Jacob Keller says:
====================
ice: Introduce ETH56G PHY model for E825C products
E825C products have a different PHY model than E822, E823 and E810 products.
This PHY is ETH56G and its support is necessary to have functional PTP stack
for E825C products.
This series refactors the ice driver to add support for the new PHY model.
Karol introduces the ice_ptp_hw structure. This is used to replace some
hard-coded values relating to the PHY quad and port numbers, as well as to
hold the phy_model type.
Jacob refactors the driver code that converts between the ice_ptp_tmr_cmd
enumeration and hardware register values to better re-use logic and reduce
duplication when introducing another PHY type.
Sergey introduces functions to help enable and disable the Tx timestamp
interrupts. This makes the ice_ptp.c code more generic and encapsulates the
PHY specifics into ice_ptp_hw.c
Karol introduces helper functions to clear the valid bits for Tx and Rx
timestamps. This enables informing hardware to discard stale timestamps
after performing clock operations.
Sergey moves the Clock Generation Unit (CGU) logic out of the E822 specific
area of the ice_ptp_hw.c file as it will be re-used for other device PHY
models.
Jacob introduces a helper function for obtaining the base increment values,
moving this logic out of ice_ptp.c and into the ice_ptp_hw.c file to better
encapsulate hardware differences.
Sergey builds on these refactors to introduce the new ETH56G PHY model used
by the E825C products. This includes introducing the required helpers,
constants, and PHY model checks.
Karol simplifies the CGU logic by using anonymous structures, dropping an
unnecessary ".field" name for accessing the CGU data.
Michal Michalik updates the CGU logic to support the E825C hardware,
ensuring that the clock generation is configured properly.
Grzegorz Nitka adds support to read the NAC topology data from the device.
This is in preparation for supporting devices which combine two NACs
together, connecting all ports to the same clock source. This enables the
driver to determine if its operating on such a device, or if its operating
on the standard 1-NAC configuration.
Grzsecgorz Nitka adjusts the PTP initialization to prepare for the 2x50G
E825C devices, introducing special mapping for the PHY ports to prepare for
support of the 2-NAC devices.
With this, the ice driver is capable of handling PTP for the single-NAC
E825C devices. Complete support for the 2-NAC devices requirs some work on
how the ports connect to the clock owner. During review of this work, it
was pointed out that our existing use of auxiliary bus is disliked, and
Jiri requested that we change it. We are currently working on developing a
replacement solution for the auxiliary bus implementation and have dropped
the relevant changes out of this series. A future series will refactor the
port to clock connection, at which time we will finish the support for
2-NAC E825C devices.

>From FW/HW perspective, 2 port topology in E825C devices requires
merging of 2 port mapping internally and breakout mapping externally.
As a consequence, it requires different port numbering from PTP code
perspective.
For that topology, pf_id can not be used to index PTP ports. Even if
the 2nd port is identified as port with pf_id = 1, all PHY operations
need to be performed as it was port 2. Thus, special mapping is needed
for the 2nd port.
This change adds detection of 2x50G topology and applies 'custom'
mapping on the 2nd port.

Multiple places in the driver code need to convert enum ice_ptp_tmr_cmd
values into register bits for both the main timer and the PHY port
timers. The main MAC register has one bit scheme for timer commands,
while the PHY commands use a different scheme.
The E810 and E830 devices use the same scheme for port commands as used
for the main timer. However, E822 and ETH56G hardware has a separate
scheme used by the PHY.
Introduce helper functions to convert the timer command enumeration into
the register values, reducing some code duplication, and making it
easier to later refactor the individual port write commands.

When releasing a socket in ax25_release(), we call netdev_put() to
decrease the refcount on the associated ax.25 device. However, the
execution path for accepting an incoming connection never calls
netdev_hold(). This imbalance leads to refcount errors, and ultimately
to kernel crashes.
A typical call trace for the above situation will start with one of the
following errors:
refcount_t: decrement hit 0; leaking memory.
refcount_t: underflow; use-after-free.
And will then have a trace like:

On reboot (or any attempt to remove the interface), the kernel gets

This patch corrects these issues by ensuring that we call netdev_hold()
and ax25_dev_hold() for new connections in ax25_accept(). This makes the
logic leading to ax25_accept() match the logic for ax25_bind(): in both
cases we increment the refcount, which is ultimately decremented in
ax25_release().

changed to DIM_APPLY_NEW_PROFILE;
2. dim is disabled or parameters have not been modified;
3. virtnet_rx_dim_work exits directly;
Then, even if net_dim is invoked again, it cannot work because the

The Motorcomm PHY driver is now maintained by the OEM. The driver has

to test against the new portions of it. Therefore I am removing myself as

In the cpuset_css_online(), clearing the CS_SCHED_LOAD_BALANCE bit
of cs->flags is guarded by callback_lock and cpuset_mutex. There is
no problem with itself, because it is consistent with the description
of there two global lock at the beginning of this file. However, since
the operation of checking, setting and clearing the flag bit is atomic,
protection of callback_lock is unnecessary here, see CS_SPREAD_*. so
to make it more consistent with the other code, move the operation
outside the critical section of callback_lock.
No functional changes intended.

Here is a single revert for a much-reported regression in 6.10-rc1 when
it comes to a few older architectures. Turns out that the VT ioctls
don't work the same across all cpu types because of some old
compatibility requrements for stuff like alpha and powerpc. So revert
the change that attempted to have them use the _IO() macros and go back
to the known-working values instead.
This has NOT been in linux-next but has had many reports that it fixes
the issue with 6.10-rc1.

Since commit 0a44dfc070 ("wifi: mac80211: simplify non-chanctx
drivers") ieee80211_hw_config() is no longer called with changed = ~0.
rtlwifi relied on ~0 in order to ignore the default retry limits of
4/7, preferring 48/48 in station mode and 7/7 in AP/IBSS.
RTL8192DU has a lot of packet loss with the default limits from
mac80211. Fix it by ignoring IEEE80211_CONF_CHANGE_RETRY_LIMITS
completely, because it's the simplest solution.
