Hi,
I am using RSS functionality on 82599 with dpdk igb_uio driver.
I am able to get proper hash for untagged and single tagged packets. But for double tagged packets, it is not working. I get hash value 0 for all packets.
Is there any additional flag I need to enable for this?
Regards,
Surya

I have also tried by enabling vlan_extended support in port_conf and set rss_hf as all 1s.
.hw_vlan_extend = 1
.rss_hf = ~0
Still there is no change…

I don't think the hardware supports using RSS on packets with a double VLAN tag.
