4.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Or Gerlitz <ogerlitz@xxxxxxxxxxxx>
[ Upstream commit c415f704c8276bc686abcb0497bf2606038ca73c ]
On ConnectX5 the wqe inline mode is "none" and hence the FW
reports MLX5_CAP_INLINE_MODE_NOT_REQUIRED.
Fix our devlink callbacks to deal with that on get and set.
Also fix the tc flow parsing code not to fail anything when
inline isn't required.
Fixes: bffaa916588e ('net/mlx5: E-Switch, Add control for inline mode')
