I'm doing some tests on E810(8086:1591) NIC using dpdk-20.11.5.

ddp: 1.3.35.0, ICE COMMS Package

test-configuration：

1 E810 NIC card attached to IXIA test generator.

Each port has 2 rx queues assigned, dpdk_testpmd runs for test

[result]：

1. when IXIA send packets with no-vlan or 1-vlan, the RSS works fine，“show fwd stats all” indicates that all rx queues receive packets；

2. but when send packets with double-vlan，the RSS didn't work，only queue-0 receives packets. I've tried "vlan extend on/off" OR "port config all rss on",etc，nothing changed.

[question]

How can I get RSS working when QinQ packets received？

many thanks if anyone can give me some hint.
