Subject: [dpdk-stable] [PATCH 13/14] net/mlx5: fix link speed capability information
Date: Tue, 8 Nov 2016 11:36:54 +0100 [thread overview]
Message-ID: <fd29b9a266bef2e480882ba1dc90748c4a12be8c.1478600855.git.nelio.laranjeiro@6wind.com> (raw)
In-Reply-To: <cover.1478600855.git.nelio.laranjeiro@6wind.com>
In-Reply-To: <cover.1478600855.git.nelio.laranjeiro@6wind.com>
From: Nélio Laranjeiro <nelio.laranjeiro@6wind.com>
Make hard-coded values dynamic to return correct link speed capabilities
(not all ConnectX-4 NICs support everything).
Fixes: e274f5732225 ("ethdev: add speed capabilities")
