Inbox Kernel GPL Driver and Blacklisting
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,
(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]
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
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 /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.
Alternately, uninstall the driver by typing the following command before continuing

% rmmod netxen_nic
NOTE:
Some older Linux kernel versions may not support MSI-X.
NOTE:
There are two drivers for the QLogic adapter:
netxen_nic.ko. This is the in-kernel (inbox) GPL driver. It is released
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.
