DPAA2 DPDK RTE FLOW

dehml — Mon, 27 Jul 2026 10:49:36 GMT

Hello,

I'm trying to create DPDK RTE FLOW on a DPAA2 SolidRun LX2160A Clearfog CX without success.
Is it normal that it doesn't work ?
What could be done to make it works ?

I'm quite newbie with NXP DPAA2 and NXP in general, so can you please explain your technical words.

Thanks.

testpmd> flow create 0 ingress pattern eth / ipv4 / end actions rss queues 0 1 end types ip ipv4 end / end DPAA2_NET: Add entry(0) to table(0) failed DPAA2_NET: Create flow failed (-22) port_flow_complain(): Caught PMD error type 1 (cause unspecified): cause: 0xfffff340a300, unknown: Operation not permitted

DPAA2 User Manual could be helpful

BTW. what kind of BSP or SDK is used? Any resource from official websit?

Check how the DPNI behind your DPDK port was created. From the Linux shell on the board:

restool dprc show dprc.1 --resources # find the dpni.X your DPDK port uses

restool dpni info dpni.X # look at the "options" line and "num_queues"

If options shows DPNI_OPT_NO_FS , or does not show DPNI_OPT_HAS_KEY_MASKING , that's your problem.

Recreate the DPNI with the right options. Either edit dynamic_dpl.sh (or the environment it reads — on NXP LSDK it is typically the DPNI_OPTIONS variable) so the create call looks like this :

restool dpni create \

--options=DPNI_OPT_HAS_KEY_MASKING \

--num-queues=2 \

--num-tcs=1 \

--container=dprc.2

Key points:

Do not include DPNI_OPT_NO_FS .

Do include DPNI_OPT_HAS_KEY_MASKING .

Set --num-queues to at least the number of queues your RSS action references (you asked for queues 0 and 1, so ≥ 2).

Then attach that DPNI to the DPDK container ( restool dprc assign … ) and rerun testpmd.

If you use a static DPL file , add the same to the dpni@X node :

dpni@1 {

options = "DPNI_OPT_HAS_KEY_MASKING";

num_queues = <2>;

...

};

and reflash the DPL via fsl_mc apply dpl … in U‑Boot.

Sanity‑check with a simpler rule first. Before RSS, confirm plain steering works:

testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.0.0.1 / end \

actions queue index 1 / end

If this passes but the RSS variant still fails, the remaining issue is queue count / distribution config, not the DPNI options.
