Add hardware airtime fairness (ATF) support, using the MAC's weighted
DWRR scheduler (VoW) to balance TX airtime between stations.
This supplements mac80211's software airtime fairness rather than
replacing it: software ATF keeps scheduling the host TX queues, while
the hardware scheduler enforces fairness on the offloaded path where the
host has no airtime accounting, such as when WED is active. It is enabled
by default on mt7916 and newer chipsets; mt7915 is excluded.
A station's TX airtime weight is taken from mac80211 through the
sta_set_airtime_weight op and applied to the hardware scheduler directly;
the per-AC DWRR quantum levels are derived from it on the fly, mapping
the weight logarithmically onto the global hardware quantum table. ATF
and WATF are enabled by default and can be toggled together at runtime
through the "vow_atf" debugfs file.

mt76_register_debugfs_fops() returns the dentry from
debugfs_create_dir(), which yields an error pointer on failure
(notably ERR_PTR(-ENODEV) when CONFIG_DEBUG_FS=n), never NULL. Per
commit ff9fb72bc077 ("debugfs: return error values, not NULL"),
callers do not need to check the return value.
Drop the dead !dir checks in mt7615/mt7915/mt7921/mt7925/mt7996
_init_debugfs(). Converting them to IS_ERR() instead would have
exposed a probe abort on CONFIG_DEBUG_FS=n, since each
*_init_debugfs() caller propagates the helper's return value.
This patch supersedes an earlier proposal that converted the checks
to IS_ERR().

In mt7915_mcu_get_txpower_sku(), the response skb from
mt76_mcu_send_and_get_msg() is used in memcpy without validating
its length:
For TX_POWER_INFO_RATE:
memcpy(res, skb->data + 4, sizeof(res));
where sizeof(res) is MT7915_SKU_RATE_NUM * 2 = 322 bytes.
For TX_POWER_INFO_PATH:
memcpy(txpower, skb->data + 4, len);
In both cases, if the firmware returns a response shorter than
the expected size, the memcpy reads beyond the skb data buffer.
The data surfaces to userspace via debugfs (txpower_sku and
txpower_path).

With HW TX encap offload enabled, the mt76 firmware builds the 802.11
header for the 802.3 frame using the per-WCID context. For a STATION
vif the HDR_TRANS TLV currently sets ToDS=1, which makes the firmware
default to the BSSID as A1 and emit STA->AP-formatted frames
regardless of which peer the WCID points to.
For TDLS-paired peers this is wrong. Data frames go on air addressed
to the AP, the AP MAC-ACKs and silently drops them per IEEE 802.11z
(an AP must not forward to a TDLS-paired peer). Management and
control frames bypass the HW encap path and still reach the peer;
only user data fails.
Add MT_WCID_FLAG_TDLS_PEER, set it in mt7915, mt7921, mt7925 and
mt7996 sta-add paths when sta->tdls is true, and override the
HDR_TRANS TLV in mt76_connac_mcu_wtbl_hdr_trans_tlv() (Connac2 -
mt7915 / mt7921 / mt7922), mt7925_mcu_sta_hdr_trans_tlv() (mt7925)
and mt7996_mcu_sta_hdr_trans_tlv() (mt7996) to set ToDS=0, FromDS=0
when the flag is set. The 3-addr non-DS form matches what 802.11z
uses for direct links; the firmware then constructs the frame with
A1=peer rather than A1=BSSID. HW encap offload remains enabled for
AP and any non-TDLS traffic.
Verified on mt7925e + Samsung S938B over a 5 GHz HE 80 MHz channel
with iperf3 -t 30 to the TDLS peer:
before fix: over the TDLS direct link, 7 TDLS Setup action
frames and 3 RTS frames reach the peer; 0 QoS
Data frames make it through (mgmt/control paths
bypass HW encap, the data path does not). iperf3
stalls.
after fix: 2.90 GBytes transferred at 830 Mbit/s sustained,
0 TCP retransmits.
mt7915, mt7921, mt7922 and mt7996 are not regression-tested in this
change for lack of hardware. Their HDR_TRANS handling mirrors the
verified mt7925 change; the firmware behavior is shared across these

mt76_sta_state() calls the sta_event callback without holding dev->mutex.

The locking pattern in mt76_sta_state() is inconsistent:
- mt76_sta_add() acquires dev->mutex before calling dev->drv->sta_add
- mt76_sta_remove() acquires dev->mutex before calling __mt76_sta_remove

Currently, per-radio attributes are set on per-phy basis, i.e., all the

each radio in a wiphy can get different values from userspace based on
its requirement.
To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT

NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD

NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM
By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

wcid, that is, wcid[9:8] can be overwritten by 0x3 and wcid[7:0] is set
to 0xff by host driver.
However, firmware is unable to get sta_info from DA as DA != RA for
