Subject: [dpdk-stable] [PATCH v2 11/20] net/mlx5: remove kernel version check
Date: Wed,  9 May 2018 18:04:03 +0300	[thread overview]
Message-ID: <34d14f356f91582c1394a3c93805c6eea1e78777.1525878119.git.shahafs@mellanox.com> (raw)
In-Reply-To: <cover.1525878118.git.shahafs@mellanox.com>

From: Nélio Laranjeiro <nelio.laranjeiro@6wind.com>

[ upstream commit f47ba80080ab81ad513f843407bec7178fed8857 ]

Kernel version check was introduced in
commit 3a49ffe38a95 ("net/mlx5: fix link status query")
due to a bug fixed by
