2026-07-31wifi: mt76: mt792x: stop USB register access after bus hangSean Wang
Mark the mt792x USB bus hung on the first control timeout and switch register access to no-op bus ops. Each failed vendor request may spend up to MT_VEND_REQ_MAX_RETRY * MT_VEND_REQ_TOUT_MS, about 3 seconds, and teardown/reset paths can keep issuing such requests after the device has stopped responding. Also skip the USB WFSYS reset path after bus_hung is set, since it uses UHW vendor requests as well. mt7925u 1-2:1.3: vendor request req:63 off:0018 failed:-110 mt7925u 1-2:1.3: vendor request req:63 off:0018 failed:-110 mt7925u 1-2:1.3: vendor request req:63 off:0018 failed:-110 mt7925u 1-2:1.3: vendor request req:63 off:0018 failed:-110 mt7925u 1-2:1.3: vendor request req:63 off:0018 failed:-110 Avoid repeating those register reads after the bus is known to be hung by switching register access to no-op handlers.

2026-07-31wifi: mt76: mt7925: skip reset work on hung busSean Wang
Skip mt7925 reset handling once the bus is marked hung. A hung bus cannot be recovered by issuing another device reset. Continuing the reset path may only send more failing MCU or register accesses and delay teardown. Return early from reset work and the USB reset path so the failed device can be torn down quickly.

Stop retrying hardware init once the bus is marked hung.

2026-07-31wifi: mt76: mt76x02: report rx FCS errors to mac80211Devin Wittmayer
When the fcsfail filter is enabled the hardware passes frames with a bad FCS up to the driver, but mt76x02_mac_process_rx() never checks MT_RXINFO_CRCERR and hands them to mac80211 without RX_FLAG_FAILED_FCS_CRC. In monitor mode the radiotap flags byte then never gets IEEE80211_RADIOTAP_F_BADFCS set and corrupted frames cannot be told apart from clean ones. Set RX_FLAG_FAILED_FCS_CRC from the descriptor CRC error bit, matching mt7603, mt7615, mt7915, mt7921, mt7925 and mt7996.

2026-07-31wifi: mt76: mt76x02: do not WARN on invalid rx descriptor lengthDevin Wittmayer
The MPDU length in the rx descriptor comes from the hardware. In monitor mode with the fcsfail filter enabled, the hardware passes up corrupted frames, and a corrupted frame can report a length larger than the received buffer. The bounds check correctly discards such frames, but its WARN_ON_ONCE wrapper means any over-the-air garbage frame taints the kernel, and panics it on the first such frame when panic_on_warn is set. Drop the WARN and discard the frame silently, matching what commit c2d4c8723dbf ("mt76x2: remove some harmless WARN_ONs in tx status and rx path") did for the neighboring rx and tx status paths. Observed immediately on rx with an MT7612U in fcsfail monitor mode on a busy channel.

2026-07-31wifi: mt76: mt76u: use a threaded NAPI for the RX pathFilip Bakreski
The USB RX path delivers frames to the stack via mt76_rx_complete() with a NULL napi pointer, taking the netif_receive_skb_list() path, so it never benefits from GRO -- unlike the DMA-based mt76 drivers, which pass a real napi and use napi_gro_receive(). For bulk TCP traffic this is costly, as every segment traverses the stack individually. Service the MT_RXQ_MAIN queue from a threaded NAPI, reusing mt76_dev's existing napi_dev and napi[] rather than adding new fields. The URB completion handler schedules the napi; its poll drains the URBs, builds the skbs, resubmits and delivers them through napi_gro_receive(). The MCU queue stays on the existing RX worker. This enables GRO and moves RX processing into its own kernel thread, parallelising the datapath. On mt7921u at HE-MCS 11 (2x2, 80 MHz; fast.com, multiple streams) this averages ~588 Mbit/s, versus ~424 Mbit/s when the same napi is instead driven manually from the RX worker, and ~380 Mbit/s for the unmodified driver.

2026-07-31wifi: mt76: mt7615: avoid waiting for mac work under the mt76 mutexRunyu Xiao
mt7615_suspend() acquired the mt76 mutex and then called cancel_delayed_work_sync() on mac_work. mt7615_mac_work() acquires the same mutex via mt7615_mutex_acquire() at the top of the worker, so if mac_work is already running and blocked on the mutex, the suspend path deadlocks waiting for the work it holds the mutex against. Flush scan_work and mac_work before taking the mutex, matching the suspend paths in mt7921 and mt7925. scan_work only takes the mt76 spinlock, but moving it keeps the sequence consistent. This also keeps mac_work from running over an already suspended HIF, which the previous split (async cancel under the lock, sync cancel after release) would have allowed.

The MT7991A chipset uses PCI device ID 0x7991 (MT7996_DEVICE_ID_2), but is_mt7996() only checks for 0x7990.

2026-07-31wifi: mm81x: prevent timers from outliving teardownLinmao Li
The three timer teardown paths call timer_delete_sync_try() and ignore its return value. If a callback is running on another CPU it returns -1 without waiting, and it does not prevent a later rearm even when it does deactivate a pending timer. mm81x_skbq_tx_complete() can rearm the stale-status timer, and the rc and yaps callbacks queue work that rearms their timers. Teardown can therefore continue with a callback still running or the timer rearmed, so it fires after the associated state has been freed. Use timer_shutdown_sync() for these permanent teardowns: it waits for an in-flight callback and prevents any future rearm. In mm81x_rc_deinit() shut the timer down before cancel_work_sync() so the work can no longer recreate the timer/work cycle.

2026-07-30net: mctp: usb: Allow multiple urbs in flightJeremy Kerr
Currently, we stop tx queues when we have one urb submitted. This means we will immediately hit dev_hard_start_xmit's tx-queues-off -> NETDEV_TX_BUSY case, and revert to the requeue -> gso_skb single-dequeue path, and no longer be able to pack skbs without an xmit_more indication. Instead, allow a few urbs to be in-flight, with a limit of 16kB of data outstanding (after which we will disable queues). With this, the tx path will cause fewer requeues (and therefore non-packed transfers) under normal loads.

2026-07-30net: mctp: usblib: Implement receive-side packet spanningJeremy Kerr
Using the existing prepare/complete API, we can persist the rx skb across receives to implement v1.1 packet spanning. Alter the packet-extraction loop to allow truncated packets, returning early with the skb persisted for the next IN urb completion. When we see we have a complete packet, netif_rx() that. If the packet boundary aligns with the urb completion, we can netif_rx() the whole thing. Those intermediate packets are cloned from the original (large-transfer-data) skb. Unlike existing behaviour, if the clone fails, we drop just that clone, instead of the existing transfer skb. This allows us to process the rest of the skb data, and any continuation of the span into the next transfer. One subtle change: the mctp_usblib_rx() helper now handles skbs with the full transport header, so we shift the skb_pull() for the header data to the helper, before doing the rx_bytes stats update. We still need to handle non-spanning mode, so error out on truncated-packet cases there.
