  "message": "RDMA/cma: Add multicast communication support\n\nExtend rdma_cm to support multicast communication.  Multicast support\nis added to the existing RDMA_PS_UDP port space, as well as a new\nRDMA_PS_IPOIB port space.  The latter port space allows joining the\nmulticast groups used by IPoIB, which enables offloading IPoIB traffic\nto a separate QP.  The port space determines the signature used in the\nMGID when joining the group.  The newly added RDMA_PS_IPOIB also\nallows for unicast operations, similar to RDMA_PS_UDP.\n\nSupporting the RDMA_PS_IPOIB requires changing how UD QPs are initialized,\nsince we can no longer assume that the qkey is constant.  This requires\nsaving the Q_Key to use when attaching to a device, so that it is\navailable when creating the QP.  The Q_Key information is exported to\nthe user through the existing rdma_init_qp_attr() interface.\n\nMulticast support is also exported to userspace through the rdma_ucm.\n\nSigned-off-by: Roland Dreier \u003crolandd@cisco.com\u003e\n",
