When two split-phy devices that support overlapping frequency ranges within
the same band(say 5 GHz low and 5 GHz high) are grouped into an ath12k
hardware (HW) setup, they share a common wiphy instance. Consequently, the
channel list (wiphy->bands[]) becomes unified across all associated
radios (ar).
When a scan is triggered with frequency list containing frequencies of
both 5 GHz low and 5 GHz high, mac80211 generates a single scan request
to driver with all the frequencies. This is because mac80211 splits the
scan request based on band.
ath12k checks the first frequency in the requested scan frequency list and
initiates scan to corresponding radio's(ar) firmware with all the
frequencies. Firmware rejects this scan since some of the frequencies in
the scan request are not supported, resulting in a scan failure.
To fix this ath12k driver should split the scan request into multiple
scans based on requested frequencies and schedule them to corresponding
underlying radio(s) in parallel.
Currently, ath12k driver assigns the scan link (link 15) in ahvif->links[]
for scan vdev creation. However, with parallel scan support being
introduced in the following patch, multiple radios (e.g., 5 GHz low and
5 GHz high) in the same HW group may attempt to use the same scan link
concurrently, causing conflicts where the vdev created by one radio could
be deleted and re-initialized by another.
To address this, reserve space for additional scan links for each radio in
a MLO group and allow subsequent radios to use different available scan
links (ahvif->link[15..MAX_SCAN_LINKS]) when scan link (15) is
pre-occupied.
While at it, rename ATH12K_DEFAULT_SCAN_LINK as ATH12K_FIRST_SCAN_LINK
as there is no longer only one scan link.

In MLO configuration, ath12k_mac_radio_start() iterates through all
the radios and makes the ar state 'ON'. Even though some bands are
not supported in certain countries, ath12k_reg_update_chan_list()
tries to update the channel list for all the active pdevs and ends
up in the warn_on for non-supported band.
To prevent this, disable the pdev when the number of channels across
all bands supported by the pdev is zero for a particular country.

During beacon miss handling, ath12k driver iterates over active virtual
interfaces (vifs) and attempts to access the radio object (ar) via
arvif->deflink->ar.
However, after commit aa80f12f3b ("wifi: ath12k: defer vdev creation for
MLO"), arvif is linked to a radio only after vdev creation, typically when
a channel is assigned or a scan is requested.
For P2P capable devices, a default P2P interface is created by
wpa_supplicant along with regular station interfaces, these serve as dummy
interfaces for P2P-capable stations, lack an associated netdev and initiate
frequent scans to discover neighbor p2p devices. When a scan is initiated
on such P2P vifs, driver selects destination radio (ar) based on scan
frequency, creates a scan vdev, and attaches arvif to the radio. Once the
scan completes or is aborted, the scan vdev is deleted, detaching arvif
from the radio and leaving arvif->ar uninitialized.
While handling beacon miss for station interfaces, P2P interface is also
encountered in the vif iteration and ath12k_mac_handle_beacon_miss_iter()
tries to dereference the uninitialized arvif->deflink->ar.
Fix this by verifying that vdev is created for the arvif before accessing
its ar during beacon miss handling and similar vif iterator callbacks.

In the case of SME-in-driver, the driver can internally choose to
update the links based on the AP MLD recommendation and do link
reconfiguration negotiation with AP MLD.
(e.g., After the driver processing the BSS Transition Management request
frame received from the AP MLD with Neighbor Report containing
Multi-Link element with recommended links information chooses to do link
reconfiguration negotiation with AP MLD).
To support this, extend cfg80211_mlo_reconf_add_done() and
NL80211_CMD_ASSOC_MLO_RECONF to indicate added links information for
driver-initiated link reconfiguration requests. For removed links,
the driver indicates links information using the
NL80211_CMD_LINKS_REMOVED event for driver-initiated cases, the same as
supplicant initiated cases.
For the driver-initiated case, cfg80211 will receive link
reconfiguration result asynchronously from driver so holding BSSes of
the accepted add links is needed in the event path. Also, no need of
unhold call for the rejected add link BSSes since there was no hold call
happened previously.
Once the supplicant receives the NL80211_CMD_ASSOC_MLO_RECONF event,
it needs to process the information about newly added links and install
per-link group keys (e.g., GTK/IGTK/BIGTK etc.).
In case of the SME-in-driver, using a vendor interface etc. to notify
the supplicant to initiate a link reconfiguration request and then
supplicant sending command to the cfg80211 can lead to race conditions.
The correct design to avoid this is that the driver indicates the
cfg80211 directly with the results of the link reconfiguration
negotiation.

