4777 *
4778 * The WRITE index maps to the last position the driver has read from -- the
4779 * position preceding WRITE is the last slot the firmware can place a packet.
4780 *

4786 *
4787 * When the firmware places a packet in a buffer it will advance the READ index
4788 * and fire the RX interrupt. The driver can then query the READ index and
4789 * process as many packets as possible, moving the WRITE index forward as it
4790 * resets the Rx queue buffers with new memory.
bf79451e 4791 *
43f66a6c 4792 * The management in the driver is as follows:
bf79451e 4793 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
43f66a6c 4794 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
bf79451e 4795 * to replensish the ipw->rxq->rx_free.
43f66a6c
JK		 4796 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
4797 * ipw->rxq is replenished and the READ INDEX is updated (updating the
4798 * 'processed' and 'read' driver indexes as well)
4799 * + A received packet is processed and handed to the kernel network stack,
4800 * detached from the ipw->rxq. The driver 'processed' index is updated.
4801 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
bf79451e
JG		 4802 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
4803 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
43f66a6c
JK		 4804 * were enough free buffers and RX_STALLED is set it is cleared.
4805 *
4806 *

43f66a6c
