3537 * Theory of operation
3539 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3540 * 2 empty entries always kept in the buffer to protect from overflow.
3542 * For Tx queue, there are low mark and high mark limits. If, after queuing
3543 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3544 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
3547 * The IPW operates with six queues, one receive queue in the device's
3548 * sram, one transmit queue for sending commands to the device firmware,
3549 * and four transmit queues for data.
3551 * The four transmit queues allow for performing quality of service (qos)
3552 * transmissions as per the 802.11 protocol. Currently Linux does not
3553 * provide a mechanism to the user for utilizing prioritized queues, so
3554 * we only utilize the first data transmit queue (queue1).
3558 * Driver allocates buffers of this size for Rx

4924 * The READ index is managed by the firmware once the card is enabled.
4926 * The WRITE index maps to the last position the driver has read from -- the
4927 * position preceding WRITE is the last slot the firmware can place a packet.

4936 * and fire the RX interrupt. The driver can then query the READ index and
4937 * process as many packets as possible, moving the WRITE index forward as it
4938 * resets the Rx queue buffers with new memory.

4941 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
4942 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
4943 * to replensish the ipw->rxq->rx_free.
4944 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
4945 * ipw->rxq is replenished and the READ INDEX is updated (updating the
4946 * 'processed' and 'read' driver indexes as well)
4947 * + A received packet is processed and handed to the kernel network stack,
4948 * detached from the ipw->rxq. The driver 'processed' index is updated.
4949 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
4950 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
4951 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
4952 * were enough free buffers and RX_STALLED is set it is cleared.
4957 * ipw_rx_queue_alloc() Allocates rx_free
4958 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
4959 * ipw_rx_queue_restock
4960 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
4961 * queue, updates firmware pointers, and updates
4962 * the WRITE index. If insufficient rx_free buffers
4963 * are available, schedules ipw_rx_queue_replenish
4965 * -- enable interrupts --
4966 * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
4967 * READ INDEX, detaching the SKB from the pool.
4968 * Moves the packet buffer from queue to rx_used.
4969 * Calls ipw_rx_queue_restock to refill any empty
4976 * If there are slots in the RX queue that need to be restocked,
4977 * and we have free pre-allocated buffers, fill the ranks as much
4978 * as we can pulling from rx_free.
