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£º
  1 E810 NIC card attached to IXIA test generator. 
   Each port has 2 rx queues assigned, dpdk_testpmd runs for test


[result]£º
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.
