/**
+ * DOC: HW queue control
+ *
+ * Before HW queue control was introduced, mac80211 only had a single static
+ * assignment of per-interface AC software queues to hardware queues. This
+ * was problematic for a few reasons:
+ * 1) off-channel transmissions might get stuck behind other frames
+ * 2) multiple virtual interfaces couldn't be handled correctly
+ * 3) after-DTIM frames could get stuck behind other frames
+ *
+ * To solve this, hardware typically uses multiple different queues for all
+ * the different usages, and this needs to be propagated into mac80211 so it
+ * won't have the same problem with the software queues.
+ *
+ * Therefore, mac80211 now offers the %IEEE80211_HW_QUEUE_CONTROL capability
+ * flag that tells it that the driver implements its own queue control. To do
+ * so, the driver will set up the various queues in each &struct ieee80211_vif
+ * and the offchannel queue in &struct ieee80211_hw. In response, mac80211 will
+ * use those queue IDs in the hw_queue field of &struct ieee80211_tx_info and
+ * if necessary will queue the frame on the right software queue that mirrors
+ * the hardware queue.
+ * Additionally, the driver has to then use these HW queue IDs for the queue
+ * management functions (ieee80211_stop_queue() et al.)
+ *
+ * The driver is free to set up the queue mappings as needed, multiple virtual
+ * interfaces may map to the same hardware queues if needed. The setup has to
+ * happen during add_interface or change_interface callbacks. For example, a
+ * driver supporting station+station and station+AP modes might decide to have
+ * 10 hardware queues to handle different scenarios:
+ *
+ * 4 AC HW queues for 1st vif: 0, 1, 2, 3
+ * 4 AC HW queues for 2nd vif: 4, 5, 6, 7
+ * after-DTIM queue for AP: 8
+ * off-channel queue: 9
+ *
+ * It would then set up the hardware like this:
+ * hw.offchannel_tx_hw_queue = 9
+ *
+ * and the first virtual interface that is added as follows:
+ * vif.hw_queue[IEEE80211_AC_VO] = 0
+ * vif.hw_queue[IEEE80211_AC_VI] = 1
+ * vif.hw_queue[IEEE80211_AC_BE] = 2
+ * vif.hw_queue[IEEE80211_AC_BK] = 3
+ * vif.cab_queue = 8 // if AP mode, otherwise %IEEE80211_INVAL_HW_QUEUE
+ * and the second virtual interface with 4-7.
+ *
+ * If queue 6 gets full, for example, mac80211 would only stop the second
+ * virtual interface's BE queue since virtual interface queues are per AC.
+ *
+ * Note that the vif.cab_queue value should be set to %IEEE80211_INVAL_HW_QUEUE
+ * whenever the queue is not used (i.e. the interface is not in AP mode) if the
+ * queue could potentially be shared since mac80211 will look at cab_queue when
+ * a queue is stopped/woken even if the interface is not in AP mode.
