Why do we need encap and decap?

What is the l3_type used for?

Why vlan has dedicated variable?

Why assert on the item? It should be valid and if not return error.

> +	*size = 0;

Why not use temp_size and avoid memory access?

Why TODO?

This can result in crash if type is not the one you expected.

Why cast to void? Same for all others.
