[PATCH for v4.9 LTS 058/111] net/mlx5: E-Switch, Err when retrieving steering name-space fails

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Or Gerlitz <ogerlitz@xxxxxxxxxxxx>

[ 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.
