Netfilter tables (nftables) implements a software datapath that
comes after tc ingress datapath. The datapath supports offloading
such rules via the flow table offload API.
This API is currently only used by NFT and it doesn't provide the
global priority in regards to tc offload, so we assume offloading such
rules must come after tc. It does provide a flow table priority
parameter, so we need to provide some supported priority range.
For that, split fastpath prio to two, flow table offload and tc offload,
with one dedicated priority chain for flow table offload.
Next patch will re-use the multi chain API to access this chain by
allowing access to this chain by the fdb_sub_namespace.

Tc chains are implemented by creating a chained prio steering type, and
inside it there is a namespace for each chain (FDB_TC_MAX_CHAINS). Each
of those has a list of priorities.
Currently, all namespaces in a prio start at the parent prio level.
But since we can jump from chain (namespace) to another chain in the
same prio, we need the levels for higher chains to be higher as well.
So we created unused prios to account for levels in previous namespaces.
Fix that by accumulating the namespaces levels if we are inside a chained
type prio, and removing the unused prios.

VSC7514 is a 10-port switch with 2 extra "CPU ports" (targets in the
queuing subsystem for terminating traffic locally).
There are 2 issues with hardcoding the CPU port as #10:
- It is not clear which snippets of the code are configuring something
for one of the CPU ports, and which snippets are just doing something
related to the number of physical ports.
- Actually any physical port can act as a CPU port connected to an
external CPU (in addition to the local CPU). This is called NPI mode
(Node Processor Interface) and is the way that the 6-port VSC9959
(Felix) switch is integrated inside NXP LS1028A (the "local management
CPU" functionality is not used there).
This patch makes it clear that the ocelot_bridge_stp_state_set function
operates on the CPU port (by making it an implicit member of the
bridging domain), and at the same time adds logic for the NPI port (aka
a physical port) to play the role of a CPU port (it shouldn't be part of
bridge_fwd_mask, as it's not explicitly enslaved to a bridge).

The ocelot and ocelot_port structures will be used by a new DSA driver,
so the ocelot_board.c file will have to allocate and work with a private
structure (ocelot_port_private), which embeds the generic struct
ocelot_port. This is because in DSA, at least one interface does not
have a net_device, and the DSA driver API does not interact with that
anyway.
The ocelot_port structure is equivalent to dsa_port, and ocelot to
dsa_switch. The members of ocelot_port which have an equivalent in
dsa_port (such as dp->vlan_filtering) have been moved to
ocelot_port_private.
We want to enforce the coding convention that "ocelot_port" refers to
the structure, and "port" refers to the integer index. One can retrieve
the structure at any time from ocelot->ports[port].
The patch is large but only contains variable renaming and mechanical
