So from a user symptom / impact standpoint, when new instances are nova
booted, they are able to send DHCP DISCOVER packet through the
corresponding bridge, but return DHCP OFFER traffic never reaches the
new instance.

In all cases that I have seen, the neutron net, subnet, and port
statuses all report A-OK via cli queries.  In some cases, inspecting the
new underlying bridge with brctl results in error(s), but not always.

## Symptomatic info re: bridge:
$ sudo brctl show qvob744fc12-71
bridge name     bridge id               STP enabled     interfaces
qvob744fc12-71          can't get info Operation not supported

$ sudo brctl showmacs qvob744fc12-71 
read of forward table failed: Operation not supported

## Symptomatic info from nova console-log:
