Subject: [dpdk-users] VLAN tagged traffic IP distribution with MLNX-5.2
Date: Tue, 6 Apr 2021 09:47:06 +0000 [thread overview]
Message-ID: <OSBPR01MB41521A86D4B483F0E5329163E4769@OSBPR01MB4152.jpnprd01.prod.outlook.com> (raw)
Hello all,
I am having problem with IP RSS distribution when using Mellanox card (HPE 100G card: Mellanox Technologies MT27800 Family [ConnectX-5]) and different version of Mellanox EN/OFED package when receiving VLAN traffic.
It seems that when DPDK is compiled with Mellanox 5.2 (mlnx-en-5.2-1.0.4.0-rhel7.9-x86_64.tgz) then VLAN tagged traffic is not RSS distributed to different queues when using IP distribution.
When using older Mellanox 4.6 (mlnx-en-4.7-3.2.9.0-rhel7.7-x86_64.tgz) the RSS is working correctly.
We are using dpdk 19.11.4 but the result is same with dpdk 19.11.7.
See my test with testpmd compiled with different version of Mellanox package using 4 queues and RSS IP distribution:
In case of Mellanox 4.x VLAN traffic is distributed into 4 queues. When using Mellanox 5.2 all VLAN traffic is delivered to queue 0.
When using non VLAN traffic everything is working correctly / distributed.
Is there anything I am missing for VLAN or is it a bug?
b.r.
Pavel
