[Bug 1653633] [NEW] fwaas v1 with DVR: l3 agent can't restore the NAT rules for floatingIP

 

Public bug reported:

With neutron and FWaas master branch and in DVR mode, I create a VM with
floatingIP, it works ok, but when i restart the related l3-agent, i
can't reach the VM via FloatingIP, then check the NAT rules in router
namespace, i found the NAT rules did not be restored.

reproduce steps:
1. in DVR mode
2. create a VM with floatingIP
3. restart the related l3 agent on compute node
we can check that the NAT rule for floatingIP did not be restored.
