3428 *
3429 * Theory of operation
3430 *
3431 * A queue is a circular buffers with 'Read' and 'Write' pointers.
3432 * 2 empty entries always kept in the buffer to protect from overflow.
3433 *
3434 * For Tx queue, there are low mark and high mark limits. If, after queuing
Jeff Garzikbf794512005-07-31 13:07:26 -04003435 * the packet for Tx, free space become < low mark, Tx queue stopped. When
3436 * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
James Ketrenos43f66a62005-03-25 12:31:53 -06003437 * Tx queue resumed.
3438 *
3439 * The IPW operates with six queues, one receive queue in the device's
3440 * sram, one transmit queue for sending commands to the device firmware,
Jeff Garzikbf794512005-07-31 13:07:26 -04003441 * and four transmit queues for data.
James Ketrenos43f66a62005-03-25 12:31:53 -06003442 *
Jeff Garzikbf794512005-07-31 13:07:26 -04003443 * The four transmit queues allow for performing quality of service (qos)
James Ketrenos43f66a62005-03-25 12:31:53 -06003444 * transmissions as per the 802.11 protocol. Currently Linux does not
Jeff Garzikbf794512005-07-31 13:07:26 -04003445 * provide a mechanism to the user for utilizing prioritized queues, so
James Ketrenos43f66a62005-03-25 12:31:53 -06003446 * we only utilize the first data transmit queue (queue1).

4763 * The host allocates 32 DMA target addresses and passes the host address

4766 *
4767 * Rx Queue Indexes
4768 * The host/firmware share two index registers for managing the Rx buffers.
4769 *
Jeff Garzikbf794512005-07-31 13:07:26 -04004770 * The READ index maps to the first position that the firmware may be writing
4771 * to -- the driver can read up to (but not including) this position and get
4772 * good data.
James Ketrenos43f66a62005-03-25 12:31:53 -06004773 * The READ index is managed by the firmware once the card is enabled.
4774 *
4775 * The WRITE index maps to the last position the driver has read from -- the
4776 * position preceding WRITE is the last slot the firmware can place a packet.
4777 *
4778 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
Jeff Garzikbf794512005-07-31 13:07:26 -04004779 * WRITE = READ.
James Ketrenos43f66a62005-03-25 12:31:53 -06004780 *
Jeff Garzikbf794512005-07-31 13:07:26 -04004781 * During initialization the host sets up the READ queue position to the first
James Ketrenos43f66a62005-03-25 12:31:53 -06004782 * INDEX position, and WRITE to the last (READ - 1 wrapped)
4783 *
4784 * When the firmware places a packet in a buffer it will advance the READ index
4785 * and fire the RX interrupt. The driver can then query the READ index and
4786 * process as many packets as possible, moving the WRITE index forward as it
4787 * resets the Rx queue buffers with new memory.

4794 * ipw->rxq is replenished and the READ INDEX is updated (updating the
4795 * 'processed' and 'read' driver indexes as well)
4796 * + A received packet is processed and handed to the kernel network stack,
4797 * detached from the ipw->rxq. The driver 'processed' index is updated.
4798 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
Jeff Garzikbf794512005-07-31 13:07:26 -04004799 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
