Merge tag 'rdma-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband
Pull infiniband changes from Roland Dreier: "Second batch of changes for the 3.7 merge window: - Late-breaking fix for IPoIB on mlx4 SR-IOV VFs. - Fix for IPoIB build breakage with CONFIG_INFINIBAND_IPOIB_CM=n (new netlink config changes are to blame). - Make sure retry count values are in range in RDMA CM. - A few nes hardware driver fixes and cleanups. - Have iSER initiator use >1 interrupt vectors if available." * tag 'rdma-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband: RDMA/cma: Check that retry count values are in range IB/iser: Add more RX CQs to scale out processing of SCSI responses RDMA/nes: Bump the version number of nes driver RDMA/nes: Remove unused module parameter "send_first" RDMA/nes: Remove unnecessary if-else statement RDMA/nes: Add missing break to switch. mlx4_core: Adjust flow steering attach wrapper so that IB works on SR-IOV VFs IPoIB: Fix build with CONFIG_INFINIBAND_IPOIB_CM=n
