Hi, I am new to both bluefield platform and DOCA development. When I try to run the doca flow sample code with the following command:
./build/doca_flow_switch_direction_info -- -p 03:00.0 -r sf[2,3] -l 60
I got the error as follows:
root@localhost:/opt/mellanox/doca/samples/doca_flow/flow_switch_direction_info# ./build/doca_flow_switch_direction_info -- -p 03:00.0 -r sf[2,3] -l 60

From the above error message, the main problem is that in the DPDK init process, the function call rte_eth_dev_count_avail returns 1, which is expected as 3. Can anyone help me figure out why this problems exist? I have no idea.
I am using DOCA version 2.9.1 and reading the documentation of DOCA 2.9.1.
