b514c47ebf net: stmmac: set PP_FLAG_DMA_SYNC_DEV only if XDP is enabled
Commit 5fabb01207 ("net: stmmac: Add initial XDP support") sets
PP_FLAG_DMA_SYNC_DEV flag for page_pool unconditionally,
page_pool_recycle_direct() will call page_pool_dma_sync_for_device()
on every page even the page is not going to be reused by XDP program.

When XDP is not enabled, the page which holds the received buffer
will be recycled once the buffer is copied into new SKB by
skb_copy_to_linear_data(), then the MAC core will never reuse this
page any longer. Always setting PP_FLAG_DMA_SYNC_DEV wastes CPU cycles
on unnecessary calling of page_pool_dma_sync_for_device().

After this patch, up to 9% noticeable performance improvement was observed
on certain platforms.

7d627137dc net/mlx5: Support throttled commands from async API
Currently, commands that qualify as throttled can't be used via the
async API. That's due to the fact that the throttle semaphore can sleep
but the async API can't.

This patch allows throttling in the async API by using the tentative
variant of the semaphore and upon failure (semaphore at 0) returns EBUSY
to signal to the caller that they need to wait for the completion of
previously issued commands.

Furthermore, make sure that the semaphore is released in the callback.

675faf5a14 net: stmmac: Fix zero-division error when disabling tc cbs
The commit b8c43360f6 ("net: stmmac: No need to calculate speed divider
when offload is disabled") allows the "port_transmit_rate_kbps" to be
set to a value of 0, which is then passed to the "div_s64" function when
tc-cbs is disabled. This leads to a zero-division error.

When tc-cbs is disabled, the idleslope, sendslope, and credit values the
credit values are not required to be configured. Therefore, adding a return
statement after setting the txQ mode to DCB when tc-cbs is disabled would
prevent a zero-division error.

4e2c9cd7dc Merge tag 'i2c-for-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
 "I2C core:

   - finally remove the I2C_COMPAT symbol after 15 years of deprecation

   - lock client addresses during initialization to prevent race
     conditions between different kinds of instantiation

   - use scoped foreach OF child loops

   - testunit cleanups and documentation improvements, as well as two
     new tests, one for repeated start and one for triggering SMBusAlert
     interrupts

  I2C host drivers:

   - DesignWare and Renesas I2C driver updates.

     The first has has undergone through a series of cleanups that have
     been sent to the mailing list a year ago for the first time and
     finally get merged in this pull request. They are many, from typos
     (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline
     functions to librarieas) and many others.

   - all the DesignWare Kconfig options have been grouped under the
     I2C_DESIGNWARE_CORE and this required some adaptation in many of
     the kernel configuration files for different arm and mips boards

  Cleanups:

   - improve the exit path in the runtime resume function for the
     Qualcomm Geni platform

   - get rid of the unused "target_addr" parameter in the Intel LJCA
     driver

   - intialize the restart_flag in the MediaTek controller in one single
     place

   - constify a few global data structures in the virtio driver

   - simplify the bus speed handling in the Renesas driver init function
     making it more readable

   - improved probe function of the Renesas R-Car driver

   - switch the iMX/MXC driver to use RUNTIME_PM_OPS() instead of
     SET_RUNTIME_PM_OPS()

   - iMX/MXC driver cleanups

   - use devm_clk_get_enabled() to simplify the Renesas EMEV2, Ingenic
     and MPC drivers

  Refactoring:

   - Fix a potential out of boundary array access in the Nuvoton driver.

     This is not a bug fix because the issue could never occur due to
     hardware not having the properties listed in the array. The change
     makes the driver more future proof and, at the same time, silences
     code analyzers.

  Improvements:

   - several patches improving the runtime power management handling of
     the Renesas I2C (riic) driver

   - use a more descriptive adapter name in the Intel i801 driver to
     show the presence of the IDF feature

   - kill pending transactions when irq's can't complete their handling
     in the Intel Denverton (ismt) driver, triggering a timeout

  New Feature:

   - support fast mode plus in the Renesas I2C (riic) driver

  New support:

   - Added support for:
      - Renesas R9A08G045
      - Rockchip RK3576
      - KEBA I2C
      - Theobroma Systems Mule Multiplexer.

