* 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 3945 operates with six queues: One receive queue, one transmit queue
+ * (#4) for sending commands to the device firmware, and four transmit queues
+ * (#0-3) for data tx via EDCA. An additional 2 HCCA queues are unused.
