    How to change the IPoIB mode of Infiniband Interface usring Mellanox ConnectX-4.


      Changing the mode of an InfiniBand interface by echoing either connected or datagram to /sys/class/net/ibN/mode is not supported. 

      Modifying the /etc/infiniband/openibd.conf configuration file also does not work.
