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.
