Merge branch 'devx_set_get' into rdma.git for-next
Leon Romanovsky says: ==================== Be more strict with DEVX get/set operations for the obj_id. ==================== Based on the mlx5-next branch at git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux due to dependencies. * branch 'devx_set_get': RDMA/mlx5: Use strict get/set operations for obj_id RDMA/mlx5: Use the correct obj_id upon DEVX TIR creation net/mlx5: Expose ifc bits for query modify header
