Subject: [PATCH mlx5-next v1 1/4] net/mlx5: Declare more strictly devlink encap mode
From: Leon Romanovsky <leonro@...lanox.com>
Devlink has UAPI declaration for encap mode, so there is no
need to be loose on the data get/set by drivers.
Update call sites to use enum devlink_eswitch_encap_mode
instead of plain u8.