   - new i2c-keba.c driver

   - new driver for The Mule i2c multiplexer

  Core I2C framework:

   - move runtime PM functions in order to allow them to be accessed
     during device add

  Devicetree:

   - nVidia and Qualcomm binding improvements

   - get rid of redundant "multi-master" property in the aspeed binding

   - convert i2c-sprd binding to YAML

  AT24 updates:

  - document a new model from giantec in DT bindings"

b5109b60ee net: seeq: Fix use after free vulnerability in ether3 Driver Due to Race Condition
In the ether3_probe function, a timer is initialized with a callback
function ether3_ledoff, bound to &prev(dev)->timer. Once the timer is
started, there is a risk of a race condition if the module or device
is removed, triggering the ether3_remove function to perform cleanup.
The sequence of operations that may lead to a UAF bug is as follows:

CPU0                                    CPU1

                      |  ether3_ledoff
ether3_remove         |
  free_netdev(dev);   |
  put_devic           |
  kfree(dev);         |
 |  ether3_outw(priv(dev)->regs.config2 |= CFG2_CTRLO, REG_CONFIG2);
                      | // use dev

Fix it by ensuring that the timer is canceled before proceeding with
the cleanup in ether3_remove.

5a6caa2cfa net: xilinx: axienet: Fix packet counting
axienet_free_tx_chain returns the number of DMA descriptors it's
handled. However, axienet_tx_poll treats the return as the number of
packets. When scatter-gather SKBs are enabled, a single packet may use
multiple DMA descriptors, which causes incorrect packet counts. Fix this
by explicitly keepting track of the number of packets processed as
separate from the DMA descriptors.

Budget does not affect the number of Tx completions we can process for
NAPI, so we use the ring size as the limit instead of budget. As we no
longer return the number of descriptors processed to axienet_tx_poll, we
now update tx_bd_ci in axienet_free_tx_chain.

Pull timer updates from Thomas Gleixner:
 "Core:

   - Overhaul of posix-timers in preparation of removing the workaround
     for periodic timers which have signal delivery ignored.

   - Remove the historical extra jiffie in msleep()

     msleep() adds an extra jiffie to the timeout value to ensure
     minimal sleep time. The timer wheel ensures minimal sleep time
     since the large rewrite to a non-cascading wheel, but the extra
     jiffie in msleep() remained unnoticed. Remove it.

   - Make the timer slack handling correct for realtime tasks.

     The procfs interface is inconsistent and does neither reflect
     reality nor conforms to the man page. Show the correct 0 slack for
     real time tasks and enforce it at the core level instead of having
     inconsistent individual checks in various timer setup functions.

   - The usual set of updates and enhancements all over the place.

  Drivers:

   - Allow the ACPI PM timer to be turned off during suspend

   - No new drivers

   - The usual updates and enhancements in various drivers"

Pull thermal control updates from Rafael Wysocki:
 "These mostly continue to rework the thermal core and the thermal zone
  driver interface to make the code more straightforward and reduce
  bloat

  The most significant piece of this work is a change of the code
  related to binding cooling devices to thermal zones which, among other
  things, replaces two previously existing thermal zone operations with
  one allowing driver implementations to be much simpler

  There is also a new thermal core testing module allowing mock thermal
  zones to be created and controlled via debugfs in order to exercise
  the thermal core functionality. It is expected to be used for
  implementing thermal core self tests in the future

  Apart from the above, there are assorted thermal driver updates

  Specifics:

   - Update some thermal drivers to eliminate thermal_zone_get_trip()
     calls from them and get rid of that function (Rafael Wysocki)

   - Update the thermal sysfs code to store trip point attributes in
     trip descriptors and get to trip points via attribute pointers
     (Rafael Wysocki)

   - Move the computation of the low and high boundaries for
     thermal_zone_set_trips() to __thermal_zone_device_update() (Daniel
     Lezcano)

   - Introduce a debugfs-based facility for thermal core testing (Rafael
     Wysocki)

   - Replace the thermal zone .bind() and .unbind() callbacks for
     binding cooling devices to thermal zones with one .should_bind()
     callback used for deciding whether or not a given cooling devices
     should be bound to a given trip point in a given thermal zone
     (Rafael Wysocki)

   - Eliminate code that has no more users after the other changes, drop
     some redundant checks from the thermal core and clean it up (Rafael
     Wysocki)

   - Fix rounding of delay jiffies in the thermal core (Rafael Wysocki)

