JK		 5067 * Rx theory of operation
5068 *
5069 * The host allocates 32 DMA target addresses and passes the host address
b095c381 5070 * to the firmware at register IPW_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
43f66a6c
JK		 5071 * 0 to 31
5072 *
5073 * Rx Queue Indexes
5074 * The host/firmware share two index registers for managing the Rx buffers.
5075 *
bf79451e
JG		 5076 * The READ index maps to the first position that the firmware may be writing
5077 * to -- the driver can read up to (but not including) this position and get
5078 * good data.
43f66a6c
JK		 5079 * The READ index is managed by the firmware once the card is enabled.
5080 *
5081 * The WRITE index maps to the last position the driver has read from -- the
5082 * position preceding WRITE is the last slot the firmware can place a packet.
5083 *
5084 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
bf79451e 5085 * WRITE = READ.
43f66a6c 5086 *
bf79451e 5087 * During initialization the host sets up the READ queue position to the first
43f66a6c
JK		 5088 * INDEX position, and WRITE to the last (READ - 1 wrapped)
5089 *
5090 * When the firmware places a packet in a buffer it will advance the READ index
5091 * and fire the RX interrupt. The driver can then query the READ index and
5092 * process as many packets as possible, moving the WRITE index forward as it
5093 * resets the Rx queue buffers with new memory.
bf79451e 5094 *
43f66a6c 5095 * The management in the driver is as follows:
bf79451e 5096 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
43f66a6c 5097 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
bf79451e 5098 * to replensish the ipw->rxq->rx_free.
43f66a6c
JK		 5099 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
5100 * ipw->rxq is replenished and the READ INDEX is updated (updating the
5101 * 'processed' and 'read' driver indexes as well)
5102 * + A received packet is processed and handed to the kernel network stack,
5103 * detached from the ipw->rxq. The driver 'processed' index is updated.
5104 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
bf79451e
JG		 5105 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
5106 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
43f66a6c
JK		 5107 * were enough free buffers and RX_STALLED is set it is cleared.
5108 *
5109 *
5110 * Driver sequence:
5111 *
bf79451e 5112 * ipw_rx_queue_alloc() Allocates rx_free
43f66a6c
JK		 5113 * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
5114 * ipw_rx_queue_restock
5115 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
5116 * queue, updates firmware pointers, and updates
5117 * the WRITE index. If insufficient rx_free buffers
5118 * are available, schedules ipw_rx_queue_replenish
5119 *
5120 * -- enable interrupts --
5121 * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
