Subject: [PATCH net-next V1 01/13] net/mlx5: Refactor mlx5_core_mr to mkey
From: Matan Barak <matanb@...lanox.com>
Mlx5's mkey mechanism is also used for memory windows.
The current code base uses MR (memory region) naming, which is
inaccurate. Changing MR to mkey in order to represent its different
usages more accurately.
