Merge tag 'rdma-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband

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.
