Add support for the independent control state machine per IEEE
802.1AX-2008 5.4.15 in addition to the existing implementation of the
coupled control state machine.
Introduces two new states, AD_MUX_COLLECTING and AD_MUX_DISTRIBUTING in
the LACP MUX state machine for separated handling of an initial
Collecting state before the Collecting and Distributing state. This
enables a port to be in a state where it can receive incoming packets
while not still distributing. This is useful for reducing packet loss when
a port begins distributing before its partner is able to collect.
Added new functions such as bond_set_slave_tx_disabled_flags and
bond_set_slave_rx_enabled_flags to precisely manage the port's collecting
and distributing states. Previously, there was no dedicated method to
disable TX while keeping RX enabled, which this patch addresses.
Note that the regular flow process in the kernel's bonding driver remains
unaffected by this patch. The extension requires explicit opt-in by the
user (in order to ensure no disruptions for existing setups) via netlink
support using the new bonding parameter coupled_control. The default value
for coupled_control is set to 1 so as to preserve existing behaviour.

net: ravb: Prepare for suspend to RAM and runtime PM support (part 1)
This series prepares ravb driver for runtime PM support and adjust the
already existing suspend to RAM code to work for RZ/G3S (R9A08G045) SoC.
As there are IP versions that switch to module standby when disabling
the clocks, and because of module standby IP switches to reset and
the register content is lost, to be able to have runtime PM supported
for all IP variants, the configuration operations were moved all to
ravb_open()/ravb_close() letting the ravb_probe() and ravb_remove()
to deal with resource parsing and allocation/free.
The ethtool and IOCTL APIs that could have been run asyncronously
were adapted to return if the interface is down. As explained in
each individual commits description, this should be harmless.
Along with it, the series contains preparatory cleanups.
The series has been tested on the boards with the following device trees:
- r8a7742-iwg21d-q7.dts
- r8a774a1-hihope-rzg2m-ex.dts
- r9a07g043u11-smarc-rzg2ul.dts

The runtime PM implementation will disable clocks at the end of
ravb_probe(). As some IP variants switch to reset mode as a result of
setting module standby through clock disable APIs, to implement runtime PM
the resource parsing and requesting are moved in the probe function and IP
settings are moved in the open function. This is done because at the end of
the probe some IP variants will switch anyway to reset mode and the
registers content is lost. Also keeping only register settings operations
in the ravb_open()/ravb_close() functions will make them faster.
Commit moves IRQ requests to ravb_probe() to have all the IRQs ready when
the interface is open. As now getting/requesting IRQs is done in a single
place there is no need to keep intermediary data (like ravb_rx_irqs[] and
ravb_tx_irqs[] arrays or IRQs in struct ravb_private).
In order to avoid accessing the IP registers while the IP is runtime
suspended (e.g. in the timeframe b/w the probe requests shared IRQs and
IP clocks are enabled) in the interrupt handlers were introduced
pm_runtime_active() checks. The device runtime PM usage counter has been
incremented to avoid disabling the device's clocks while the check is in
progress (if any).
This is a preparatory change to add runtime PM support for all IP variants.

Reference clock could be or not be part of the power domain. If it is part
of the power domain, the power domain takes care of properly setting it. In
case it is not part of the power domain and full runtime PM support is
available in driver the clock will not be propertly disabled/enabled at
runtime. For this, keep the prepare/unprepare operations in the driver's
probe()/remove() functions and move the enable/disable in runtime PM
functions.
By doing this, the previous ravb_runtime_nop() function was renamed
ravb_runtime_suspend() and the comment was removed. A proper runtime PM
resume function was added (ravb_runtime_resume()). The current driver
still don't need to make any register settings on runtime suspend/resume

pm_runtime_put_sync() is called on the driver remove function. This will be
changed in the next commits (that extends the runtime PM support) such
that proper register settings (along with runtime resume/suspend) will be
done on ravb_open()/ravb_close().
Along with it, the other clock request operations were moved close to
reference clock request and prepare to have all the clock requests

CONFIG_PM. The RZ/V2M Ethernet DT node has proper power-domain binding
available in device tree from the commit that added the Ethernet node.
(4872ca1f92b0 ("arm64: dts: renesas: r9a09g011: Add ethernet nodes")).
Power domain support was available in the rzg2l-cpg.c driver when the
Ethernet DT node has been enabled in RZ/V2M device tree.
(ef3c613ccd68 ("clk: renesas: Add CPG core wrapper for RZ/G2L SoC")).
Thus, remove the explicit clock enable for gptp_clk (and treat it as the
other clocks are treated) as it is not needed and removing it doesn't
break the ABI according to the above explanations.
By removing the enable/disable operation from the driver we can add

Fixups for qca8k ds->user_mii_bus cleanup
The series "ds->user_mii_bus cleanup (part 1)" from the last development
cycle:
https://patchwork.kernel.org/project/netdevbpf/cover/20240104140037.374166-1-vladimir.oltean@nxp.com/
had some review comments I didn't have the time to address at the time.
One from Alvin and one from Luiz. They can reasonably be treated as
improvements for v6.9.

It was pointed out during the review [1] of commit 68e1010cda79 ("net:
dsa: qca8k: put MDIO bus OF node on qca8k_mdio_register() failure") that
the rest of the qca8k driver uses "int ret" rather than "int err".
Make everything consistent in that regard, not only
qca8k_mdio_register(), but also qca8k_setup_mdio_bus().

It was pointed out during the review [1] of commit e66bf63a7f67 ("net:
dsa: qca8k: skip MDIO bus creation if its OF node has status =
"disabled"") that we now leak a reference to the "mdio" OF node if it is
disabled.
This is only a concern when using dynamic OF as far as I can tell (like
probing on an overlay), since OF nodes are never freed in the regular
case. Additionally, I'm unaware of any actual device trees (in
production or elsewhere) which have status = "disabled" for the MDIO OF
node. So handling this as a simple enhancement.

====================
mptcp: annotate lockless access
This is a series of 5 patches from Paolo to annotate lockless access.
The MPTCP locking schema is already quite complex. We need to clarify it
and make the lockless access already there consistent, or later changes
will be even harder to follow and understand.
This series goes through all the msk fields accessed in the RX and TX
path and makes the lockless annotation consistent with the in-use
locking schema.
As a bonus, this should fix data races eventually found by fuzzers --
even if we haven't seen many such reports so far.
Patch 1/5 hints we could remove "local_key" and "remote_key" from the
subflow context, and always use the ones from the msk socket, possibly
reducing the context memory usage. That change is left over as a
possible follow-up.

The following MPTCP socket fields:
- can_ack
- fully_established
- rcv_data_fin
- snd_data_fin_enable
- rcv_fastclose
- use_64bit_ack
are accessed without any lock, add the appropriate annotation.
The schema is safe as each field can change its value at most
once in the whole mptcp socket life cycle.
