Why do you need incremental updates? Doing a PUT with a list of
IP(cidr)/mac is not very expensive to the point were we need to create an
address_pair as a top level resource so you could do what you are doing.
FWIW, the allowed_address_pair attribute works the same way as the
fixed_ips attribute on the port.
