We generally default the vendor to y and the drivers itself
to n. NET_DSA_REALTEK, however, selects a whole bunch of things,
so it's not a pure "vendor selection" knob. Let's default it all
to n.

The decision whether to report serdes statistics currently depends on
the cached C_Mode value for the port, read at probe time or updated by
configuration. However, port 4 can be in "automedia" mode when it is
used as a serdes port, meaning it switches between the internal PHY and
the serdes, changing the read-only C_Mode value depending on which
first gains link. Consequently, the C_Mode value read at probe does not
accurately reflect whether the port has the serdes associated with it.
In "net: dsa: mv88e6xxx: add mv88e6352_g2_scratch_port_has_serdes()",
we added a way to read the hardware configuration to determine which
port has the serdes associated with it. Use this to determine which
port reports the serdes statistics.

Given that standalone ports are now configured to bypass the ATU and
forward all frames towards the upstream port, extend the ATU bypass to
multichip systems.
Load VID 0 (standalone) into the VTU with the policy bit set. Since
VID 4095 (bridged) is already loaded, we now know that all VIDs in use
are always available in all VTUs. Therefore, we can safely enable
802.1Q on DSA ports.
Setting the DSA ports' VTU policy to TRAP means that all incoming
frames on VID 0 will be classified as MGMT - as a result, the ATU is
bypassed on all subsequent switches.
With this isolation in place, we are able to support configurations
that are simultaneously very quirky and very useful. Quirky because it
involves looping cables between local switchports like in this
example:
CPU
| .------.
.---0---. | .----0----.
| sw0 | | | sw1 |
'-1-2-3-' | '-1-2-3-4-'
$ @ '---' $ @ % %
We have three physically looped pairs ($, @, and %).
This is very useful because it allows us to run the kernel's
kselftests for the bridge on mv88e6xxx hardware.

A VTU entry with policy enabled is used in combination with a port's
VTU policy setting to override normal switching behavior for frames
assigned to the entry's VID.
A typical example is to Treat all frames in a particular VLAN as
control traffic, and trap them to the CPU. In which case the relevant
user port's VTU policy would be set to TRAP.

Clear MapDA on standalone ports to bypass any ATU lookup that might
point the packet in the wrong direction. This means that all packets
are flooded using the PVT config. So make sure that standalone ports
are only allowed to communicate with the local upstream port.
Here is a scenario in which this is needed:
CPU
| .----.
.---0---. | .--0--.
| sw0 | | | sw1 |
'-1-2-3-' | '-1-2-'
'---'
- sw0p1 and sw1p1 are bridged
- sw0p2 and sw1p2 are in standalone mode
- Learning must be enabled on sw0p3 in order for hardware forwarding
to work properly between bridged ports
1. A packet with SA :aa comes in on sw1p2
1a. Egresses sw1p0
1b. Ingresses sw0p3, ATU adds an entry for :aa towards port 3
1c. Egresses sw0p0
2. A packet with DA :aa comes in on sw0p2
2a. If an ATU lookup is done at this point, the packet will be
incorrectly forwarded towards sw0p3. With this change in place,
the ATU is bypassed and the packet is forwarded in accordance
with the PVT, which only contains the CPU port.

Populate the supported interfaces and MAC capabilities for the xrs700x
family of DSA switches and remove the old validate implementation to
allow DSA to use phylink_generic_validate() for this switch driver.
According to commit ee00b24f32eb ("net: dsa: add Arrow SpeedChips
XRS700x driver") the switch supports one RMII port and up to three
RGMII ports. This commit assumes that port 0 is the RMII port and the
remainder are RGMII.
This commit also results in the Autoneg bit being set in the ethtool
link modes, which wasn't in the original; if this switch supports
RGMII to a 10/100/1G PHY, then surely we want to allow Autoneg on the
PHY.

mgmt Ethernet packet can read/write up to 16byte at times. The len reg
is limited to 15 (0xf). The switch actually sends and accepts data in 4
different steps of len values.
Len steps:
- 0: nothing
- 1-4: first 4 byte
- 5-6: first 12 byte
- 7-15: all 16 byte
In the alloc skb function we check if the len is 16 and we fix it to a
len of 15. It the read/write function interest to extract the real asked
data. The tagger handler will always copy the fully 16byte with a READ
command. This is useful for some big regs like the fdb reg that are
more than 4byte of data. This permits to introduce a bulk function that
will send and request the entire entry in one go.
Write function is changed and it does now require to pass the pointer to
val to also handle array val.

The switch can autocast MIB counter using Ethernet packet.
Add support for this and provide a handler for the tagger.
The switch will send packet with MIB counter for each port, the switch
will use completion API to wait for the correct packet to be received
and will complete the task only when each packet is received.
Although the handler will drop all the other packet, we still have to
consume each MIB packet to complete the request. This is done to prevent
mixed data with concurrent ethtool request.
connect_tag_protocol() is used to add the handler to the tag_qca tagger,
master_state_change() use the MIB lock to make sure no MIB Ethernet is
in progress.

