- * 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.
- *
- * 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.

- * For example, iwl3945_priv->eeprom39.band_3_channels[4] from the band_3

- * information into priv->channel_info_24/52 and priv->channel_map_24/52
- *
- * channel_map_24/52 provides the index in the channel_info array for a

- *
- * A value of 0xfe in the channel_map indicates that the channel is not
