- * could be updated to provide support for such format assuming this would
- * optimize the performance, e.g., by removing need to re-allocation and

+ * As a general rule, when frames are passed between mac80211 and the driver,

+ *
+ * There are, however, various exceptions to this rule for advanced features:
+ *
+ * The first exception is for hardware encryption and decryption offload
+ * where the IV/ICV may or may not be generated in hardware.
+ *
+ * Secondly, when the hardware handles fragmentation, the frame handed to
+ * the driver from mac80211 is the MSDU, not the MPDU.
+ *
+ * Finally, for received frames, the driver is able to indicate that it has
+ * filled a radiotap header and put that in front of the frame; if it does
+ * not do so then mac80211 may add this under certain circumstances.

+ *
+ * @tx: Handler that 802.11 module calls for each transmitted frame.
+ *	skb contains the buffer starting from the IEEE 802.11 header.
+ *	The low-level driver should send the frame out based on
+ *	configuration in the TX control data. Must be implemented and
+ *	atomic.
+ *
+ * @start: Called before the first netdevice attached to the hardware
+ *	is enabled. This should turn on the hardware and must turn on
+ *	frame reception (for possibly enabled monitor interfaces.)
+ *	Returns negative error codes, these may be seen in userspace,
+ *	or zero.
+ *	When the device is started it should not have a MAC address
+ *	to avoid acknowledging frames before a non-monitor device
+ *	is added.
+ *	Must be implemented.
+ *
+ * @stop: Called after last netdevice attached to the hardware
+ *	is disabled. This should turn off the hardware (at least
+ *	it must turn off frame reception.)
+ *	May be called right after add_interface if that rejects
+ *	an interface.
+ *	Must be implemented.
+ *
+ * @add_interface: Called when a netdevice attached to the hardware is
+ *	enabled. Because it is not called for monitor mode devices, @open
+ *	and @stop must be implemented.
+ *	The driver should perform any initialization it needs before
+ *	the device can be enabled. The initial configuration for the
+ *	interface is given in the conf parameter.
+ *	The callback may refuse to add an interface by returning a
+ *	negative error code (which will be seen in userspace.)
+ *	Must be implemented.
+ *
+ * @remove_interface: Notifies a driver that an interface is going down.
+ *	The @stop callback is called after this if it is the last interface
+ *	and no monitor interfaces are present.
+ *	When all interfaces are removed, the MAC address in the hardware
+ *	must be cleared so the device no longer acknowledges packets,
+ *	the mac_addr member of the conf structure is, however, set to the
+ *	MAC address of the device going away.
+ *	Hence, this callback must be implemented.
+ *
+ * @config: Handler for configuration requests. IEEE 802.11 code calls this
+ *	function to change hardware configuration, e.g., channel.
+ *
+ * @config_interface: Handler for configuration requests related to interfaces
+ *	(e.g. BSSID changes.)
+ *
+ * @configure_filter: Configure the device's RX filter.
+ *	See the section "Frame filtering" for more information.
+ *	This callback must be implemented and atomic.
+ *
+ * @set_tim: Set TIM bit. If the hardware/firmware takes care of beacon
+ *	generation (that is, %IEEE80211_HW_HOST_GEN_BEACON_TEMPLATE is set)
+ *	mac80211 calls this function when a TIM bit must be set or cleared
+ *	for a given AID. Must be atomic.
+ *
+ * @set_key: See the section "Hardware crypto acceleration"
+ *	This callback can sleep, and is only called between add_interface
+ *	and remove_interface calls, i.e. while the interface with the
+ *	given local_address is enabled.
+ *
+ * @set_ieee8021x: Enable/disable IEEE 802.1X. This item requests wlan card
+ *	to pass unencrypted EAPOL-Key frames even when encryption is
+ *	configured. If the wlan card does not require such a configuration,
+ *	this function pointer can be set to NULL.
+ *
+ * @set_port_auth: Set port authorization state (IEEE 802.1X PAE) to be
+ *	authorized (@authorized=1) or unauthorized (=0). This function can be
+ *	used if the wlan hardware or low-level driver implements PAE.
+ *	mac80211 will filter frames based on authorization state in any case,
+ *	so this function pointer can be NULL if low-level driver does not
+ *	require event notification about port state changes.
+ *
+ * @hw_scan: Ask the hardware to service the scan request, no need to start
+ *	the scan state machine in stack.
+ *
+ * @get_stats: return low-level statistics
+ *
+ * @set_privacy_invoked: For devices that generate their own beacons and probe
+ *	response or association responses this updates the state of privacy_invoked
+ *	returns 0 for success or an error number.
+ *
+ * @get_sequence_counter: For devices that have internal sequence counters this
+ *	callback allows mac80211 to access the current value of a counter.
+ *	This callback seems not well-defined, tell us if you need it.
+ *
+ * @set_rts_threshold: Configuration of RTS threshold (if device needs it)
+ *
+ * @set_frag_threshold: Configuration of fragmentation threshold. Assign this if
+ *	the device does fragmentation by itself; if this method is assigned then
+ *	the stack will not do fragmentation.
+ *
+ * @set_retry_limit: Configuration of retry limits (if device needs it)
+ *
+ * @sta_table_notification: Number of STAs in STA table notification. Must
+ *	be atomic.
+ *
+ * @erp_ie_changed: Handle ERP IE change notifications. Must be atomic.
+ *
+ * @conf_tx: Configure TX queue parameters (EDCF (aifs, cw_min, cw_max),
+ *	bursting) for a hardware TX queue. The @queue parameter uses the
+ *	%IEEE80211_TX_QUEUE_* constants. Must be atomic.
+ *
+ * @get_tx_stats: Get statistics of the current TX queue status. This is used
+ *	to get number of currently queued packets (queue length), maximum queue
+ *	size (limit), and total number of packets sent using each TX queue
+ *	(count). This information is used for WMM to find out which TX
+ *	queues have room for more packets and by hostapd to provide
+ *	statistics about the current queueing state to external programs.
+ *
+ * @get_tsf: Get the current TSF timer value from firmware/hardware. Currently,
+ *	this is only used for IBSS mode debugging and, as such, is not a
+ *	required function. Must be atomic.
+ *
+ * @reset_tsf: Reset the TSF timer and allow firmware/hardware to synchronize
+ *	with other STAs in the IBSS. This is only used in IBSS mode. This
+ *	function is optional if the firmware/hardware takes full care of
+ *	TSF synchronization.
+ *
+ * @beacon_update: Setup beacon data for IBSS beacons. Unlike access point,
+ *	IBSS uses a fixed beacon frame which is configured using this
+ *	function. This handler is required only for IBSS mode.
+ *
+ * @tx_last_beacon: Determine whether the last IBSS beacon was sent by us.
+ *	This is needed only for IBSS mode and the result of this function is
+ *	used to determine whether to reply to Probe Requests.
