Kernel features like this have been superseded by rdma_netdev for ipoib - eg mlx5 implements all offloads through this API. RSS was merged to userspace with a different API, see ibv_create_rwq_ind_table.3 ibv_create_wq.3 ibv_modify_wq.3 And TSS was merged to userspace with a different API, see IBV_QP_CREATE_SOURCE_QPN.
