            # Protocol modules
            # Common modules
            rdma_ucm
            ib_umad
            ib_uverbs

            address 192.168.38.71
            netmask 255.255.255.0
            broadcast 192.168.38.255
            

Then, start the interface

ifup ib0

Test the interface using the following commands

ibstat ibhosts
