Network Installations
For network installations through NFS, FTP, or HTTP (using a network boot disk
or PXE), you may need a driver disk that contains the bnx2x driver. The driver disk
includes images for the most recent Red Hat and SUSE versions. Boot drivers for
other Linux versions can be compiled by modifying the makefile and the make
environment. Additional information is available from the Red Hat Web site:
Setting Values for Optional Properties
Optional properties exist for these drivers:
bnx2x Driver Parameters
Parameters for the bnx2x driver include the following:
int_mode
Use the optional parameter
int_mode
to force using an interrupt mode other
than MSI-X. By default, the driver tries to enable MSI-X if it is supported by the
kernel. If MSI-X is not attainable, the driver tries to enable MSI if it is supported by
the kernel. If MSI is not attainable, the driver uses the legacy INTx mode.
To force using the legacy INTx mode on all 8400/3400 Series network adapters in
the system, set the
int_mode
parameter to
1
as shown in the following:
insmod bnx2x.ko int_mode=1
or
modprobe bnx2x int_mode=1
Set the
int_mode
parameter to
2
to force using MSI mode on all 8400/3400
Series Adapters in the system as follows:
insmod bnx2x.ko int_mode=2
or
modprobe bnx2x int_mode=2
Set the
int_mode
parameter to
3
to force using MSI-X mode on all 8400/3400
Series Adapters in the system.
