-/*
- * Rx theory of operation
- *
- * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
- * each of which point to Receive Buffers to be filled by the NIC. These get
- * used not only for Rx frames, but for any command response or notification
- * from the NIC. The driver and NIC manage the Rx buffers by means
- * of indexes into the circular buffer.
- *
- * Rx Queue Indexes
- * The host/firmware share two index registers for managing the Rx buffers.
- *
- * The READ index maps to the first position that the firmware may be writing
- * to -- the driver can read up to (but not including) this position and get
- * good data.
- * The READ index is managed by the firmware once the card is enabled.
- *
- * The WRITE index maps to the last position the driver has read from -- the
- * position preceding WRITE is the last slot the firmware can place a packet.
- *
- * The queue is empty (no good data) if WRITE = READ - 1, and is full if
- * WRITE = READ.
- *
- * During initialization, the host sets up the READ queue position to the first
- * INDEX position, and WRITE to the last (READ - 1 wrapped)
- *
- * When the firmware places a packet in a buffer, it will advance the READ index
- * and fire the RX interrupt. The driver can then query the READ index and
- * process as many packets as possible, moving the WRITE index forward as it
- * resets the Rx queue buffers with new memory.
- *
- * The management in the driver is as follows:
- * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When
- * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
- * to replenish the iwl->rxq->rx_free.
- * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
- * iwl->rxq is replenished and the READ INDEX is updated (updating the
- * 'processed' and 'read' driver indexes as well)
- * + A received packet is processed and handed to the kernel network stack,
- * detached from the iwl->rxq. The driver 'processed' index is updated.
- * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
- * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
- * INDEX is not incremented and iwl->status(RX_STALLED) is set. If there
- * were enough free buffers and RX_STALLED is set it is cleared.
- *
- *
- * Driver sequence:
- *
- * iwl_rx_queue_alloc() Allocates rx_free
- * iwl_rx_replenish() Replenishes rx_free list from rx_used, and calls
- * iwl_rx_queue_restock
- * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx
- * queue, updates firmware pointers, and updates
- * the WRITE index. If insufficient rx_free buffers
- * are available, schedules iwl_rx_replenish
- *
- * -- enable interrupts --
- * ISR - iwl_rx() Detach iwl_rx_mem_buffers from pool up to the
- * READ INDEX, detaching the SKB from the pool.
- * Moves the packet buffer from queue to rx_used.
- * Calls iwl_rx_queue_restock to refill any empty
- * slots.

+ * Rx theory of operation
+ *
+ * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
+ * each of which point to Receive Buffers to be filled by the NIC. These get
+ * used not only for Rx frames, but for any command response or notification
+ * from the NIC. The driver and NIC manage the Rx buffers by means
+ * of indexes into the circular buffer.
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two index registers for managing the Rx buffers.
+ *
+ * The READ index maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ index is managed by the firmware once the card is enabled.
+ *
+ * The WRITE index maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization, the host sets up the READ queue position to the first
+ * INDEX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer, it will advance the READ index
+ * and fire the RX interrupt. The driver can then query the READ index and
+ * process as many packets as possible, moving the WRITE index forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When
+ * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ * to replenish the iwl->rxq->rx_free.
+ * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
+ * iwl->rxq is replenished and the READ INDEX is updated (updating the
+ * 'processed' and 'read' driver indexes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ * detached from the iwl->rxq. The driver 'processed' index is updated.
+ * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
+ * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
+ * INDEX is not incremented and iwl->status(RX_STALLED) is set. If there
+ * were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * iwl_rx_queue_alloc() Allocates rx_free
+ * iwl_rx_replenish() Replenishes rx_free list from rx_used, and calls
+ * iwl_rx_queue_restock
+ * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx
+ * queue, updates firmware pointers, and updates
+ * the WRITE index. If insufficient rx_free buffers
+ * are available, schedules iwl_rx_replenish
+ *
+ * -- enable interrupts --
+ * ISR - iwl_rx() Detach iwl_rx_mem_buffers from pool up to the
+ * READ INDEX, detaching the SKB from the pool.
+ * Moves the packet buffer from queue to rx_used.
+ * Calls iwl_rx_queue_restock to refill any empty

+ * queue via "read" and "write" pointers. Driver keeps minimum of 2 empty

+ * queue states.
+ *
+ * The device reads or writes the data in the queues via the device's several
+ * DMA/FIFO channels. Each queue is mapped to a single DMA channel.
+ *
+ * For Tx queue, there are low mark and high mark limits. If, after queuing
+ * the packet for Tx, free space become < low mark, Tx queue stopped. When
+ * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
+ * Tx queue resumed.

- * DMA services
- *
- * Theory of operation
- *
- * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
- * of buffer descriptors, each of which points to one or more data buffers for
- * the device to read from or fill. Driver and device exchange status of each
- * queue via "read" and "write" pointers. Driver keeps minimum of 2 empty
- * entries in each circular buffer, to protect against confusing empty and full
- * queue states.
- *
- * The device reads or writes the data in the queues via the device's several
- * DMA/FIFO channels. Each queue is mapped to a single DMA channel.
- *
- * For Tx queue, there are low mark and high mark limits. If, after queuing
- * the packet for Tx, free space become < low mark, Tx queue stopped. When
- * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
- * Tx queue resumed.
