Extend devlink_port_attrs_set() to pass switch ID for ports which are
part of switch and store it in port attrs. For other ports, this is
NULL.
Note that this allows the driver to group devlink ports into one or more
switches according to the actual topology.

When phylink_of_phy_connect fails, dsa_slave_phy_setup tries to save the
day by connecting to an alternative PHY, none other than a PHY on the
switch's internal MDIO bus, at an address equal to the port's index.
However this does not take into consideration the scenario when the
switch that failed to probe an external PHY does not have an internal
MDIO bus at all.

Some drivers are becoming more dependent on NET_DEVLINK being selected

We were skipping the prepare phase which causes some problems with at
least a couple of drivers:
- mv88e6xxx chooses to skip programming VID = 0 with -EOPNOTSUPP in
the prepare phase, but we would still try to force this VID since we
would only call the commit phase and so we would get the driver to
return -EINVAL instead
- qca8k does not currently have a port_vlan_add() callback implemented,
yet we would try to call that unconditionally leading to a NPD
Fix both issues by conforming to the current model doing a
prepare/commit phase, this makes us consistent throughout the code and
assumptions.

In order to properly support VLAN filtering being enabled/disabled on a
bridge, while having other ports being non bridge port members, we need
to support the ndo_vlan_rx_{add,kill}_vid callbacks in order to make
sure the non-bridge ports can continue receiving VLAN tags, even when
the switch is globally configured to do ingress/egress VID checking.
Since we can call dsa_port_vlan_{add,del} with a bridge_dev pointer
NULL, we now need to check that in these two functions.
We specifically deal with two possibly problematic cases:
- creating a bridge VLAN entry while there is an existing VLAN device
claiming that same VID
- creating a VLAN device while there is an existing bridge VLAN entry
with that VID
Those are both resolved with returning -EBUSY back to user-space.

Switches work by learning the MAC address for each attached station by
monitoring traffic from each station. When a station sends a packet,
the switch records which port the MAC address is connected to.
With IPv4 networking, before communication commences with a neighbour,
an ARP packet is broadcasted to all stations asking for the MAC address
corresponding with the IPv4. The desired station responds with an ARP
reply, and the ARP reply causes the switch to learn which port the
station is connected to.
With IPv6 networking, the situation is rather different. Rather than
broadcasting ARP packets, a "neighbour solicitation" is multicasted
rather than broadcasted. This multicast needs to reach the intended
station in order for the neighbour to be discovered.
Once a neighbour has been discovered, and entered into the sending
stations neighbour cache, communication can restart at a point later
without sending a new neighbour solicitation, even if the entry in
the neighbour cache is marked as stale. This can be after the MAC
address has expired from the forwarding cache of the DSA switch -
when that occurs, there is a long pause in communication.
Our DSA implementation for mv88e6xxx switches disables flooding of
multicast and unicast frames for bridged ports. As per the above
description, this is fine for IPv4 networking, since the broadcasted
ARP queries will be sent to and received by all stations on the same
network. However, this breaks IPv6 very badly - blocking neighbour
solicitations and later causing connections to stall.
The defaults that the Linux bridge code expect from bridges are for
unknown unicast and unknown multicast frames to be flooded to all ports
on the bridge, which is at odds to the defaults adopted by our DSA
implementation for mv88e6xxx switches.
This commit enables by default flooding of both unknown unicast and
unknown multicast frames whenever a port is added to a bridge, and
disables the flooding when a port leaves the bridge. This means that
mv88e6xxx DSA switches now behave as per the bridge(8) man page, and
IPv6 works flawlessly through such a switch.

When a DSA port is added to a bridge and brought up, the resulting STP
state programmed into the hardware depends on the order that these
operations are performed. However, the Linux bridge code believes that
the port is in disabled mode.
If the DSA port is first added to a bridge and then brought up, it will
be in blocking mode. If it is brought up and then added to the bridge,
it will be in disabled mode.
This difference is caused by DSA always setting the STP mode in
dsa_port_enable() whether or not this port is part of a bridge. Since
bridge always sets the STP state when the port is added, brought up or
taken down, it is unnecessary for us to manipulate the STP state.
Apparently, this code was copied from Rocker, and the very next day a
similar fix for Rocker was merged but was not propagated to DSA. See

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = alloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = alloc(struct_size(instance, entry, count), GFP_KERNEL)
Notice that, in this case, variable size is not necessary, hence it is
removed.

