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"
