Subject: [PATCH net 02/12] net/mlx5: Check FW limitations on log_max_qp before setting it
Date: Wed, 28 Dec 2016 14:58:32 +0200	[thread overview]
Message-ID: <1482929922-32626-3-git-send-email-saeedm@mellanox.com> (raw)
In-Reply-To: <1482929922-32626-1-git-send-email-saeedm@mellanox.com>

From: Noa Osherovich <noaos@mellanox.com>

When setting HCA capabilities, set log_max_qp to be the minimum
between the selected profile's value and the HCA limitation.

Fixes: 938fe83c8dcb ('net/mlx5_core: New device capabilities...')
