About rte_flow asynchronous API

[Junghan Yoon]

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.