Add qca8k side support for mgmt read/write in Ethernet packet.
qca8k supports some specially crafted Ethernet packet that can be used
for mgmt read/write instead of the legacy method uart/internal mdio.
This add support for the qca8k side to craft the packet and enqueue it.
Each port and the qca8k_priv have a special struct to put data in it.
The completion API is used to wait for the packet to be received back
with the requested data.
The various steps are:
1. Craft the special packet with the qca hdr set to mgmt read/write
mode.
2. Set the lock in the dedicated mgmt struct.
3. Increment the seq number and set it in the mgmt pkt
4. Reinit the completion.
5. Enqueue the packet.
6. Wait the packet to be received.
7. Use the data set by the tagger to complete the mdio operation.
If the completion timeouts or the ack value is not true, the legacy
mdio way is used.
It has to be considered that in the initial setup mdio is still used and
mdio is still used until DSA is ready to accept and tag packet.
tag_proto_connect() is used to fill the required handler for the tagger
to correctly parse and elaborate the special Ethernet mdio packet.
Locking is added to qca8k_master_change() to make sure no mgmt Ethernet
are in progress.

MDIO/MIB Ethernet require the master port and the tagger availabale to
correctly work. Use the new api master_state_change to track when master
is operational or not and set a bool in qca8k_priv.
We cache the first cached master available and we check if other cpu
port are operational when the cached one goes down.
This cached master will later be used by mdio read/write and mib request to
correctly use the working function.
qca8k implementation for MDIO/MIB Ethernet is bad. CPU port0 is the only
one that answers with the ack packet or sends MIB Ethernet packets. For
this reason the master_state_change ignore CPU port6 and only checks
CPU port0 if it's operational and enables this mode.

Before this change, both the read and write callback would start out
by asserting that the chip's busy flag was cleared. However, both
callbacks also made sure to wait for the clearing of the busy bit
before returning - making the initial check superfluous. The only
time that would ever have an effect was if the busy bit was initially
set for some reason.
With that in mind, make sure to perform an initial check of the busy
bit, after which both read and write can rely the previous operation
to have waited for the bit to clear.

Avoid a long delay when a busy bit is still set and has to be polled
again.
Measurements on a system with 2 Opals (6097F) and one Agate (6352)
show that even with this much tighter loop, we have about a 50% chance
of the bit being cleared on the first poll, all other accesses see the
bit being cleared on the second poll.
On a standard MDIO bus running MDC at 2.5MHz, a single access with 32
bits of preamble plus 32 bits of data takes 64*(1/2.5MHz) = 25.6us.
This means that mv88e6xxx_smi_direct_wait took 26us + CPU overhead in
the fast scenario, but 26us + 1500us + 26us + CPU overhead in the slow
case - bringing the average close to 1ms.
With this change in place, the slow case is closer to 2*26us + CPU
overhead, with the average well below 100us - a 10x improvement.
This translates to real-world winnings. On a 3-chip 20-port system,
the modprobe time drops by 88%:
Before:
root@coronet:~# time modprobe mv88e6xxx
real 0m 15.99s

External interfaces can be configured, even if they are not CPU ports.
The first CPU port will also be the trap port (for receiving trapped
frames from the switch).
The CPU information was dropped from chip data as it was not used
outside setup. The only other place it was used is when it wrongly
checks for CPU port when it should check for extint.
The supported modes check now uses port type and not port usage.
As a byproduct, more than one CPU can be configured. although this
might not work well with DSA setups. Also, this driver is still only
blindly forwarding all traffic to CPU port(s).
This change was not tested in a device with multiple active external

"extport" 0, 1, 2 was used to reference external ports id (ext0, ext1,
ext2). Meanwhile, port 0..9 is used as switch ports, including external
ports. "extport" was renamed to extint to make it clear it does not mean
the port number but the external interface number id.
The macros that map extint numbers to registers addresses now use inline
ifs instead of binary arithmetic.
Realtek uses in docs and drivers EXT_PORT0 (GMAC1) and EXT_PORT1
(GMAC2), with EXT_PORT0 being converted to ext_id == 1 and so on. It
might introduce some confusing while reading datasheets but it will not
be exposed to users.
"extint" was hardcoded to 1. However, some chips have multiple external
interfaces. It's not right to assume the CPU port uses extint 1 nor that
all extint are CPU ports. Now it came from a map between port number and
external interface id number.
This patch still does not allow multiple CPU ports nor extint as a non
CPU port.

1. Define more regs. Some switches (e.g. BCM4908) have up to 6 regs.
2. Add helper for handling non-lineral port <-> reg mappings.
3. Add support for 12 B LED reg blocks on BCM4908 (different layout)
Complete support for LEDs setup will be implemented once Linux receives
a proper design & implementation for "hardware" LEDs.

sock.h is pretty heavily used (5k objects rebuilt on x86 after
it's touched). We can drop the include of filter.h from it and
add a forward declaration of struct sk_filter instead.
This decreases the number of rebuilt objects when bpf.h
is touched from ~5k to ~1k.
There's a lot of missing includes this was masking. Primarily
in networking tho, this time.
