Revert "staging: wfx: remove unused included header files" This reverts commit 314fd52f01ead9528a5cda5a868425bb736d93a2. It turns .h files into non-stand-alone when building, which might cause problems in the long-run.

wifi: wfx: allow to send frames during ROC Until now, all the traffic was blocked during scan operation. However, scan operation is going to be used to implement Remain On Channel (ROC). In this case, special frames (marked with IEEE80211_TX_CTL_TX_OFFCHAN) must be sent during the operation. These frames need to be sent on the virtual interface #2. Until now, this interface was only used by the device for internal purpose. But since API 3.9, it can be used to send data during scan operation (we hijack the scan process to implement ROC). Thus, we need to change a bit the way we match the frames with the interface. Fortunately, the frames received during the scan are marked with the correct interface number. So there is no change to do on this part.

staging: wfx: replace wfx_tx_queues_get_after_dtim() by wfx_tx_queues_has_cab() It is not necessary to return a skb. Just getting the information if there is traffic to be sent after DTIM is sufficient. In add, the acronym "cab" (Content After (DTIM) Beacon) is used in mac80211 to designate this kind of traffic. So, make wfx_tx_queues_get_after_dtim() return a boolean and rename accordingly.

staging: wfx: correctly retrieve vif ID from Tx confirmation The device is able to send multiple Tx confirmations in the one reply. In this case, there is only one vif identifier for all the confirmations. Unfortunately, to generate this kind of messages the device squashes all the confirmations whatever their vif ID and use the vif ID of the first confirmation. So, the driver cannot rely on the vif ID mentioned in the header. Fortunately, using the packet_id, the driver can retrieve the Tx request and the associated vif.

staging: wfx: repair wfx_flush() Until now, wfx_flush() flushed queue for while device instead of only the queue of the intended vif. It sometime failed with a timeout, but this error was not reported. Moreover, if the device was frozen, wfx_flush didn't do anything and it results a potential warning (and maybe a resource leak) when the frozen device was unregistered. We can also notice that wfx_tx_queues_wait_empty_vif() did only exist to work around the broken feature of wfx_flush(). This patch repair wfx_flush() and therefore drop wfx_tx_queues_wait_empty_vif().
