Hello again;
I recently tried to fire up an instance and networking didn't work.  I
looked at the neutron logs and found this.

2017-10-24 15:57:10.565 1784 ERROR neutron.agent.linux.utils
[req-bbe542d2-7d02-4373-b6af-4f8ee3dd6392 - - - - -]

ifconfig shows this exists, and it's my host machine.  This is out of range
of the Openstack DHCP that I set up.

brq9ee73442-5a: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 172.22.10.99  netmask 255.255.255.0  broadcast 172.22.10.255
        ether 00:00:00:00:00:00  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 11  bytes 2027 (1.9 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Everything used to work.  I wonder what has changed.  Why would neutron try
to create a port at "99" (if indeed that's what's happening).

Finally, my subnet info for public.
Could I have made a mistake here?
