5094  * 0 to 31
5095  *
5096  * Rx Queue Indexes
5097  * The host/firmware share two index registers for managing the Rx buffers.
5098  *
5099  * The READ index maps to the first position that the firmware may be writing
5100  * to -- the driver can read up to (but not including) this position and get
5101  * good data.
5102  * The READ index is managed by the firmware once the card is enabled.
5103  *
5104  * The WRITE index maps to the last position the driver has read from -- the
5105  * position preceding WRITE is the last slot the firmware can place a packet.
5106  *
5107  * The queue is empty (no good data) if WRITE = READ - 1, and is full if
5108  * WRITE = READ.
5109  *
5110  * During initialization the host sets up the READ queue position to the first
5111  * INDEX position, and WRITE to the last (READ - 1 wrapped)
5112  *
5113  * When the firmware places a packet in a buffer it will advance the READ index

5115  * process as many packets as possible, moving the WRITE index forward as it
5116  * resets the Rx queue buffers with new memory.
5117  *
5118  * The management in the driver is as follows:

5121  *   to replensish the ipw->rxq->rx_free.

5123  *   ipw->rxq is replenished and the READ INDEX is updated (updating the
5124  *   'processed' and 'read' driver indexes as well)
5125  * + A received packet is processed and handed to the kernel network stack,
5126  *   detached from the ipw->rxq.  The driver 'processed' index is updated.
5127  * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
5128  *   list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
5129  *   INDEX is not incremented and ipw->status(RX_STALLED) is set.  If there
5130  *   were enough free buffers and RX_STALLED is set it is cleared.
