|
||||||
|
+ * DOC: mac80211 software tx queueing
|
||||||
|
+ *
|
||||||
|
+ * mac80211 provides an optional intermediate queueing implementation designed
|
||||||
|
+ * to allow the driver to keep hardware queues short and provide some fairness
|
||||||
|
+ * between different stations/interfaces.
|
||||||
|
+ * In this model, the driver pulls data frames from the mac80211 queue instead
|
||||||
|
+ * of letting mac80211 push them via drv_tx().
|
||||||
|
+ * Other frames (e.g. control or management) are still pushed using drv_tx().
|
||||||
|
+ *
|
||||||
|
+ * Intermediate queues (struct ieee80211_txq) are kept per-sta per-tid, with a
|
||||||
|
+ * single per-vif queue for multicast data frames.
|
||||||
|
+ *
|
||||||
|
+ * The driver is expected to initialize its private per-queue data for stations
|
||||||
|
+ * and interfaces in the .add_interface and .sta_add ops.
|
||||||
|
+ *
|
||||||
|
+ * The driver can not access the queue directly. To dequeue a frame, it calls
|
||||||
|
+ * ieee80211_tx_dequeue(). Whenever mac80211 adds a new frame to a queue, it
|
||||||
|
+ * calls the .wake_tx_queue driver op.
|
||||||
|
+ *
|
||||||
|
+ * For AP powersave TIM handling, the driver only needs to indicate if it has
|
||||||
|
+ * buffered packets in the driver specific data structures by calling
|
||||||
|
+ * ieee80211_sta_set_buffered(). For frames buffered in the ieee80211_txq
|
||||||
|
+ * struct, mac80211 sets TIM and calls .release_buffered_frames().
|
||||||
|
+ * The driver is expected to release its own buffered frames and also call
|
||||||
|
+ * ieee80211_tx_dequeue() within that callback.
