In that case, it will be told about the desired powersave mode - * with the %IEEE80211_CONF_PS flag depending on the association status. - * The hardware must take care of sending nullfunc frames when necessary, - * i.e. when entering and leaving powersave mode. The hardware is required - * to look at the AID in beacons and signal to the AP that it woke up when - * it finds traffic directed to it. - * - * %IEEE80211_CONF_PS flag enabled means that the powersave mode defined in - * IEEE 802.11-2007 section 11.2 is enabled. This is not to be confused - * with hardware wakeup and sleep states. Driver is responsible for waking - * up the hardware before issuing commands to the hardware and putting it - * back to sleep at appropriate times. - * - * When PS is enabled, hardware needs to wakeup for beacons and receive the - * buffered multicast/broadcast frames after the beacon. Also it must be - * possible to send frames and receive the acknowledment frame. - * - * Other hardware designs cannot send nullfunc frames by themselves and also - * need software support for parsing the TIM bitmap. This is also supported - * by mac80211 by combining the %IEEE80211_HW_SUPPORTS_PS and - * %IEEE80211_HW_PS_NULLFUNC_STACK flags. The hardware is of course still - * required to pass up beacons. The hardware is still required to handle - * waking up for multicast traffic; if it cannot the driver must handle that - * as best as it can, mac80211 is too slow to do that. - * - * Dynamic powersave is an extension to normal powersave in which the - * hardware stays awake for a user-specified period of time after sending a - * frame so that reply frames need not be buffered and therefore delayed to - * the next wakeup. It's compromise of getting good enough latency when - * there's data traffic and still saving significantly power in idle - * periods. - * - * Dynamic powersave is simply supported by mac80211 enabling and disabling - * PS based on traffic. Driver needs to only set %IEEE80211_HW_SUPPORTS_PS - * flag and mac80211 will handle everything automatically. Additionally, - * hardware having support for the dynamic PS feature may set the - * %IEEE80211_HW_SUPPORTS_DYNAMIC_PS flag to indicate that it can support - * dynamic PS mode itself. The driver needs to look at the - * @dynamic_ps_timeout hardware configuration value and use it that value - * whenever %IEEE80211_CONF_PS is set. In this case mac80211 will disable - * dynamic PS feature in stack and will just keep %IEEE80211_CONF_PS - * enabled whenever user has enabled powersave. - * - * Some hardware need to toggle a single shared antenna between WLAN and - * Bluetooth to facilitate co-existence. These types of hardware set - * limitations on the use of host controlled dynamic powersave whenever there - * is simultaneous WLAN and Bluetooth traffic. For these types of hardware, the - * driver may request temporarily going into full power save, in order to - * enable toggling the antenna between BT and WLAN. If the driver requests - * disabling dynamic powersave, the @dynamic_ps_timeout value will be - * temporarily set to zero until the driver re-enables dynamic powersave. - * - * Driver informs U-APSD client support by enabling - * %IEEE80211_HW_SUPPORTS_UAPSD flag. The mode is configured through the - * uapsd paramater in conf_tx() operation. Hardware needs to send the QoS - * Nullfunc frames and stay awake until the service period has ended. To - * utilize U-APSD, dynamic powersave is disabled for voip AC and all frames - * from that AC are transmitted with powersave enabled. - * - * Note: U-APSD client mode is not yet supported with - * %IEEE80211_HW_PS_NULLFUNC_STACK. - */ - -/** - * DOC: Beacon filter support - * - * Some hardware have beacon filter support to reduce host cpu wakeups - * which will reduce system power consumption.

This can consist in notifying the host when - * the RSSI changes significantly or when it drops below or rises above - * configurable thresholds. In the future these thresholds will also be - * configured by mac80211 (which gets them from userspace) to implement - * them as the roaming algorithm requires. - * - * If the hardware cannot implement this, the driver should ask it to - * periodically pass beacon frames to the host so that software can do the - * signal strength threshold checking. - */ - -/** - * DOC: Spatial multiplexing power save - * - * SMPS (Spatial multiplexing power save) is a mechanism to conserve - * power in an 802.11n implementation.

