^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3036) * @sta_notify callback.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3037) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3038) * When the station is asleep, it has three choices: it can wake up,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3039) * it can PS-Poll, or it can possibly start a uAPSD service period.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3040) * Waking up is implemented by simply transmitting all buffered (and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3041) * filtered) frames to the station. This is the easiest case. When
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3042) * the station sends a PS-Poll or a uAPSD trigger frame, mac80211
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3043) * will inform the driver of this with the @allow_buffered_frames
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3044) * callback; this callback is optional. mac80211 will then transmit
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3045) * the frames as usual and set the %IEEE80211_TX_CTL_NO_PS_BUFFER
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3046) * on each frame. The last frame in the service period (or the only
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3047) * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3048) * indicate that it ends the service period; as this frame must have
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3049) * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3050) * When TX status is reported for this frame, the service period is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3051) * marked has having ended and a new one can be started by the peer.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3052) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3053) * Additionally, non-bufferable MMPDUs can also be transmitted by
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3054) * mac80211 with the %IEEE80211_TX_CTL_NO_PS_BUFFER set in them.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3055) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3056) * Another race condition can happen on some devices like iwlwifi
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3057) * when there are frames queued for the station and it wakes up
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3058) * or polls; the frames that are already queued could end up being
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3059) * transmitted first instead, causing reordering and/or wrong
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3060) * processing of the EOSP. The cause is that allowing frames to be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3061) * transmitted to a certain station is out-of-band communication to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3062) * the device. To allow this problem to be solved, the driver can
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3063) * call ieee80211_sta_block_awake() if frames are buffered when it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3064) * is notified that the station went to sleep. When all these frames
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3065) * have been filtered (see above), it must call the function again
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3066) * to indicate that the station is no longer blocked.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3067) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3068) * If the driver buffers frames in the driver for aggregation in any
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3069) * way, it must use the ieee80211_sta_set_buffered() call when it is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3070) * notified of the station going to sleep to inform mac80211 of any
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3071) * TIDs that have frames buffered. Note that when a station wakes up
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3072) * this information is reset (hence the requirement to call it when
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3073) * informed of the station going to sleep). Then, when a service
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3074) * period starts for any reason, @release_buffered_frames is called
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3075) * with the number of frames to be released and which TIDs they are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3076) * to come from. In this case, the driver is responsible for setting
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3077) * the EOSP (for uAPSD) and MORE_DATA bits in the released frames,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3078) * to help the @more_data parameter is passed to tell the driver if
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3079) * there is more data on other TIDs -- the TIDs to release frames
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3080) * from are ignored since mac80211 doesn't know how many frames the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3081) * buffers for those TIDs contain.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3082) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3083) * If the driver also implement GO mode, where absence periods may
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3084) * shorten service periods (or abort PS-Poll responses), it must
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3085) * filter those response frames except in the case of frames that
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3086) * are buffered in the driver -- those must remain buffered to avoid
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3087) * reordering. Because it is possible that no frames are released
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3088) * in this case, the driver must call ieee80211_sta_eosp()
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3089) * to indicate to mac80211 that the service period ended anyway.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3090) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3091) * Finally, if frames from multiple TIDs are released from mac80211
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3092) * but the driver might reorder them, it must clear & set the flags
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3093) * appropriately (only the last frame may have %IEEE80211_TX_STATUS_EOSP)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3094) * and also take care of the EOSP and MORE_DATA bits in the frame.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3095) * The driver may also use ieee80211_sta_eosp() in this case.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3096) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3097) * Note that if the driver ever buffers frames other than QoS-data
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3098) * frames, it must take care to never send a non-QoS-data frame as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3099) * the last frame in a service period, adding a QoS-nulldata frame
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3100) * after a non-QoS-data frame if needed.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3106) * Before HW queue control was introduced, mac80211 only had a single static
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3107) * assignment of per-interface AC software queues to hardware queues. This
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3108) * was problematic for a few reasons:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3109) * 1) off-channel transmissions might get stuck behind other frames
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3110) * 2) multiple virtual interfaces couldn't be handled correctly
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3111) * 3) after-DTIM frames could get stuck behind other frames
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3112) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3113) * To solve this, hardware typically uses multiple different queues for all
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3114) * the different usages, and this needs to be propagated into mac80211 so it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3115) * won't have the same problem with the software queues.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3116) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3117) * Therefore, mac80211 now offers the %IEEE80211_HW_QUEUE_CONTROL capability
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3118) * flag that tells it that the driver implements its own queue control. To do
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3119) * so, the driver will set up the various queues in each &struct ieee80211_vif
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3120) * and the offchannel queue in &struct ieee80211_hw. In response, mac80211 will
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3121) * use those queue IDs in the hw_queue field of &struct ieee80211_tx_info and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3122) * if necessary will queue the frame on the right software queue that mirrors
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3123) * the hardware queue.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3124) * Additionally, the driver has to then use these HW queue IDs for the queue
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3125) * management functions (ieee80211_stop_queue() et al.)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3126) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3127) * The driver is free to set up the queue mappings as needed, multiple virtual
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3128) * interfaces may map to the same hardware queues if needed. The setup has to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3129) * happen during add_interface or change_interface callbacks. For example, a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3130) * driver supporting station+station and station+AP modes might decide to have
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3131) * 10 hardware queues to handle different scenarios:
