5047 * ipw->rxq is replenished and the READ INDEX is updated (updating the
5048 * 'processed' and 'read' driver indexes as well)
5049 * + A received packet is processed and handed to the kernel network stack,
5050 * detached from the ipw->rxq. The driver 'processed' index is updated.
5051 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
bf79451e
JG		 5052 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
5053 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
43f66a6c
