Title:
  while bringing up the neutron network on the openstack kilo, virtual
  swtich internal bridges values might be greater than 4094

Status in neutron:
  Expired

Bug description:
  On Kilo, we have the following issue.
  When newtron comes up, the bridges come up with value of 4095, which is out of range of 0-4094
  Due to this the instance never comes up.
  Once we delete and re-create it, it comes up fine
