Hi,
I am trying to test the new rte_flow template and asynchronous APIs but when I start the testpmd application I got a segmentation fault.
$ sudo ./app/dpdk-testpmd -a 04:00.1,dv_flow_en=2 -- -i --rxq=8 --txq=8
EAL: Detected CPU lcores: 48
EAL: Detected NUMA nodes: 2
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'PA'
EAL: VFIO support initialized
EAL: Probe PCI driver: mlx5_pci (15b3:101d) device: 0000:04:00.1 (socket 0)
mlx5_common: DevX create q counter set failed errno=22 status=0 syndrome=0

testpmd: preferred mempool ops selected: ring_mp_mc
testpmd: create a new mbuf pool <mb_pool_1>: n=523456, size=2176, socket=1
testpmd: preferred mempool ops selected: ring_mp_mc
Warning! port-topology=paired and odd forward ports number, the last port will pair with itself.
Configuring Port 0 (socket 0)
Segmentation fault
Secondly, I also tried to debug the code and found that there are some missing functions in mlx5 PMD (mlx5_flow_hw_drv_ops):
Configuring Port 0 (socket 0)
