The device name printed via ctx_print_test_info is not the same as the actual used device name when rdma_cm is enabled

I modified the code to print the device name through the parameters inside the struct ibv_context.I found the device name printed by ctx_print_test_info is not the same as the parameters inside the struct ibv_context, further I found ctx_print_test_info just print the user parameter... Why is this?
My code is like this:

The execution result is as follows
server:

client:

Looking forward to reply from you when it is convenient, any reply will be helpful for me, thanks!!

Hi,

I didn't manage to repro it , are you sure that you are not passing mlx5_0 ip to perftest ?
can you please provide more information about your setup ?

Thanks

Thanks for your kind reply.
Sry, I passed the mlx5_0 ip of server to perftest in client side. It's my bad, so the output printed by server is expected.
But the main problem is that I try to use mlx5_1 to connect server in client side, but perftest just print device name passed by user(mlx5_1), instead the real used(mlx5_0). I used -R which means use rdma_cm, and I learned that rdma_cm seems like cannot choose device in client side, is that true?

Thanks
