Kernel features like this have been superseded by rdma_netdev for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.
