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
