Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull base rdma updates from Doug Ledford: "Round one of 4.8 code: while this is mostly normal, there is a new driver in here (the driver was hosted outside the kernel for several years and is actually a fairly mature and well coded driver). It amounts to 13,000 of the 16,000 lines of added code in here. Summary: - Updates/fixes for iw_cxgb4 driver - Updates/fixes for mlx5 driver - Add flow steering and RSS API - Add hardware stats to mlx4 and mlx5 drivers - Add firmware version API for RDMA driver use - Add the rxe driver (this is a software RoCE driver that makes any Ethernet device a RoCE device) - Fixes for i40iw driver - Support for send only multicast joins in the cma layer - Other minor fixes" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (72 commits) Soft RoCE driver IB/core: Support for CMA multicast join flags IB/sa: Add cached attribute containing SM information to SA port IB/uverbs: Fix race between uverbs_close and remove_one IB/mthca: Clean up error unwind flow in mthca_reset() IB/mthca: NULL arg to pci_dev_put is OK IB/hfi1: NULL arg to sc_return_credits is OK IB/mlx4: Add diagnostic hardware counters net/mlx4: Query performance and diagnostics counters net/mlx4: Add diagnostic counters capability bit Use smaller 512 byte messages for portmapper messages IB/ipoib: Report SG feature regardless of HW UD CSUM capability IB/mlx4: Don't use GFP_ATOMIC for CQ resize struct IB/hfi1: Disable by default IB/rdmavt: Disable by default IB/mlx5: Fix port counter ID association to QP offset IB/mlx5: Fix iteration overrun in GSI qps i40iw: Add NULL check for puda buffer i40iw: Change dup_ack_thresh to u8 i40iw: Remove unnecessary check for moving CQ head ...
