Patching PCI

Files (Optional)

This is an optional procedure that describes how to patch PCI files for

identification by other vendors.

For hardware detection utilities, such as Red Hat kudzu, to properly

identify bnx2x supported devices, you may need to update a number of

files containing PCI vendor and device information.

Apply the updates by running the scripts provided in the supplemental tar

file. For example, on Red Hat Enterprise Linux, apply the updates by

entering the following commands:

./patch_pcitbl.sh /usr/share/hwdata/pcitable

pci.updates

/usr/share/hwdata/pcitable.new bnx2x

./patch_pciids.sh /usr/share/hwdata/pci.ids

pci.updates

/usr/share/hwdata/pci.ids.new

Next, back up the old files and rename the new files by entering the

following copy commands:

cp /usr/share/hwdata/pci.ids /usr/share/hwdata/

old.pci.ids

cp /usr/share/hwdata/pci.ids.new /usr/share/hwdata/

pci.ids

cp /usr/share/hwdata/pcitable /usr/share/hwdata/

old.pcitable

cp /usr/share/hwdata/pcitable.new /usr/share/hwdata/

pcitable

Network

Installations

For network installations through NFS, FTP, or HTTP (using a network

boot disk or PXE), a driver disk that contains the bnx2x driver may be

needed. The driver disk images for the most recent Red Hat and SuSE

versions are included. Boot drivers for other Linux versions can be

compiled by modifying the Makefile and the make environment. Further

information is available from the Red Hat website at www.redhat.com.

Setting Optional

Properties for the

bnx2x Driver

The disable_msi optional property can be used as a command line

argument to the insmod or modprobe command. The property can also be

set in the modprobe.conf command. See the man page for more

information.

All other driver settings can be queried and changed using the ethtool

utility. See the ethtool man page for more information. The ethtool

settings do not persist across a reboot or module reload. In addition, you

can put the ethtool commands in a startup script, such as /etc/rc.local, to
