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.
