Meir Lichtinger says:

====================
ConnectX-7 supports setting relaxed ordering read/write mkey attribute by
UMR, indicated by new HCA capabilities, so extend mlx5_ib driver to
configure UMR control segment
====================

Based on the mlx5-next branch at
      git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux
due to dependencies.

  RDMA/mlx5: Set mkey relaxed ordering by UMR with ConnectX-7
  RDMA/mlx5: Use MLX5_SET macro instead of local structure
  RDMA/mlx5: ConnectX-7 new capabilities to set relaxed ordering by UMR
