    Process port IP requests before subnet requests

    When a port requests multiple fixed IPs, process the requests
    for specific IP addresses before the ones asking for a subnet.
    This prevents an error where the IP that was requested happens
    to be the next up for allocation so the subnet request takes it
    and causes a DBDuplicateEntry.
