Subject: [PATCH 4.9 054/108] net/mlx5: E-Switch, Err when retrieving steering name-space fails

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

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

From: Or Gerlitz <ogerlitz@...lanox.com>


[ Upstream commit 5403dc703ff277f8a2a12a83ac820750485f13b3 ]

Make sure to return error when we failed retrieving the FDB steering
name space. Also, while around, correctly print the error when mode
change revert fails in the warning message.
