Comment 9 for bug 1843211

Proposal from yangjianfeng makes sense for me. We can use IMO "total_ips" as number of all IPs in subnet - so IP addresses which user can manually use to create ports (see comment #4 from Akihiro). And new field with number of IPs available to allocate automatically could be added to this list also.
Let's discuss that on next drivers team meeting.
