/**
* DOC: Operational mode - what is it ?
*
* The operational mode (a.k.a. op_mode) is the layer that implements
* mac80211's handlers. It knows two APIs: mac80211's and the fw's. It uses
* the transport API to access the HW. The op_mode doesn't need to know how the
* underlying HW works, since the transport layer takes care of that.
*
* There can be several op_mode: i.e. different fw APIs will require two
* different op_modes. This is why the op_mode is virtualized.
*/
/**
* DOC: Life cycle of the Operational mode
*
* The operational mode has a very simple life cycle.
*
* 1) The driver layer (iwl-drv.c) chooses the op_mode based on the
* capabilities advertised by the fw file (in TLV format).
* 2) The driver layer starts the op_mode (ops->start)
* 3) The op_mode registers mac80211
* 4) The op_mode is governed by mac80211
* 5) The driver layer stops the op_mode
*/
/**
* struct iwl_op_mode_ops - op_mode specific operations
*
* The op_mode exports its ops so that external components can start it and
* interact with it. The driver layer typically calls the start and stop
* handlers, the transport layer calls the others.
*
* All the handlers MUST be implemented, except @rx_rss which can be left
* out *iff* the opmode will never run on hardware with multi-queue capability.
*
* @start: start the op_mode. The transport layer is already allocated.
* May sleep
* @stop: stop the op_mode. Must free all the memory allocated.
* May sleep
* @rx: Rx notification to the op_mode. rxb is the Rx buffer itself. Cmd is the
* HCMD this Rx responds to. Can't sleep.
* @rx_rss: data queue RX notification to the op_mode, for (data) notifications
* received on the RSS queue(s). The queue parameter indicates which of the
* RSS queues received this frame; it will always be non-zero.
* This method must not sleep.
* @async_cb: called when an ASYNC command with CMD_WANT_ASYNC_CALLBACK set
* completes. Must be atomic.
* @queue_full: notifies that a HW queue is full.
* Must be atomic and called with BH disabled.
* @queue_not_full: notifies that a HW queue is not full any more.
* Must be atomic and called with BH disabled.
* @hw_rf_kill:notifies of a change in the HW rf kill switch. True means that
* the radio is killed. Return %true if the device should be stopped by
* the transport immediately after the call. May sleep.
* @free_skb: allows the transport layer to free skbs that haven't been
* reclaimed by the op_mode. This can happen when the driver is freed and
* there are Tx packets pending in the transport layer.
* Must be atomic
* @nic_error: error notification. Must be atomic and must be called with BH
* disabled.
* @cmd_queue_full: Called when the command queue gets full. Must be atomic and
* called with BH disabled.
* @nic_config: configure NIC, called before firmware is started.
* May sleep
* @wimax_active: invoked when WiMax becomes active. May sleep
* @enter_d0i3: configure the fw to enter d0i3. return 1 to indicate d0i3
* entrance is aborted (e.g. due to held reference). May sleep.
* @exit_d0i3: configure the fw to exit d0i3. May sleep.
