Add icssg_stats.c to help dump, icssg related driver statistics.
ICSSG has hardware registers for providing statistics like total rx bytes,
total tx bytes, etc. These registers are of 32 bits and hence in case of 1G
link, they overflows in around 32 seconds. The behaviour of these registers
is such that they don't roll back to 0 after overflow but rather stay at
UINT_MAX.
These registers support a feature where the value written to them is
subtracted from the register. This feature can be utilized to fix the
overflowing of stats.
This solution uses a Workqueues based solution where a function gets
called before the registers overflow (every 25 seconds in 1G link, 25000
seconds in 100M link), this function saves the register
values in local variables and writes the last read value to the
register. So any update during the read will be taken care of.

This is the Ethernet driver for TI AM654 Silicon rev. 2
with the ICSSG PRU Sub-system running dual-EMAC firmware.
The Programmable Real-time Unit and Industrial Communication Subsystem
Gigabit (PRU_ICSSG) is a low-latency microcontroller subsystem in the TI
SoCs. This subsystem is provided for the use cases like implementation of
custom peripheral interfaces, offloading of tasks from the other
processor cores of the SoC, etc.
Every ICSSG core has two Programmable Real-Time Unit(PRUs),
two auxiliary Real-Time Transfer Unit (RT_PRUs), and
two Transmit Real-Time Transfer Units (TX_PRUs). Each one of these runs
its own firmware. Every ICSSG core has two MII ports connect to these
PRUs and also a MDIO port.
The cores can run different firmwares to support different protocols and
features like switch-dev, timestamping, etc.
It uses System DMA to transfer and receive packets and
shared memory register emulation between the firmware and
driver for control and configuration.
This patch adds support for basic EMAC functionality with 1Gbps
and 100Mbps link speed. 10M and half duplex mode are not supported
currently as they require IEP, the support for which will be added later.
Support for switch-dev, timestamp, etc. will be added later
by subsequent patch series.

net: ethernet: dwmac: oxnas glue removal
With [1] removing MPCore SMP support, this makes the OX820 barely usable,
associated with a clear lack of maintainance, development and migration to
dt-schema it's clear that Linux support for OX810 and OX820 should be removed.
In addition, the OX810 hasn't been booted for years and isn't even present
in an ARM config file.
For the OX820, lack of USB and SATA support makes the platform not usable
in the current Linux support and relies on off-tree drivers hacked from the
vendor (defunct for years) sources.
The last users are in the OpenWRT distribution, and today's removal means
support will still be in stable 6.1 LTS kernel until end of 2026.
If someone wants to take over the development even with lack of SMP, I'll
be happy to hand off maintainance.
It has been a fun time adding support for this architecture, but it's time
to get over!

selftests: New selftests for out-of-order-operations patches in mlxsw
In the past, the mlxsw driver made the assumption that the user applies
configuration in a bottom-up manner. Thus netdevices needed to be added to
the bridge before IP addresses were configured on that bridge or SVI added
on top of it, because whatever happened before a netdevice was mlxsw upper
was generally ignored by mlxsw. Recently, several patch series were pushed
to introduce the bookkeeping and replays necessary to offload the full
state, not just the immediate configuration step.
In this patchset, introduce new selftests that directly exercise the out of
order code paths in mlxsw.

This patch series got bigger than I expected. It cleans up the

automotive phy).
Master/slave custom implementation was replaced with the generic
implementation (genphy_c45_config_aneg/genphy_c45_read_status).
The TJA1120 and TJA1103 are a bit different when it comes to the PTP
interface. The timestamp read procedure was changed, some addresses were
changed and some bits were moved from one register to another. Adding
TJA1120 support was tricky, and I tried not to duplicate the code. If
something looks too hacky to you, I am open to suggestions.

Resetting the PCS will break the link and we should reset the PCS on

On TJA1120, the external trigger timestamp now has a VALID bit. This
changes the logic and we can't use the TJA1103 procedure.
For TJA1103, we can always read a valid timestamp from the registers,
compare the new timestamp with the old timestamp and, if they are not the
same, an event occurred. This logic cannot be applied for TJA1120 because
the timestamp is 0 if the VALID bit is not set.

The egress timestamp FIFO/circular buffer work different on TJA1120 than
TJA1103.
For TJA1103 the new timestamp should be manually moved from the FIFO to
the hardware buffer before checking if the timestamp is valid.
For TJA1120 the hardware will move automatically the new timestamp
from the FIFO to the buffer and the user should check the valid bit, read
the timestamp and unlock the buffer by writing any of the buffer
registers(which are read only).
Another change for the TJA1120 is the behaviour of the EGR TS IRQ bit.
This bit was a self-clear bit for TJA1103, but now should be cleared
before reading the timestamp.

In preparation for multi-CPU support, set CPU port LOOKUP MEMBER outside
the port loop and setup the LOOKUP MEMBER mask for user ports only to
the first CPU port.
This is to handle flooding condition where every CPU port is set as
target and prevent packet duplication for unknown frames from user ports.
Secondary CPU port LOOKUP MEMBER mask will be setup later when
port_change_master will be implemented.

Address learning should initially be turned off by the driver for port
operation in standalone mode, then the DSA core handles changes to it
via ds->ops->port_bridge_flags().
Currently this is not the case for qca8k where learning is enabled
unconditionally in qca8k_setup for every user port.
Handle ports configured in standalone mode by making the learning
configurable and not enabling it by default.
Implement .port_pre_bridge_flags and .port_bridge_flags dsa ops to
enable learning for bridge that request it and tweak
.port_stp_state_set to correctly disable learning when port is
configured in standalone mode.

Currently checksum is recalculated and dsa tag stripped even if we later
don't find the dev.
To improve code, exit early if we don't find the dev and skip additional
operation on the skb since it will be freed anyway.
