Note
Some combinations of property values may conflict and result in
failures. The driver cannot detect all conflicting combinations.
This property is used to disable Message Signal Interrupts (MSI). The
property is valid only on 2.6 kernels that support MSI. This property cannot
be used on 2.4 kernels. 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. To set the bnx2x driver, enter one of the
following:
insmod bnx2x.ko disable_msi=1
or
modprobe bnx2x disable_msi=1
