RDMA/ucma: Add option to manually set IB path Export rdma_set_ib_paths to user space to allow applications to manually set the IB path used for connections. This allows alternative ways for a user space application or library to obtain path record information, including retrieving path information from cached data, avoiding direct interaction with the IB SA. The IB SA is a single, centralized entity that can limit scaling on large clusters running MPI applications. Future changes to the rdma cm can expand on this framework to support the full range of features allowed by the IB CM, such as separate forward and reverse paths and APM.
