*
+ * @suspend: Suspend the device; mac80211 itself will quiesce before and
+ * stop transmitting and doing any other configuration, and then
+ * ask the device to suspend. This is only invoked when WoWLAN is
+ * configured, otherwise the device is deconfigured completely and
+ * reconfigured at resume time.
+ * The driver may also impose special conditions under which it
+ * wants to use the "normal" suspend (deconfigure), say if it only
+ * supports WoWLAN when the device is associated. In this case, it
+ * must return 1 from this function.
+ *
+ * @resume: If WoWLAN was configured, this indicates that mac80211 is
+ * now resuming its operation, after this the device must be fully
+ * functional again. If this returns an error, the only way out is
+ * to also unregister the device. If it returns 1, then mac80211
+ * will also go through the regular complete restart on resume.
+ *
* @add_interface: Called when a netdevice attached to the hardware is
* enabled. Because it is not called for monitor mode devices, @start
* and @stop must be implemented.
* which set IEEE80211_KEY_FLAG_TKIP_REQ_RX_P1_KEY.
* The callback must be atomic.
*
+ * @set_rekey_data: If the device supports GTK rekeying, for example while the
+ * host is suspended, it can assign this callback to retrieve the data
+ * necessary to do GTK rekeying, this is the KEK, KCK and replay counter.
+ * After rekeying was done it should (for example during resume) notify
+ * userspace of the new replay counter using ieee80211_gtk_rekey_notify().
+ *
* @hw_scan: Ask the hardware to service the scan request, no need to start
* the scan state machine in stack. The scan must honour the channel
* configuration done by the regulatory agent in the wiphy's
* any error unless this callback returned a negative error code.
* The callback can sleep.
*
+ * @cancel_hw_scan: Ask the low-level tp cancel the active hw scan.
+ * The driver should ask the hardware to cancel the scan (if possible),
+ * but the scan will be completed only after the driver will call
+ * ieee80211_scan_completed().
+ * This callback is needed for wowlan, to prevent enqueueing a new
+ * scan_work after the low-level driver was already suspended.
+ * The callback can sleep.
+ *
+ * @sched_scan_start: Ask the hardware to start scanning repeatedly at
+ * specific intervals. The driver must call the
+ * ieee80211_sched_scan_results() function whenever it finds results.
+ * This process will continue until sched_scan_stop is called.
+ *
+ * @sched_scan_stop: Tell the hardware to stop an ongoing scheduled scan.
+ *
* @sw_scan_start: Notifier function that is called just before a software scan
* is started. Can be NULL, if the driver doesn't need this notification.
* The callback can sleep.
*
* @testmode_cmd: Implement a cfg80211 test mode command.
* The callback can sleep.
+ * @testmode_dump: Implement a cfg80211 test mode dump. The callback can sleep.
*
* @flush: Flush all pending frames from the hardware queue, making sure
* that the hardware queues are empty. If the parameter @drop is set
* @set_ringparam: Set tx and rx ring sizes.
*
* @get_ringparam: Get tx and rx ring current and maximum sizes.
+ *
+ * @tx_frames_pending: Check if there is any pending frame in the hardware
+ * queues before entering power save.
+ *
+ * @set_bitrate_mask: Set a mask of rates to be used for rate control selection
+ * when transmitting a frame. Currently only legacy rates are handled.
