[dpdk-users] Enabling RSS with FM10K and testpmd

[Anthony Hart]

I think this question has been asked before, I’m trying to use RSS on a FM10K under testpmd.  Although testpmd creates the 2 queues on the port I’m still seeing all the traffic going to a single queue (the incoming traffic has a mix of DIP and SIP addresses).

Has anyone had any luck with this?

DPDK version 16.11

# testpmd -c 0x007e -n 4 -- -i --txq 2 --rxq 2 --nb-core 4 --numa --port-topology=chained

I’m using ‘redirect’ ACLs to forward traffic between ports in the FM10K

tp("create acl 0");
tp("create acl-rule 0 0");
tp("add acl-rule condition 0 0 src-port 0");
tp("add acl-rule action 0 0 redirect 1");
tp("add acl-rule action 0 0 count”);
