Public bug reported:
If the DVR+HA router has external gateway, the snat-namespace will be
initialized twice during agent restart.
And that initialized function will run many [1][2] external resource processing

Public bug reported:
For one network with multiple slaac IPv6 subnets, the created port will have
all IPv6 subnets address automatically by default. For some use case, we do not
want the port to have all the IPv6 address from all IPv6 subnets, but only one
of it. It is a behavior for neutron no

RPC timeout can be found frequently, but we have no statistical data for
it. A simple log can help. Since all the projects are using

Public bug reported:
When port installed to the agent, it will be processed in rpc_loop X as
"added". In next X + 1 rpc_loop, it will be processed again as
"updated". This is unnecessary. And it can highly probably increase the
processing time of new "added" ports in this X+1 loop.
