Supported iWARP Applications
Linux-supported RDMA applications for iWARP include the following:
 ibv_devinfo, ib_devices
 ib_send_bw/lat, ib_write_bw/lat, ib_read_bw/lat, ib_atomic_bw/lat
For iWARP, all applications must use the RDMA communication manager
(rdma_cm) using the
-R option.
 rdma_server, rdma_client
 rdma_xserver, rdma_xclient
 rping
 NFS over RDMA (NFSoRDMA)
 iSER (for details, see Chapter 9 iSER Configuration)
 NVMe-oF (for details, see Chapter 13 NVMe-oF Configuration with RDMA)
