Comment 11 for bug 1843211

Hi, all:
I am so sorry, I absent the neutron driver meeting yesterday because of terrible network environment. But I read the meeting record[1].

yamamoto: This bug is reported by our QA team. Usually, I don't agree a subnet without allocation pools. But, updating of allocation pools is useful, it can help user to control the allocation of ip address. So, this maybe results in the "total_ips" < "used_ips", this will cause some confusion to the users.
