3481 * Theory of operation
3483 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3484 * 2 empty entries always kept in the buffer to protect from overflow.
3486 * For Tx queue, there are low mark and high mark limits. If, after queuing
3487 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3488 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
3491 * The IPW operates with six queues, one receive queue in the device's
3492 * sram, one transmit queue for sending commands to the device firmware,
3493 * and four transmit queues for data.
3495 * The four transmit queues allow for performing quality of service (qos)
3496 * transmissions as per the 802.11 protocol. Currently Linux does not
3497 * provide a mechanism to the user for utilizing prioritized queues, so
3498 * we only utilize the first data transmit queue (queue1).

4834 * The host/firmware share two index registers for managing the Rx buffers.
4836 * The READ index maps to the first position that the firmware may be writing
4837 * to -- the driver can read up to (but not including) this position and get
4839 * The READ index is managed by the firmware once the card is enabled.
4841 * The WRITE index maps to the last position the driver has read from -- the
4842 * position preceding WRITE is the last slot the firmware can place a packet.
4844 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
4847 * During initialization the host sets up the READ queue position to the first
4848 * INDEX position, and WRITE to the last (READ - 1 wrapped)
4850 * When the firmware places a packet in a buffer it will advance the READ index
4851 * and fire the RX interrupt. The driver can then query the READ index and
4852 * process as many packets as possible, moving the WRITE index forward as it
4853 * resets the Rx queue buffers with new memory.
4855 * The management in the driver is as follows:
4856 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
4857 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
4858 * to replensish the ipw->rxq->rx_free.
4859 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
4860 * ipw->rxq is replenished and the READ INDEX is updated (updating the
4861 * 'processed' and 'read' driver indexes as well)
4862 * + A received packet is processed and handed to the kernel network stack,
4863 * detached from the ipw->rxq. The driver 'processed' index is updated.
4864 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
4865 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
4866 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
4867 * were enough free buffers and RX_STALLED is set it is cleared.
4872 * ipw_rx_queue_alloc() Allocates rx_free
4873 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
4874 * ipw_rx_queue_restock
4875 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
4876 * queue, updates firmware pointers, and updates
4877 * the WRITE index. If insufficient rx_free buffers
4878 * are available, schedules ipw_rx_queue_replenish
4880 * -- enable interrupts --
4881 * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
4882 * READ INDEX, detaching the SKB from the pool.
4883 * Moves the packet buffer from queue to rx_used.
4884 * Calls ipw_rx_queue_restock to refill any empty
4891 * If there are slots in the RX queue that need to be restocked,
4892 * and we have free pre-allocated buffers, fill the ranks as much
4893 * as we can pulling from rx_free.
