Inbox Kernel GPL Driver and Blacklisting

The output of this command is similar to the following:

[root@apps4242 ~]# cat /proc/interrupts
CPU0 CPU1
58: 164 7 PCI-MSI-X eth2
66: 0 0 PCI-MSI-X eth2:1
74: 6 0 PCI-MSI-X eth2:2
82: 0 0 PCI-MSI-X eth2:3
122: 3195 0 PCI-MSI-X eth3
130: 0 0 PCI-MSI-X eth3:1
138: 0 0 PCI-MSI-X eth3:2
146: 0 0 PCI-MSI-X eth3:3

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 command (rpm -e nx_nic-[version]

1

), which will 

remove the QLogic RPM binary package so that the blacklisting will revert back to 
the prior setting, and the netxen_nic.ko driver will load when the system is 

powered up. 

To check if the inbox kernel GPL driver has been installed on the system, check 
the /lib/modules/<kernel-version>/kernel/net/netxen directory 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 

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

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.

1

[version] refers to the RPM package currently on the system. RPM packages can be located by

typing the command: rpm -qa | grep nx_.
