Yes, I checked with single-tagged and double-tagged.

Thank you. It looks that with this patch (part of v20.11 release?) it is now able to do RSS hash on IP|TCP|UDP fields even in the presence of multiple VLAN tags

I've tried applying the patch to the 20.08 release I have downloaded, but the install fails on
  ../drivers/net/mlx5/mlx5_flow.c:1363:4: error: ‘const struct rte_flow_item_eth’ has no member named ‘has_vlan’
 .has_vlan = ext_vlan_sup ? 1 : 0,

I assume there are other prior contributions that contain the API changes, is there a way I can download and apply them all?

Hi all,



I think we had the issue with Mellanox NICs. I applied this patch and it got resolved.
