I couldn't manage to configure RSS

I couldn't manage to configure RSS

Hi,

I successfully managed to run l2fw example and also l3fw with only one
queue. But I couldn't config the RSS in l3fw and also test-pmd application.
I simply create two queues per port on two lcores and set the RSS_ETH_IPV4
(I laso tried other options). I generate a traffic with different
destination addresses but all the traffic goes to the first queue and the
other queue in both applications is empty !
I also fully read both application codes, api_reference, programmers guide,
but unfortunately couldn't find anyway to activate this feature. Have you
any advice for me? Is there any trick or other configuration I should
enable?
My Ethernet card is X540, and I'm using Intel E5-2650 CPU on ubuntu LTS
12.0.4.

Regards
-Hamed

Don't you have to different source addresses? How come packets with
different destination addresses go to your machine?

With test-pmd, you need to make sure you allow enough cores to handle each RSS queue.  And as the previous poster mentioned, you must generate traffic to a wide range of destination addresses.
