====================
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
