In the case of IPoIB, and maybe in other cases, the network device is managed by an upper-layer protocol (ULP). In order to expose this network device to other users of the IB device, let ULPs implement a callback that returns network device according to connection parameters. The IB device and port, together with the P_Key and the GID should be enough to uniquely identify the ULP net device. However, in current kernels there can be multiple IPoIB interfaces created with the same GID. Furthermore, such configuration may be desireable to support ipvlan-like configurations for RDMA CM with IPoIB. To resolve the device in these cases the code will also take the IP address as an additional input.
