JK		 5024 * Rx theory of operation
5025 *
5026 * The host allocates 32 DMA target addresses and passes the host address
b095c381 5027 * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
43f66a6c
JK		 5028 * 0 to 31
5029 *
5030 * Rx Queue Indexes
5031 * The host/firmware share two index registers for managing the Rx buffers.
5032 *
bf79451e
JG		 5033 * The READ index maps to the first position that the firmware may be writing
5034 * to -- the driver can read up to (but not including) this position and get
5035 * good data.
43f66a6c
JK		 5036 * The READ index is managed by the firmware once the card is enabled.
5037 *
5038 * The WRITE index maps to the last position the driver has read from -- the
5039 * position preceding WRITE is the last slot the firmware can place a packet.
5040 *
5041 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
bf79451e 5042 * WRITE = READ.
43f66a6c 5043 *
bf79451e 5044 * During initialization the host sets up the READ queue position to the first
43f66a6c
JK		 5045 * INDEX position, and WRITE to the last (READ - 1 wrapped)
5046 *
5047 * When the firmware places a packet in a buffer it will advance the READ index
5048 * and fire the RX interrupt. The driver can then query the READ index and
5049 * process as many packets as possible, moving the WRITE index forward as it
5050 * resets the Rx queue buffers with new memory.
bf79451e 5051 *
43f66a6c 5052 * The management in the driver is as follows:
bf79451e 5053 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
43f66a6c 5054 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
bf79451e 5055 * to replensish the ipw->rxq->rx_free.
43f66a6c
JK		 5056 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
5057 * ipw->rxq is replenished and the READ INDEX is updated (updating the
5058 * 'processed' and 'read' driver indexes as well)
5059 * + A received packet is processed and handed to the kernel network stack,
5060 * detached from the ipw->rxq. The driver 'processed' index is updated.
5061 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
bf79451e
JG		 5062 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
5063 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
43f66a6c
JK		 5064 * were enough free buffers and RX_STALLED is set it is cleared.
5065 *
5066 *
5067 * Driver sequence:
5068 *
bf79451e 5069 * ipw_rx_queue_alloc() Allocates rx_free
43f66a6c
JK		 5070 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
5071 * ipw_rx_queue_restock
5072 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
5073 * queue, updates firmware pointers, and updates
5074 * the WRITE index. If insufficient rx_free buffers
5075 * are available, schedules ipw_rx_queue_replenish
5076 *
5077 * -- enable interrupts --
5078 * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
bf79451e 5079 * READ INDEX, detaching the SKB from the pool.
43f66a6c
JK		 5080 * Moves the packet buffer from queue to rx_used.
