Set dv_flow_en=2, but cannot create HWS action since HWS is not supported

Hi.
I’m trying to use rte_flow rules with asynchronous API in DPDK 22.11.
When I configure rte flow set using rte_flow_configure(), it returns like below and fail to configure.

mlx5_net: [mlx5dr_action_create_generic]: Cannot create HWS action since HWS is not supporte
d

I found that dv_flow_en is set as 2, but when querying HCA capability, mlx5dr_cmd_query_caps() returns caps->wqe_based_update of 0.

I guess there is something more that I should setup with firmware.
Is there anyone has tried asynchronous rte_flow APIs?
How can I use rte_flow_configure()?

Thanks

Are you familiar with the following links:
This is basis though might provide you some answers to your inquiries.
You might want to check that the HCA is supported and flashed with our latest FW respectively.

After installing latest FW, it worked. Thank you.

HI ,
I am also trying to create rte_flow rules with asynchronous API in DPDK 22.11.
rte_flow_configure() is failing with below error message:

Caught PMD error type 1 (cause unspecified): info get with incorrect steering mode: Operation not supported
ret :-95

1.looks i am missing some NIC settings. let me know what NIC settings to be done , before we try creating async flow rules?
2.how to set dv_flow_en to 2 ?
how to check value of dv_flow_en that is set? i saw in mlnx driver code that this parameter should be set to 2.
3.send me a sample code for creating asyn rte_flow rule.

Hi,

I have the same issue on a MCX653105A-ECAT NIC in ethernet mode. Could you please tell me whether HWS is supported on this SKU?

Thanks,
