# Configure Soft-RoCE (RXE): Create RXE device over network interface (e.g. eth0): # rdma link add rxe_eth0 type rxe netdev eth0 Use the status command to display the current configuration: # rdma link If you are using a Mellanox HCA, make sure that the mlx4_ib/mlx5_ib kernel module is not loaded (modprobe –rv mlx4_ib) in the soft-RoCE machine. Now you have an Infiniband device called “rxe0_eth0” that can be used to run any RoCE app.
