Full rate small packets would be an attack of some kind and could only
realistically arrive at your transit and peering ports. The customers
usually have slower (relatively) ports and a single customer could not
produce a rate of small packets that would be a concern. Therefore uRPF at
customer ports should not be a problem in this regard.
