net: dsa: microchip: ksz8: Enhance static MAC table operations and error handling
This patch series improves the Microchip ksz8 driver by refactoring
static MAC table operations for code reuse, implementing add/del_fdb
functions, and making better use of error values in
ksz8_r_sta_mac_table() and ksz8_w_sta_mac_table(). The changes aim to
provide a more robust and maintainable driver with improved error
handling.

Announce that the driver supports CAN_CTRLMODE_BERR_REPORTING by means
of priv->can.ctrlmode_supported. Until now berr reporting always has
been active without taking care of the berr-reporting parameter given
to an "ip link set ..." command.
Additionally apply some changes to function esd_usb_rx_event():
- If berr reporting is off and it is also no state change, then
immediately return.
- Unconditionally (even in case of the above "immediate return") store
tx- and rx-error counters, so directly use priv->bec.txerr and
priv->bec.rxerr instead of intermediate variables.
- Not directly related, but to better point out the linkage between a
failed alloc_can_err_skb() and stats->rx_dropped++:

sfc: support unicast PTP
Unicast PTP was not working with sfc NICs.
The reason was that these NICs don't timestamp all incoming packets,
but instead they only timestamp packets of the queues that are selected
for that. Currently, only one RX queue is configured for timestamp: the
RX queue of the PTP channel. The packets that are put in the PTP RX
queue are selected according to firmware filters configured from the
driver.
Multicast PTP was already working because the needed filters are known
in advance, so they're inserted when PTP is enabled. This patches
add the ability to dynamically add filters for unicast addresses,
extracted from the TX PTP-event packets.
Since we don't know in advance how many filters we'll need, some info
about the filters need to be saved. This will allow to check if a filter
already exists or if a filter is too old and should be removed.
Note that the previous point is unnecessary for multicast filters, but
I've opted to change how they're handled to match the new unicast's
filters to avoid having duplicate insert/remove_filters functions,
once for each type of filter.
Tested: With ptp4l, all combinations of IPv4/IPv6, master/slave and
unicast/multicast

When sending a PTP event packet, add the correct filters that will make
that future incoming unicast PTP event packets will be timestamped.
The unicast address for the filter is gotten from the outgoing skb
before sending it.
Until now they were not timestamped because only filters that match with
the PTP multicast addressed were being configured into the NIC for the
PTP special channel. Packets received through different channels are not
timestamped, getting "received SYNC without timestamp" error in ptp4l.
Note that the inserted filters are never removed unless the NIC is stopped
or reconfigured, so efx_ptp_stop is called. Removal of old filters will
be handled by the next patch.
Additionally, cleanup a bit efx_ptp_xmit_skb_mc to use the reverse xmas
tree convention and remove an unnecessary assignment to rc variable in

No filters for unicast are inserted yet. That will be done in the next

The reason to use 2 different lists instead of a single one is that, in

The register-based H2C/C2H are used to exchange information between driver
and firmware, but only apply to narrow area because its data size is
smaller than regular packet-based H2C/C2H.
This kind of H2C/C2H must be paired. To identify if any H2C/C2H is missing,
update counters to help diagnose this kind of problems.

In order to reduce firmware code size cost, remove some counter value from
the structure. But firmware didn't update version code. To parse the
correct report, add another variation version v105 to parse it.

This LPS state will not turn off RF, and it can still do some basic
traffic, only RTL8852B has the state. Coexistence need let Bluetooth
know WiFi is still alive to prevent some Bluetooth performance issue.

net: dsa: add support for MT7988
The MediaTek MT7988 SoC comes with a built-in switch very similar to
previous MT7530 and MT7531. However, the switch address space is mapped
into the SoCs memory space rather than being connected via MDIO.
Using MMIO simplifies register access and also removes the need for a bus
lock, and for that reason also makes interrupt handling more light-weight.
Note that this is different from previous SoCs like MT7621 and MT7623N
which also came with an integrated MT7530-like switch which yet had to be
accessed via MDIO.
Split-off the part of the driver registering an MDIO driver, then add
another module acting as MMIO/platform driver.
The whole series has been tested on various MediaTek boards:
* MT7623A + MT7530 (BPi-R2)
* MT7986A + MT7531 (BPi-R3)
* MT7988A reference board
Changes since v1:
* use 'internal' PHY mode where appropriate
* use regmap_update_bits in mt7530_rmw
* improve dt-bindings
Changes since RFC v3:
* WARN_ON_ONCE if register read fails
* move probing of the reset GPIO and reset controller link out of
common probe function, as they are not actually common
Changes since RFC v2:
* split into many small commits to ease review
* introduce helper functions to reduce code duplication
* use helpers for locking to make lock-skipping easier and less ugly
to implement.
* add dt-bindings for mediatek,mt7988-switch
Changes since initial RFC:
* use regmap for register access and move register access to bus-
specific driver
* move initialization of MT7531 SGMII PCS to MDIO driver

Add driver for the built-in Gigabit Ethernet switch which can be found
in the MediaTek MT7988 SoC.
The switch shares most of its design with MT7530 and MT7531, but has
it's registers mapped into the SoCs register space rather than being
connected externally or internally via MDIO.
Introduce a new platform driver to support that.

As MT7530 and MT7531 internally use 32-bit wide registers, each access
to any register of the switch requires several operations on the MDIO
bus. Hence if there is congruent access, e.g. due to PCS or PHY
polling, this can mess up and interfere with another ongoing register
access sequence.
However, the MDIO bus mutex is only relevant for MDIO-connected
switches. Prepare switches which have there registers directly mapped
into the SoCs register space via MMIO which do not require such
locking. There we can simply use regmap's default locking mechanism.
Hence guard mutex operations to only be performed in case of MDIO
connected switches.

Split MT7530 switch driver into a common part and a part specific
for MDIO connected switches and multi-chip modules.
Move MDIO-specific functions to newly introduced mt7530-mdio.c while
keeping the common parts in mt7530.c.
Introduce new Kconfig symbol CONFIG_NET_DSA_MT7530_MDIO which is
implied by CONFIG_NET_DSA_MT7530.
