Chapter 4: Installing the Linux Drivers

Network Installations

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 bnx2

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

Next, back up the old files and the 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

For network installations through NFS, FTP, or HTTP (using a network boot disk or PXE), a driver disk that contains the bnx2 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, http://www.redhat.com.

Setting Values for Optional Properties

You can set values for optional properties for the bnx2 and bnx2i Linux drivers. See the following:

ˆ“Setting Optional Properties for the bnx2 Driver” on page 58

ˆ“Setting Optional Properties for the bnx2i Driver” on page 59

Setting Optional Properties for the bnx2 Driver

The disable_msi optional property can be supplied 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. The ethtool commands can be put in a startup script such as /etc/rc.local to preserve the settings across a reboot.
