++/**
++ * 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.
