fcfe1b5e16 mt76: fix tx status related use-after-free race on station removal
There is a small race window where ongoing tx activity can lead to a skb
getting added to the status tracking idr after that idr has already been
cleaned up, which will keep the wcid linked in the status poll list.
Fix this by only adding status skbs if the wcid pointer is still assigned
in dev->wcid, which gets cleared early by mt76_sta_pre_rcu_remove

bc98e7fdd8 mt76: fix encap offload ethernet type check
The driver needs to check if the format is 802.2 vs 802.3 in order to set
a tx descriptor flag. skb->protocol can't be used, since it may not be properly
initialized for packets coming in from a packet socket.
Fix misdetection by checking the ethertype from the skb data instead

46f6adbfce mt76: mt7915: disable RX_HDR_TRANS_SHORT
This patch disables RX_TRANS_SHORT to make MDP to do header translation
when payload less than 8 bytes, hence the (QoS) null data can be encapsulated
to 802.3 format. However, WDS requires (QoS) null data in 802.11 format
to created vlan AP interfaces.

2c33360bce wfx: use container_of() to get vif
Currently, upon virtual interface creation, wfx_add_interface() stores
a reference to the corresponding struct ieee80211_vif in private data,
for later usage. This is not needed when using the container_of
construct. This construct already has all the info it needs to retrieve
the reference to the corresponding struct from the offset that is
already available, inherent in container_of(), between its type and
member inputs (struct ieee80211_vif and drv_priv, respectively).
Remove vif (which was previously storing the reference to the struct
ieee80211_vif) from the struct wfx_vif, define a function
wvif_to_vif(wvif) for container_of(), and replace all wvif->vif with
the newly defined container_of construct.

'vmm_table' array contains the size of data buffer length including host
header length. In 'vmm_table' array, the Zero value means the end of
vmm_entries that needs to transfer to firmware which is calculated based on
VMM free size in firmware.

Use 'vmm_table' valid entry check before fetching the entry from TX queue to
only copy valid number of entries to avoid possible NULL pointer exception
observed sometimes during large file transfers.
