53d688cf85 realtek: dsa: remove storm control
Commit 78bf3a5f44 ("realtek: dsa: Fix rate control initialization") enabled
code setting up the "storm control" feature. This casued a speed regression
on rtl838x, reducing the effective max speed per port from line rate to around
500 Mbits/s.

Storm control is a policy feature with a number of input parameters depending
on use case and environment.  It is not possible to define a meaningful static
policy in the driver. The problem isn't just the arbitrary limits in the
current code.  Such features require userspace interfaces.

Drop this code for now. It wasn't missed while it was disabled.

21414937d1 realtek: dsa: rtl839x: fix uninitialized global access
Setup for DSA QOS on RTL839x accesses unitialized memory. For some
reason the handover of the priv structure was realized via global
intermediate variable switch_priv. During refactoring for adbb9a6
("realtek: dsa: rtl83xx: fix init section mismatch") this was not
noticed. Since then RTL839x devices crash during startup.

Fix this by using standard handover via function parameters.

dec360a3ac realtek: dsa: avoid use-after-free
The realtek target uses some functions marked __init for initialization.
However, that means they can only be called once when compiled in and
afterwards the memory occupied by them is freed and potentially reused.
Some "impossible" (code at a given location can't crash in the way it
does) crashes can be caused by this because upon re-execution of those
functions, garbage gets executed. Such re-execution can happen for
deferred probes or repeated probes.

The GS110TUP's lan9 port is connected via a QSGMII PHY to SERDES 2, and
therefore should use the SWITCH_PORT_SDS macro instead of SWITCH_PORT. This
was missed in e956adfe because the GS110TUP is not particularly well
documented and the old code was confusing.

lan10 is an SFP and doesn't have an onboard PHY, so also remove its
associated PHY references and update it to match other devices' SFP ports.

d8b1a54c78 realtek: pcs: add dedicated enum for SerDes modes
The Realtek SerDes mode capabilities do not map 1:1 to the
PHY_INTERFACE_MODE_* modes used in the kernel and passed to the PCS.
For example, some PHY chips use the proprietary XSGMII mode for which
there isn't an equivalent in the kernel, or HSGMII.

In the past, this led to problems and confusion using kernel's XGMII to
handle the XSGMII mode, and needed a downstream patch for HSGMII. They
have been solved/worked around for now, but XSGMII is currently not
implemented at all. And who knows what might come in the future.

To make our life easier, introduce a dedicated internal representation
of SerDes modes which differs from kernel's PHY_INTERFACE_MODE_*. This
allows us to map "external" modes to different internal modes as needed
instead of carrying the PHY_INTERFACE_MODE_* through the whole SerDes
configuration code. The PCS driver needs to map PHY_INTERFACE_MODE_* to
RTPCS_SDS_MODE_* in pcs_config, and the latter should be used as the
only one.

e989bf80a8 realtek: pcs: drop PCS creation without SerDes ref
Since the beginning, the PCS driver had the ability to call its
rtpcs_create without a reference to a valid PCS node. A comment in the
code mentions that this is done for RTL838X and its built-in octa-PHY
which is connected directly instead of via a SerDes. Further
explanations are not provided.

Drop this ability and make the rtpcs_create call in the dsa driver
conditional. As the built-in PHY of RTL838X isn't attached to a SerDes,
there is no obvious point of having the PCS driver in that chain. The
ports are marked as internal and have no pcs-handle, thus no phylink_pcs
instance should be created.

2e56a1ffc6 realtek: mdio-serdes: improve debugfs creation
Commit 3c073b5cb2 cleaned up the debugfs creation in
mdio-realtek-otto-serdes driver to not explicitly check if the root
directory already exists. This is fine because kernel handles the case
properly so there's no need to check anymore.

