Pull InfiniBand/RDMA changes from Roland Dreier: - Add ocrdma hardware driver for Emulex IB-over-Ethernet adapters - Add generic and mlx4 support for "raw" QPs: allow suitably privileged applications to send and receive arbitrary packets directly to/from the hardware - Add "doorbell drop" handling to the cxgb4 driver - A fairly large batch of qib hardware driver changes - A few fixes for lockdep-detected issues - A few other miscellaneous fixes and cleanups Fix up trivial conflict in drivers/net/ethernet/emulex/benet/be.h. * tag 'rdma-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband: (53 commits) RDMA/cxgb4: Include vmalloc.h for vmalloc and vfree IB/mlx4: Fix mlx4_ib_add() error flow IB/core: Fix IB_SA_COMP_MASK macro IB/iser: Fix error flow in iser ep connection establishment IB/mlx4: Increase the number of vectors (EQs) available for ULPs RDMA/cxgb4: Add query_qp support RDMA/cxgb4: Remove kfifo usage RDMA/cxgb4: Use vmalloc() for debugfs QP dump RDMA/cxgb4: DB Drop Recovery for RDMA and LLD queues RDMA/cxgb4: Disable interrupts in c4iw_ev_dispatch() RDMA/cxgb4: Add DB Overflow Avoidance RDMA/cxgb4: Add debugfs RDMA memory stats cxgb4: DB Drop Recovery for RDMA and LLD queues cxgb4: Common platform specific changes for DB Drop Recovery cxgb4: Detect DB FULL events and notify RDMA ULD RDMA/cxgb4: Drop peer_abort when no endpoint found RDMA/cxgb4: Always wake up waiters in c4iw_peer_abort_intr() mlx4_core: Change bitmap allocator to work in round-robin fashion RDMA/nes: Don't call event handler if pointer is NULL RDMA/nes: Fix for the ORD value of the connecting peer ...