However, for best CPU usage and power consumption, - * having as few frames as possible percolate through the stack is - * desirable. Hence, the hardware should filter as much as possible. - * - * To achieve this, mac80211 uses filter flags (see below) to tell - * the driver's configure_filter() function which frames should be - * passed to mac80211 and which should be filtered out. - * - * Before configure_filter() is invoked, the prepare_multicast() - * callback is invoked with the parameters @mc_count and @mc_list - * for the combined multicast address list of all virtual interfaces. - * It's use is optional, and it returns a u64 that is passed to - * configure_filter(). Additionally, configure_filter() has the - * arguments @changed_flags telling which flags were changed and - * @total_flags with the new flag states. - * - * If your device has no multicast address filters your driver will - * need to check both the %FIF_ALLMULTI flag and the @mc_count - * parameter to see whether multicast frames should be accepted - * or dropped. - * - * All unsupported flags in @total_flags must be cleared. - * Hardware does not support a flag if it is incapable of _passing_ - * the frame to the stack. Otherwise the driver must ignore - * the flag, but not clear it. - * You must _only_ clear the flag (announce no support for the - * flag to mac80211) if you are not able to pass the packet type - * to the stack (so the hardware always filters it). - * So for example, you should clear @FIF_CONTROL, if your hardware - * always filters control frames. If your hardware always passes - * control frames to the kernel and is incapable of filtering them, - * you do _not_ clear the @FIF_CONTROL flag. - * This rule applies to all other FIF flags as well. - */ - -/** - * DOC: AP support for powersaving clients - * - * In order to implement AP and P2P GO modes, mac80211 has support for - * client powersaving, both "legacy" PS (PS-Poll/null data) and uAPSD. - * There currently is no support for sAPSD. - * - * There is one assumption that mac80211 makes, namely that a client - * will not poll with PS-Poll and trigger with uAPSD at the same time. - * Both are supported, and both can be used by the same client, but - * they can't be used concurrently by the same client. This simplifies - * the driver code. - * - * The first thing to keep in mind is that there is a flag for complete - * driver implementation: %IEEE80211_HW_AP_LINK_PS. If this flag is set, - * mac80211 expects the driver to handle most of the state machine for - * powersaving clients and will ignore the PM bit in incoming frames. - * Drivers then use ieee80211_sta_ps_transition() to inform mac80211 of - * stations' powersave transitions. In this mode, mac80211 also doesn't - * handle PS-Poll/uAPSD. - * - * In the mode without %IEEE80211_HW_AP_LINK_PS, mac80211 will check the - * PM bit in incoming frames for client powersave transitions. 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 - * programmed to let through and what should not be passed to the - * stack.

If you added any work onto the mac80211 workqueue - * you should ensure to cancel it on this callback. - * Must be implemented and can sleep. - * - * @suspend: Suspend the device; mac80211 itself will quiesce before and - * stop transmitting and doing any other configuration, and then - * ask the device to suspend.

In the case where the driver buffers some frames for - * sleeping stations mac80211 will use this callback to tell the driver - * to release some frames, either for PS-poll or uAPSD. - * Note that if the @more_data paramter is %false the driver must check - * if there are more frames on the given TIDs, and if there are more than - * the frames being released then it must still set the more-data bit in - * the frame. If the @more_data parameter is %true, then of course the - * more-data bit must always be set. - * The @tids parameter tells the driver which TIDs to release frames - * from, for PS-poll it will always have only a single bit set. - * In the case this is used for a PS-poll initiated release, the - * @num_frames parameter will always be 1 so code can be shared. In - * this case the driver must also set %IEEE80211_TX_STATUS_EOSP flag - * on the TX status (and must report TX status) so that the PS-poll - * period is properly ended. This is used to avoid sending multiple - * responses for a retried PS-poll frame. - * In the case this is used for uAPSD, the @num_frames parameter may be - * bigger than one, but the driver may send fewer frames (it must send - * at least one, however). In this case it is also responsible for - * setting the EOSP flag in the QoS header of the frames. Also, when the - * service period ends, the driver must set %IEEE80211_TX_STATUS_EOSP - * on the last frame in the SP. Alternatively, it may call the function - * ieee80211_sta_eosp_irqsafe() to inform mac80211 of the end of the SP. - * This callback must be atomic. - * @allow_buffered_frames: Prepare device to allow the given number of frames - * to go out to the given station. The frames will be sent by mac80211 - * via the usual TX path after this call. The TX information for frames - * released will also have the %IEEE80211_TX_CTL_POLL_RESPONSE flag set - * and the last one will also have %IEEE80211_TX_STATUS_EOSP set. In case - * frames from multiple TIDs are released and the driver might reorder - * them between the TIDs, it must set the %IEEE80211_TX_STATUS_EOSP flag - * on the last frame and clear it on all others and also handle the EOSP - * bit in the QoS header correctly. Alternatively, it can also call the - * ieee80211_sta_eosp_irqsafe() function. - * The @tids parameter is a bitmap and tells the driver which TIDs the - * frames will be on; it will at most have two bits set. - * This callback must be atomic. - */ -struct ieee80211_ops { - void (*tx)(struct ieee80211_hw *hw, struct sk_buff *skb);
