L3 agent fetches the external network id once
Rather than fetching the id of the external network each time that
_process_routers is called, get it once and remember it. If the agent
is ever requested to connect to a different ext-net then it will fetch
the current ext-net to double check for the unlikely event that the
ext-net has changed. If it has then it will remember the new ext-net.
This is only applicable in the case where there is only one ext-net
that has not been configured explicitly in the config file. That was
the only case that would cause an RPC message in the first place.
This patch changes get_vif_port_set in order to not return
OVS ports for which the ofport is not yet assigned, thus avoiding
a regex match failure in get_vif_port_by_id.
Because of this failure, treat_vif_port is unable to wire
the port.
As get_vif_port_by_id is also used elsewhere in the agent, it has
been enhanced in order to tolerate situations in which ofport might
have not yet been assigned.
The ofport field is added to the list of those monitored by the
SimpleInterfaceMonitor. This will guarantee an event is generated
when the ofport is assigned to a port. Otherwise there is a risk
a port would be never processed if it was not yet ready the first
time is was detected. This change won't trigger any extra processing
on the agent side.
Finally, this patch avoids fetching device details from the plugin
for ports which have disappeared from the OVS bridge. This is a
little optimization which might be beneficial for short lived ports.

Add migration support from agent to NSX dhcp/metadata services
This is feature patch (3 of 3) that introduces support for
transitioning existing NSX-based deployments from the agent
based model of providing dhcp and metadata proxy services
to the new agentless based mode. In 'combined' mode, existing
networks will still be served by the existing infrastructure,
whereas new networks will be served by the new infrastructure.
Networks may be migrated to the model using a new CLI tool
provided, called 'neutron-nsx-manage'. Currently the tool
provides two admin-only commands:
neutron-nsx-manage net-report <net-id-or-name>
This will check that the network can be migrated and returns
the resources currently in use. And:
neutron-nsx-manage net-migrate <net-id-or-name>
This will move the network over the new model and deallocate
resources from the agent. Once a network has been migrated
there is no turning back.
The NSX plugin does not allow to reassociate a floating IP to
a different internal IP address on the same port where it's
currently associated.
This patch fixes this behaviour and adds a unit test to ensure
re-association on the same port with a different IP is possible.

accomodate the newly introduced unit test.

Add an explicit tox job for functional tests
This change is in support of adding a new jenkins job dedicated

In the majority of cases a port_update notification pertains
a change in the properties affecting port filter, and does
not affect port wiring, ie: the local vlan tag.
This patch simply avoids doing port wiring/unwiring if the
local vlan tag did not change.
The extra overhead for the ovs-db get operation is offset
by the fact that get commands are generally faster than
set commands, and by avoiding executing the ovs-ofctl operation.
Process port_update notifications in the main agent loop
Instead of processing a port update notification directly in
the RPC call, the actual processing is moved into the main
rpc loop, whereas the RPC call just adds the updated port
identifier to a set of updated ports.
In this way, a port_update notification won't compete with the
main rpc loop, causing long delays into its completion under
heavy load. Also, repeated port_update notifications received
within a single iteration of the main agent loop will be
coalesced and processed only once.
This will also avoid the risk of processing notifications out
of order thus ending up with an actual configuration which
differs from the desired one.
This patch still performs L2 wiring for updated ports even if
it is necessary only when the administrative state of a port
changes.

name appears to be more in line with what the method actually does.

Simplify ip allocation/recycling to relieve db pressure
I found that multiple calls to delete_port can pile up on the
_recycle_ip operation. This patch simplifies this operation. It
reduces the _recycle_ip operation to a single row delete in the ip
allocations table and doesn't touch the availability table.
To acheive the recycling of ips in a pool, this code runs a more
complex operation of rebuilding the availability table when it is
exhausted. Only one API process will perform this more expensive
operation and others waiting for allocation will immediately benefit.
The amortized cost of this operation is much less than the cumulative
cost of running the more expensive _recycle_ip operation for every
port delete.
IP allocation behaves a bit differently with this patch. Instead of
giving out the first IP available in a pool, the entire pool will be
allocated before wrapping around and recycling ip addresses that have
been released. This is a desirable feature as it puts ip addresses in
a sort of quarantine after they are released. It is easier to
distinguish newly allocated ips from old ones.
