"User space software steering" is a way to add rules to the packet processing. The rules can be written by user space applications and they are executed by the HW. The rdma-core (RDMA userspace counterpart) is exposing the proper API for that functionality. https://github.com/linux-rdma/rdma-core/blob/master/providers/mlx5/man/mlx5dv_dr_flow.3.md Thanks
