Install Using KMP RPM
NOTE: KMP is only supported on SLES11.
The KMP RPMs update existing igbvf RPMs currently installed on the system. These updates are provided by SuSE in
the SLES release. If an RPM does not currently exist on the system, the KMP will not install.
The RPMs are provided for supported Linux distributions. The naming convention for the included RPMs is:
intel-<component name>-<component version>.<arch type>.rpm
For example, intel-igbvf-1.3.8.6-1.x86_64.rpm: igbvf is the component name; 1.3.8.6-1 is the component version; and
x86_64 is the architecture type.
KMP RPMs are provided for supported Linux distributions. The naming convention for the included KMP RPMs is:
intel-<component name>-kmp-<kernel type>-<component version>_<kernel version>.<arch type>.rpm
For example, intel-igbvf-kmp-default-1.3.8.6_2.6.27.19_5-1.x86_64.rpm: igbvf is the component name; default is the
kernel type; 1.3.8.6 is the component version; 2.6.27.19_5-1 is the kernel version; and x86_64 is the architecture type.
To install the KMP RPM, type the following two commands:
rpm -i <rpm filename>
rpm -i <kmp rpm filename>
For example, to install the igbvf KMP RPM package, type the following:
rpm -i intel-igbvf-1.3.8.6-1.x86_64.rpm
rpm -i intel-igbvf-kmp-default-1.3.8.6_2.6.27.19_5-1.x86_64.rpm
Command Line Parameters
If the driver is built as a module, the following optional parameters are used by entering them on the command line with
the modprobe command using this syntax:
modprobe igbvf [<option>=<VAL1>,<VAL2>,...]
A value (<VAL#>) must be assigned to each network port in the system supported by this driver. The values are applied
to each instance, in function order. For example:
modprobe igbvf InterruptThrottleRate=16000,16000
In this case, there are two network ports supported by igb in the system. The default value for each parameter is gen-
erally the recommended setting, unless otherwise noted.
The following table contains parameters and possible values for modprobe commands:
Parameter Valid Range/Settings
Name
Interrupt- 0, 1, 3, 100-100000
ThrottleRate (0=off, 1=dynamic, 3=d-
dynamic conservative)
Default Description
3 The driver can limit the number of interrupts per second
that the adapter will generate for incoming packets. It
does this by writing a value to the adapter that is based
on the maximum number of interrupts that the adapter
will generate per second.
Setting InterruptThrottleRate to a value greater or equal
to 100 will program the adapter to send out a maximum
of that many interrupts per second, even if more packets
have come in. This reduces interrupt load on the system
and can lower CPU utilization under heavy load, but will
increase latency as packets are not processed as
quickly.
The default behavior of the driver previously assumed a
static InterruptThrottleRate value of 8000, providing a
