2026-03-24wifi: mt76: add per-link beacon monitoring for MLOFelix Fietkau
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.

2026-03-24wifi: mt76: wait for firmware TX completion of mgmt frames before channel switchFelix Fietkau
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.

2026-03-24wifi: mt76: route nullfunc frames to PSD/ALTX queueFelix Fietkau
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.

2026-03-24wifi: mt76: flush pending TX before channel switchFelix Fietkau
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.

2026-03-24wifi: mt76: send nullfunc PS frames on offchannel transitionsFelix Fietkau
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.

2026-03-24wifi: mt76: optimize ROC for same-channel caseFelix Fietkau
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.

2026-03-24wifi: mt76: abort ROC on chanctx changesFelix Fietkau
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.

2026-03-24wifi: mt76: check chanctx before restoring channel after ROCFelix Fietkau
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. Link: https://patch.msgid.link/20260309060730.87840-4-nbd@nbd.name Signed-off-by: Felix Fietkau <nbd@nbd.name>

Without this check, ROC completion performs a redundant full hardware channel switch when something has already moved the phy back.

2026-03-24wifi: mt76: mt7925: fix incorrect TLV length in CLC commandQuan Zhou
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.

mt76_txq_send_burst does check if the number of non-AQL frames exceeds the maximum. In this case the queue is returned to ieee80211_return_txq when iterating over the scheduled TXQs in mt76_txq_schedule_list. This has the effect of inserting said TXQ at the head of the list. This means the loop will get the same TXQ again, which will terminate the scheduling round. TXQs following in the list thus never get scheduled for transmission. This can manifest in high latency low throughput or broken connections for said STAs. Check if the non-AQL packet count exceeds the limit and not return the TXQ in this case. Schedule all TXQs for the STA in case the non-AQL limit can be satisfied again.

reason Previously, we used the IEEE80211_CONF_IDLE flag to avoid setting the parking channel with the CH_SWITCH_NORMAL reason, which could trigger TX emission before bootup CAC. However, we found that this flag can be set after triggering scanning on a connected station interface, and the reason CH_SWITCH_SCAN_BYPASS_DPD will be used when switching back to the operating channel, which makes the firmware failed to resume paused AC queues. Seems that we should avoid relying on this flag after switching to single multi-radio architecture. Instead, use the existence of chanctx as the condition.

2026-03-24wifi: mt76: avoid to set ACK for MCU command if wait_resp is not setStanleyYP Wang
When wait_resp is not set but the ACK option is enabled in the MCU TXD, the ACK event is enqueued to the MCU event queue without being dequeued by the original MCU command request. Any orphaned ACK events will only be removed from the queue when another MCU command requests a response. Due to sequence index mismatches, these events are discarded one by one until a matching sequence index is found. However, if several MCU commands that do not require a response continue to fill up the event queue, there is a risk that when an MCU command with wait_resp enabled is issued, it may dequeue the wrong event skb, especially if the queue contains events with all possible sequence indices.

2026-03-24wifi: mt76: mt792x: add PSE handling barrier for the large MCU cmdSean Wang
Add a dummy register read in mt76_connac_mcu_rate_txpower_band() to act as a PSE barrier. This would release PSE pages and prevents buffer underflow issues when handling MCU commands with larger payloads without the response in mt76_connac_mcu_set_rate_txpower(). This is a prerequisite patch before enabling MT7902 PCIe and SDIO support.

2026-03-24wifi: mt76: mt7921: handle MT7902 irq_map quirk with mutable copySean Wang
MT7902 PCIe requires a different wm2_complete_mask value, so introduce a mutable per-device copy of the default irq_map and override the field only for this chip. Other devices continue using the shared const template. This is a prerequisite patch before enabling MT7902 PCIe support.

Unify all per-chip conditionals under the new is_connac2() helper. This avoids confusion caused by the previous is_mt7921() check, which implicitly covered multiple connac2 chipsets and no longer reflected its actual scope. This is a clean-up only change with no functional impact.
