This is not actually creating a real problem because the path leading to
'val' being used uninitialized will eventually override the full content
of that variable before actually using it for writing the register.
However, the fix is simple and comes at basically no cost.

devlink: linecard and reporters locking cleanup
This patchset does not change functionality.
Patches 1-2 remove linecards lock and reference counting, converting
them to be protected by devlink instance lock as the rest of
the objects.
Patches 3-4 fix the mlx5 auxiliary device devlink locking scheme whis is
needed for proper reporters lock conversion done in the following
patches.
Patches 5-8 remove reporters locks and reference counting, converting
them to be protected by devlink instance lock as the rest of
the objects.
Patches 9 and 10 convert linecards and reporters dumpit callbacks to
recently introduced devlink_nl_instance_iter_dump() infra.
Patch 11 removes no longer needed devlink_dump_for_each_instance_get()
helper.
The last patch adds assertion to devl_is_registered() as dependency on
other locks is removed.

The fact that devlink instance lock is held over mlx5 auxiliary devices
probe and remove routines brought a need to conditionally take devlink
instance lock there. The code is checking a MLX5E_LOCKED_FLOW flag
in mlx5 priv struct.
This is racy and may lead to access devlink objects without holding
instance lock or deadlock.
To avoid this, the only lock-wise sane solution is to make the
devlink entities created by the auxiliary device independent on
the original pci devlink instance. Create devlink instance for the
auxiliary device and put the uplink port instance there alongside with
the port health reporters.

In the am65_cpsw_init_serdes_phy() function, the error handling for the
call to the devm_of_phy_get() function misses the case where the return
value of devm_of_phy_get() is ERR_PTR(-EPROBE_DEFER). Proceeding without
handling this case will result in a crash when the "phy" pointer with
this value is dereferenced by phy_init() in am65_cpsw_enable_phy().
Fix this by adding appropriate error handling code.

This series cleans up the DT/fwnode/ACPI code in the SFP cage driver:
1. Use the newly introduced i2c_get_adapter_by_fwnode(), which removes
the need to know about ACPI handles to find the I2C device.
2. Use device_get_match_data() to get the match data, rather than
having to look up the matching DT device_id to get at the data.
3. Rename gpio_of_names, as this is not DT specific.
4. Remove acpi.h include which is no longer necessary.
5. Remove ctype.h include which, as far as I can tell, was never

These are WiFi 7 devices that will be introduced into the market
in 2023, with new drivers. Wireless extensions haven't been in
real development since 2006. Since wireless has evolved a lot,
and continues to evolve significantly with Multi-Link Operation,
there's really no good way to still support wireless extensions
for devices that do MLO.
Stop supporting wireless extensions for new devices. We don't
consider this a regression since no such devices (apart from

ALU table entry 2 register in KSZ9477 have bit positions reserved for
forwarding port map. This field is referred in ksz9477_fdb_del() for
clearing forward port map and alu table.
But current fdb_del refer ALU table entry 3 register for accessing forward
port map. Update ksz9477_fdb_del() to get forward port map from correct
alu table entry register.
With this bug, issue can be observed while deleting static MAC entries.
Delete any specific MAC entry using "bridge fdb del" command. This should
clear all the specified MAC entries. But it is observed that entries with
self static alone are retained.
Tested on LAN9370 EVB since ksz9477_fdb_del() is used common across

Avoid race between process wakeup and tpacket_v3 block timeout.
The test waits for cfg_timeout_msec for packets to arrive. Packets
arrive in tpacket_v3 rings, which pass packets ("frames") to the
process in batches ("blocks"). The sk waits for req3.tp_retire_blk_tov
msec to release a block.
Set the block timeout lower than the process waiting time, else
the process may find that no block has been released by the time it
scans the socket list. Convert to a ring of more than one, smaller,
blocks with shorter timeouts. Blocks must be page aligned, so >= 64KB.

The referenced commit changed the error code returned by the kernel
when preventing a non-established socket from attaching the ktls
ULP. Before to such a commit, the user-space got ENOTCONN instead
of EINVAL.
The existing self-tests depend on such error code, and the change
caused a failure:
RUN global.non_established ...
tls.c:1673:non_established:Expected errno (22) == ENOTCONN (107)
non_established: Test failed at step #3
FAIL global.non_established
In the unlikely event existing applications do the same, address
the issue by restoring the prior error code in the above scenario.
Note that the only other ULP performing similar checks at init
time - smc_ulp_ops - also fails with ENOTCONN when trying to attach
the ULP to a non-established socket.

