Hello,

I assume most of the time or maybe always the for-loop reduces to a single
function call, either ip_forward or ip_local_deliver.
(see ip_route_input_slow, watch out for rth->u.dst.input = ...)

Maybe someone else can explain, if there are scenarios where more that
one dst input function comes into play or whether it was just done to
keep it analog to dst_output ...?
