When a firmware watchdog triggers full SER recovery before any VAPs
are up, mac80211 skips drv_reconfig_complete() because open_count is
zero. This leaves the DRIVER queue stop reason set permanently,
blocking all TX when interfaces eventually start.

The net_setup_tc callback is chosen at compile time and the WED
handler shadows the NPU one when CONFIG_NET_MEDIATEK_SOC_WED is
enabled. mt76_wed_net_setup_tc() returns -EOPNOTSUPP without an
active WED device, so on boards using the Airoha NPU with a WED
enabled kernel the tc offload block is never bound and PPE flow
offload for wireless traffic is silently disabled.
Dispatch on the active offload backend instead: use the WED handler
when a WED device is attached and fall back to the NPU handler
otherwise. Builds without MT76_NPU keep the old behavior through the
mt76_npu_net_setup_tc() stub.

The MLO link-reconfiguration rework moved the per-phy num_sta
decrement inside a link_valid guard. link_valid is only set for
MLO links, but num_sta is incremented for every station link,
including the non-MLO deflink. Non-MLO stations bump num_sta
on association and never drop it on removal.
A non-zero num_sta forces connected-mode off-channel scanning which
prevents the directed probe exchange needed to find hidden APs.
Decrement phy->num_sta on the actual link teardown, pairing it with
the unconditional increment on link creation.

A non-MLD station's EAPOL and data frames are tagged with link_id ==
IEEE80211_LINK_UNSPECIFIED, which now skips the per-link lookup in
mt7996_mac_write_txwi() and leaves omac_idx/band_idx/wmm_idx at slot
0. When the radio also runs AP VAPs the station's omac is non-zero
(get_omac_idx() prefers HW BSSID slots 1-3), so its EAPOL frames
egress from the wrong BSS and the 4-way handshake times out even
though association succeeds.
In mt7996_tx_prepare_skb(), resolve the link from the peer wcid when
link_id is UNSPECIFIED and the wcid is not the global entry, restoring
the pre-MLO behaviour for station traffic.

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.

mt76_remain_on_channel() and mt76_roc_complete() call mt76_set_channel()
while already holding dev->mutex. Since mt76_set_channel() also acquires
dev->mutex, this results in a deadlock.
Use __mt76_set_channel() instead of mt76_set_channel().
Add cancel_delayed_work_sync() for mac_work before acquiring the mutex
in mt76_remain_on_channel() to prevent a secondary deadlock with the
mac_work workqueue.
