Comment 5 for bug 1077292

Sounds like we have some conflicting text, but the intent as I understood it was that allocation_pools referred to what IPs might be automatically allocated when the creator of a port did not specify any specific fixed_ips. However, any unallocated IP in the subnet could be specified explicitly when creating a port, even if it was not in the allocation_pool. This allowed one to retain a particular subset of the subnet IPs for static allocation.
