RDMA/cma: Add multicast communication support

2007-02-16T22:29:07Z

Extend rdma_cm to support multicast communication. Multicast support is added to the existing RDMA_PS_UDP port space, as well as a new RDMA_PS_IPOIB port space. The latter port space allows joining the multicast groups used by IPoIB, which enables offloading IPoIB traffic to a separate QP. The port space determines the signature used in the MGID when joining the group. The newly added RDMA_PS_IPOIB also allows for unicast operations, similar to RDMA_PS_UDP. Supporting the RDMA_PS_IPOIB requires changing how UD QPs are initialized, since we can no longer assume that the qkey is constant. This requires saving the Q_Key to use when attaching to a device, so that it is available when creating the QP. The Q_Key information is exported to the user through the existing rdma_init_qp_attr() interface. Multicast support is also exported to userspace through the rdma_ucm. Signed-off-by: Roland Dreier

IB: IP address based RDMA connection manager

2006-06-18T03:37:29Z

Kernel connection management agent over InfiniBand that connects based on IP addresses. The agent defines a generic RDMA connection abstraction to support clients wanting to connect over different RDMA devices. The agent also handles RDMA device hotplug events on behalf of clients.