However, this pollutes the boot log with:
[..] debugfs: 'realtek_otto_serdes' already exists in '/'
[..] debugfs: 'realtek_otto_serdes' already exists in '/'
[..] debugfs: 'realtek_otto_serdes' already exists in '/'
[..] debugfs: 'realtek_otto_serdes' already exists in '/'
[..] debugfs: 'realtek_otto_serdes' already exists in '/'
[..] debugfs: 'realtek_otto_serdes' already exists in '/'
[..] debugfs: 'realtek_otto_serdes' already exists in '/'
[..] debugfs: 'realtek_otto_serdes' already exists in '/'
[..] debugfs: 'realtek_otto_serdes' already exists in '/'
[..] debugfs: 'realtek_otto_serdes' already exists in '/'
[..] debugfs: 'realtek_otto_serdes' already exists in '/'

Now, the root directory creation is attempted multiple times, causing
the kernel to print an error message because the directory already
exists.

Fix this by moving the SerDes loop into rtsds_debug_init and only try
to create the root debugfs directory once.

RTL838X SerDes is now completely managed by the PCS driver so it's time

e956adfe3e realtek: rtl838x: setup SDS entirely in PCS driver
After having moved the configuration code and sequences from PHY and
DSA drivers to the PCS driver, add the hooks in PCS driver and remove
calls in PHY and DSA drivers to let PCS driver setup the SerDes
entirely on its own.

Also add pcs-handle to device tree definitions for most of the switch
ports because, due to the refactoring of the SerDes configuration, this
is needed now for all SerDes-attached ports.

b670d48366 realtek: pcs: rtl838x: refactor imported code
The previous commit just imported some code as-is and commented it.
It needs heavy adjustments to compile and work within the PCS driver.
Do that now to that extent that it can be used within the driver. More
cosmetics and improvements will be done later.

Split the once-for-all SerDes configuration into the usual flow where
each SerDes is configured separately and on its own, as requested by the
PCS subsystem.

Move mode setting and patching into proper functions which are called
during SerDes configuration. Some configuration sequences are broken up
and moved into the SerDes configuration flow, e.g. reset sequences
because they were usually a single/few values applied to all SerDes at
once before.

Add proper configuration for SerDes 4 QSGMII to be able to setup this
mode properly on our own.

The code needs heavy adjustments to make it compile and work. To make

6a5cae7d74 realtek: pcs: rtl838x: transplant firmware config
In the PHY driver, firmware files were used to store configuration
values for the SerDes which need to be applied upon initialization.
There are several issues which prevent to just take that over into the
PCS driver:
* SerDes and PHY parts are mixed within a firmware file
* SerDes access in PHY driver is based on writing into the switch's
  global register space; PCS driver uses access via MDIO interface
  --> destination values do not match
* firmware file format is not SerDes-agnostic
* no documentation or script for the "old" firmware files

Unfortunately, there is no proper firmware format yet where to take over
the required sequences. Thus, extract the sequences needed for RTL838X
SerDes, transform them to work with the MDIO based access and put them
as functions in the PCS driver.

Note that this should just be a temporary solution. In a next step, a
proper firmware format should be established and all configuration
sequences currently in the code should be moved into firmware files.

328b970ecd realtek: pcs: add init_serdes_common hook
Add a new hook called 'init_serdes_common' to be able to perform
initialisations or anything else subject to all SerDes. This hook is
called in the end of 'rtpcs_probe' after everything else is done.

This is meant primarily to support the transition of RTL83XX from PHY
driver to PCS driver. Thus, it may be removed later again or kept if
there is sufficient need for this.

c9553caa0e realtek: fix SFP support on Engenius EWS2910P
Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
EWS2910P has two SFP slots of which only one was fully supported so far.
The issue so far was that both SFP slots share the same I2C SCL line but
neither the kernel nor any downstream driver was able to deal with this.

Thus, only one SFP slot was completely working (with detection etc.) but
the other one had to be enabled manually. Networking was functional in
both though.

Since acd7ecc9ed we have a driver which is able to deal with that. Thus,
we can fix the SFP support for this device.

141ac0b2bd realtek: dsa: rtl930x: Fix flow control with ingress shaping
Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
Tests with ingress shaping and enabled flow control showed really high
packet loss. It seems like the MAC pause frames are not created correctly
when both burst high off is set to the same value as burst high on.

By default, RTL930x has set the burst high values to:

* on: 64K
* off: 32K

Using the same 1:2 ratio seems to solve the high packet loss rate during
UDP tests.
