Please arrange these structure members in a more optimal order so that
the resulting object is denser. For example, in switchdev_obj_in_role_mrp
if you order it such that:
> + u32 ring_id;
> + u16 in_id;
> + u8 in_role;
You'll have less wasted space from padding.
Use 'pahole' or similar tools to guide you.
