Subject: [PATCH for-next 04/14] net/mlx5: Add KSM support
Date: Tue, 25 Oct 2016 18:00:07 +0300	[thread overview]
Message-ID: <1477407617-20745-5-git-send-email-saeedm@mellanox.com> (raw)
In-Reply-To: <1477407617-20745-1-git-send-email-saeedm@mellanox.com>

From: Artemy Kovalyov <artemyko@mellanox.com>

Add to struct mlx5_ifc_cmd_hca_cap_bits capability bits
indicating related value/field is supported:
* fixed_buffer_size - MLX5_MKC_ACCESS_MODE_KSM
* umr_extended_translation_offset -translation_offset_42_16
    in UMR ctrl segment
* null_mkey - null_mkey in QUERY_SPECIAL_CONTEXTS

Add MLX5_MKC_ACCESS_MODE_KSM enum value

Add null_mkey field to struct mlx5_ifc_query_special_contexts_out_bits
