Hello Wenxu,



Can you please create a new BZ ticket?

Looks like this is not handled properly in our pmd and we’ll handle it and update.

What DPDK version are you using?

Can you try using upstream? We had a fix for a similar issue recently.

Hi mlnx teams,


I test the upstream dpdk with the nvgre inner rss action with dpdk-testpmd


# ./dpdk-testpmd -c 0x1f  -n 4 -m 4096 -w "0000:19:00.1"  --huge-dir=/mnt/ovsdpdk  -- --forward-mode=rxonly --rxq=4 --txq=4 --auto-start --nb-cores=4

#  testpmd>> flow create 0 ingress pattern eth / ipv4 / nvgre / end actions rss level 2 types ip udp tcp end queues 0 1 2 3 end / end


Add rte flow for nvgre wit action inner（level 2） rss to the queues 0,1,2,3.


And I test this with the same underlay tunnel but differrent inner ip address/udp ports. But Only one queue recieve the packet.




And if I test this with vxlan case. it works as we expect.
testpmd>> flow create 0 ingress pattern eth / ipv4 / udp / vxlan / end actions rss level 2 types ip udp tcp end queues 0 1 2 3 end / end




# lspci | grep Ether
19:00.0 Ethernet controller: Mellanox Technologies MT27800 Family [ConnectX-5]
19:00.1 Ethernet controller: Mellanox Technologies MT27800 Family [ConnectX-5]



Fw version is 16.29.1016
# ethtool -i net3
driver: mlx5_core
version: 5.12.0-rc4+
firmware-version: 16.29.1016 (MT_0000000080)


Are there any problems for my test case.
