From: Artemy Kovalyov <artem...@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
