persist across a reboot or module reload. The ethtool commands can be put in a startup script such as /etc/rc.local to
preserve the settings across a reboot.
NOTE: Some combinations of property values may conflict and result in failures. The driver cannot detect all such
conflicting combinations.
This property is used to disable Message Signal Interrupts (MSI), and the property is valid only on 2.6 kernels that support
MSI. On 2.4 kernels, this property cannot be used. By default, the driver enables MSI if it is supported by the kernel. It runs
an interrupt test during initialization to determine if MSI is working. If the test passes, the driver enables MSI. Otherwise, it
uses legacy INTx mode.
insmod bnx2.ko disable_msi=1
or
modprobe bnx2 disable_msi=1
BNX2X DRIVER
disable_tpa
The disable_tpa parameter can be supplied as a command line argument to disable the Transparent Packet Aggregation
(TPA) feature. By default, the driver will aggregate TCP packets. Use disable_tpa to disable the advanced TPA feature.
Set the disable_tpa parameter to 1 as shown below to disable the TPA feature on all NetXtreme II network adapters in the
system. The parameter can also be set in modprobe.conf. See the man page for more information.
insmod bnx2x.ko disable_tpa=1
or
modprobe bnx2x disable_tpa=1
int_mode
The int_mode parameter is used to force using an interrupt mode.
Set the int_mode parameter to 1 to force using the legacy INTx mode on all NetXtreme II adapters in the system.
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 NetXtreme II adapters in the system.
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 NetXtreme II adapters in the system.
