Linux Driver Checklist
NE0154601-00 A 6-3
To determine which driver to use:
1. See the Release Notes for more information about which Linux distributions
contain the inbox kernel GPL driver. The driver name is:
netxen_nic.ko
2. Type the following command to identify the netxen_nic.ko driver:
% lsmod | grep netxen_nic
Note that the netxen_nic.ko file is automatically blacklisted when the
Linux commercial GPL driver RPM is installed.
3. To disable the inbox kernel GPL driver (netxen_nic.ko):
a. Type the following command to remove the driver from the OS
memory:
% rmmod netxen_nic
b. Remove or rename the netxen_nic.ko file from the
/lib/modules/<uname -r>/kernel/drivers/net/netxen
directory.
The commercial GPL driver (nx_nic.ko) can be enabled after the inbox kernel
GPL driver module is disabled.
Check for MSI-X Support
MSI and MSI-X are supported by the QLogic adapter driver and firmware. Ensure
that the OS, kernel, and hardware support MSI-X.
Type the following command to see if MSI-X is supported:
% cat /proc/interrupts
NOTE:
The commercial GPL version of the driver (nx_nic.ko) contains the most
recent updates.
