net: ethernet: ocelot: remove the need for num_stats initializer

There is a desire to share the oclot_stats_layout struct outside of the
current vsc7514 driver. In order to do so, the length of the array needs to
be known at compile time, and defined in the struct ocelot and struct
felix_info.

Since the array is defined in a .c file and would be declared in the header
file via:
extern struct ocelot_stat_layout[];
the size of the array will not be known at compile time to outside modules.

To fix this, remove the need for defining the number of stats at compile
time and allow this number to be determined at initialization.

net: mscc: ocelot: don't add VID 0 to ocelot->vlans when leaving VLAN-aware bridge

DSA, through dsa_port_bridge_leave(), first notifies the port of the
fact that it left a bridge, then, if that bridge was VLAN-aware, it
notifies the port of the change in VLAN awareness state, towards
VLAN-unaware mode.

So ocelot_port_vlan_filtering() can be called when ocelot_port->bridge
is NULL, and this makes ocelot_add_vlan_unaware_pvid() create a struct
ocelot_bridge_vlan with a vid of 0 and an "untagged" setting of true on
that port.

In a way this structure correctly reflects the reality, but by design,
VID 0 (OCELOT_STANDALONE_PVID) was not meant to be kept in the bridge
VLAN list of the driver, but managed separately.

Having OCELOT_STANDALONE_PVID in ocelot->vlans makes us trip up on
several sanity checks that did not expect to have this VID there.
For example, after we leave a VLAN-aware bridge and we re-join it, we
can no longer program egress-tagged VLANs to hardware:

# ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up
# ip link set swp0 master br0
# ip link set swp0 nomaster
# ip link set swp0 master br0
# bridge vlan add dev swp0 vid 100
Error: mscc_ocelot_switch_lib: Port with more than one egress-untagged VLAN cannot have egress-tagged VLANs.

But this configuration is in fact supported by the hardware, since we
could use OCELOT_PORT_TAG_NATIVE. According to its comment:

/* all VLANs except the native VLAN and VID 0 are egress-tagged */

yet when assessing the eligibility for this mode, we do not check for
VID 0 in ocelot_port_uses_native_vlan(), instead we just ensure that
ocelot_port_num_untagged_vlans() == 1. This is simply because VID 0
doesn't have a bridge VLAN structure.

The way I identify the problem is that ocelot_port_vlan_filtering(false)
only means to call ocelot_add_vlan_unaware_pvid() when we dynamically
turn off VLAN awareness for a bridge we are under, and the PVID changes
from the bridge PVID to a reserved PVID based on the bridge number.

Since OCELOT_STANDALONE_PVID is statically added to the VLAN table
during ocelot_vlan_init() and never removed afterwards, calling
ocelot_add_vlan_unaware_pvid() for it is not intended and does not serve
any purpose.

Fix the issue by avoiding the call to ocelot_add_vlan_unaware_pvid(vid=0)
when we're resetting VLAN awareness after leaving the bridge, to become
a standalone port.

net: mscc: ocelot: ignore VID 0 added by 8021q module

Both the felix DSA driver and ocelot switchdev driver declare
dev->features & NETIF_F_HW_VLAN_CTAG_FILTER under certain circumstances*,
so the 8021q module will add VID 0 to our RX filter when the port goes
up, to ensure 802.1p traffic is not dropped.

We treat VID 0 as a special value (OCELOT_STANDALONE_PVID) which
deliberately does not have a struct ocelot_bridge_vlan associated with
it. Instead, this gets programmed to the VLAN table in ocelot_vlan_init().

If we allow external calls to modify VID 0, we reach the following
situation:

# ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up
# ip link set swp0 master br0
# ip link set swp0 up # this adds VID 0 to ocelot->vlans with untagged=false
bridge vlan
port vlan-id
swp0 1 PVID Egress Untagged # the bridge also adds VID 1
br0 1 PVID Egress Untagged
# bridge vlan add dev swp0 vid 100 untagged
Error: mscc_ocelot_switch_lib: Port with egress-tagged VLANs cannot have more than one egress-untagged (native) VLAN.

This configuration should have been accepted, because
ocelot_port_manage_port_tag() should select OCELOT_PORT_TAG_NATIVE.
Yet it isn't, because we have an entry in ocelot->vlans which says
VID 0 should be egress-tagged, something the hardware can't do.

Fix this by suppressing additions/deletions on VID 0 and managing this
VLAN exclusively using OCELOT_STANDALONE_PVID.

*DSA toggles it when the port becomes VLAN-aware by joining a VLAN-aware
bridge. Ocelot declares it unconditionally for some reason.

net: mscc: ocelot: fix broken IP multicast flooding

When the user runs:
bridge link set dev $br_port mcast_flood on

this command should affect not only L2 multicast, but also IPv4 and IPv6
multicast.

In the Ocelot switch, unknown multicast gets flooded according to
different PGIDs according to its type, and PGID_MC only handles L2
multicast. Therefore, by leaving PGID_MCIPV4 and PGID_MCIPV6 at their
default value of 0, unknown IP multicast traffic is never flooded.
