In the following patch we need to use ath12k_warn() but don't easily have
access to struct ath12k_base (ab) but do have access to struct ath12k_hw (ah).
So add a new warning helper ath12_hw_warn() which takes the latter but the log
output is still identical but uses the struct device pointer stored to struct
ath12k_hw.

Add changes to add the link vdevs dynamically whenever a channel is assigned
from mac80211 for a link vdev. During vdev create, update ML address of the
vdev to firmware using the new WMI parameter (WMI_TAG_MLO_VDEV_CREATE_PARAMS).
During vdev start, notify the firmware that this link vdev is newly added and
also indicate all its known partners so that the firmware can take necessary
actions to internally update the partners on the new link being added.

In commit 477cabfdb776 ("wifi: ath12k: modify link arvif creation and removal

instead of ret. Switch to use goto to be consistent with the error handling in
the function.

As described in [1], compiling the ath12k driver using clang with
KASAN enabled warns about some functions with excessive stack usage,
with the worst case being:
drivers/net/wireless/ath/ath12k/qmi.c:3546:13: warning: stack frame size (2456) exceeds limit (1024) in 'ath12k_qmi_driver_event_work' [-Wframe-larger-than]
Nathan [2] highlighted work done by Arnd [3] to address similar
issues in other portions of the kernel.
ath12k_qmi_driver_event_work() itself is a pretty lightweight
function, but it dispatches to several other functions which do the
real work:
ath12k_qmi_driver_event_work()
ath12k_qmi_event_server_arrive()
ath12k_qmi_host_cap_send()
ath12k_qmi_event_mem_request()
ath12k_qmi_respond_fw_mem_request()
ath12k_qmi_event_load_bdf()
ath12k_qmi_request_target_cap()
ath12k_qmi_load_bdf_qmi()
ath12k_qmi_wlanfw_m3_info_send()
Mark all of those underlying functions as 'noinline_for_stack' to
prevent them from being inlined in ath12k_qmi_driver_event_work(),
thereby eliminating the excessive stack usage.

During rmmod, the ath11k host driver sends a QMI MODE OFF command
to firmware.
As part of this command, firmware initiates WLAN de-initialization
and accesses certain UMAC registers during this process.
Currently, on WCN6750 WLAN hardware, the system is in a sleep state when
firmware receives the QMI MODE OFF command.
This results in a firmware/hardware reset while accessing the UMAC hardware
registers during sleep state.
To avoid this, add logic to send WCN6750 hardware specific
WMI_PDEV_SUSPEND_AND_DISABLE_INTR command to firmware prior to sending
the QMI MODE OFF command.
This will cause firmware to cease all activities and put the device in
a powered-on state that prevents access to registers which have been
powered off.

====================
wireless-next patches for v6.13
The first -next "new features" pull request for v6.13. This is a big
one as we have not been able to send one earlier. We have also some
patches affecting other subsystems: in staging we deleted the rtl8192e
driver and in debugfs added a new interface to save struct
file_operations memory; both were acked by GregKH.
Because of the lib80211/libipw move there were quite a lot of
conflicts and to solve those we decided to merge net-next into
wireless-next.
Major changes:
cfg80211/mac80211
* stop exporting wext symbols
* new mac80211 op to indicate that a new interface is to be added
* support radio separation of multi-band devices
Wireless Extensions
* move wext spy implementation to libiw
* remove iw_public_data from struct net_device
brcmfmac
* optional LPO clock support
ipw2x00
* move remaining lib80211 code into libiw
wilc1000
* WILC3000 support
rtw89
* RTL8852BE and RTL8852BE-VT BT-coexistence improvements
* tag 'wireless-next-2024-10-25' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (126 commits)
mac80211: Remove NOP call to ieee80211_hw_config

I suggested to put DEBUG_NET_WARN_ON_ONCE() in __sock_create() to
catch possible use-after-free.
But the warning itself was not useful because our interest is in
the callee than the caller.
Let's define DEBUG_NET_WARN_ONCE() and print the name of pf->create()
and the socket identifier.
While at it, we enclose DEBUG_NET_WARN_ON_ONCE() in parentheses too
to avoid a checkpatch error.
Note that %pf or %pF were obsoleted and will be removed later as per
comment in lib/vsprintf.c.