The PHY provides only 39b timestamp. With current timing
implementation, we discard lower 7b, leaving 32b timestamp.
The driver reconstructs the full 64b timestamp by correlating the
32b timestamp with cached_time for performance. The reconstruction
algorithm does both forward & backward interpolation.
The 32b timeval has overflow duration of 2^32 counts ~= 4.23 second.
Due to interpolation in both direction, its now ~= 2.125 second
IIRC, going with at least half a duration, the cached_time is updated
with periodic thread of 1 second (worst-case) periodicity.
But the 1 second periodicity is based on System-timer.
With PPB adjustments, if the 1588 timers increments at say
double the rate, (2s in-place of 1s), the Nyquist rate/half duration
sampling/update of cached_time with 1 second periodic thread will
lead to incorrect interpolations.
Hence we should restrict the PPB adjustments to at least half duration
of cached_time update which translates to 500,000,000 PPB.
Since the periodicity of the cached-time system thread can vary,
it is good to have some buffer time and considering practicality of
PPB adjustments, limiting the max_adj to 100,000,000.

Currently the drop action is supported only in switchdev mode.
Add support for offloading receive filters with action drop
in ADQ/non-ADQ modes. This is in addition to other actions
such as forwarding to a VSI (ADQ) or a queue (ADQ/non-ADQ).
Also renamed 'ch_vsi' to 'dest_vsi' as it is valid for multiple
actions such as forward to vsi/queue which may/may not create a
channel vsi.

If the number of Traffic Classes (TC) is decreased, the FW will no
longer remove TC nodes, but will send a pending change notification. This
will allow RDMA to destroy corresponding Control QP markers. After RDMA
finishes outstanding operations, the ice driver will send an execute MIB
Pending change admin queue command to FW to finish DCB configuration
change.
The FW will buffer all incoming Pending changes, so there can be only
one active Pending change.
RDMA driver guarantees to remove Control QP markers within 5000 ms.
Hence, LLDP response timeout txTTL (default 30 sec) will be met.
In the case of a Pending change, LLDP MIB Change Event (opcode 0x0A01) will
contain the whole new MIB. But Get LLDP MIB (opcode 0x0A00) AQ call would
still return an old MIB, as the Pending change hasn't been applied yet.
Add ice_get_dcb_cfg_from_mib_change() function to retrieve DCBX config
from LLDP MIB Change Event's buffer for Pending changes.

In DCB Willing Mode (FW managed LLDP), when the link partner changes
configuration which requires fewer TCs, the TCs that are no longer
needed are suspended by EMP FW, removed, and never resumed. This occurs
before a MIB change event is indicated to SW. The permanent suspension and
removal of these TC nodes in the scheduler prevents RDMA from being able
to destroy QPs associated with this TC, requiring a CORE reset to recover.
A new DCBX configuration change flow is defined to allow SW driver and
other SW components (RDMA) to properly adjust to the configuration
changes before they are taking effect in HW. This flow includes a
two-way handshake between EMP FW<->LAN SW<->RDMA SW.
List of changes:
- Add 'Execute Pending LLDP MIB' AQC.
- Add 'Pending Event Enable' bit.
- Add additional logic to ignore Pending Event Enable' request
while 'LLDP MIB Chnage' event is disabled.
- Add 'Execute Pending LLDP MIB' AQC sending function to FW,
which is needed to take place MIB Event change.

Michael Walle says:
====================
net: phy: Remove probe_capabilities
With all the drivers which used .probe_capabilities converted to the
new c45 MDIO access methods, we can now decide based upon these whether
a bus driver supports c45 and we can get rid of the not widely used
probe_capabilites.
Unfortunately, due to a now broader support of c45 scans, this will
trigger a bug on some boards with a (c22-only) Micrel PHY. These PHYs
don't ignore c45 accesses correctly, thinking they are addressed
themselves and distrupt the MDIO access. To avoid this, a blacklist
for c45 scans is introduced.
