Saeed Mahameed says: ==================== Mellanox, mlx5e fixes 2018-08-07 I know it is late into 4.18 release, and this is why I am submitting only two mlx5e ethernet fixes. The first one from Or, is needed for -stable and it fixes hairpin for "same device" check. The second fix is a non risk fix from Huy which cleans up and improves error return value reporting for dcbnl_ieee_setapp. For -stable v4.16 - net/mlx5e: Properly check if hairpin is possible between two functions ==================== Signed-off-by: David S.
