Before introducing support for L3 interfaces on top of the VLAN-aware
bridge we need to add some missing infrastructure.
Such an interface can either be the bridge device itself or a VLAN
device on top of it. In the first case the router interface (RIF) is
associated with FID 1, which is created whenever the first port netdev
joins the bridge. We currently assume the default PVID is 1 and that
it's already created, as it seems reasonable. This can be extended in
the future.
However, in the second case it's entirely possible we've yet to create a
matching FID. This can happen if the VLAN device was configured before
making any bridge port member in the VLAN.
Prevent such ordering problems by using the VLAN device's CHANGEUPPER
event to configure the FID. Make the VLAN device hold a reference to the
FID and prevent it from being destroyed even if none of the port netdevs
is using it.

Up until now we only supported bridged interfaces. Packets ingressing
through the switch ports were either classified to FIDs (in the case of
the VLAN-aware bridge) or vFIDs (in the case of VLAN-unaware bridges).
The packets were then forwarded according to the FDB. Routing was done
entirely in slowpath, by splitting the vFID range in two and using the
lower 0.5K vFIDs as dummy bridges that simply flooded all incoming
traffic to the CPU.
Instead, allow packets to be routed in the device by creating router
interfaces (RIFs) that will direct them to the router block.
Specifically, the RIFs introduced here are Sub-port RIFs used for VLAN
devices and port netdevs. Packets ingressing from the {Port / LAG ID, VID}
with which the RIF was programmed with will be assigned to a special
kind of FIDs called rFIDs and from there directed to the router.
Create a RIF whenever the first IPv4 address was programmed on a VLAN /
LAG / port netdev. Destroy it upon removal of the last IPv4 address.
Receive these notifications by registering for the 'inetaddr'
notification chain. A non-zero (10) priority is used for the
notification block, so that RIFs will be created before routes are
offloaded via FIB code.
Note that another trigger for RIF destruction are CHANGEUPPER
notifications causing the underlying FID's reference count to go down to
zero. This can happen, for example, when a VLAN netdev with an IP address
is put under bridge. While this configuration doesn't make sense it does
cause the device and the kernel to get out of sync when the netdev is
unbridged. We intend to address this in the future, hopefully in current
cycle.
Finally, Remove the lower 0.5K vFIDs, as they are deprecated by the RIFs,
which will trap packets according to their DIP.

We are just about to introduce router interfaces (RIFs), but before that
we need to be able update the device with the correct RIF attributes
whenever they change for the netdev the RIF is backing. Two such
attributes are MTU and MAC.
The MAC is used both to set the source MAC of packets egressing from the
RIF and also to program an FDB rule that will direct packets to the
router block.
Use the existing netdevice notification block and respond to CHANGEADDR
and CHANGEMTU accordingly. Store both attributes in the RIF struct

FDB entries are learned using {Port / LAG ID, FID} and therefore should
be flushed whenever a port (vPort) leaves its FID (vFID).
However, when the bridge port is a LAG device (or a VLAN device on top),
then FDB flushing is conditional. Ports removed from such LAG
configurations must not trigger flushing, as other ports might still be
members in the LAG and therefore the bridge port is still active.
The decision whether to flush or not was previously computed in the
netdevice notification block, but in order to flush the entries when a
port leaves its FID this decision should be computed there.
Strip the notification block from this logic and instead move it to one
FDB flushing function that is invoked from both the FID / vFID leave
functions.
When port isn't member in LAG, FDB flushing should always occur.
Otherwise, it should occur only when the last port (vPort) member in the
LAG leaves the FID (vFID).
This will allow us - in the next patch - to simplify the cleanup code
paths that are hit whenever the topology above the port netdevs changes.

In a very similar way to the vFIDs, make the first 4K FIDs - used in the
VLAN-aware bridge - use the new FID struct.
Upon first use of the FID by any of the ports do the following:
1) Create the FID
2) Setup a matching flooding entry
3) Create a mapping for the FID
Unlike vFIDs, upon creation of a FID we always create a global
VID-to-FID mapping, so that ports without upper vPorts can use it
instead of creating an explicit {Port, VID} to FID mapping.
When a port leaves a FID the reverse is performed. Whenever the FID's
reference count reaches zero the FID is deleted along with the global
mapping.
The per-FID struct will later allow us to configure L3 interfaces on top
of the VLAN-aware bridge.

Up until now we had a dedicated struct only for vFIDs, but before
introducing support for L3 interfaces we need to make it generic and
use it for all three types of FIDs:
1) FIDs - 0..4K-1, used for the VLAN-aware bridge
2) vFIDs - 4K..15K-1, used for VLAN-unaware bridges
3) rFIDs - 15K..16K-1, used to direct traffic to / from the router in
the device. Will be introduced later in the series.
The three types of L3 interfaces - Router InterFaces, RIFs - that will
be introduced correspond to the three types of FIDs and are configured
using them. Therefore, we'll need to store the links between them as
well as a reference count on the underlying FID, so that the
corresponding RIF will be destroyed when it reaches zero.
Note that the lower 0.5K vFIDs are currently used for for non-bridged
netdevs, so that traffic could be flooded to the CPU port. However, when
rFIDs will be introduced we'll no longer need these and they too will be
used for VLAN-unaware bridges.
Make the vFID struct generic by renaming it and some of its fields. FIDs
will be converted to use it later in the series.

All the member VLAN devices in a bridge need to share the same vFID.
To achieve that, expand the vFID struct to include the associated bridge
device (or lack of) and allow one to lookup a vFID based on a bridge
device.
When joining a bridge, lookup the relevant vFID or create one if none
exists. Next, make the VLAN device use the vFID.
Leaving a bridge can either occur because a user removed the VLAN device
from a bridge or because the VLAN device was deleted by the user. In the
latter case the bridge's teardown sequence is invoked after the hardware
vPort is already gone. Therefore, when unlinking the VLAN device from
the real device, check if the associated vPort is bridged and act
accordingly. The bridge's notification will be ignored in this case.
Note that bridging a VLAN interface with an ordinary port netdev is
currently not supported, but not forbidden. This will be addressed in a
