3699 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3700 * 2 empty entries always kept in the buffer to protect from overflow.
3702 * For Tx queue, there are low mark and high mark limits. If, after queuing
3703 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3704 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
3707 * The IPW operates with six queues, one receive queue in the device's
3708 * sram, one transmit queue for sending commands to the device firmware,
3709 * and four transmit queues for data.
3711 * The four transmit queues allow for performing quality of service (qos)
3712 * transmissions as per the 802.11 protocol. Currently Linux does not
3713 * provide a mechanism to the user for utilizing prioritized queues, so
3714 * we only utilize the first data transmit queue (queue1).

5091 * Rx theory of operation
5093 * The host allocates 32 DMA target addresses and passes the host address
5094 * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
5098 * The host/firmware share two index registers for managing the Rx buffers.
5100 * The READ index maps to the first position that the firmware may be writing
5101 * to -- the driver can read up to (but not including) this position and get
5103 * The READ index is managed by the firmware once the card is enabled.
5105 * The WRITE index maps to the last position the driver has read from -- the
5106 * position preceding WRITE is the last slot the firmware can place a packet.
5108 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
5111 * During initialization the host sets up the READ queue position to the first
5112 * INDEX position, and WRITE to the last (READ - 1 wrapped)
5114 * When the firmware places a packet in a buffer it will advance the READ index
5115 * and fire the RX interrupt. The driver can then query the READ index and
5116 * process as many packets as possible, moving the WRITE index forward as it
5117 * resets the Rx queue buffers with new memory.
5119 * The management in the driver is as follows:
5120 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
5121 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
5122 * to replensish the ipw->rxq->rx_free.
5123 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
5124 * ipw->rxq is replenished and the READ INDEX is updated (updating the
5125 * 'processed' and 'read' driver indexes as well)
5126 * + A received packet is processed and handed to the kernel network stack,
5127 * detached from the ipw->rxq. The driver 'processed' index is updated.
5128 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
5129 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
5130 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
5131 * were enough free buffers and RX_STALLED is set it is cleared.
5136 * ipw_rx_queue_alloc() Allocates rx_free
5137 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
5138 * ipw_rx_queue_restock
5139 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
5140 * queue, updates firmware pointers, and updates
5141 * the WRITE index. If insufficient rx_free buffers
5142 * are available, schedules ipw_rx_queue_replenish
5144 * -- enable interrupts --
5145 * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the

5148 * Calls ipw_rx_queue_restock to refill any empty
5155 * If there are slots in the RX queue that need to be restocked,
5156 * and we have free pre-allocated buffers, fill the ranks as much
5157 * as we can pulling from rx_free.
