WED support requires using non-coherent DMA, whereas the PCI device might
be configured for coherent DMA.
The WED driver will take care of changing the PCI HIF coherent IO setting
on attach.

In rare cases, TRB pointers might be out of sync leads to RMAC stopping
Rx that requires minimal recovery, so add this helper to periodically

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

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

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.

The crash log shown it is possible that mt7921_irq_handler is called while
devm_free_irq is being handled so mt76_free_device need to be postponed
until devm_free_irq is completed to solve the crash we free the mt76 device

This memory allocation failure can be triggered by fault injection or
high pressure testing, resulting a WARN.
Fix this by replacing WARN with pr_warn.

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.
