Hi Saeed,

I see that Dave is already applied it, so my comment is mostly for
future submission. This patch went to a right direction by reducing
export symbol pollution, but left function declarations in globally
visible include/linux/mlx5/vport.h header file.

Such situation leaves the mlx5 driver in limbo state
where mlx5_ib have access to those functions but can't use them.

Care to send followup patch to fix it?
