3591 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3592 * 2 empty entries always kept in the buffer to protect from overflow.
3594 * For Tx queue, there are low mark and high mark limits. If, after queuing
3595 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3596 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
3599 * The IPW operates with six queues, one receive queue in the device's
3600 * sram, one transmit queue for sending commands to the device firmware,
3601 * and four transmit queues for data.
3603 * The four transmit queues allow for performing quality of service (qos)
3604 * transmissions as per the 802.11 protocol. Currently Linux does not
3605 * provide a mechanism to the user for utilizing prioritized queues, so
3606 * we only utilize the first data transmit queue (queue1).
3610 * Driver allocates buffers of this size for Rx

5008 * Rx theory of operation
5010 * The host allocates 32 DMA target addresses and passes the host address
5011 * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
5015 * The host/firmware share two index registers for managing the Rx buffers.
5017 * The READ index maps to the first position that the firmware may be writing
5018 * to -- the driver can read up to (but not including) this position and get
5020 * The READ index is managed by the firmware once the card is enabled.
5022 * The WRITE index maps to the last position the driver has read from -- the
5023 * position preceding WRITE is the last slot the firmware can place a packet.
5025 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
5028 * During initialization the host sets up the READ queue position to the first
5029 * INDEX position, and WRITE to the last (READ - 1 wrapped)
5031 * When the firmware places a packet in a buffer it will advance the READ index
5032 * and fire the RX interrupt. The driver can then query the READ index and
5033 * process as many packets as possible, moving the WRITE index forward as it
5034 * resets the Rx queue buffers with new memory.
5036 * The management in the driver is as follows:
5037 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
5038 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
5039 * to replensish the ipw->rxq->rx_free.
5040 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
5041 * ipw->rxq is replenished and the READ INDEX is updated (updating the
5042 * 'processed' and 'read' driver indexes as well)
5043 * + A received packet is processed and handed to the kernel network stack,
5044 * detached from the ipw->rxq. The driver 'processed' index is updated.
5045 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
5046 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
5047 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
5048 * were enough free buffers and RX_STALLED is set it is cleared.
5053 * ipw_rx_queue_alloc() Allocates rx_free
5054 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
5055 * ipw_rx_queue_restock
5056 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
5057 * queue, updates firmware pointers, and updates
5058 * the WRITE index. If insufficient rx_free buffers
5059 * are available, schedules ipw_rx_queue_replenish
5061 * -- enable interrupts --
5062 * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the

5065 * Calls ipw_rx_queue_restock to refill any empty
5072 * If there are slots in the RX queue that need to be restocked,
5073 * and we have free pre-allocated buffers, fill the ranks as much
5074 * as we can pulling from rx_free.