   - Refuse to accept trip point temperature or hysteresis that would
     lead to an invalid threshold value when setting them via sysfs
     (Rafael Wysocki)

   - Adjust states of all uninitialized instances in the .manage()
     callback of the Bang-bang thermal governor (Rafael Wysocki)

   - Drop a couple of redundant checks along with the code depending on
     them from the thermal core (Rafael Wysocki)

   - Rearrange the thermal core to avoid redundant checks and simplify
     control flow in a couple of code paths (Rafael Wysocki)

   - Add power domain DT bindings for new Amlogic SoCs (Georges Stark)

   - Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() in the ST
     driver and add a Kconfig dependency on THERMAL_OF subsystem for the
     STi driver (Raphael Gallais-Pou)

   - Simplify the error code path in the probe functions in the brcmstb
     driver with the helo of dev_err_probe() (Yan Zhen)

   - Make imx_sc_thermal use dev_err_probe() (Alexander Stein)

   - Remove trailing space after \n newline in the Renesas driver (Colin
     Ian King)

   - Add DT binding compatible string for the SA8255p to the tsens
     thermal driver (Nikunj Kela)

   - Use the devm_clk_get_enabled() helpers to simplify the init routine
     in the sprd thermal driver (Huan Yang)

   - Remove __maybe_unused notations for the functions by using the new
     RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros on the IMx and
     Qoriq drivers (Fabio Estevam)

   - Remove unused declarations from the ti-soc-thermal driver's header
     file as the functions in question were removed previously (Zhang
     Zekun)"

56375086d0 net: ti: icssg-prueth: Enable HSR Tx duplication, Tx Tag and Rx Tag offload
The HSR stack allows to offload its Tx packet duplication functionality to
the hardware. Enable this offloading feature for ICSSG driver. Add support
to offload HSR Tx Tag Insertion and Rx Tag Removal and duplicate discard.

hsr tag insertion offload and hsr dup offload are tightly coupled in
firmware implementation. Both these features need to be enabled / disabled
together.

Duplicate discard is done as part of RX tag removal and it is
done by the firmware. When driver sends the r30 command
ICSSG_EMAC_HSR_RX_OFFLOAD_ENABLE, firmware does RX tag removal as well as
duplicate discard.

9c699a8f3b net: enetc: Replace ifdef with IS_ENABLED
The enetc driver uses ifdefs when checking whether
CONFIG_FSL_ENETC_PTP_CLOCK is enabled in a number of places. This works
if the driver is built-in but fails if the driver is available as a
kernel module. Replace the instances of ifdef with use of the IS_ENABLED
macro, that will evaluate as true when this feature is built as a kernel
module and follows the kernel's coding style.

9f3e7f11f2 fbnic: Set napi irq value after calling netif_napi_add
The driver calls netif_napi_set_irq() and then calls netif_napi_add(),
which calls netif_napi_add_weight(). At the end of
netif_napi_add_weight() is a call to netif_napi_set_irq(napi, -1), which
clears the previously set napi->irq value. Fix this by calling
netif_napi_set_irq() after calling netif_napi_add().

This was found when reviewing another patch and I have no way to test
this, but the fix seemed relatively straight forward.

b9c7ac4fe2 r8169: disable ALDPS per default for RTL8125
En-Wei reported that traffic breaks if cable is unplugged for more
than 3s and then re-plugged. This was supposed to be fixed by
621735f590 ("r8169: fix rare issue with broken rx after link-down on
RTL8125"). But apparently this didn't fix the issue for everybody.
The 3s threshold rang a bell, as this is the delay after which ALDPS
kicks in. And indeed disabling ALDPS fixes the issue for this user.
Maybe this fixes the issue in general. In a follow-up step we could
remove the first fix attempt and see whether anybody complains.

7fd551a87b net: ag71xx: remove dead code path
The "err" is always zero, so the following branch can never be executed:
if (err) {
	ndev->stats.rx_dropped++;
	kfree_skb(skb);
}
Therefore, the "if" statement can be removed.

Use "ndev->stats.rx_errors" to count "napi_build_skb()" failure

b7468c0fe1 net: ethernet: ti: am65-cpsw: setup priority to flow mapping
Now that we support multiple RX queues, enable default priority
to flow mapping so that higher priority packets come on higher
channels (flows).

The Classifier checks for PCP/DSCP priority in the packet and
routes them to the appropriate flow.
