Hello,

I am configuring RSS through through rte_eth_dev_configure using
rte_eth_conf with mq_ mode = ETH_MQ_RSS and specifying rss_hf = ETH_RSS_IP
| ETH_RSS_TCP | ETH_RSS_UDP. I've noticed that even single VLAN tagged
packets do not get hashed.

Is there a flag I am missing to do this? Is RSS possible on tagged packets?

I am using a connectx-5 with the mlx5 PMD

Thanks,

Hello Gerry,

Thanks for your email.

What version of DPDK are you using?

We are familiar with this issue in our mlx5 pmd in the latest code and are working on a fix.

Will let you know as soon as we have it.

Thanks,
Asaf Penso

Regards,
Asaf Penso

Hi all,

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

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?

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

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.
