IPoIB
The IP over IB (IPoIB) driver is a network interface implementation over InfiniBand. IPoIB
encapsulates IP datagrams over an InfiniBand connected or datagram transport service. IPoIB pre-
appends the IP datagrams with an encapsulation header, and sends the outcome over the Infini-
Band transport service. The interface supports unicast, multicast and broadcast. For details, see
Chapter 4.2, “IP over InfiniBand”.
1.5 Supported Hardware Compatibility

that Reliable Connected (RC) mode is not supported.
