[PATCH mlx5-next 2/3] net/mlx5: Add hardware definitions for dump_fill_mkey

From: Leon Romanovsky <leon@kernel.org>
Date: 2018-06-19 05:47:41
Also in: linux-rdma
Subsystem: mellanox mlx5 ib driver, mellanox mlx5 core vpi driver, the rest · Maintainers: Leon Romanovsky, Saeed Mahameed, Tariq Toukan, Mark Bloch, Linus Torvalds

From: Leon Romanovsky <redacted>

MLX5 IB HCA offers the memory key, dump_fill_mkey to boost
performance by forcing local HCA operations to skip the PCI bus
access,

This patch adds needed hardware definitions.
