130:0 0 PCI-MSI-X eth3:1

138:0 0 PCI-MSI-X eth3:2

146:0 0 PCI-MSI-X eth3:3

NOTE:

Some older Linux kernel versions may not support MSI-X.

Inbox Kernel GPL Driver and Blacklisting

NOTE:

There are two drivers for the QLogic adapter:

netxen_nic.ko. This is the in-kernel (inbox) GPL driver. It is released into the Linux upstream kernel and included in major Linux distributions.

nx_nic. This is the commercial GPL driver released by QLogic.

When the QLogic RPM binary package is installed, the inbox kernel GPL driver

(netxen_nic.ko) is blacklisted. Consequently, when the system is powered up, the netxen_nic.ko driver will not load. To prevent this from happening, you can

execute the RPM erase remove the QLogic RPM the prior setting, and the powered up.

command (rpm -enx_nic-[version]1), which will binary package so that the blacklisting will revert back to netxen_nic.ko driver will load when the system is

To check if the inbox kernel GPL driver has been installed on the system, check the /lib/modules/<kernel-version>/kernel/net/netxendirectory for the netxen_nic.ko driver. Remove or rename this file, and then reboot.

Alternately, uninstall the driver by typing the following command before continuing with the driver installation.

% rmmod netxen_nic

1[version] refers to the RPM package currently on the system. RPM packages can be located by typing the command: rpm -qa grep nx_.
