ixgbevf driver

Latest response

Hi,
I am trying to get the ixgbevf available on the interface.
Where to find the ixgbevf driver, and if really I need to compile? Do we not have a ready for use rpm package which does the job?

My kernel version:

2.6.32-431.11.2.el6.x86_64

Thanks in advance for help...

ixgbevf is included in the RHEL-6 kernel. If the module is not already loaded, try,

modprobe ixgbevf

Hi Akemi,
you are right... thanks a lot for that :D is there any possibility to list all the modules even if they are not loaded, with the distinction whate are loaded and what are not?

and second issue... how to change the driver on the interface... I still have this:

assword:

It will be best if you show the info on your network device.

lspci -nn | grep -i net

lspci -vv => provide the 'Ethernet controller' part of the output

Akemi,
thanks for next step...

I need to confess that I am trying to turn on the sriov enhanced networking on ec2 instance R3 with redhat6.5

I am trying to follow the procedure:

http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.html#enhanced-networking-linux

but there is no even a small piece how to deal with that on redhat.

moreover - the note about setting the .conf file with InterruptThrottleRate is not applicable, because
included ixgbefv module is not the one from sourceforge...
how to achieve the InterruptThrootleRate settings in the native RHEL included module? and keep it permanent?

I have many issues :/

Thanks in advance for your support...
