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

From: Leon Romanovsky <[email-masked]>
Date: Tue, 19 Jun 2018 08:47:23 +0300

From: Leon Romanovsky <[email-masked]>

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.
