150 * DMA services
151 *
152 * Theory of operation
153 *
154 * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
155 * of buffer descriptors, each of which points to one or more data buffers for
156 * the device to read from or fill. Driver and device exchange status of each
157 * queue via "read" and "write" pointers. Driver keeps minimum of 2 empty
158 * entries in each circular buffer, to protect against confusing empty and full
159 * queue states.
160 *
161 * The device reads or writes the data in the queues via the device's several
162 * DMA/FIFO channels. Each queue is mapped to a single DMA channel.
163 *
164 * For Tx queue, there are low mark and high mark limits. If, after queuing
165 * the packet for Tx, free space become < low mark, Tx queue stopped. When
166 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
167 * Tx queue resumed.
168 *
169 * The 4965 operates with up to 17 queues: One receive queue, one transmit
170 * queue (#4) for sending commands to the device firmware, and 15 other
171 * Tx queues that may be mapped to prioritized Tx DMA/FIFO channels.
172 *
