Thank you for your quick response.
Firmware version is 22.30.1004, and OFED version is OFED-5.8-1.1.2.
Sincerely,

What’s the FW version are you using?
If you are using OFED driver, it is suggested that you try the OFED >=5.8 with the FW inside.

Thank you Zhao.
I tried it, but now mlx5 driver returned error.
mlx5_net: [mlx5dr_action_create_generic]: Cannot create HWS action since HWS is not supported
It is what I saw in my original code before trying on testpmd.
It seems to be an issue from connectX-6 configuration.
Is there anyone ever tried to use asynchronous API with connectX-6?
Setting dv_flow_en=2 and dv_esw_en=1 seems not enough.
I explored the mlx5 code, and found that rte_flow_configure() queries HCA capability by mlx5dr_cmd_query_caps().
In my case, rte_flow_configure() returned error since caps->wqe_based_update is set by 0.
Is there anyone know how to set this value to non-zero?
I already wrote the same question on nvidia forum.
Sincerely,
Junghan Yoon

Hi Junghan,
In testpmd, you can easily do it by:
port stop all
# or port stop 0
flow configure 0 ……
# if there are other port(s)
# flow configure Y ……
port start all
# or port start 0
With the source code implementation, you can configure it before starting a device.

Subject: About rte_flow asynchronous API
Hi.
I’m trying to use testpmd to test rte_flow with asynchronous API in DPDK 22.11.
I turned on dv_esw_en=1 by echoing switchdev to /sys/class/net/…., and set dv_flow_en to 2 to use connectX-6 HWS (hardware steering).
sudo build/app/dpdk-testpmd -a 0000:8a:00.0,dv_flow_en=2 -a 0000:8a:00.1,dv_flow_en=2 -- -i --rxq=1 --txq=1
In the prompt, I typed below
flow configure 0 queues_number 1 queues_size 10 counters_number 0 aging_counters_number 0 meters_number 0 flags 0
but it said “Device with port_id=0 already started.”.
I know rte_flow_configure() call should be in the middle of rte_eth_dev_configure() and rte_eth_dev_start().
So, I run testpmd by below to postpone device start,
sudo build/app/dpdk-testpmd -a 0000:8a:00.0,dv_flow_en=2 -a 0000:8a:00.1,dv_flow_en=2 -- -i --rxq=1 --txq=1 --disable-device-start
However, now not only rte_eth_dev_start() but also rte_eth_dev_configure() does not start, so it said “Device with port_id=0 is not configured.”.
How can I run rte_flow_configure() between rte_eth_dev_configure() and rte_eth_dev_start() in testpmd?
Is there any parameter to postpone only rte_eth_dev_start()?
Sincerely,
Junghan Yoon.
