- * when a vif is added to mac80211. This callback and
- * @remove_interface_debugfs should be within a CONFIG_MAC80211_DEBUGFS
- * conditional. @remove_interface_debugfs must be provided for cleanup.

- * @remove_interface_debugfs: Remove the debugfs files which were added using
- * @add_interface_debugfs. This callback must remove all debugfs entries
- * that were added because mac80211 only removes interface debugfs when the
- * interface is destroyed, not when it is removed from the driver.
- * This callback can sleep.
- *
* @config: Handler for configuration requests. IEEE 802.11 code calls this
* function to change hardware configuration, e.g., channel.
* This function should never fail but returns a negative error code
* See the section "Frame filtering" for more information.
* This callback must be implemented and can sleep.
*
+ * @set_multicast_list: Configure the device's interface specific RX multicast
+ * filter. This callback is optional. This callback must be atomic.
+ *
* @set_tim: Set TIM bit. mac80211 calls this function when a TIM bit
* must be set or cleared for a given STA. Must be atomic.
*
* @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
- * to %true, pending frames may be dropped. The callback can sleep.
+ * that the hardware queues are empty. The @queues parameter is a bitmap
+ * of queues to flush, which is useful if different virtual interfaces
+ * use different hardware queues; it may also indicate all queues.
+ * If the parameter @drop is set to %true, pending frames may be dropped.
+ * The callback can sleep.
*
* @channel_switch: Drivers that need (or want) to offload the channel
* switch operation for CSAs received from the AP may implement this
* 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

- * ieee80211_sta_eosp_irqsafe() to inform mac80211 of the end of the SP.
+ * ieee80211_sta_eosp() 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
* 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
