*
* Mac80211 uses the following numbers, which we get as from it
* by way of skb_get_queue_mapping(skb):
*
* VO 0
* VI 1
* BE 2
* BK 3
*
*
* Regular (not A-MPDU) frames are put into hardware queues corresponding
* to the FIFOs, see comments in iwl-prph.h. Aggregated frames get their
* own queue per aggregation session (RA/TID combination), such queues are
* set up to map into FIFOs too, for which we need an AC->FIFO mapping. In
* order to map frames to the right queue, we also need an AC->hw queue
* mapping. This is implemented here.
*
* Due to the way hw queues are set up (by the hw specific modules like
* iwl-4965.c, iwl-5000.c etc.), the AC->hw queue mapping is the identity
* mapping.

* @start_device: allocates and inits all the resources for the transport
* layer.
* @prepare_card_hw: claim the ownership on the HW. Will be called during
* probe.
* @tx_start: starts and configures all the Tx fifo - usually done once the fw
* is alive.
* @wake_any_queue: wake all the queues of a specfic context IWL_RXON_CTX_*
* @stop_device:stops the whole device (embedded CPU put to reset)
* @rx_free: frees the rx memory
* @tx_free: frees the tx memory
* @send_cmd:send a host command
* @send_cmd_pdu:send a host command: flags can be CMD_*
* @get_tx_cmd: returns a pointer to a new Tx cmd for the upper layer use
* @tx: send an skb
* @txq_agg_setup: setup a tx queue for AMPDU - will be called once the HW is
* @reclaim: free packet until ssn. Returns a list of freed packets.
* @tx_agg_alloc: allocate resources for a TX BA session
* @tx_agg_setup: setup a tx queue for AMPDU - will be called once the HW is
* ready and a successful ADDBA response has been received.
* @txq_agg_disable: de-configure a Tx queue to send AMPDUs
* @tx_agg_disable: de-configure a Tx queue to send AMPDUs
* @kick_nic: remove the RESET from the embedded CPU and let it run
* @sync_irq: the upper layer will typically disable interrupt and call this
* handler. After this handler returns, it is guaranteed that all
* the ISR / tasklet etc... have finished running and the transport
* layer shall not pass any Rx.
* @free: release all the ressource for the transport layer itself such as
* irq, tasklet etc...
* @stop_queue: stop a specific queue
* @check_stuck_queue: check if a specific queue is stuck
* @wait_tx_queue_empty: wait until all tx queues are empty
* @dbgfs_register: add the dbgfs files under this directory. Files will be
* automatically deleted.
* @suspend: stop the device unless WoWLAN is configured
* @resume: resume activity of the device

* 3 Promiscuous - When set, the WiLink receives all valid frames