net: phylink: simplify SFP PHY attachment
These two patches simplify how we attach SFP PHYs.
The first patch notices that at the two sites where we call
sfp_select_interface(), if that fails, we always print the same error.
Move this into its own function.
The second patch adds an additional level of validation, checking that
the returned interface is one that is supported by the MAC/PCS.
The last patch simplifies how SFP PHYs are attached, reducing the
number of times that we do validation in this path.

a) The phylink_sfp_connect_phy() and phylink_sfp_config_phy() code
validates the configuration three times:
1. To discover the support/advertising masks that the PHY/PCS/MAC
can support in order to select an interface.
2. To validate the selected interface.
3. When the PHY is brought up after being attached, another validation
is done.
This is needlessly complex.
b) The configuration is set prior to the PHY being attached, which
means we don't have the PHY available in phylink_major_config()
for phylink_pcs_neg_mode() to make decisions upon.
We have already added an extra step to validate the selected interface,
so we can now move the attachment and bringup of the PHY earlier,
inside phylink_sfp_config_phy(). This results in the validation at
step 2 above becoming entirely unnecessary, so remove that too.

Validate that the returned interface from sfp_select_interface() is
supportable by the MAC/PCS. If it isn't, print an error and return
the NA interface type. This is a preparatory step to reorganising
how a PHY on a SFP module is handled.

Whenever we call sfp_select_interface(), we check the returned value
and print an error. There are two cases where this happens with the
same message. Provide a common function to do this.

phylink_parse_fixedlink() wants to preserve the pause, asym_pause and
autoneg bits in pl->supported. Rather than reading the bits into
separate bools, zeroing pl->supported, and then setting them if they
were previously set, use a mask and linkmode_and() to achieve the same
result.

When the ring size changes successfully, trigger
netdev_update_features() to enable features in wanted state if
applicable.
An example of such scenario:
$ ip link set dev eth1 up
$ ethtool --set-ring eth1 rx 8192
$ ip link set dev eth1 mtu 9000
$ ethtool --features eth1 rx-gro-hw on --> fails
$ ethtool --set-ring eth1 rx 1024
With this patch, HW GRO will be turned on automatically because
it is set in the device's wanted_features.

Both gcc-14 and clang-18 report that passing a non-string literal as the
format argument of dev_set_name() is potentially insecure.
E.g. clang-18 says:
drivers/net/wwan/wwan_core.c:442:34: warning: format string is not a string literal (potentially insecure) [-Wformat-security]
442 | return dev_set_name(&port->dev, buf);
| ^~~
drivers/net/wwan/wwan_core.c:442:34: note: treat the string as an argument to avoid this
442 | return dev_set_name(&port->dev, buf);
| ^
| "%s",
It is always the case where the contents of mod is safe to pass as the
format argument. That is, in my understanding, it never contains any
format escape sequences.
But, it seems better to be safe than sorry. And, as a bonus, compiler
output becomes less verbose by addressing this issue as suggested by
clang-18.
Compile tested only.
No functional change intended.

ipv4: Prepare core ipv4 files to future .flowi4_tos conversion.
Continue preparing users of ->flowi4_tos (struct flowi4) to the future
conversion of this field (from __u8 to dscp_t). The objective is to
have type annotation to properly separate DSCP bits from ECN ones. This
way we'll ensure that ECN doesn't interfere with DSCP and avoid
regressions where it break routing descisions (fib rules in particular).
This series concentrates on some easy IPv4 conversions where
->flowi4_tos is set directly from an IPv4 header, so we can get the
DSCP value using the ip4h_dscp() helper function.

Use ip4h_dscp() to get the DSCP from the IPv4 header, then convert the
dscp_t value to __u8 with inet_dscp_to_dsfield().
Then, when we'll convert .flowi4_tos to dscp_t, we'll just have to drop

On this Cisco MX60W, u-boot sets the local-mac-address property.
Unfortunately by default, the MAC is wrong and is actually located on a
UBI partition. Which means nvmem needs to be used to grab it.
In the case where that fails, EMAC fails to initialize instead of
generating a random MAC as many other drivers do.
Match behavior with other drivers to have a working ethernet interface.
