5038 * When the firmware places a packet in a buffer it will advance the READ index
5039 * and fire the RX interrupt. The driver can then query the READ index and
5040 * process as many packets as possible, moving the WRITE index forward as it
5041 * resets the Rx queue buffers with new memory.
bf79451e 5042 *
43f66a6c 5043 * The management in the driver is as follows:
bf79451e 5044 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
43f66a6c 5045 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
bf79451e 5046 * to replensish the ipw->rxq->rx_free.
43f66a6c
JK		 5047 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
5048 * ipw->rxq is replenished and the READ INDEX is updated (updating the
5049 * 'processed' and 'read' driver indexes as well)
5050 * + A received packet is processed and handed to the kernel network stack,
5051 * detached from the ipw->rxq. The driver 'processed' index is updated.
5052 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
bf79451e
JG		 5053 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
5054 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
43f66a6c
JK		 5055 * were enough free buffers and RX_STALLED is set it is cleared.
5056 *

5059 *

43f66a6c

5062 * ipw_rx_queue_restock
5063 * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
