Similar to vif link management, postpone sta link destuction in
mt7996_mac_sta_remove() introducing mt7996_mac_sta_remove_link utility
routine and just disable sta link running mt7996_mac_sta_remove_links
routine.
This is a preliminary patch in order to support MLO link reconfiguration
in MT7996 driver.

MT7996 hw requires to remove active links from the mcu BSSINFO table
destroying the interface. For this reason introduce mt7996_vif_link_destroy
routine and remove active (non-offchannel) vif links running
mt7996_remove_interface routine.
This is a preliminary patch in order to support MLO link reconfiguration

Destroy mt76_vif_link struct in mt7996_vif_link_remove routine and not
in mt76_unassign_vif_chanctx(). This is necessary since, in order to
properly support MLO link reconfiguration, we will destroy mt76_vif_link
struct during AP tear-down process and not running unassign_vif_chanctx
mac80211 callback.
This patch does not introduce any regression since
mt76_assign_vif_chanctx/mt76_unassign_vif_chanctx APIs are currently
used just by MT7996 driver.

Rely on msta_link link_id value in mt7996_vif_link_remove routine
instead of using link_conf pointer. This assumption is correct since
msta_link link_id is set to link_conf link_id value in mt7996_vif_link_add
routine.
Moreover, fallback to default ieee80211_bss_conf struct if the link_conf
pointer in mt7996_vif_link_remove() is NULL.
MT7996 hw requires to remove AP MLD links from MCU configuration during
AP tear-down process (e.g. running mt7996_remove_interface()). Doing so,
we can't assume link_conf pointer is always non-NULL running
mt7996_vif_link_remove routine.

With chanctx drivers using hardware scan or remain-on-channel,
mac80211 does not know when the radio goes off-channel, which breaks
its software beacon loss detection.
Implement per-link beacon monitoring in the driver. Track the last
beacon timestamp per link and check for beacon loss periodically from
the mac_work handler.
Beacon monitoring is initialized on association and on late link
activation, and cleared on disassociation. The beacon_mon_last
timestamp is reset when returning from offchannel and after channel
switches to prevent false beacon loss detection.

After flushing software-pending frames to DMA, mt76_has_tx_pending()
only checks DMA ring q->queued. For token-based drivers, q->queued is
decremented at DMA consumption, but firmware may not have transmitted
the frame yet. Waiting for all tokens is not feasible because data
frames may be stuck in firmware powersave/aggregation queues.
Track PSD queue tokens (firmware ALTX) per phy using an atomic counter.
These frames are sent by firmware immediately without PS buffering, so
the counter reliably reaches zero after transmission.
Increment the counter in mt76_token_consume() and decrement it in
mt76_token_release(), only for PSD queue tokens. Include the counter
in mt76_has_tx_pending() so channel switch waits for firmware TX
completion of management and nullfunc frames.
mt7615 (uses mt76_token_get/put) and non-token drivers are unaffected
as they never call mt76_token_consume/release.

ieee80211_is_data() returns true for nullfunc/QoS-nullfunc frames, so
they bypass the PSD queue routing and go through the regular VO data
queue. This means firmware processes them through the normal TID queue
instead of the ALTX queue, which doesn't guarantee immediate
transmission.
Use ieee80211_is_data_present() instead, which returns false for both
management frames and nullfunc/QoS-nullfunc (no payload), routing them
to MT_TXQ_PSD. Firmware maps PSD to the ALTX queue, which transmits
immediately without PS buffering.
This only affects frames from the mt76_tx() pending path. Regular
mac80211 TXQ scheduling is unchanged.

mt76_tx() queues frames on wcid->tx_pending for async processing by
tx_worker. In __mt76_set_channel(), the worker gets disabled before it
may have run, and the subsequent wait only checks DMA ring queues, not
the software pending list. This means frames like nullfunc PS frames
from mt76_offchannel_notify() may never be transmitted on the correct
channel.
Fix this by running mt76_txq_schedule_pending() synchronously after
disabling the tx_worker but before setting MT76_RESET, which would
otherwise cause mt76_txq_schedule_pending_wcid() to bail out.

Since mt76 uses chanctx, mac80211 does not send nullfunc power save
notifications when the driver goes offchannel for scan or ROC.
Add mt76_offchannel_notify() to send nullfunc PM=1 before going
offchannel and PM=0 after returning, so that the AP can buffer
frames during the absence.
For MLO, iterate all vif links on the phy and set
IEEE80211_TX_CTRL_MLO_LINK so that the driver's tx_prepare_skb
resolves the correct per-link wcid.

mt76_remain_on_channel() always creates an HT20 chandef and goes
offchannel, even when the ROC channel matches the operating channel.
This unnecessarily narrows bandwidth and triggers beacon stop/restart.
When the ROC channel matches the current operating channel, preserve
the full chandef and skip the offchannel transition, matching the
optimization already present in the scan code.
Extract the shared same-channel detection into mt76_offchannel_chandef()
and use it in both ROC and scan paths.

mt76_change_chanctx() calls mt76_phy_update_channel() which switches
the hardware channel. If ROC is active on the same phy, this switches
away from the ROC channel and clears offchannel, but leaves ROC state
intact. Mac80211 still thinks the phy is on the ROC channel.
Abort any active ROC before proceeding, matching the pattern already
used in add, remove, assign, unassign, and switch chanctx functions.

mt76_remove_chanctx() sets phy->chanctx to NULL but does not clear
phy->main_chandef. If ROC is later performed on that phy, completion
tries to restore the stale main_chandef channel, programming the
hardware to sit on a channel with no active context.
Add a chanctx check to avoid restoring a channel when no context is
active.

mt76_roc_complete() unconditionally calls __mt76_set_channel() to
restore the operating channel. The scan equivalent mt76_scan_complete()
checks phy->offchannel first, skipping the restore if the phy is
already back on-channel.
Without this check, ROC completion performs a redundant full hardware
channel switch when something has already moved the phy back.

On channels with NO_IR or RADAR flags, wait for beacon before sending
probe requests. Allows active scanning and WPS on restricted channels
if another AP is already present.

The previous implementation of __mt7925_mcu_set_clc() set the TLV length
field (.len) incorrectly during CLC command construction. The length was
initialized as sizeof(req) - 4, regardless of the actual segment length.
This could cause the WiFi firmware to misinterpret the command payload,
resulting in command execution errors.
This patch moves the TLV length assignment to after the segment is
selected, and sets .len to sizeof(req) + seg->len - 4, matching the
actual command content. This ensures the firmware receives the
correct TLV length and parses the command properly.
