When a + * station goes to sleep, we will stop transmitting to it. There is, + * however, a race condition: a station might go to sleep while there is + * data buffered on hardware queues. If the device has support for this + * it will reject frames, and the driver should give the frames back to + * mac80211 with the %IEEE80211_TX_STAT_TX_FILTERED flag set which will + * cause mac80211 to retry the frame when the station wakes up. The + * driver is also notified of powersave transitions by calling its + * @sta_notify callback. + * + * When the station is asleep, it has three choices: it can wake up, + * it can PS-Poll, or it can possibly start a uAPSD service period. + * Waking up is implemented by simply transmitting all buffered (and + * filtered) frames to the station. This is the easiest case. When + * the station sends a PS-Poll or a uAPSD trigger frame, mac80211 + * will inform the driver of this with the @allow_buffered_frames + * callback; this callback is optional. mac80211 will then transmit + * the frames as usual and set the %IEEE80211_TX_CTL_POLL_RESPONSE + * on each frame. The last frame in the service period (or the only + * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to + * indicate that it ends the service period; as this frame must have + * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS. + * When TX status is reported for this frame, the service period is + * marked has having ended and a new one can be started by the peer. + * + * Another race condition can happen on some devices like iwlwifi + * when there are frames queued for the station and it wakes up + * or polls; the frames that are already queued could end up being + * transmitted first instead, causing reordering and/or wrong + * processing of the EOSP. The cause is that allowing frames to be + * transmitted to a certain station is out-of-band communication to + * the device. To allow this problem to be solved, the driver can + * call ieee80211_sta_block_awake() if frames are buffered when it + * is notified that the station went to sleep. When all these frames + * have been filtered (see above), it must call the function again + * to indicate that the station is no longer blocked. + * + * If the driver buffers frames in the driver for aggregation in any + * way, it must use the ieee80211_sta_set_buffered() call when it is + * notified of the station going to sleep to inform mac80211 of any + * TIDs that have frames buffered. Note that when a station wakes up + * this information is reset (hence the requirement to call it when + * informed of the station going to sleep). Then, when a service + * period starts for any reason, @release_buffered_frames is called + * with the number of frames to be released and which TIDs they are + * to come from. In this case, the driver is responsible for setting + * the EOSP (for uAPSD) and MORE_DATA bits in the released frames, + * to help the @more_data paramter is passed to tell the driver if + * there is more data on other TIDs -- the TIDs to release frames + * from are ignored since mac80211 doesn't know how many frames the + * buffers for those TIDs contain. + * + * If the driver also implement GO mode, where absence periods may + * shorten service periods (or abort PS-Poll responses), it must + * filter those response frames except in the case of frames that + * are buffered in the driver -- those must remain buffered to avoid + * reordering. Because it is possible that no frames are released + * in this case, the driver must call ieee80211_sta_eosp_irqsafe() + * to indicate to mac80211 that the service period ended anyway. + * + * Finally, if frames from multiple TIDs are released from mac80211 + * but the driver might reorder them, it must clear & set the flags + * appropriately (only the last frame may have %IEEE80211_TX_STATUS_EOSP) + * and also take care of the EOSP and MORE_DATA bits in the frame. + * The driver may also use ieee80211_sta_eosp_irqsafe() in this case. + */ + +/** * enum ieee80211_filter_flags - hardware filter flags * * These flags determine what the filter in hardware should be @@ -1600,6 +1723,17 @@ enum ieee80211_tx_sync_type { }; /** + * enum ieee80211_frame_release_type - frame release reason + * @IEEE80211_FRAME_RELEASE_PSPOLL: frame released for PS-Poll + * @IEEE80211_FRAME_RELEASE_UAPSD: frame(s) released due to + * frame received on trigger-enabled AC + */ +enum ieee80211_frame_release_type { + IEEE80211_FRAME_RELEASE_PSPOLL, + IEEE80211_FRAME_RELEASE_UAPSD, +}; + +/** * struct ieee80211_ops - callbacks from mac80211 to the driver * * This structure contains various callbacks that the driver may @@ -1896,11 +2030,6 @@ enum ieee80211_tx_sync_type { * ieee80211_remain_on_channel_expired().
