*
* Theory of operation
*
- * A queue is a circular buffers with 'Read' and 'Write' pointers.
- * 2 empty entries always kept in the buffer to protect from overflow.
+ * 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.
*
- * The IWL operates with six queues, one receive queue in the device's
- * sram, one transmit queue for sending commands to the device firmware,
- * and four transmit queues for data.
+ * The 4965 operates with up to 17 queues: One receive queue, one transmit
+ * queue (#4) for sending commands to the device firmware, and 15 other
+ * Tx queues that may be mapped to prioritized Tx DMA/FIFO channels.
+ *
+ * See more detailed info in iwl-4965-hw.h.

* Rx theory of operation
*
- * The host allocates 32 DMA target addresses and passes the host address

+ * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),

+ * of indexes into the circular buffer.
*
* Rx Queue Indexes
* The host/firmware share two index registers for managing the Rx buffers.
* The queue is empty (no good data) if WRITE = READ - 1, and is full if

* 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 replensish the iwl->rxq->rx_free.

* 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,
*
* Driver sequence:
*
