- *
- * 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.

- *
- * The set_key() callback in the &struct ieee80211_ops for a given
- * device is called to enable hardware acceleration of encryption and

- * the broadcast address for default keys, the other station's hardware
- * address for individual keys or the zero address for keys that will
- * be used only for transmission.
- * Multiple transmission keys with the same key index may be used when
- * VLANs are configured for an access point.
- *
- * The @local_address parameter will always be set to our own address,
- * this is only relevant if you support multiple local addresses.
- *
- * When transmitting, the TX control data will use the @hw_key_idx
- * selected by the driver by modifying the &struct ieee80211_key_conf
- * pointed to by the @key parameter to the set_key() function.
- *
- * The set_key() call for the %SET_KEY command should return 0 if
- * the key is now in use, -%EOPNOTSUPP or -%ENOSPC if it couldn't be
- * added; if you return 0 then hw_key_idx must be assigned to the
- * hardware key index, you are free to use the full u8 range.
- *
- * When the cmd is %DISABLE_KEY then it must succeed.
- *
- * Note that it is permissible to not decrypt a frame even if a key
- * for it has been uploaded to hardware, the stack will not make any
- * decision based on whether a key has been uploaded or not but rather
- * based on the receive flags.
- *
- * The &struct ieee80211_key_conf structure pointed to by the @key
- * parameter is guaranteed to be valid until another call to set_key()
- * removes it, but it can only be used as a cookie to differentiate

- * having as few frames as possible percolate through the stack is

- *
- * To achieve this, mac80211 uses filter flags (see below) to tell

- * passed to mac80211 and which should be filtered out.
- *
- * The configure_filter() callback is invoked with the parameters
- * @mc_count and @mc_list for the combined multicast address list
- * of all virtual interfaces, @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, i.e. you

-/**
- * struct ieee80211_ops - callbacks from mac80211 to the driver
- *
- * This structure contains various callbacks that the driver may
- * handle or, in some cases, must handle, for example to configure
- * the hardware to a new channel or to transmit a frame.
- *
- * @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.)
- *
- * @bss_info_changed: Handler for configuration requests related to BSS
- * parameters that may vary during BSS's lifespan, and may affect low
- * level driver (e.g. assoc/disassoc status, erp parameters).
- * This function should not be used if no BSS has been set, unless
- * for association indication. The @changed parameter indicates which
- * of the bss parameters has changed when a call is made. This callback
- * has to be atomic.
- *
- * @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.
- *
- * @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 registered
- * bands.
- *
- * @get_stats: return low-level statistics
- *
- * @get_tkip_seq: If your device implements TKIP encryption in hardware this
- * callback should be provided to read the TKIP transmit IVs (both IV32
- * and IV16) for the given key from hardware.
- *
- * @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_notify: Notifies low level driver about addition or removal
- * of assocaited station or AP.
- *
- * @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.
- * If the driver returns success (0) from this callback, it owns
- * the skb. That means the driver is responsible to kfree_skb() it.
- * The control structure is not dynamically allocated. That means the
- * driver does not own the pointer and if it needs it somewhere
- * outside of the context of this function, it must copy it
- * somewhere else.
- * 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.
- *
- * @conf_ht: Configures low level driver with 802.11n HT data. Must be atomic.
- *
- * @ampdu_action: Perform a certain A-MPDU action
- * The RA/TID combination determines the destination and TID we want
- * the ampdu action to be performed for. The action is defined through
- * ieee80211_ampdu_mlme_action. Starting sequence number (@ssn)
- * is the first frame we expect to perform the action on. notice
- * that TX/RX_STOP can pass NULL for this parameter.