The unbalance of master's promiscuity or allmulti will happen after ifdown
and ifup a slave interface which is in a bridge.
When we ifdown a slave interface , both the 'dsa_slave_close' and
'dsa_slave_change_rx_flags' will clear the master's flags. The flags
of master will be decrease twice.
In the other hand, if we ifup the slave interface again, since the
slave's flags were cleared the 'dsa_slave_open' won't set the master's
flag, only 'dsa_slave_change_rx_flags' that triggered by 'br_add_if'
will set the master's flags. The flags of master is increase once.
Only propagating flag changes when a slave interface is up makes
sure this does not happen. The 'vlan_dev_change_rx_flags' had the
same problem and was fixed, and changes here follows that fix.

code is insufficient to give clear hints as to the reasons of rejection.
In order to make it possible to communicate the rejection reason, extend
ndo_fdb_add() with an extack argument. Adapt the existing
implementations of ndo_fdb_add() to take the parameter (and ignore it).
Pass the extack parameter when invoking ndo_fdb_add() from rtnl_fdb_add().

There is not currently way to infer the port number through sysfs that
is being used as the CPU port number. Overlay a ndo_get_phys_port_name()
operation onto the DSA master network device in order to retrieve that
information.

In case the destination address is link local, add override bit into the
switch tag to let such a packet through the switch even if the port is
blocked.

Factor out common code from the tag_ksz , so that the code can be used
with other KSZ family switches which use differenly sized tags.

Several conflicts, seemingly all over the place.
I used Stephen Rothwell's sample resolutions for many of these, if not
just to double check my own work, so definitely the credit largely
goes to him.
The NFP conflict consisted of a bug fix (moving operations
past the rhashtable operation) while chaning the initial
argument in the function call in the moved code.
The net/dsa/master.c conflict had to do with a bug fix intermixing of
making dsa_master_set_mtu() static with the fixing of the tagging
attribute location.
cls_flower had a conflict because the dup reject fix from Or
overlapped with the addition of port range classifiction.
__set_phy_supported()'s conflict was relatively easy to resolve
because Andrew fixed it in both trees, so it was just a matter
of taking the net-next copy. Or at least I think it was :-)
Joe Stringer's fix to the handling of netns id 0 in bpf_sk_lookup()
intermixed with changes on how the sdif and caller_net are calculated
in these code paths in net-next.
The remaining BPF conflicts were largely about the addition of the
__bpf_md_ptr stuff in 'net' overlapping with adjustments and additions
to the relevant data structure where the MD pointer macros are used.

A previous change tries to set the MTU on the master device to take

DSA tagging of frames sent over the master interface to the switch
increases the size of the frame. Such frames can then be bigger than
the normal MTU of the master interface, and it may drop them. Use the
overhead information from the tagger to set the MTU of the master
device to include this overhead.

Each DSA tag protocol needs to add additional headers to the Ethernet
frame in order to direct it towards a specific switch egress port. It
must also remove the head from a frame received from a
switch. Indicate the maximum size of these headers in the tag protocol
ops structure, so the core can take these overheads into account.

While introducing the DSA tagging protocol attribute, it was added to the DSA
slave network devices, but those actually see untagged traffic (that is their
whole purpose). Correct this mistake by putting the tagging sysfs attribute
under the DSA master network device where this is the information that we need.
While at it, also correct the sysfs documentation mistake that missed the
"dsa/" directory component of the attribute.

Due to an explicit check in rocker_world_port_obj_vlan_add(),
dsa_slave_switchdev_event() resp. port_switchdev_event(), VLAN objects
that are added to a device that is not a front-panel port device are
ignored. Therefore this check is immaterial.

Drop switchdev_ops.switchdev_port_obj_add and _del. Drop the uses of
this field from all clients, which were migrated to use switchdev
notification in the previous patches.
Add a new function switchdev_port_obj_notify() that sends the switchdev
notifications SWITCHDEV_PORT_OBJ_ADD and _DEL.
Update switchdev_port_obj_del_now() to dispatch to this new function.
Drop __switchdev_port_obj_add() and update switchdev_port_obj_add()
likewise.
