Send the is_deferred flag in the availability control TLV so FW
applies a deferred schedule change at the next DW boundary, and report
the NAN_UNI_EVENT_ID_SCHED_UPDATE_DONE and STARTED_CLUSTER events to
mac80211 via ieee80211_nan_sched_update_done() and
ieee80211_nan_cluster_joined().
Both events arrive on the BH-disabled MCU RX path, where notifying
mac80211 inline is wrong: ieee80211_nan_sched_update_done() needs the
wiphy mutex and may sleep, and ieee80211_nan_cluster_joined() would
fire during NAN_START before mac80211 sets sdata->u.nan.started and
before the supplicant subscribes to NL80211_MCGRP_NAN, so the
self-anchor cluster-join is lost and a solo anchor master can never
publish a service.
Deliver both events from a shared nan_deferred_work selected by a
pending bitmap instead. The bitmap spinlock is taken with
spin_lock_bh() on the RX side, the work re-checks nan_vif under the
wiphy mutex, and the stop path clears the bitmap. STARTED_CLUSTER
signals new_cluster=true, and JOINED_CLUSTER is corrected to
new_cluster=false.

Move mt792x interface combination selection into a helper and store the
selected table in mt792x device state.
This keeps the existing non-CNM and CNM combinations unchanged while
making later firmware-gated extensions add combinations without touching
the common wiphy setup path.

The mt792x PCIe DMA setup uses the same standard queue allocation
sequence for data, MCU, firmware download and RX rings.
Factor this part out into a small common helper so later chip support
can reuse the existing flow without duplicating the queue setup logic.
This keeps the common DMA skeleton in one place and makes follow-up
chip-specific DMA changes smaller and easier to review.

Currently, per-radio attributes are set on per-phy basis, i.e., all the
radios present in a wiphy will take attributes values sent from user. But
each radio in a wiphy can get different values from userspace based on
its requirement.
To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM
By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

MediaTek has asked to switch from the ISC license to BSD-3-Clause-Clear,
in order to improve clarity and the legal integrity of the code.
The BSD-3-Clause license includes the "no endorsement" clause, which is
important for protecting the reputation of the original authors and
contributors by preventing unauthorized use of their names for endorsement
purposes.
This clause is absent in the BSD-2-Clause license, which is more permissive
but lacks this specific protection.
This change also cleans up the license of some Kconfig/Makefile files,
which were accidentally marked as GPL.
The GPL 2.0 remains in use on mt76x0, as well as two source files in mt7615
for which the license situation still needs to be clarified.

When the system suspend or resume, the WiFi driver sends
an hif_ctrl command to the firmware and waits for an event.
Due to changes in the event format reported by the chip, the
current mt7925's driver does not account for these changes,
resulting in command timeout. Add flow to handle hif_ctrl
event to avoid command timeout. We also exented API
mt76_connac_mcu_set_hif_suspend for connac3 this time.

We are introducing a new structure, mt792x_link_sta, to manage per-link
configurations in preparation for future station (STA) support of
Multi-Link Operation (MLO).
This patch only includes structural changes and does not involve any
logic changes.
We have moved relevant parameters, such as the wcid from the mt76_wcid
structure, from the mt7921x_sta structure to the mt792x_link_sta structure.
For current drivers that do not support MLO, there is only one link STA,
and link information is accessed via the deflink member.
However, we have not yet created the per-link BSS configuration indexed
by link ID for Multi-Link Device (MLD) support in mt7921x_sta.
This step needs to be completed before adding MLD support for STA mode.
