Port Type Management

ConnectX®-3 onwards adapter cards’ ports can be individually configured to work as InfiniBand or Ethernet ports. By default, ConnectX® family adapter cards VPI ports are initialized as InfiniBand ports. If you wish to change the port type use the mstconfig after the driver is loaded.
