This has been a smaller cycle with many of the commits being smallish code
 fixes and improvements across the drivers.
 
 - Driver updates for bnxt_re, cxgb4, hfi1, hns, mlx5, nes, qedr, and rxe
 
 - Memory window support in hns
 
 - mlx5 user API 'flow mutate/steering' allows accessing the full packet
   mangling and matching machinery from user space
 
 - Support inter-working with verbs API calls in the 'devx' mlx5 user API, and
   provide options to use devx with less privilege
 
 - Modernize the use of syfs and the device interface to use attribute groups
   and cdev properly for uverbs, and clean up some of the core code's device list
   management
 
 - More progress on net namespaces for RDMA devices
 
 - Consolidate driver BAR mmapping support into core code helpers and rework
   how RDMA holds poitners to mm_struct for get_user_pages cases
 
 - First pass to use 'dev_name' instead of ib_device->name
 
 - Device renaming for RDMA devices