channel, -EBUSY is returned even when a scan is requested on a different

In multi-radio wiphy cases, multiple radios are grouped under a single

requested on a different radio of the same wiphy, the scan can be allowed

no longer makes sense (if it ever did), attr set may differ message
by messsage. Isolate the part of decoding responsible for attr-set
specific interpretation and call it once we identified the correct op.
Without this fix performing SET operation on an ethtool socket, while
being subscribed to notifications causes:
# File "tools/net/ynl/pyynl/lib/ynl.py", line 1096, in _op
# Exception| return self._ops(ops)[0]
# Exception| ~~~~~~~~~^^^^^
# File "tools/net/ynl/pyynl/lib/ynl.py", line 1040, in _ops
# Exception| nms = NlMsgs(reply, attr_space=op.attr_set)
# Exception| ^^^^^^^^^^^
The value of op we use on line 1040 is stale, it comes form the previous
loop. If a notification comes before a response we will update op to None
and the next iteration thru the loop will break with the trace above.

Setting tty->disc_data before opening the NCI device means we need to
clean it up on error paths. This also opens some short window if device
starts sending data, even before NCIUARTSETDRIVER IOCTL succeeded
(broken hardware?). Close the window by exposing tty->disc_data only on
the success path, when opening of the NCI device and try_module_get()

The code differs in error path in one aspect: tty->disc_data won't be

However, lan743x_ptp_io_event_clock_get() writes to ptp->extts[] with

Support bandwidth clamping in mana using net shapers
This patchset introduces hardware-backed bandwidth rate limiting
for MANA NICs via the net_shaper_ops interface, enabling efficient and
fine-grained traffic shaping directly on the device.
Previously, MANA lacked a mechanism for user-configurable bandwidth
control. With this addition, users can now configure shaping parameters,
allowing better traffic management and performance isolation.
The implementation includes the net_shaper_ops callbacks in the MANA
driver and supports one shaper per vport. Add shaping support via
mana_set_bw_clamp(), allowing the configuration of bandwidth rates
in 100 Mbps increments (minimum 100 Mbps). The driver validates input
and rejects unsupported values. On failure, it restores the previous
configuration which is queried using mana_query_link_cfg() or
retains the current state.
To prevent potential deadlocks introduced by net_shaper_ops, switch to
_locked variants of NAPI APIs when netdevops_lock is held during
VF setup and teardown.
Also, Add support for ethtool get_link_ksettings to report the maximum
link speed supported by the SKU in mbps.
These APIs when invoked on hardware that are older or that do
not support these APIs, the speed would be reported as UNKNOWN and
the net-shaper calls to set speed would fail.

Introduce support for net_shaper_ops in the MANA driver,
enabling configuration of rate limiting on the MANA NIC.
To apply rate limiting, the driver issues a HWC command via
mana_set_bw_clamp() and updates the corresponding shaper object
in the net_shaper cache. If an error occurs during this process,
the driver restores the previous speed by querying the current link
configuration using mana_query_link_cfg().
The minimum supported bandwidth is 100 Mbps, and only values that are
exact multiples of 100 Mbps are allowed. Any other values are rejected.
To remove a shaper, the driver resets the bandwidth to the maximum
supported by the SKU using mana_set_bw_clamp() and clears the
associated cache entry. If an error occurs during this process,
the shaper details are retained.
On the hardware that does not support these APIs, the net-shaper
calls to set speed would fail.
Set the speed:

Add support for PSE budget evaluation strategy
This series brings support for budget evaluation strategy in the PSE
subsystem. PSE controllers can set priorities to decide which ports should
be turned off in case of special events like over-current.
This patch series adds support for two budget evaluation strategy.
1. Static Method:
This method involves distributing power based on PD classification.
It’s straightforward and stable, the PSE core keeping track of the
budget and subtracting the power requested by each PD’s class.
Advantages: Every PD gets its promised power at any time, which
guarantees reliability.
Disadvantages: PD classification steps are large, meaning devices
request much more power than they actually need. As a result, the power
supply may only operate at, say, 50% capacity, which is inefficient and
wastes money.
2. Dynamic Method:
To address the inefficiencies of the static method, vendors like
Microchip have introduced dynamic power budgeting, as seen in the
PD692x0 firmware. This method monitors the current consumption per port
and subtracts it from the available power budget. When the budget is
exceeded, lower-priority ports are shut down.
Advantages: This method optimizes resource utilization, saving costs.
Disadvantages: Low-priority devices may experience instability.
The UAPI allows adding support for software port priority mode managed from
userspace later if needed.
Patches 1-2: Add support for interrupt event report in PSE core, ethtool
and ethtool specs.
Patch 3: Adds support for interrupt and event report in TPS23881 driver.
Patches 4,5: Add support for PSE power domain in PSE core and ethtool.
Patches 6-8: Add support for budget evaluation strategy in PSE core,
ethtool and ethtool specs.
Patches 9-11: Add support for port priority and power supplies in PD692x0
drivers.
Patches 12,13: Add support for port priority in TPS23881 drivers.

Interrupt support is essential for the proper functioning of the TPS23881
