mt7925_mcu_config_sniffer() hardcodes drop_err = 1, ignoring what
mac80211 actually requested via configure_filter(). FIF_FCSFAIL is
computed there but discarded instead of persisted.
Persist the FCSFAIL bit on the phy in mt7925_configure_filter() and
read it back in mt7925_mcu_config_sniffer() to derive drop_err, so the
firmware sniffer only passes through unfiltered/marginal frames when a
monitor listener actually requested them.
mt7925_mcu_config_sniffer() is only reached from mt7925_change_chanctx(),
which is itself only exercised on a monitor-mode chanctx, so this stays
scoped to monitor mode.

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.

MT7927 needs DBDC enabled and uses a fixed firmware band assignment for
2.4GHz and 5/6GHz BSS contexts.
Reprogram the STA dev context when the channel context is assigned so the
firmware sees the updated band_idx before the BSS is used. This avoids
stale band programming after band changes.

Add the MT7927-specific PCIe DMA queue layout and local DMA setup,
including the extra RX ring and WFDMA/prefetch programming.
MT7927 does not follow the mt7925 DMA configuration, so provide a
separate DMA init path while reusing the existing common queue setup.
This keeps the chip-specific changes local and prepares the driver
for later MT7927 enablement without affecting existing devices.

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

When enter suspend/resume while in a connected state, the upper layer
will trigger disconnection before entering suspend, and at the same time,
it will trigger regd_notifier() and update CLC, causing the CLC event to
not be received due to suspend, resulting in a command timeout.
Therefore, the update of CLC is postponed until resume, to ensure data
consistency and avoid the occurrence of command timeout.

Filogic 360, which can support Station, AP, P2P, and monitor modes.
Filogic 360 supports max 4096-QAM/160MHz radio operation at 6 GHz, 5 GHz,
or 2.4 GHz with 2x2 antennas. This chip supports PCIe and USB bus type.
mt7925 supports Wi-Fi 6E and EHT rate with single link only at this moment,
whereas Wi-Fi 7 and its specific features are working in progress. They will be
introduced in further patches.
The driver is build tested by Intel's kernel test robot with both GCC and Clang
with several architecture. Sparse reports no warnings.
There are multiple authors, they are listed in alphabetical order below.
