3434 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3435 * 2 empty entries always kept in the buffer to protect from overflow.
3436 *
3437 * For Tx queue, there are low mark and high mark limits. If, after queuing
bf79451e

3439 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
43f66a6c
JK		 3440 * Tx queue resumed.
3441 *
3442 * The IPW operates with six queues, one receive queue in the device's
3443 * sram, one transmit queue for sending commands to the device firmware,
bf79451e 3444 * and four transmit queues for data.
43f66a6c 3445 *
bf79451e 3446 * The four transmit queues allow for performing quality of service (qos)
43f66a6c 3447 * transmissions as per the 802.11 protocol. Currently Linux does not
bf79451e 3448 * provide a mechanism to the user for utilizing prioritized queues, so

43f66a6c
JK		 4782 * 0 to 31

4784 * Rx Queue Indexes
4785 * The host/firmware share two index registers for managing the Rx buffers.
4786 *
bf79451e
JG		 4787 * The READ index maps to the first position that the firmware may be writing
4788 * to -- the driver can read up to (but not including) this position and get
4789 * good data.
43f66a6c
JK		 4790 * The READ index is managed by the firmware once the card is enabled.
4791 *
4792 * The WRITE index maps to the last position the driver has read from -- the
4793 * position preceding WRITE is the last slot the firmware can place a packet.
4794 *
4795 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
bf79451e 4796 * WRITE = READ.
43f66a6c 4797 *
bf79451e 4798 * During initialization the host sets up the READ queue position to the first
43f66a6c
JK		 4799 * INDEX position, and WRITE to the last (READ - 1 wrapped)
4800 *
4801 * When the firmware places a packet in a buffer it will advance the READ index
4802 * and fire the RX interrupt. The driver can then query the READ index and
4803 * process as many packets as possible, moving the WRITE index forward as it
4804 * resets the Rx queue buffers with new memory.
bf79451e 4805 *
43f66a6c 4806 * The management in the driver is as follows:
bf79451e 4807 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
43f66a6c 4808 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
bf79451e 4809 * to replensish the ipw->rxq->rx_free.
43f66a6c
JK		 4810 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
4811 * ipw->rxq is replenished and the READ INDEX is updated (updating the
4812 * 'processed' and 'read' driver indexes as well)
4813 * + A received packet is processed and handed to the kernel network stack,
4814 * detached from the ipw->rxq. The driver 'processed' index is updated.
4815 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
bf79451e
JG		 4816 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
4817 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
43f66a6c
JK		 4818 * were enough free buffers and RX_STALLED is set it is cleared.
4819 *
4820 *

43f66a6c
