3616 * Theory of operation
3618 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3619 * 2 empty entries always kept in the buffer to protect from overflow.
3621 * For Tx queue, there are low mark and high mark limits. If, after queuing
3622 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3623 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
3626 * The IPW operates with six queues, one receive queue in the device's
3627 * sram, one transmit queue for sending commands to the device firmware,
3628 * and four transmit queues for data.
3630 * The four transmit queues allow for performing quality of service (qos)
3631 * transmissions as per the 802.11 protocol. Currently Linux does not
3632 * provide a mechanism to the user for utilizing prioritized queues, so
3633 * we only utilize the first data transmit queue (queue1).
3637 * Driver allocates buffers of this size for Rx
3641 * ipw_rx_queue_space - Return number of free slots available in queue.

5039 * Rx theory of operation
5041 * The host allocates 32 DMA target addresses and passes the host address
5042 * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
5046 * The host/firmware share two index registers for managing the Rx buffers.
5048 * The READ index maps to the first position that the firmware may be writing
5049 * to -- the driver can read up to (but not including) this position and get
5051 * The READ index is managed by the firmware once the card is enabled.
5053 * The WRITE index maps to the last position the driver has read from -- the
5054 * position preceding WRITE is the last slot the firmware can place a packet.
5056 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
5059 * During initialization the host sets up the READ queue position to the first
5060 * INDEX position, and WRITE to the last (READ - 1 wrapped)
5062 * When the firmware places a packet in a buffer it will advance the READ index
5063 * and fire the RX interrupt. The driver can then query the READ index and
5064 * process as many packets as possible, moving the WRITE index forward as it
5065 * resets the Rx queue buffers with new memory.
5067 * The management in the driver is as follows:
5068 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
5069 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
5070 * to replensish the ipw->rxq->rx_free.
5071 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
5072 * ipw->rxq is replenished and the READ INDEX is updated (updating the
5073 * 'processed' and 'read' driver indexes as well)
5074 * + A received packet is processed and handed to the kernel network stack,
5075 * detached from the ipw->rxq. The driver 'processed' index is updated.
5076 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
5077 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
5078 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
5079 * were enough free buffers and RX_STALLED is set it is cleared.
5084 * ipw_rx_queue_alloc() Allocates rx_free
5085 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
5086 * ipw_rx_queue_restock
5087 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
5088 * queue, updates firmware pointers, and updates
5089 * the WRITE index. If insufficient rx_free buffers
5090 * are available, schedules ipw_rx_queue_replenish

5093 * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the

5103 * If there are slots in the RX queue that need to be restocked,
5104 * and we have free pre-allocated buffers, fill the ranks as much
5105 * as we can pulling from rx_free.
