Currently the ocelot switch lib is unaware of the index of a struct
ocelot_port, since that is kept in the encapsulating structures of outer
drivers (struct dsa_port :: index, struct ocelot_port_private :: chip_port).
With the upcoming increase in complexity associated with assigning DSA
tag_8021q CPU ports to certain user ports, it becomes necessary for the
switch lib to be able to retrieve the index of a certain ocelot_port.
Therefore, introduce a new u8 to ocelot_port (same size as the chip_port
used by the ocelot switchdev driver) and rework the existing code to
populate and use it.

The error handling for the current tagging protocol change procedure is
a bit brittle (we dismantle the previous tagging protocol entirely
before setting up the new one). By identifying which parts of a tagging
protocol are unique to itself and which parts are shared with the other,
we can implement a protocol change procedure where error handling is a
bit more robust, because we start setting up the new protocol first, and
tear down the old one only after the setup of the specific and shared
parts succeeded.
The protocol change is a bit too open-coded too, in the area of
migrating host flood settings and MDBs. By identifying what differs
between tagging protocols (the forwarding masks for host flooding) we
can implement a more straightforward migration procedure which is
handled in the shared portion of the protocol change, rather than
individually by each protocol.
Therefore, a more structured approach calls for the introduction of a
structure of function pointers per tagging protocol. This covers setup,
teardown and the host forwarding mask. In the future it will also cover
how to prepare for a new DSA master.
The initial tagging protocol setup (at driver probe time) and the final
teardown (at driver removal time) are also adapted to call into the
structured methods of the specific protocol in current use. This is
especially relevant for teardown, where we previously called
felix_del_tag_protocol() only for the first CPU port. But by not
specifying which CPU port this is for, we gain more flexibility to
support multiple CPU ports in the future.

Ocelot switches support a single active CPU port at a time (at least as
a trapping destination, i.e. for control traffic). This is true
regardless of whether we are using the native copy-to-CPU-port-module
functionality, or a redirect action towards the software-defined
tag_8021q CPU port.
Currently we assume that the trapping destination in tag_8021q mode is
the first CPU port, yet in the future we may want to migrate the user
ports to the second CPU port.
For that to work, we need to make sure that the tag_8021q trapping
destination is a CPU port that is active, i.e. is used by at least some
user port on which the trap was added. Otherwise, we may end up
redirecting the traffic to a CPU port which isn't even up.
Note that due to the current design where we simply choose the CPU port
of the first port from the trap's ingress port mask, it may be that a
CPU port absorbes control traffic from user ports which aren't affine to
it as per user space's request. This isn't ideal, but is the lesser of
two evils. Following the user-configured affinity for traps would mean
that we can no longer reuse a single TCAM entry for multiple traps,
which is what we actually do for e.g. PTP. Either we duplicate and
deduplicate TCAM entries on the fly when user-to-CPU-port mappings
change (which is unnecessarily complicated), or we redirect trapped
traffic to all tag_8021q CPU ports if multiple such ports are in use.
The latter would have actually been nice, if it actually worked, but it
doesn't, since a OCELOT_MASK_MODE_REDIRECT action towards multiple ports
would not take PGID_SRC into consideration, and it would just duplicate
the packet towards each (CPU) port, leading to duplicates in software.

DSA has not supported (and probably will not support in the future
either) independent tagging protocols per CPU port.
Different switch drivers have different requirements, some may need to
replicate some settings for each CPU port, some may need to apply some
settings on a single CPU port, while some may have to configure some
global settings and then some per-CPU-port settings.
In any case, the current model where DSA calls ->change_tag_protocol for
each CPU port turns out to be impractical for drivers where there are
global things to be done. For example, felix calls dsa_tag_8021q_register(),
which makes no sense per CPU port, so it suppresses the second call.
Let drivers deal with replication towards all CPU ports, and remove the
CPU port argument from the function prototype.

At the time - commit 7569459a52 ("net: dsa: manage flooding on the CPU
ports") - not introducing a dedicated switch callback for host flooding
made sense, because for the only user, the felix driver, there was
nothing different to do for the CPU port than set the flood flags on the
CPU port just like on any other bridge port.
There are 2 reasons why this approach is not good enough, however.
(1) Other drivers, like sja1105, support configuring flooding as a
function of {ingress port, egress port}, whereas the DSA
->port_bridge_flags() function only operates on an egress port.
So with that driver we'd have useless host flooding from user ports
which don't need it.
(2) Even with the felix driver, support for multiple CPU ports makes it
difficult to piggyback on ->port_bridge_flags(). The way in which
the felix driver is going to support host-filtered addresses with
multiple CPU ports is that it will direct these addresses towards
both CPU ports (in a sort of multicast fashion), then restrict the
forwarding to only one of the two using the forwarding masks.
Consequently, flooding will also be enabled towards both CPU ports.
However, ->port_bridge_flags() gets passed the index of a single CPU
port, and that leaves the flood settings out of sync between the 2
CPU ports.
This is to say, it's better to have a specific driver method for host
flooding, which takes the user port as argument. This solves problem (1)
by allowing the driver to do different things for different user ports,
and problem (2) by abstracting the operation and letting the driver do
whatever, rather than explicitly making the DSA core point to the CPU
port it thinks needs to be touched.
This new method also creates a problem, which is that cross-chip setups
are not handled. However I don't have hardware right now where I can
test what is the proper thing to do, and there isn't hardware compatible
with multi-switch trees that supports host flooding. So it remains a
problem to be tackled in the future.
