[dpdk-dev] RSS: packet reaches to wrong queue

[Nishant Verma]

Hi All,

I am using DPDK 16.04 and pktgen 3.0.00

Issue is, Packet reaches to wrong queue at DPDK, if source IP of a packet
changed at pktgen-dpdk.

On my DPDK machine, i have configured RSS rule just for Destination IP
(172.10.10.2).

>From Pktgen when i changed *destination IP* as *172.10.10.2*, *proto *as
*ICMP*, and after that i tried command *ping4 0*
Packet reaches to correct queue in DPDK application.

But if i changed the source IP at packet gen (any IP other then
192.168.0.1), I am not getting packet at correct core on DPDK machine.



Here is my pktgen IP looks like.

If i revert my my source IP change, it again reached to correct core.



My port configuration is
