[PATCH 4.19 25/42] net/mlx5e: Removed unnecessary warnings in FEC caps query

[Greg Kroah-Hartman]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Shay Agroskin <shayag@xxxxxxxxxxxx>

[ Upstream commit 64e283348458e2fd2fe41b60dfb6c30e88ee695f ]

Querying interface FEC caps with 'ethtool [int]' after link reset
throws warning regading link speed.
This warning is not needed as there is already an indication in
user space that the link is not up.

Fixes: 0696d60853d5 ("net/mlx5e: Receive buffer configuration")
