Loading iWARP Driver

The driver must be loaded by the root user. Any attempt to load the driver as a regular user will
fail.
To load the iWARP driver we need to load the NIC driver and core RDMA drivers first. Run the
following commands:
[root@host~]# modprobe cxgb4
[root@host~]# modprobe iw_cxgb4
[root@host~]# modprobe rdma_ucm
Optionally, you can start the iWARP Port Mapper daemon to enable port mapping:
[root@host~]# iwpmd
