3285 * For Tx queue, there are low mark and high mark limits. If, after queuing
3286 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3287 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
3290 * The IPW operates with six queues, one receive queue in the device's
3291 * sram, one transmit queue for sending commands to the device firmware,
3292 * and four transmit queues for data.
3294 * The four transmit queues allow for performing quality of service (qos)
3295 * transmissions as per the 802.11 protocol. Currently Linux does not
3296 * provide a mechanism to the user for utilizing prioritized queues, so

4624 * The host/firmware share two index registers for managing the Rx buffers.
4626 * The READ index maps to the first position that the firmware may be writing
4627 * to -- the driver can read up to (but not including) this position and get
4629 * The READ index is managed by the firmware once the card is enabled.
4631 * The WRITE index maps to the last position the driver has read from -- the
4632 * position preceding WRITE is the last slot the firmware can place a packet.
4634 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
4637 * During initialization the host sets up the READ queue position to the first
4638 * INDEX position, and WRITE to the last (READ - 1 wrapped)
4640 * When the firmware places a packet in a buffer it will advance the READ index
4641 * and fire the RX interrupt. The driver can then query the READ index and
4642 * process as many packets as possible, moving the WRITE index forward as it
4643 * resets the Rx queue buffers with new memory.
4645 * The management in the driver is as follows:
4646 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
4647 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
4648 * to replensish the ipw->rxq->rx_free.
4649 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
4650 * ipw->rxq is replenished and the READ INDEX is updated (updating the
4651 * 'processed' and 'read' driver indexes as well)
4652 * + A received packet is processed and handed to the kernel network stack,
4653 * detached from the ipw->rxq. The driver 'processed' index is updated.
4654 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
4655 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
4656 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
4657 * were enough free buffers and RX_STALLED is set it is cleared.
4662 * ipw_rx_queue_alloc() Allocates rx_free
4663 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
4664 * ipw_rx_queue_restock
4665 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
4666 * queue, updates firmware pointers, and updates
4667 * the WRITE index. If insufficient rx_free buffers
4668 * are available, schedules ipw_rx_queue_replenish
