it in KVER:   rpmbuild -bb SPECS/netxtreme2.spec --define "KVER <kernel version>"where <kernel version> in the form of 2.x.y-z is the version of anotherkernel that is installed on the system.3. Install the newly built package (driver and man page):   rpm -ivh RPMS/<arch>/netxtreme2-<version>.<arch>.rpmwhere <arch> is the machine architecture such as i386:   rpm -ivh RPMS/i386/netxtreme2-<version>.i386.rpmNote that the --force option may be needed on some Linux distributionsif conflicts are reported.The drivers will be installed in the following path:2.4.x kernels:    /lib/modules/<kernel_version>/kernel/drivers/net/bnx2.o    /lib/modules/<kernel_version>/kernel/drivers/net/bnx2x.o2.6.0 kernels:    /lib/modules/<kernel_version>/kernel/drivers/net/bnx2.ko    /lib/modules/<kernel_version>/kernel/drivers/net/bnx2x.ko2.6.16 and newer kernels:    /lib/modules/<kernel_version>/kernel/drivers/net/bnx2.ko    /lib/modules/<kernel_version>/kernel/drivers/net/bnx2x.ko    /lib/modules/<kernel_version>/kernel/drivers/net/cnic.koNewer RHEL and SLES distros:    /lib/modules/<kernel_version>/updates/bnx2.ko    /lib/modules/<kernel_version>/updates/cnic.ko    /lib/modules/<kernel_version>/updates/bnx2x.ko    /lib/modules/<kernel_version>/updates/bnx2i.ko    /lib/modules/<kernel_version>/updates/bnx2fc.ko4. Unload existing driver if necessary:   rmmod bnx2   rmmod bnx2xIf the cnic driver is loaded, it should also be unloaded along with dependentdrivers:   rmmod bnx2fc   rmmod bnx2i   rmmod cnic5. Load the bnx2 driver for the BCM5706/BCM5708/5709/5716 devices:   insmod bnx2.oor   insmod bnx2.ko (on 2.6.x kernels)or   modprobe bnx2To load the bnx2x driver for the BCM57710/BCM57711/BCM57711E/BCM57712 devices:   insmod bnx2x.oor   insmod bnx2x.ko (on 2.6.x kernels)or   modprobe bnx2xTo load the cnic driver:   insmod cnic.koor   modprobe cnicTo load the bnx2i driver:   insmod bnx2i.koor   modprobe bnx2i   service iscsid restart (Please refer REDAME.bnx2i.txt for more details                           about iSCSI operation)To load the bnx2fc driver for BCM57712 device:   insmod bnx2fc.koor   modprobe bnx2fc   service fcoe start (Please refer README.bnx2fc.txt for more details about                        FCoE operation)   Note that the inbox kernel may have an older version of bnx2, bnx2x and cnicdriver.  It is important for FCoE offload user to unload these inbox versionsbefore attempting to load bnx2fc driver. There are 2 options to reach thedesired goal,   a) Reboot the server                OR   b) If already loaded, unload inbox bnx2, bnx2x, cnic drivers and load newly      installed version from netxtreme2-foce package using 'modprobe <DRV-NAME>'NOTE: Driver upgrade (rpm -Uvh) is not supported.NOTE: On SLES 11, change "allow_unsupported_modules" parameter value of      /etc/modprobe.d/unsupport-modules' from 0 to 1, until bnx2fc driver      is inbox. Failing to do so will not load bnx2fc.6. To configure network protocol and address, refer to various Linuxdocumentations. Building Driver From TAR File=============================The following are general guidelines for installing the driver.1. Create a directory and extract the files:   tar xvzf netxtreme2-<version>.tar.gz2. Build the drivers as a loadable module for the running kernel:   makeThe driver will be compiled for the running kernel by default. To buildthe driver for a kernel different than the running one, specify thekernel by defining it in KVER:  make KVER=<kernel version>where <kernel version> in the form of 2.x.y-z is the version of anotherkernel that is installed on the system.3. Test the driver by loading it (Same procedures as described in the    Source RPM section above).4. Install the driver and man page:   make installSee RPM instructions above for the location of the installed driver.5. To configure network protocol and address, refer to various Linuxdocumentations.Unloading and Removing Driver=============================If the driver was installed using rpm, do the following to remove it:rpm -e nextreme2Note - this will remove libfc2, libfcoe2, bnx2, bnx2x and cnic modules as wellIf the driver was installed using make install from the tar file, the drivershave to be manually deleted from the system. Refer to the section"Installing Source RPM Package" for the location of the installed driver.1. rmmod <driver>2. delete <driver>.ko from location given in section "Installing Source RPM Package"3. depmod -a **The kernel will now be back to original state prior to instalation from tar file.  You may now reload previous module versions if necessary.
