3423 * For Tx queue, there are low mark and high mark limits. If, after queuing
3424 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3425 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
3428 * The IPW operates with six queues, one receive queue in the device's
3429 * sram, one transmit queue for sending commands to the device firmware,
3430 * and four transmit queues for data.
3432 * The four transmit queues allow for performing quality of service (qos)
3433 * transmissions as per the 802.11 protocol. Currently Linux does not
3434 * provide a mechanism to the user for utilizing prioritized queues, so
3435 * we only utilize the first data transmit queue (queue1).

4771 * The host/firmware share two index registers for managing the Rx buffers.
4773 * The READ index maps to the first position that the firmware may be writing
4774 * to -- the driver can read up to (but not including) this position and get
4776 * The READ index is managed by the firmware once the card is enabled.
4778 * The WRITE index maps to the last position the driver has read from -- the
4779 * position preceding WRITE is the last slot the firmware can place a packet.
4781 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
4784 * During initialization the host sets up the READ queue position to the first
4785 * INDEX position, and WRITE to the last (READ - 1 wrapped)
4787 * When the firmware places a packet in a buffer it will advance the READ index
4788 * and fire the RX interrupt. The driver can then query the READ index and
4789 * process as many packets as possible, moving the WRITE index forward as it
4790 * resets the Rx queue buffers with new memory.
4792 * The management in the driver is as follows:
4793 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
4794 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
4795 * to replensish the ipw->rxq->rx_free.
4796 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
4797 * ipw->rxq is replenished and the READ INDEX is updated (updating the
4798 * 'processed' and 'read' driver indexes as well)
4799 * + A received packet is processed and handed to the kernel network stack,
4800 * detached from the ipw->rxq. The driver 'processed' index is updated.
4801 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
4802 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
4803 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
4804 * were enough free buffers and RX_STALLED is set it is cleared.
4809 * ipw_rx_queue_alloc() Allocates rx_free
4810 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
4811 * ipw_rx_queue_restock
4812 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
4813 * queue, updates firmware pointers, and updates
