For addr: this field is not used, since buffer select is forced.
But by forcing it to be zero it leaves open future uses of the field.

len is actually usable, you could imagine that you want to receive
multishot up to a certain length.
However right now this is not how it is implemented, and it seems
safer to force this to be zero.
